Can Decathlon sunscreen jacket be washed?

It is not recommended to wash sunscreen.Many people will repeatedly clean the sunscreen clothes. In fact, this is wrong. After multiple washing, the sunscreen coating will fall off, which may cause the sunscreen performance. Therefore, it is recommended to wipe it with a cloth.The effectiveness of play.

Decathlon sunscreen machine washing or hand washing

If you recommend it, it is better to wash it by hand. When the washing machine is cleaned, it is easy to be too hard, damaging the sunscreen ingredients and coating of the clothes. The hand washing is gentle, and the method of cleaning is very simple. It is mainly soaked in the water for a long time.Then rub it gently with your hands, don't be too strong.

Decathlonprecautions for sunscreen and handwashing

1. Use a neutral detergent to open the warm water without more than 30 degrees, and the blisters invade the clothes for not more than 5 minutes.

2. Use soft brush to brush the dirty parts of the clothes.

3. Rinse a lot of water, be sure to wash the detergent composition.

4. Do not screw your clothes and dry it directly in the natural environment, but avoid sunlight.

5. Do not iron it at high temperature, which is the same as the climbing bag.

6. Each washing will have some damage to the clothes to avoid frequent washing.

7. Under the guidance of professional personnel, regularly use professional waterproofing agents to repair and maintain the waterproof nature of clothing.

precautions for Decathlon sunscreen machine washing machine

It is more troublesome for machine washing. Friends with conditions can choose a washing machine with a washing program with professional Outdoor Skin trench coats. This can protect the sunscreen coating of the Skin trench coat for the material of Outdoor clothing.Without this washing machine, you can only wash it by hand.

1. Washing: The washing machine should be able to adjust the appropriate washing rhythm and strength, and avoid washing frost damage and waterproof coating while washing

2. Rinse: The washing machine must have a foam self -inspection technology, which can completely remove the residue of detergent and avoid chemical damage to waterproof coating

3. Dehydration: The washing machine should be able to slowly remove the water in the clothing. When dehydrating, prevent damage to the clothes

4. Drying: The washing machine should be condensed and dry at a low temperature of less than 55 degrees. When drying, avoid high temperature damage and waterproof coating.

Pay attention to the main points of Decathlon sunscreen jacket

1. Select the appropriate cleaning solution

Try not to use laundry powder or alkaline washing supplies when cleaning sunscreen. Since the raw materials of sunscreen are slightly different from the raw materials of other clothes, try to use the neutral lotion solution to avoid the color and color and color of the clothes.Wind -proof functions are damaged.

2. Grasp the tips of cleaning

Pour the neutral washing supplies into the water properly, soak the clothes to about 20 minutes, and gently use our hands. After kneading, we can use soft brushes to sigh with soft brushes.Organize, otherwise it can cause damage to the clothes itself, and it can be dried in a shade after cleaning.

1. What does infrared Telescope mean?

There are many types of infrared. Most of the microcariar night vision also have infrared functions. Its infrared is a short wave infrared, which is longer than visible light, similar to remote control.The purpose of this night vision design is to use infrared lighting, so it is not easy to be discovered (enemy).There is also a thermal imaging. Thermal imaging actually collects the infrared from collecting hot objects. However, this infrared wavelength is very long, and the general microcariae night vision instrument cannot be seen.The advantage of thermal imaging is that it can effectively observe the heat source, such as mammals, cars, etc., which is very useful in military.

2. Principles of Extramaginal Telescope Imaging

You can see the infrared Telescope, which is the band of infrared rays((wavelength8001 000Nm)The Telescope.It is also one of the night viewing Telescopes in military applications.Of course, the infrared Telescope is applied to astronomical observations.The infrared Telescope converts the infrared rays into electronic flow through photoelectric transformation, and then doubles the electrons. Finally, the electrons are hit on the fluorescent screen and turned into visible light.As long as there is temperature, infrared rays will be generated, he is a special lens that can pass and display infrared rays.

3. How much is the infrared Telescope

Like the movie, you can see the enemy clearly at night without light. Only the military active infrared Telescope.Russia is cheap and good quality. Among them4800RMB, if you can buy it in China, it should be in6000above.If it is lower than5000The active infrared night viewing Telescope should be a bit problematic. It is recommended not to buy.

4. Can infrared Telescope be seen through?

cannot.Because our human body has body temperature radiation.No formal manufacturer's manual says that I am"Perspective Telescope".Only said it is night vision Telescope.

Fifth, the red film Telescope is the infrared night vision mirror?

The Telescope, not to mention civilian, military useless Telescopes of night vision, the movie is just a movie.For red or yellow coating, many illegal vendors publicize that "night vision effects, infrared" and the like are actually false propaganda.It is a kind of decoration -has no night vision effect. In fact, this decorative coating also makes the field of vision dark.So except for the previous processed samples, other red film products have not been provided.Although the Telescope of red film, although the brightness and color deflection are not as effective as other coating, because the appearance is good, even as a regular military industry (foreign trade) manufacturer, there are a small proportion of exports.But the problem is that in the domestic chaotic Telescope market, most of the red and yellow -coated Telescopes are not from such regular manufacturers, but some small workshops, in order to deceive the propaganda (so -called "military"/"Russia",/"Japanese cherry blossoms"/"night vision"/"infrared") produced, that is, most of them are inferior products of small workshops.

1. What does invisible pocket look like?

Everyone has heard of the pockets, but friends who have wearing a pocket know that the pocket center of the pocket is concentrated, and the exercise will be slightly uncomfortable. Therefore, there is a invention of invisible waist Bags. So what is invisible pocket?

Invisible waist bag is a type of Sports pocket. As the name implies, it looks like an invisible pocket. This is mainly because it is not a traditional bag design, but a ring.There is a pocket equipped with an invisible zipper, which can be placed on it. If there are not many things, the color of the invisible Belt is the same as the color of the top. It looks like there is no Backpack, so it is called an invisible pocket.

2. Is it easy to use invisible pockets?

The characteristics of invisible waist Bags are beautiful. Because it is inconspicuous, it does not look so obtrusive, but in fact, invisible pockets are also a more practical type of pocket. The advantages of invisible pockets are mainly:

1. Comfortable to wear

The circular storage design of the invisible waist bag can evenly disperse the weight of the items in the waist bag, so that the waist bag is steadily fixed in the waist.And due to the size, the invisible waist bag can fit the waist tightly. The position of the pocket is exactly the position of the Running force, and it can also remind the Running position.

2. Good breathability

Invisible waist Bags are used with hygroscopic sweating fabric (92%polyester fiber, 8%elastic fiber), which can be worn closely. The fabric is soft, breathable, and dry.State.

3. Large capacity

Although the invisible waist bag looks relatively small, the capacity is indeed large. There are four open waist bands. If you put things in the run, you only need to rotate the Belt slightly.In addition to the pockets of the zipper inside the pocket, the inside of the waist bag is connected. This design makes the pocket storage capacity greater, and it is also convenient to freely place different sizes of items.And the sense of load is not strong.

4. security

Putting important cards and documents in invisible pockets do not need to worry about security issues, because the invisible pocket zipper is more damping, and it can avoid the important items in the pockets falling out.

In summary, invisible pockets are still relatively easy to use. If you like outdoor sports, you can also buy an invisible pocket, which is very convenient.

Explain the top ten Telescopes worldwide in the world's top ten Telescope shooting pictures to appreciate

On October 2, 1608, Dutch officials were carefully thinking about a patent application. This is a invention submitted by the owner of the glasses shop owner Hans LipperShey.The object looks like it is around, and it can magnify the objects and scenes through it.This is the earliest concept of Telescope.A few months later, Italian physics and astronomer Galileo took a Telescope for astronomical observation.

The initial Telescope was very simple. It was composed of a very small lens and placed in an internal empty wood pipe with a long arm.However, today, 400 years later, the world's largest Telescope requires built on the towering mountains. Several tons of steel is used to support huge mirrors, so that scientists can observe the vast area of space.In June 2008, at a speech conference held by an astronomer, Dava Sobel claimed that observing space through Telescopes was one of the most outstanding achievements in human beings as a life form.

The following is the top ten largest astronomical Telescopes in the world. The photos of these are the largest optical/infrared Telescopes on the ground.

1. Gran Telescopio Canarias

Gana Large Large Telescope

At present, the world's largest ground basic Telescope is the large Telescope of Gasana. It is located on a small island in Parmaga Islands, Spain. It is said that multiple large Telescopes are placed in the Gaza Islands.The mirror diameter of the Telescope is 10.4 meters, which is composed of 36 custom mirror hexagonal components. The installation requires accurate to a range of 1 mm.It invested a total of $ 175 million, jointly built by the Spanish government, two Mexican research institutions, and the University of Florida.

Before installing the Telescope component, each component was named the name of the gods in the folk legend in the local islands, or named after the island's animals and plants.

Pictures shot by Garn Large Telescope

The last batch of 36 mirror components of the large Telescope of the Gana column was completed. However, its first appearance was in July 2007, when only 12 mirror components were installed.The first star it observes is the "Tycho 1205081" (Tycho 1205081), which is very close to the North Star. After that, this large Telescope has more captured astronomical pictures to shoot a set of interactive galaxies -UGC 10923.The results of each shooting show that the star formation area expands, and the exposure time of the shooting is 50 seconds.

2. Keck Telescope (KECK I & amp; ii)

Kake Telescope

W. M. Kay Telescope is located on the top of Monakia Mountain in Hawaii, 4200 meters above sea level, and Kike I & amp; II is two exactly the same Telescope. They are composed of 36 mirror hexagonal components. The overall mirror diameter is 10 meters.The diameter of each mirror is 1.8 meters, and the thickness is only 10 cm. By actively optical support system, the mirror surface maintains high accuracy.There are three main devices of the Telescope: near infrared camera, high -resolution CCD detectors and high -colored scattered spectrometers.

Each Telescope is 8 floors height and weighs 300 tons. At present, astronomical observation accuracy can reach milliligns.In 1993, the Kike I Telescope was put into use and used scientific observations.In order to use the Telescope for 1-5 nights, astronomers must be approved by the committee in advance and operate the Telescope with the assistance of the committee. Generally, astronomers collect data from the headquarters of the Observatory headquarters in Waimea, Hawaii.

Pictures taken by Kake Telescope

By canceling the distortion and deformation in the atmosphere, the recent adjustment of the adaptive optical system has improved the ground basic astronomical observation ability of the Kake Telescope, and the observation picture is 10 times clearer than before.For example, the Egg NEBULA (Egg Nebula) of the Egg Nebula (Egg NEBULA) is a synthetic picture.When more and more substances on the surface of the star begins to get rid of, the surface becomes more hot, making UV light electricity from becoming a gas, thereby showing beautiful colors under the Telescope observation.The planet can be formed after thousands of years.

3. Large -scale Telescope in southern Africa

A large Telescope in southern Africa, referred to as SALT, is located on a hill on southern Africa. It is the largest single -optical Telescope in the southern hemisphere.It is composed of 91 mirror hexagonal components. The overall mirror is actually effective in diameter of 10 meters.The Telescope can detect the weak light of the moon distance like a candlelight, and the Telescope was first put into use in 2005.Astronomers from South Africa, the United States, Germany, Poland, the United Kingdom, and New Zealand have used large Telescopes in southern Africa.

Pictures of large -scale Telescope in southern Africa

Is this picture showing "the universe Nirvana Phoenix"?In fact, this is the scene of the three galaxies collision mergers. Before the astronomers called this picture "Big Bird", and identified this is just the merger of the two galaxies.It is the result of the collision of the three galaxies, and there is a clear separation material area on the head of the "Big Bird".In order to establish this picture, the large Telescope in southern Africa use its spectrum camera to provide valuable observation materials to the Telescope association, and the spectrum camera can decompose the light into a structure color.This may be used to study the physical condition of the galaxy and the detailed situation of the movement path during the three galaxies.The separation speed of interstellar matter in some areas of the "Big Bird" exceeds 400 km/s.It is very rare to observe such high -speed Running interstellar substances that can be observed in the combined galaxy.

4. Hobbie Enley Telescope

Hobbie Eberi Telescope

Hobbie Enlie Telescope is located in the Favaks Mountain in Texas, USA, referred to as Het, which is very similar to large Telescopes in southern Africa.It is composed of 91 mirror hexagonal components. Each mirror diameter is 1 meter, which is continuously sorted by a small computer control motor.The overall mirror diameter can reach 11 meters, and the actual available is only 9.2 meters.The Telescope can detect cosmic light of 100 million times darker than the human body.Its design and construction adopt a unique way to enable it to absorb large light, especially spectrometers, and its cost is very low.

Pictures taken by Hobbie Enley Telescope

The Hobbie Eberi Telescope can observe the layman star and gamma rays of the Solar system. It is currently used to observe the mysterious substance of the universe that humans cannot see-dark energy.In the three-year special plan "HETDEX" (Hobbi-Eberi Telescope dark energy experiment), the Telescope can observe more than 1 million galaxies from 9 billion light years away, so that it can be drawn to the largest so far so far so farThe universe map.This universe map allows astronomers to measure the expansion speed of the universe in different periods, hoping to reveal the role of the dark energy of different cosmic era. At present, the Telescope will search for the universe area where the Dabei star is overwhelmed.

5. Large dual -Tube Telescope

Large dual -Tube Telescope

Large binocular Telescope is referred to as LBT, which is composed of two tightly adjacent 8.4 diameter Telescopes. They can work separately. When the merger work is like a single, larger Telescope.The first Telescope was set up on the top of the Graham, Arizona, USA in 2004. The second Telescope was installed since 2005. It was not until early this year that the two Telescopes were observed.

Pictures of large binocular Telescope shooting

The first picture was taken in the large binocular Telescope, showing the NGC 2770 galaxy, which is 102 million light years from the earth.This is actually a synthetic picture: the same scene is taken with ultraviolet rays and green light, respectively, showing the activity of stars in the area. At the same time, the red light area shows the older and colder stars.After the merger of such three pictures, a beautiful picture can be formed, which can show the different characteristics of the star body at the same time.

6. 6 Telescope

Telescope

As shown in the figure, this is the half -mountainside of the Mountains of Monakia, Hawaii. The diameter of the Telescope is 8.2 meters. These are a optical/visual infrared Telescope.The mirror surface is thin, and the high imaging quality is obtained through active optics and adaptive optics; the second is to achieve high -precision tracking; the third is to use a cylindrical observation room to automatically control ventilation and air filter, so that the exclusion of hot turbulence can achieve the best conditionsEssenceThis Telescope uses a Serrurier truss to keep the main mirror frame and the auxiliary frame keep parallel in movement.

It can share the observation data of other Telescopes with the Kaike Observatory.It has the largest single -lens in the world today, and its use rights belong to the National Observatory of Japan, but astronomers from all over the world can use it.The name of the Telescope comes from a young star group- "Pleiades".The first scientific observation was conducted in 1999.

Picture of Telescope shooting

This is the gorgeous and clear infrared picture of the S106 star in the S106 star.The maximum quality star in the regional center is called IRS4. It has a history of 10,000 years and its quality is 20 times that of the sun.In addition, astronomers have found that the quality of many stars is lower than the twins in the area, and they are likely to be brown dwarfs.

7. The European Astronomical Observatory is a big Telescope interference instrument

The interference instrument of the southern observatory of Europe

It is a 48.2 -meter diameter Telescope structureCheng, located on Mount Sear Parana, Chile, can operate alone or form a very large Telescope interference instrument.The instruments assembled in the big Telescope can provide detailed observation materials and capture the changes in the star body movement of one billionth.This combined astronomy observation can detect cosmic light 4 billion times more visible than the human body.

Pictures taken by the Da Ling mirror of the Southern Observatory of Europe

Very large Telescope helps astronomers to observe the "fried circle cake" structure shown in the figure, which is considered to be a large quality black hole at the center of many galaxies. Generally, the area near the black hole is very bright.Several Levels of brightness.Indirect evidence tells that astronomers are a gas and dust structure with thick frying circular cakes, which are wrapped in black holes.No one of the astronomers had previously observed the star structure.In 2003, astronomers used very big Telescopes to reveal the mysterious veil of the fried circle cake structure of the NGC 1068 galaxy center.

8. Gemini Telescope

Gemini Telescope is not two tightly adjacent Telescopes. This is two 8 -meter diameter optical/infrared Telescopes, which are located on the east -west hemisphere.The Telescope located in the northern hemisphere is coordinated with other Telescopes in Monakia, Hawaii. The Telescope located in the southern hemisphere is located on Mount Siro Parana, Chile.Place the Telescope in two hemispheres for easy observation of all -weather systems.Its main mirror uses active optical control, and the auxiliary mirror is quickly corrected as an inclined mirror. It will also use the adaptive optical system to make the infrared area close to the diffraction limit.

Picture of Gemini Telescope

It impressed the astronomers.This is likely to be the first picture of the planet surround another star. Astronomers did not eventually determine whether the star actually surrounds a young sun star.If it is a planet, then it will be a behemoth in the planetary family, and its quality is 8 times that of Jupiter.The distance between it is 330 times the distance between the earth-Solar distance. Compared with it, the sea king star in the Solar system is only 30 times that of the earth-Solar distance from the sun.

9. Multi -mirror Telescope

Multi -mirror Telescope

Multi -mirror Telescope is referred to as MMT. Before the main mirror surface is installed, 6 small mirrors are used. This 6.5 -meter diameter main mirror has a specially inferior honeycomb design.The multi -mirror Telescope is an art -level building, and it does not have the dome structure of the traditional observatory.This unique appearance makes the walls, tops, tops and Telescopes of the Observatory's wall, and Telescopes can quickly cool down the Telescope and improve observation efficiency.At present, Multi -mirror Telescope is located on Hopkinson Mountain, Tunson, Arizona, USA.

Multi -mirror Telescope shooting pictures

Because it is in the galaxy, it is difficult to observe the structure of the Milky Way, but the multi -mirror Telescope (referred to as MMT) can help us better observe the "twin brothers" of the galaxy -Triangle Star -based (referred to as M33).Although this galaxy looks very much like the galaxy, it is actually smaller.There are 200 billion stars in the galaxy, while only 10-40 billion stars in the triangle galaxy.Astronomers use multi -mirror Telescopes to establish three -dimensional maps of galaxies, which is conducive to searching for exterior planets and detecting ancient stars in the current period of the universe.

10. Magellan I & amp; II Telescope

Magellan Telescope is currently the latest bilateral Telescope. Two Telescopes are 200 feet apart from the heights of the Atkama Desert in Chile.The 6.5 -meter diameter mirror of the Telescope floats on a high -pressure oil film, and its friction is small, and children can promote this 150 -ton Telescope.However, no astronomer wants to slide the mirror, so driving the cylinder and the driving plane can form a pressure of 10,000 pounds to keep the mirror stable.

Pictures taken by Magellan Telescope

The 8 Zhang Magellan Telescope is combined to form this dazzling picture, which is called "Thor's helmet".This is shot by the spectral camera of the Magellan regional camera using the "Inamori) Magellan regional camera and assembled 8 megapixel CCD detectors.As a result, as a Wolf-Rayet Stars, its surface temperature can reach 25,000-50000 Kai Kai's temperature.

[Selection of tents] How to choose Outdoor tents?

Outdoor Tent selection method

one,Outdoor Tentshape

The Tent takes into account different purposes in design, and there are different styles.As far as the shape of the Tent is concerned, there are five styles of common tents.

1. Triangular Tent: The human -shaped iron pipe is used as a bracket before and after, and a horizontal rod is connected in the middle to support the inner account and put it on the external account. This is the most common Tent style in the early days.

2. Ding -shaped Tent (also known as Mongolian bag): Using double -pole cross support, disassembly is relatively simple, it is currently the most popular in the market

3. Hexagonal Tent: Three or four -shot cross -supported support, and some of them are designed with six shots. They focus on the stability of the Tent. It is a common style of the "alpine" Tent.

4. Found Tent: After supporting it, it can be divided into different support methods of two and three rods. Generally, the middle of the bedroom and the two ends are the room.It is also one of the common Tent styles.

5. Roof -shaped Tent: The shape is like an independent small tile house. The support is usually four corners four columns. There is a spine -like structural roof on it. This Tent is generally tall and bulky.Wild operating Camping is used, so it is known as a car Tent.

two,Outdoor TentSpecification

Manufacturers generally divide the tents into one -person account, two -person accounts, four -person accounts, five -person accounts, six -person accounts, eight -person accounts according to the number of people.Come and choose a Tent that suits size.

three,Outdoor Tentweight

Family Camping tents are generally heavier than tents for climbing. If you want to engage in mountaineering activities, the weight of the Tent is important.If you can't carry it, where do you sleep at night?tents suitable for climbing are usually made of high -tech materials, which are lighter and suitable for highly mobility outdoor activities, but the price is higher; Camping tents usually use general materials, weight is heavy, not suitable for carriers, usually they are usually all.Put it on the car, and then set up after arriving at the destination. The price is relatively cheaper, so you should consider the conditions you can choose when choosing a Tent.

Four,Outdoor Tentcolor

Most people often choose their favorite colors according to their personal preferences, but if they want to reduce the impact on the natural environment, low brightness green and brown puppets are a good choice. In addition to the high -brightness tents, there are alsoThe benefits of easy search.In addition, the color of the Tent will affect the light and temperature inside the Tent. The high brightness of the Tent is high, and the calories transmitted in at the same time will be relatively high;Some of the natural heat sources provided by the sun affect the activities of individuals in the Tent, especially when the weather is not good, they can feel the difference between the two.

five,Outdoor TentTent

At present, the material of the ledger mainly includes glass fiber, aluminum alloy and carbon fiber.The Tube -like glass fiber told rod is currently the most commonly used Tent pole. It may be folded. The account rod is combined through the elastic rope. The head and tail of each account pole are added with aluminum alloy to increase the intensity.However, in a low temperature environment, it is easy to cause rupture of the Tent pole. Once the lever rupture occurs, the support effect cannot be achieved.

The aluminum alloy tilt pole is also a very popular account pole on the market. It adopts the same combination as glass fiber. The weight is the same as glass fiber, but the strength and durability are better.However, it is difficult to repair in case the Tent rod is broken or damaged, so you must bring a spare ledger to prevent it.

The lightweight of the carbon fiber lever. Among the existing accounts, its durability can be said to be the best. It performs well in low temperature environments, but the price is the most expensive among all the lever.

six,Outdoor TentDoor shed

Generally speaking, we do not recommend cooking in tents, because the fabrics of the tents are flammable. Once they come into contact with the fire, they will be burned soon, but what should I do if it rains outside?You can't cook in the rain!Therefore, some Camping tents will have the design of cooking accounts in the door shed. The space is large and small. Most of them are different based on the consideration of weight. Some tents will be designed in import and export.On the other hand, you can also place personal equipment such as personal backpacks, shoes, to avoid being wet by rain. Under the efficient use, you may even have one more living space.

seven,Outdoor TentFabric

The rain cloth or foreign account of the Tent uses waterproof nylon cloth to resist the penetration of rainwater. The waterproof Tent will put waterproof glue on the sewing part to increase waterproofing;Express, but it will have a good breathability.The ground cloth of the Tent is the same as the foreign account, which can prevent the moisture from penetrating from the surface. Therefore, the waterproofness of the ground cloth is very necessary. Be sure to pay attention when choosing.
