1. Western hat

Cowboy hat from the American denim is called a kind of commonly wore Mexican denim."Stonson" -style wide -edge high -top felt hat.The top of this hat is depressed down, while the two hat along the two sides rolled up slightly.In addition to the people who wear it, it looks chic and capable, and the denim hat also has many practical functions. It can not only cover the wind, frost, rain and snow, but also the ready -made water scoop, rice bowl, and pillow.The evolution and diversity of cattle hats can be seen in Western movies.The western cattle hat is full of western style, of course, it is also very individual. It creates a male different style, and it is very useful to use it to cover the fierce sunlight in summer.

2. Wide -edge straw hat

The brim of this straw hat hat is wide and large, and there are rural areas.Straw hat is good for ventilation, and it can avoid direct sunlight.

3. mask -shaped sun hat

There are large black hats that can cover the entire face like a welder. In addition to blocking the sun, you can also prevent sand and insects.

4, Baseball cap

The logo of Baseball players is born for exercise.Therefore, it is most suitable for tourism, leisure, and exercise. The long arc with a arc can cover the sun. The adjustable loose band or magic sticker is suitable for different head circumference.Most of the mesh design is used in the second half, which is better permeability.

5.Multi -function hat

Added annexes such as sunshade skirts, hats and ropes, etc. The sunshade skirt can be fixed on the hat tongue to provide a complete Shading effect on the face and neck.It is restored to a ordinary Baseball cap.This hat is available in Outdoor goods stores. Most of them are made of synthetic fibers such as nylon. They are light, durable, fast, and not easy to deform, and they are both beautiful and functional.Suitable for long -term outdoor sports, such as Hiking, climbing, fishing, etc.

Shading coefficient is good or good

The smaller the sunshade coefficient, the better the performance of the sunlight to the indoor radiation.As the state's requirements for building energy conservation are getting higher and higher, as far as the requirements of building glass are concerned, the most important is the Shading (sung) coefficient SC (or SE) and the heat transfer coefficient K value (or U value).The hid coefficient of ordinary glass is about 0.9, so the glass should be processed on the surface, such as thermal reflex glass, low -radiation glass, etc., thereby reducing the shade coefficient.

glass shade coefficient concept description

1. The shade coefficient includes not only the sunlight (300nm-2500nm spectrum) penetrating the glass into the room, but also the energy of the secondary heat transfer of the glass.EssenceThe glass of the glass will absorb the energy of some sunlight, and its own temperature rises. At this time, the glass will be transferred to the room for the second time through radiation and convection.If there is a piece of tea -colored glass, the direct transmission ratio is 50%, and the total transmission ratio of the Solar light is 63%. So 13%of the amount of the glass is the secondary radiation after the glass absorption.

3. The value of the solar energy of the standard 3mm white glass is called the direction ratio, and the value of my country is 0.889, and the international is 0.87. It seems that this difference is not very large, but when it is involved in foreign construction projects involved There should be consensus.Example Calculate the shade coefficient SC = solar energy thermal coefficient (SHGC)/route ratio.When the SHGC is 0.818, the domestic calculation value is 0.92, while the overseas calculation results are 0.94.

3. The sunshade coefficient detects the full spectral energy of the Solar radiation, including ultraviolet light, visible light and near -infrared light in the 300nm ~ 2500nm band. These light shots can produce calories when entering the room.The smaller the sunshade coefficient, the less sunlight entering the room, the smaller the calories that can produce.Low shade coefficient does not directly mean that the visible light transmission rate is also low, because when maintaining the visible light transmission rate, reducing the transmission of near infrared can also reduce the shade coefficient.

4. The shade coefficient is a proportional value of a 3nm transparent glass, which does not mean that the sunlight of the sample glass is always transmitted.For example, when the shade coefficient of the glass is 0.5, it cannot be considered that this piece of glass can enable 50%of Solar radiation heat to enter the room. It should be understood that the Solar calories that the glass can pass through is 50%of the standard 3nm white glass.When the sunshade coefficient of the glass is 1, it means that the total direction ratio of the sunlight of this sample is equal to the standard 3nm white glass.When the shade coefficient is 0, it means that the sample cannot be directly passed through the Solar light through the sun, nor can it be transferred to the solar energy.

5. The heat controlled by the shade coefficient is not the same as the heat control of the heat transfer coefficient. The latter refers to the heat transfer caused by the temperature difference. The former is mainly aimed at Solar radiation.

What umbrella is a pencil umbrella

Pencil umbrellas are very thin in appearance, and their keel is about the same as pencils, so it is described very well, so the pencil is enough to describe the Slim of the umbrella.The "needle" is too much to describe the pencil umbrella, and the first impression is that it is easy to be bad. Is there anyone else to buy, and you dare not use it when you buy it.

In terms of color, pencils, such as color lead and crayons, are colorful, very fresh and beautiful.For umbrellas, I also want to give people such an impression. The colorful lines are like a box of colored lead. They are full of childlike and cute, making people love.For example, in terms of the color of "needle", there is no such impression in the mind of the human mind. It is cold and glowing. If the first impression is the case, it is estimated that no one wants it.

The size specifications of common pencil umbrellas

[Weight]: About 150 grams.

[Specifications]: 50cm 6K, of which 50cm represents the umbrella surface radius of the pencil umbrella, and 6K represents the number of umbrellas of pencil umbrella.

[Fabric]: High -dense polyester wire woven light color cloth.

[Level]: About 21 cm after folding.

[Diameter]: After folding, the diameter is about 3 cm and open about 94 cm.

precautions for Pen Pen Umbrella Buying

1. When buying a pencil umbrella, you should pay attention to whether there is a curl in the pencil umbrella that tells that this pencil umbrella is anti -UV, that is, this pencil umbrella can really prevent ultraviolet rays (the general umbrella cannot resist ultraviolet rays).Of course, there are dual -use pencil umbrellas with both rain and UVs on the market.Usually, the label will be sewn in the umbrella where the skeleton side is leaned on the inside of the skeleton, or it indicates the anti -UV effect on its price tag.

2. A qualified ultraviolet anti -Shading pencil umbrella, even if the most common fabric is made of high -density process, its cost is at least 10 yuan.The so -called sunshade pencil umbrellas that sell a few yuan are obviously counterfeit products.They only painted a layer of inferior reflex coatings on ordinary umbrella surfaces, and naturally they could not achieve better UV effects.

3. The skeleton of genuine Shading pencil umbrellas is made of steel or aluminum -aluminum materials. Although it is fine but strong and tough; the skeleton of the counterfeit pencil umbrella is made of scrap iron, and it will break after a few times.

1. Is the sunscreen effect of heaven umbrellas good?

Paradise Umbrella is a domestic prestigious umbrella produced by Hangzhou Paradise Umbrella Industry Group.Including multiple varieties such as umbrellas, Solar umbrellas.Paradise positives can be sunscreen, and the sunscreen effect is also very good.The real paradise umbrella must be specially coated on the UV umbrella surface.In addition to the fabric itself, the weapon of the sun umbrella sunscreen also has coatings. The coating is divided into upper coating and inner coating.sunscreen coating, the brighter the better; the inner coating is black, because the black Shading effect is the best, in order to maintain the beauty, it is painted inside, but the life of the black coating is only two years.Essence

2. Can heaven and Solar umbrella can drizzle the rain?

Paradise parasols generally cannot rain.If the umbrella surface is not dry after the rain, it can not play a role in preventing UV. When the umbrella surface is wet, due to the optical conduction effect of water, the transmission rate of ultraviolet rays increases, and the protection effect is reduced.Just dry it before using it.

3. How to choose heaven and Solar umbrella

Choose the fabric of the parachute of the heavenly anti -ultraviolet umbrella.Studies have shown that the thickness of the thickness of the umbrella surface is better than the ultraviolet resistance. Generally speaking, the anti -ultraviolet effect of cotton, silk, nylon, adhesive and other fabrics is poor, and polyester is better. Some consumers believe that the more the umbrella surface, the moreThe better the thickness of the thickness of the ultraviolet rays.Secondly, oblique and flat lines.

Relevant experts also remind consumers to recognize the anti -ultraviolet performance logo.At present, the standards at home and abroad generally use the UPF value of the anti -ultraviolet performance of textiles, that is, the ultraviolet protection factor value.The UPF value is the average amount of ultraviolet rays on the average amount of undeyling Skin. The larger the UPF value, the better the anti -ultraviolet performance.Standards that are about to be introduced: Only when UPF> 30 and the UVA's passing rate is less than 5 %, can it be called anti -ultraviolet products and the protection level logo is UPF30 +;When the UPF50 is, it indicates that the product's ultraviolet protection performance is excellent, and the protection level logo is the UPF50.Paradise Umbrella brand Products & GT; & GT;

The development process of the crawler arm Shading

With the development of society and the continuous improvement of people's living standards, people's living conditions have also improved greatly, and villas of various styles have also been completed.People have a private garden and private courtyard, so people have greater demand for beautiful and easy -to -use sunshade products. Various shade can also appear in the domestic market like rain.

Arms

It originated in European and American countries and has developed a history of hundreds of years.Now some economic and developed countries such as Europe and the United States are very common to use the crawling arm cannon, as popular as Chinese families using air -conditioners.It is only a matter of recent years in the Chinese market. First, some foreign brands are sold in China, and some domestic companies have also launched our own brands. This has greatly promoted the popularization of the shade.

Electric trap arm -shaped canopy

It is mainly composed of tunnels, rolls, curvatures, pimple beams, and power mechanisms. The fabrics are generally polyester and acrylic, and the roll Tube is generally aluminum roll.For the production of rolling Tube, electric sunny sheds can produce larger sunshade.The crank arm and the beam are generally aluminum alloy profiles. The power mechanism can be described as a pure electric pipe -shaped motor. It has three forms: manual Tube -shaped motor and the opening of the open -closed Shading.There is a large tensile spring in the crawling arm.Its working principle is: the Shading cloth is connected to the roller and rolled on the roll Tube, connected to the pimple beam, and the arm arm pushes the pimple beam out of the tension spring.You can realize the opening and recovery of the shade.The shade can also control the opening and closure of the shade through the remote control.

In order to make users safely and conveniently use the crawling arm -shaped canopy, some Shading companies apply some new technologies on the arm arm, such as wind, light, and rainy inductors.When the wind power, the weather device system will automatically play a role in recovering the sheets; when the sun falls, the optical sensor system will control the burnt arm of the crawler.The sunbuster is damaged by heavy rain, and the rain sensing system will automatically recover the burnt arm. The Shading has eliminated the user's worries that the user is worried about the severe weather.

The wideness of the bungalus cannon can generally achieve about 2 to 6 meters. The width of the Shading canopy is generally 1.5 meters to 3 meters. A few companies can achieve 3.5 meters or even 4 meters.Shaded scaling canopy.

The shade can not only be used for Shading during the day, but can still be used at night.After the night fell, the family or invited several friends to tast on tea and drink in the home courtyard. At this time, if the Shading canopy can create a warm and romantic atmosphere.

my country's shade canopy industry should be in a starting stage, and there is no national standard or industry standard to regulate the manufacturing and quality inspection of the Shading canopy. Relevant departments have set up the standard of the burnt arm. The unified quality standards and standard market operation mechanisms are presented in front of the world.
