1. How to cool down sunscreen in the sun?

In the summer sun, the sun is exposed to the sun, absorbing the sun, and its internal temperature rises, forming the temperature difference air layer, and the closer the top temperature, the higher the temperature.Although it can be achieved by opening the window ventilation, the effect of cooling down is very small. At this time, you can install Shading curtains on the roof of the sun to shade the heat insulation. The Shading curtains are mainly installed indoors. You can put it away when there is no sunlight.It does not affect the lighting. At present, there are many Shading curtains on the market for owners to choose from.

In addition, when a sunnacle of the automatic control system is installed, it is recommended to increase the installation risk control and rain control sensing device. The light control can be selected according to the specific situation.Manual driving method is generally not suitable for Shading that often unmanned places.The fabric is recommended to use dark (or the dark surface of the fabric faces the Outdoor) to achieve a better Shading effect.

2. What materials are the best for the sun shed

Electric sunshade ceiling curtain:

Dual -track folding ceiling curtain is a dual -track flat -motion Shading system suitable for small glass roofs or family lighting tops. Two types of fabrics are generally used in folding ceiling: one is sunshine fabric and the other is a Shading fabricThen, thenSunshine fabric has the characteristics of blocking the sun without Shading.You can see the blue sky and Baiyun vaguely through fabrics.The Shading fabric is composed of Shading cloth, Shading coating, and temperature.Therefore, the Shading fabric can block the sun and effectively block the Outdoor calories.

The unique guidance load -bearing side track of the folding sky curtain can be arbitrarily bent according to the architectural curve, so as to achieve the perfect combination with the building. At the same time, the manual drive mechanism can be arranged arbitrarily in the direction to meet your various operating needs to a greater extent.

Electric honeycomb curtain:

Also known as Fengqin curtain, it is said that inspiration comes from the most perfect building in the worldThe design of the honeycomb, the unique honeycomb structure, the air is stored in the hollow layer, keeping the indoor constant temperature and heat insulation.Its anti -ultraviolet and thermal insulation functions are effective to protect home supplies, anti -static treatment, and easy washing.The pull rope is hidden in the hollow layer, the appearance is perfect.

The special fabric of the honeycomb curtain is like the hive. The hollow structure can store the air, so that the curtains have the function of maintaining room temperature and isolation of noise.The hive curtain fabrics include water spurs (all -shining), water spurs cloth((Half -ShadingCure, Gauze (half -Shading), ordinary fabric all -shin, semi -Shading, gauze (semi -Shading), etc.The effects of different Shading and heat insulation of fabrics are not the same, mainly depending on the user's love.There are two types of honeycomb fabrics: bee and double bee. The heat insulation effect of double bees is better, but the cost will be higher.The color of the fabric is colorful and colorful. The honeycomb curtain can not only shade the heat insulation, but also the decoration effect is very good, so it is loved by many users.

Third, which is better for electric honeycomb curtains and ceiling curtainsIntersection

The honeycomb curtain will simplify the tedious traditional curtains and lines, giving people a sense of fast -paced and high efficiency. The unique operating system has reliable performance and Smooth operation.The advantage is that when the honeycomb curtain is put away, the position of the window is smaller, so you can get a greater sense of space indoors.

The honeycomb curtain is divided into two types: pulling beads and sunroof types. The vertical surface uses pulling beads to control the curtains to rise and fall. The skylight type is controlled by the handlebage. The honeycomb curtain can only be used indoors.There are silver noodles that can reflect ultraviolet rays and achieve Shading effects. Due to the empty design, the heat transfer effect is used to achieve the heat insulation effect. The honeycomb curtain is divided into single and double peaks.Essence

The answer is certainly not doubt that the hive curtain is good, but the hive Shading is higher than the general ceiling curtain, but since it has spent money to build a sun room, in order to obtain a more comfortable life experience, the sun room Shading equipment belongs to a custom product.It is recommended to install an electric rolling curtain Shading curtain on the top surface of the sun room, and use an electric honeycomb Shading in the sun room. This will bring you a more comfortable sun room experience in winter or summer.

[riding on the knee pads] What is the importance of cycling knees?

What is the use of cycling knees

The ride knee pads are mainly exercise protection. Due to exercise, there is no fierce.There are various postures in the intense exercise. These intense postures easily hurt our knee joints, causing unnecessary damage or strain. Wearing knee protectives can protect the knee well and let the knees exercise during exercise.Keep it stable, while reducing the chance of knee injury.The other is the effect of keeping warm.Human knees are actually very fragile, especially in the cold winter.The role of the knee pad is to keep the knees warm and keep warm. Good warm knee -keeping, can ensure that the blood of the knee joint can circulate well, can resist rheumatism, etc., and prevent injuries when falling. Especially when the elderly go out in winter, wear knee pads.Can protect the knees resist cold wind and protect the elderly's knees from cold.

The braking effect of the knee pads.The knee joint is the place where the upper and lower leg bones are intersecting. There are half -moon boards in the middle. There is a Bone in front. The Bone is stretched by two muscles. It is very easy to slide before the legs of the legs.The influence is not strenuous, so the Bone can move normally in the knee.

Because the riding exercise has put too much pressure on the knee, coupled with the severe exercise in the cycling, it is easy to make the Bone be removed from the original part, which causes the disease of the knee joint.The knee pad can fix the Bone in a relatively stable position to ensure that it is not easily injured.

The above is the mild braking effect of the knee pads when the knee joint is not injured. After the knee joint is injured, the use of severe braking knee pads can reduce the bending of the knee, and maintain it from the thigh to the calf on a straight line to reduce the knee joint.Bending, thereby protecting the knee joint no longer aggravate the condition.

Some cyclists wear knee care while traveling, but often do not wear them short.I do nt know that frozen three feet is not a day s cold . The number of cycling is more frequently. For a long time, the knee joint will still get sick.When the lesion occurred, I regretted it.

The importance of long -distance ride knee pads

Generally speaking, most of the knee injuries are damaged by tissues that are not easy to regenerate because of cartilage and half -moon boards. These tissues do not quickly recover or grow like muscles.Glucose sulfate, but it is not advisable to take too much.Organizations such as cartilage and half -moon board are considered unspeakable for a few years or even more, so doing some targeted muscle exercises will help the rehabilitation and maintenance of knee tissues.However, many people who love cycling and often carry huge luggage Bags have tortured their knees because of high -intensity cycling, heavy load, and wrong riding positions, and finally the root cause.

It is designed with a vest that uses nylon fabrics or neoprene, buoyancy materials or inflatable materials, reflective materials, etc.It is one of the life -saving equipment on the Ship, which is generally vest, and made of foam plastic or cork.Putting on the body has enough buoyancy to make the water falling from the water.

5. Life Rope

It is a kind of swimming pool life -saving equipment.The end can be tied to the life circle, and the pool is used during the life of the pool.The life rope is mainly used for long -distance life -long life. It can quickly rescue those on the shore to increase the speed of life.When the swimming pool life rope is used, one end is tied to the life ring, the other end is fixed on a firm object, loosen the rope and throw the lifebing circle away from the rescue, and then pull it back to the life ring through the life rope.The rope can float on the water, which is generally used in large swimming pools, as well as natural waters (such as rivers reservoirs, sea rescue at sea).

6. Safe bag

Used for life -saving products, such as water cups, medicines, gauze, and so on.

How to use life -saving equipment

When many friends go to swimming in the swimming pool, they will find a strong man sitting on the shore's high chair sitting on the shore.It's a lifeguard.The lifeguard is sitting in a life -saving chair. When a drowning person is found, the drowning person is generally rescued by indirect life -saving and direct life -saving methods.

1. Indirect life -saving

Use some life -saving equipment in the swimming pool to rescue the drowning person. Usually, when the drowning person is stronger than the edge of the pool, the lifeguard pulls the drowning rod to the drowning rod by throwing out the lifebuilding ring or the life jacket.The situation is serious, and artificial breathing and cardiopulmonary resuscitation need to be performed. Urgent treatment is used for emergency treatment, and it is taken to the Hospital.

Principles of the context planning and design of the courtyard

1. Stay on people: convenient people enter and exit and homework; leave 5 to 6 meters in front of the room to benefit the light in the room; leave 3 to 4 meters wide in the back of the house; the main road of the gate of the courtyard is 4 meters wide.

2. See seam pins: The courtyard area is limited, and every inch of land must be fully utilized.The combination of slices and scattered planting.

3. Beautify the environment: the division of the plot, the configuration of the tree species, and the method of planting can be combined with the orchard and the Park.

4. Adapt to the position: Select the appropriate tree species due to the planting location.The tall trees with high value and strong dryness and high -drying of the sidewalk, such as coriander, lychee, longan, ginkgo, persimmon, jujube, etc.;View.

5. Proper dense planting: The courtyard area is not large and can be properly planted to benefit the output rate of the unit area.The pitch of the fruit trees of the garden is 2 to 3 meters and the line spacing is 3 to 4 meters.

6. Planning dense planting: that is, first dense, then thin, take into account the production of the early and later periods.If you plan 2m 2m first, then go to a line everywhere, turn into 4m 2m, and finally become 4m 4m.

7, three -dimensional planting: In order to make full use of land and light energy, three -dimensional planting can be designed.Efficient economic crops between fruit trees and between plants.

8. Three -dimensional cultivation: Raise earthworms or repairs livestock and poultry under the grapes and kiwi sheds.Digging fish ponds in low -lying places, fish farming in the pond, and planting fruit trees.

Choosing fruit trees in the courtyard

Due to the influence of space and environment, the garden planting is different from the selected tree species and production. The following aspects should be paid attention to:

1. In terms of the size of the tree, choose a small tree species and varieties with small trees, short branches, and intermediate pits.The space occupied in this way is relatively small and does not affect indoor light.

2. Should choose tree species and varieties that are early and easy to yield.Early varieties that are easy to manage are generally easier to manage.As a result, early, seeing benefits can improve the confidence and interest of courtyard cultivation.

3. Should choose tree species and varieties with strong pollination capacity.There are many friends planted in the courtyard that the light of the garden is not resulting, but I do not pay attention to this problem.If the courtyard is large, 1-2 pollination trees can also be properly planted.

4. Choose tree species and varieties with ornamental value. Whether it is tree, tree, branches, leaves, flowers, fruits, etc., we must pay attention to this.

Payment of fruit trees in the courtyard

1. Select good varieties

Good breeds are the basis of yield and quality. fruit trees in the courtyard should choose good varieties as a key measure.Generally, you must buy seedlings with high reputation, or buy seedlings from experienced and responsible fruit farmers, so as to be reliable.Do not go to the market to buy seedlings at will. Cause trees are long -term economy crops. The varieties can be benefited for a long time. After the variety is not good, the variety must be pushed down.

2. Later

A variety has its own ecological adaptability, and good varieties must be planted under its suitable ecological conditions to exert its excellent characteristics.Our land belongs to the subtropical climate Belt. Generally, it can only be planted in some fruit trees in the subtropical area, such as citrus, coriander, etc. In the past, a few people introduced tropical bananas, longan and other fruit trees to the cultivation of our land cultivation.That's it.Apple, apricot, and Shou Tao, which are produced in the north, like to dry and cool climate, and are not suitable for development in our land.There are also species that have special requirements for soil pH values, such as chestnuts and bayberry, can only be planted in the loess Belt.However, it is not absolutely divided according to the origin of the origin. Some species have differentiated, such as peaches, pears, and persimmons.Set the planting area of persimmon and fruit trees.

3. planting timely

Evergreen fruit trees such as citrus and loquats like warm and humid climate, and are afraid of freezing damage in winter. Therefore, the planting season should be set in spring, while peaches, Li, pear, grapes and other deciduous fruit trees like dry climate.spring can be available, but it is more suitable in winter. Because the root temperature of these varieties is only 5 C or more, because the soil temperature of the winter in the winter is more than 5 C.The root system is good for the growth of the coming year.

4. Reasonable selection of "neighbors"

Citrus and orange fruit trees are generally not mixed with orange, due to orange susceptible ulcer disease.Peach should not be mixed with Li, because many diseases and Li have many illnesses easily cross -infected.Do not plant cypresses when planting pear trees, because cypress is the winter host of pear rust.
