Electric sunny curtainHow to classify

1. According to the operation principle of the system, it can be divided into "scroll type", "folding type", "blade flip" and so on.

2. Subclassification can be divided into:

(1) FTS scroll -type ceiling curtain (electric sunshade)

(2) FSS scroll -type ceiling curtain (electric sunshade)

(3) FCS folding ceiling curtain (electric sunshade)

(4) folding the dual -track flat -moving system folding sky curtain (electric sunny curtain)

(5) Synchronous motor folding sky curtain (electric sunbath curtain)

(6) Manual/electric folding ceiling curtain (electric sunny curtain)

Method of electric sun -shaped curtain control

1. Cluster control function, cluster general control, regional division control, grading control.The above three types can also be arbitrarily combined.

2. Manual control function, manual switch control, radio remote control, manually add wireless remote control.Some products can be controlled by power -off emergency hand joystick, but only single control can be controlled.

3. Extend the control function to access the total control port of the building.Realize the intelligent control of the entire building, this is more advanced,

4. Intelligent control functions, time and space, risk control, rain control, light control, voice control, this is rarely used, it is a bit limited in operation, or the above 5 arbitrary combinations.For example, wind and rain control, scenery and rain control, and so on.

What are the functions of electric ceiling curtain

1. The improvement of electric sun -shaped curtains on Solar radiation

The insulation and insulation of the peripheral protection structure will be affected by many factors. The biggest indicator of the impact is the sunshade coefficient of the shade mechanism.The high and low shade coefficient will be controlled by the characteristics of the material and the environment.The sunshade coefficient is the ratio of Solar radiation calories generated by the feed structure with Shading measures and the feed structure without Shading measures.The smaller the sunshade coefficient, the smaller the Solar radiation calories of the outer surrounding structure, and the better the thermal insulation effect will be.For example, each of the main facing the windows that the orientation of the window that is measured in South China is: 17%west, 45%south, and 60%in the north direction.It can be seen that the effect of Shading is quite large for blocking the heat of the Solar radiation. The combination of glass curtain wall building and building Shading measures is even more obvious.

2. Electric sunshade can improve the indoor temperature effect

Shading curtains can also prevent the indoor temperature from rising to have a significant effect. Test observation in a west -towing room in South China shows that when the window is closed, there is a Shading curtain and no sunshade curtain.1.4 C.And when there is a Shading, the temperature of the room temperature is small, but the maximum value of the room temperature can be delayed accordingly, so that the indoor temperature is uniform.Therefore, sunny curtains can completely reduce cold loads for air -conditioning rooms. Therefore, the sunny curtain is one of the main and fundamental measures for electricity to save electricity for air -conditioned buildings.

3. The effect of sunny curtains on lighting

From the perspective of natural lighting, the sunshade measures will block the direct sunlight, which can prevent glare and make the indoor light illumination distribution evenly, which helps the normal and relaxed work of vision.For the surrounding environment, the sunshade can be scattered on the reflection light of the glass on the glass curtain wall (especially the coating glass), and after the sunshade, the large -scale glass reflector can cause light pollution.However, because the sunny curtain has a light -blocking effect, it will also reduce the indoor illness, which is a bit unfavorable in rainy days.Therefore, when the Shading system is designed, we must consider it, and try to meet the requirements of indoor natural lighting.

4. The role of electric sun covers on the appearance of the building

In many people, it seems that the building design of the glass curtain wall can only be flat. In fact, there are more and more designs of the sunshade facilities outside the glass top. In fact, from many foreign cases, we can find that metal glass curtain walls can be designed with light metal board design with lightweight metal board design.The beautiful Shading form is a distinctive part of the building shape.The exterior shade system of the building forms a light and shadow effect on the glass wall of the glass curtain wall, which reflects the effect of modern architectural art aesthetics.Therefore, in the European architectural industry, the outer Shading system has been designed as an active facade element as an active facade element, and it is even known as a double -layer facade form.One floor is the facade of the original building itself, and the other is the facade Shading form of a dynamic Shading state.This "dynamic" building image is not because of the fashion needs of the building facade, but a new modern architectural form produced by modern technology to solve human energy saving and enjoying natural needs.

5. The impact of sunny curtains on the ventilation of the room

The Shading facilities have a certain blocking effect on indoor ventilation. When you open the window ventilation, the indoor wind speed will weaken by 22-47%at this time, depending on the situation of the Shading facilities used.The hot air on the surface of the glass also has a blocking effect, which is not conducive to heat dissipation. Therefore, you must pay attention when choosing the structure of the sun.

How to identify the quality of basketball shoes

method

The quality of the identification shoes needs to be focused from the appearance and inner indicators.Because internal indicators often need to use the help of detecting instruments, for a consumer, the quality of the shoe is more practical for a consumer.In terms of appearance, the quality of the shoes is mainly used to identify the quality of the shoe by the quality and work of the shoes (including the upper, the soles, and the shoe).The size can be measured.

1. Upper (help)

shoes are one of the main components of shoes.For light -faced shoes, it depends on whether it is soft and plump. After pressing the upper with your hands, whether the phenomenon of loose surface appears. A good upper should be plump and soft, comfortable to feel, uniform luster, and no loose face phenomenon.For the upper of the fluffy leather shoes, you should pay attention to check whether the fluff is short and uniform, and its color should be consistent.The shoe is part of the shoe gang. It is used to strengthen the upper, prevent the shoe help from extending deformation and improve the foot feel.Therefore, good shoe materials (such as leather shoes) should have good touch, breathability and humidification, and are not easy to discolor.In sewing, wrinkles and Fertilizer should not be available in the shoes.

2. insole

Usually men's shoes are packed in the back half or rear pad.women's shoes are covered with full cushions in the bottom.The insole has the effect of keeping the bottom of the shoe clean and covered with the inner bottom to improve the foot feel.Therefore, insoles should have good suction and dehydration.In terms of workmanship, the insoles should be attached to the bottom of the inner bottom, and there must be no folds of Hanging.

3, outsole

From the perspective of the outside, the binding state around the outsole should be closely glued without gaps, and the bottom surface should be flat.

4. Heel

Whether it is a low heel or a high heel, first depends on whether the cooperation with the shoes is naturally flat.For women's shoes with half high heels.The following two points are more important: First, the heel should be firmly installed on the inner bottom.The front and rear, left and right, should not shake; the second is that the palm surface should not be less than the bottom of the heel.

5. Internal bottom

On the one hand, it is best to look at the inner materials.On the other hand, we must press the waist geardly with your hands, which is equivalent to the back of the toes when wearing shoes.Under the influence of this force, such as the shoe's edge of the mouth is deformed, indicating that the quality of the shoe is problematic.

6. Stability

Put the shoes on the plane, the shoes should be restless immediately. Such shoes are good for stability, which is also one of the basic conditions of high -quality shoes.

Detailed explanation of basketball shoe structure

1. Upper

It is easy to slide and cause lame or other injuries.

2. Shoe help

When choosing a pair of basketball shoes, the first step should be known to know which kind of sneakers you wear will be more comfortable.

High -top sports shoes

About 70%of athletes choose this high -top sports shoes, because this can provide you with the best ankle protective effect.

Powerful offensive athletes and large -scale Running athletes often tend to require stability in this type of shoes.

Gang

If some athletes are seen with speed and felt that high -top shoes have great restraints, then the middle helper is the best choice at the ankle.

Low gang

In regular competitions, only about 10%of athletes wear low -top shoes.This kind of shoes is lighter, but there is no good ankle protective effect of high -top shoes.

3. Material

The age of the upper leather has passed, and it is replaced by a light mixed upper.This upper is usually made of strong, durable leather and breathable, and scratching artificial mesh cloth.This high -tech artificial mesh upper is better durability than leather, and it is generally welcomed by people with better strong and durable in ultra -light materials.

4. Hold your feet

A good hug structure will make your sneakers suddenly jump or stop in the exercise. Frequent Running and quick turn, it is not easy to loosen.

5. Belt

In order to enhance the stability of the shoes, shoelace is also a factor worth considering.Many manufacturers will also continue to design new shoelace structures to increase the stability of shoes.A good lace -up structure can find a suitable comfort, not too loose or too tight, and can be more stable and holding your feet in exercise.

6. Further fix with a strap

Some shoes are characterized by the upper part of the arch of the foot to increase the stability of the leather to increase the stability, and it can protect the ankle and prevent the ankle sprains.

7, zipper

In basketball shoes, it is a fairly new choice to use a zipper structure to protect their feet, and they are often covered under some protective materials.This is a good choice for children who do not have shoelaces. This kind of tearing buckle is not too tired, but it cannot provide good support.

8. midsole

The midsole is the softened and softer and more shock -absorbing effects between the upper and the outsole.It is generally considered to be the most important part of basketball shoes, because the materials and structures he used can affect the different Levels of buffer and shock absorption, which affects the jump of athletes.

9. Shock absorption material

Middle materials are generally made of EVA, compressed EVA, PU, or mixed with these materials.Many basketball shoes of different brands have their own dedicated shock absorption techniques.EVA or compression EVA is relatively light, but stability and durability are not very good. In addition, the compressed EVA may be more durable.

10. PU

It is a more close and durable shock absorption material. He can increase the stability of the shoes, but at the same time, it is even more heavy.

11. Dedicated shock absorption technology

It means that the heels of basketball shoes and the front foot add a certain degree of shock absorption materials while not increasing their weight.

12. Brake and stability

Some basketball shoes use some hard, easy -to -move materials in the center of the shoe or inside the shoes to reduce the rotation of the feet in the shoes.

High -density shock absorption materials will also gradually be used in the inner part of the shoe to increase the stability of the shoe, but if the midsole is too thick, it will often play a negative effect on the stability.So find a pair of basketball shoes with suitable thickness to ensure your shock absorption and stability.

13, outsole

It is a rubber bottom.The outsole of a good pair of basketball sneakers requires sufficient and proper width to protect the ankle without sprained.

The outsole of the tail -shaped pattern is the most common. This outsole can be kept more stable when it is quickly started and stopped.

Most basketball shoes are designed for indoor movements. If you often move outdoors, you should find a pair of more abrasion -resistant bottoms.Some shoes are designed specifically for people who play basketball outdoors, which are more heavy.

14. shoes code

The key to determining whether a pair of shoes is comfortable.Don't guess the size of your current feet based on the size of the shoes you was wearing, because the size of the feet will change at any time.In order to buy a pair of absolute feet, you must determine the size of the foot before buying.
