To reduce the direct radiation of sunlight from the roof, walls, windows and enter the room through windows, eaves, sunshades (awnings), coated glass, etc., can be used to reduce the radiation heat of sunlight absorbed by external walls and roofs, and light-colored exterior wall finishes can be adopted. set the insulation layer on the outside of the external wall and roof, or overhead roof.
Polyurethane foam is widely used in automotive interior decoration and vibration-absorbing parts, such as coating materials, polyurethane rigid plastic plates, polyurethane elastomers, seat soft foam materials, decoration parts, sofa leather, roof accessories; the most widely used is a variety of soft and hard polyurethane foam materials, which have vibration insulation, sound insulation, noise reduction, thermal insulation; PU can also be made into automotive polyurethane coatings, binders, sealants and so on. The PU representative parts on the car are dashboard, rearview mirror, bumper, seat cushion, headrest, steering wheel, instrument panel anti-vibration pad, pillar decoration, front roof lining, window frame, ceiling and side roof frame decoration, door liner, sunshade panel, rear roof frame decoration and so on.
In the middle of summer, car thermal insulation and sunscreen has also become the most concerned thing for the majority of car owners, and many car owners spend money to do “midsummer sunscreen” for their cars. Recently, the reporter visited the market and found that all kinds of automobile sunscreen products such as sunscreen, front window visor, sunshade curtain, car umbrella and so on emerge one after another, and the film business of automobile film shops has also ushered in the peak season, and the automobile sunscreen economy is relatively hot. The reporter searched “car sunscreen products” on Taobao and found that the top seller was car sunshade umbrellas, with monthly sales reaching 100000 +.
However, the effect of indoor shading is not as good as external shading, it only blocks the light, but not the heat. When the light encounters the inner shading facilities, the radiant heat has already entered the room through the glass, and the glass temperature will rise very high. As for the external sunshade, only that part of the sunlight will reach the outer surface of the glass window directly. In general, bright indoor blinds can only block 17% of the solar radiation heat, while the outdoor horizontal sunshade with an elevation of 45 °south can block 68% of the solar radiation heat. The shading effect of the two is very different.
Although the solar greenhouse has a very good thermal insulation performance, but from the point of view of safety, heating equipment is still an important factor. The southern part of our country generally does not need to heat up, but if we encounter bad weather continuously, we still need to use the energy stored in the greenhouse itself, otherwise it will not be able to meet the growth of vegetables. Therefore, whether in the south or north, heating equipment has always been a necessary protective measure. The technical aspect requires that in the equipment configuration of solar greenhouse, the configuration of thermal insulation equipment should be demonstrated in great detail. Of course, the work of Jining intelligent greenhouse requires the cooperation of a variety of equipment, with higher and higher temperature requirements, especially in autumn and winter production, external sunshade system, internal thermal insulation system and window opener and fan, wet curtain and other equipment need to be applied.

In addition to picnics, how to make such activities more comfortable and “classy”? with the help of escalating demand, the form of camping has become a favorite of consumers. Sunshade, delicious food, a few folding chairs, plus barbecue and charcoal fire, in such an atmosphere, not only the activities become more enjoyable, the photos also become more exquisite, which camp scenery is more beautiful, how to wear more film It has become a topic of skyrocketing searches on Little Red Books.
Which do you choose, cars, clothes or sunshades? The professor believes that the two functions do not conflict, the car and clothing is to protect the car from being parked for a long time, while the function of the sunshade is to reduce the direct sunlight into the car, which can reduce the burning inside the car to a certain extent, so that car owners and passengers can quickly enter the car in the hot summer sun, as well as to prevent leather seats and dashboards from being damaged by ultraviolet rays. If conditions exist, both are necessities. If only daily use, a sunshade is also essential.
Manufacturing direction of automotive interior and exterior parts: focus on the development of automotive bumper, front module, skylight system, internal and external rearview mirror assembly, dashboard, center console, battery tray, seat, steering wheel, seat belt, roof interior, door interior panel, column exterior panel and other internal and external decoration products. Tracking and promoting the manufacture of sunshade, air outlet, air duct, instrument panel crossbeam, waterproof film, multi-function sensor cover, threshold trim panel, air guide cover, luggage interior trim, NVH parts, energy absorption block, engine cover heat insulation pad and so on.
It can reduce the harm of cold current. When the temperature in the shed is below ℃ for a long time, the mulch such as straw bag non-woven sunshade net should be covered in the greenhouse at night to prevent frost damage and take basin fire or furnace fire to heat temporarily. Open fire can not be used when heating, in order to prevent smoke damage, it is necessary to set up a flue to put harmful gases outside, focusing on the heat preservation and anti-freezing of vegetables and seedlings in the greenhouse. For eggplant seedlings which are in the early stage of raising seedlings, measures such as artificial light supplement and temperature increase can be taken. Prevent seedling frost injury or overgrowth; cover should be removed properly during rainy days.
Car audio is mostly installed in the upper part of the dashboard and should be protected from sunlight. If the doors and windows are not tightly sealed, they should be replaced immediately. Otherwise, the loudspeaker is easy to rust and damage, and even lead to short-circuit burning damage of the host. In the audio mainframe, the temperature changes to different degrees because of the difference between circuit boards and plastic components. Therefore, in hot weather, it is best to use sunshades to protect against the hot sun and avoid direct sunlight.
Just like a new house needs to start with wall painting, painting and adding furniture in a rough house, so does a new car. In the production process, various parts such as dashboards, carpets, doors and seats, and small parts such as seat belts and sunshades need to be installed, while materials such as polyurethane (PU), organic solvents and auxiliaries are very common in the materials of modern automobile parts. Formaldehyde, acetaldehyde and other VOCs are easily volatilized into the air. At present, most of the VOCs in cars come from dashboard assembly, wire harness assembly and column assembly. With the increase of temperature, the volatilization rate of VOCs will increase in proportion.
