two。 Facilities are reinforced. First of all, we should do a good job in strengthening the greenhouse and other facilities to prevent the snow from crushing and collapsing the facilities. If the film is damaged, it should be repaired in time. When there is heavy snowfall, the snow on the facility should be removed in time to reduce the pressure on the facility, increase the light transmittance of the film, and reduce the freezing low temperature caused by melting snow. When removing snow, you should gently push it to avoid piercing the greenhouse film. The greenhouse that is crushed and deformed should be strengthened and repaired immediately. If it cannot be repaired, it should be covered with film, grass curtain or sunshade net in time to improve the heat preservation effect.
Plastic polyvinyl chloride (PVC) material is widely used in the manufacture of decorative skins and protective covers such as automobile dashboards and sunshades because of its low price and simple processing. However, in order to meet the relevant production requirements, PVC formula contains plasticizers of phthalic acid, heavy metals and other toxic substances; in addition, although PVC material itself is non-toxic, it will slowly decompose harmful hydrogen chloride gas at high temperature.
Camry has the advantages of atmospheric appearance and humanized functions, such as various controls on the steering wheel and constant speed cruising, electric seats and sound effects are more satisfactory, the dashboard has a faint blue atmosphere feels good, at the same time, the sunshade is very practical to improve the grade, headlamp cleaning is also more practical, excellent acceleration performance, fuel consumption can also be
This is a high-rise residential building with many levels of changes on the facade and two external shading methods are used on the windows. One is a lightweight perforated metal sunshade picked out from the outer wall, one neatly arranged on the outside of the window, keeping a great distance from the outer wall. This kind of baffle sunshade can effectively block the low-angle sunlight projected from the front of the window. The surface of the sunshade is painted red and stands out on the facade. Another way is that the upper entrance of the window hole and the U-shaped sunshade panels with horizontal and vertical shading on both sides of the window can effectively block the sunlight projected from the front and side of the window. The exterior of the U-shaped sunshade is painted white, in sharp contrast to the red of the metal sunshade.
Car body interior decoration refers to the car interior parts that protect or decorate the human body, as well as car accessories to achieve certain functions, including instrument panels, seats and safety devices, airbags, sunshades, car rearview mirrors, door interiors, floor interiors and other military interiors.
The internal thermal insulation system can be divided into the top and the side, and the principle is to reduce the heat loss in the shed by arranging automatically contractible thermal insulation curtains on the top and side parts, so as to achieve the effect of thermal insulation. At the same time, after the expansion of the internal thermal insulation system, the moisture in the shed is isolated so as to reduce the role of condensed water on the roof. Like the sunshade system, the top internal thermal insulation system is closed by aluminum alloy moving edge, deceleration motor, transmission rack and hot-dip galvanized push-pull rod.
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 Jilin solar energy greenhouse needs 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.
