The importance of glass greenhouse. Temperature is the basic condition to ensure the normal growth of crops. Greenhouse is a thermal insulation agricultural facility for the normal and rapid growth of crops. Heat preservation is an important work in greenhouse agricultural production, so suitable covering materials must be selected. Generally speaking, glass greenhouse is better than glass greenhouse, glass greenhouse can play a decorative role in appearance, and the aging and damage problems of glass greenhouse can be relatively small compared with plastic greenhouse; in terms of performance, due to the complexity of the environment, glass greenhouse can resist various loads (wind load, snow load, etc.). Aluminum alloy (or stainless steel) + plexiglass, ordinary glass, low-cost bamboo ponds and plastic films with beautiful and durable, windproof, rainproof, sunscreen, heat preservation effect and cost, can also be equipped with sunshade and sprinkler system. Plants usually need plenty of light and better glass. Of course, the one-time investment cost of plastics is lower, but the later maintenance cost is also higher, and plastics are easy to age.
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. For more information about Jining intelligent greenhouse, please contact Minghao greenhouse Engineering Construction Company directly.
Generally speaking, the horizontal sunshade with an outdoor south elevation of 45 °can easily cover 68% of the solar radiation heat. Installed in the window inside the curtain, soft 100 pages and other sunshade facilities, most of the solar radiation heat absorbed by it is distributed to the indoor air. The sun visor installed on the outside absorbs most of the radiant heat and distributes most of the outdoor air, thus reducing the impact on indoor temperature. Therefore, the use of external sunshade (sunshade) is the best way to save energy in buildings. Intelligent design of sunshade system.
Although the bag looks small, it can hold a lot of things, even a smaller sunshade can be put down. The opening and closing of the body has a zipper, it is safe and convenient to go out, and its performance-to-price ratio is also quite high.

Because the car audio is mostly installed in the upper part of the dashboard, in order to avoid the exposure of the sun, the effect of using sunshade is better. If the door and window sealing strip is not strict, it should be replaced, otherwise the loudspeaker is easy to rust and damage, or even cause short circuit to burn the main engine. The specific heat of the circuit board and plastic components in the car audio mainframe is different, so it is affected by the temperature change to a different extent. In the scorching sun, it is best to use the sunscreen to ward off the scorching sun and avoid the direct sunlight.
The use of high-quality pc sun plate, but also meet the Jiangyin awning system wind resistance, rain resistance, corrosion and other performance requirements. The combination of glass awning and stainless steel sunshade takes advantage of the fact that stainless steel is a poor conductor of heat. The endurance plate is assembled with high-grade aluminum alloy profiles and supporting accessories. With professional stainless steel screws and other installation accessories to ensure the beauty of the main skeleton. Nantong canopy ceiling lighting material uses pure new imported endurance board, but also can prevent ultraviolet rays, the same reason, the overall wind and rain resistance of PC plate is more reflected in the wind and rain resistance of the whole application project. And has a certain thermal insulation effect. Professional and technical reduction operation design to reduce heavy rain noise. The surface of aluminum alloy canopy profile adopts electrostatic powder technology with strong corrosion resistance.
The exterior sunshade of the building is specially designed, which fully considers the difference between summer and winter, meets the enhanced shading performance in summer and the enhanced heat performance in winter, and greatly reduces the energy consumption of air conditioning and heating in the whole year. Figure 1 shows the exterior sunshade used in the building. The whole building adopts non-thermal bridge design, and the thermal bridge coefficient ψ a ≤ 0.01W/ (m ·K). Figure 2 is a simulation diagram of the temperature distribution of the thermal insulation effect of the peripheral structure nodes.
Third, make full use of all kinds of facilities to create favorable conditions for the growth and cold protection of crops, the greenhouse should do a good job of heat preservation and temperature increase in the greenhouse to ensure immortal seedlings, and actively prepare enough film, sunshade net, straw and other covering insulation materials, in case of freezing weather, do a good job of covering and heat preservation, especially solar greenhouse seedlings, and remove the mulch in time after the strong wind and low temperature to reduce disaster losses.
Car sunshade is currently used more sunshade products, now the market is more commonly used is aluminum film PVC material, this material can better refract light, and PVC internal bubbles have a better insulation heat transfer, can effectively play the role of thermal insulation, then a series of down can be concluded, we choose the material is good or bad to determine the use effect, so we choose the sunshade board Choose a model that can have a sucker, although it is more difficult to place it, but without a sucker, it will easily fall off the windshield, thus losing the meaning of shading and wind shielding. so when we buy this product, try to choose a thicker one, so the effect will be better than the ordinary one.
Changshu Auto Decoration plans to set up a new wholly-owned subsidiary in Hefei, Anhui Province. On September 13th, Changshu Auto Decoration (603035.SH) announced that the company or subsidiary would set up a new wholly-owned subsidiary in Hefei, Anhui Province, with self-raised funds, and the name of the new company would be “Hefei Changchun Automobile Interior parts Co., Ltd.”.
