“the car has been driving for a long time. I always thought that the sunshade on the front of the car could only be in front. It turned out that the bayonet could be turned into a side block after the bayonet was pulled open. However, most people will put towels and invoices here. ”

3. Use a sunshade. Sunshades are like umbrellas for cars, which can block the sun and prevent ultraviolet rays. It can play a good role in protecting the items in the car, such as navigators. When parking, put the front and rear and left and right sides of the car on the sunscreen, which can reduce the thermal effect of solar radiation on the temperature in the car.

Polyurethane foam is widely used in automobile interior decoration and parts that absorb vibration. Its main products are: dashboard, rearview mirror frame, bumper, seat cushion, headrest, steering wheel, control box, instrument board anti-vibration pad, front and rear pillar decoration, middle pillar decoration, front top lining, window frame, ceiling and side roof frame decoration, door liner, sunshade panel, rear roof frame decoration and so on.

Automobile manufacturing industry has always been an important consumer market for polyurethane products. The interior decoration of foamed polyurethane plastic for bridge car includes seat cushion, headrest, sound insulation, dashboard, sunshade, door panel, roof lining and so on. Car polyurethane purchased parts include bumper, flow stopper, front and rear ribbon, grille, rear side plate, door panel, fender and so on. The application of polyurethane in automobile is expanding day by day because of its good plasticity and strong application of material properties.

Another growth factor related to humidity is light. Blueberries are not particularly strong for it, but moderate light is needed to ensure growth. Generally speaking, a sunshade net should be used to isolate part of the exposure when the sun is strong, so as to ensure that the temperature in the blueberry shed should not be higher than 26 degrees. Especially when the summer temperature is particularly high, you can cover two layers of sunshade net on the surface, otherwise the high temperature will make blueberries stop growing. The sunshade net can be removed when the temperature drops in the evening, and if the temperature is too low, the thermal insulation film on both sides of the shed needs to be put down to increase the temperature in the shed. But leave some holes in the perimeter to strengthen an internal air flow. When the weather is bad, one should pay attention to the heat preservation work, and the other is the drainage work.

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 flower greenhouse in Guangxi needs the cooperation of a variety of equipment, with the increasing 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.
