Exposed to sunlight during the day, the largest heating area is the film coverage, and the largest heat dissipation at night is also the film coverage. Because the film coverage area is larger, so the thermal insulation effect of the film coverage is very important. Therefore, it is necessary to do a good job in the protection of film coverage. The shading system at the top of the greenhouse is divided into external shading, internal shading and internal heat preservation system, which are controlled by computer. The weather station system on the outside of the shed might as well monitor the wind direction and temperature at any time. The configuration of the greenhouse sunshade system is beneficial to the accumulation of reducing heat in the greenhouse, and the comprehensive temperature of crops under the sunshade is actually lower than that directly reflected by the open sun.
Car interior accessories include dashboard, door interior panel, steering wheel, seat, roof, floor mat, sunshade, storage box, ashtray, etc., as well as some ancillary equipment such as audio, air conditioning, communications, television, lighting, etc.; car exterior accessories, including bumper, radiator grille, side anti-collision bar, rear deflector, all kinds of car lamps and lanterns, vehicle glass, and car body accessories such as door handles, wipers, door locks, etc. The functions, shapes and structures of these internal and external decoration components are different, and they are organically combined to form a unified, coordinated and beautiful internal and external decoration system. The materials used in many of these parts are plastic materials. at present, the plastic consumption of many cars in the world has exceeded 120 kg / car, and some models are even higher. The plastic consumption of German Mercedes-Benz luxury cars has reached 150 kg / car. The plastic consumption of some cars in China has also reached 90 kg per car. Figure. 1 shows the current situation of the application of automotive interior decoration materials.
The design of imitation carbon fiber is used in the sub-dashboard and the handle of the four doors, and the handle of the four doors is strengthened to the maximum strength of 45kg, and the element of rivets is added, which not only has a good feel, but also brings strong sense of security for the vehicle when driving on a bumpy road. In the face of the summer sun, the vehicle is also equipped with sunshade curtains, which is really “full of sincerity”.
At present, spray-free plastics have been successfully used in side skirts, central control panels, DVD panels, glove boxes, sunshades, instrument panels and other automotive parts in the automotive field. Bioplastics bioplastics are produced under the influence of microorganisms using original plants as raw materials, such as sugar cane, corn and so on. Commonly used plastics are usually synthesized from petroleum products, and there are often small molecular harmful substances that do not fully react, while bioplastics use renewable raw materials with low toxicity and low harm, so the amount of VOCs volatilization in the car is greatly reduced after being prepared into automobile interior parts. In addition, this bioplastic can be broken down to facilitate subsequent recycling, making it a more environmentally friendly plastic category.
When the weather temperature is relatively high, we can cover the windshield of the car with sunshade. What brand of sunshade should I introduce to you? Recommend several shading and cooling cars, sunshade
