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 by using original plants as raw materials, such as sugar cane and corn, under the action of microorganisms. Commonly used plastics are generally synthesized from petroleum products, which are often harmful to small molecules that do not fully react, while bioplastics are prepared into automobile interior parts for VOCs volatilization in large vehicles because of the use of renewable raw materials with low toxicity and low harm. In addition, this bioplastic can be decomposed to facilitate subsequent recycling, so it is a more environmentally friendly type of plastic.

Since the condenser of the window air conditioner is air-cooled and located on the outside of the wall, if the sun shines directly (especially at 2: 00 p.m. is the peak time of the cooling load required by the room, and the temperature of the outer wall and the surrounding space is also the highest), it increases the tears on and around the condenser, and the heat dissipation effect of the condenser decreases, resulting in an increase in condensation temperature, resulting in an increase in condensation pressure. The cooling capacity of the system decreases, the power consumption increases, the current increases with the increase of load, and the overload protector is overloaded for a long time, which leads to contact sintering, loss of protection function and compressor burnout. The position of the sunshade should not only block the direct sunlight, but also can not block the hot air out of the air conditioner, so that it can release the heat to the atmosphere without hindrance. The distance between the rear barrier and the window air conditioner should be more than 1.5m. The left and right and upper barriers should be left from the air conditioner! Add coffee and above,

Audio failures are generally divided into two categories: one is caused by improper use, and the other is caused by the weather. Now most new cars are equipped with CD equipment, the main factors affecting the normal work of car audio in late summer and early autumn are high temperature and humidity. 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. With the coming of the rainy season, the humidity increases, and there is often a layer of fog on the surface of CD records, which makes it difficult to read the disc. It is best to scrub it every once in a while. If the CD drive is modified, in order to avoid dampness, do not install it under the floor and seat, preferably on the high part of the car body, but not on the rear windshield, too high temperature will accelerate the aging of electronic components and laser head.

11. After the concrete has been poured, covering or spray curing should be carried out immediately before the initial setting. Concrete thermal insulation materials can be made of plastic film, geotextiles, gunny bags, flame retardant quilts and so on. If necessary, wind shielding shed or sunshade greenhouse can be set up. In the thermal insulation maintenance, the temperature difference and cooling rate of the concrete pouring body should be monitored on the spot, and when the measured results do not meet the requirements of the temperature control index, the thermal insulation maintenance measures should be adjusted in time.
