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.
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, and there are often small molecular harmful substances that do not fully react, while bioplastics, due to the use of renewable raw materials with low toxicity and low harm, greatly reduce the amount of VOCs volatilization in the car after being prepared into automobile interior parts. In addition, this bioplastic can be decomposed to facilitate subsequent recycling, so it is a more environmentally friendly type of plastic.
The main factors that affect the normal work of car audio in 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.
Recently, the temperature has changed greatly. In order to prevent frost damage, it is necessary to strengthen field management and do a good job of anti-freezing and heat preservation. Large areas of open field vegetables, especially leafy vegetables such as green vegetables and spinach, should be covered with non-woven cloth, old plastic film, sunshade net or rice straw before the cold wave of rain and snow. The overwintering vegetables in the greenhouse and the eggplant and fruit vegetables that have been transplanted in the early stage should be timely added to the middle greenhouse, the second film, the small arch shed, etc., take multi-layer covering measures to keep warm, remove the mulch in time in a sunny day, increase the light transmission, and increase the temperature in the shed. The temperature rises at noon and ventilates properly.
Use a sunshade. Direct sunlight is the main culprit that causes leather seats to fade and crack. Put an open sunshade in front of the windshield to protect the leather from sun exposure and extreme heat. As long as the car is exposed to the sun for a long time, turn on the sunshade, such as when parking in the company parking space during the day.
