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 are prepared into automobile interior parts to reduce the amount of VOCs volatilization in the car because of the use of renewable 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.
There are many kinds of automotive composites, including glass fiber mat reinforced thermoplastic composites. Natural fiber reinforced thermoplastic composites and carbon fiber reinforced composites are widely used in seat frames, bumpers, dashboards, engine covers, battery brackets, pedals, floors, protective panels, car ceilings, luggage brackets, sunshades, spare tire racks, etc., with the advantages of high strength, good durability, high reliability, low price, recyclable, degradable, renewable and so on.
It can reduce the harm of cold current, when the temperature in the shed is below ℃ for a long time. Mulch such as straw bag non-woven sunshade net should be covered in the greenhouse at night to prevent frost damage and adopt pot fire or furnace fire to temporarily heat up. Open fire should not be used when heating to prevent smoke damage, and a flue should be set up to keep harmful gases outdoors, focusing on the heat preservation and anti-freezing of vegetables and seedlings in the greenhouse. For eggplant seedlings which are in the early stage of raising seedlings, measures such as artificial light supplement and temperature increase can be taken to prevent freezing injury or excessive growth of seedlings; in cloudy and rainy days, the mulch should be properly removed.
The energy consumption is slightly higher. Therefore, the multi-span greenhouse in the northern region needs to do a good job of heat preservation. Carry out R & D and design in thermal insulation. How to build a three-span greenhouse before determining the use of the multi-span greenhouse for the project, we should first consider the orientation of our region, the climate characteristics, the use of the glass greenhouse. For example, in the glass greenhouse for planting and seedling raising in the northern region, the important work is to maximize the thermal insulation performance of the greenhouse under load. We can add an internal thermal insulation system on the top floor of the greenhouse. The glass around the greenhouse should use double-layer hollow glass as much as possible, and for example, to build a glass greenhouse in the northwest, such as electric sunshade system, electric ventilation system and so on. By adding terminal equipment of the Internet of things, this kind of multi-span greenhouse can automatically start and stop the greenhouse equipment by issuing data acquisition and analysis instructions.
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 glass greenhouse in Tibet 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, window opener, fan, wet curtain and other equipment need to be applied.

Conclusion: after reading this article, I believe you should already know something about the black dots of different sizes of these matrix designs on the edge of the front windshield. Such a black edge design not only improves the beautification effect of your car, but also plays a sunshade role for you when you are driving. When the sun is in direct light, it protects the windshield burst very well, such a small black dot, but it hides a lot of mystery.
Therefore, in the structure of the window, in order to be able to control the illuminating effect of sunlight, the area of the window wall should not be too large. If the window area is relatively large, it should be considered to choose heat reflection glass, endothermic glass or other shading methods, such as eaves, eaves, sunshade panels, window cloths and so on to block the absorption of heat. Improve the airtightness of doors and windows and reduce the number of ventilation in the room. For example, the selection of outstanding airtight doors and windows, or the addition of closed bars on doors and windows can improve the airtightness of doors and windows. Choose the automatic control system. The automatic control system includes energy control of cold and heat source, fresh air volume control, quantity control of air conditioning system, start and stop time and operation mode of equipment, supply air temperature control, temperature and humidity setting control and so on. The automatic control system can complete the convergence management and good control of the air conditioning system, and guess the air state parameters (temperature, humidity, enthalpy, concentration, etc.) in the room surface to keep the indoor environment comfortable.
Windshield sunshade: the summer sun is really fierce, we just walked out of the outdoor soon began to sweat. Similarly, our car closes the doors and windows for a long time, and the enclosed space, coupled with the exposure of the sun, is as muggy as a baked sauna. If coupled with the smell emitted by the car seat, it is really very uncomfortable. But also to our car interior damage, so the car sunscreen needs to be done, we can install this windshield sunshade, can effectively block the sun has a better thermal insulation effect, into the car will not feel particularly muggy!
Chengmai County, Hainan-supplying diesel oil (Lingshui County News) at present, spray-free plastic has been successfully used in side skirts, central control panels, DVD panels, glove boxes, sunshades, dashboards and other auto 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.
