In addition to its light weight, due to the high heat resistance of EPP automotive pillows, polypropylene foam is more advantageous than polyethylene foam and polystyrene foam in areas where higher operating temperatures are required, such as sunshades, instrument insulation panels and areas where the temperature between the doors is easy to rise. However, in addition to the field of energy absorption and heat resistance, polypropylene foam also has good thermal weldability, which makes polypropylene foam is also widely used in car sheds, doors, car * panels, carpet support materials, sound insulation panels, door linings and luggage racks, etc., and its good thermal processing type makes it widely used in control boxes, shock-proof boards and other components. In addition, polypropylene foam can also make steering wheel, door inner panel energy absorption protection pad, buffer pad, headrest, toolbox, cushion, dashboard and so on.
Take camping, for example, how many things you need to carry if you want to hold a high-standard camping, which will probably surprise you. Professional tents that can easily take off for 2,000 yuan, Kermit chairs for thousands of yuan, and tables as small as egg rolls are all the most basic things. They also need picnic mats, sleeping bags, folding cars, sunshades, bright lights, waterproof backpacks, lighting, and even espresso machines and appliances-and large solar charging panels that provide them with electricity.
Configuration: multi-function, sports leather steering wheel, front seat heating and memory function, dual-zone automatic constant temperature air conditioning, rear sunshade, velvet floor mat, high-gloss dashboard, smoking assembly, Bluetooth hands-free and music playback function of mobile phone with USB interface, electric skylight, bi-xenon headlamp brightness adjustment function, LED fog lamp, rain sensor wiper, front glass cleaning without heating, automatic anti-dazzling internal and external rearview mirror Automatic rear door control, light alloy Y-shaped wheels, 17 wheels, low pressure continuous tires, parking assistance system (front and rear radar), tire pressure monitoring and display system, constant speed cruise belt braking function, radar sensor, automatic start and stop function, servo power steering, driving mode control, reflection
Now most cars are equipped with CD equipment, the main factors that affect the normal work of car audio in autumn are high temperature and humidity. Because the car stereo is mostly installed in the upper part of the dashboard, in order to avoid the exposure of sunlight (check transaction price | matching | preferential policy), 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.
China stipulated on October 1, 2007, “the visible light transmittance of the front windshield is not allowed to be less than 70%, and the side window glass is not allowed to post mirror reflective sunshade film.” But in real life, there are often many car owners in order to save money, choose to paste a cheap high imitation film in the automobile supplies wholesale market or roadside shop, but do not realize that this kind of inferior film, not only can not work, but also because it contains formaldehyde, benzene and other harmful ingredients to release harmful substances to the car, damage to the health of passengers, less than two years will fade, but also need secondary film, secondary consumption of
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. The specific heat of the circuit board and plastic components in the car audio mainframe is different, so it is affected by the temperature change to a different extent. In the scorching sun, it is good to use the sunshade to resist the scorching sun and avoid the direct sunlight.
First of all, from the control system of the multi-span greenhouse, the electric sunshade, the electric film, the window, the ventilation, the electric insulation and the water curtain of the electric fan have been realized. The control ability of the greenhouse is more stable and reasonable, and the work efficiency is higher. There is no need for manual operation, just press the switch of the distribution cabinet. Looking at the production in some backward areas ten years ago and even now, this is a great progress for facility agriculture in our country. Secondly, our multi-span greenhouse can be equipped with mechanized automatic fertilizer spraying machine, automatic seeder and even Internet of things control is now a very common system, greatly improving production efficiency and realizing irrigation, fertilization, water and fertilizer saving, soilless cultivation and other protection of soil from pollution.
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 Jilin solar energy greenhouse needs the cooperation of a variety of equipment, with higher and higher 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.
