Car sunshade is currently used more sunshade products, now the market is more commonly used is aluminum film PVC material, this material can better refract light, and PVC internal bubbles have a better insulation heat transfer, can effectively play the role of thermal insulation, then a series of down can be concluded, we choose the material is good or bad to determine the use effect, so we choose the sunshade board Choose a model that can have a sucker, although it is more difficult to place it, but without a sucker, it will easily fall off the windshield, thus losing the meaning of shading and wind shielding. so when we buy this product, try to choose a thicker one, so the effect will be better than the ordinary one.

Application scenarios: motor, power system, seat, dashboard, center console, part of the body, front and rear doors, steering column, air conditioning system, skylight, sunshade, tail door and small parts. Lock the noise or leakage of cars, high-speed trains, aircraft, experimental silos, and other indoor areas, or be used to track drones and flight positions, etc.

4. To prevent heat and cool down, many pickup trucks do not have air conditioning, and the dashboards are often scorched in the summer sun. At this time, some drivers will spread wet towels on them, which can play a cooling role. In fact, it is hard to say how much the temperature can be reduced, but at least there is a towel full of cold water in front of you, which will make you feel more comfortable psychologically. Some car owners will also put sunshade pads on the workbench, which can not only improve the appearance of the car, but also cushion the light and make the light look softer, thus reducing the unnecessary danger caused by weak light.

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. News:

Sunscreen is generally divided into sunshade and sunshade, side block, the price difference is about 15 yuan, window shade and umbrella can cover the entire windshield, but can not cover the window, the side block only covers the four windows of the car, suitable for driving or driving when using

Sunshades protect telescopes, reflecting light and background heat from the sun, earth and moon into space. The observatory must maintain a low temperature in order to complete groundbreaking scientific research in infrared light, which is invisible to the human eye and feels like heat.

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.

As a hot automotive supplies, the material of the sunshade is composed of seven layers of materials, wear-resistant and heat-proof, anti-ultraviolet up to 99%, and the optimized material thermal insulation is also increased by 99%. It is found that the heat insulation of the optimized material can be directly reduced by 20 degrees before and after use. such a powerful ability is undoubtedly an indispensable good thing for cars.

After the rubber joint is subjected to pressure for the first time (such as installation and pressure test, etc.) or before it is reactivated after long-term shutdown, the bolt should be tightened again and put into operation. The effective expansion deformation of the bellows of the working main body is used to absorb the size changes caused by thermal expansion and cold shrinkage of pipelines, ducts and containers, or to compensate the axial, lateral and angular displacement of pipelines, ducts, containers, etc. The use or storage of Weihai integrated water processor should avoid high temperature, ozone, oil and acid-base environment. Sunshade racks should be built for pipes used outdoors or facing the sun and the wind, and exposure, rain and wind erosion are strictly prohibited. Paint and winding thermal insulation materials are strictly prohibited on the joint surface. Due to the aging problem of rubber products, it should be inspected and replaced in time. The benefits of this: first of all, the working pressure: the commonly used rubber joint pressure has the same size.

At the Baitikai Zhoujing vegetable base in Waigang Town, Jiading District, the staff raised the roll film to “ventilate and reduce dryness” of lettuce seedlings in the greenhouse. The reporter saw that the completed greenhouse was covered with black sunshade net and silver insulation, and the sprinkler facilities in the shed were opened from time to time to cool down vegetables. Near noon, the outdoor temperature is nearly 40 ℃, while the temperature inside the shed is 15 ℃ lower than that outside. Lettuce seedlings are green and growing happily.
