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.
Shaoguan pp tank processing drawings at present, spray-free plastic has been successfully used in the automotive field of side skirts, central control panels, DVD panels, glove boxes, sunshades, instrument panels and other automotive parts. 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 components that can be used to lighten the weight of the car are: headrest, dashboard, door lining, steering wheel, tire cover, luggage compartment lining, seat backrest decoration, sunshade, bumper core, air conditioning barrier, carpet support material, roof, side guard, door inner panel energy absorption protection pad, buffer pad, muffler plug-in, rear engine compartment, engine guard.

Greenhouse heat preservation should be done a good shading work, greenhouse heat preservation in the hot season greenhouse vegetable cultivation should adopt shading cover measures, commonly used shading equipment is sunshade, shading should be selected according to plant species. Short plants choose black shading net to choose gray shading in autumn and winter vegetable cultivation. Because the gray shading can prevent the growth of insects, if the seeds or film delay the cultivation of plants need to use the network. On August 7, when the weather is hot, it can be used in the sunshade net, which is relatively weak in the cold season, does not need lighting or no curtain, and does not shade in the heavy rain season. The heat preservation time of the net greenhouse is not long, and the plants are covered on the surface, especially the dark shade opens the daylighting. When growing mushroom crops, greenhouse heat preservation will not cause fungal crop infection, and the products can be recycled.
The warm sunshine room uses strong thermal insulation profiles and glass, and even has auxiliary heating equipment, sunshade system and ventilation system, which can meet the activities, work and living of people who are not affected by the season.
