The application environment of automobile interior fabric is special, and there are great differences in the performance requirements of interior fabric, such as high wear-resistant polyester fiber used in seat fabric to meet the needs of wear resistance; high light fastness and anti-ultraviolet fiber is used for sunshade curtain or instrument panel coating fabric, and high elasticity and high extensibility fiber is used for commercial vehicle roof with large Radian and door panel with large concave and convex curvature. Special vehicles such as operating buses and school buses have stringent requirements on the combustion performance of interior fabrics, and the main considerations are combustion rate, smoke density and limiting oxygen index; the fabric prepared with high flame retardant polyester fiber can meet the requirements of standards and regulations. In addition, the melt spinning of functional masterbatch and polyester chips prepared by nano-hybrid technology can develop high-performance polyester fibers with different additional functions, such as antibacterial functional fiber, negative ion functional fiber, water-poking fiber and so on.
Many music-loving car owners will install a CD frame on the sunshade to facilitate access to and play CDs, but when the vehicle collides and brakes urgently, the objects in the car will produce inertia, and the discs in the CD rack are also likely to be affected by inertia, flying out to scratch the members of the car, and serious cases may die.
Sunshade as we all know, when we move forward towards the sun in the morning, put down the sunshade to block the too bright light, saying that this does not feel much surprise, then do you know it can still block the sun?
The sun board integrates daylighting, thermal insulation and sound insulation, which can be used for greenhouse, furniture canopy, office sound insulation, outdoor advertising light box and so on. Foreign countries even appeared in addition to the supporting structure, pure polycarbonate material of large-scale lighting house, a sunshine, crystal transparent, warm and pleasant. In terms of greenhouse construction, there are greenhouses built with sunboards, gables and sidewalls using sunboards; as for greenhouses, there are production-oriented greenhouses, trade greenhouses dominated by flower trading centers, and greenhouses dominated by scientific research. Sunpanels are a widely used building material and can also be used in sunshades and canopies.
There is no bulge on the surface of various devices in the car cockpit, the material is soft and elastic, and the sharp corners, protruding edges and protruding parts can be reduced as much as possible, which can reduce the injury suffered by the passengers in the event of collision. The range of interior softening includes prominent accessories such as steering wheel, dashboard, side circumference, roof, seat, floor and sunshade. The steering wheel of some cars can contract during a collision, and some seats have headrest to prevent head injury when the rear is hit. These are all designs that can improve the safety of the car.
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.
ABS resin has been widely used in automobile industry because of its good mechanical properties and excellent molding and processing properties. Such as door panel, instrument panel, auxiliary dashboard, sunshade panel, heat dissipation grille, rearview mirror, car lamp, license plate and so on. ABS plastic plays an extremely important role in automotive products,
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.
Plastic polyvinyl chloride (PVC) material is widely used in the manufacture of decorative skins and protective covers such as automobile dashboards and sunshades because of its low price and simple processing. However, in order to meet the relevant production requirements, PVC formula contains plasticizers of phthalic acid, heavy metals and other toxic substances; in addition, although PVC material itself is non-toxic, it will slowly decompose harmful hydrogen chloride gas at high temperature.
One of the simplest items in the high temperature test is the exposure test, in which the vehicle is parked in the hot sun with the front facing west, and the temperature display patch is affixed to the critical parts of the vehicle, such as engine cover, dashboard, deflector, and so on, and the temperature in the car is as high as 70 or 80 degrees. Then test the door handle, dashboard, sunshade, air conditioning outlet and other internal and external accessories for abnormal sound or efficacy failure.
