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.
In terms of transport, the plastic used by vehicles, trains, ships and other means of transport and corresponding ancillary facilities is increasing year by year on a per-vehicle basis or per-vessel basis. Varieties include fuel tank, bumper, sunshade seat, door handle, steering wheel, dashboard and so on. As a new type of packaging material, plastic has been widely used in the field of packaging. For example, a variety of hollow containers, injection containers (turnover boxes, containers, buckets, etc.). Packaging film, woven bags, styrofoam, binding rope and packing straps, etc.
Most of the car is made of delicate leather, metal and wood, needless to say the degree of meticulous workmanship. The dashboard connects with the wooden veneer of the car door to form a continuous curve, creating a sense of intimacy similar to sitting in the living room at home. All the wood decorations are made by hand, then hardened for 72 hours, and finally coated with varnish, so that the natural beauty of the wood can be better presented. The new interior contains 600 new parts, while a few parts, such as sunshades, door handles and seat armrests, are the same as those of the previous generation.
In addition, I also know a series of useful automotive supplies, of course, I have not bought it myself, such as car hood, sunshade for front windshield, steering wheel cover, inflatable pump, and wiring, which are actually quite practical and inexpensive.
Car interior parts include dashboard, door inner panel, steering wheel, seat, roof, floor mat, sunshade and so on. The surface of the interior decoration should be smooth, wear-resistant, heat-resistant, low-reflective, sound-absorbing and masking, and it is not easy to volatilize toxic gases in direct sunlight. At present, the amount of plastic used in automobile interior parts has accounted for more than 50% of the plastic consumption of the whole vehicle. PP is used as the main raw material to make a new type of automobile dashboard, which not only has good comprehensive properties such as toughness, strength and appearance, but also reduces the automobile cost, so it is widely used on the automobile dashboard. Nearly half of the materials made by European companies for automotive dashboards use PP, and this trend will continue to grow.
Loquat in open field can be covered with sunshade net, straw and other anti-freezing measures at low temperature at night. If part of the citrus is left on the tree, it should be harvested in time. If it is too late, you can pick the upper part and leave some of the lower part of the fruit. In these two days of freezing or frost, you can also cover some sunshade nets, ground cloth, straw and so on, to delay the heat preservation of oranges in the greenhouse.
When the sun shines on the sunshade, some of the heat will be blocked, and the ultraviolet light will be reflected by the aluminum foil. Car sunshade can prevent leather seats and dashboards from being damaged by ultraviolet rays. Direct exposure to the sun will make the temperature in the car as high as 70 degrees. Not only the shell of the central console is easy to deform, instruments and other equipment on the dashboard are also damaged by high temperature, such as aging components, pin soldering, etc., sunshade can effectively avoid direct sunlight.
