At first, the study seemed to show that using sunshades was more effective than window masks. Later, it was determined that the sunshade provided insulation only for the dashboard area. In a vehicle without a window film, the average sunshade can only cool the air temperature in the car by about 2 degrees Celsius. A car with a window mask can lower the ambient temperature at the front and rear of the car, cooling the air in the car by about 8 degrees Celsius.
A single material or laminated composite material used in automobile interior parts Such as cushions, seat backs, seat covers, seat belts, headrests, handrails, removable folding roofs, all decorative linings (including door panels, side panels, rear panels, roof linings), dashboards, debris boxes, indoor shelf panels or rear window sills, curtains, floor coverings, sunshades, wheel cover coverings, engine hood coverings and any other indoor organic materials It includes materials such as fillers and cushioning devices that absorb collision energy during a collision.
It can reduce the harm of cold current, when the temperature in the shed is below ℃ for a long time. Mulch such as straw bag non-woven sunshade net should be covered in the greenhouse at night to prevent frost damage and adopt pot fire or furnace fire to temporarily heat up. Open fire should not be used when heating to prevent smoke damage, and a flue should be set up to keep harmful gases outdoors, focusing on the heat preservation and anti-freezing of vegetables and seedlings in the greenhouse. For eggplant seedlings which are in the early stage of raising seedlings, measures such as artificial light supplement and temperature increase can be taken to prevent freezing injury or excessive growth of seedlings; in cloudy and rainy days, the mulch should be properly removed.
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,
Cili in the building to meet the design requirements of the premise, the addition of external sunshade, awning and appropriate increase in the length of the southward balcony can play a certain sunshade effect. Heat-reflecting fabric curtains coated with metal film are arranged on the inside of the window, which has a decorative effect on the front, forming a less mobile space layer about 50mm thick between the glass and the curtains. In this way, a good effect of thermal reflection and thermal insulation can be achieved, but the direct lighting is poor and should be made into a movable type. In addition, installing blinds with certain thermal reflection on the inside of the window can also obtain a certain thermal insulation effect.
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 auto parts. Bioplastics bioplastics are produced under the influence of microorganisms using original plants as raw materials, such as sugar cane, corn and so on. Most of the commonly used plastics are synthesized from petroleum products, and there are usually 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, can significantly reduce the amount of VOCs volatilization in the car after being prepared into automobile interior parts. In addition, this bioplastic can be broken down to facilitate subsequent recycling, making it a more environmentally friendly plastic category.
The interior design mainly includes dashboard, steering wheel, seat, seat belt, airbag, carpet, sidewall interior decoration, sunshade panel, handrail, car rearview mirror and so on. The main design of exterior parts includes front and rear bumper, glass, door anti-collision decoration strip, intake grille, luggage rack, skylight, rearview mirror and so on. Each company may divide these parts into different departments.
However, because the bubble body is a poor conductor of heat, the cooling process often shows that the surface bubble body has been cooled and solidified, while the temperature of the core bubble body is still very high, assuming that the cooling setting ends at this time, although the bubble body has been solidified and shaped on the outside, but the core is still at a high temperature, and its heat will continue to transfer, raising the temperature on the surface of the bubble body. Coupled with the expansion force of the core bubble, it is possible to deform or split the stereotyped bubble. Therefore, for EPP manufacturers, it is necessary to ensure a sufficient cooling setting time for the cooling and curing of foamed products. In areas where higher working temperature is needed, EPP foaming material is more advantageous than PE foaming material, such as sunshade panels, insulation panels of instruments and places where the temperature between the doors is easy to rise.
