Glass is the thinnest part inside and outside the car. Because it's thin, so the more direct the transmission of sound and temperature is. Today, our encyclopedia is the heat insulation and sound insulation glass of the car.
Compared with the door glass, the front windshield of a car is stronger. This is mainly because the windscreen is a three-layer structure: two layers of glass, in the middle of which there is a thin film to firmly stick them together. Even if they are broken, they will firmly stick to the fragments and will not fly out to hurt people.
With the development of intelligent automobile and intelligent driving, not only various sensors and cameras related to automatic driving have found new opportunities, but also the PVB intermediate film of automobile glass has begun to find its own "business opportunities".
Select a typical air pillow, and calculate the external load when the air pillow is in different stress state according to the elastic modulus tested in the tensile test, as shown in figure 7.2.5. It can be seen that when the stress of ETFE membrane material is less than 22.5n/mm2, the mechanical performance of the air pillow is basically linear. With the further increase of load, the mechanical performance of the air pillow is nonlinear.
Photocatalyst is a kind of photocatalysis material, which is represented by titanium dioxide. This material can produce free electrons and holes under the irradiation of ultraviolet, so it has a strong photochemical reduction function, can oxidize and decompose various organic compounds and some inorganic compounds, and has a strong bactericidal function.
When using artificial light source, people feel different about the space covered by film at night. If internal illumination is used, the building will become a striking illuminant in the sky at night. Because of the translucency of the membrane material, it is not as effective to irradiate the inner space by irradiating the membrane surface upward. So artificial light at night should only be used on the surface of the film.
