ã€The principle of glass insulation film】
The insulation film is coated on its surface with a layer of dark-colored, reflective material that reflects visible light and achieves thermal insulation. The darker the insulation film, the better its effect, but the transparency will be reduced accordingly. It is not recommended to use this film to stick to the front car windshield. The heat insulation film is made by adding a heat absorbing glue or other heat absorbing material to the film, so that it can absorb infrared rays to achieve the heat insulation performance. The thermal insulation performance of this membrane is quite good, but in the process of using it, the membrane absorbs more heat and the temperature itself will be very high, which will also affect its own service life.
The glass heat insulation film is used to add a layer or even a plurality of layers of metal material inside, and is used for reflecting infrared light to achieve the heat insulation performance. However, since it is insulated against infrared rays, it has a very good effect, and has a high light transmittance, and heat insulation can also transmit light.
How to identify good and bad glass insulation film
I. Distinguish between international brands or "OEM"
OEM products 3 kinds of tricks: no manufacturer information, fictitious manufacturers, manufacturers do not have this brand of products.
The real international brand will certainly provide real manufacturer information, especially the internet site of the manufacturer. You can check it through the Internet. After this round, you will find that although there are many brands of insulation film in the market, the real international There are only a few brands.
Second, the inspection agency's certification documents 1, authorized business license 2, quality assurance (original warranty book)
3, the Ministry of Public Security or the security department's test report 4, the national building materials sector's performance test certificate 3, to understand the real product performance 1, safety light transmittance is in line with national safety standards 2, the thermal insulation accuracy of the insulation rate (or (Infrared ray rate) data, and provide test 3, reflect heat or absorb heat (heat absorption means no insulation, and harm the glass)
Fourth, for the front screen glass film, the above three must be excellent at the same time, are indispensable, and in the national regulations, the transparency of the front file must reach 70% or more, so a lot of dyed film is not allowed to be posted to the front file Go.
Xiao Bian concludes: The above introduced the principle of the glass insulation film , I hope to be helpful to everyone. For more relevant knowledge, please continue to pay attention to this website information platform. Follow-up will present more exciting content for everyone.

STAINLESS STEEL PRODUCTS
Stainless steel is a corrosion resistant steel alloy with a minimum of 10% chromium. There are different grades and surface finishes of stainless steel produced to accommodate the environment in which the material will be implemented. Unlike carbon steel, stainless steel does not rust when exposed to air and moisture due to the sufficient amount of chromium present. The chromium creates an invisible passive film of chromium oxide that will not let oxygen attack the surface and prevents rusting of the iron base.
Yuhong Group is a stainless steel manufactory of more than 20 grades of Stainless Steel.
