In addition to automotive glass, is not building glass is also need to do mandatory certification?
The difference between car film and building film:
1. Different types of glial: automotive film is used in ordinary adhesive (HPR) and the majority of the building film for the Qing Dynasty gum (CDF) and the safety film is used more adhesive glue, due to different nature, the life of the car membrane About 3-5 years, while the building film is normally used for 15 years
2. Performance: architectural film of the general performance requirements than the automotive film, so in addition to understand its light transmittance, heat insulation, but also need to understand its reflectivity, U value, shading coefficient and other indicators
3. Metal content requirements are not the same, the volume of cadmium nickel and titanium can not exceed 5%, the building film can not exceed 2.5%, in some requirements only meet the overall requirements of environmental protection, because driving the car is generally adults and healthy people, and people Can not live in the car long-term life, and the building room, including pregnant women, babies, and the elderly sick people, rare metal radiation on the baby's growth there is a certain impact, so the building film rare metal content can not be exceeded, Strict environmental standards.
4. Car film and building film can be separated from ultraviolet light, but the absorption of UV layer structure is not the same, car film separated by ultraviolet layer, is a high-pressure coating of a single layer, building film separated by ultraviolet layer is a vacuum sandwich, containing trace plutonium, can absorb harmful spectrum , Tuned spectral video, car film only in the UV UA play a role in the building film UA and VB are working.
5. Building film and car film thickness is not the same, the building film insulation explosion-proof domestic usually between 2mil-16mil, the general thickness of 2mil, 4mil, 4.5mil, 8mil, 9mil, 12mil, 14mil, 16mil and so on. Domestic thermal insulation film is usually only between 0.8mil - 1.5mil.
Ccc certification
CCC is a national compulsory certification
The country will have the country pumping, if the quality supervision bureau in the market found that your product did not do 3C certification, then they will punish your product for a fine, (this is usually the field of quality supervision made by the punishment), by the local The discovery of the serious circumstances of the direct closure of your plant, the fine are generally 7-8 million look, you can buy this product to do 3 times the certification, and now many buyers also need to do such products 3C certification If you do not have to enter the market
