Classification
The glass film is mainly divided into: private film, decorative film, insulation energy-saving film, explosion-proof membrane, bulletproof film, wherein the explosion-proof membrane and bulletproof film belong to a typical safety film. The ranks, but its energy saving effect is relatively poor. Most of the high-end membranes in the market are strong and reliable explosion-proof performance, usually such film glasses are also safe glass. According to the production process, it is mainly divided into: dyeing film, junction film, primary color film, magnetron sputter film. Usually, low-priced in the market is more dyed with a high-filled glass film, and it does not really have functions such as heat-saving and ultraviolet-protection, and the service life is short. It will fall off after two or three years.
Features
The building glass organic film is composite with another layer of polyester film after surface metallization of the polyester film, coated with a wear layer and the back surface thereof in its surface. Applied with mounting glue, and add protective film, mounted to the glass surface to enhance glass safety (anti-impact and support glass debris), or have sunshine control characteristics such as sun radiation heat and block ultraviolet rays. It is a glass organic film with safety and energy efficiency, etc., is a more feasible technical means to improve building glass safety and improve building energy saving effect, enhance the impact strength of non-safety glass, and extend the glass from external force and crushing. Time, it prevents the glass from cracking, splashing, personal injury and property loss. That is, the film glass made of a transparent safety film, although the mechanical strength of the glass itself is not increased, but since the polyester base layer of the membrane has very good toughness and impact resistance, the film will absorb when the film is violently impacted. A lot of impact. And make it rapidly decay, causing the film glass to be broken, still maintaining a good film glass integrity. The main function of the glass adding building energy-saving film is sunshine control, energy saving, safe explosion-proof, blocked glare, blocking ultraviolet, glass surface protection. This membrane has certain safety performance. There are still different requirements for building energy saving power. Its performance indicators include indicators such as visible light projections, visible light reflection ratios, sunshade coefficients, and u values.
Significance
Building energy conservation is an important part of the national energy-saving strategy. To achieve the 20% strategic goal of the "Eleventh Five-Year" development plan, the building energy conservation is the first to build. An important part of building energy saving is the insulation of the wall opening area. The heat loss of the door and window hole in my country is several times even more than ten times in developed countries. In Europe and the United States, the building glass film has become an industry standard. It is increasingly serious The energy crisis makes my country have also begun to promote building glass film. Building glass film is one of the important means of achieving 20% of the "Eleventh Five-Year" energy conservation 20%.
