Brief analysis on how to realize energy conservation and emission reduction of building glass film

how to take effective, economic and convenient methods to solve the heat insulation and energy conservation of building glass doors and windows and improve their safety performance

multifunctional glass film is a high-tech energy-saving product that can effectively control solar thermal radiation and increase glass strength. It belongs to a new type of energy-saving building materials

this kind of film is a kind of functional glass film with both light transmission and high heat insulation, which is made of special polyester film as the substrate, coated with various high reflectivity metal or metal oxide coatings by magnetron sputtering and other methods in the middle of the polyester film, and then pressed by a special process composite layer. Now, it can create sophisticated products for customers, such as vehicle aluminum body frames and aluminum alloy stamping parts, which can transform cheap ordinary transparent flat glass into safety and heat insulation glass with multiple colors and functions

for example, it can be directly coated on ordinary transparent glass to become like coated glass to form safety heat insulation glass with multiple colors and functions. For example, the ordinary transparent glass can be directly coated with film to become heat-insulating glass like film glass, and the ordinary transparent glass can be turned into safety heat-insulating glass with both heat insulation and safety explosion-proof functions. Colored or colorless transparent safety film can also be pasted on the curtain wall glass, so that the coating layer of coated glass is not easy to oxidize, fade and fall off, and its ability to resist wind pressure and acid-base corrosion is increased

according to the test of spraying steam or atomized water droplets into the air of the box to achieve high temperature and high humidity, 12mm ordinary glass is pasted with two layers of safety bulletproof film, which can prevent the shooting of 79 micro submachine gun without penetration and splash, which shows its reliable impact resistance. The safety glass made of ordinary glass with safety film has reliable safety performance, low price and can greatly reduce the weight of the glass. The explosion-proof glass made of special safety film pasted on the ordinary glass with a certain thickness can effectively resist the shock wave generated by the explosion when encountering the explosion, reduce the direct injury and the injury caused by the splashing of glass fragments, and also reduce the repair cost of the facilities affected by the explosion and the facilities near the explosion center

according to the test of some domestic research departments, ordinary 6mm transparent glass can make 84% of solar radiation penetrate into the room. In some cities and regions in Western China, the growth of China's plastic machinery industry has ushered in the golden period of Komen's growth and rapid growth in the summer. The radiation flow of the sun into the room in the season is about 1.676 × 106j/m2 · h, when a layer of thermal insulation film is pasted on the 3mm thick ordinary transparent glass, the transmission of solar thermal radiation can be reduced to 82.5%, so that the thermal radiation flow entering the room from the window glass in summer can be reduced from 1.5% Energy efficiency, environmental protection and product quality must be comprehensively considered 676 × 106j/m2 · h reduced to 0.239 × 106j/m2 · h. compared with the heat transfer coefficient of windows, the heat transfer coefficient K of single-layer windows is 5.24w/m2 · K. the heat transfer coefficient is 3.93w/m2 · K when the heat insulation film is pasted on the inner surface of the ordinary glass of single-layer windows, while the heat transfer coefficient can reach 2.04w/m2 · K when the film is pasted on the outer side of the inner layer of the ordinary glass of double-layer windows. Under basic conditions, as a comparative test of the total power consumption of two air-conditioned rooms for 30 days, when the window areas of the two rooms are the same, The building area of the room with thermal insulation film is 13.76m2, and the power consumption is 563.35kw/h, while the building area of the room in the control group (without film) is 14.78m2, and the power consumption is 649.35kw/h, and the room with film saves 13.24% power It can be seen that the heat insulation and energy saving effect is very obvious after the heat insulation film is pasted on the glass of building doors and windows. If the heat insulation film is pasted on the outside of the second glass of the single frame double glass plastic steel window, the heat insulation and energy saving effect is more significant
