Analysis on the application and precautions of glass privacy film in China

[China Glass Net] Private film is a messenger to protect the privacy of your personal space. The Privacy Film is a kind of glass Window film. The private film energy-saving film is an energy-saving glass film specially designed for modern commercial buildings. The privacy film has fashionable and colorful colors, and the excellent one-way perspective effect meets the requirements of modern office environment for fashion and privacy.

It is understood that the superior thermal insulation and energy-saving effect of the private film is in line with the acceptance requirements of the glass curtain wall in the "Design Standard for Energy Efficiency of Public Buildings" of the Ministry of Construction. In addition, the security and anti-riot function of the private film can also protect the personal injury caused by the self-explosion of the glass curtain wall. It is a multi-layered functional polyester composite film material that is applied to the surface of architectural glass to improve the performance and strength of glass, so that it has thermal insulation, heat insulation, energy saving, explosion-proof, UV protection, beautifying appearance, covering Avoiding privacy, safety and safety protection, the glazing film is processed on the multi-layer ultra-thin high-transparency polyester film by dyeing, magnetron sputtering, lamination and other processes. It has super toughness and can alleviate the glass. The low bending strength and the fragility of the impact greatly improve the impact resistance of the glass, and can avoid personal injury caused by cracking and falling off of the glass and spattering of the debris; at the same time, it has functions such as protection and anti-theft.

The building film is made of PET (polyethylene) substrate, leading the use of multi-layer metal sputtering technology and vacuum technology and ion technology as well as thin film physics and fine chemical technology, which makes it have high heat insulation efficiency, high tension and high elongation. Strong resistance to acid and alkali. Moreover, the color is naturally rich, and the test results show that it can block 81% of solar energy; when the outdoor temperature is 38°C-39°C, it is 3.5°C lower than the ordinary glass temperature, saving more than 30% of air conditioning power consumption, which is high-tech and energy-saving. material.

The main purpose of the building membrane is energy-saving and heat-insulating, with UV protection and safety functions. The film can also be classified into a heat reflective film and a low radiation film. A heat-reflecting film that adheres to the surface of the glass to allow visible and near-infrared light to pass through the room, but does not transmit far-infrared light. Therefore, there is enough light to enter the room, and most of the solar heat is reflected back, so that the indoor temperature does not rise too much in the hot summer, thereby reducing the indoor air conditioning load, saving air conditioning costs and energy saving. Low-emission film, which can transmit a certain amount of short-wave solar radiant energy, so that solar radiant heat enters the room and is absorbed by indoor objects; at the same time, it can keep long-wave infrared reflection of more than 90% of indoor objects in the room. Low-emission films can make full use of solar radiation and long-wave radiant energy from indoor objects. Therefore, it can be used for insulation and energy saving in cold areas and heating buildings.
