The application of glass film to improve the safety and energy efficiency of common glass can be traced back to 1960. At the time, the original intention of the film was developed. In order to control the imbalance of heating and cooling caused by the solar load, the early film only had the property of reflecting the solar radiation out of the glass window to prevent the heat increase on the inner surface of the glass. With the continuous development of the manufacturing process, a new generation of body coloring film is born, and its rich color provides architects with a broad design space. The main colors are: brown, gray, gold, amber, blue, green, etc. In 1970, the US energy crisis led to the development of another aspect of the membrane to reduce indoor thermal energy loss (ie, "insulation".) The study found that polyester film can not only be used as a transparent medium, but also has the ability to absorb and counter-radiate long-wave infrared. . After trial and error. The material and structure of the membrane have been greatly changed, and the "insulation" of the membrane has been enhanced to produce a "low-radiation membrane" LOWE membrane. The most basic structure of the film is a polyester substrate (PET), one side is coated with a scratch-resistant layer (SR), and the other side is a mounting layer and a protective film. During construction, remove the protective film, and expose one side of the adhesive layer to the inner surface of the glass (if it is specially designed for external film, it is attached to the outer surface of the glass). PET is durable, strong and high. A material that is excellent in toughness, moisture resistance, high resistance, and low temperature. It is clear and transparent, and it is processed by various processes such as body dyeing, metallization plating, magnetron sputtering, and sandwich synthesis. It is a film with different physical properties, which is suitable for commercial buildings, houses, shop windows, bank counters, cars or ships. The needs of the venue. Glass film for construction is mainly divided into two series: building energy-saving film and safety film. The main varieties are: bulk dye film, heat reflective film, low reflection film, high light transmission magnetron sputtering film, low radiation (LOW-E) film, museum and archive film, frosted and translucent decoration Membrane, transparent safety film, etc. Four basic characteristics: heat insulation, UV protection, beautiful and comfortable, safe and explosion-proof. Glass film can be called the “amphibious†product in the construction industry, and it can be used both for renovation of old buildings and for new buildings.
