Domestic architectural laminated tempered glass is recognized as safety laminated tempered glass: tempered laminated tempered glass, laminated laminated tempered glass. Due to the physical properties of self-explosion of tempered white laminated glass, tempered white laminated glass still has potential safety hazards to a certain extent. Compared with ordinary tempered white laminated glass, laminated white laminated glass has more reliable safety performance. It will not fall off by itself after self-explosion or being broken, which can ensure the safety of pedestrians or objects under the building within a certain period of time. Laminated white laminated glass is a combination of two or more toughened laminated glass substrates (tempered or non-tempered toughened laminated glass) sandwiched between them through different lamination processes.
With the advancement of craftsmanship and the needs of design expression, the types of laminated toughened laminated glass have also diversified. The middle layer includes fabric, paper, wood grain, stone sheet, metal mesh, etc. This type of toughened laminated glass takes into account the strength, weather resistance and permeability of the toughened laminated glass itself, and can achieve the designer's creative effect through different color textures in the interlayer.
Of course, the synthesized laminated glass can also be used as a glass substrate, and then further processed into other glasses of various configurations to meet the performance requirements of various projects, such as hollow laminated LOW-E coated glass.
The commonly used laminate films are PVB (polyvinyl butyral) and SGP films. SGP is the trade name named by DuPont in the United States for such products. Its actual material properties are ionic polymer interlayers, which have more excellent physical properties. :
① Colorless and highly transparent;
② Low hygroscopicity, can prevent the intrusion of water vapor
③ Good thermal stability, no degumming at high temperature, and no reduction in bearing capacity.
④ Good light stability, not easy to change color under the action of sunlight
⑤ Good adhesion, sufficient residual bearing capacity after the glass is damaged, and will not fall as a whole
⑥ Has good elasticity, with anti-penetration and vibration absorption functions
Therefore, most of them are recommended to use SGP laminated glass when applying to oversized glass or special parts.
