Important points to choose laminated glass manufacturers
Safety glass refers to laminated glass sheets , tempered glass and hollow glass processed from them that meet national standards. Among them, the comprehensive performance of laminated glass and insulating glass made of laminated glass is the best.
classification
General tempered glass for civil use is made by heat treatment process to increase the strength of ordinary glass by 3-5 times. It can withstand a certain energy of external impact or temperature change without breaking. Even if it is broken, the whole glass is broken into small particles with obtuse angles like honeycomb , It is not easy to hurt people, so it has a certain degree of safety. Tempered glass cannot be cut, it needs to be cut to size before tempering, and it has "self-explosion" characteristics. According to different uses, tempered glass can be divided into full tempered glass, semi-tempered glass, regional tempered glass, Flat tempered glass, curved tempered glass and other types.
As a kind of safety glass, laminated glass, after being broken by impact, will not cause sharp fragments to hurt people like ordinary glass due to the adhesion of the PVB film sandwiched between two ordinary glass. At the same time, the sound insulation and sunlight control performance of its PVB interlayer makes it a new type of building material with energy saving and environmental protection functions: the use of laminated glass can not only insulate the consistent noise of 1000 Hz-2000 Hz that can penetrate ordinary glass, but also And it can block more than 99% of ultraviolet rays and absorb heat in the infrared spectrum. As a laminated glass that meets the performance of new building materials, it is bound to play a huge role in the use of safety glass.
Application advantage
Whether the sound insulation of modern rooms is good or not has become one of the important factors for people to measure the quality of housing. Laminated glass using Saflex? PVB interlayer can block sound waves and maintain a quiet and comfortable office environment. Its unique ultraviolet filtering function not only protects people's skin health, but also makes valuable furniture and displays in the home get rid of the bad luck of fading. It can also reduce the transmission of sunlight and reduce cooling energy consumption. The many advantages of laminated glass will have unexpected good effects when used in home decoration. For example, many family doors, including kitchen doors, are made of frosted glass. The cooking fume in the kitchen tends to accumulate on it when cooking. If you use laminated glass instead, you won't have this trouble. Similarly, the large area of glass partitions in the home is a safety hazard for children who are naturally active. If laminated glass is used, parents can feel relieved. Even if the glass is broken, broken pieces and sharp small pieces still stick to the intermediate membrane.
Production Process
LED glass is also called photoelectric glass, Power Glass, is a perfect combination of LED light source and glass, and breaks through the traditional concept of building decoration materials. The pattern can be designed in the glass in advance, and the controllable change can be realized through DMX all-digital intelligent technology in the later period, and the brightness and change of the LED light source can be freely controlled. The interior uses a completely transparent wire, which is different from ordinary metal wires, and no wires can be seen on the surface of the glass; after special treatment in the later period, both the technical requirements and the safety requirements have reached the relevant national certification standard.
safety standard
National standard GB9962, European standard CE (including EN standard), ANSI,...
Compliance with glass materials:
①Float glass: GB11614;

④ Tempered glass: GB/T9963;
⑤ Heat-absorbing glass: JC536;
⑥ Semi-tempered glass: GB17841;
⑦Type III laminated glass sheets does not use wired glass and tempered glass.
Shopping points of choose the laminated glass sheets manufacturers
Look at the logo and check the certificate
Since safety glass product certification was launched in 2003, most of the building laminated glass manufacturers across the country have passed product certification. The company must silk-print or paste the 3C mark on the product itself, or put the smallest outer packaging and accompanying documents on the product. (Such as the certificate of conformity) add the 3C mark. When purchasing a product, you must first check whether there is a 3C mark, and check whether the purchased product is within the scope of the company's compulsory certification capability and whether the certification certificate is valid based on the company information, factory number or product certification certificate. To
Look at the appearance to check the quality
Check the appearance quality of the product, the laminated glass sheets should not have cracks or degumming; the length or width of the burst edge should not exceed the thickness of the glass; scratches and abrasion should not affect the use; bubbles, impurities or other observables in the middle layer Defects such as opaque objects should not exceed the requirements of GB/T 15763.3.
During use, avoid external impact as much as possible, especially for tempered laminated glass to avoid the impact of force on the tip. When cleaning the glass, be careful not to scratch or scratch the surface of the glass, so as not to affect its optical performance, safety performance and aesthetics. The laminated glass should be installed with neutral glue, and contact with acid glue is strictly prohibited.
