| In recent years , the state of construction safety increasingly demanding. The use of safety glass building increasingly wide range , tempered safety glass or laminated glass has the best safety performance in category one, without any kind of safety glass can be compared with the United States . It is widely used in cars, trains, buildings and so on. Tempered laminated glass, derivative products, bulletproof glass is widely used in financial institutions , to operate the security industry has made tremendous contributions. Dry tempered laminated glass Dry tempered laminated , and some use of float glass , and some use made of tempered glass glued laminated glass , float tempered laminated glass sheet is smooth , the production yield, in addition to damage , the general no bubbles , glued layer of whitish and other issues. But generally tempered laminated glass strength is relatively low, safe construction damage is relatively high , following Seoul 's extensive use of many decorative steel tempered laminated glass breakage solve installation problems . This improves the strength of the glass , but because of tempered glass in the glass produced a quenching deformation , to the production of steel laminated glass has brought unimaginable difficulties . Many companies began to thicken solutions tempered glass PVB film is not flat, but in the processing into the autoclave , the glass edge due to faster heat up the glass and PVB thermal conductivity different from the thermal conductivity of the glass and PVB first edge film bonded together so tempered laminated glass in the middle of the gas is difficult to discharge , resulting in a large number of scrap, difficult to use. In that case you can choose to use chemical spray solutions. Dry bending tempered laminated glass Dry bending tempered laminated glass is mainly used for automobile front windshield , before the production process complexity, high cost , preheat preloading process this paragraph absolutely essential , to use sets of silicone, such as preheating vacuum very troublesome , and the finished product rate is not high . The film and glass fixed, directly into the autoclave , which save labor, but also reduce the cost , the yield also increased. Wet tempered laminated glass Wet tempered laminated in addressing bubbles , thermal polymerization product quality and stability , high strength, and dry tempered laminated no difference, while photopolymerization glass quality is unstable. |
