What is the difference between "wet process" and "dry process" of laminated glass?
Laminated glass is generally installed on the glass roof of the sun room. Now it has been used more and more on the facade glass of the door and window curtain wall, especially for the sound insulation of doors and windows. Therefore, the laminated glass is also divided into many production processes. Among them, it is divided into dry laminating and wet laminating. What is the difference in the effect of the laminated glass made by these two processes?
That is, a PVB interlayer film containing polyvinyl butyral as a main component is sandwiched between two glasses. The thickness of the laminated rubber is generally above 0.38. It is dehumidified by film, dried and treated at a constant temperature. After washing and drying, the pvb film is laid, the film is pressed, the air is squeezed out and the two pieces of glass are firmly combined, and then fixed by high temperature and high pressure. Forming, each process can not be taken lightly. After the finished product, it has the function of reflecting sound waves. The function of noise reduction and noise reduction is installed on the door and window. Even if the glass is broken due to collision, the debris will be stuck on the film, and the broken glass surface will remain neat. smooth. It effectively prevents the occurrence of debris pitting and penetrating fall events, ensuring personal safety. Strong resistance to penetration.
The dry laminating process is complicated, the safety factor is high, and the service life is long.
