Laminated glass is a kind of safety glass made of two or more pieces of glass bonded by synthetic resin. The original laminated glass can be ordinary glass, tempered glass, semi-tempered glass, coated glass, heat-absorbing glass, hot-bent glass, etc. The most commonly used intermediate organic material is PVB (polyvinyl butyral), but also methyl methacrylate, silicone, polyurethane and so on. The broken pieces are glued together, and only radial cracks are formed, which will not cause casualties due to fragments splashing. There are currently two main production methods: membrane method (dry method) and grouting method (wet method), but the dry method is currently the mainstream production method.
