laminated glass production
Laminated glass production represents a sophisticated manufacturing process that combines multiple layers of glass with interlayers of polyvinyl butyral (PVB) or ethylene vinyl acetate (EVA) to create a high-performance safety glass product. The process begins with the careful selection and cutting of glass sheets to precise specifications, followed by thorough cleaning to ensure optimal bonding. These glass layers are then assembled with the intermediate polymer layer in a controlled environment to prevent contamination. The assembly undergoes a two-stage process: first, the air is removed through rubber rollers in a pre-lamination phase, then the glass sandwich is heated and pressurized in an autoclave at temperatures around 140°C and pressures of 12-15 bars. This process ensures complete bonding and transparency. The resulting product offers exceptional strength and safety features, as the interlayer holds glass fragments together upon impact, preventing dangerous shards from scattering. The technology allows for various modifications, including acoustic dampening, UV protection, and security enhancement, making it suitable for applications ranging from architectural glazing to automotive windshields and protective barriers.
