The moisture content of laminated glass film refers to the proportion of moisture contained in the laminated glass film. This parameter has an important influence on the performance of laminated glass.
Generally, when the moisture content of the PVB (polyvinyl butyral) film is in the range of 0.33 to 0.53, the laminated glass can achieve the predetermined adhesive strength and impact resistance. Too high moisture content may affect the cohesiveness and cause bubbles in the finished product; if the moisture content is too low (below 0.3%), the strength of the finished product may be reduced. The SGP (ethylene-methacrylate copolymer) film has a strong resistance to moisture, and it has a good resistance to moisture after being laminated. It does not need edge sealing treatment and does not need to worry about the risk of degumming.
In order to ensure the water content of PVB film, the newly unwound PVB film must be stored in a clean room with a humidity of 23% 28% and a temperature of 2025 ℃ for more than 24 hours, so that the film can be combined when the water content of PVB film meets the requirements.
In general, the moisture content of laminated glass film is an important quality index, which needs to be strictly controlled to ensure the performance and quality of laminated glass.
