MOISTURE CONTENT INFLUENCE OF LAMINATED GLASS PERFORMANCES
The moisture of QILU®PVB interlayer will directly affect many key performances of laminated glass, not only bond strength, impact resistance, but also influences on the and Stacking bonding and preheating processing, so PVB interlayer moisture content is a pivotal factor in glass laminating process.
For selected well of glass and PVB interlayer film,PVB interlayer moisture content directly affects adhesiveness between glass and PVB film. In fact, adhesion will be effected bond strength and impact resistance of laminated glass units. Adhesion strength and impact resistance which two parameters related to performances of laminated safety glass ,that’s why should control PVB film moisture content strictly, to make sure adhesive force and impact resistance are controlled in safety standards range. To get perfect laminated glass, must control PVB film moisture 0.3%～0.5% in any condition.
