Qualified laminated glass is PVB film and glass between the close bonding,through high tempertu -re and high pressure made with good transparency and excellent performance of safety glass.When the laminated glass is degummed,the PVB film is separated from the glass and has a gap.Especially ar -ound the edges.This degumming phenomenon is caused by long time exposure of the glass edge in the humid environment,by moisture and atmospheric weathering.The use of waterproof neutral polyu rethane edge sealant around the glass can reduce the degree of moisture weathering of PVB film and prevent debonding.
Safety features:Due to PVB film bonding,laminated glass can avoid falling debris after breakage an -d causing personal injury.Thus people security guarantees.
Security features:Laminated glass can be made into a variety of complex structures,to prevent som e violent incidents to threat of personnel.Such as:Theft and violent invasion;Gun and bullet attacks;bo -mb explosion;Sound insulation characteristics:laminated glass has good sound insulation effect,can reduce the noise interference in the environment;Sunlight control:laminated glass can effectively redu ce the passage of sunlight,prevent glare and block ultraviolet rays;structural properties:laminated glas -s has two structural properties.
It has the same function as the same sheet glass of the same thickness in bearing the lateral wind pressure.Further tests showed that the laminated glass was able to withstand the force of the wind and retain its space when it was cracked by rocks and other factors.
