Many friends will mistake the glass clip as laminated glass. In fact,
it is not. Today, Shandong Tuo Jin will introduce laminated glass to
you.
Laminated glass is a kind of safety glass made of two
or more pieces of glass bonded together by synthetic resin. The
original piece of laminated glass can be ordinary glass, tempered glass,
semi-tempered glass, coated glass, endothermic glass, hot bending
glass, etc. Intermediate organic materials are most commonly used
PVB(polyvinyl butyral), but also methyl methacrylate, silicone,
polyurethane and so on. When the outer glass is cracked by the impact,
the broken pieces are glued together, and only form a radiant crack,
which will not cause personal injury or death due to the flying debris.
At
present, there are two main production methods: film method (dry
method) and grouting method (wet method), but dry production is the
mainstream at present. Classification of laminated glass:
1.
Bulletproof glass. It is composed of multiple pieces of transparent
flat glass of different thickness and multiple pieces of PVB film. This
kind of glass has a high toughness, and when the bomb comes into contact
with the glass, their impact may be weakened to a very low degree or
zero, so they cannot penetrate. General bulletproof glass can be used
for military defense, bank counter guard glass, gold and silver jewelry
and other valuables display cases.
2. Anti-riot alarm
glass. This is a kind of transparent and high strength glass, with
simple tools can not be destroyed, can effectively prevent the
occurrence of theft. It is usually made of multiple layers of high
strength organic transparent material and laminated glass. In order to
give early warning performance, the laminated layer can also be
sandwiched into a wire mesh, and buried with visible light, infrared,
temperature, pressure and other sensors and alarm devices. It is mainly
used for bank vault, weapon warehouse, cultural relic warehouse and
exhibition cabinet, precious commodity counter and so on.
3.
Fireproof glass. It is a new kind of functional material for building.
It has good light transmission and fire retardant performance. Fireproof
laminated glass can be divided into composite fireproof glass and
poured fireproof glass according to the characteristics of the
production process.
