Laminated glass is also known as a penetration-resistant laminated glass.This product consists of three layers.Alayer of polyvinyl butyral(PVB) interlayer film is sandwiched between two glass sheets.It is bonded by high temperature and high pressure to combine the toughness of plastic and the hard-ness of glass.This interlayer film improves the crush resistance,and the thicker the interlayer film,the stronger the glass.Habitually,the sandwich structure is reflected in the name of the product.For exam-ple,the laminated glass of 4+0.76+4 is made of two pieces of 4mm thick glass and a layer of 0.76mm thick PVB interlayer film.
Laminated glass plastic film is a polymer material of formed by the polycondensation of higher mole -cular weight polyethylene and butyraldehyde,and plasticized by plasticizer DHA.This polymer is then plasticized and shaped to become a product.PVB glass interlayer film thickness is generally 0.38mm and 0.76mm.It has good adhesion to inorganic glass,and has the characteristics of transparent heat resistance,cold resistance,moisture resistance and high mechanical strength.PVB film is mainly used of laminated glass.PVB film is mainly used of laminated glass,which increases the crush resistance of glass.Laminated glass has high strength and transparency.
Public places are vital to the protection of the person,and laminated glass can play a big role.Once the laminated glass is broken,the fragments remain stuck to the PVB interlayer film.Althrough it is already covered with cracks,the entire piece of glass remains intact without falling and does not have to be replaced immediately.Therefore,compared with ordinary glass,the risk of personal injury caused by being scratched by broken glass of falling due to glass is greatly reduced.Compared with tempered glass,laminated glass is flexible and has great toughness,It can absorb some impact energy and play aa cettain buffering effect.The strength of high-voltage impact is higher than that of tempered glass, but its mechanical strength and thermal stability are not as good as tempered glass.
Features of PVB laminated glass:
1. High security
2. High security and preventive
3. Sound insulation is good
4. Control sunlight and shield UV
5. Can be decorated and saved
PVB glass performance:
Laminated glass according to the production method of the product,the shape and performance of different types,usually the performance of laminated glass products can be divided into the following categories:bulletproof laminated glass anti-theft laminated glass fireproof laminated glass electric heating laminated glass decorative laminated glass photo-induced interlayer glass electromagnetic shielding glass,etc.
