Laminated glass, also known as laminated glass, is made from two or more pieces of glass through the addition of organic polymer intermediate membrane. It has many advantages through special treatment. Laminated glass is superior in performance and has many advantages. According to the difference between the glass used and the intermediate membrane, the laminated glass can meet the requirements of various occasions.

1. What are the advantages and disadvantages of laminated glass
Laminated glass is sandwiched between two pieces of glass into a PVB middle film with polyvinyl butyral as its main component. Even when glass is broken, the fragments will be stuck to the film, and the broken glass remains clean and smooth. This prevents the broken and penetrating events of the fragments and ensures the safety of the human body.
In Europe and America, most building glass uses laminated glass, which is not only to avoid injury accidents, but also because of the excellent anti-seismic intrusion ability of laminated glass. The middle film can resist the continuous attack of hammer, chopper and other weapons, and can resist the penetration of bullets for a long time, and its safety precautions are very high.
Modern living room, sound insulation effect is good, it has become one of the important factors to measure the quality of housing. Using the laminated glass of PVB middle film can block sound wave, maintain quiet and comfortable office environment. Its unique filter ultraviolet function not only protects the health of the people's skin, but also makes the valuable furniture and display products in the house and so on. It also reduces the transmission of sunlight and reduces the energy consumption of refrigeration.
The disadvantage of laminated glass is that the glass is saturated with water, and the water molecules are easier to enter the glass interlayer so that the surface of the glass is blurred.
There are many advantages of laminated glass, which can not be expected in the home decoration. Many family doors, including the kitchen door, are made of sanding glass. The cooking fumes in the kitchen are easy to be deposited on it. If they are replaced with laminated glass, there will be no trouble. It is a hidden danger for children who are naturally active. If you use laminated glass, parents will be relieved greatly.
The laminated glass breaks down safely and can be broken under the impact of the heavy ball, but the whole glass remains intact. The fragments and sharp small fragments still stick together with the middle membrane. When the glass is broken, the fragments are not dispersed and are used on vehicles such as cars.
Toughened glass needs greater impact force to crush. Once broken, the entire glass will be broken into numerous fine particles, with only a few broken glass in the frame.
Ordinary glass smash when it hits, typical breakage, resulting in many long sharp fragments.
When the broken glass is broken, the mirror tooth shaped debris surrounds the opening, and there are more glass fragments around the point of penetration.
2. What is the difference between the laminated glass and the hollow glass
Laminated glass and insulating glass are made up of two or more than two pieces of raw glass, but they are different from each other.
Laminated glass is made of two or more than two pieces of glass. The laminated glass is sandwiched with transparent plastic lining and is made by hot pressing. The original glass is made of ordinary flat glass or float glass. The lining is made of polyvinyl butyral and other plastic films. The laminated glass is divided into flat glass and laminated glass in shape. For superior and qualified products.
The insulating glass is made of two or more pieces of glass, separated by a isolation frame around it and sealed with sealant to form a dry air layer between the glass layers. The glass plate is laminated, tempered, endothermic, heat reflective, and embossed glass. The sealant must be sealed with a double component sealing adhesive and must meet the insulating glass performance requirements. Spacer frame must be met. Aluminum frame and stainless steel frame can be used. Hollow glass is square and rectangular in plane shape. The outer surface of hollow glass requires that the inner surface of the hollow glass shall not have a splash of adhesive. The inspection items of the sealing, dew point, ultraviolet radiation, climate circulation and high temperature and high humidity of the hollow glass must be qualified, otherwise the inspection items must be qualified, otherwise the inspection items of the insulating glass must be qualified, otherwise the inspection items of the high temperature and high humidity must be qualified, otherwise They are judged to be unqualified.

3.1 hollow glass
The hollow glass was invented by the American in 1865. It is a new type of building material with good insulation, sound insulation, beauty and application, and can reduce the weight of buildings. It is made of two pieces (or three pieces) of glass with high strength and high gas tightness compound binder, and the glass sheet is bonded with the aluminum alloy frame containing dry dry agent. Efficiency insulation glass. The insulating glass is superior to the ordinary double glazing. Therefore, it is recognized by all countries in the world. The hollow glass is a glass product with two or more pieces of glass to be effectively supported by the effective support and the surrounding adhesive seal to make the glass layer form a dry gas space. Its main materials are glass, aluminum spacer, corner bolt, Ding Ji rubber, polysulfide glue and desiccant.
3.2 laminated glass
Laminated glass, also known as sandwich glass and vacuum glass, is made of two or more pieces of glass, sandwiched by a layer or multi layer organic polymer intermediate film. After special high temperature prepressure (or vacuum pumping) and high temperature and high pressure processing, the glass and intermediate film are bonded into a composite glass product. Laminated glass is usually PVB, SGP, EVA, PU and so on. The laminated glass of color middle membrane, SGX type laminated glass, XIR type LOW-E laminated glass, etc. are embedded ornaments (metal net, metal plate and other) laminated glass, embedded PET material laminated glass and other decorative glass.
