[China Glass Net] The thickness deviation of the dry laminated glass should not exceed the sum of the allowable deviation of the slabs constituting the laminated glass and the allowable deviation of the intermediate layer. When the total thickness of the intermediate layer is less than 2 mm, the allowable deviation is not considered. When the total thickness of the intermediate layer is greater than 2 mm, the allowable deviation is ±0.2 MM.
With the progress of society and the improvement of people's living standards, people are no longer satisfied with the use of ordinary glass, and the deep processing industry of glass is increasingly developed.
The glass secondary product, that is, the deep-processed glass, is made of flat glass (float glass, ordinary flat glass, flat glass, rolled glass) which is formed at one time, and is made of different processing methods according to the use requirements. Glass products with specific functions. A commonly used laminated glass article material is float glass.
The laminated safety glass is made of a plastic material such as a polyvinyl butyral (PVB) interlayer film, a polycarbonate plate, a polyurethane plate or an acrylate plate between two or more layers of glass, and is processed by high temperature and high pressure. A common intermediate material for laminated glass products is polyvinyl butyral (PVB) film.
PVB film has good adhesion, toughness and elasticity. When the laminated glass is struck by external force, this film will absorb a lot of energy, and the glass fragments will adhere to the PVB interlayer film, and the glass fragments will not fly. Reduce possible damage to a lower level. Laminated glass has good security, noise reduction, solar control and UV protection. If necessary, ordinary float glass, tempered glass, LOW-E glass, etc. can be used as the original sheet of the laminated glass, so that the laminated glass has different properties.
Compared to glass products, laminated safety glass has the following main functions:
(1) Improve the strength of the glass and enhance the safety of the glass.
(2) Change the shape of the flat glass.
(3) Treatment of the glass surface.
Glass surface treatment consists of two aspects:
A) enriching the surface of the glass, that is, using physical or chemical methods to create different patterns and patterns on the surface of the glass;
B) is to apply a coating treatment to the surface of the glass.
Laminated glass is produced in both dry (Class A) and wet (B) forms. Currently, (A) PVB membranes are the mainstream for dry production of laminated glass.
Today's glass deep processing business is characterized by fixed frequency, variety, short cycle and fast delivery. Such a production mode has a relatively higher requirement for glass processing equipment. Glass deep processing equipment must be able to meet the needs of mixed production with high flexibility.
