Notice on purchase of laminated glass



Laminated glass is composed of two or more pieces of float glass, one or more layers of PVB, pressurized and heated by high-pressure kiln and other equipment. Due to the excellent impact resistance and bonding performance of this bonding material, when the glass is subjected to impact fracture, due to the bonding effect of the PVB film sandwiched between its two ordinary glass pieces, sharp fragments will not be generated to harm people like ordinary glass after fragmentation. At the same time, the sound insulation and sunlight control properties of its PVB intermediate film make it a new type of building material with energy-saving and environmental protection functions.

The use of laminated glass can not only isolate the 1000~2000 Hz coincidence noise that can penetrate ordinary glass, but also block more than 99% of the ultraviolet light and absorb the heat in the infrared spectrum，Glass product    .

Introduction to laminated glass, purchasing skills and installation knowledge. People are more and more fond of laminated glass. Glass is widely used, but how much do we know about laminated glass and what safety precautions we should pay when installing it? This article summarizes several points on this topic, and let's follow the furniture drawing website to learn about it!
 
 
 
Laminated glass
 
 
 
1、 Introduction to laminated glass
 
 
 
Laminated glass is a composite glass product made of two or more pieces of glass with one or more layers of organic polymer intermediate film sandwiched between them. After special high-temperature preloading (or vacuum pumping) and high-temperature and high-pressure processing, the glass and the intermediate film are permanently bonded together.
 
Common laminated glass intermediate films include PVB, SGP, EVA, PU, etc. In addition, there are some special ones, such as laminated glass with colored intermediate film, laminated glass with SGX type printing intermediate film, and laminated glass with XIR type LOW-E intermediate film. Embedded decorative parts (metal mesh, metal plate, etc.) laminated glass, embedded PET material laminated glass and other decorative and functional laminated glass.
 
 
 
2、 Shopping tips
 
 
 
1. Folding, looking at signs, checking certificates
 
 
 
Since the safety glass product certification was carried out in 2003, most of the construction laminated glass manufacturing enterprises in China have passed the product certification. Enterprises must screen or paste the 3C mark on the product body they sell, or add the 3C mark on its minimum outer package and attached documents (such as certificate of conformity). When purchasing products, the first step is to check if there is a 3C mark, and check through the internet whether the purchased products are within the scope of the company's mandatory certification capabilities and whether the certification certificate is valid based on enterprise information, factory number, or product certification certificate.
 
 
 
2. Folding to check appearance and quality
 
 
 
Check the appearance quality of the product, and the laminated glass shall be free of cracks and degumming; The length or width of the bursting edge should not exceed the thickness of the glass; Scratches and abrasions should not affect the use; The defects such as bubbles, impurities, or other visible opaque substances in the intermediate layer should not exceed the requirements of GB/T 15763.3 standard.
 
 
 
In the process of use, external force impact shall be avoided as far as possible, especially for the tempered laminated glass. When cleaning glass, be careful not to scratch, scratch, or abrade the surface of the glass to avoid affecting its optical performance, safety performance, and aesthetics. Laminated glass is installed
