What should be paid attention to when purchasing and using tempered glass?



Tempered glass, as a type of deeply processed glass, is made from ordinary float glass as the original sheet and further processed, which significantly improves its safety performance，Glass product   .

At present, China implements CCC mandatory certification management for safety glass. Safety glass refers to various types of safety glass used in automobiles, buildings, and railway vehicles. Tempered glass is a vital part of safety glass. It is clearly pointed out in the Regulations on the Administration of Building Safety Glass (FGYX [2003] No. 2116) that building safety glass refers to "tempered glass, laminated glass and other glass products made of tempered glass or laminated glass, such as safety insulating glass, which meet the current national standards". It is clearly pointed out in JGJ 113-2009 Technical Specification for Application of Architectural Glass that safety glass must be used in framed glass, indoor partition, shower partition, bathtub partition and other places of fixed doors and french window of movable doors.



Tempered glass is made from ordinary float glass as the original sheet and further processed. Compared with ordinary float glass, its performance and safety performance are significantly improved. Its impact strength is 4-5 times higher than ordinary float glass, and its bending strength is 5 times higher than ordinary float glass. It has good thermal stability and is 2-3 times higher than ordinary float glass. When qualified tempered glass is subjected to strong impact damage, the fragments are dispersed into small particles without sharp edges and corners, which can effectively avoid serious personal injury. This is also the main reason why tempered glass is widely used.



At present, there are various kinds of deeply processed glass in the market, such as tempered glass, Frosted glass, coated glass, coated glass, color changing glass, colored glass, etc. Consumers need to pay attention to the following issues when choosing and using:



When consumers purchase tempered glass, they must provide relevant testing reports or provide written explanations on the type of glass from the seller. After quality issues occur with tempered glass, some sellers may change their claims that the products they sell are reinforced glass rather than tempered glass, causing unnecessary trouble.



When users purchase glass products, they can distinguish the quality of glass from its appearance. When purchasing glass products, you can observe through the glass in a well lit area to see if there are defects such as bubbles, inclusions, pits, and scratches on the surface of the glass.



3. When purchasing glass, pay attention to measuring its thickness, as some manufacturers may cut corners in these areas.



4. For users who purchase glass in large quantities, especially when purchasing safety glass products, the seller must present relevant safety certification certificates and quality assurance certificates.



5. Due to the hidden danger of self explosion in tempered glass (the probability of self explosion in most manufacturers' products is 3/1000), consumers should try to avoid hard impact on the edges and corners of tempered glass when installing and using it, and maintain elastic contact. The hard adhesive strips around the installation of glass doors and windows are also
