How to prevent the self-explosion of tempered glass sheet

How to prevent the self-explosion of tempered glass sheet?

The characteristics of tempered glass sheet determine that its self-explosion is unavoidable, and the time and conditions of self-explosion cannot be estimated. Therefore, in order to prevent the harm caused by the self-explosion of tempered glass sheet, some measures or methods are often taken in the process of glass processing and installation. , to reduce the loss caused by the self-explosion of tempered glass sheet.

01

Hot dip treatment (homogenization treatment)

The tempered glass sheet is placed in a hot dip furnace for heating, heat preservation and cooling treatment, so that the nickel sulfide in the tempered glass sheet can reach a stable state, and the stress inside the glass can be balanced, so as to reduce the self-explosion rate.

02

Laminated glass

The PVB interlayer film is sandwiched between the glass, and it is made by high temperature and high pressure processing. Because the toughness of the PVB film is very good, when the laminated glass is broken by external force, it can absorb a large amount of impact energy and quickly attenuate it, so it is difficult for the laminated glass to break down and maintain excellent integrity. This enables the building with laminated glass to remain in the door and window frame even if the glass is broken in the event of explosion, wind disaster, earthquake, etc., protecting people inside and outside the building from the hazard of flying glass fragments. It is also difficult for other foreign objects to cause damage to the interior.

03

Film glass

Laminate high-performance polyester film on glass. Polyester film is commonly known as safety explosion-proof film. When the glass is broken due to various reasons, it can stick to the glass fragments to prevent splashing, protect the people inside and outside the building from the hazard of the splashing glass fragments, and it is difficult for wind, rain and other foreign objects to cause damage to the interior. . The safety explosion-proof film can be connected with the frame edge system together with the organic glue to form a glass film protection system to prevent falling.

In a word, modern glass production technology cannot completely eliminate the existence of nickel sulfide impurities. Under the action of multiple reasons, tempered glass sheet is prone to self-explosion.

No piece of glass is perfect, and we cannot require every piece of glass to be perfect. As long as we try to buy tempered glass sheet with guaranteed quality when choosing, the chance of self-explosion is very small.

The closer to the sky, the easier it is to breathe, and the sun gathers from all directions, illuminating a precious little world. The sun room is deliberately and transparently surrounded, and it becomes a habitat for people to settle and think. And such a world, only after careful and safe creation, can it truly give people comfort.
