How to deal with high-rise glass cracking?

1, the high-rise glass is cracked. Let's first look at whether it is a man-made or natural accident. If it is found to be man-made, you can choose to call the police, do not move the broken window without authorization, to prevent any failure after moving, and there is no way to get compensation.

2. If it is caused by natural reasons such as wind and sun, you can contact the property to solve it. Glass also has a shelf life. If the glass is still within the warranty period, we can replace it for free.

3. If the glass has passed the shelf life and is not caused by personal reasons, it is best to ask the decoration company and the glass manufacturer to repair it. If the manufacturer and maintenance personnel can't arrive in time, we'd better put up a sign downstairs on that floor to remind passers-by to walk carefully and avoid being hit by the glass upstairs.

The glass in the sky is broken, so it is difficult to replace it. In order to understand the urgent need, you can also call the fire brigade to solve it.

Why does high-rise glass burst naturally?

1. Tempered glass bursts without mechanical external force, which is called self-explosion. The expansion of nickel sulfide in tempered glass is the main reason for the self-explosion of tempered glass, which is mainly brought in by impurities in glass raw materials. After a period of time, the crystal structure of some nickel sulfide particles changed from α state to β state, during which the volume of nickel sulfide particles expanded to a great extent. This volume expansion process causes the internal stress of tempered glass to be very strong, which leads to the self-explosion of tempered glass. According to national regulations, the self-explosion rate of tempered glass is 3‰.

2. Glass damage factors: careless handling, installation and maintenance of glass surfaces and edges may lead to explosion, surface corrosion, edge collapse, etc. , easy to damage tempered glass, resulting in self-explosion of tempered glass.

3. Installation factors: In the installation process, if the installation gap is small or the glass is in direct contact with the frame, the expansion coefficients of the glass and the frame are different under the irradiation of sunlight, which is easy to cause extrusion force on the edges or corners of the glass and induce the toughened glass to burst.

4. Natural factors: The design of wind pressure resistance is invalid due to typhoon and other wind disasters, which may cause the toughened glass to burst. Tempered glass is a kind of safety glass confirmed by laws and regulations, which is widely used in places with high requirements for mechanical strength and safety, such as glass doors, building curtain walls, facade windows, indoor partitions, furniture, partitions close to heat sources and places with severe cold and hot shocks.
