The main reasons for the explosion of glass shower enclosures are as follows:

Reasons for explosion
Quality problems of tempered glass:
Impurities and bubbles: Nickel sulfide crystals, impurities or bubbles may remain in tempered glass during the production process. These impurities or crystals may expand in volume when affected by temperature or time, causing tiny cracks inside the glass, which in turn affects the stress balance of the tempered glass and causes explosion.
Thickness does not meet the standard: In order to reduce costs, some shower room manufacturers may use tempered glass whose thickness does not meet the specified requirements, which is more likely to explode.
Improper installation:
Stress concentration: During the installation process, if the surface and edges of the glass are scratched, cracked, or damaged, or if the tilt is too large during installation, or the shape of the glass is artificially changed, etc., it may cause stress concentration, which may cause explosion.
Cutting: Cutting the glass after tempering is also very likely to cause the glass to explode.
Improper use and maintenance:
Large temperature difference: The interior of the shower room is a relatively closed space. The temperature is high when taking a bath. The accumulation of high temperature and high pressure to a certain extent will form pressure on the glass. If the glass quality is poor or the temperature difference is large in winter, it is easy to cause the glass to burst.
Sharp object impact: Although tempered glass has high strength, it is afraid of scratches and impacts from sharp objects. The contact area of ​​sharp objects is small, and the pressure on the glass is large, which can easily cause the glass to crack.

Preventive measures
Purchase high-quality tempered glass:
Check the certification: Choose tempered glass with the 3C certification mark to ensure product quality.
Observe the appearance: Wear polarized sunglasses to observe the glass, and it should show colored stripes; the naked eye should have blue spots from the side.
Proper installation:
Professional installation: Try to ask the manufacturer to provide professional personnel to install on site to ensure that the glass will not be damaged during the installation process.
Supervision process: During the installation process, supervise the construction personnel not to cut or process the glass unnecessarily.
Protect the glass corners:
Regular inspection: The edges around the tempered glass are relatively weak and prone to cracks. Regularly check whether there are cracks on the glass corners and repair them in time.
Avoid collisions: In daily life, avoid heavy or sharp objects hitting the corners of the glass.
Paste explosion-proof film:
Choose qualified explosion-proof film: Choose explosion-proof film certified by the International Window Film Association and qualified to produce safety film, and paste it on the glass to prevent fragments from splashing and injuring people when it explodes.
Precautions for use:
Slowly increase the water temperature: When taking a bath, do not suddenly use hot water that is too hot to reduce the risk of uneven heating of the glass.
Open and close slowly: When using the shower door, open and close it slowly to avoid excessive force that may damage the glass.
Choose laminated glass:
Improve safety: If conditions permit, you can choose to replace ordinary tempered glass with tempered laminated glass. Even if the laminated glass explodes, its film can stick the fragments together to prevent splashing and injuring people.

Through the above measures, the risk of self-explosion of the glass shower enclosure can be effectively reduced and the safety of use can be improved.
