How can I reduce the self-explosion rate of tempered glass?

    In order to effectively reduce the self-explosion rate of tempered glass, it is necessary to take comprehensive measures from many aspects such as material selection, process treatment, installation specifications and alternatives, and the specific measures are as follows:

1. Preferred glass materials

Use high-quality original film
    Choose large brands of glass such as CSG, Taiwan Glass, Xinyi, etc., which have low impurity content (such as less nickel sulfide stones), which can significantly reduce the risk of self-explosion

The use of ultra-clear glass
    Ultra-clear glass has a self-explosion rate of only about 0.01% (0.3% for ordinary tempered glass) due to the extremely low content of impurities such as iron and nickel
2. Special process treatment

Homogenization treatment (hot soak treatment)
    Heats the tempered glass to 280-300 °C and keeps it warm for 2-4 hours, which promotes the early bursting of the glass containing nickel sulfide impurities, which can reduce the self-explosion rate to Less than 1 in 10,000
Control the tempering process
    Ensure uniform stress distribution and avoid local stress concentrations (especially for curved glass)
    Low-E coated glass requires forced convection technology to reduce thermal stress asymmetry

3. Standardize installation and processing

Installation details
    Glass cushions must be placed between the glass and the profile to avoid direct contact with the aluminum to generate extrusion stress
    Use neutral window and door caulk instead of cement or blowing agent to prevent profile deformation

Processing requirements
    The glass edge is finely ground to remove defects such as micro-cracks and edge bursts
    The drilling part needs to be chamfered to reduce the stress weak point

4. Alternatives and design optimization

Laminated glass application
    Laminated insulating glass is recommended for oversized glass , which can be bonded by film even if the self-detonating fragments are used to prevent falling and injuring people
Reduce the use of large slabs and
    control the ratio of single glass area to thickness to avoid the risk of self-explosion due to stress accumulation
5. Mindset adjustment and probability cognition

With a self-explosion rate of only 0.3% for ordinary tempered glass , the risk can be further reduced without undue concern

Key data reference:

Self-explosion rate after homogenization: ≤0.01%
Self-explosion rate of ultra-clear glass: ≈0.01%

Self-explosion rate of untreated ordinary tempered glass: 0.3%-3%

Through material upgrading, process optimization and standardized construction, the hidden danger of self-explosion can be systematically avoided to ensure both safety and aesthetics.
