Let’s to an explanation on the self-explosion of tempered glass, why your glass broke on the normal situation.

As an irreplaceable product, tempered glass can be seen everywhere in daily life, such as glass table tops, glass doors, shower room glass, glass handrails, and decorative panels.

During use, due to some special reasons, under normal conditions of use, and there is no visible external impact, it will break or explode.

Let’s learn the reasons for shattering or bursting are as follows:

1. Reasons for the original float tempered glass

1.1 The expansion of nickel sulfide inside the tempered glass is the main cause of the spontaneous explosion of the tempered glass.

This substance is mainly brought in by impurities in the glass raw material.

This volume expansion process triggers the strong internal stress of the tempered glass and causes the tempered glass to explode.

Normally, the self-explosion rate of tempered glass ranges from 3% to 0.3%, how to buy the less than 0.3% self-explosion tempered glass,

1.2 Excessive tempering, uneven stress of tempered glass, low quality of glass edge processing, and other external factors in the production

the process will make tempered glass with internal stones more likely to explode.

2. Improper design, installation, or use

2.1 Such as the use of oversized tempered glass, the stress concentration of the glass caused by improper installation.

the use of glass components made of multiple pieces of tempered glass or tempered glass and other glass.

2.2. And the structure or use environment of the structure or use environment makes the tempered glass suffer from poor heat exchange for a long time.

But it frequently undergoes large temperature differences, alternating hot and cold, and so on.

The above situation shows that removing the design, installation, or improper use, and other factors.

The root cause of the self-explosion of tempered glass is determined by its own inherent characteristics, so the self-explosion of tempered

glass in a non-impact state cannot be completely avoided.

In order to reduce the hazards and losses caused by the self-explosion of tempered glass

The following measures can be taken to reduce the breaking or bursting of the above-mentioned tempered glass in the non-impact state.

a) Use original tablets with fewer nickel sulfide stones, particulate impurities, and air bubbles.

Use high-quality processing-grade flat glass original sheets; moderate tempering to avoid excessive glass tempering stress and ensure uniform surface stress as much as possible; improve the quality of edge processing;

The tempered glass according to the requirements of Chinese standard GB15763.4-2009 Appendix A Perform secondary heat treatment(usually called detonation, homogenization, or hot dipping);

Scan the product with reference to GB/T30020-2013 “Glass Defect Detection Method_Photoelastic Scanning Method” before the tempered glass leaves the factory to analyze the stress concentration points

Types of defects in the category, and take corresponding measures for products with potential self-explosion.

Then according to different country’s quality standards, such as CE EN12150, SGCC ANSIZ.97 2017, etc.

b) Design and use a tempered glass of appropriate size, and ensure the accuracy of the processing;

Ensure the quality of installation, avoid deformation of the tempered glass during the installation process; rationally design and use glass components with tempered glass to reduce thermal expansion and contraction The effect of thermal stress.

It is also very important to choose the right glass processor and manufacturer.

Buy high-quality glass products at a reasonable price, instead of just caring about the price and not paying attention to the problem of the product quality.

I believe that every customer is not willing to have a big risky glass self-explosion that he sold.
