In recent years, tempered glass has become a popular choice for home and business owners because of its durability and safety. However, many people have reported unexpected and sudden shattering of their tempered glass, which has raised concerns about the safety of this popular material.

 

After thorough research, experts have discovered that several factors can contribute to tempered glass shattering unexpectedly.

 

The Main Reasons Why Tempered Glass Shatters

 

1. Internal factors‌:

 

--1..1. Nickel sulfide impurities‌:

The nickel sulfide impurities contained in tempered glass will undergo a phase change when the temperature changes, causing volume expansion, thereby generating internal stress, eventually causing the glass to break.

 

--1.2. Bubbles and impurities‌:

Defects such as bubbles, sand, and debris in the glass may gradually expand during long-term use, causing the glass to break.

 

--1.3. Quality issues‌:

Poor raw material quality, improper production process control, etc. will cause tempered glass to be fragile during use.

 

2. External factors‌:

 

--2.1 Installation issues‌:

If the tempered glass is not the right size, is installed too tightly, or does not meet specifications, it may have an impact on its internal stresses, causing the glass to break.

 

--2.2. Usage environment‌:

External factors such as excessive load, collision or improper gap setting may also cause tempered glass to break, especially under extreme temperature changes.

 

--2.3. Design and construction‌:

Improper design and construction can also cause tempered glass to self-explode. For example, it can easily become brittle when the stress structure changes.

 

3. stress concentration‌

 

--3.1. Processing defects:

scratches, cracks, deep edges and other defects on the glass surface caused by improper processing or operation, which can easily cause stress concentration or cause the tempered glass to self-explode.

 

--3.2. Uneven stress distribution‌:

When the glass is heated or cooled, the temperature gradient generated along the thickness direction of the glass is uneven and asymmetrical, causing the tempered product to have a tendency to self-explode.

Tips to Reduce the Shatter of Tempered Glass

 

1. Choose high-quality raw materials‌:

Ensure the quality of raw materials and reduce the risk of self-explosion caused by raw material quality problems.

 

2. Strictly control the production process‌:

Strictly control the process flow during the production process to reduce defects such as bubbles and impurities.

 

3. Reasonable design and installation‌:

Ensure that the installation size of tempered glass is appropriate and in compliance with specifications to reduce the risk of self-explosion caused by installation problems.

 

4. Regular maintenance inspection‌:

Regularly maintain and inspect tempered glass during use to discover and deal with potential defects and problems in a timely manner.

 

5. Use laminated glass‌:

If you need to use oversized glass, it is recommended to choose laminated glass. Even if the laminated glass is broken, the fragments will be stuck together by the film and will not fall and hurt anyone‌

 

6‌. Use ultra-white glass‌:

Ultra-white glass has fewer impurities than ordinary glass and has a lower chance of self-explosion. The self-explosion probability of ultra-white glass is only one-third of that of ordinary glass‌

 

7. Pay attention to the installation details‌:

When installing tempered glass, make sure there are glass spacers between the large glass and the profile to avoid direct contact of the glass with the profile. At the same time, use door and window caulking agent instead of cement or foaming agent to prevent self-explosion caused by settlement and deformation‌

 

‌8. Carry out secondary heating and detonation treatment‌:

Through heat dipping treatment (homogenization treatment), heating the tempered glass to a constant temperature of about 290 degrees for 2 hours can reduce the self-explosion of glass with impurities‌

 

9. Paste polyester film or explosion-proof film‌:

Paste high-performance polyester film or explosion-proof film on the glass. Even if the glass self-explodes, it can still stick to the fragments and protect personnel safety‌

 

10. Packaging and transportation‌:

Use wooden boxes or containers for transportation, and each piece of tempered glass should be packed in a silica gel bag or paper shell to ensure that the tempered glass is not damaged during transportation and storage‌

Through the above methods, the self-explosion rate of tempered glass can be effectively reduced and the safety of use can be ensured.

 

Despite the risks associated with tempered glass, it remains a popular choice for many homeowners and businesses due to its affordability and versatility. However, sellers and manufacturers are under pressure to address consumer concerns and improve safety standards to reduce the risk of accidents.

 

The demand for tempered glass continues to grow, driven by the increasing popularity of modern architectural styles and the need for durable and safe building materials. This has resulted in a highly competitive market, with companies vying for a share of the lucrative industry.

 

To stay competitive, many tempered glass manufacturers are investing heavily in research and development to improve the quality of their products and reduce the risk of shattering. At the same time, innovative companies are exploring new ways to use tempered glass, including in the automotive, aerospace, and renewable energy sectors.

 

In conclusion, the unexpected shattering of tempered glass has raised concerns about its safety, but proactive measures can be taken to prevent accidents. As the demand for tempered glass continues to grow, manufacturers are under pressure to improve safety standards and innovate new applications for this versatile material. The tempered glass market is set to remain highly competitive, with new opportunities for expansion and growth in emerging economies.
