What causes the impact of tempered glass is not close
- 2019-09-03-

What are the reasons for the impact resistance of tempered glass, do you know? Let's analyze the reasons!

  1. The heating and cooling process does not meet the requirements. The heating temperature is too low, the heating time is too short, and the air volume of the cooling air pressure is small and the time is short. It has poor impact.

  2. Due to scratches on the surface of the glass, its appearance stress is relatively low during the manufacturing process, which leads to a decrease in strength and a reduction in impact resistance.

  3. Before the tempering treatment, the glass edge was not treated well, and there were some small cracks, which caused it to be broken due to the impact and not released in time.

  4. Due to the different temperatures received on the surface of the glass during heating or cooling, the stress formed on the surface is not uniform, reducing its strength.

Under normal circumstances, if the stress of the tempered glass is not uniform, it will increase its self-detonation rate, causing it to abnormally detonate. The reason for its uneven stress is due to the uneven distribution of local stress and the deviation of the thickness of the tension layer, which has a certain effect on the quality of the glass itself. Uneven stress will reduce the strength of the glass. Through the above, we can understand that the uneven stress of tempered glass will lead to its self-detonation rate. Therefore, in order to reduce the self-detonation rate, we need to ensure that the stress distribution of tempered glass is uniform.

The above-mentioned points are the reasons for the unqualified impact resistance of tempered glass, so it is necessary to prevent the above situation in the manufacture of tempered glass.

The company is a comprehensive enterprise integrating glass research and development, manufacturing, sales, design and construction. It currently has an advanced technical service team, a mature market channel, and a good corporate reputation. With its integrity, strength, product quality and service, it stands out from the fiercely competitive market and develops steadily.
