What are the characteristics of fireproof glass and tempered glass? A1. Safety of tempered glass. When the glass is damaged by external force, the fragments will form small obtuse angular particles similar to honeycomb, which is not easy to cause serious harm to human body. The impact strength of tempered glass with high strength and the same thickness is 3 ~ 5 times that of ordinary glass, and the bending strength is 3 ~ 5 times that of ordinary glass. Thermal stability: tempered glass has good thermal stability. It can withstand three times the temperature difference of ordinary glass and can withstand the temperature difference change of 300 ℃.

2. Fireproof glass has fire resistance, which should be the primary feature in the function of fireproof glass. A single piece of fireproof glass can not burst for more than 90 minutes under the impact of flame up to 1000 ℃, so as to win valuable time for people's escape and disaster relief.

3. Fireproof glass has high weather resistance. Compared with traditional grouting or laminated fireproof glass, one of the main characteristics of fireproof glass is high weather resistance. The so-called high weather resistance means that there is no change affecting the appearance and use performance under long-term ultraviolet irradiation, which can help to keep transparent and bright in the past.

4. The fire-proof glass is safe. The fragments of a single piece of fire-proof glass are in an obtuse angle state, and the fragments are smaller than those of tempered glass. Even if they are damaged, they will not cause harm to human body.
