How to identify fireproof glass？
Glass is everywhere in life, so do you know about it? Let Xiangjie Special Shaped Glass Processing tell us how to identify fireproof glass.
The rise of high-rise residential buildings and super-high public buildings has caused the relevant departments to attach great importance to the use of safety glass and fireproof glass in high-rise buildings, and fireproof glass has become increasingly popular among builders and customers. However, in the special rectification actions for fire protection products launched in various parts of the country in recent years, the phenomenon of fireproof glass products flooding the market with fakes has been repeatedly discovered. What are the characteristics of fireproof glass, and how to identify the authenticity of fireproof glass?
Fireproof characteristics are popular. Fireproof glass is a special glass that can maintain its integrity in the prescribed fire resistance test and is widely used in the field of fire protection. According to different structural types, it can be divided into fireproof laminated glass, thin-coated fireproof glass, single-piece fireproof glass, and fireproof wired glass. According to the survey, the common single-piece fireproof glass (chemical fireproof glass) is a new type of functional material for construction, with good light transmission and fire retardant properties. After a special chemical treatment and ion exchange for more than 20 hours at high temperatures, the metallic sodium on the surface of the glass is replaced to form low-expansion silicate glass, so it has high heat resistance. When the glass is broken, tiny particles will appear, which can reduce the harm to the human body. Usually, fireproof glass is transparent like ordinary glass. After a few minutes of fire, the chemical tempered layer can prevent the spread of flames and heat transfer, and limit the fire to a small area near the fire point, playing a fire protection role. At the same time, after physical treatment, the surface of the glass forms a high-strength compressive stress, which greatly improves the impact strength.
