What Is The Use Of Fireproof Glass What Is Laminated Composite Fireproof Glass

1. What is the purpose of fireproof glass.

Fire-resistant glass is a new type of building functional material with good light transmission and fire-retardant properties. It has high heat resistance, light specific gravity, high light transmittance, no yellowing, no bubbles and other unique characteristics. The fire-resistant glass with good performance has good fire-retardant and flame-retardant properties even at high temperatures above 1000 ℃.

The following are the functions and characteristics of fireproof glass:

Composite fire-resistant glass (or fire-resistant laminated glass) is made by bonding two or more single-layer flat glass sheets together with an intumescent flame-retardant cement; the perfusion type fire-resistant glass is made of two or more sheets The surroundings of two or more single-layer flat glass are sealed with frame strips, and then filled with fire-resistant liquid from the pouring port, which is cemented and sealed; at room temperature and at the beginning of a fire, the composite fire-resistant glass is the same as ordinary flat glass It has light transmittance and decorative properties; after a fire, as the fire spreads and the fire temperature rises, the composite fireproof glass fireproof interlayer is heated and expands and foams, forming a thick fireproof insulation layer, which plays a role in fire insulation and fire protection Separating effect. However, composite fireproof glass generally has tiny bubbles, cold resistance, poor light transmission and other problems, which affect its use effect.

Thin-coated fire-resistant glass is sprayed with a fire-resistant transparent liquid on the surface of a single-layer or multi-layer flat glass substrate, and then dried and cured to make fire-resistant glass. When the thin-coated fire-resistant glass encounters a fire, the fire protection layer is heated to expand, forming a dense fire protection The protective layer protects the substrate glass and prevents the spread of fire.

2. What is laminated composite fireproof glass

 Laminated composite fireproof glass is made by compounding the single-layer flat glass purchased or above with an intumescent flame retardant adhesive (commonly known as fireproof gel). According to different production methods, sandwich composite fireproof glass is indeed divided into It is perfusion type (wet method or grouting method) and sandwich type (dry method). Sandwich type composite fireproof glass is made by bonding two or more single-layer flat glass sheets with intumescent flame retardant adhesives. Or it is composed of a piece of glass and agricultural production system materials; the perfusion type fireproof glass is sealed with frame strips around two or more single-layer flat glass, and then filled with fireproof liquid from the perfusion port, and then glued , Made of sealing.

At room temperature and in the early stage of a fire, laminated composite fireproof glass has the same light transmission and decorative properties as ordinary flat glass; after a fire, as the fire spreads and expands, the temperature rises, and the fireproof gel in the glass decomposes. A foam-like thermal insulation layer is formed to make the material opaque, prevent the spread of flame and heat transfer, and limit the fire to a small area near the ignition point, which plays a role of fire insulation and fire separation. The performance of laminated composite fireproof glass mainly depends on The performance of fireproof adhesives. However, generally laminated composite fireproof glass has problems such as tiny bubbles, cold resistance, and poor light transmission, which have a certain impact on the use effect. Laminated fireproof glass can also be embossed glass, stained glass and colored Colored fireproof glass is made of gel, etc., which plays a role of decoration and fire prevention.
