Application of fireproof glass in domestic buildings

Application of fireproof glass in domestic buildings

1 single piece fireproof glass

1) High strength monolithic fireproof glass

One is ordinary glass, which improves the surface stress and achieves certain fire resistance through chemical and physical tempering, that is, the single piece cesium potassium fireproof glass commonly talked about in the market; One is ordinary glass, which only improves the surface stress through physical tempering to achieve a certain fire resistance, that is, float white glass high stress fireproof glass commonly talked about in the market in recent year.

High strength monolithic fireproof glass has the advantages of light weight, low price and easy market acceptance. The disadvantage is that if the processing technology is not qualified, it is easy to have surface stress relaxation after long-term use, or lose some fire resistance due to surface and edge scratch damage; Generally, the fire resistance time shall not exceed 1.5h, and there is no heat insulation requirement; There is self explosion: the passing rate of fire resistance test is low.

High strength monolithic fireproof glass is mainly used in occasions with no heat insulation requirements and low fire resistance time requirements, such as outdoor fire-resistant windows of buildings.

2) High borosilicate fireproof glass

Borosilicate glass has become a kind of fire-proof glass with excellent performance because of its low expansion coefficient and high softening point. It was first developed and produced by Schott company in Germany. The domestic R & D and trial production began in 2018. Because of its high price, it is generally only used for testing samples of fireproof glass, which has been gradually accepted by the market in recent years. Domestic production generally adopts two processes: all electric melting cold top and all oxygen electric melting hot top. The advantage of high borosilicate fireproof glass is light weight, and the fire resistance time can generally reach 2 ~ 3H; No self explosion; The product has good stability and is not easy to be affected by frame and auxiliary materials; Low iron content, more beautiful; Excellent corrosion resistance and UV resistance; The water spraying system can replace the class a heat insulation fireproof glass system. The disadvantage is that the product production technology is immature and the qualified product rate is low; high price; No thermal insulation.

As a fire-proof glass with excellent performance and body safety, high borosilicate fire-proof glass is mainly used in fire-resistant windows, building curtain walls, smoke retaining vertical walls, daylighting roofs, fire-proof floors, etc. in particular, water spray system can replace class a heat-insulating fire-proof glass system, and can be widely used in fire-proof glass in building atrium, pedestrian street and building fire partition.

2. Composite fireproof glass

1 (inorganic) laminated composite fireproof glass

Generally, a layer of inorganic transparent fireproof glue (dry process) is sandwiched between the treated high-strength ordinary float white glass to make sandwich composite fireproof glass. The advantage is that it can be cut: it can be prepared into heat-insulating fireproof glass. The disadvantage is poor weather resistance; Unable to prepare curved surface special-shaped structure; At present, the super large plate glass can not meet the market demand; Complex process, long processing cycle and low yield. Laminated composite fireproof glass is mainly used in fireproof partition wall, daylighting roof, fireproof floor, etc.

2. Grouting fireproof glass

Generally, it is a kind of special fireproof glass with fire-resistant integrity, which is made of two to three layers of glass original sheets, sealed with special flame-retardant adhesive strips around it, and then filled with fireproof liquid in the formed cavity.

Grouting fireproof glass can be divided into organic grouting fireproof glass and inorganic grouting fireproof glass.

The advantage of organic grouting fireproof glass is that it can be prepared into thermal insulation fireproof glass. The disadvantage is poor weather resistance, easy to produce bubbles, pollution and yellowing, which belongs to the basically eliminated process.

The advantage of inorganic grouting fire-resistant glass is that this kind of fire-resistant glass is processed by inorganic materials, which can achieve more stable fire resistance and appearance quality, strong anti-aging property, no foaming, no yellowing, and heat radiation performance: strong adhesion, acid resistance and good heat resistance; It has good sound insulation and noise reduction effect. According to different thickness, the product can be made into either insulated GB class a glass or non insulated GB class C glass.

In order to improve safety, stability and save later costs, there are cases of large-scale use of inorganic grouting fireproof glass in China.

Inorganic grouting fireproof glass is mainly used in building fire partition walls, fire floors, daylighting roofs, fire doors, escape passages and escape stairs with high thermal insulation requirements and fire resistance time limit requirements.
