Development of building fireproof glass

In case of building fire, fireproof glass has the special function of controlling fire extension and smoke separation, which can minimize the loss, and plays an important role in ensuring the safety of citizens' lives and property.

The production and use of building fire-proof glass originated in Britain in the 1970s, and then it was also widely produced and used in European and American countries. 80% of fireproof glass in Europe needs thermal insulation fireproof glass, with an annual market demand of about 600000 ~ 800000 M ³。 China's fireproof glass began to be produced in the 1980s. It was first used in the observation window on the fireproof door. After years of development: Now a complete product system of thermal and non thermal insulation fireproof glass, single-chip and composite fireproof glass has been formed, which can be widely used in different construction market categories. Functional requirements for building fireproof glass

1. Fire resistance integrity

Under the standard fire resistance test conditions, when one side of the glass component is exposed to fire, it can prevent the penetration of flame and hot gas or the appearance of flame on the back fire surface within a certain time

2. Fire resistance and thermal insulation

Under the standard fire resistance test conditions, when one side of the glass component is exposed to fire, the temperature of the back fire surface can not exceed the specified value within a certain time.

3. Fire resistance time

Under the standard fire resistance test conditions, the period from the action of fire to the loss of integrity or thermal insulation requirements of glass components.

4. Code of practice for building fireproof glass

The performance specifications of building fire-proof glass mainly include the specifications of domestic building fire-proof glass and the development direction of fire-proof glass

Compared with the general monolithic fireproof glass, the borosilicate fireproof glass in the monolithic fireproof glass has excellent fireproof function, but the price is higher. With the continuous improvement of production skills and the gradual decline of production cost of borosilicate fireproof glass, its market share will be larger and larger.

Inorganic grouting fire-proof glass in composite fire-proof glass will be the main development trend of building fire-proof glass in the next step because of its good fire-proof and thermal insulation function and wide application scale. Therefore, we should focus on developing and improving the formula of fire-proof slurry to further improve the weather resistance of inorganic grouting fire-proof glass products.

In the composite fireproof glass, the development experiment of replacing the general float glass with borosilicate monolithic fireproof glass is carried out to further improve the function and lightweight of the composite fireproof glass.

In view of the use of composite fire-proof glass in building partitions, super large standard quantitative thermal insulation composite fire-proof glass should be developed and produced. According to the different needs of construction, special-shaped fireproof glass is developed and produced. Develop the skill development and market of body colored fireproof glass, and promote the subsequent deep processing development of diversified fireproof glass meeting the energy-saving requirements.
