Introduce the characteristics and functions of fireproof glass. Introduce the definition of fireproof glass. Fireproof glass is mainly used to control the spread of fire or smoke. It is a kind of fireproof material with fireproof effect. Conduct an evaluation. It is a special glass that has been specially processed and treated to maintain its integrity and thermal insulation in specified fire tests. The original glass of fireproof glass can be made of float flat glass, tempered glass, composite fireproof glass can also be made of single piece fireproof glass.
Features and functions of fireproof glass:
1 superior fire resistance performance
The single piece of fireproof glass can survive for more than 90 minutes under the flame impact of up to 1000 °C, thus gaining valuable time for people to escape and disaster relief work.
2 High strength performace
The single-piece fire-resistant glass not only has excellent fire resistance, but also has a high strength and outstanding hardness. At the same glass thickness, the strength of a single piece of fire resistant glass is 6-12 times that of float glass; it is 2-3 times that of tempered glass.
3 safety (safety performace)
After the single piece of fireproof glass is broken, the pieces are obtuse and the pieces are smaller than the pieces of tempered glass, so even if they are damaged, they will not cause harm to the human body.
4 high weatherability (Weatherability)
Compared with traditional grouting or composite sandwich fireproof glass, single-piece fireproof glass has the highest characteristics except high strength, and it has no influence on the appearance and service performance under the long-term exposure of ultraviolet light. It can be transparent and bright for a long time.
5 workability is good (Workability)
The single piece of fireproof glass can be used in a single piece, or can be processed into fireproof laminated glass, fireproof insulating glass, point fireproof curtain wall glass, fireproof coated glass, etc. as needed.
The characteristics and role of fireproof glass
Since the mass production of single-chip fireproof glass in China, fireproof glass has been widely used, but there are several points to be aware of when using it:
1. Before selecting fireproof glass, it is necessary to know the specific fire protection requirements of fireproof components composed of fireproof glass, whether it is fireproof, heat insulation or smoke insulation, fire endurance requirements, etc.
2. Single-piece and composite-filled fire-resistant glass cannot be cut with a glass cutter like ordinary flat glass, and must be cut to length, but composite (dry) fire-resistant glass can meet the requirements of cutting.
3. When the fireproof glass is used to form the fireproof component, in addition to considering the fireproof durability of the glass, the support structure and each element must also meet the fire resistance requirements.
The monolithic cesium-potassium fire-retardant glass is subjected to special chemical treatment for more than 20 hours of ion exchange at a high temperature, replacing the metal sodium on the surface of the glass to form a chemical tempering stress; and at the same time, a high-strength compressive stress is formed on the surface of the glass after physical treatment. , greatly improve the impact strength, when the glass breaks, it shows a state of tiny particles, reducing damage to the human body! The strength of a single piece of yttrium-potassium fire-resistant glass is 6-12 times that of ordinary glass and 1.5-3 times that of tempered glass!
China's building code requires that all products installed on the partitions with fire protection requirements should be sampled by the provincial fire brigade to the national designated fireproof material testing center (ie, the fireproof building materials quality supervision and inspection center of Sichuan and Tianjin). One) to carry out the test, must meet the requirements of the specification, and obtain the inspection report issued by these institutions before they can be sold!
The fire resistance test of single-piece cesium-potassium fire-retardant glass is carried out according to the current national standards, and has been tested to meet the specifications of the People's Republic of China National Standard GB15763.1-2001 "Safety Glass Fireproof Glass for Construction".
The advantage of a single piece of yttrium-potassium fire-resistant glass is that it has a lesser relationship with the temperature at which it can work, but it has the ability to withstand the rapid changes in heat shock and temperature, depending on the specific heat capacity of the glass (which affects the rate at which the temperature rises) , thermal conductivity (heat rate and distribution through the glass) and thermal expansion rate, while a single piece of cesium-potassium fire-resistant glass can withstand quenching treatment from 300 ° C to cold water!
The thermal conductivity of monocrystalline yttrium-potassium fire-resistant glass is 1.13W/M°C
The thermal expansion coefficient of a single piece of yttrium-potassium fire-resistant glass is: (8.5-9.5)*10-6/°C, which is the same as the original glass.
Water resistance meets: ISO719-HGB, ISO720-HGA standard
Acid resistance meets: ISO1776 standard
Alkali resistance meets: ISO695-A standard
Compared with traditional grouting fireproof glass, single-piece strontium-potassium fire-resistant glass has the highest characteristics of high weather resistance in addition to high strength and easy installation! In addition to the bubbles that are prone to occur during the manufacturing process, the chemically-filled fire-resistant glass quickly becomes milky white under the action of ultraviolet radiation and flame, and loses the basic function of glass transparency, so that it is impossible to observe the fire situation! The single piece of yttrium-potassium fire-proof glass remains transparent under the action of ultraviolet light and flame without any change!
