Glass is mainly divided into two categories: flat glass and deep-processed glass, among which there are three main types of flat glass: lead-up flat glass (slotted and non-slotted), flat-draw flat glass and float glass. Deep-processed glass is processed from flat glass and has a wide range of applications. There is now a fire-resistant glass that not only blocks the spread of flames, but even has a certain degree of thermal insulation. Next, please see what fireproof glass is classified according to, and what is the difference between fireproof glass and ordinary insulating glass.
1. What is the classification of fireproof glass?
According to the structure, fire performance and fire resistance rating of fireproof glass.
According to the structure: composite fireproof glass (FFB) and single fireproof glass (DFB);
According to fire resistance: heat-insulating fire-resistant glass (Class A) and non-heat-insulating fire-resistant glass (Class C);
According to the fire resistance rating, it is divided into 5 grades: 0.5h, 1.00h, 1.50h, 2.00h, 3.00h.
Add: heat-insulating fire-proof glass is divided into grouting fire-proof glass and composite fire-proof glass according to different production processes. Grouting fire-proof glass has good heat insulation performance, and composite fire-proof glass has good fire-proof performance.
2. What is the difference between fireproof glass and ordinary insulating glass?
First of all, fireproof glass and ordinary insulating glass are two different types of glass.
But fireproof glass can also be made into the substrate of insulating glass. Types such as: fireproof glass + airspace (6A-9A-12A) + fireproof glass, it can also be made into fireproof glass + airspace (6A-9A-12A) + tempered Glass (ordinary white glass-coated glass-Low-e).
Fireproof glass (Anti-fire Glass), whose function in fire prevention is mainly to control the spread of fire or to isolate smoke, is a measure-type fireproof material, and its fireproof effect is evaluated by fire resistance.
Insulating glass is composed of two or more pieces of glass, the middle of the glass is separated by a hollow aluminum alloy frame filled with desiccant, and the hollow part is filled with dry air or inert gas, and butyl glue is used between the aluminum alloy frame and the glass. After bonding and sealing, it is sealed with polysulfide glue or structural glue. The point-type curtain wall produced by our company utilizes the excellent optical properties of glass and integrates the essence of modern design to form a smooth, strong and strong curtain wall steel structure. Color mosaic decorative glass is made of copper bars inlaid between glass with various artistic patterns and then hollowed out.

3.1 Glass
Glass is an amorphous inorganic non-metallic material, generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw material, and a small amount of auxiliary raw materials are added. of. Its main components are silica and other oxides. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O·CaO·6SiO2, etc. The main component is silicate double salt, which is an amorphous solid with random structure. It is widely used in buildings to block wind and light, and belongs to a mixture. There are also colored glass mixed with oxides or salts of certain metals to show color, and tempered glass obtained by physical or chemical methods. Sometimes some transparent plastics (such as polymethyl methacrylate) are also called plexiglass.
3.2 Fire protection
Fire protection literally means preventing a fire from happening. In the deep processing of fabrics, it refers to a process that prevents fires from occurring. Everyone should pay attention to fire prevention, and usually learn more about fire escape to protect the safety of themselves and their families. That is to eliminate fire hazards and prevent fires from occurring.
