Characteristics and application of building fireproof materials

Characteristics and application of building fire protection materials

1. Flame retardant and fire protection of objects

Combustion is a violent oxidation reaction with both exothermic and luminous effects. Heat release, luminescence, and generation of new substances are the three characteristics of combustion phenomena. Combustibles, combustion-supporting substances and ignition sources are often referred to as the three elements of combustion.

2. Flame retardants There are many types of flame retardants that have been industrialized, mainly designed for the flame retardant of polymer materials. According to the method of use, flame retardants can be divided into two types: additive flame retardants and reactive flame retardants.

3.Fire Retardant Coating

Fire retardant coating refers to the coating on the surface of the object, which can reduce the flammability of the surface of the object and prevent the spread of heat to the object, thereby preventing the object from heating up rapidly and retarding the spread of fire , Substances that improve the fire resistance limit of objects. Fire retardant coatings are mainly composed of two parts: base material and fire retardant additives.

4. Water-based fire retardant liquid

According to the use object of water-based fire-retardant liquid, it can be divided into water-based fire-retardant liquid for wood fire-retardant treatment, water-based fire-retardant liquid for fabric fire-retardant treatment and There are three types of water-based fire retardant liquids for flame retardant treatment of cardboard.

5. Fire blocking material

Fire blocking material is specially used to block various penetrations in buildings, such as cables, air pipes, oil pipes, air pipes, etc. passing through walls, floors, etc. Openings and cable trays, etc., are fireproof and heat-insulating materials that are easy to replace. According to the composition, shape and performance characteristics of fire blocking materials, they can be divided into three categories: organic fire blocking materials using organic polymer materials as adhesives, inorganic fire blocking materials using faster than cement as cementing materials, and flame retardant materials using A fireproof bag formed by a fabric wrap.

6. Fireproof glass

At present, there are many kinds of fireproof glass for building produced at home and abroad, which can be mainly divided into two categories, namely non-insulation fireproof glass and heat insulation fireproof glass. Non-insulated fire-resistant glass is also called refractory glass. This kind of fireproof glass is of single-piece structure, which can be divided into three categories: wired glass, heat-resistant glass and glass-ceramic. Thermal insulation fireproof glass is a sandwich or multi-layer structure, so it is also called composite fireproof glass. This type of fireproof glass is also available in two product forms, multi-layer bonded and grouted.

7. Fireproof sheet

There are many kinds of fireproof boards, mainly fiber reinforced calcium silicate board, refractory gypsum board, fiber reinforced cement slab (TK board), GRC board, Taibo board, GY board board, flame retardant plywood, flame-retardant aluminum-plastic building decorative board, mineral wool fireproof sound-absorbing board, expanded perlite decorative sound-absorbing board, etc. Fireproof boards are widely used in various parts of buildings such as ceilings, walls, and floors.
