The fire-retardant characteristics of building fire-proof materials
At any time the development of society, economic affluence, in countless large cities more and more can be found in high-rise buildings rising up, the problem then comes, high-rise building fire, and the key factor is the choice of flame retardant building materials, fire retardant material plays a vital role.
1. Flame and fire resistance of objects
Combustion is a violent oxidation reaction accompanied by exothermic and luminous effects. Exothermic, luminous and new substances are the three characteristics of the phenomenon of combustion. The combustible material, the combustible material and the ignition source are often referred to as the three elements of combustion.
2. Flame retardants
There are various types of flame retardants that have been industrialised, mainly designed for the flame retardation of polymeric materials. According to the method of use, flame retardants can be divided into two categories: flame retardant additive and reactive flame retardants.
3. Fire retardant coatings
Fire retardant coatings are substances that are applied to the surface of an object to reduce the flammability of the surface and block the spread of heat to the object, thus preventing rapid heating of the object, stalling the spread of fire and increasing the fire resistance limit of the object. Fire resistant coatings are mainly composed of two parts: the base material and the fire protection additives.
