Overview
Fireproof coatings are specialty coatings that are used to increase the fire resistance limits of combustible substrate surfaces. By painting on the surface of the material, fireproof coating can reduce the combustibility of the material surface, slow down the spread of flame propagation speed, or can prevent combustion within a certain period of time. There are many types of fireproof coatings, generally according to the use of fireproof coatings and the coating thickness of fireproof coatings are categorized into finish coatings and steel structure fireproof coatings.
1.Fireproof coating, as a kind of special coating, has the following advantages: 1, strong thermal insulation: fireproof coating can effectively isolate the heat source, slow down the spread of fire, and play the role of fire prevention and thermal insulation.
2, light weight, high strength: fireproof coating is generally lightweight and high strength materials, with a specific gravity lighter than water and comparable to wood, which can give full play to its advantages of light weight, high strength, good ductility and strong seismic capacity.
3、With fire resistance and flame retardant: fireproof coating makes heat transfer slow, can effectively resist fire and protect its structure from fire.
4, sound absorption, sound insulation function: different thickness of fireproof coating has different noise reduction effect, up to 30-50 decibels.
5、Environment-friendly:Fireproof coating decomposes into non-combustible inert gas when heated, diluting the combustible gas decomposed by the protected object when heated, so that it is not easy to burn.
Description
Fireproof coatings are specialty coatings that are used to increase the fire resistance limits of combustible substrate surfaces. By painting on the surface of the material, fireproof coating can reduce the combustibility of the material surface, slow down the spread of flame propagation speed, or can prevent combustion within a certain period of time. There are many types of fireproof coatings, generally according to the use of fireproof coatings and the coating thickness of fireproof coatings are categorized into finish coatings and steel structure fireproof coatings.
Fireproof coating, as a specialty coating, has the following advantages:
1, strong thermal insulation: fireproof coating can effectively isolate the heat source, slow down the spread of fire, play the role of fire insulation.
2, light weight, high strength: fireproof coating is generally lightweight and high-strength materials, the specific gravity of which is lighter than water and comparable to wood, which can give full play to its advantages of light weight, high strength, good ductility and strong seismic capacity.
3, with fire resistance, fire retardant: fireproof coating makes heat transfer slow, can effectively resist fire, and protect its structure from fire.
4, sound-absorbing, sound insulation function: different thickness of fireproof coating has different noise reduction effect, up to 30-50 dB.
5,Environmentally friendly: Fireproof coating decomposes into non-combustible inert gas when heated, diluting the combustible gas decomposed by the protected object when heated, so that it is not easy to burn or slow down the burning speed. At the same time, the fireproof coating contains nitrogen, and the NO, NH3 and other groups decomposed by heating can combine with organic free radicals to block the chain reaction and reduce the temperature.
Overall, fireproof coatings have a variety of advantages and are widely used in a variety of fields, and have a very important role in fireproofing and heat insulation.
