What are the fire-resistant coatings and which buildings are suitable for them
Fire-resistant coatings are relatively common paint coatings on the market today. What are the fire-resistant coatings, what are their characteristics, and what are their corresponding ranges of use?
What are the fire-resistant coatings
Thick steel structure fireproof coating
It is mainly composed of inorganic flame retardant and heat insulation materials such as desulfurized gypsum. The product has the characteristics of strong corrosion resistance, high compressive strength, good water resistance, light specific gravity, long fire resistance time, etc. The use of this coating can greatly reduce the weight of the fireproof coating compared with the cement-based fireproof coating, relying on the superior anticorrosive performance of the coating It can be exempted from anti-corrosion construction and is suitable for fire protection of indoor steel structure buildings with high fire resistance requirements such as stadiums, terminals, and large workshops.
Thin steel structure fireproof coating
It is an emulsion fireproof coating made of water-resistant organic resin with excellent weather resistance, inorganic polymer materials, fillers and additives. Because the coating can form a thicker fire insulation layer in case of fire, the steel structure is protected from heat during a fire, and its strength will not drop sharply under the high temperature of the fire and cause the building to collapse. WB-AWS outdoor thin steel structure fireproof coating has a thin coating, good physical and chemical properties and fireproof performance, and outstanding decorative effects. It is suitable for fire protection of bare steel structures in outdoor buildings and structures.
Ultra-thin steel structure fireproof coating
Modified composite resin, flame retardant, carbonizing agent, expansion agent and auxiliary agent are used as raw materials for compounding with advanced technology. The product has the characteristics of salt spray resistance, corrosion resistance, freeze-thaw resistance, acid and alkali resistance, etc., and is suitable for fire protection in open-air steel structures such as industrial plants, stadiums, petrochemicals, oil and gas tank brackets, mine drilling, waiting halls, and television towers. protection.
Tunnel fire coating tunnel
The significant features of this product are: thin coating, high fire resistance, high bonding strength, good weather resistance, no toxic gas is generated during combustion. In recent years, the continuous increase of traffic tunnels and underground engineering in China has brought new challenges to fire safety, promoted basic research on tunnel fires, and based on the characteristics of fire-proof and heat-insulating coatings for concrete, the characteristics of fire protection for tunnel concrete structures And needs, jointly developed with the Sichuan Fire Research Institute of the Ministry of Public Security to develop fireproof coatings for tunnels. It is suitable for fire protection of concrete structures such as roads, railways, street tunnels and underground engineering.
Cable fireproof coating is a solvent-based intumescent fireproof coating. This coating is prepared by using the latest technology, using modified acrylic resin as the base material, and adding a variety of flame retardants, additives, pigments, etc. The coating is characterized by a uniform and dense sponge-like foam layer after fire, has significant fire and heat insulation effects, and has good waterproof and moisture resistance, oil and weather resistance, that is, fire retardant and high decoration effect.
Fire-resistant coatings have a lot of room to play in many areas of the construction industry, and they have attracted attention from all walks of life. There are many types of fire-resistant coatings for different items. There are several different types of fire-resistant coatings for steel structures alone. Therefore, when selecting fire-resistant coatings, we must consider the scope of his application.
