There are currently two main categories of steel structure fire retardant coatings at home and abroad: non-intumescent fire retardant coatings and intumescent fire retardant coatings. The former has poor fire protection effect and has been gradually eliminated, while the intumescent steel structure fire retardant coatings are manufactured by Albi Chemical Company of the United States. First invented in 1948. Albi Chemical Company is the first company in the world to produce water-based, low-profile, intumescent fire-retardant coatings for steel structures. Intumescent fire retardant coatings for steel structures mainly include two products: ALBICLAD800 and ALBICLADTF. The former is solvent-based coating , and the latter is water-based coating .
The characteristics of these two fire retardant coatings are: 100% free of asbestos , thin, lightweight, with a high fire protection limit of 3 to 3.5 hours. Hengkeda Group learned that it is in a leading position internationally. Germany and Japan are also very active in research in this field, and many high-performance products have been launched. However, these fire retardant coatings do not have anti-corrosion functions, so they are mainly used for fire protection of indoor steel structures. Over the past half century, this type of thin intumescent fire retardant coating has been continuously developed, and new ones have been continuously introduced from base materials to fire retardant additives. Especially in recent years, due to the requirements of environmental protection, water-based fire retardant coatings have received widespread attention. The annual output value of intumescent fire retardant coatings in developed countries such as Germany, the United States, and Japan is more than 10 million US dollars.
More than twenty years ago, my country began to introduce fire retardant coatings. From the initial thick fire retardant coatings to the current ultra-thin fire retardant coatings, the fire resistance time is getting longer and longer, and the types are getting finer and finer. After more than ten years of development, there are currently several quite good steel structure fire retardant coating companies in my country, which are doing relatively well in terms of technology, products, and construction. However, the entire indoor fire retardant coating market is still a mixed bag. Buying high-quality fire retardant coatings requires keeping your eyes peeled.
Steel structure fire-retardant coating is a must-have for high-rise and super-high-rise buildings, and the role of fire-retardant coatings cannot be underestimated. Steel structure fire retardant coating is used on the surface of flammable substrates. It can reduce the flammability of the surface of the coated material, hinder the rapid spread of fire, and is a special material used to improve the fire resistance limit of the coated material. Steel structure buildings reach a critical point at high temperatures of 540°C, losing their load-bearing capacity and even collapsing in the event of a large fire. The use of steel structure fire retardant coating on steel structures is equivalent to forming a protective film, which can improve the fire resistance limit of steel structures and delay the spread of fire. Class 1 thick fire retardant coatings must be able to withstand a fire that lasts for 3 hours. These three hours provide firefighters with valuable rescue time and can restore immeasurable losses.
Fire retardant coating is a type of functional coating with special significance, which is directly related to the safety of people's lives and property, and to the harmony and safety of society. Promoting the use of water-based fire-proof anti-corrosion coatings with the function of preventing hydrocarbon fires not only has good economic benefits, but also has extremely important social benefits.
