Fireproof coatings market overview and its performance analysis

     World 200 meters high above 100 high-rise buildings in steel accounted for 79 percent. Since the reform and opening up, followed by strengthening international exchanges and cooperation between technology, steel application technology in China has been booming, the rapid growth of high-rise and high-rise buildings. From 1984 to 1987 in Beijing, Shenzhen, Shanghai, the three started to build a 11 high-rise steel buildings. According to 1995 statistics, China's completion of 100 high-rise buildings in steel accounted for 37 percent, mostly built in recent years, such as the Beijing International Trade 156.4-meter-high central, 183.5-meter New Jinjiang Hotel, Shenzhen 165 meters high central development and 310-meter-high building and so the king. At present, Shanghai, plans to build ten blocks of high-rise buildings also have a department intends to use steel.
     Back in the 1970s, foreign research and application of fireproof coatings on the positive work carried out and achieved good success, it remains in the ascendant. Early 1980s, foreign fireproof coatings to enter the Chinese market, in engineering applications. From the early 1980s, China has also started to develop fireproof coatings, and now there are more varieties are widely used in various industries.
     With the development of city size, steel reactor in China's construction industry has a very broad vision. But because of their non-combustible steel, thus protecting the steel structure fire insulation topic was once ignored. According to the test reports and statistics information at home and abroad and related organizations indicate that steel building fire performance than the masonry and reinforced concrete structures is poor. The mechanical strength of the steel is a function of temperature, in general, can be thought that the mechanical strength of the steel decreases with increasing temperature, at about 5000C, the strength decreased to 40% to 50%, mechanical properties of steel, such as yield point, compressive strength, elastic modulus, and load capabilities have decreased rapidly, quickly lose their ability to support. Cause buildings to collapse. Therefore, it is imperative for the protection of steel structures. Fire protection of steel structures in many forms and measures, including the use of fire-resistant coating is an ideal approach. Fireproof paint brush or spray on the steel surface, plays the role of fire insulation to prevent the steel in the fire rapidly warming and reduce the strength, the ability to avoid the loss of support caused steel buildings collapse. Fireproof coating characteristics are high strength, light weight with good extension, seismic and short construction period.
