Description
technical field
[0001] The invention belongs to the technical field of coatings, and more specifically, the invention relates to a fireproof and radiation-proof coating for thick steel structures. Background technique
[0002] With the development of industrialization, especially in the construction of large and medium-sized cities, steel structures have become a very important construction application material due to their fast and convenient construction advantages. As metal steel structures, they are mostly used in standard In factories, large stadiums, airports, bridges, three-dimensional garages and nuclear buildings. However, the fire resistance of steel structures is far inferior to that of brick-concrete structures. The critical temperature of steel is 540°C. When this temperature is reached, its bearing capacity will be reduced by about half. In a general fire, this temperature can be reached in about 15 minutes, leading to the collapse of the building. This chara...
