Paint is one of the most widely used building materials at present, and its bright colors add a lot of colors to our home. With the development of the times, there are more and more kinds of coatings, and the safety is getting higher and higher. So, do you know what a new paint is? How to distinguish new paint?
A New Type of Coatings —— Fireproof Coatings for Steel Structures
Steel structure is one of the main forms of high-rise buildings and has a good development prospect. Therefore, we must have unique fire prevention measures for such an important building form. Although it is a non-combustible material, in case of fire, it may be seriously affected under long-term high temperature, such as deformation or collapse of steel structure. Therefore, we must coat the surface of rigid structure with a layer of fireproof and heat-insulating material, so it is called fireproof coating for steel structure.
New coating Ⅱ: Thick-coated fireproof coating for steel structure
Thick-coated fire retardant coating for steel structure generally refers to the coating with a thickness of 8 mm to 50 mm, which can play a good role in fire prevention and heat insulation, and generally will not cause any adverse impact on steel structure within three hours. Despite this advantage, the decorative effect is relatively poor because of the thick coating.
New coating Ⅲ: Bo Tu fire retardant coating for steel structure.
Bo Tu fire retardant coating for steel structure is contrary to the above. The coating thickness of this kind of coating is between 3 mm and 7 mm, and its fire prevention and heat insulation is mainly an insulation layer formed by the expansion and foaming of the coating after heating, which delays the heating time of the steel structure, thus achieving the effect of heat insulation and fire prevention, and has a certain decorative effect on the building.
Four new coatings: ultra-thin fireproof coatings for steel structures.
With the continuous improvement of people's appreciation level, the above fire retardant coatings have been difficult to meet people's pursuit of beauty. Therefore, after years of research, a new ultra-thin fire retardant coating for steel structure has been developed recently. The so-called ultra-thin coating refers to the coating with a thickness of less than 3 mm The heat insulation effect of this coating is mainly achieved by the dense flame-retardant insulation layer formed by expanding bubbles after heating, which is better in decoration than any of the above coatings, but its heat insulation time is relatively shortened.
