Microcomputer based steel structure fireproof coating insulation efficiency test furnace

Research on Thermal Properties of Expanded Fireproof Coatings——Steel structure fireproof coating insulation efficiency limit test furnace
At present, China is still in the wave of infrastructure construction, and steel structures are becoming increasingly popular in engineering Expansion type fireproof coatings have the advantages of good thermal insulation performance, low cost, lightweight and beautiful appearance, flexible construction, and environmental friendliness. Therefore, they have been widely used for fire protection of steel structures Coatings undergo a series of thermal, physical, and chemical reactions under the action of fire, resulting in continuous changes in the thickness of the coating and various thermal properties. This poses difficulties in calculating the temperature of steel components protected by fire-resistant coatings under fire
