(Summary description)The cable tray is an indispensable part of the power system. It is related to our normal power consumption, so the fireproof function is better. The fireproof mechanism of the fireproof steel cable tray: the expansion foam in case of fire, and some components contained in the paint. In the case of fire, they can react with each other, and the process of generating non-combustible gas is an endothermic reaction, which also consumes a large amount of heat, which is beneficial to lowering the temperature of the system and has an efficient fireproof and heat insulation effect.

Information

The cable tray is an indispensable part of the power system. It is related to our normal power consumption, so the fireproof function is better. The fireproof mechanism of the fireproof steel cable tray: the expansion foam in case of fire, and some components contained in the paint. In the case of fire, they can react with each other, and the process of generating non-combustible gas is an endothermic reaction, which also consumes a large amount of heat, which is beneficial to lowering the temperature of the system and has an efficient fireproof and heat insulation effect. Ultra-thin coatings are thermally decomposed by a large amount of inert gas under the action of high temperature flame. Reduces the concentration of oxygen in the combustible gas and air, slows down or suffocates the fire, and in the event of fire, the coating expands and foams to form an insulating cover, and the foamed layer not only isolates oxygen, but also at high temperatures (about 1000 degrees Celsius) Strong adhesion to steel substrates and good thermal insulation. Its thermal conductivity is very low, delaying the speed of heat transfer to the protected substrate, avoiding direct attack of steel structural parts by flame and high temperature, so the fireproof and heat insulation effect is remarkable.
