What color of fireproof mud is used for fireproof sealing of bridge

There are many red colored fireproof muds used for bridge fireproof plugging. The polymer fireproof muds produced by our company are mainly divided into white, black, gray and red. Other colors can be customized. The polymer fireproof muds used for bridge fireproof plugging have superior weather resistance, insulation, temperature resistance and hydrophobicity, and have certain flame retardancy. At present, it is widely used in the field of electrical product bonding. It is a material with the requirements of insulation, weather resistance, waterproof, fireproof and corrosion resistance. Waterproof, fireproof, insulation, corrosion resistance, weather resistance, non drying, self-adhesive materials.

The performance of the new polymer fireproof mud compared with the ordinary fireproof mud:

　　 one Non corrosive cable and box containing halogen corrosive metal and cable

　　 two No mildew, surface mildew

　　 three Good insulation performance, breakdown voltage greater than 15KV/mm Poor insulation performance, breakdown voltage 19.2 KV/mm

　　 four Good resistance to tracking and electric corrosion, TMA Not less than four point five Grade I has poor resistance to tracking and electric corrosion, TMA Not greater than two point five level

　　 five Good hydrophobicity, good sealing, water absorption, poor sealing

　　 six No solidification, no fission, hard and cracking

　　 seven No low molecular substances, no oil seepage and small molecular oil precipitation

8 Long term high temperature resistance 200 ℃, short term high temperature resistance

Scope of application:

The new polymer fireproof mud is widely used in various power generation, power supply and distribution equipment systems in important places such as power plants, power transmission and transformation, smelting industry, industrial and mining enterprises, subways, hospitals, high-rise buildings, telecommunications, ships, nuclear power plants, as well as the sealing materials for ventilation pipes, oil pipes, firewall panels and doors and windows, which has a significant function of preventing fire and smoke spread. It is used for fireproof sealing of holes of wires, cables, communication optical cables, to prevent the fire of wires, cables and optical cables from spreading from holes to adjacent rooms and reduce fire losses. It mainly avoids the expansion of accidents and has the functions of smoke prevention, fire prevention and dust prevention.
