The Composition, Types, Characteristics, and Uses of Fire-resistant and Wear-resistant Plastics

The composition of fire-resistant and wear-resistant plastics is similar to other amorphous refractory materials. It is composed of refractory aggregates and powders, binders, and plasticizers. Special admixtures can be added according to different use requirements.

There are many types of fire-resistant and wear-resistant plastics. According to the binding agent, they are clay-bonded plastics, phosphate-bonded plastics, aluminum sulfate-bonded plastics, tar-asphalt or resin-bonded plastics, etc.; according to the materials, they are silicone, clay, high alumina, corundum, zircon, carbon or silicon carbide, magnesia, and magnesium chromium, etc. Commonly used refractory plastics are mainly aluminum silicate (clay or high alumina) plastics.

Fire-resistant and wear-resistant plastics have good medium and high-temperature bonding strength, good wear and thermal shock resistance, and are resistant to peeling.

Fire-resistant and wear-resistant plastics are widely used in industrial kilns in the metallurgy, petrochemical, electric power, and machinery industries. They are mainly used as thermal shock-resistant, erosion-resistant, and wear-resistant linings; such as burners for heating furnaces and cement rotary kilns. The discharge port, the feed port of the vertical kiln, the lining of the high-temperature cyclone separator, the roof and furnace wall lining of the steel rolling heating furnace, and can also be used as the lining of various heat treatment furnaces.
