High temperature performance of high strength wear-resistant and fire-resistant spray coatingPublished by:2021-9-12 Categories:News Viewed by: 5894 times During construction, the fire-resistant spray coating is a kind of sprayed and sprayed refractory material. It is an amorphous refractory material that can resist the friction or scouring of high-temperature solid materials or air flow containing solid powder, which is made by taking High-strength Mineral Admixture aggregate as the main refractory raw material, adding fire-resistant cement binder, then adding anti crack and wear-resistant agent and fire-resistant powder. High strength wear-resistant spray coating is used for different high-temperature kilns and made of different refractory raw materials, such as fire-resistant spray coating for boilers. High strength wear-resistant spray coating is made of corundum, silicon carbide and bauxite as the main refractory raw materials, adding ultra-fine powder, composite admixture and other high-temperature resistant materials after mixing. High strength and wear-resistant spray coating has the characteristics of good high temperature performance, high strength at medium and high temperature, stable volume, corrosion resistance, erosion resistance, strengthening the overall structure of boiler lining and so on.
Refractory materials for cement rotary kiln are mainly strong and wear-resistant materials, which can resist the impact and scouring of materials in the kiln and ensure the normal operation of the rotary kiln.
When the high-strength wear-resistant and fire-resistant spray coating is used on site, add water for mixing to ensure that the mixture is uniform and can be put into use. It is convenient for construction. A certain thickness of wear-resistant layer is formed on the surface of the silo or ore tank by manual spraying, which can meet the technical requirements after normal maintenance. It has the characteristics of high wear resistance, strong impact resistance, high compressive strength, good durability and long service life.
High strength wear-resistant and fire-resistant spray coating can be used for lining wear-resistant layer of slag gully, ore chute, coal unloading chute, lower hopper and material silo in metallurgy, coal, thermal power, chemical industry, cement and other industries. High strength wear-resistant and fire-resistant spray coating has stable performance in high temperature environment. |
