Fire Resistant Spray Coating

The technical characteristics of the refractory spray paint:

The fire-resistant spray coating is constructed with the spraying method. The material mix ratio, the spraying operation, the rebound rate and the dressing process are as follows. The mixture ratio of spray coating should meet the following requirements: to achieve the required strength, less springback, less spray dust, good adhesion and no blockage of the pipeline. When the cement binder is used for dry or semi dry spraying, the amount of cement is about 20% ~ 25% of the total material. When the cement is too much, the amount of dust increases when the spray is sprayed, and the shrinkage of the spray coating increases after the hardening.

Refractory spray coating is an amorphous refractory material constructed by mechanical spraying using pneumatic tools. It is composed of refractory aggregate, powder, binder (or external agent). Since the cement and aggregate and other component materials are repeatedly impacted during the spraying process to compact the sprayed materials, the sprayed coating has good density and mechanical strength. Spraying construction actually combines transportation, pouring or tamping into one process, without or only requiring a single-sided template. The process is simple, efficient, and has a wide range of adaptability.
