1. The two types of refractory spray coatings use different refractory materials. Lightweight refractory spray coatings use lightweight aggregates as the main refractory material during production, while heavy refractory spray coatings use heavy aggregates as the main refractory material during production and processing.
2. Due to different raw materials used in production, fire-resistant spray coatings are applied in different industrial kilns and locations. Lightweight refractory spray coatings are generally used as insulation layers for industrial kilns; Heavy duty refractory spray coating is applied to the working layer of industrial kilns, in conjunction with anchor components for construction.
3. From the names of the two types of refractory spray coatings, lightweight refractory spray coatings have a lighter volumetric density, while heavy refractory spray coatings have a heavier volumetric density.
