|Coating refractory consists of refractory aggregate, powder and binder (or additive). Good results have been achieved both in spraying furnace construction and in repairing furnace lining.|
The construction of fire-resistant paint spraying is to combine transportation, pouring or tamping into one working procedure, with simple working procedure, high efficiency and wide adaptability. During the construction of refractory paint spraying, the sprayed materials are compacted by repeated and continuous impacts of cement and aggregate, so the sprayed coating has good density and mechanical strength. The material has the characteristics of good adhesion, low rebound rate and high strength.
The particle size of the coating refractory should not be larger than 5mm, because if it is 5mm, the spray gun will be blocked, which will prevent normal construction. During construction, the fire-resistantcoating refractory is sprayed in the pipeline for 40-50mm, and the spray coating can be formed quickly. At present, there are many spraying methods, but spray gun is usually used. Application: This product is mainly used in high temperature pipes, hot air pipes and flue systems of blast furnaces and hot blast stoves. It is suitable for building various industrial kilns, such as blast furnaces, hot-blast stoves, coke ovens, oil refining furnaces, electric furnaces, glass pool furnaces, power plant boilers, petrochemical industrial furnaces, etc.
