The basic concept is to control the airflow to drive the speed of the variable speed machine in an instant, so that the hydraulic cylinder of the air motor can move continuously. The inhaled paint is transferred to the spray gun of the spraying machine through the hydraulic hose, and the spray gun releases the architectural paint to the surface of the object to be painted. Fire retardant paint spraying machine sprays fire retardant paint.

[0003] At present, the coating in the fire retardant coating sprayer is usually added manually, but the fire retardant coating is mainly made of a mixture of fire retardant coating base material, glue and water.
