The steel structures preservation line shot blasting and painting line is used for derusting and painting the surface of steel plates and section steels in the steel prefabrication workshop of the shipyard. It is mainly used to derust the steel surface that need to be pretreated and spray shop primer. Through the pretreatment of the steel, the surface rust, oxide scale and dirt are removed, so that the steel has a clean and certain surface, so as to enhance the adhesion between the paint film and the surface of the steel, thereby ensuring the anticorrosive coating quality of the steel. Workshop primer, so that the steel will no longer be damaged by secondary pollution during the processing, and a clean, rust-free and pollution-free surface is reserved for the final coating operation to ensure the coating quality.
Process flow:
Loading rollers → shot blasting and derusting → spraying primer → drying → feeding rollers
