Embodiment 1
[0032] A spraying preparation method for processing aluminum profiles, comprising the following steps:
[0033] S1. Substrate pretreatment: pretreat the aluminum profile before spraying, derust the rust layer and rust spots on the surface of the aluminum profile, use equipment to remove the welding points and welding slag of the aluminum profile, and use a rust remover To remove the rust layer and rust spots on the surface of aluminum profiles, high-efficiency corrosion inhibitors are added to the rust remover, and the welding points and welding slag are removed by grinding equipment, and the dust collection equipment is used to reduce dust flying while grinding;
[0034] S2. Water washing and alkali washing: Pour pure water and cleaning agent into the cleaning equipment. The cleaning agent is an industrial degreasing cleaning agent. Put the aluminum profiles into the cleaning equipment for cleaning. After cleaning, put the aluminum profiles in the aluminum washing tank for use...
