① The process procedure of the dip coating process is:
Pre-painting treatment (including degreasing, rust removal, water washing, neutralization, phosphating, water washing, drying or drying) → surface cleaning → dipping paint → drying → quality inspection → storage.
② Brushing process For the skin parts after phosphating treatment, first use rags or clean cotton yarn to wipe off the white powder produced by the phosphating process on the surface, and then use iron red, gray or black (according to process requirements) ) Phenolic anti-rust paint or alkyd anti-rust paint, just apply one coat evenly. For workpieces that require anti-rust paint on one side, care should be taken to keep the other side clean. For the large body skin that cannot be phosphating, the oil stain inside (leave it alone on the outside) can be wiped clean with gasoline, then polished , and the paint can be painted after wiping off the floating powder.
