Coating protective agent process for copper bar surface treatment
15
Copper bar coating protective agent can maintain the original color of the copper bar, which is slightly lower than the cost of tinning.But the operation cycle is long.The process flow of coating protective agent generally needs: first polishing pretreatment→pure water washing→pickling passivation work piece→drying moisture→JLR-510 protection treatment→washing in flowing water→hot water soaking (about 100℃, it needs to be used for heating up the work piece) , The purpose is to let the water volatilize or dry by itself)→drying→packing closed.Copper bar surface treatment process polishing: both manual and mechanical are slow, and tired, the dust is very serious, clean up the surface oxide scale, small burrs. The main process of pickling passivation is: pre-treatment (purification of the surface) → pickling passivation and washing → post-treatment (protection of finished products).The main content of the pre-treatment is to purify the surface of pickling and passivation parts, remove all kinds of grease, welding spatter, welding scars, oxide scale, etc. on the surface.Pickling and passivation can be processed separately, or the pickling and passivation can be combined into one for simultaneous processing.When pickling and passivation are treated separately, the method of immersing the workpiece in the pickling and passivation solution is often used, which is suitable for small parts or pipelines and linear equipment with internal liquid circulation..When pickling and passivation are combined into one treatment, liquid soaking can be used (the suitable range is the same as above), or paste can be used for application. Because the paste is easy to apply, it can be kept for a long time at different positions without loss and wetting So as to ensure the necessary time for pickling passivation.
