The brass tube is pre-polished and pre-treated→pure water washing→pickling passivation workpiece→drying water→JLR-510 protection treatment→washing in running water→hot water soaking (about 100°C, used to heat up the workpiece, the intention is to let the water Evaporation or drying) → drying → packaging and sealing the brass tube. Copper tube surface treatment process polishing: whether it is manual or mechanical, it is slow and tiring, and the dust is very serious. Clean the outer skin and small burrs. The main process of pickling passivation is: pre-treatment (cleaning appearance) → pickling passivation and rinsing → post-treatment (product protection). The main content of the pre-treatment of brass tubes is to purify the surface of pickling and passivation objects, and to clean all kinds of grease, welding spatter, welding scars, skin, etc. on the surface. Pickling and passivation can be treated separately, or can be combined into one and processed simultaneously. When pickling and passivation are separated, the method of immersing the entire workpiece in the pickling and passivation solution is often used, which is suitable for small parts or pipelines and linear equipment that can circulate liquid inside. When the brass tube is combined with pickling and passivation, you can use the liquid immersion method (the applicable range is the same as above), or you can use the paste for modification, because the paste is easy to apply, and the brass tube can be maintained for a long time in different positions. No run off and wettability at all times, then ensures the necessary time for pickling passivation.
