usage method
(1) According to the processing condition of the workpiece, the oil and grease shall be removed, and the wax of the mechanical polishing parts shall be removed first (our & ldquo; general wax removal cleaning agent & rdquo; can be used) Flush water after cleaning to ensure that the surface is clean;
(2) Pickling or activation: before passivation of parts with machining processes such as welding, rolling or heat treatment, pickling shall be carried out (3-10% dilute sulfur and acid can be used) for 2-5 minutes (the specific time can be controlled by yourself, mainly removing the oxide skin and exposing the metal matrix), or directly use the & ldquo; Special activation solution for stainless steel & rdquo; Pickling; All workpieces with electrolytic polishing, chemical polishing, mechanical grinding and polishing, clean surface, no oxide scale and rust spots can be passivated directly;
(3) Place the cleaned workpiece in the passivation solution and soak it completely for more than 30 minutes (generally 30 minutes
For those with higher requirements, the passivation time can be appropriately extended
The longer the time, the more complete the passivation film)
Take it out and wash it with clean water * and then use the neutralization solution (3% - 8% sodium hydroxide solution) for neutralization and antirust treatment
(4) Do not use well water for cleaning, use tap water for cleaning, and there shall be no residue on the surface of the workpiece;
(5) After that, soak and wash with clean water (purified water or filtered soft water) with chloride ion content less than 25ppm for 3 minutes,
Stainless steel passivation solution, no oil stain, no oxide, Zhijian stock solution can be soaked at room temperature!
