Embodiment Construction
[0014] The chrome-plating method for stainless steel conductive rollers includes polishing, cleaning, degreasing and roughening the surface of the roller body by conventional operating methods, and then:
[0015] (1) peak cutting and deburring
[0016] Prepare the peak cutting and deburring solution at room temperature, take 770ml of water, add HNO in turn 3 135g, HCl65g, HF 30g, C 6 h 12 N 4 (Hexamethylenetetramine) 2g, stir evenly.
[0017] Take the φ600×12121Cr18Ni9Ti stainless steel conductive roller as an example, textured to Ra 3~5, after cleaning, brush the surface of the textured layer with a peak-shaving deburring solution, wipe the surface of the roller for 15-20 minutes, wash, and remove the roughness formed during texturing. The waste edge and debris are dissolved;
[0018] (2) 1Cr18Ni9Ti stainless steel conductive roller surface chrome plating
[0019] Preparation of chrome plating solution: CrO 3 (Chromic anhydride) 250g / L solution, with CrO 3 :H 2 SO ...
