SOFT ACID ELECTROLYTE FOR GLOSSY ZINC COATING |
| 摘要 |
The electrolyte comprises sodium chloride 100-200, zinc chloride 40-100, boric acid 15-40, benzalacetone 0.1-1.2, nonyl phenol ethoxylated with 25 mole of ethylene oxide 5-20 sodium salicylate 1-10, and N-(2,3-dihydroxypropyl)-pyridine chloride or sulphate 0.05-0.25 g/l and ethyl alcohol 2.5-6 ml/l. The operating parameters are 18-30 deg. C pH = 4.0-6 and cathodic density 0.5-5 pref. 2-3 A/dm2. The ductile uniform coating can be applied to steel, iron copper and copper alloys in static and in drum-type baths.
