Abstract
The invention relates to a trivalent chromium white passivating liquid, wherein, galvanized parts are immersed into chromium trioxide, seignette salt, sulphuric acids and nitric acids; galvanized parts obtaining white passive films are immersed into chromium trioxide, sodium sulfate, sulphuric acids, nitric acids and potassium permanganate low chromic acid passivating liquid; after passivation again, low chromium iridescent passive films can be obtained. The invention has the advantages of capability of directly exhausting cleaning water after passivation, stable nonirritant odor, safe operation and strong corrosion resistance.
Description
Technical field
The present invention relates to a kind of technique for preparing trivalent chromium white deactivation liquid.
Background technology
At present, influence workers ' health for solving existing zinc electroplating with blue or clear chromate conversion coating technology iris flag bleaching processing, cause problem of environmental pollution, with low chromic acid passivation, but need often to adjust passivating solution, it is aging to go out the inkstone passivating solution, and passive film does not work, sends out mist, easily comes off, the low anticorrosion and decorative value of battle array can not widespread use.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of technique for preparing trivalent chromium white deactivation liquid is provided.
Technical scheme of the present invention is: a kind of technique for preparing trivalent chromium white deactivation liquid, it is characterized in that: galvanized workpiece is immersed chromic anhydride 40 grams per liters, Seignette salt 50 grams per liters, sulfuric acid 30ml/ liter, nitric acid 10ml/ liter, the galvanized workpiece that will obtain the white chromating film again immerses chromic anhydride 5 grams per liters, sodium sulfate 1-2 grams per liter, nitric acid 3-5ml/ liter, passivation again in the potassium permanganate 1-1.5 grams per liter low chromic acid passivation solution just can obtain low chromium iridescent passivation film.
The present invention has the following advantages: rinse water can directly be discharged after the passivation; Stable have no irritating odor, operational safety; Erosion resistance is strong.
Embodiment
Embodiment: a kind of white passivating liquor containing trivalent chromium, galvanized workpiece is immersed chromic anhydride 40 grams per liters, Seignette salt 50 grams per liters, sulfuric acid 30ml/ liter, nitric acid 10ml/ liter, the galvanized workpiece that will obtain the white chromating film again immerses chromic anhydride 5 grams per liters, sodium sulfate 1-2 grams per liter, nitric acid 3-5ml/ liter, passivation again in the potassium permanganate 1-1.5 grams per liter low chromic acid passivation solution just can obtain low chromium iridescent passivation film.
