Description
Technical field
The present invention relates to hardware stamping part process for treating surface, and in particular to a kind of hardware stamping part surface passivating treatment
Liquid.
Background technique
Passivation Treatment is the last one processing step in chemical cleaning, is a crucial step, its purpose is to the anti-of material
Corrosion.If boiler rinses, after rinsing through pickling, water, metal surface is cleaned very much, is activated very much, it is easy to be corroded, so must
It must be passivated processing immediately, the metal surface after making cleaning generates protective film, slows down corrosion.
Common passivating solution is chromate at present, and chromium environmental pollution is serious.Since slacking enters the chromium in soil, hold
The oxidizable composite anion at solubility, is then transferred in the surface water or underground water by elution.When chromium is excessive in soil,
It can inhibit the nitrification of organic substance, and accumulate chromium in plant.Trivalent chromium and Cr VI have cause to aquatile
Dead effect.Trivalent chromium in water body is mainly attracted on solid matter and is present in deposit；Cr VI then more is dissolved in water
In.Cr VI is stable in water body, but can be reduced to trivalent chromium under anaerobic.The salt of trivalent chromium can neutral or
It is hydrolyzed in weakly alkaline solution, generates chromium hydroxide not soluble in water and sink under water.
Micro chromium is generally contained only in natural water, and sea is conveyed by river, is sunken to seabed.Chromium content in seawater less than
1ppb.According to test, plant growth can be stimulated in 1ppm containing chromium in water, and when 1~10ppm can be such that plant growth slows down, and arrive
Then almost crop is made to stop growing when 100ppm, is on the verge of death.Contain chromium compound in waste water, can reduce at wastewater biochemical
Manage efficiency.
Summary of the invention
In view of the above shortcomings of the prior art, the present invention provides a kind of hardware stamping part surface passivation treating liquid, no chromic acid
Salt, safety and environmental protection are pollution-free.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of hardware stamping part surface passivation treating liquid, including following component: inorganic inhibitor 5-20g/L, rare-earth salts 2-
15g/L, organic acid 0.5-2.5g/L, activating agent 0.5-2.5g/L.
Preferably, the inorganic inhibitor is molybdate.
Preferably, the rare-earth salts is ammonium ceric nitrate, hydrogen oxide ammonium, cerous acetate, samarium oxide, lanthanum nitrate, zirconium nitrate.
Preferably, the organic acid is carboxylic acid.
Preferably, the activating agent is metal oxide, hydroxide and subcarbonate.
It is simple and practical that the invention has the following beneficial effects: inventive formulations, chromate-free, and safety and environmental protection is pollution-free；Institute
The passivating film adhesive ability of generation is strong, and film layer is fine and close, and has good anti-scratch ability.
