Abstract
The invention discloses a copper alloy acid pickling passivant. The copper alloy acid pickling passivant is composed of, by mass, 5-15 parts of silver sulfate, 5-15 parts of aluminum sulfate, 5-15 parts of copper sulfate, 5-15 parts of magnesium sulfate, 60-75 parts of phosphoric acid, 8-10 parts of sodium phosphate, 8-10 parts of calcium phosphate, 8-10 parts of iron phosphate, 10-15 parts of ferrous sulfate, 10-12 parts of silver nitrate, 10-12 parts of copper nitrate, 10-12 parts of ferric nitrate, 10-20 parts of benzotriazole, 8-15 parts of sodium dodecyl sulfate and 200-300 parts of purified water. The copper alloy acid pickling passivant is simple in process, the discolored portion of the copper alloy surface can be completely removed, the cleaning effect is achieved within short soak time, it is guaranteed that no rust return phenomenon is generated between procedures because the copper surface is passivated, and the operating hazard is extremely low.
Description
Technical field
The present invention relates to the technical field of passivator, particularly relate to an Albatra metal-passivating agent for acid-washing.
Background technology
At present, Copper and its alloy goods widely use in fields such as heavy industry, light industry, household appliances and instrument appliance products.But Copper and its alloy is easy oxidation discoloration in an atmosphere, goods particularly can be made in the presence of a harsh environment to get rusty, form verdigris, change the color and luster that copper is original.This not only affects the visual appearance of product but also has damaged some performances of itself.For this reason, many facing operation persons, through long-time effort, develop many special treatment processs.Both prevent product itself to be oxidized, and give again product appearance attractive in appearance.In many treatment processs, chemical pickling method because of its cost minimum, efficiency higher and application comparatively extensive.
Decontamination; protection ring wall is the basic demand of human survival, and our several generations scientific worker is through unremitting effort; progressively there being the copper piece acid washing passivation technology of higher hazardness to be converted into low concentration, the acid washing passivation technology of less contamination operation of putting into production.But, although tobacco and pollution of chromium have been in lower numerical value, but still fail to reach free of contamination copper alloy bright dipped finish and the processing requirement without network passivation.
Summary of the invention
The object of the invention is the shortcoming in order to overcome above-mentioned prior art, one Albatra metal-passivating agent for acid-washing is provided, the technique of this copper alloy passivating agent for acid-washing is simple, copper alloy surface color change portion can be removed clean, cleaning effect is reached in the soak time of short period of time, and ensure not occur returning rust at inter process to copper surface passivation, operation hazardness is extremely low.
The technical solution adopted for the present invention to solve the technical problems is: an Albatra metal-passivating agent for acid-washing, is made up of the composition of raw materials component of following mass percent: 5-15 part Sulfuric acid disilver salt, 5-15 part Tai-Ace S 150,5-15 part copper sulfate, 5-15 part magnesium sulfate, 60-75 part phosphoric acid, 8-10 part sodium phosphate, 8-10 part calcium phosphate, 8-10 part tertiary iron phosphate, 10-15 part ferrous sulfate, 10-12 part Silver Nitrate, 10-12 part cupric nitrate, 10-12 part iron nitrate, 10-20 part benzotriazole, 8-15 part sodium laurylsulfonate, 200-300 part pure water.
Further, 5 parts of Sulfuric acid disilver salts, 5 parts of Tai-Ace S 150,5 parts of copper sulfate, 5 parts of magnesium sulfate, 60 parts of phosphoric acid, 8 parts of sodium phosphates, 8 parts of calcium phosphate, 8 parts of tertiary iron phosphates, 10 parts of ferrous sulfate, 10 parts of Silver Nitrates, 10 parts of cupric nitrates, 10 parts of iron nitrates, 10 parts of benzotriazoles, 8 parts of sodium laurylsulfonates, 200 parts of pure water are comprised.
Or, comprise 15 parts of Sulfuric acid disilver salts, 15 parts of Tai-Ace S 150,15 parts of copper sulfate, 15 parts of magnesium sulfate, 75 parts of phosphoric acid, 10 parts of sodium phosphates, 10 parts of calcium phosphate, 10 parts of tertiary iron phosphates, 15 parts of ferrous sulfate, 12 parts of Silver Nitrates, 12 parts of cupric nitrates, 12 parts of iron nitrates, 20 parts of benzotriazoles, 15 parts of sodium laurylsulfonates, 300 parts of pure water.
In sum, the invention has the beneficial effects as follows: the technique of copper alloy passivating agent for acid-washing of the present invention is simple, copper alloy surface color change portion can be removed clean, cleaning effect is reached in the soak time of short period of time, and ensure not occur returning rust at inter process to copper surface passivation, operation hazardness is extremely low.
