Abstract
The invention provides a rust removal activating agent solution which is characterized by comprising the following components in percentage by weight: 15-40% of sulfuric acid, 2-20% of hydrochloric acid, 5-25% of potassium monopersulfate, 0.1-1% of fatty alcohol polyoxyethylene ether and the balance of water. The rust removal activating agent solution has the advantages of little hazard, wider applicability and high rust removal activating speed.
Description
Technical field
The present invention relates to a kind of activator, relate in particular to a kind of rust cleaning activator, the invention still further relates to a kind of compound method and using method of the activator that eliminates rust.
Background technology
The rust cleaning activator is the chemical products that semiconductor integrated circuit plating, junctor plating etc. are removed the surface oxide layer of metal base before plating.Mode of operation adopts high-speed and continuous immersion, hanging frame type immersion, drum-type to soak.Mostly the rust cleaning activator that electroplating industry is commonly used at present is to adopt dilute sulphuric acid, dilute hydrochloric acid or their mixture.Use these acid treatment metal oxide layers usually can remove unclean, especially causing oxidation serious metallic surface to feel simply helpless due to complete processing or storage condition.In addition, metal base is immersed in soak time required in these rust cleaning activators more than 10 minutes, the production capacity of production line, the design of production line are restricted; Because the rust cleaning activator is acidic substance mostly, near the corrosion of component or the equipment in use volatilization of acid gas easily causes.
Summary of the invention
Technical problem to be solved by this invention is to provide that a kind of hazardness is less, and suitability is wider, the fast rust cleaning activator solution of rust cleaning activating velocity.
For solving the problems of the technologies described above, the invention provides a kind of activator solution that eliminates rust and comprise the sulfuric acid that degree is 15-40%, degree is the hydrochloric acid of 2-20%, and degree is the potassium hydrogen peroxymonosulfate of 5-25%, degree is the fatty alcohol-polyoxyethylene ether of 0.1-1%, and all the other are water.
Comprise degree and be 20% sulfuric acid, degree is 3% hydrochloric acid, and degree is 20% potassium hydrogen peroxymonosulfate, and degree is 0.2% fatty alcohol-polyoxyethylene ether, and all the other are water.
Compared with prior art, beneficial effect of the present invention is:
1. rust cleaning activator solution of the present invention has been owing to having added fatty alcohol-polyoxyethylene ether, thereby makes solution have lower acid gas evaporation rate, injures little to use equipment and operating personnel.
2. suitability is wide, and the zone of oxidation that is fit to the material surfaces such as iron, nickel, copper, stainless steel is removed.
3. the rust cleaning activating velocity is fast, is applicable to require to remove fast the High-speed Electric plate wire of zone of oxidation; When low to the rust cleaning rate request, can suitably reduce the concentration of rust cleaning activator;
In addition, the present invention also provides a kind of compound method of the activator solution that eliminates rust, and comprises successively:
The first step: add the pure water of 1000L in container, then add the sulfuric acid of 400L, stirred 10 minutes, mix rear cooling;
Second step: during lower than 35 ℃, add the potassium hydrogen peroxymonosulfate of 400kg when solution temperature, stirred 60 minutes;
The 3rd step: after described potassium hydrogen peroxymonosulfate dissolves fully, then add the hydrochloric acid of 60kg, stir and solution was mixed in 10 minutes;
The 4th step: add the fatty alcohol-polyoxyethylene ether of 4kg, then add pure water to the required liquid level of solution, stirred 30 minutes, at last solution is distributed into small packages.
At last, the present invention also provides a kind of using method of described rust cleaning activator solution, it is characterized in that: pending workpiece is carried out oil removal treatment in advance, then soak in rust cleaning activator at room temperature, treat that zone of oxidation removes totally fully, taking-up, washing is clean, then carries out the operation of later process.
Embodiment
The invention provides a kind of activator solution that eliminates rust and comprise the sulfuric acid that degree is 15-40%, degree is the hydrochloric acid of 2-20%, degree is the potassium hydrogen peroxymonosulfate of 5-25%, and degree is the fatty alcohol-polyoxyethylene ether of 0.1-1%, and all the other are water.
Embodiment:
It is 20% sulfuric acid that rust cleaning activator solution of the present invention comprises degree, and degree is 3% hydrochloric acid, and degree is 20% potassium hydrogen peroxymonosulfate, and degree is 0.2% fatty alcohol-polyoxyethylene ether, and all the other are water.
Rust cleaning activator of the present invention is mainly take sulfuric acid as the basis, add hydrochloric acid to increase the rust cleaning activator to the dissolving power of zone of oxidation, because hydrochloric acid is a kind of reductive acid, and its metallic salt is mostly soluble in water, so can coordinate with sulfuric acid the dissolving power that promotes zone of oxidation.Add fatty alcohol-polyoxyethylene ether to improve the ability of the penetrating power of rust cleaning activator in zone of oxidation and the volatilization of inhibition acid gas: fatty alcohol-polyoxyethylene ether has the wettability that increases the metallic surface, make the rust cleaning activator can better enter into the inside of loose zone of oxidation and the place, dead angle of workpiece, make the removal of zone of oxidation more comprehensively; Fatty alcohol-polyoxyethylene ether produces a small amount of foam coverage on the surface of rust cleaning activator in the use procedure of rust cleaning activator, suppress acid gas and volatilize in air, and airborne acid gas concentration is reduced, and slows down using the corrosion of equipment.Add potassium hydrogen peroxymonosulfate to improve the dissolution rate of activator to zone of oxidation that eliminate rust: potassium hydrogen peroxymonosulfate easily discharges the oxygen of status nascendi in sour environment, the oxidisability of rust cleaning activator is strengthened, accelerated the dissolution rate of rust cleaning activator to the oxidation on metal surface layer in the dissolving that promotes metal in the rust cleaning activator.
In addition, the present invention also provides a kind of compound method of the activator solution that eliminates rust, and comprises successively:
The first step: add the pure water of 1000L in container, then add the sulfuric acid of 400L, stirred 10 minutes, mix rear cooling;
Second step: during lower than 35 ℃, add the potassium hydrogen peroxymonosulfate of 400kg when solution temperature, stirred 60 minutes;
The 3rd step: after described potassium hydrogen peroxymonosulfate dissolves fully, then add the hydrochloric acid of 60kg, stir and solution was mixed in 10 minutes;
The 4th step: add the fatty alcohol-polyoxyethylene ether of 4kg, then add pure water to the required liquid level of solution, stirred 30 minutes, at last solution is distributed into small packages.
Simultaneously, the present invention also provides a kind of using method of described rust cleaning activator solution, it is characterized in that: pending workpiece is carried out oil removal treatment in advance, then soak in rust cleaning activator at room temperature, treat that zone of oxidation removes totally fully, taking-up, washing is clean, then carries out the operation of later process.
Use when of the present invention as lower to the rust cleaning rate request, can suitably reduce the concentration of rust cleaning activator.
The above is only better embodiment of the present invention; protection scope of the present invention is not limited with above-mentioned embodiment; as long as the equivalence that those of ordinary skills do according to disclosed content is modified or changed, all should include in the protection domain of putting down in writing in claims.
