Description
Technical field
The present invention relates to industry cleaning link field, especially a kind of environmentally friendly nitre groove agent, for substituting nitric acid, to chemical nickel plating groove
Cleaning maintenance is carried out, removes the nickel slag of deposition sedimentation in chemical nickel plating groove.
Background technology
The history of chemical nickel plating, ofer short duration, it is only the beginning of the eighties at the end of the seventies that it, which is really applied to industry, abroad.
1844, A.Wurtz had found that metallic nickel can be reduced from the aqueous solution of nickel salts and is deposited by hypophosphites.1944
Year, the discovery of the A.Brenner and G.Riddell of National Bureau of Standards, have understood the catalysis characteristics for forming coating, find
The method of the non-powdered nickel of deposition.
Nowadays the development of nearly 40 years is passed through, chemical nickel plating has become very ripe industrial surface treatment technology,
Each industrial department is widely used.The chemical nickel plating industrialized production of China is started late, but development in recent years
It is very rapid.The statistics published an article according to the 5th chemical plating annual meeting just You300Duo Jia producers, but this numeral should be pole
For what is guarded.By inference domestic annual chemical nickel plating market total scale should at 30,000,000,000 yuan or so, and with annual 10%~
15% speed increases.
Chemical nickel plating industrialization is very ripe, and is widely used in each department.But nickel bath is clear
Clean maintenance but always without obvious progress, still continues to use nitric acid and deposited nickel layer in groove and nickel slag is cleaned even to this day.By inference
Domestic annual chemical nickel plating groove carries out the cleaning maintenance of nitre groove with nitric acid, and the nitric acid used is up to as many as 1,500,000 tons.And nitric acid is one
Kind strong oxidizing property, the non-volatile inorganic acid of severe corrosive.It during nitric acid use, can volatilize to form acid mist, pollute air；It can divide
Solution forms nitrogen dioxide tobacco, and nitric oxide spirit poison gas；Touch skin meeting third-degree burn and form scar, to execute-in-place people
Member's personal safety forms hidden danger；And waste water contains the total nitrogen of high concentration.It is domestic by inference to use the nitric acid produced after nitric acid nitre groove
Waste liquid and nitrogenous flushing water, annual discharge capacity are about 9,000,000 tons, cause the serious pollution of water resource.
The content of the invention

Wherein：The complexing agent is ethylenediamine tetra-acetic acid, vulcanized sodium, citric acid, tartaric acid, oxalic acid, propyl disulfide, sulphur
At least one of guanidine-acetic acid；The stabilizer is sodium metasilicate, magnesium silicate, fatty acid magnesium salt, polyacrylamide, malic acid, lemon
At least one of lemon acid sodium；The corrosion inhibiter is mercapto benzothiazole, methylbenzotriazole, four nitrogen of 1- phenyl -5- sulfydryls
At least one of azoles, silicate, molybdate, tungstates.
Advantages of the present invention and beneficial effect：
1st, substitute nitric acid with sulfuric acid and its mate-assist thing and cleaning maintenance is carried out to chemical nickel plating equipment, reduce because using nitre
The discharge of exhaust emission and nitrogenous effluent caused by sour nitre groove；
2nd, the present invention is sulfuric acid system nitre groove cleaning maintenance medicament, nontoxic, pollution-free, nonflammable, non-explosive, meet the world
Various countries' environmental protection standard and inlet and outlet require.
