Description
Technical field
The present invention relates to chemical nickel plating industry, particularly relate to a kind of large-scale steel cylinder chemical nickel plating method and device thereof.
Background technology
The plating solution of chemical nickel plating is generally main salt with single nickel salt, nickelous acetate etc., and hypophosphite, sodium borohydride, borine, hydrazine etc. are reductive agent, then add various auxiliary agent.Operation is carried out in acidic solution at 90 DEG C or the neutral solution close to normal temperature, basic solution.The large class of chemical plating nickel-phosphorus, chemical nickel plating-boron two is divided into use the difference of reductive agent.Coating homogeneity, solidity to corrosion, hardness, weldability, magnetic, ornamental on all demonstrate superiority.
Without extraneous electricity, by means of the method for redoxomorphism at deposited on silicon one deck nickel of metallic article.For improving corrosion stability and wear resistance, increase gloss and attractive in appearance.Be suitable for the bright nickel plating of the finding of tubulose or complex contour, need not again through polishing.Generally plated product is immersed in the mixing solutions that is made into single nickel salt, sodium dihydric hypophosphite, sodium acetate and boric acid, change under certain acidity and temperature, nickel ion in solution is reduced to atom by sodium dihydric hypophosphite and is deposited on article surface, forms the nickel coating of careful light.Steel piece can directly nickel plating.Tin, copper and copper alloy product first will be contacted with its 1-3 minute on the surface, to accelerate chemical nickel plating with aluminium flake.
It is carry out electroless plating by being placed in coating bath that traditional steel cylinder carries out inwall chemical nickel plating, main flow is electrochemical deoiling → washing → pickling → washing → chemical nickel plating → washing → closed → washing → oven dry, whole Ni-Speed needs after a groove process, transfer to a rear groove and processes, and carries out successively according to technical process.But when needs process large-scale steel cylinder, Large Steel bottle is long-pending large, and weight is large, and one is do not have so large coating bath, two is that weight is not easy to too greatly carrying, can strengthen the labour intensity of operator.
