Description
Technical field
The present invention relates to chemical nickel plating industry, relate in particular to a kind of large-scale steel cylinder chemical nickel plating method and device thereof.
Background technology
It is main salt that the plating solution of chemical nickel plating generally be take single nickel salt, nickelous acetate etc., and hypophosphite, sodium borohydride, borine, hydrazine etc. are reductive agent, then add various auxiliary agents.At the acidic solutions of 90 ℃ or in approaching the neutral solution, basic solution of normal temperature, carry out operation.To use the difference of reductive agent to be divided into chemical plating nickel-phosphorus, the large class of chemical nickel plating-boron two.Coating all demonstrates superiority in homogeneity, solidity to corrosion, hardness, weldability, magnetic, on ornamental.
Without extraneous electricity, borrow redoxomorphism on the surface of metallic article, to deposit the method for one deck nickel.Be used for improving corrosion stability and wear resistance, increase gloss and attractive in appearance.The bright nickel plating that is suitable for the finding of tubulose or complex contour, needn't be again through polishing.Generally plated product is immersed with in the mixing solutions that single nickel salt, sodium dihydric hypophosphite, sodium acetate and boric acid were made into, at certain acidity and temperature, change, nickel ion in solution is reduced to atom by sodium dihydric hypophosphite and is deposited on product surface, forms the nickel coating of careful light.Directly nickel plating of steel piece.Tin, copper and copper alloy product will first be contacted with the upper 1-3 minute in its surface with aluminium flake, to accelerate chemical nickel plating.
It is to carry out electroless plating by being placed in coating bath that traditional steel cylinder carries out inwall chemical nickel plating, main flow process is electrochemical deoiling → washing → pickling → washing → chemical nickel plating → washing → sealing → washing → oven dry, whole Ni-Speed need to be transferred to a rear groove and process from a groove is processed, and according to technical process, carries out successively.But when needs are processed large-scale steel cylinder, Large Steel bottle is long-pending large, and weight is large, the one, there is no so large coating bath, the 2nd, weight is not easy to too greatly carrying, can strengthen operator's labour intensity.
Summary of the invention
The technical assignment of technical problem to be solved by this invention and proposition is that prior art is improved, a kind of large-scale steel cylinder chemical nickel plating method and device thereof are provided, solve the problem that steel cylinder chemical nickel plating mode traditional in current technology is not easy to process the steel cylinder that volume is large, weight is large.
