The application of manganese sulfate monohydrate in brush plating

The technology and equipment of brush plating is simple, flexible and economic, which is widely applied in large molds’ manufacturing and repairation. The key of brush plating technology is the brush plating solution formula that may commonly contain nickel or manganese sulfate and other contents.

The commonly used brush plating solution in mold repairation
Formula One: special nickel

Nickel sulfate 395~397 g/L, sodium chloride 14~ 16g/L, acetic acid 68~70g/L, hydrochloride 20~28 g/L.

Formula Two: nickel - D tungsten alloy plating solution

Nickel sulfate 395 g/L, sodium tungstate 23 g/L, boric acid 31 g/L, citric acid 42 g/L, Cobalt sulfate 2 g/L, anhydrous sodium sulfate 6.5 g/L, magnesium sulfate 2 g/L, manganese sulfate monohydrate 2 g/L, acetic acid 20 ml/L, formic acid 35 ml/L, sodium fluoride 5 g/L, sodium dodecyl sulfate 0.01 ~ 0.001 g/L.

Plated through the brush plating solution with nickel sulfate, manganese sulfate, the coating of plating has good hardness, wear resistance and oxidation resistance. After the repairation of the technology, the service life of all kinds of mould can generally be increased by 20% to 200%.
