Plastic plating-electroless nickel plating solution-main salt.
Huizhou Boluo Tenglong Technology Co., Ltd. serves you wholeheartedly! Mainly engaged in plastic hydroelectroplating processing, with plastic injection molding processing, mold processing and so on! .
Main salt.
The main salts in electroless nickel plating solution are nickel salts, such as nickel sulfate, nickel chloride, nickel acetate, etc., which provide nickel separation needed in the process of electroless plating. Nickel chloride was used as the main salt in the early stage, but it is no longer used because the existence of chloride ion will not only reduce the corrosion resistance of the coating, but also produce tensile stress. Compared with nickel sulfate, the beneficial contribution of using nickel acetate as the main salt to the properties of the coating is offset because of its high price. In fact, the most ideal source of nickel ion should be nickel hypophosphite, which will not accumulate a large amount of sulfate in the bath, nor will it be brought into sodium ion by adding sodium hypophosphite in use, which can not be applied industrially because of its price. At present, nickel sulfate is the most widely used. Due to the slightly different manufacturing process, there are two kinds of nickel sulfate with crystal water. Because nickel sulfate is the main salt with a large amount, it has to be continuously added in the plating, and the impurity elements will accumulate in the bath, resulting in a decrease in the plating rate, shorten the service life, and affect the performance of the coating, especially the corrosion resistance. Therefore, when purchasing nickel sulfate, we should strive to provide reliable composition test list to ensure the stable quality of each batch, especially pay attention to the control of zinc and heavy metal elements which are harmful to the plating bath.
