Chemical nickel plating device and chemical nickel plating method

Abstract

The invention provides a chemical nickel plating device and a chemical nickel plating method. The chemical nickel plating device comprises a groove body, an air compressor and a circulating filter, wherein the groove body is internally provided with an electrical heating pipe, and the electrical heating pipe is connected with a temperature controller arranged outside the groove body; the air compressor is connected with an air pipe, and the tail end of the air pipe extends into the bottom of the groove body; and two ends of the circulating filter are connected with a liquid inlet pipe and a liquid outlet pipe, the liquid inlet pipe is communicated with the bottom of the groove body, and the liquid outlet pipe extends into the groove body. According to the chemical nickel plating device, the groove body is made from high-purity polypropylene, so that the defects of poor heat conductivity and poor groove body strength of the groove body are prevented; no metal substance contacts with a chemical nickel plating solution in an integral nickel plating process, so that nickel and phosphorus are prevented from being deposited in the groove body and on other parts of the chemical nickel plating device; and an obtained plating layer is bright, smooth and exquisite without pocking marks due to the effect of air stirring and circulating filtration.

Description

technical field [0001] The invention belongs to the technical field of electroless nickel plating, and relates to an electroless nickel plating device mainly used in the semi-industrial test of the chemical nickel plating process and an electroless nickel plating method using the device. Background technique [0002] In the electroless nickel plating test, the nickel plating tank generally adopts acid-resistant enamel tank, lined with soft PVC steel tank, heat-resistant and acid-resistant ceramic tank and stainless steel tank body, while acid-resistant enamel tank, lined with soft PVC steel tank, heat-resistant and acid-resistant ceramic tank Both have the shortcomings of poor thermal conductivity and tank strength. Although the effect of stainless steel tank is good, it is necessary to apply a voltage value to the stainless steel tank and the chemical nickel plating solution to prevent the tank from being plated with chemical nickel, which virtually increases the cost of che...
