Description
Technical Field
The invention relates to the technical field of nickel electroplating, in particular to a powder coating formula with nickel electroplating effect and a production processing method.
Background
Electroplated nickel is mainly used as a protective decorative coating. The nickel plating layer is a cathodic plating layer with respect to the iron substrate. The porosity is high, so that a copper plating layer is used as a bottom layer or multiple layers of nickel plating are adopted. Nickel coatings deposited from conventional nickel plating solutions are not bright, but are easily polished. A mirror-bright nickel layer can be obtained using certain brighteners. It is widely used in automobile, bicycle, clock, medical equipment, instrument and daily hardware, etc. Sulfate-chloride solutions containing a portion of the chloride, known as "watt" nickel baths, are most widely used in production. Paint (paint), which we commonly speak of as paint, is but one such. The coating is a liquid or solid material which can form a film under certain conditions and has the functions of protection, decoration or other special functions (insulation, rust prevention, mildew prevention, heat resistance and the like) when being coated on the surface of an object. Since the early coatings mostly used vegetable oils as the main raw material, they were also called paints. Synthetic resins have now replaced vegetable oils and are known as coatings. The coating is not liquid, and powder coating is a large category of coating. The paint belongs to organic chemical high molecular material, and the formed coating film belongs to high molecular compound type. According to the modern popular classification of chemical products, the coating belongs to fine chemical products. Modern coatings are gradually becoming a multifunctional engineering material, an important industry in the chemical industry.
