[0020] Example 1: Process flow of stainless electroplating

[0021] 1) Clean the product: put the product on a special hanger and clean it with ultrasonic waves a. Configure the cleaning solution. b. Heating the cleaning liquid to improve the cleaning effect (using environmentally friendly steam heating) the product is installed on the hanger and cleaned directly. c. Turn on the ultrasonic wave for 1 minute vibration treatment. d. Then wash it twice in clean water. Wash it once in pure water with conductivity ≤0.1μS. (Phosphating treatment is also required for steel products)

[0022] 2) Bottom processing:

[0023] a. Add 15% epoxy resin into the treatment tank, use a chemical pump to circulate to prevent precipitation, use a filter element to remove impurities and sediment, and keep the temperature of the bath above 20°C.

[0024] b. The product is installed on a conductive hanger and put into the treatment tank, so that the negative pole of the DC power supply is connec...

Abstract

The invention relates to a non-rust electroplating process which is characterized in that a base coating, a middle bright metal coating and a coloring protection coating (color-mixing UV (Ultraviolet) gloss oil) are sequentially made on the surface of a product from inside to outside by adopting a chemical method to treat the surface of the product. The non-rust electroplating process comprises the following steps of: (1) ultrasonic cleaning->cleaning with clear water->cleaning with pure water (phosphating is also carried out on iron and steel products); (2) treating the base coating: enabling a nonmetal coating to be evenly combined with the product under the effect of an electric field and then heating to make the coating solidify; (3) treating the middle coating: cleaning the product->spraying medicinal liquid on the product->cleaning the product->drying the product; and (4) treating the coloring protection coating (color-mixing UV gloss oil): dipping the product in color-mixing UV gloss oil, then baking for 2-3 minutes in an oven at 50 DEG C and finally carrying out UV irradiation with a certain intensity for 3-5 seconds to achieve the solidification effect.

Description

technical field [0001] The stainless electroplating process is mainly to treat the surface of the product through chemical methods, and then do the bottom coating, the bright metal coating in the middle and the colored protective coating (color-colored UV varnish) on the surface of the product from the inside to the outside. ). Background technique [0002] The similarity between the stainless electroplating of the present invention and the traditional electroplating technology is that a layer of protective or decorative coating is applied to the metal material (including some non-metallic materials). The traditional electroplating process will produce extremely serious pollution, and will discharge a large amount of acidic waste liquid containing heavy metals. In order to solve the problem of serious environmental pollution and high cost of traditional electroplating, a research and development team with entrepreneur Lin Ting, postdoctorate student at Osaka University in J...
