Embodiment Construction

[0027] Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] The invention provides a technical solution: a recycling process of waste plastic electroplating parts. The recycling process of waste plastic electroplating parts is to use chemical solution to dissolve and separate the metal or alloy on the surface of plastic electroplating parts, and to regenerate the metal. Specifically The operation is as follows:

[0029] The first step: cleaning and removing impurities of raw materials

[0030] Put the waste plastic electroplating parts into the cleaning device for cleaning, and then dewater and dry the waste plastic electroplating parts after cleaning;

[0031] The second step: crushing of raw materials

[0032] Send the cleaned and dried waste plastic electroplating parts into the crusher for crushing, screeni...

Abstract

The invention discloses a waste plastic electroplated piece recycling technology. According to the waste plastic electroplated piece recycling technology, a chemical solution is utilized for dissolving and separating metal or an alloy on the surface of a plastic electroplated piece, and the metal regeneration machining technology is conducted. According to the waste plastic electroplated piece recycling technology, hydrogen peroxide with the concentration proportion being 4%-6% and sulfuric acid with the concentration proportion being 15%-20% are adopted, deplating liquid formed through mixingmatching of the hydrogen peroxide and the sulfuric acid according to the proportion of 1:5 is used for conducting deplating treatment on the plastic electroplated piece surface metal, it can be ensured that the plastic electroplated piece surface metal layer is removed and corrosion damage cannot be caused to a plastic base body, and integrity of the plastic base body is guaranteed. Compared witha traditional technology, the deplating effect of the nitric acid and sulfuric acid mixed solution is utilized, deplating is more sufficient through a hydrogen peroxide deplating method, and the problem that metal is mixed on the plastic surface is solved and commonly happens in the traditional deplating technology.

Description

technical field [0001] The invention relates to the technical field of electroplating parts recycling technology, in particular to a recycling technology of waste plastic electroplating parts. Background technique [0002] The combination of metal and plastic makes it have many characteristics and is widely used, especially the ABS plastic electroplating parts. The annual output in China is about 50,000 tons. With a large amount of imports, the annual consumption is about 100,000 tons or more. Therefore, for its Recycling and harmless treatment of waste products are very important. At present, in the process of processing waste electroplated plastics in China, chemical deplating is mainly used. After the waste electroplated plastics are crushed with a crushing machine, a mixture of nitric acid and sulfuric acid is used to make Metals such as copper and nickel on the surface of waste electroplated plastics are dissolved, and the insolubles are washed to obtain pure plastics, ...
