Problems solved by technology

At present, the electroplating of plastic pipe fittings is widely used in the market. The traditional electroplating of plastic pipe fittings, the existing process has poor applicability to plastic parts, resulting in a high proportion of product defects and scrapping; and the existing plastic pipe fittings are sprayed. In some cases, the outer walls at both ends are fixed, so that a small part of the outer walls at both ends is blocked, so that the spraying cannot be completed, and secondary processing is required later, and the spraying efficiency is low

Embodiment 1

[0029] see figure 1 , a process for improving the adsorption performance of active palladium on the surface of electroplating grade plastic parts, comprising a plastic substrate 10, comprising the following steps;

[0030] S1. Perform ultrasonic degreasing, high-temperature degreasing and water washing on the plastic base material 10. Here, wash twice to remove oil stains on the surface of the plastic base material 1, and then carry out pickling and water washing on the degreasing plastic base material 10 in sequence. , where it is washed three times with water to obtain the specified surface roughness; specifically, after the plastic substrate 10 is hung up with a hanger, it is put into the ultrasonic control box and the high-temperature water tank, and both stay for 40 seconds. Material 1 is degreased, and after degreasing, it is washed once in two groups of pools, and the water stays for 5 seconds; after that, the plastic base material 10 is put into a pickling pool with a ...

Abstract

The invention discloses a process and a device for improving the adsorption performance of active palladium on the surface of an electroplating-grade plastic part, and relates to the field of engineering plastic electroplating. The device comprises a plastic base material and the process comprises the following operation steps that S1, the plastic base material is subjected to ultrasonic oil removal, high-temperature oil removal and water washing, then oil stains on the surface of the plastic base material are removed, and the plastic base material subjected to oil removal is subjected to acid etching and water washing in sequence, so that the surface of the plastic base material is coarsened; and S2, the plastic base material is washed with water, ethidene diamine is added into a water pool to adjust the coarsened surface of the plastic base material, and therefore the adsorption efficiency of the active palladium on the surface of the plastic base material is improved. According to the process for improving the adsorption performance of the active palladium on the surface of the electroplating-grade plastic part, the surface of the coarsened plastic part is adjusted by adding the ethidene diamine with a certain concentration in a plastic electroplating pretreatment procedure in a washing manner, so that the adsorption efficiency of the active palladium on the surface of the plastic base material is improved, and the plastic leakage ratio of the plastic base material is reduced.

Description

Technical field: [0001] The invention relates to the field of engineering plastic electroplating, in particular to a process and a device for improving the adsorption performance of active palladium on the surface of electroplating-grade plastic parts. Background technique: [0002] Engineering plastics refer to plastics that can be used as engineering materials and replace metal manufacturing machine parts. They have the characteristics of high strength, good impact resistance, good heat resistance, high hardness and excellent aging resistance. They are widely used in industrial parts or shells. Production and processing of materials. At present, the electroplating of plastic pipe fittings is widely used in the market. The traditional electroplating of plastic pipe fittings, the existing process has poor applicability to plastic parts, resulting in a high proportion of product defects and scrapping; and the existing plastic pipe fittings are sprayed. In some cases, the out...
