This type of polymer includes formaldehyde polymer, elastic polyurethane, and conductive carbon black, The key is that this carbon black has a lower structural value (absorption) and larger particle size compared to the carbon black used in these compositions so far The further development of low surface is the development of directly conductive polymers. This conductive plastic was accidentally discovered during experimental operation errors. That was one day in 1970, when Professor Shirakawa of Tsukuba University in Japan was guiding students in an experiment to produce polyacetylene using ethylene gas, they mistakenly added a catalyst 1000 times more than the actual amount needed to the reagent, and the result was not the expected black polyacetylene powder containing carbon based long chains It is a shiny silver plastic film. Later, when studying this plastic film with two Americans, Shirakawa found that adding iodine to the film could actually conduct electricity, and the conductivity increased by 30 million times. Nevertheless, its conductivity is only equivalent to that of metal lead, or IX of copper and silver. Afterwards, people began to study this conductive plastic.

Subsequent studies showed that, in addition to polyacetylene, some high molecular polymers such as polyphenylene sulfide, polypyrrole, Polythiophene and polythiazole can also become conductive plastics after adding dopants. On this basis, people have made a batch of polymers with conductivity equivalent to silver and copper, and called them organic metals or synthetic metals.

With the rapid development of modern industrial technology, especially the astonishing progress of modern electronic technology represented by the international internet and global mobile communication, it is believed that a new generation of directly plastic plated products will be developed, as this is already an urgent market demand. This need is a powerful driving force for technological progress.

The poor performance of the adhesive parts is as follows: water lines; Air pattern. The effect after electroplating is that it is still clearly visible after electroplating, as the electroplating itself has a thin coating (2-30um), which is difficult to achieve solely by electroplating coverage.

The manifestation of defective rubber parts is batch peak. The effect after electroplating is that the electroplating layer still accumulates, which can easily cause scratches and affect assembly.

The poor performance of the adhesive part is: adhesive excrement. The effect after electroplating is that it still cannot be covered, affecting the appearance.

The poor performance of the adhesive parts is as follows: embossing/blistering. The effect after electroplating is: foaming after electroplating.

The poor performance of the adhesive parts is as follows: adhesive wire/plastic shavings. The effect of electroplating is that it forms metal chips after electroplating, which affects assembly and easily damages the electroplating bath solution.

The poor performance of the rubber component is as follows: collision/scratch. The effect after electroplating is that it becomes more pronounced and affects the appearance.

The poor performance of the adhesive is manifested as impurities. The effect of electroplating is that it can cause sand particles, blistering, and leakage, affecting the appearance.

The poor performance of the adhesive is manifested as shrinkage holes. The effect after electroplating is that it is easy to hide the electroplating solution, which affects the composition of the electroplating cylinder fluid and leads to missed plating of the workpiece.

The manifestation of defective adhesive parts is the use of release agents. The effect after electroplating is that it is easy to cause plating leakage, and the bonding force of the plated parts is poor, with oil stains.

The poor performance of the adhesive part is manifested as excessive material at the nozzle. The effect after electroplating is that it is easy to cause pitting, and the plated parts may miss plating, resulting in poor adhesion. The maximum amount of nozzle material should not exceed 30%.

The poor performance of the adhesive parts is manifested as mold printing, spark marks, and drag marks. The effect after electroplating is that it becomes more pronounced and affects the appearance.

Matte corrosion lines of electroplated parts: The thickness of surface corrosion lines should be consistent, especially for semi gloss chromium products. If the corrosion lines are fine, there will be no matte effect.

Setting of hanging positions for electroplated parts: Without appropriate hanging positions, it is easy to cause deformation, and poor connection between parts and water nozzles can cause poor current flow, resulting in yellowing and plating leakage.

The material composition of electroplated parts: Electroplated grade ABS is the best, or ordinary ABS can be used. The ingredients should be brand new, and no color powder should be added.

Packaging method for electroplated parts: The preferred method is to use a single blister box for packaging, followed by a single set of PE bags. Large items should be wrapped with inner cotton sheets and outer bubble bags.
