Core tip: of all plastics, PP plastics are also Electroplated Plastics After electroplated, PP plastics have excellent wear resistance, corrosion resistance and surface hardness, and greatly improve the commodity attractiveness of PP products It also makes PP plastic products more and more widely used Due to the addition of fillers, the dimensional accuracy, temperature resistance and applicability of Electroplated Plastics are improved The coarsening process is also simpler The electroplating grade PP plastics can be coarsened by ordinary process, and only the coarsening temperature needs to be increased The mechanism of coarsening is to make use of the strong oxidation of the coarsening liquid to make the filler Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Paint Home News: in all plastics, PP plastics are electroplated plastics After electroplated, PP plastics have excellent wear resistance, corrosion resistance and surface hardness, and greatly improve the commodity attractiveness of PP products It also makes PP plastic products more and more widely used Due to the addition of fillers, the dimensional accuracy, temperature resistance and applicability of Electroplated Plastics are improved The coarsening process is also simpler The electroplating grade PP plastics can be coarsened by ordinary process, and only the coarsening temperature needs to be increased The mechanism of coarsening is to use the strong oxidation of coarsening liquid to make the filler dissolve from the surface structure and make the surface micro roughening This is similar to roughening on ABS plastic surfaces Due to the poor hydrophilic material of PP plastics, the coarsened products should be turned frequently in the coarsening process, and can be taken out in the coarsening process for cleaning and coarsening repeatedly, the effect will be better, of course, this is only suitable for complete manual operation The mechanism of coarsening is to use the strong oxidation of coarsening liquid to make the filler dissolve from the surface structure and make the surface micro roughening Due to the poor hydrophilicity of PP plastics, even if the oil is fully removed, it is inevitable that the parts with complex shape are not easy to be hydrophilic These parts are easy to be missed in electroless plating In order to prevent this kind of situation, it is necessary to turn the coarsened products frequently during the coarsening process In addition, the products can be taken out for cleaning and then coarsening in the coarsening process, so that the coarsening can be repeated repeatedly, and the effect will be better, of course, this is only applicable to complete manual operation The specific electroplating process of electroplating grade PP plastics: the electroplating process of electroplating grade PP plastics is as follows: degreasing, cleaning, neutralization with 5% sulfuric acid, cleaning, roughening, cleaning, sensitization, cleaning, palladium activation, cleaning, chemical nickel plating, cleaning and electroplating Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
