Clothing fake more and more serious, sometimes true and false clothing is difficult to distinguish through the fabric, which must look at clothing accessories from a small place, the real clothing accessories are mostly exquisite workmanship, with its own brand LOGO features, such as buttons, many Clothing is engraved or printed with the logo of the brand, and if buttons work rough, or large quantities of clothes use the same buttons and other accessories, it may be fake.
"ABS" is a conductive layer that can be coated with nickel and chromium metal coats on the buttons. After the roughening, chemical methods such as depositing stannous chloride, silver nitrate, and copper sulfate into the micropores on the surface of the eroded plastic product can be used to make the surface of the plastic adhere to a conductive metal film. However, when you hold them by hand, there is no impression of the texture: how is it so light? In fact, this beautiful "metal" button is not metal but plastic. In fact, plating metal coats on plastics is not an easy task. Of course, in the future development, there are new types of substitute materials that are not impossible. And the plastic is afraid of heat, and the temperature is high and it is easy to melt. Therefore, it is not possible to directly plate the metal on the surface of the plastic product. We usually go to the shops to see the beautiful buttons in a box of small department stores. Some of them are glittering, some are silver, and they are beautiful and luxurious. Once this plastic hits chromic acid, the surface will be eroded, resulting in many micropores (coarsening in the electroplating industry). According to current statistics, plastics used for electroplating are still limited to "ABS". Because the coefficient of expansion of plastics and metals is not the same; plastic is also an insulator, and it is difficult for ions to enter.
Today is an era of high-tech development. Metals can be electroplated, but have you seen that plastics can also be electroplated? The answer is yes. Through many experiments, people finally invented a new type of plastic called "ABS." Gold and silver luxury coats on their surface are chemically plated.
