Why does the stainless steel color decorative plate have color differences?
According to reports, most of the titanium plating furnaces in metal material factories are basically semi-automatic vacuum titanium plating furnaces. In an effort to reduce production costs, many manufacturers continue to speed up the production process to achieve higher yields; as a result, films are getting thinner and furnace hours are reduced from 1 hour to 10 minutes or less. At the same time, due to the short working time of the titanium plating furnace, the technical requirements for voltage, current, and gas uniformity are correspondingly reduced and are unstable. This is prone to adverse consequences, such as reduced adhesion between the color film and the stainless steel surface, uneven color, and eventually leads to the color difference of the stainless steel plate, or even the paint film peeling off. On the other hand, the traditional water-plated stainless steel black titanium plate also has the problems of too short current, voltage, and working time, which is similar to vacuum plating.
If the color film on the surface of the stainless steel color decorative plate is too thin, after the product is formed or used, it will also cause local, irregular, and irregular color changes under the chemical reaction of temperature, humidity, and even contact with general chemical raw materials. Time cannot be predicted.
