glasses electroplating
glasses electroplating
There are two kinds of electroplating,
one is water electroplating, also known as electroless plating,
one is vacuum plating, physical and meteorological deposition reaction.
In the past, some local governments have suspended production because of heavy metal pollution caused by sewage.The latter has no pollution to the environment, is the future development trend.European countries now have strict standards for heavy metal content in products.Because heavy metals are bad for you.Not only glasses, but also other export products under strict control.
Now the glasses frame is mainly vacuum plated titanium, (titanium oxide, titanium nitride, etc.) chromium plating, zirconium plating, aluminum plating, gold plating, silver plating and so on can be plated with a variety of colors: for example, red, yellow, blue, green, purple, gold, silver, gray and so on, these are completed in the plating film.The film coating is bright in color, which greatly improves the grade of the product.
The disadvantage is that the process has a high requirement for operators, and the development of products needs talents and funds, because the coating process is also in the research and development stage.
The basic processes of eyeglass electroplating are as follows: bright nickel electroplating, gun black electroplating, gold-imitation electroplating, cu-tin electroplating (also now called nickel-free electroplating). Related accessories are silver plating, silver plating, gold plating and so on.
Electrophoretic coating on the electroplating of the metal spectacle frame is quite successful.However, there are many new problems. For example, some countries in Europe have banned the use of nickel or nickel alloy in metal glasses frames.Gold-silver alloy and copper-tin alloy coatings are widely used as substitutes for nickel and nickel alloy coatings.However, the electroplating of these alloys itself has no good corrosion resistance, so high-performance electrophoretic coating must be adopted to meet the performance requirements of surface treatment of metal spectacle frames.
Titanium is more and more popular in the application of light weight and high corrosion resistance in the metal spectacle frame.And titanium material has good corrosion resistance, electrophoretic coating can be used directly after the polishing surface treatment, high performance of electrophoretic coating not only can meet the performance and appearance requirements of titanium metal frames, and greatly reduces the cost of surface treatment of titanium frames, thus can promote the popularity of titanium frames and thoroughly solve the problem of nickel metal frames without stripping.
