Before plating or coating, the metal surface needs to be thoroughly treated to remove grease, impurities, rust and create an optimal adhesion base for the coating.<\/p>\n
The selection of appropriate chemicals is crucial for achieving optimal results in metal surface treatment.<\/p>\n
Mechanical Grinding \u2013 A traditional but effective cleaning step<\/strong><\/p>\n This is a method of using abrasive materials to conduct rough grinding and fine grinding of metal surfaces. This process eliminates triple via, flattens the surface, and adds gloss to the product before plating or painting.<\/p>\n Mechanical grinding is still widely used in the mechanical engineering industry, stainless steel processing, steel and industrial components.<\/p>\n Ball Rotation \u2013 The Ultimate Solution for Small Parts<\/strong><\/p>\n For parts with small sizes or complex shapes that are difficult to handle with conventional grinding methods, dry ball turning or wet ball turning technique is considered the right choice.<\/p>\n This method helps the metal surface achieve high uniformity, increase aesthetics and improve stain resistance.<\/p>\n Chemical Treatment \u2013 The “Heart” of Surface Treatment Technology<\/strong><\/p>\n This is the most important method in modern surface treatment processes. Through chemical or electrochemical reactions, the grease, oxide and rust layer on the metal surface will be completely removed before plating or coating.<\/p>\n Common techniques include:<\/em><\/strong><\/p>\n As a result, the product has higher corrosion resistance, a more durable coating, and an increased service life in harsh industrial environments.<\/p>\n Along with the treatment technology is a specialized chemical system \u2013 a factor that directly determines the operational efficiency and quality of the finished product.<\/p>\n Alkaline Degreasing Chemicals<\/em><\/strong><\/p>\n This is a line of chemicals commonly used to remove grease and dirt from the surface of steel, iron, aluminum, copper or zinc.<\/p>\n Depending on the type of metal and the level of contamination, you can choose a strong, medium, or light alkaline solution to ensure optimal cleaning efficiency without affecting the metal substrate.<\/p>\n Acid Degreasing Chemicals<\/em><\/strong><\/p>\n Acid degreasing solutions are commonly used for galvanized steel and surfaces that require high cleanability but still ensure that they do not damage the plating.<\/p>\n This chemical is particularly effective in treating industrial oils that have been on metal surfaces for a long time.<\/p>\n Aluminum Removal Chemicals<\/em><\/strong><\/p>\n In the aluminum and aluminum alloy industry, aluminum cleaning chemicals help clean, regenerate surfaces and increase adhesion to plating or backcoating.<\/p>\n Zinc Phosphate \u2013 An Effective Anti-Corrosion Solution<\/em><\/strong><\/p>\n Zinc phosphate is one of the most popular pretreatment technologies today, especially in the powder coating industry.<\/p>\n The phosphate layer created on the metal surface is capable of:<\/p>\n Chromium Chemistry and Chrome Replacement Technology(VI)<\/em><\/strong><\/p>\n For many years, chromium has been a popular chemical in the plating industry thanks to its superior ability to create an anti-corrosion passivation layer. However, the current global trend is shifting sharply towards chrome(VI)-free solutions to meet stringent environmental standards.<\/p>\n This is also a field that many chemical technology enterprises are focusing on research and development.<\/p>\n In the context of the industry’s increasing demands on surface quality and environmental standards, DK Chemicals<\/a> is becoming one of the units chosen by many mechanical, steel and aluminum enterprises in Vietnam.<\/p>\n DK Chemicals specializes in providing a wide range of metal surface treatment chemicals such as:<\/p>\n Not only providing products, the business also supports technical advice, optimizing operating processes and suitable treatment solutions for each type of material and production line.<\/p>\n PrimeCoat\u00ae and PreCoat\u00ae \u2013 Non-chrome surface treatment trends(VI)<\/strong><\/p>\n One of the highlights at DK Chemicals is the provision of advanced surface treatment solutions from the PrimeCoat\u00ae and PreCoat\u00ae brands\u2014technologies that stand out in the field of chrome(VI) non-metal treatment.<\/p>\n These product lines are developed according to the trend:<\/p>\n In particular, the flexible modular processing system allows businesses to customize chemical solutions according to each specific production line, helping to optimize efficiency and operating costs.<\/p>\n The inevitable trend of modern industry<\/strong><\/p>\n Along with the development of the steel, mechanical and fabrication industries, metal surface treatment is becoming a field with a very fast technological innovation rate.<\/p>\n From traditional processing methods to chrome(VI)-free green chemical technology, the market is witnessing a drastic shift towards higher performance, more sustainability, and more environmentally friendly.<\/p>\n In that trend, enterprises providing comprehensive solutions such as DK Chemicals<\/a> are expected to play an important role in supporting the Vietnamese industry to improve product quality and increase competitiveness in the international market.<\/p>\n Explore Some Surface Treatment Chemicals Here<\/strong>:\u00a0https:\/\/dk-chemicals.vn\/<\/a><\/p>\n\n
