Pickling copper polishing additive MS0309 Overview: This product is made by our company with well-known institutions of higher learning long-term research and development of proprietary products for the current worldwide resistance to salt spray for copper passivation has no lack of long points, breaking the current market traditional recipes, there has never been bold synthesis of new materials and new technology. Currently in copper passivation has reached the world advanced level. With a chromic acid, and benzene handle traditional system passivation unparalleled results. For after copper chemical polishing, electrolytic polishing, mechanical polishing and other surface treatment, immediately passivation, the surface layer is converted to the active metal inert to the metal surface, can effectively prevent the oxidation of copper surface, maintain the character after polishing. Suitable materials: suitable for all copper and copper alloys Keyword Guide: US Beishi brand copper pickling brightener, smokeless polished copper brightener, polished copper efficient additives and to name + copper pickling throw agent (such as pickling Dongguan copper polish) I. Introduction: This product is made of high quality imported surfactants, complexing agents and fog inhibitor compound formed, add this product to the polishing solution containing sulfuric acid system, it is possible increase the polishing rate of copper pieces, flatness and brightness. Compared to the traditional three-acid products, the product overcome similar products are not universal, easy to produce tobacco, poor stability defects. Therefore, this product is an alternative to the traditional three-acid products better choice. Second, the product features: 1, a light speed, stable solution: 20 seconds fast light, pharmaceutical stability does not decompose 2, environmentally friendly: no "tobacco", improve the working environment 3, versatility: can basically meet the market 95% Pickling copper polishing using 4, low cost: The cost of the process is only three acid process 40% -60% Third, slotted and use: first take, such as sulfuric acid and sodium nitrate measurement components dissolved in pure water metering, Note that the temperature should not exceed 50 degrees. Then added to the product of 2-3% (to take maximum copper difference). Stir to cool to room temperature can be used. The best advice when using a temperature of 40 to 45 degrees, keeping removed after 20 seconds to 2 minutes, then rinse with water. Polishing time by the extent of surface oxidation of copper to decide. Fourth, note: 1, in the pickling, the workpiece should be appropriate in order to avoid overlap jitter between the workpiece, but not before stirring to form a uniform foam surface is not otherwise easily lead to uneven polishing 2, should as soon as possible after pickling Wash the workpiece with water, such as the case is not ideal brightness pickling may be repeated until qualified 3, pickling if the workpiece has a complicated shape like a blind hole, it is recommended to use a concentration of 0.5-1% of sodium hydroxide solution and After treatment, before subsequent passivation. In order to avoid the pickling liquid into the passivating agent caused the failure. Acid pickling polishing before polishing five powerful advantage Kai Union brand copper passivation solution :: 1, patented formula, patented product, market traditional products can not match. 2, between the simple operation, without complex equipment, can be used at room temperature. 3, efficient: passivation time is short, and high efficiency. 4, the high degree of oxidation gasification, salt spray test is better than chromate passivation. 5, safety and environmental protection, without containing harmful substances, odorless, water-based products. Six, Kay UNITA to solve your problem: First, do not need professional equipment, no professional staff, to complete two simple soaking, no complicated process requirements Third, you can re-use, low-cost four, environmentally friendly, safe operation, absolutely no odor seven, Kay Union Service: We will delivery technicians come to guide the operation of eight, Kay National League divisions: Suzhou, Chongqing, Dongguan, Zhongshan, Foshan, Taizhou, Ningbo Cixi
