Compared with mechanical polishing and electrochemical polishing, chemical polishing of brass does not need electricity and hanging tools. Therefore, it can polish the carved brass sheet with complex shape, and the production efficiency is high. The bright surface is obtained by chemical polishing, and the decorative effect and surface properties of copper and copper alloy are improved. Brass polish can quickly and effectively remove the oxide, burr, stain on the brass surface, so as to ensure the smooth polishing surface, and has a certain anti-oxidation effect.
Carving brass sheet chemical polish method: the use of the agent stock solution, can not bring water into the polishing liquid. No grease on the surface before polishing. Soak all the copper parts in the polishing liquid, soak for about 2 minutes to 4 minutes after removal, immediately rinse with water. Do not invest too much workpiece at one time, there should be a certain distance between the workpiece and the workpiece, do not overlap between the workpiece, and the polishing should be light from time to time to turn the workpiece, the purpose of uniform polishing. When used for a certain time, if it is found that the brightness of chemical polish decreases, it is necessary to add long-acting additives, 10 grams ~ 15 grams of long-acting additives per kilogram of polish, stir evenly before use. After the brass sheet is cleaned and air dried, the next process operation can be carried out, such as passivation and welding.
Carving brass sheet chemical polish not only has excellent reduction effect, in a short time can make the product take on a new look, after polishing the product is not easy to oxidation corrosion and other characteristics, but we need to pay attention to when using, chemical polishing machine is acidic, corrosive to the skin, handle gently, and wear rubber gloves. The dumping should be slow to prevent splashing on people. In case of contact with skin, rinse immediately with water. Use the stock solution, and avoid bringing water into the polishing solution during use. Before and after use should be sealed, do not expose to the sun, store in a cool ventilated place.
