How to deal with the phosphor bronze tube oxidized to restore the original gloss, bright as a new mouth
Phosphor bronze pipes are widely used in industrial production and their artwork. Many phosphor bronze tubes have a certain degree of corrosion resistance, but they have little knowledge of their actual characteristics. Therefore, various oxidation and corrosion problems often occur during surface treatment, and the product quality cannot be guaranteed. . So how should the phosphor bronze tube be oxidized to repair the original gloss of the phosphor bronze tube and improve the quality of the product?
Phosphor bronze tube
According to the different oxidation levels of phosphor bronze tube products, I will introduce some solutions for everyone in detail below:
The surface layer of phosphor bronze tube is only slightly oxidized and discolored, and there is no serious gray-black oxide or verdigris. Under this condition, only the phosphor bronze tube must be immersed in an acid cleaning agent that eliminates phosphor bronze tube oxides. The oxide melts away and does not affect and etch the phosphor bronze tube substrate. However, many acidic cleaning agents will over-etch the phosphor bronze tube substrate. Therefore, it is very important to choose the cleaning agent (it is strongly recommended to use the copper cleaning agent MS0217 for corrosion resistance and environmental protection).
The surface layer of the phosphor bronze tube is more severely oxidized, with more serious gray-black oxide or patina; in this situation, it is difficult to achieve an ideal practical effect by cleaning only with a cleaning agent, because the erosion is more serious It affects the inside of the phosphor bronze tube sheet. After cleaning, there will still be an etched spot on the surface of the phosphor bronze tube, causing the overall actual effect to be uneven. At this time, you can choose to carry out grinding and polishing solutions: grinding and polishing, electro-polishing, and grinding and polishing include vibration grinding, magnetic grinding, and polishing treatment. Electro-polishing can choose the environmental protection and high-quality hydrogen peroxide management system. Polishing and polishing process ( Polishing agent MS0308-1, etc.). The actual effect of repairing the surface of the phosphor bronze tube to bling.
After the phosphor bronze tube is oxidized, the above solution can be used to restore the original gloss and brightness of the copper parts. The copper cleaner is an environmentally friendly cleaning agent. After cleaning and repairing the original gloss of copper parts, passivation treatment and maintenance must be carried out fade.
