(AOYANG Chief Engineer) to answer a variety of copper surface treatment problems 1, there is no substitute for the traditional pickling copper polishing liquid on the market European hello, consult your company's environmental copper polishing research and development achievements, the process is stable, has entered Mass production Consultant: Xiao Han Aoyou (Ouyang) Chief Engineer Answer: OY-54 environmental copper polishing agent developed by our company has been on the market for five years (officially put into the market in 2006), so far nearly 1,000 copper products manufacturers have long been Adopting this process, the process does not need any strong acid and is completely environment-friendly (through SGS certification). The utility model has the advantages of airless tasteless smokeless operation and several times higher brightness than pickling. The utility model has the advantages of low cost and simple operation, and is suitable for mass production of factories.

2, the copper surface degreasing I now use the degreaser on the surface of the copper foil removal effect is not very satisfactory, I would like to ask Europe can always recommend a strong type of degreaser? Consultant: Liu Hongmei Aoyou (Ouyang) Chief Engineer Answer: Do not know the amount of oil and oil type, the center of a OY-29 dedicated copper degreasing agent, you can try for a variety of oil-type and has a strong addition to Oil effect 3, the cleaning of copper (copper pipe cleaning) Now the company bought a group of copper row is dirty, there are stains, what can I do to clean?
Thank you!
Consultant: Mr. Tsang Austrian Yang (Ouyang) Chief Engineer Answer: do not know your copper surface is what the situation, the general situation of cleaning oil, oxide, light and other cleaning, cleaning process can be first degreasing, if there is The scale is then softened with scale and then cleaned brightly for passivation.
Acid pickling (triacid) is generally used on the market to make the copper surface bright. The OY-54 environmental copper polishing agent developed by AOYANG does not need any acid to achieve the bright mirror effect and is recommended.
4, with trichlorethylene cleaning copper can clean it?
Hello, expert, I would like to consult I use trichlorethylene after cleaning copper why not clean, the surface presents a yellow layer, may I have a relationship with trichlorethylene?
Consultant: Ren Jun Aoyou (Ouyang) Chief Engineer Answer: Trichlorethylene can only be used for degreasing and degreasing, for the surface of the oxide and dirt cleaning effect is not very satisfactory, and will continue to oxidize after cleaning.
My company's OY-95 copper oxide skin (copper welding pieces) cleaning agent, designed for serious oxidation of copper parts, and high temperature welding copper oxide skin cleaning design, the copper oxide skin cleaning has a good effect.
5,40-45% copper content How to clean Material: 40-45% copper alloy electronic products.
Requirements: the appearance of light golden yellow conductive, environmentally friendly, low cost, simple process.
Aoyou (Ouyang) Chief Engineer Answer: You can use the center OY-110 copper polishing brightener, copper products for low copper content can also be bright as the new mirror effect.
6, manganese and copper surface light treatment Hello teacher Europe: We are doing manganese copper shunt, and I have done a lot of experiments, but in the end are failed, after treatment of manganese copper is always speckled, no brightness, Easy to change color.
Sincerely need your help.
Austrian Yang (Ouyang) Chief Engineer Answer: Manganese copper and other copper products generally pickling add brightener method, the market before the sale of brightener, and some brass applications have good results, and some have in the copper Very good results, but a lot of brightener in phosphor bronze, phosphor bronze, tin bronze, bronze and other copper alloy is difficult to get good results, I center research OY-110 copper pickling brightener, not only in the brass And pure copper to obtain good results, the more significant effect is in the phosphor bronze, beryllium bronze, tin bronze, manganese and copper on the results, the specific preparation methods see: / / sand cast yellow sand Copper surface is red What is the reason Our company specializing in the production of brass alloy ball valve, with the ultrasonic cleaning machine, throwing the surface of the ball valve became reddish, after grinding ball valve no change, what is the reason?
Consultant: Zhang Xiao Xue Aoyou (Ouyang) Chief Engineer Answer: After cleaning without copper passivation, the surface exposed to the air, it is easy to cause oxidation and cleaning agent or the nature of the slurry to promote the oxidation process, So this is the reason why grinding and ultrasonic cleaning at different times after oxidation, but after any one method of treatment, it is recommended to use copper anti-discoloration, so that is the fundamental, it is recommended that you choose the OY-8 Austrian company's environmentally friendly chromium Passivation agent (SGS certification), 8-10 times stronger than the traditional passivation of chromic acid, a detailed description, please click:
