Environmental copper anti-discoloration agents replace chromated chromated better than traditional programs

- Challenge the same type of product, performance, environmental non-chrome, low cost - SGS Certification: NO.SH579254 / CHEM This product has been certified by SGS which record is to replace numerous South Korea, Taiwan, Japan similar products OY-8 anti-copper color (antioxidant) agent OY-8 anti-discoloration agent performance physical and chemical stability, non-toxic, tasteless, non-volatile, non-hygroscopic, does not decompose sublimation not absorb dust and harmful gases H2S, SO2, etc., can effectively resist heat, salt spray , germs and other metal erosion, better wetting and high corrosion resistance. OY-8 has excellent electrical properties, but also dehydration, anti-color, anti-corrosion triple role, no corrosive effect on metal, copper, silver and imitation gold plating resist significant protective effect, especially for preventing copper and imitation gold discoloration of the surface, the effect is significant. The product can also be added in conjunction with other additives, such as water-based, solvent-based sealer, varnish oil, anti-rust agent products, and 10% per liter of working solution can play a good role, especially for rust-proof copper, gold, silver, zinc, steel and other metal plays an invaluable role. A built-bath method: 1. Container suggested the use of a variety of plastic containers, can not use metal containers, except copper container. Then OY-8 antioxidants and deionized water (pure water) 1: 9 ratio with good; 2. The working fluid and the case can be warmed at room temperature passivation, but recommended under heating conditions, so that a higher productivity and better. But the warming should choose a reasonable way heating method, if built-in way, it must be a copper heating pipe, or quartz and PTFE (Teflon) heat pipe, if other metal materials plus temperature control, will change the liquid's performance, should not be used. Second, the process: polished or cleaned workpiece → drying of water (used in complex workpieces) → OY-8 copper anti-discoloration (antioxidant) agent) treatment → → hot soak and clean running water (about 100 ℃, with to be used for heating the workpiece, the purpose is to let the water on their own volatile or drying) → drying → OY-7 closed (for high corrosion resistance requirements of the product) Third, use: 1. A. After the workpiece degreasing chemical polishing and cleaning B. bright acid copper plating or other copper came out; first rinsed twice with running water, washed once with deionized water (this could make as much as possible into the liquid in the more less impurities, thereby extending the service life of the drug solution); 2. If you are operating at normal temperature, which must be tackled in the working fluid 5-10min, in principle, less than 5min, because at room temperature, the passivation film may be present in the copper layer was formed about five minutes, if the product Requirements salt spray test more than 8 hours, recommended use under heating conditions; 3. If you are using in the case of heating, the recommended temperature controlled between 60-70 ℃, preferably about 65 ℃, in this condition, OY-8 as long as two minutes (recommended treatment time of 3 minutes) will be able to a complete and uniform and shiny passivation layer, to achieve the best anti-color effect, therefore, in principle, I do not recommend the use of room temperature operation center. 4. After the above manner, with running water for 1 minute, drying to the surface without drops, taken at a temperature of 70-80 ℃ drying or wiping the surface of the water droplets to dry. Fourth, Bath maintenance: 1. The working fluid lifetime depends largely on the extent of previous work clean. Pickled parts to be washed clean, can not have residual acid into the passivation solution. (Acidity increased, the film dissolves copper member, are not effective). Thus, the passivation and pickling solution was to separate, to avoid hexavalent and trivalent chromium ions to enter, and before entering the anti-discoloration bath complex products, to avoid the presence of residual liquid, so long, in order to make the solution life at their best. 2. Equipment selection: selection of equipment is crucial, the container generally plastic-based, copper heating pipe must be, or the selection of an external heating method (which can provide design and temperature control device by the company). 3. Do not let other metal parts into the solution. 4. Analyzing the life of the general solution to the PH value standards, new bath with PH value is generally 6 ± 1, near neutral, when the solution PH exceed 6-7 ± 3, the solution should be discarded, if not anti-discoloration requires time high , can test as the standard, under normal circumstances, this is a good solution in the case of PH2-9 passivation, if the high quality requirements, they can be controlled within the range of PH 5-7 and 4-8 . 5. In addition, anti-discoloration clean sink bath needs regular checks before its PH value PH test paper, if you find water from neutral, the proposed replacement of water immediately, otherwise discoloration preventing agent will be affected. Five wastewater treatment: This product can be directly discharged waste.
