Containers: suggested the use of a variety of plastic containers or copper containers, other metal containers disabled. 2, the ratio of proportion: JPL-008 anti-oxidants by 10% -20%, deionized water that is pure 90% -80%, depending on the specific process requirements. 3. Temperature: It can be used in the case at room temperature and warmed passivated, but recommended under heating conditions, so that a higher productivity and better. But should choose a reasonable heating method, if built-in way, it must be a copper heating pipe, or quartz and PTFE (Teflon) heat pipe, if other metal material heating pipe, will change the liquid's performance should not be used. Second, copper anti-discoloration agent process: polished or cleaned workpiece → drying of water (used in complex workpieces) → JPL-008 anti-color-treated copper washed clean → → flow of hot water immersion (about 100 ℃, use to For high corrosion resistance requirements of the product) Third, copper discoloration preventing agent for the workpiece temperature, to let the water on their own volatile or drying) → drying (80-100 degrees for 30 minutes) → JPL-004 closed ( Usage: 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 solution for 5-10 minutes, in principle, less than five minutes, because at room temperature, the passivation film of the liquid in the copper layer is formed within five minutes or so, If the product requires salt spray test more than 8 hours, recommended use under heating conditions; 3. If it is used in the case of heating, it is recommended to control the temperature between 60-70 ℃, most preferably about 65 ℃, under such conditions, JPL-008 as long as two minutes (the recommended treatment time 3 minutes) can be 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. 4. After the above manner, with running water for 1 minute, drying to the surface without drops, taken at a temperature of 70-100 ℃ drying or wiping the surface of the water droplets to dry. Fourth, copper anti-discoloration agent Bath maintenance: 1. Copper anti-discoloration agent life 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. 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. Fifth, copper anti-discoloration agent wastewater treatment: This product can be directly discharged waste. Six copper anti-discoloration agent performance test data (hereinafter data for reference): treatment conditions: copper anti-discoloration solution JPL-008, temperature 65-70 ℃, time of 2min. Comparison conditions: the traditional chromate-treated product. Test Sample: brass and copper pieces each piece a few. Practice has proved that, JPL-008 copper anti-discoloration solution can salt spray test 24 hours does not change color, copper anti-discoloration agent is more effective than conventional chromate passivation effect to enhance the 8-10 times. And nontoxic treatment costs overall downward trend. Seven, product packaging: 25 liters / barrel.
