OY-54 environment-friendly eco-friendly copper brightener chemical polishing of copper chemical polishing process is our research center after a long trial and research, developed environmentally friendly high-bright copper and copper alloy (brass H58 above applies; copper, copper-nickel alloy, etc.) chemical polishing process. From the initial temperature processing upgrade to the current room temperature processing (especially in summer), technically has increased by a big stage. Process out of the product can be obtained several times higher than traditional pickling polishing effect, easy to control and master, and certainly the environment, without any strong acid. Completely away from a mist, smoke, odor work environment. Fully meet the requirements of clean production enterprises chemical polishing. First, the process: 1. OFC: workpiece racking (basket) → OY-29 at room temperature acidic degreasing agent → three countercurrent rinsing → OY-54 chemical polishing → → addition to film three countercurrent rinsing (2-5% dilute solution *, poor yellow Copper then ultrasonic vibration ash) → three countercurrent rinsing → OY-8 passivation → three countercurrent rinsing pure water → drying → → → product packaging 2 test. Aerobic copper: workpiece racking (basket) → OY-95 Black soften → three countercurrent rinsing → OY-29 at room temperature acidic degreasing agent → three countercurrent rinsing → OY-54 chemical polishing → → except three countercurrent rinsing membrane (2-5% * dilute solution, then the ultrasonic vibration inferior brass ash) → three countercurrent rinsing → OY-8 passivation → three countercurrent rinsing pure water → drying → → → product packaging two tests, environmentally friendly copper chemical polishing solution and process conditions :( slots when equipped with a volume ratio) range of hydrogen peroxide process conditions (35-50% content) 30% OY-54 polishing brightener 5% pure water 65% PH value 0.7-1.5 temperature 45-55 ℃ soaking time method brass 1-3min, copper 2-4min containers require more than 304 stainless steel, plastic heating pipe material stainless steel, Teflon, quartz tube, titanium tubes do not need to stir it can not happen filters 1. Equipment requirements :( I can offer a dedicated copper environmental cleaning machine, specific advice 0577-28882977) plastic containers, preferably PVC or PP material produced a rectangular slot, depending on the size of production. If the production capacity, the overflow trough is designed to form (e.g. electrophoresis tank), to facilitate the flow of the bath, the temperature uniformity (in the production process, the bath temperature will exotherm). 2. A bath methods: first wash tank, and then was added to the aquarium clean tap water (preferably deionized water); and then slowly added to the desired hydrogen peroxide and OY-54 polishing brightener; supplementary volume of water since the last prescribed, Stir detect PH, spare. 3. Usage: A. Small items (small size and light weight): You can make a mesh basket, the product is poured into a basket for cleaning, washing Austrian foreign Wenzhou Technology Co., Ltd. Copper Series Product Manual Service Hotline: 400-9922-399 turn 1 QQ : 800-083-488 basket when appropriate jitter, in order to avoid overlap with each other between the product, resulting in uneven polishing phenomenon. B. There are holes or grooves of products like: Making a jig or four baskets, the product stays good jig, or put the product there was a regular place in the basket, the groove down to avoid when removing residual drugs fluid. Immersion cleaning tank were then referred to, the degree of light as a standard time, polishing to a suitable shaking, to ensure uniformity of cleaning. C. A large area of ??copper: Make appropriate treatment tank, will be erected in the trough of the product is stationary, must be completely immersed in the bath. In addition to the film to be removed when the entire product surface passivation film of brown or black, if the brightness is not enough, you can repeat the polishing 1-2 times (once for each film are subject to stripping and washing). D. Copper or copper: Designing an auto assembly line, you can control, according to a fixed time slot after chemical polishing chemical addition to the film → → water washing → passivation process. Third, pay attention: 1. Production control PH value of a good bath, when normal production PH = 1.0-2.0, the optimum value of 1.0, when slotted PH value is not 1.0, you can use * Regulation (new slotted general solution no adjustment); when PH≥1.5 when using AR * or OY-54 polishes (with no brightness adjustment *) adjusted according to experience is one percent of the total bath every two hours supplementary mass ratio; when PH value within the normal range is slow, appropriate complementary hydrogen peroxide. 2. Time polishing process as long as possible, over-etching phenomenon does not occur, because the surface of the product it will automatically protect the passivation film is formed, this layer of film from yellow to reddish brown or even black, more uniform oxide film the more light, the better the transparency, the better the quality of its polish; if a film is not good, the surface is inconsistent, it is not the product surface becomes irregular bright pink or bright colors. 3. If the product is a light bright enough, you can repeat Stripping chemical polishing → → washing program 1-2 times. 4. The temperature of the polishing solution to the vital to 45 ℃ most suitable. When the temperature exceeds 60 ℃, easy polishing liquid natural decomposition and emit heat generation solution scrapped. In the production process, the solution will be automatically raised, and therefore, attention to temperature control. The reason is usually below 55 ℃ belong to the normal range, the effect of temperature is another bath of copper ions within the accumulation of excessive time will result in a solution of continuous warming, according to experience, a good hydrogen peroxide (50%) From slotted to boiling time is usually 12-24 hours this, the gap between the main cleaning with controlled density, temperature, if cooling conditions are closely related. 5. For the oxide scale formed at a temperature of the workpiece, the process was quite slow at room temperature, the temperature may be raised to 40-55 ℃, treatment can 2-3min; if the above treatment has not yet reached the degree of brightness, place the workpiece * In an aqueous solution containing about 40% of, 40-50 ℃ in soaking 10-20min, or use our dedicated OY-95 high-temperature copper oxide remover, and then put the polishing solution can handle. For heavy oil of the workpiece, the first to carry out pre-treatment, you can use the company OY-29 is processed at room temperature acidic degreasers, and then to deal with this process. 6. This product should be stored in a cool place, not close to the fire and placed under the sunlight. 7. This process is crucial to the choice of hydrogen peroxide, before polishing liquid bulk configuration, the best to test a small amount of hydrogen peroxide, in order to avoid unnecessary losses, some manufacturers of hydrogen peroxide in this process can not be made good protective film, so , so they could not bright copper surface. 8. The concentration of hydrogen peroxide solution choice is the key to life's work, with 50% hydrogen peroxide content of the production of more than 27% of the content will nearly double, so we recommend using 50% hydrogen peroxide content, with 50% hydrogen peroxide in the slot when the added amount need only 150-250 ml / l can be, in the production process, such as to exhaust may be added as appropriate. 9. Copper car parts, casting time back in dilute solution, not too long film, the film is removed subsided, or likely to cause discoloration and loss of light. And there is a certain part of the cast for hanging gray, with supporting the use of ultrasound, so that you can achieve good results, especially below 58 copper pieces, if there is no ultrasound factories, Stripping please hang ash with inferior copper OY-96 Cleaner stripping. 10. Brass member in the cleaning process is prone to redness, can be treated after OY-54 out directly into the Stripping groove, does not require washing, to avoid redness. 11. You can add a new bath with bath into a little old, so new bath is easier to enter the normal operating state, if it is the first time there is no old bath, you can add pieces of scrap copper (preferably copper pieces) treatment for 5-15 minutes, the temperature rose to about 45 degrees, so that the syrup quickly into the normal state, then remove that access to normal production. Fourth, labor protection: This process is completely environmentally friendly, no need for special labor protection, wear plastic gloves or masks to operation. Five wastewater treatment: polishing solution PH value of between 1 and 2, this solution does not discharge standard copper ion content is too high, so when generating waste, waste first boiled, then placed in a treatment pool, sodium hydroxide and the amount of PAM (coagulant), Austrian foreign Wenzhou Technology Co., Ltd. Copper Series Product Manual Service Hotline: 400-9922-399 turn 1 QQ: 800-083-488 make waste of copper ions flocculation with the formation of copper hydroxide, and then detect the PH value, close to local emission standards, the solution is discharged, copper hydroxide precipitate barrels recycling. Six, product packaging: plastic bucket 20 kg / barrel.
