常州兄弟不锈钢电解抛光有限公司1（Changzhou brothers stainless steel electrolytic polishing Co., Ltd. 1） 常州兄弟不锈钢电解抛光有限公司1(Changzhou brothers stainless steel electrolytic polishing Co., Ltd. 1) Daily maintenance of electrolytic polishing line stainless steel electrolytic polishing Daily maintenance of electrolytic polishing liquid 1. electro polishing, surface polishing will discover why like spots or small? Cause analysis: before polishing oil removal, the surface is still a stain. Solution: the "bond brand oil wax removal liquid, 1:10 water, 60 - 90 DEG C under the condition of immersion for 5 to 20 minutes. As a long time after use should consider replacing the new liquid. 2. after polishing why local surface patches are black? Cause analysis: can not thoroughly clean the oxide skin. There are still local scale. Solution: increase the removal of skin strength, can choose the "bond brand stainless steel descaling liquid", "stainless steel descaling paste and other products. For derusting descaling more products, products can be applied Zhengbang Technology Co. Ltd. consulting. 3. after polishing workpiece edges and tip corrosion caused by what are the reasons? Cause analysis: parts of the edges, the tip of the current is too large, or the electrolyte temperature is too high, the polishing time is too long, resulting in excessive dissolution. Solution: adjust the current density or temperature, or shorten the time. Check the electrode position in the corners of shielding etc.. 4. why the workpiece polishing after light and dark gray? Analysis of reasons: the possible electrochemical polishing solution has no effect, or the effect is not obvious. Solution: check whether the electrolytic polishing liquid used for a long time, the decline in the quality, or the solution composition proportion. 5. polishing surface with white stripes is going on? Cause analysis: solution relative density is too high, the liquid is too thick, the relative density is greater than 1.82. Solution: the degree of agitation of the solution increases, if the solution density is too large, dilute with water to 1.72. At 90~100 deg.c and heated for one hour. 6. why is the polished surface of yin and Yang, and the phenomenon of local dull? Cause analysis: the placement of the workpiece and the cathode is on or not, the workpiece mutual shielding. Solution: adjust the workpiece, the workpiece and cathode in place, so that the power distribution is reasonable. 7. after polishing workpiece surface smooth, but some point or piece of not enough light, or not bright vertical stripes, generally what is the reason? Cause analysis: may be produced on the surface of the workpiece polishing post bubble detachment and have failed to attach on the surface or surface flow line. Solution: increase the current density, the gas evolution in order to increase the bubble desorption, or increasing the stirring speed of solution, the increase of solution flow. 8. parts and hanger contact point dull and brown spots, the surface of the rest light is what reason? Cause analysis: may be rack parts and poor contact, causing the current uneven distribution, or hanging parts and contact points are less. Solution: Polish hanging point of contact, the good electric conduction, or increase the area of the point of contact parts and rack. 9. the same slot polishing parts and some light, some bright or not bright, local. Cause analysis: the same groove polishing work too much, resulting in uneven distribution of current, or overlap between the workpiece, shielding. Solution: reduce the number of the same groove polishing workpiece, workpiece position or attention. Ten Why near the Polish parts and parts with recessed part hanger contact point contact with silver white spots? Cause analysis: may be recessed parts by the component itself or hanging screen. Solution: change the location of parts, the recessed part can get the power line or narrow the distance between the electrodes or increasing the current density. 11. has been in strict accordance with the standard operation process, why there are more or less polished parts surface corrosion phenomenon? Cause analysis: whether the solution temperature is too high or the current density is too high, if the solution is no problem, and strict operation, it is to deal with the problem before polishing. Solution: strict implementation of electrochemical polishing treatment before operation, avoid corrosion in pickling process. Don't put the water in the cleaning part surface into the polishing trough. 12. "brand stainless steel bond common electrolyte" why use a period of time there will be a bubble? Cause analysis: the surface of the workpiece without removal of oil, some oil floating on the surface of the electrolyte, difficult to operate. Solution: this situation has emerged, suggestions will remove surface oil, oil does not appear in the proposal before polishing. What is the relationship between sulfuric acid and phosphoric acid 13. electrochemical polishing liquid? Cause analysis: sulfuric acid more, polishing speed is too fast, the metal matrix can accelerate corrosion, phosphate adsorption more, a mucous membrane on the surface of the workpiece and polishing brightness down, slow down. Of course, does not rule out other factors. Solution: adjust the appropriate proportion of phosphate sulfate. Can also choose to "bond various non chromium electrolytic additive formula. 14. polishing after the surface gloss, there are white spots on a pale yellow ground, cause what reason? Cause analysis: may be the electrolytic polishing solution if the content is too high, even more than 1.5%. Solution: chromium ions belong to heavy metal ions, have carcinogenic effects on the human body, the pollution of the environment, can be used without chrome polishing liquid. Recommend the use of the "brand stainless steel bond common electrolyte". 15. electrolyte cost accounting is mainly what? Is the main electricity, electrolyte, rectifier, electrolyzer, heating pipe, plate, bar. 16. stainless steel of various materials in electrolytic polishing when the current density is how much? What is the cost associated with the electrolysis? Cause analysis: in the market situation of various materials in conventional stainless steel electrolyte density: 200 series stainless steel current density at 25 to 50 amperes, 300 series stainless steel current density at 15 to 30 amperes, 400 series stainless steel current density at 30 - 55 amperes. Solution: choose the bond brand stainless steel 200 series stainless steel general electrolyte "current density at 15 to 25 amperes, 300 series stainless steel in 10 to 15 AMP, 400 series stainless steel between 25 - 30. The larger the current density, the greater the power consumption. In the electrolytic cost accounting, electricity accounted for a large proportion. 17. polishing after clean throw without luster, with light blue shadow what reason? Cause analysis: may be the electrochemical polishing solution, without heating and electricity, low operation temperature or solution. Solution: 120 DEG C heating electric polishing liquid for an hour or the electrolyte is heated to a predetermined temperature. Eighteen After polishing, no light and yellow spots caused by what are the reasons? Cause analysis: the relative density of the possible electrochemical solution is small, is less than 1.70. Solution: adjust the relative density of electrolytic polishing or heating in the 80 - 100 C concentration to increase the relative density. Or is the replacement of the new 19. after polishing, why out of the groove on the emergence of brown spots? Cause analysis: may be polished enough, or for a short time. Solution: first, appropriate to extend the polishing time, if there is no effect, it may be the problem of insufficient temperature or current density. Why is the 20. electrolytic prone to spark phenomenon? Cause analysis: the cause of this phenomenon has three factors: one is the hanger and workpiece contact point two is not strong, the electrolyte density is too low, the high current density is three. Solution: change several hanger and workpiece connection method, as much as possible to increase the contact point and workpiece rack. If the electrolyte density is too low, can replace the electrolyte, suggested the use of "brand stainless steel bond common electrolyte". 21. stainless steel electrolyte operating temperature what are the effects of electrolytic polishing? How much is the best temperature? Cause analysis: General electrolyte temperature of 50 - 90 DEG, low temperature, polishing speed is slow, brightness down. The temperature is too high, the liquid corrosion on the workpiece speed, easy to cause the workpiece after corrosion, easy decomposition of electrolyte constituents. Solution: the low temperature should be heated to a predetermined temperature, heating can be used for various heating tubes (such as quartz heating tube, titanium material), long time working temperature will rise, when the temperature exceeds 90 degrees should stop working, the heat can be used to stir or cooling cycle. The best temperature is 50 - 90 DEG C, the best temperature Zhengbang brand stainless steel general electrolyte "for the 50 and 80 C. 22. stainless steel workpiece surface is uneven, pitting is convex, what causes? Cause analysis: surface corrosion is more, electrolyte micro corrosion leveling, more corrosion of electrolyte can not completely remove, such as the extension of the polishing time, a large number of iron ions into the electrolyte at the bottom, reduce the service life of the electrolyte. Solution: the workpiece surface corrosion clean. Recommend the use of the "brand stainless steel bond activation solution", "rust water", "cleaning derusting descaling liquid and other products. What are the 23. main factors affecting the electrochemical polishing? Temperature, time, material of workpiece, electrolyte, voltage, current, workpiece position. In 24. stainless steel electrolytic polishing, surface adsorption layer of light red material, again into the electrolyte will have short reaction time, what is the reason? Cause analysis: using copper hanger, electrolyte adsorption to the anode surface of copper ions into the influence of polishing quality, there will be a short reaction time again into the electrolyte because the copper ions dissolved on the surface of the workpiece. Solution: use the titanium clamp in the fixture, with bare PVC resin baking film, at the point of contact to scrape the insulating film, with conductive metal leakage. 25. Yin and Yang pole best area ratio is the number? The anode cathode is 1:2 than - 3.5. What is the 26. best polar distance? The anode cathode distance best distance is 10 - 30 cm. How the 27. bond brand stainless steel electrolytic polishing in general maintenance after aging? Aging Zhengbang brand stainless steel general electrolyte can add sulfuric acid (density of 1.84), was added to the bath weight of 6%, or 6 386A? 1H/L.? 28. the first electrolytic polishing, do not throw the brightness, and the surface of the workpiece into black or gray, what is the reason? Cause analysis: the occurrence of this phenomenon is generally two reverse, reverse after it dissolved into the workpiece into a positive, Cathodic Adsorption, adsorption of dissolved iron nickel chromium ion in the workpiece in the solution on the workpiece surface, forming a layer of film adhesion is not good. Solution: the negative electrode is reconnected, the anode is connected with the anode, the cathode is connected with the negative pole.
