Kai Union brand environmental electrolytic polishing

Principle Kai Union brand of environmentally electrolytic polishing electrolytic polishing: electrolytic polishing mainly in the positive and negative current through an electrolyte with a total effect of improving the metal surface down to micro-geometry, reducing the roughness of the metal surface to achieve surface light leveling purposes. Electropolishing first major feature is the selective dissolution of the surface from the microscopic point of view is a wavy curved metal surface convex parts was electric rates than the recessed portion was electric rate is high, so the protruding portion It will be dissolved, and the recessed portion of the mucosa due to higher obtained energized low, so was the passive state, is not easy to dissolve. So the initial electrolysis entire surface treatment process. Allow the surface smooth and then slowly into the light of the process, then it bright and smooth the surface. I. Scope A. mainly applied can not be mechanical polishing complex parts (bellows, book sheet, stamping parts, medical equipment, jewelry, doors, etc.) B. suitable quantities, production of large workpieces, more festival costs C. There are special requirements must electrolytic polished workpiece D. anti-corrosion, anti-fingerprint requirement workpiece effect: can effectively improve the corrosion resistance of stainless steel, anti-fingerprint effect, increase the brightness (chrome color) Suitable materials: General Applicable . in all iron and stainless steel bright stainless steel (border side effect) after treatment Second, our unique advantages: 1. Ensure that all iron and stainless steel universal, versatility is our unique advantage. Solve the problem of different materials require different electrolyte on traditional recipes. Reduce costs and improve efficiency. 2, high production efficiency, the light level than the traditional formula increased by more than two times, electrolysis time can be increased by 2 to 8 times. 2. Absolute environmental protection. There SGS certificate, in line with FDA and ROHS not containing chromic acid and glycerin, reliable quality assurance. 3. The liquid stable, there is no medicine scrapped phenomenon, 24 hours of continuous work packages a year. Not even exist a few months syrup to scrap or failure phenomenon. 4, to save costs, conductivity is very strong, just voltage 4 ~ 7V, saving more than half than the traditional recipes (traditional recipes require 8 ~ 15V) 5, provide on-site Built wire technology services to ensure that the requirements to achieve the desired three life: continuous use, there is no retirement phenomenon, only intangible loss when the liquid part added later part of the new medicine to use of methods: 1. workpiece machining status go to skim oil (+ barreling detergent can clean, white oil, water that day, etc., or use our "normal neutral detergent" direct cleaning), mechanical polishing member first addition to wax (can use Division I, "in addition to general-purpose cleaner wax"), flush surfaces are clean 2. It is proposed to ensure simple pickling (use 2% to 10% sulfuric acid solution or 2% HCl + 3% nitric acid solution), viewing the situation will be omitted. 3. Shimizu (unavailable sewage or natural water) wash, rinse the surface pickling. The electrolyte was heated to 60-70 degrees (stainless steel), 70 to 80 degrees (stainless iron), the stereotype or stainless steel plate hanging on the cathode, electrolytic polishing required workpiece with a suitable rack fixed to the anode and holding the workpiece relative to the cathode, and then adjust the voltage of about 3 to 12 volts, 0.5 to 5 minutes out polishing a workpiece, electrolytic polishing process is completed. Electrolytic polishing initial use should use a larger voltage and current in order to bring a solution to the best condition. To the electrolyte appears slightly green, indicating that there are a certain amount of nickel and chromium ions dissolved in the electrolyte, the polishing effect is better. 5 . rinse water rinse. 6. drying the oven about 15 minutes, 100 degrees. test track is surface water. 7. centralized wastewater treatment, plus an alkaline lime or sodium hydroxide and the like, so that PH a value close to 7:00 before releasing no impact on the environment V. effect: 1. electrolytic polishing up to mirror gloss grade, polished surface of the product can reach Ra0.2 ~ 0.5μ, and the surface passivation layer effectively enhance the production of corrosion-resistant capacity. High polishing efficiency, good quality and within a few minutes can be polished to a mirror state. (Best results 8 seconds the light and flat) VI environmental performance 1. The electrolyte does not contain hazardous materials, have SGS test certificate. 2. Wastewater and treatment can be directly discharged, seven had no effect on the environment, maintenance and additional bath? Polished stainless steel parts before entering the tank should be left in the water as much as possible to remove the surface, due to excessive water entrainment artifacts parts may cause serious polishing surface pitting, localized erosion caused by scrapped parts.? long time without electricity circumstances, should the cathode lead plate or stainless steel plate taken out for cleaning, removing acid. ? In the electrolytic polishing process, as the anode of stainless steel parts, iron and chromium which contains continuously conveyed into a metal ions into the polishing liquid at the cathode deposition. As the polishing process, the metal ion concentration increased, when a certain value, these metal ions in the form of organic salts from precipitation within the slurry, sedimentation at the bottom of the polishing groove, end, the slurry must be regularly filtered, The solid precipitate was removed. ? In the polishing groove during operation, with a polishing liquid outer moisture loss due to evaporation and electrolysis continue to consume. Also high viscosity slurries constantly being entrained loss workpiece surface polishing declining, need regular polishing tank to fill with fresh polishing liquid to the slot state.
