liquid state fermentation,cell culture,
  1. Features:
            Stainless steel workpieces as the anode, is immersed in a special electrolyte energized, the workpiece surface is electrolyzed to obtain a smooth glossy surface, this method is called electrolytic polishing (Electro Polishing - EP) or electrochemical polishing (Electrochemical Polishing) orelectrolytic polishing (Electrolyte Polishing)
  2. With mechanical polishing comparison:
    Project Mechanical polishing Electrolytic polishing
    Shape and size Can handle large objects, such as tanks, but can not handle complex shapes, small parts and thin Can handle complex shapes, small parts and thin, but limited the electrolytic cell, deal with size restrictions generally less 1kL fermentor before electrolysis.
    Processing characteristics Cutting and grinding smooth shiny surface of the metal, stainless steel metal crystals cause deterioration and plastically deformed Not required polishing does not plastically deformed
    Processing characteristics Local heating of organizational change and abrasive material and grease left on the metal surface, must be dealt with separately, in order to obtain clean surface The finished clean surface
    Corrosion resistance Poor The corrosion resistance of the polished surface
    Luster Lighter, but more difficult to lasting Gloss long duration
    Environment Dust No
  3. With chemical polishing comparison:
    Project Chemical polishing Electrolytic polishing
    Chemicals Chemicals Using electricity instead. Electrolytic polishing longer bath life, long-term use
    Environment Polluting gases No
    Metal surface General More luster
    Corrosion resistance Poor The polished surface of the good corrosion resistance
    Luster Poor Gloss long duration
  4. Range of applications and features:
            Electrolytic polished stainless steel in the manufacturing sector of the semiconductor industry and other instruments, kitchen, crafts valves, fittings, pipe fittings, seamless pipe, fluid control components such as stainless steel laser cutting workpiece, can be used to goIn addition to stainless steel laser cutting burr, clear the stainless steel surface oxide to obtain a smooth, clean surface to increase the workpiece corrosion resistance, reflectivity, and does not affect the size of the workpiece precision.
