Stainless steel door flower industry more and more people of all ages, stainless steel electrolysis more widely, the electrolysis process will encounter many problems, such as electropolishing bright, electrolysis out of stainless steel fittings have stripes on the surface, polishing slow and the electrolysis uneven, these common problems are electropolishing, many people do not understand the principle of electrolytic polishing, the problems encountered in the actual operation, do not know how to solve the last mentioned stainless steel door to spend the electrolysis process, knowing that the stainless steel door to spend electrolysis probably the following, we look at the principle of electrolytic polishing, through the understanding of the principles of electrolytic polishing, we'll know in the electrolytic polishing process the only to the stainless steel door flowers accessories electrolytic better. 
 Electrolytic polishing metal surfaces in the micro-bump in a specific electrolyte and the appropriate current density, anodic dissolution occurs electrolysis workpiece polishing an electrochemical machining technology, also known as electropolishing, abbreviation ECP. First electrolysis workpiece as an anode connected to the DC power supply positive lead, copper and other corrosion-resistant conductive material as the anode of the cathode, connected to the DC power supply. The gap between a certain distance dipped into the electrolyte (usually sulfuric acid, phosphoric acid as the main ingredient), in a certain temperature, voltage and current density, the power of a certain period of time (usually a few minutes), until the small raised part on the workpiece surface dissolved, become smooth and shiny surface can be. 

 Electropolishing main features are: 

 A polished surface does not produce the metamorphic layer, no additional stress and may remove or reduce the original layer of stress 

 2, can be difficult by mechanical polishing of hard materials, soft materials and thin-walled, complex shape, small parts and products using electrolytic polishing process; 

 3, the polishing time is short, and can be polished pieces of the workpiece at the same time, improve production efficiency; 

 Electropolishing can achieve the brightness of the original surface roughness is related generally to improve the two. However, due to the versatility of the electrolyte is poor, life is short and strong corrosive shortcomings, the electropolishing range of applications is restricted. 

 Electropolishing is mainly used for the surface roughness of the metal products and parts, such as the reflection mirror, stainless steel tableware, decorations, needle, spring, leaves and stainless steel pipe and stainless steel door flowers accessories, can also be used for certain mold ( such as bakelite mold and the glass mold, etc.) and metallographic grinding, polishing. 

 Electrolytic polishing of the main process as follows: - wash - and - washed - passivation - Packaging degreasing - washed - rust - washing - electropolishing. 

 By understanding the principles and characteristics of stainless steel electropolishing, we can know the electrolysis should pay attention to what the details, so as to reduce consumption and improve processing efficiency. 


 The principle of electrolytic polishing 
 Electropolishing is placed in the bath in the workpiece anode electrolysis, and leveling the metal surface and produce glossy process. The electropolishing parts formed on the surface passive film dissolution down the metal ion and the diffusion through the membrane. Part performance of the points raised higher than the current density of the sunken points, the dissolution speed, so that the leveling of the surface, shiny appearance. 

 2, electrolytic polishing and mechanical polishing of the advantages of 

 (1) mechanical polishing using metallographic sample polishing machine on the polished surface grinding deformation process of smoothing the surface. So that parts of the surface layer cooling harden the deformation layer, and also mixed with some polishing abrasive electropolishing dissolved by the electrochemical make the polished surface to get the leveling process. Surface is not deformed layer, not mixed with foreign substances, aerobic precipitation due to the electrolysis process, and will be polishing the surface layer of oxide film, but also to improve their corrosion resistance. 

 (2) the shape of complex parts, wire, sheet metal and small parts, mechanical polishing difficult machining, electropolishing has a very good workability. 

 (3) electropolishing, mechanical polishing to improve the surface of the reflective properties of the parts. 

 (4) electropolished leveling role but also to remove the surface inclusions. Then the metal's electronic cold emission reduced. 

 Electropolishing is widely used in the lower parts of the surface roughness and brightness can also be used to improve the life of cutting tools; show parts of the surface cracks, sand holes, inclusions and other defects. 

 In the production process, the stainless steel surface is prone to some of the black oxide or micro inequality affect its value. Only its re-processing, such as mechanical polishing, chemical polishing and electrolytic polishing to improve their own value, and therefore recommend the following process may obtain better results. 

 Current specifications 100A/200A/300A/500A/1000A/1500A/2000A/3000A/5000A/7500A voltage of 12 volts or 15 volts. Can also be customized in accordance with the actual situation of the user. 
 Host a high-frequency rectifier with time, current, voltage, temperature control, swing set and digital display. Contain overheating and short circuit protection device. 
 3, the device pipelined design, very easy operation, greatly improving production efficiency. 
 4, the device configuration pickling tank, electrolyzer, cleaning tank, passivation tank, cleaning tank.

 6, provides a full range of technical services, equipment commissioning, technical training and electrolytic polishing. 

 Applicable range of materials: 
 1, stainless steel (martensite, austenite and ferrite) 
 2, aluminum and its alloys 
 3, copper and its alloys 
 4, iron and steel 

 General portfolio includes: 
 Rectifier + slot polishing + anode rod + cathode rod + cathode stereotype + two copper + quartz heater + slurry + electrolytic Rack (add controller + Temperature Controller). 

 Assembly process: 
 1, the two wires: 1. Rectifier 500A wire 4 points AB in two colors A color wire connected rectifier positive and polishing slot anode rod (middle). B color wire is connected to the anode of the rectifier and polished groove cathode rods (both sides). 
 2, the cathode stereotype: the stereotype should hang in the cathode rods (both sides) Note cards tight and tidy. 
 3, quartz heater: on the both sides of the the Cao body head angle. 
 Quartz heater voltage: 220V single power: 2KW and 3KW. 
 Quartz heater must be in place of the slurry can be heated using temperature 40-70. 
 Just heating a good polishing fluid, the upper and lower temperature inconsistencies, use before mixing consistent. 
 4, the slurry: slurry to enter the polishing tank is heated to 50-65 degrees best new polishing solution is not stable, it is recommended that the electrolytic materials aging, aging time of 5 hours or more, and then put into production.
