In daily life and production, it is inevitable to polish stainless steel. According to the specific needs, the commonly used methods are: electrolytic polishing, electrochemical polishing, mechanical polishing, etc.
The electrochemical polishing process is divided into two steps: (1) Macroscopic leveling: The dissolved products diffuse into the electrolyte, and the geometric roughness of the material surface decreases, Ralμm. (2) Low light leveling: Anodized, the surface brightness is improved.
Electrolytic polishing: use acidic electrolyte (strong acid), put the sample to be thrown into the back current (about 7mA), and the anode will dissolve. Due to the size of the current, those protruding parts will dissolve faster, and the surface tends to be flat to achieve the final result. The effect of polishing (the effect can be seen within about 10 minutes). The basic principle of electrolytic polishing: the same as chemical polishing, that is, by selectively dissolving the tiny protrusions on the surface of the material to make the surface smooth. Compared with chemical polishing, the influence of cathode reaction can be eliminated, and the effect is better.
Mechanical polishing: To achieve the decorative effect of the rough surface of the stainless steel plate, it must be polished with an abrasive belt polishing machine on the carrier roller frame. First, use a 120# abrasive belt. When the surface color is reached, change the 240# abrasive belt and throw it to the surface. When the color arrives, change the 800# abrasive belt, and when the surface color arrives, change the 1200# abrasive belt, and then throw it to the effect of the decorative stainless steel plate.
All kinds of small and medium-sized stainless steel precision parts deburring, chamfering, descaling, rust removal, bright polishing, mirror polishing, etc.
Methods as below:
Uses: Remove the oxide skin produced in the cold rolling and stamping process of stainless steel (screws, pendants, hardware, decorations, etc.), bright and beautiful.
Features: chemical polishing, fast and convenient, cost-effective, good brightness, more than similar products in the market.
Usage: In the drum, add water at the ratio of 1:20 and stir well, add the workpiece to be polished, grind for 5-15 minutes, and clean the oil stains; add the polishing liquid in the ratio of 1:20-50 to make up Working fluid, vibrating polishing or rolling polishing, the time is about 15 minutes, rinse with clean water, centrifugally spin dry or air dry and dry.
Uses: Remove oil stains and oxide skins produced in the process of stainless steel, screws, pendants, hardware, stamping parts, cold rolling and stamping, bright and beautiful.
Features: chemical polishing, degreasing polishing is completed at one time, fast and convenient, economical and efficient, and the brightness is very good.
Usage: The two-in-one polishing liquid is mixed with water in the ratio of 1:20-50 to make a working liquid, vibrating polishing machine or rolling polishing, the time is about 15 minutes, rinsed with clean water, centrifugal drying or air-drying, and air-drying.
Note: It is suitable for workpieces with light oil. The polishing liquid is a concentrated liquid. The proportion of water added during polishing depends on the actual material conditions. Do not get into eyes or mouth, if touched by mistake, rinse immediately with water.
Uses: used for post-processing and polishing of stainless steel fasteners, fishing gear accessories, chains, pendants, springs, hardware and other stainless steel products, compared with stainless steel drum polishing: stronger acidity, more suitable for polishing with oxide skin layer or surface roughness higher workpiece.
Features: This product is made up of cleaning agents, brighteners, corrosion inhibitors, surfactants, etc., which significantly improves the surface brightness of stainless steel parts, making the parts bright and beautiful. The combination of mechanical and chemical polishing is economical and efficient. Brightness is good.
Method of polishing stainless steel
Usage: 1. The main function of this product is polishing, and it has quick-acting scale removal performance. It can be used with stainless steel drum polishing solution. The first step is to use this product to roll out surface burrs, oxide skin, trachoma, etc., and the second step is to use stainless steel Cylinder polishing liquid is used for polishing, and the gloss is better, and it can also be used alone. http:www.paoguangji8.com
2. Liquid preparation: Pour the grinding and polishing liquid into the drum equipped with stainless steel parts according to 2-3% of the weight of the parts (or increase the amount according to the oxide layer), and then add twice the water (that is, polishing liquid: water = 1 : 1-2 diluted before use).
3. Treatment process: roller rolling polishing, the time is subject to the brightness of the workpiece, about 1-2 hours, the polishing liquid is removed, rinsed with water, centrifugally dried, air-dried or air-dried.
4. According to the surface roughness of the workpiece, for workpieces with large roughness such as stainless steel chains, etc., it can be used with abrasives (such as polishing abrasives, etc.) to appropriately extend the rolling time.
Note: 1. This product is acidic, do not get into the eyes and mouth; it is corrosive to the skin, if it comes into contact with it, rinse it off with water. 2. Store in a cool place, long-term effective.
Packaging: 25kg plastic drum, 200kg Tietong
Uses: used for polishing stainless steel fasteners, fishing gear accessories, chains, pendants, springs, hardware and other stainless steel products after processing
Features: It is made up of cleaning agents, brighteners, corrosion inhibitors, surfactants, etc., with mirror gloss, rich foam and long-lasting effect.
Usage: 1. The main function of this product is polishing. The workpiece polishing is divided into two steps: the first step is to remove oil, and the second step is to use this product for polishing
2. Liquid preparation: Pour the polishing liquid into the drum with stainless steel parts according to 1-2% of the weight of the parts, and then add the same weight of water as the polishing liquid (that is, polishing liquid: water = 1:1 diluted before use) .
3. Treatment process: roller rolling polishing, the time is subject to the brightness of the workpiece, about 0.5-1 hour, remove the polishing liquid, rinse with water, centrifugally dry, air dry or air dry.
4. According to the surface roughness of the workpiece, it can be used with abrasives.
