The common stainless steel plate drawing has three kinds of effects: straight wire grain, snowflake grain and nylon grain. Straight wire is from top to bottom uninterrupted pattern, generally use fixed wire drawing machine workpiece for back and forth movement can be processed into; snowflake pattern is a popular degree of higher one, by the rules of the point composition, can be processed using the buggy sandpaper to get the effect of nylon pattern is composed of long and short lines, because of the nylon wheel texture is soft because of the ability to grind the uneven parts in order to achieve the effect of the nylon pattern.
Stainless steel plate drawing is very concerned about the process and procedures, usually with the drawing machine to repair and restore the product scratch position and weld, in order to ultimately achieve the overall artistic effect of drawing. Stainless steel cylinder surface can usually only be processed by lathe or grinder, only requires surface treatment, you can use a special grinding tool clamped on the lathe through the sandpaper and cloth for polishing; if the precision and surface roughness have very high requirements, you need to grind through the grinder for polishing. Surface drawing processing, usually only on the raw material plate processing. The surface of raw material stainless steel plate is processed with NO.4 (snowflake) or HL (wire drawing) before the finished product is processed. The finished product can retain the surface effect of the original plate through the common processing methods.
Oil straight refers to the oil mill straight wire, that is, in the oil mill after drawing, ink after stainless steel plate surface oil brightness, and then do a layer of drawing, that is, a kind of frosting treatment. Now there is a whole volume of ink drawing, and ordinary drawing compared to the oil mill straight wire drawing texture clarity is high, the whole document eye gloss is good, the overall effect of the finished product is very good, a large number of elevator decoration and other surface requirements of the higher equipment above.
Stainless steel plate surface processing and color processing methods. Production of colored stainless steel plate methods include high temperature oxidation method, chemical oxidation method, electrochemical oxidation method, ion implantation method and gas phase cracking method. The following into these processing methods one is the high temperature oxidation method is in a specific molten salt stainless steel plate pieces immersed in and maintain a certain process temperature, time, so that the stainless steel plate pieces to generate a certain thickness of the oxide film, and show a variety of different colors. The second is the chemical oxidation method, is in a specific solution, by controlling the temperature and time to generate all kinds of film color, usually use the method is more, but to keep the color of the product is consistent, must use the reference electrode to control. The third is the electrochemical method, is in a specific electrolyte, by controlling the temperature, voltage and time to generate a certain thickness of chlorinated film color, this process is more mature, the use of a wider. And the ion implantation method is through the vacuum in the gasification of ions deposited on the stainless steel plate surface, the method is suitable for mass production.
