Stainless Steel refers to steel that is resistant to weak corrosive media such as air, steam, water, and chemically etched media such as acids, alkalis, and salts. It is also called stainless acid-resistant steel. In practical applications, steel that is resistant to weak corrosive media is often referred to as stainless steel, while steel that is resistant to chemical media is referred to as acid-resistant steel. Due to the difference in chemical composition between the two, the former is not necessarily resistant to chemical media corrosion, while the latter generally has rust. The corrosion resistance of stainless steel depends on the alloying elements contained in the steel.
Brushed stainless steel is a silky texture of stainless steel surface, which is just a process of stainless steel. The surface is matt, look carefully at the top of the texture, but can not touch it. It is more wear-resistant than the general bright stainless steel, it looks more graded.
The drawing process will lose the thickness of the stainless steel plate to a certain extent, generally 0.1 to 0.2 mm. In addition, because the human body, especially the palm of the hand, has relatively strong oil and sweat secretion, the stainless steel wire drawing plate often leaves a relatively obvious fingerprint by hand, and needs to be scrubbed regularly.
Stainless steel wire drawing surface classification
Brushed board generally refers to surface texture plus collectively, the former name is frosted board, the surface of the pattern has straight lines, chaotic lines (and lines), corrugations and threads.
1, brushed straight lines. Usually, the surface is in a straight line after the mechanical friction of the stainless steel surface is processed. The processing of the wire drawing plate can eliminate the scratches on the surface of the raw material of the stainless steel plate, and also has a good decorative effect. This kind of grain also has a long line and a short line, because this line uses a scouring pad or a stainless steel brush to straighten or short the surface of the plate, and can change the diameter of the steel brush to obtain different thickness lines.
2, brushed lines (and lines). From the far side, the surface sand pattern is composed of a circle of sand patterns. The near part is the non-standard chaotic pattern. It is made by irregular grinding of the grinding head up and down and left and right, and then electroplated and colored. The surface of this grain is matte and the requirements for fabrication are also high.
3, brushed ripples. The manufacturing process is to use the axial movement of the upper set of grinding rollers on the brushing machine or the wiping machine, so that the stainless steel surface is polished to obtain a wave pattern.
4, drawing thread. The manufacturing process is somewhat characteristic. First, a small motor is used. The shaft is provided with a circular felt, and the small motor is fixed on the table top, and is also at an angle of about 60 to the edge of the table. A pallet is then used to secure the stainless steel sheet, and a polyester film is placed along the edge of the pallet to limit the thread speed. In this way, the linear movement of the felt and the mop can be rotated, and the thread width of the same width can be obtained on the surface of the stainless steel plate.
Color stainless steel wire drawing board coloring process
The color stainless steel drawing board is a surface of various colors obtained by chemical water plating or vacuum ion plating coating on the surface of the base plate of the stainless steel drawing board.
At present, the most advanced stainless steel coating coloring process is: vacuum ion plating process.
The process is as follows:
The evaporation source is connected to the anode, and the stainless steel work piece is connected to the cathode. When the high-voltage direct current is three to five kilovolts, a glow discharge is generated between the evaporation source and the work piece. Since the vacuum envelope is filled with an inert argon gas, part of the argon gas is ionized under the action of the discharge electric field, thereby forming a plasma dark region around the cathode work piece. The positively charged argon ions are attracted by the negative high voltage of the cathode, violently bombarding the surface of the work piece, causing the surface particles and dirt of the work piece to be thrown and thrown, so that the surface to be plated of the work piece is sufficiently ion bombarded and cleaned. Subsequently, the evaporation source AC power is turned on, and the evaporated material particles are melted and evaporated, enter the glow discharge region, and are ionized. The positively charged evaporating material ions are rushed toward the work piece along with the argon ions under the attraction of the cathode. When the evaporating material ions ejected on the surface of the work piece exceed the number of spattered ions, they gradually build up to form a layer of strong adhesion. Gold-plated coating on the surface of the work piece. This is the process of coloring the stainless steel wire drawing plate by ion plating.
