(Summary description)    The types of stainless steel are different, and the etching process is also different, but the general process is as follows: stainless steel erosion → degreasing → water washing → etching → water washing → dryness → screen printing → thousand dryness → water immersion 2 ~ 3min → etching pattern Text → Washing → Deinking → Washing → Pickling → Washing → Electrolytic Polishing → Washing → Dyeing or Electroplating → Washing → Hot Water Washing → Dryness → Soft Cloth Throw (Gloss) Light → Spray Clear Paint → Dryness → Inspection → Waste Packaging.     1. Disposal before etching     The processes before the stainless steel etching are pre-treatment. It is a key process to ensure that the screen printing ink has good adhesion to the stainless steel surface. Therefore, it is necessary to completely remove the oil stains and oxide films on the metal etching surface. Degreasing should be based on the oil pollution status of the work piece to make a plan, it is best to carry out electrical degreasing on the silk screen to ensure the effect of degreasing. In addition to the oxide film, the best etching solution should be selected according to the type of stainless steel and the thickness of the film to ensure that the appearance is clean. It should be dry before screen printing. If there is moisture, it will also affect the adhesion of the ink, and it will affect the effect of subsequent pattern etching and even aliasing, which will affect the decorative effect.     2. Screen printing     Screen printing should be based on the needs of printing manufacturing standard pattern screen printing screen. In the pattern decoration process, the silk screen is mainly used for maintenance, and the number of times when applying the photoresist is more, in order to make a thick screen template, so as to make the covering performance good, and the clarity of the etched pattern is high. Under the action of light, the screen film's adhesive film produces a photochemical reaction, so that the light is partially cross-linked into a water-insoluble adhesive film, but the unexposed light is partially dissolved by water to reveal the screen space, so that the silk film The screen is etched with a leaky pattern that matches the black and white positive sun pattern.       Fix the screen printing screen with pattern on the screen printing machine, use alkali-soluble acid-resistant ink to print the required pattern on the metal plate, and then stop etching after it is dry.     3. Disposal after etching     After etching, the screen printing ink must be removed. Ordinary acid-resistant ink is easily soluble in alkali. Immerse the etched board in a sodium hydroxide solution of 40-60g / L at a temperature of 50-80 ° C and immerse it for a few minutes to remove the ink. After the removal, if you request high brightness, you can stop polishing and then stop dyeing. In order to avoid discoloration and increase wear resistance and corrosion resistance after dyeing, you can spray transparent varnish. Some metals themselves have good corrosion resistance and are not stained, or they can be painted without transparent paint, depending on practical needs.

Three steps of stainless steel etching

(Summary description)    The types of stainless steel are different, and the etching process is also different, but the general process is as follows: stainless steel erosion → degreasing → water washing → etching → water washing → dryness → screen printing → thousand dryness → water immersion 2 ~ 3min → etching pattern Text → Washing → Deinking → Washing → Pickling → Washing → Electrolytic Polishing → Washing → Dyeing or Electroplating → Washing → Hot Water Washing → Dryness → Soft Cloth Throw (Gloss) Light → Spray Clear Paint → Dryness → Inspection → Waste Packaging.

    1. Disposal before etching

    The processes before the stainless steel etching are pre-treatment. It is a key process to ensure that the screen printing ink has good adhesion to the stainless steel surface. Therefore, it is necessary to completely remove the oil stains and oxide films on the metal etching surface. Degreasing should be based on the oil pollution status of the work piece to make a plan, it is best to carry out electrical degreasing on the silk screen to ensure the effect of degreasing. In addition to the oxide film, the best etching solution should be selected according to the type of stainless steel and the thickness of the film to ensure that the appearance is clean. It should be dry before screen printing. If there is moisture, it will also affect the adhesion of the ink, and it will affect the effect of subsequent pattern etching and even aliasing, which will affect the decorative effect.

    2. Screen printing

    Screen printing should be based on the needs of printing manufacturing standard pattern screen printing screen. In the pattern decoration process, the silk screen is mainly used for maintenance, and the number of times when applying the photoresist is more, in order to make a thick screen template, so as to make the covering performance good, and the clarity of the etched pattern is high. Under the action of light, the screen film's adhesive film produces a photochemical reaction, so that the light is partially cross-linked into a water-insoluble adhesive film, but the unexposed light is partially dissolved by water to reveal the screen space, so that the silk film The screen is etched with a leaky pattern that matches the black and white positive sun pattern.
 
    Fix the screen printing screen with pattern on the screen printing machine, use alkali-soluble acid-resistant ink to print the required pattern on the metal plate, and then stop etching after it is dry.

    3. Disposal after etching

    After etching, the screen printing ink must be removed. Ordinary acid-resistant ink is easily soluble in alkali. Immerse the etched board in a sodium hydroxide solution of 40-60g / L at a temperature of 50-80 ° C and immerse it for a few minutes to remove the ink. After the removal, if you request high brightness, you can stop polishing and then stop dyeing. In order to avoid discoloration and increase wear resistance and corrosion resistance after dyeing, you can spray transparent varnish. Some metals themselves have good corrosion resistance and are not stained, or they can be painted without transparent paint, depending on practical needs.
