Stripping method of solvent resistant photosensitive adhesive

silk below 300 mesh, stripping method of solvent resistant photosensitive adhesive

after printing, various ink stains on the silk plate can be directly cleaned with opening agent, preferably with industrial grade cyclohexanone and other solvents, on the scraper surface and printing surface, especially the scraper surface, until it is clean

after the ink on the plate is removed, the film cannot be removed directly, because there are still solvents and other components on the silk plate, which must be removed again. 5 ~ 10% sodium hydroxide solution can be used, and then industrial detergent or silk special detergent can be used to clean in the water tank, until there is no solvent component on the silk plate is clean, then the plate can be removed

release is a particularly important process. Take a little film stripping solution and pour it on both sides of the silk plate, apply it evenly, the adhesive layer will slowly change color and take off until it is removed, and then spray it with a high-pressure water gun

sometimes there are unclean words and images on the silk plate, which cannot be removed with the film removal solution, which is caused by the fine ink and stains left in the silk hole. At this time, solvent can be directly used to erase, such as cyclohexanone, pore opening agent, etc., and the words and images on the silk plate will slowly be dissolved by the solvent, but the silk plate can't be as clear as new. At this time, immediately wipe the decontamination powder or toothpaste on the scraping surface and the printing surface, and then add a little cyclohexanone and solvent while wiping, until the words and images on the silk plate disappear. The reason for this is that cyclohexanone can dissolve and eliminate stains and impurities, remove tiny inks and stains in the holes, and the decontamination powder particles are relatively fine. The silk holes below 300 mesh can pass smoothly, which can bring out all residues in the holes together. Then wash it with a high-pressure water gun, and finally neutralize it with glacial acetic acid, wash it, and dry it

300 mesh silk, solvent resistant photoresist film removal

300 mesh silk, solvent resistant photoresist film removal and regeneration:

Imported 300 mesh silk with high mesh number is much more difficult than low mesh silk, and the higher the mesh number is, the more difficult the stripping is. The high mesh wire hole is very small, the wire diameter is very fine, and the decontamination paste is relatively coarse. The high mesh wire hole cannot pass through, and it is easy to block and damage the wire. Therefore, DX grinding paste is generally used for the stripping of the high mesh version. The grinding paste particles are very fine, and the cleaning and decontamination function is good. Using grinding paste to make the plate cleaner and cleaner should be installed on the foundation of concrete. The price of grinding paste is slightly expensive. Usually, decontamination powder is used for wires with less than 300 mesh, but grinding paste must be used for high mesh wires. The film removal regeneration of high mesh version is the same as that of coarse mesh version. It is particularly important for routine testing: one link of elongation at break and shrinkage recovery is to remove the ink on the plate after printing. It is best to take off the plate immediately. The longer the storage time is, the more difficult it is to take off the plate. Use grinding paste for final cleaning
