Spray the anilox roll with sodium bicarbonate, sodium bicarbonate and sodium bicarbonate as the cleaning powder under low pressure to thoroughly clean the dry ink, resin, coating cloth, etc. left in the ink cavity. However, it should be noted that the spraying pressure should not be too high, otherwise the ceramic soil layer may be separated from the anilox roll body, and the general pressure should not exceed 0.1MPa. As sodium bicarbonate and sodium bicarbonate are softening cleaning media, they are soluble, non-toxic and harmless, and meet the global environmental requirements today. Practice has proved that this method has a good cleaning effect, which can not only restore the ink hole volume, but also directly clean on site, including ink bucket, grease, ink, etc. Although this method has only been developed in recent years, it has great potential and is worth popularizing.
Plastic bead jet cleaning of flexographic printing machine
The principle is similar to that of low-pressure spray cleaning, but the cleaning powder is made of plastic beads. This cleaning method can increase the cleaning speed of the anilox roll by 30%, improve the print quality and prolong the service life of the anilox roll. This method has less consumption of plastic beads and no discharge of any harmful substances and precipitation of chemicals during the cleaning process, which is conducive to environmental protection, high efficiency and safety.
