As a cleaning item, washing powder is not only used in daily life, but also in lithographic printing work. First, it can play the role of cleaning plate. In lithographic printing, the dirty version of the PS plate is a common problem. Dirty plates are sometimes used. Neither the cleaning solution nor the wetting powder can be completely removed. If you encounter this phenomenon, you may wish to use a little washing powder, dissolve a certain amount of washing powder with the cleaning solution or water, and gently wipe the dirty parts of the printing plate with a sponge. Special attention should be paid to the process of wiping. If the dirty part of the printing plate is a flat screen, the force should be smaller, otherwise the printing plate may be wiped. Second, it can be used to clean the enamel layer on the surface of the rubber roller. After use, the impurities in the paper and ink will condense on the surface under high-speed rolling to form a smooth glazed layer, which changes the physical characteristics of the elasticity of the rubber roller, thereby affecting the quality of ink absorption and ink transfer. It is not easy to clean the surface of the rubber roller, especially the stubborn glazed layer formed for a long time, but the use of washing powder has special effects on the above problems, and the method is simple. Adjust the cleaning solution and washing powder In the form of a paste, apply it to the rubber roller to be cleaned, and then wipe it back and forth vigorously until the surface of the rubber roller is cleaned without reflective effect. It should also be noted that it is best not to machine the rubber roller after cleaning. Place it vertically for a while to restore its elasticity before use. Only then can the best results be achieved. Pp Forks,Plastic Pp Forks,Polypropylene Fork,Disposable Pp Forks Anhui Jianfeng Environmental Protection Technology Co., Ltd , https://www.jfplacutlery.com
