Maintenance of ink scraper:

For grinding highly wear-resistant ink squeegee, the chemical resistance itself does not affect the grinding, but affects the polished edge. The higher the chemical resistance of the squeegee, the sharper the squeegee may be and there is no need to worry about the damage in the earlier blade. Later, these physical characteristics of the squeegee must be carefully evaluated to ensure that it meets the requirements. It must be compatible with the number of grinding, grinding equipment (grinding or cutting) and printing ink. For example, the physical properties of the squeegee (hardness, wear resistance and resistance) Chemical properties), the compatibility of the squeegee and printing ink, etc., have a great influence on the grinding of the squeegee blade. Whether it is hand-grinding or machine-grinding, due to the heating of the rubber, it is easy to have abrasion accumulation and skirt. The clamp plate should be flush with the bottom edge of the ink knife, so that the rubber will not swell out during grinding. After regular grinding, lightly polish with fine sandpaper to eliminate the skirt. When polishing, from time to time The sandpaper or ink knife wet with water can not only reduce the temperature, but also prevent the abrasive dust from accumulating on the sand surface.
