Scraper physical properties

Hardness, wear resistance and chemical resistance determine the main physical properties of the squeegee. In theory, none of these features affect the method of squeegeeing or squeegeeing. In reality, however, all three features affect both the squeegee blade and the sharpening method.

The hardness indicates the hardness and elasticity of the squeegee, which affects the number of blades to be ground to obtain a straight and uniform blade. In general, when grinding the cutting edge instead of cutting off a part of the cutting edge, grinding out a little bit of the cutting edge will make the cutting edge straight. If you cut a part of the edge, the part that must be cut off will become large, and the hardness will decrease.

Abrasion resistance is a feature that prolongs the use time of the squeegee. This benefit, if taken together, becomes like this: The wear-resistant scraper is difficult to grind, so it is also ground again with a grinding device. The sharpening of the highly wear-resistant squeegee is mainly limited to the knife cutting equipment.

The chemical resistance itself does not affect the grinding, but it affects the polished blade. The higher the chemical resistance of the squeegee blade, the sharper the squeegee blade may be without worrying about the previous blade breakage. Each of these physical properties means that you must carefully evaluate the squeegee in order to ensure that it suits your needs. It must be compatible with grinding (the number of times a uniform printed image is ground), grinding equipment (grinding or cutting), and the type of ink required for the printed product.
