4.2 storage

①Store indoors at 40℃or lower, do not store in high temperature and high humidity, direct sunlight and ultraviolet radiation. (Recommended storage conditions: 23℃±2℃, humidity 60% or lower)

②Do not store near heat-generating equipment or dusty places.

③It is forbidden to bend and press, stack it straight, stack no more than 20PCS.

④The scraping rubber is stored at a low temperature for a long time, and can not be used immediately after being moved to the workshop. It should be placed at 25℃for more than 3 hours before use.

4.3 Grinding

Welcome to use the SPS-SG squeegee grinder for better grinding results

①After using the squeegee, please clean the surface ink and rest on the SPS-DR squeegee rack for 12 hours, waiting for the solvent to be released.

②M type traditional squeegee needs to be grinding in the squeegee holder; FGB/AS with support plate squeegee can be removed for grinding.

③Manual grinding machine for grinding

250 mesh grinding wheel: single grinding   coarse grinding 0.5mm / fine grinding 0.2mm

400 mesh grinding wheel: single grinding   coarse grinding 0.2mm / fine grinding 0.1mm

④The squeegee can be polished with the SPS-Sander  to smooth the edge of the knife edge.

note:

SPS squeegee can be grinded many times, the grinding does not melt, the grinding surface is fine, and the edge is smooth

SPS-SG squeegee grinders are available in a variety of custom-made grinding wheels: U-shaped C-angle R-angle (K1-K5)
