1、SPS-FGB Fiber Glass Board Squeegee instructions

The traditional squeegee is all urethane rubber, which is printed for a long time，After the squeegee absorbs the solvent in the ink, the hardness is reduced, the expansion deformation, the printing angle α is unstable, and it is not suitable for precision screen printing. The Fiber Glass Board Squeegee is combined with the glass fiber board and the scraping glue, which has the elasticity of the scraping rubber and the support line of the glass fiber board. The long-time printing can maintain a stable printing angle and the printing ink thickness is uniform.

4.Production process

The entire process from receiving an order to shipping

5.2 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.

5.3 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)
