Polyweb urethane screen

Long service life, more than six months;

The open area is as high as ****3% and three times the normal screen, equivalent to that of the imported.

Excellent anti-blinding property. The screen employs inverted triangular sieve wire. Its screen mesh is narrow up and wide down, a design free of the blocking issue in the screen mesh both theoretically and practically.

 Analysis of the PU screens service life and its anti-clogging performance

When choosing a PU screen, one should take into account major factors as its service life, anti-blinding performance and the open area. The service life of PU screen is related to the abrasin resistance and diameter of meshwire. Normally the higher the hardness of the material, the better the abrasion resistance. As for the elastomer PU screen, this may not be the case. Secondly, the service life of the screen panel is proportional to the screen wire section. The wider the screen wire, the longer the life span, but the lower the open area and the lower the processing capacity per unit area; In addition, the anti-blinding performance of the screen is inversely proportional to the hardness of the screen. The lower the material hardness of the screen, the better the anti-blinding performance. Therefore, the best way to examine the performance of the PU screen is to conduct a holistic evaluation of the material, wire diameter (open area) and its hardness.
