FLOOR ABSORBENT GRANULAR PRODUCT

摘要

Granular absorbent products with low amounts of paper fiber are made from recycled paper and include less than about 10 % of paper fibers having a length sufficient to be retained on a 100 mesh screen. The granular absorbents are useful for absorbing liquids spilled on the floor, and are crushable when walked on to provide greater resistance to slipping, and yet have a high resistance to attrition. Process for making granular absorbent material from wastepaper by screening (6) the wastepaper into papermaking fibers and a reject stream, dewatering (40) the reject stream to form a filter cake, breaking up (44) the filter cake to form granular material and sending the granular material which has been dried by dryer (46) to a pin mixer (48).
