Use of dadmac containing polymers for coated broke treatment

摘要: DADMAC containing polymers, both homopolymers and copolymers are used in effective coagulating amounts to treat cellulosic fibres recycled from coated broke recovery. The polymers either or preferably acrylamide. Recycle of can cause difficulties when the paper manufacturing process because coatings contain binders which what is referred as "white pitch", accumulation holes paper, build-up residues sticky masses, clogging felts like manufacture paper. use eliminates this difficulty making cellulose ottained recycle.
