Cartaspers SCH and Cartabond DST.01 are deposit-control products that can help papermakers to improve machine cleanliness and operability when using wastepaper as a raw material. Cartaspers SCH makes use of nanotechnology to introduce trillions of tiny polymer particles into the wet end of a paper machine. The hydrophobic emulsion particles are derived from a hard, high-melting-point polymer. During operation, the tiny polymer spheres associate themselves with other hydrophobic components in the pulp slurry. Through passivation, this agent renders sticky contaminants nonsticky, which prevents agglomeration and fouling. Cartabond DST.01 is a low-charge cationic polymer solution designed to reduce turbidity in the wet-end circuits.
