CONTAMINANT DISPERSANTS USEFUL IN RECYCLING OF TREATED CONTAINERS

摘要

Methods for controlling wax and other contaminants by improving the dispersion of these materials through the addition of contaminant dispersants to the process of recycling paper and paperboard are disclosed. A preferred contaminant dispersant comprises: a) water; b) a plasticizer; c) an anionic dispersant; d) a surfactant wetting agent; and e) either 1) an acid or lecithin and optionally, a base, or 2) a preneutralized component.
