METHOD AND APPARATUS FOR LIBERATING THE LATENT PROPERTIES OF A MECHANICAL PULP

摘要

ABSTRACT OF THE DISCLOSUREA method and apparatus for liberating the latentproperties of a mechanical pulp is disclosed. The method maybe used either as a laboratory technique for sample pre-paration for further pulp testing or for treatment of pulpin a mill after refining and before further processing."Latency" is released by recirculating pulp from a poolthereof through a centrifugal pump at a rate of at leasttwice a minute for the period required to release at least70% of the latent properties of the pulps ("Latency").This requires at least one minute and up to 10 minutesdepending on the rate of circulation on of the pulp.
