Rapid method for liberating the latent properties of mechanical pulps

摘要

A method and apparatus for liberating the latent properties of a mechanical pulp is disclosed. The method is a laboratory technique for sample preparation for further pulp testing. "Latency" is released by recirculating pulp from a pool thereof through a centrifugal pump at a rate of at least four times per minute for the period required to release all the latent properties of the pulp sample ("Latency"). This depending on the rate of circulation may be completed in as little as one minute.
