WERKWIJZE VOOR HET AFVOEREN DOOR EEN AFVOERKLEP VAN EEN POLYMEERBRIJ.

摘要

A slurry containing polymer particles having an average particle diameter of 0.1 to 1 mm suspended therein is discharged smoothly from a discharge valve without valve clogging by operating the valve such that the degree of valve opening is set within a range II for a valve operating time t1 and within a range III for a valve operating time t2; the time t1 being from 5 to 60 seconds, the time t2 being from 1 to 10 seconds, the range II being a range of valve openings at which the valve is gradually clogged with the polymer particles discharged, and the range III being a range of valve openings at which the valve permits continuous discharge without clogging.
