发明名称 CONTROLLABLE FILLER PREFLOCULATION USING A DUAL POLYMER SYSTEM
摘要 A method of preparing a stable dispersion of flocculated filler particles for use in papermaking processes comprises sequential addition of high and low molecular weight flocculating agents to an aqueous dispersion of filler particles followed by shearing of the resultant filler flocs to the desired particle size resulting in shear resistant filler flocs with a defined and controllable size distribution.
