The impact of zeolite filler on ageing and mechanical failure of paper

Abstract

Abstract The choice of the filler type for paper materials has been a qualitative discussion. The mineral precipitated calcium carbonate (PCC) is used in considerable quantities in the pulp and paper industry as filler. However, alternative filler materials have been researched for improving the properties of paper. In this work, a domestic zeolite (clinoptilolite) filler was used separately and mixed with precipitated calcium carbonate (PCC) fillers. Indeed, the objective of our approach was to explore the structural and mechanical properties of handsheets having filler content affected as a function of accelerated ageing. The results confirmed that the mixed furnish of zeolite and PCC fillers provides positive and synergistic effect on the mechanical properties of ageing handsheets at the low content.
