EFFECT OF DIFFERENT FILLER ON PRINTABILITY AND PAPER PROPERTIES
Filler and binder are used together with cellulose fibers during paper production. Mineral fillers, which is clay, precipitated calcium carbonate (PCC) and ground calcium carbonate (GCC), are widely used in the papermaking industry during paper product. Generally, producing in paper is used as kaolin and calcium carbonate filler. Recently, Alkyl ketene dimer (AKD) or Alkenyl succinic anhydride (ASA) and Synthetic glue has been used as binder. Unlike known fillers in our work, we tried perlite as a filler. Three different weights were made of kraft cellulose, using perlite that was broken and micro-sized. Resistance tests and offset printing tests were carried out on papers made in laboratory scale.
As a result, it is seen that resistance and printability properties have improved, but, studies are needed to increase the rate of adherence of perlite to cellulose.
