Abstract

Wood pitch deposition onto the surface of
papermaking machinery continues to be a
costly problem. Fixatives - substances
said to attach wood resin to wood fibre -
have been used to alleviate wood pitch
deposition to varying degrees of success.
This paper aims to evaluate to what
degree fixatives alter the colloidal wood
pitch particle size.
We were able to show how different wood
resin fixatives alter the colloidal wood pitch
particle size at three different pH values
(4.75, 6.85 and 8.06). The fixatives can be
divided into two categories, colloid disrupting
and colloid stabilising, according to how
they change pitch particle size.
