Application of Chemical Modification of Biomass in Resin Technology;

In this paper,the properties of pitch and deposit in pulp were introduced,as well as its harm and the way of wet-end control,in order to provide theory support to the effective pitch control in the mills.

In order to evaluate the capability of lignin degradation and pitch elimination from Masson pine chips by nature white-rot fungi,20 white-rot fungus strains were obtained by petri dishes screening and petri dishes color-reaction screening.

The degradation rates of lignin and pitch were determined after 3 days,5 days,7 days and 9 days respectively.
