Studies on the Pulping of the Pinus koraiensis S. et Z. Grown in Korea (I) - Effect of Heat Treatment of Chip on the Kraft Pulping - <Jour. Kor. For. Soc. 61:45-52 1983> Author Chong-Yawl Park
This study was carried out to find the effect of heat treatment on the pitch content and the properties of the kraft pulp produced from Pinus koraiensis. In the results of this experiment, the heat treatment with 40℃ showed the best result in the yields and the pitch contents of kraft pulp of the woods from both artificial and natural stands. Other properties, however, were not improved. They were rather deteriorated with heat treatment. Therefore, it needs to select the heat treatment conditions according to the properties of raw material, the pulping method and the final use of pulp.
Key words: Pinus koraiensis, kraft pulp, pitch content, heat treatment, physical properties of paper
