中国科学院长春综合研究所有机研究室硫酸盐纸浆组,利用东北林业资源,如黄花松、红松、白桦、青杨等,用快速蒸煮法及混合蒸煮法制造洋灰袋纸,获得了很好的成绩。并在硫酸盐纸浆漂白试验、废液回收问题及中间工厂建立上都取得了较丰富的经验。该组为响应政府节约木材的号召,又进行了利用针叶树、阔叶树的腐朽材及针叶树红板皮代替原木制造洋夹袋纸之研究。经过一年的努力,中间试验已获成功。在现厂试验 Chinese Academy of Sciences, Changchun Institute of Organic Research Sulfate pulp group, the use of Northeast forestry resources, such as yellow cedar, Korean pine, white birch, green poplar, etc., with quick cooking and cooking method to produce gray sack paper, get a very good Score. And in the sulfate pulp bleaching test, waste recycling and the establishment of the middle of the factory have made a wealth of experience. In response to the government’s call for conservation of wood, the group conducted a study on the use of coniferous and deciduous trees of deciduous trees and conifer red planks instead of logs for the manufacture of foreign paper bags. After a year of hard work, the pilot has been successful. In the factory test
