变性淀粉在麦草浆上的留着

The retention of modified starch on wheat straw pulp

研究了不同种源、不同取代度的各种变性淀粉在不同湿部化学特性下在麦草浆上的留着情况,且用桉木浆做了对照实验。总的说来,淀粉在麦草原浆上的留着率较桉木原浆上高,在桉木原浆上的添加量以不超过2%为宜,在麦草原浆上的添加量以低于3%为宜。

Several factors affect modified starch retention on bleached chemical wheat straw pulp including degree of substitution and wet endchemical characteristics are studied in this paper. The eucalyptus bleached chemical pulp is studied for contrast. The results show that theretention rate of modified starch on wheat straw pulp is higher than that on eucalyptus bleached chemical pulp; the level of addition in wheatstraw pulp should not be higher than 2% and that in eucalyptus bleached chemical pulp should not be lower than 3%.
