摘要:选取旧报纸脱墨浆（DIP）、杨木碱性过氧化氢机械浆（APMP）和漂白硫酸盐桉木浆（BKP）3种典型浆料制备“细小纤维”，考察3种浆料的细小纤维在模拟自然水体条件培养一定时期（0~180天）其化学组分含量、形态特征及微观特征的变化。结果表明，随着培养时间的延长，3种“细小纤维”的纤维素、半纤维素和总木素的降解率均逐渐增加；BKP“细小纤维”的变化较DIP和APMP的更为显著。

Abstract:This research collects DIP, APMP and BKP as three typical materials to make“fines”to analyze the variation of chemical components morphological characteristics and micro characteristics of three kinds of fines during 180 days natural cultivation. The conclusion indicated that the degradation rate of cellulose, hemicellulose and lignin of three kinds of fines were increased along with the cultivation time. And the variation of BKP “fines”was more obvious than DIP and APMP.
