资源简介:
Broke pulp in a paper making process is obtained by pulping broke, and the broke pulp is made of fibrillated cellulose fibers and cellulose ester (CE) staple fibers having a denier per filament (DPF) of less than 3, or a cut length of less than 6 mm, or crimped, or non-round with a DPF of less than 3. The broke pulp can be added to the stock preparation zone of a wet laid manufacturing facility and fed through a refiner.
造纸过程中产生的损纸浆(broke pulp)由损纸经制浆工艺制备而成,其纤维组分包含原纤化纤维素纤维,以及满足以下任一条件的纤维素酯(cellulose ester,CE)短纤维:单丝线密度(denier per filament,DPF)小于3旦尼尔、切断长度小于6毫米、具有卷曲结构,或截面呈非圆形且单丝线密度小于3旦尼尔。该损纸浆可添加至湿法成型造纸装置的备料工段,并经精浆机处理。
