棉浆粕制备条件对粘胶生产适用性的影响

EFFECT OF PREPARING CONDITION OF LINTER PULP ON PRODUCTION OF VISCOSE

本文论述了过低的棉短绒成熟度会引致粘胶生产过程压榨困难和过滤障碍。描述了在蒸球内设置中通管、来用重蒸轻漂、稳定漂白聚合度、以及漂后的除杂疏解等先进的工艺制造棉浆粕，有助于反应性能的提高，改善粘胶的过滤性能。但打浆时过分切断使纤维长度过短，会影响碱纤维素的压榨。采用干毯抄浆、浆粕存放（一段时间）均有助于浆粕水份均匀性的提高。

in this pager,the adyanced technique of linet pulp making are described.Fof example,lower cotton linter maturity would make press difficult and filering obgtructive So we set mid-flow tube in the interior of the rotarySpherical digester,use deeply cooking-lightly bleaching,Stable the degreeof polymerization of pulp in bleachery,and clean impurity and loosen of thinpulp of bleaching,to increase reactivity of pulp and improve filterabilityof viscose But,when beating,excessive sever brings about shot fiber,thatWill make alkali Cellulose press difficult.To use dryer felt in pulp machine and put the pulp for period will make moisture uniform of pulp sheet.
