| 摘 要： | 为了保留竹子的天然抗菌性,以四川慈竹为原料,利用碱顶浸低温硫酸盐法和常规硫酸盐法制备竹浆,对两种工艺条件下的浆料性质进行对比,探讨了碱预浸低温硫酸盐法蒸煮的最佳工艺条件.结果表明,最佳碱预浸条件为:预浸温度120℃,NaOH用量12％,渗透剂用量1.75％,预浸时间 30 min；预浸后的蒸煮条件:用碱量(以Na2O计)20％,硫化度18％.碱预浸低温硫酸盐法浆粕中α-纤维素含量能够达到91％以上,且较常规硫酸盐法有更好的抗菌性.

| Abstract: | Properties of two kinds of bamboo pulps using Neosinocalamus affinis as new material and obtained by alkali-preimpregnation and non-preimpregnation kraft pulping were compared in order to improve the cellulose property of dissolving bamboo pulp and its antibacterial property.The optimum cooking conditions of alkali-preimpregnation kraft pulping were also determined as preimpregnation with 10% NaOH and 1.75% DHQ for 30 min;alkali charge in the following cooking was 20% alkali dosage and sulfidity 18%.Compare... |
