一种二次预处理浸液B及其在制备麻竹本色纸浆的应用
摘要：
本发明公开了一种二次预处理浸液B及其在制备麻竹本色纸浆的应用，属于本色纸制备技术领域，所述二次预处理浸液B，以重量份为单位，包括以下原料：过碳酰胺10‑20份、氢氧化钾4‑6份、氨基羧酸0.3‑0.5份、五氧化二钒0.1‑0.2份、水35‑150份。所述二次预处理浸液B应用于制备麻竹本色纸浆中，所得纸浆得率和白度显著高于现有技术制得的纸浆得率和白度，此外，纸浆滤水性好、强度大、成本低，制浆过程能耗低，所制备的纸浆能够适用于纸浆模塑制造、生活用纸制造的本色纸浆。
摘要（英）：

The invention discloses secondary pretreatment immersion liquid B and application of the secondary pretreatment immersion liquid B in preparation of dendrocalamus latiflorus munro unbleached pulp, and belongs to the technical field of unbleached pulp preparation. The secondary pretreatment immersion liquid B comprises, by weight, 10-20 parts of percarbamide, 4-6 parts of potassium hydroxide, 0.3-0.5 part of aminocarboxylic acid, 0.1-0.2 part of vanadium pentoxide and 35-150 parts of water. The secondary pretreatment immersion liquid B is applied to preparation of the dendrocalamus latiflorus munro unbleached pulp, and the yield and whiteness of the obtained pulp are obviously higher than those of pulp obtained in the prior art. In addition, the pulp is good in drainability, high in strength and low in cost; and the pulping process is low in energy consumption, and the prepared pulp can be suitable for the unbleached pulp of molded pulp manufacturing and household paper manufacturing.
