摘　　要：以混合竹片为原料,在亚硫酸钠用量与用碱量相等,其他蒸煮参数完全相同的条件下分别进行亚硫酸钠和硫酸盐竹片制浆,并对其蒸煮效果、浆料性质及成纸特性进行比较。实验结果发现:两种方法相比,亚硫酸钠竹浆的得率高、颜色浅、硅含量高;亚硫酸钠竹浆打浆容易,打浆过程打浆度上升快、纤维切断少;在相同打浆度时,亚硫酸钠竹浆的成纸强度高。Using the same chemical dosage,and under the same other conditions,the mixed bamboo chip was cooked by sodium sulfite and sulfate respectively.Then the cooking results,pulp characteristics and sheet performances of the two method were compared.It was shown that the sodium sulfite pulp has higher yield,lighter color and more silicon content than sulfate pulp.The sodium sulfite pulp has better beating characteristics than sulfate pulp,the beating degree rises faster and fiber cutting more differently.And when the pulps were beat with same beating degree,the paper sheet prepared using sodium sulfite is more stronger.
