碱预处理
1.
Effect of alkali pretreatment on selective oxidation of cotton fibers;
碱预处理对棉纤维选择性氧化的影响
2.
The results show that unbleached acetosolv pulps have low brightness compared with other pulps, oxygen delignification of acetosolv pulps needs higher NaOH charge, and alkali pretreatment of acetosolv pulps could reduce the consumption of NaOH in oxygen delignification and avoid the serious drop in pulp viscosity.
对三倍体毛白杨乙酸浆进行了TCF漂白的初步研究,发现与其他浆种比较,乙酸原浆具有较低的白度;乙酸浆进行氧脱木素时需要高的碱用量才能得到低的卡伯值,进行碱预处理可以降低氧脱木素段的碱用量,避免纸浆粘度较大程度的降低;并研究了漂白前后纸浆物理强度的变化。

补充资料：碱洗
分子式：
CAS号：
性质： 一种化学清洗方法。用氢氧化钠和碳酸钠或磷酸三钠配制成的高强度碱液，以软化、松动、乳化及分散沉积物。往往添加一些表面活性剂以增加清洗效果。常用于锅炉的除油污垢，碱沉积物他日硅酸盐垢)。碱洗在一定温度下使碱液循环进行。时间一般为6～12h，根据情况也可以延长。
