表面活性剂及胺(铵)盐在纸浆漂白中助漂作用的研究

Role of surfactant and amine(ammonium)salt in pulp bleaching process

论述了胺 (铵 )盐及表面活性剂在碱法麦草浆次氯酸钠漂白中的助漂、减氯及提高白度的作用 ,讨论了不同助剂用量对纸浆白度和残余有效氯的影响。研究结果表明 :使用这些助剂可以明显地提高纸浆白度 ,显著地减少漂液中的有效氯的使用量和漂白废液中残余氯的含量 ,起到了促进漂白和减少环境污染的作用。

Surfactant NP-7 and amine salt can cut back chlorine and raise white degree in pulp bleaching process.The affection of dosage to the pulp white degree and chlorine remainder was discussed.The results showed that these aids can raise the white degree significantly,and decrease the chlorine content in the waste liquid.
