摘要
针对大锅法片碱颜色发红现象， 从电槽流出碱质量、硝酸钠和硫磺的投入量、熔融碱澄清时间及温度控制等方面剖析其原因。提出了保证片碱外观颜色达标的对策。
The cause of red platy alkali was analysed based on the alkali quality in cell, feeding of sodium nitrate and sulfur, settled time, temperature control, etc. Some suggestions removing the red colour of the platy alkali were made.
