    • 본 발명은 재활용되는 제지 공정수의 칼슘 경도 조절방법에 관한 것으로서, 더욱 상세하게는 제지공정에서 단기순환되는 백수(White Water)에 탄산나트륨 또는 탄산수소나트륨을 첨가하여 공정수내의 칼슘이온을 탄산칼슘으로 침전시켜 제거하므로써 칼슘 경도를 조절하며, 또한 탄산칼슘 침전물을 제거함에 있어서는 부상부유처리법을 수행하고 이러한 침전물 제거공정후에도 미처 제거되지 않은 탄산칼슘은 지필에 보류시켜 초지계로부터 배출시킴으로써 공정수 재활용에 따른 칼슘 스케일 및 지방산 칼슘염의 발생을 미연에 방지하며 탄산칼슘 제거과정에서는 미세분도 함께 제거하여 탈수성을 개선하고 제지용 고분자 첨가제의 효율을 향상시키는 효과가 있을 뿐만 아니라 아울러 공정수를 폐쇄화시킴에 따라 폐수 배출로 비롯되는 환경오염을 줄� �고, 공정수 및 계 내에 투입된 에너지를 절약하면서 제지용 첨가제와 주원료인 섬유의 유출을 방지하게 되는 재활용되는 제지 공정수의 칼슘 경도 조절방법에 관한 것이다.

    • PURPOSE: A method for controlling calcium hardness in paper manufacturing process is provided, which is characterized in that sodium carbonate or calcium hydro carbonate is added to white water to settle calcium ion. CONSTITUTION: Silo white water which is shortly circulated is purified by settling calcium ions, and the calcium carbonate ions are absorbed. Carbonate ion and sulfate ion react with calcium ion and produce precipitate. Sodium ion which replaces calcium ion does not react with other ions and does not produce scales in the water. The precipitates can be removed by using a sedimentation chest, but because the sedimentation chest requires an extra device for neutralizing, a floating method is appropriate. Carbon dioxide which replaces air can remove calcium carbonate and control the concentration of hydrogen ions.
    • 目的:提供一种在制纸过程中控制钙硬度的方法,其特征在于将碳酸钠或碳酸氢钙加入到白水中以沉淀钙离子。 构成:通过沉淀钙离子来净化短循环的筒白水,碳酸钙离子被吸收。 碳酸根离子和硫酸根离子与钙离子反应并产生沉淀。 取代钙离子的钠离子不与其他离子反应,并且在水中不产生垢。 通过使用沉淀箱可以除去沉淀物,但由于沉淀箱需要额外的中和装置,所以浮法是合适的。 替代空气的二氧化碳可以除去碳酸钙并控制氢离子的浓度。
