硅酸钙加填轻型纸的应用研究

摘要

The effect of porous calcium silicate loading, which is made from high-alumina lfy ash, as ifller for light basis weight paper, on finish and paper performance was investigated. The loading effect was compared with calcium carbonate paper. The results show that the bulk of light basis weight paper increases signiifcantly when loaded by porous calcium silicate, increasing from 2.67cm3/g to 3.21cm3/g, when the dosage of porous calcium silicate increases from 0 to 33%. Compared with calcium carbonate ifller, porous calcium silicate as ifller can increase ifller retention significantly, while reduce the concentration of white water.%研究考察了从高铝粉煤灰中提取的多孔硅酸钙用于轻型纸加填对浆料及纸张性能的影响，并与碳酸钙加填纸进行对比。结果表明：采用多孔硅酸钙加填后，轻型纸松厚度显著提高，当添加量从0提高至33%时，纸张松厚度从2.67c m3/g提高至3.21c m3/g，与碳酸钙填料相比，采用硅酸钙加填后，填料留着率大幅提升，有效降低了白水浓度。
