添加沉淀碳酸钙(PCC)可有效降低成本,与其他填料相比,PCC能赋予纸张更好的光学性能。但是,增加PCC的用量会降低纤维间结合力,从而降低纸张强度。有文献曾提出增加填料含量而不降低纸张质量的各种途径。细胞腔加填是将大量填料留在纤维细胞腔内。与传统加填相比,这种加填方法纸
The addition of Precipitated Calcium Carbonate (PCC) can effectively reduce costs, giving PCC better paper optical properties than other fillers. However, increasing the amount of PCC reduces the bond between the fibers and thus reduces paper strength. There are various approaches that have been proposed in the literature to increase the filler content without reducing the paper quality. Cell cavity filling is to leave a large amount of filler in the fiber cell cavity. Compared with the traditional filling, this filling method paper
