摘要

研究了硫酸钙晶须的基本性能，并与工业碳酸钙(GCC)填料进行了比较。将改性晶须用于造纸填料，并与商用沉淀碳酸钙(PCC)进行了比较。结果表明，当使用未改性的硫酸钙晶须填充纸张时，由于其溶解问题，手工纸的灰分含量较低。添加改性硫酸钙晶须后，纸的灰分明显增加，达到PCC填充的灰分水平。此外，纸张强度大大提高，但光散射系数降低。此外，当改性硫酸钙晶须填充纸灰分含量为21.95%时，改性硫酸钙晶须填充纸的强度性能与灰分含量为14.99%的PCC填充纸基本相同。

SHORT NOTES: A RESEARCH ON THE APPLICATION OF INDUSTRIAL BY-PRODUCT CALCIUM SULFATE WHISKERS IN PAPER FILLING

The basic properties of calcium sulfate whiskers were studied and compared with commercial ground calcium carbonate (GCC) fillers. The modified whiskers were used for paper filling and compared with a commercial precipitated calcium carbonate (PCC). As a result, it shows that when the unmodified calcium sulfate whisker is used to fill the paper, the ash content of the handmade sheet is low because of its dissolution problem. The ash content of the paper increased obviously when the modified calcium sulfate whisker was added, which reached the ash level of PCC filling. In addition, the paper strength increased greatly, but the light scattering coefficient decreased. In addition, the strength property of the modified calcium sulfate whisker filling paper is basically the same as that of the PCC filling paper with 14.99% ash content when the ash content of the modified calcium sulfate whisker filling paper is 21.95%.
