摘　　要：使用硅藻土部分代替粗粒度的重质碳酸钙(GCC)进行涂布实验。研究了硅藻土对无光和亚光涂布纸的光泽度、印刷光泽度、干拉毛强度、油墨吸收性的影响。结果表明,硅藻土在不显著增加涂布纸粗糙度的情况下,能有效降低涂布纸的光泽度。虽然涂布纸的Delta光泽度亦有所下降,但仍维持在较高的水平(>35%)。硅藻土能够增加涂布纸的干拉毛强度,提高K&N油墨吸收性,但会降低印刷密度。硅藻土可以增加油墨吸收速率,但该作用只有在硅藻土使用量较大(15份、20份)时,表现较为明显。Diatomite was used to partially substitute coarse ground calcium carbonate （GCC） to produce coated matte and dull papers. The effects of diatomite on the paper gloss, printing gloss, dry pick, and ink setoff rate were studied. The use of diatomite in paper coating can reduce the paper gloss effectively without increasing roughness too much. Although the Delta gloss declines, it is still good enough regarding to matte and dull papers （ 〉 35% ）. The coated paper containing diatomite has better dry pick resistance and K＆N ink receptivity, but lower ink densi- ty. Diatomite can improve the ink setoff rate, whereas this function only becomes prominent when the amount of di- atomite in the coating formula is sufficiently large （i.e. 15 parts or 20 parts）.
