摘要:测试了巴西高岭土CENTURY、美国高岭土KAOFINE、岳阳华泰涂布重钙C95等3种颜料的粒度、亮度、pH值、水分、325筛余物等基本性能指标,研究了不同颜料对轻量涂布纸性能的影响,考察了不同颜料在轻量涂布纸上的应用效果。结果表明,含22.5%巴西高岭土CENTURY、7.5%美国高岭土KAOFINE和70%华泰重钙C95的混合涂料涂布纸具有较好的印刷光泽度、油墨吸收性和表面强度,是一种综合性能较优的轻量涂布纸涂料。 |
Abstract:The basic performance indicators of three pigments (Brazilian kaolin CENTURY, American kaolin KAOFINE and Yueyang Huatai ground calcium carbonate C95) including particle size, brightness, pH value, moisture, and 325 sieve residues were tested. The influence of different pigments on the quality and performance of the lightweight coated paper were studied. The application effects of different pigments in lightweight coated paper were investigated. The results showed that light coated paper with mixture coating including 22.5% Brazilian kaolin CENTURY, 7.5% American kaolin KAOFINE and 70% Huatai ground calcium carbonate C95 had better performance of gloss, ink adsorption and surface strength. Thus, the mixture coating had excellent comprehensive performance towards light coated paper. |
