一、前言为了改善文化用纸的印刷性能以及节约纤维降低成本,在造纸工艺中,通常要在浆料配比中加入一定数量的填料。能够用作造纸填料的无机物质种类很多,天然矿物有:滑石、瓷土、重碳酸钙、石膏、重晶石等。人造的有:沉淀碳酸钙、钙镁白、钛白、锌钡白等。国内造纸业一般最常采用滑石粉,而蜡石粘土则经试验后首次在福州市第二造纸厂使用,效果与滑石粉一样。仅运输差价,每吨约节约45元,第二造纸厂每年需要填料约1800吨,可降低成本8万元。福建省造纸公司于1986年6月初在福州召开“推广应用技术交流会”上向本省造纸行业正式推广“叶蜡石粉造纸填料”。在此
First, the foreword In order to improve the printing performance of cultural paper and save fiber to reduce costs, in the papermaking process, usually in the slurry ratio by adding a certain amount of filler. There are many kinds of inorganic substances that can be used as paper fillers. The natural minerals are: talc, china clay, calcium bicarbonate, gypsum, barite and so on. Man-made: precipitated calcium carbonate, calcium magnesium white, titanium white, lithopone and so on. The domestic paper industry is most commonly used talcum powder, while waxy clay is the first test used in Fuzhou City, the second paper mill, the effect is the same as talcum powder. Only transport the difference, saving about 45 yuan per ton, the second paper mill needs about 1,800 tons of filler each year, can reduce the cost of 80,000 yuan. Fujian Paper Co., Ltd. was held in Fuzhou in early June 1986 to formally promote the “pyrophyllite papermaking filler” to the provincial papermaking industry on the “Promotion and Application Technology Exchange Meeting.” here
