高岭土在造纸工业中的地位 1、概况: 高岭土又称白土或瓷土,目前在造纸工业中主要用作加填或涂布颜料。随着造纸工业的发展,对高岭土的要求有了一个新的飞跃。高岭土质量对造纸起着决定性的作用。世界高岭土的产量,八十年代初已达1500万吨,其中美国580万吨、英国350万吨、苏联220万吨,大部分用于造纸加填和涂布。1982年欧洲和美国造纸工业中高岭土的消耗量如表1所示。
The status of kaolin in the paper industry 1, Overview: Kaolin, also known as clay or clay, is currently used primarily in the paper industry as a filler or coating pigment. With the development of the paper industry, the requirements for kaolin have taken a new leap forward. Kaolin quality plays a decisive role in papermaking. World kaolin production, the early eighties has reached 15 million tons, of which 5.8 million tons in the United States, the United Kingdom 3.5 million tons, 2.2 million tons in the Soviet Union, most of them for paper filling and coating. The consumption of kaolin in the paper industry in Europe and the United States in 1982 is shown in Table 1.
