一、云母加拿大是世界上磨细和碎片金云母的主要生产国。与世界其他国家相比,加拿大是第五位最大的云母生产国。自从70年代后期生产高径厚比金云母和表面处理云母以来,最近几年云母在塑料中作为增充剂的需求量激增。据报道,1986年加拿大云母的消耗量增长了7.4％,达3334吨。其中用于石膏复合材料制品、涂料和油漆的消耗量占总消耗量的83％。 1. Mica Canada is the world’s major producer of milled and fragmented phlogopite. Compared with other countries in the world, Canada is the fifth largest mica producer. Since the production of high-path-thickness phlogopite and surface-treated mica in the late 1970s, the demand for mica as an extender in plastics has increased dramatically in recent years. According to reports, the consumption of mica in Canada increased by 7.4% to 3,334 tons in 1986. Among them, the consumption of gypsum composite products, paints and paints accounted for 83% of the total consumption.
