随着我国石材工业的迅猛发展,使金刚石的需求量逐年上升。据有关资料统计,仅锯片用金刚石就占金刚石总产量的76％,而缺口仍高达8000万克,再加上石材用粗磨、半精磨及砂轮、磨轮等系列工具,使金刚石需求量日渐紧张。笔者日前走访了四川、山东、山西、河北等诸多石材生产厂家,多数未从金刚石工具中回收金刚石,每年白白浪费的金刚石价值达上百万元人民币,因此,我们推荐几种比较可行的回收金刚石的方法。
With the rapid development of the stone industry in China, the demand for diamonds has increased year by year. According to relevant statistics, only diamonds for saw blades account for 76% of total diamond production, and the gap is still as high as 80 million grams. Together with the use of rough grinding tools, semi-finish grinding tools, grinding wheels, grinding wheels and other tools, the demand for diamonds Increasing tension. The author recently visited many stone manufacturers such as Sichuan, Shandong, Shanxi, Hebei, etc. Most of them did not recover diamonds from diamond tools. The value of wasted diamonds reached millions of yuan each year. Therefore, we recommend several more feasible recovery diamonds. Methods.
