摘要
介绍了2017年我国磷石膏产量及利用情况,详细介绍了磷石膏利用存在的问题及措施。2017年我国磷石膏产量为75 Mt,同比下降1.3%。磷石膏利用途径呈现多元化的态势,仍依赖初级化利用方式,综合利用程度与当前形势发展要求差距较大。通过开发推广Ⅱ型无水石膏、加快磷石膏制备硫铝酸盐水泥技术研发、大力发展抹灰石膏特别是机喷抹灰石膏等大量化利用技术,努力开创磷石膏利用的新局面。
The production and utilization of phosphogypsum in China in 2017 were indtroduced.The existing problems and meas- ures were presented in detail.In 2017, China witnessed a phosphogypsum production of 75 Mr, 1.3 percent down as compared to the pre- vious year.Albeit a trend of diversification had been growing in the utilization approach of phosphogypsum, the elementary utilization method was still largely relied on.Extend of comprehensive utilization didn＇t match the developing situation.New perspectives in the utili- zation of phosphogypsum could be created by the measures of developing anhydrite type Ⅱ , speeding up the research and development of sulphur aluminate cement preparation technology from phosphogypsum, and developing massive utilization technology of plastering gyp-sum, especially machine spray plastering gypsum.
