磷石膏制备硫酸钙晶须及晶须造纸应用的研究进展
Preparation of calcium sulfate whisker from phosphogypsum and its application
摘要
Abstract
The performance characteristics and growth mechanism of CSW were reviewed in this paper. The preparation methods of CSW, hydrothermal synthesis and atmospheric acidification method were also introduced, especially the influence of preparation process on the growth of CSW by hydrothermal synthesis was detailed. The pretreatment method of phosphogypusm and its effect on the morphology of CSW were summarized. Also, the additives for the preparation and modification of CSW were investigated, as well as the functional mechanism. The application of CSW in paper making was introduced. The key issues in paper making, including the solubility of CSW, the compatibility between CSW and paper fibers and the improvement of CSW whiteness and strength, were analyzed emphatically. The main development trend in the future should be the research on pretreatment technology of phosphogypsum, the additives of CSW, and the influence of preparation process on the performance of CSW, and the quantitative relationships between the performances of CSW and papers.关键词
