摘要
硫酸钙晶须是以石膏或工业副产品为原料经特定工艺及配方合成的硫酸钙纤维状单晶体,具有外形完整、尺寸稳定、横截面均匀等特点,是一种具有优良特性的无机材料。由于受生产工艺或设备的影响,硫酸钙晶须的产量较低,质量较差,使硫酸钙晶须在应用上受到一定限制。介绍国内外硫酸钙晶须的制备方法及其各方法的优缺点,阐述硫酸钙晶须晶型的调控和改性的机理,并介绍硫酸钙晶须在改性、环境保护等方面的应用,为相关研究提供一些建设性的建议。
Calcium sulfate whiskers are fibrous single crystals of calcium sulfate synthesized from gypsum or industrial by-products by a specific process and formula.It is a kind of inorganic material with many excellent characteristics,such as complete shape,stable size and uniform cross-section.However,due to the influence of preparation methods and equipment,the yield of calcium sulfate whiskers is not high and the quality is poor,which limits the application of calcium sulfate whiskers to a certain extent.The preparation methods of calcium sulfate whiskers at home and abroad and their advantages and disadvantages were introduced.The methods of calcium sulfate whisker crystal shape control and calcium sulfate whisker modification and its mechanism,the application of calcium sulfate whisker in modification and environmental protection were reviewed.Finally,some constructive ideas for the related research were provided.
