摘要
硫酸钙晶须是一种性能优良、价格低廉的新型非金属环保材料。其制备方法主要有两种——水压热法和常压酸化法。目前制备硫酸钙晶须的原料主要是生石膏,由于我国工业副产石膏比较丰富,可以使用工业副产石膏作为原料制备硫酸钙晶须,另外,还可以使用工业含钙废液为原料制备硫酸钙晶须,这不仅可以降低成本,还可以提高资源的利用率、保护环境。硫酸钙晶须的应用很广泛,可以用于摩擦材料、增强组元、环境工程、造纸,还可以用于提高沥青软化温度等,是一种具有广阔发展前景的新材料。
Calcium sulfate whisker is a new non-metallic environmental material that has excellent properties and low price. It has two main methods of preparing： hydrothermal method and atmospheric acidification method. The main preparation material is gypsum. Our country is rich in industrial by-product gypsum, so the industrial by-products and industrial waste liquids can also be used to make calcium sulfate whisker, which can not only reduce costs but also improve resource utilization and protect environment. Calcium sulfate whisker can be used in many fields, such as friction materials, enhancing component, environmental engineering, papermaking, and also he used to improve asphalt softening temperature, etc. It＇s a new material that has broad development prospect.
