Preparation for Calcium Sulfate Whisker and Its Application Process

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 be used to improve asphalt softening temperature,etc.It's a new material that has broad development prospect.
