硫酸钙晶须制备机理及技术研究进展

近些年,随着我国环境问题的恶化,我国开始发展绿色环保的工业。在一些非金属的环保材料中,性价比高的新型材料硫酸钙晶须被广泛应用。随着需求量的增大,硫酸钙晶须的制备开始受到重视并逐渐的发展,水压热法和常压酸化法是当前制备硫酸钙晶须的传统方法。由于我国在工业生产中,一些工业生产的副产品就是石膏或者一些含钙的废液,这就为我国制备硫酸钙晶须提供了丰富的原料,这些原料成本低廉,对于工业的副产物又进行了二次利用,对环境的保护起到了很大的影响,在以后的发展和应用中,是一种发展很好的新型环保材料。

Research Progress on Mechanism and Preparation Technique of Calcium Sulfate Whiskers

In recent years, with the deterioratibn of the environment problem in our country, our country began to develop green industry, In some non metal material ＇of environmental protection, new material, calcium sulfate whisker cost - effective is widely used. As demand increased, preparation of calcium sulfate whisker beginning to receive attention and gradually development, hydrothermal method and atmospheric acidification ：method are the traditional method for the preparation of calcium sulfate whisker. Because our country in industrial production, some by - products of industrial production is gypsum or some calcium containing wastewater, provides a wealth of raw materials such as the preparation of calcium sulfate whisker, the low cost of raw materials, the by - products＇of industrial and for the two time to use, to the great influence oh the protection of the environment up, development and application in the future, is a new type of environmentally friendly materials is a very good development.
