白炭黑的制备与应用现状

Preparation methods and application actuality of silica white

重点介绍了白炭黑的制备方法,如气相法、沉淀法、非金属矿法及利用工农业副产物制备白炭黑的方法;对白炭黑在各个行业中的应用做了简要介绍,如橡胶、涂料、牙膏等行业中的应用;展望了白炭黑的发展前景。指出中国气相法白炭黑的生产工艺和规模已经取得了巨大的发展,但仍与国外先进水平存在很大差距,要加大对白炭黑的基础和应用研究,改善生产工艺,提高产品质量,使产品系列化,从而带动相关产业的发展。

The research actuality of superfine silica white both in China and abroad was reviewed. It was indicated that the output of silica white in China increased rapidly in these years, but some top great special nano - sized silica white still needed to be imported. Therefore ,it is quite urgent to start the research on the high quality silica white. The structure and form of silica white as well as its various kinds of preparation methods, such as gas phase method,precipitation method, non - metallic ore method and comprehensive utilization method （ with the by - products from the industry and agriculture as the raw materials ） etc. were introduced in detail in this paper. The application of silica white in the fields of rubber, paint, toothpaste and other industries was introduced comprehensively. In addition ,the development prospect of silica white was predicted and it was also pointed out that the development of correlative industries could be promoted by strengthening the foundation and application study of silica white, ameliorating technologies, improving product quality and producing series products.
