橡胶补强填料——纳米碳酸钙的生产及改性技术进展

纳米碳酸钙是一种高附加值的无机精细化工产品，平均粒径在0．1nm～100nm范围内，属纳米级粉体材料。与普通碳酸钙产品相比，具有粒子细、比表面积大、表面活化率高、白度较高等特点。另外，同其他类似功能型产品相比，它具有原料易得、价廉、白度高、着色力强、

Production and modification technical progress of nano calcium carbonate

Nano calcium carbonate industry is a high-tech and high value-added sunrise industry. This article describes the production methods and surface modification technology of nano calcium carbonate. Through modification, it expands application area to a certain extent. This issue points out comparing with other countries, there are still large gaps for China＇s current modification technology, mainly including less modifier varieties, limited research and development capacity. These factors affect the development and production of Chinese specific, functional-level nano calcium carbonate product. From now on, the industry inners should take more efforts on their research works and expanding the variety to promote the rapid and healthy development of nano-calcium carbonate industry.
