摘要:

日本白石工业株式会社是全世界最早生产纳米碳酸钙的企业,产品种类多、质量优良,生产能力达到25万t/a,是世界领先的纳米碳酸钙供应商。为了解国外纳米碳酸钙的先进生产工艺,为中国纳米碳酸钙行业的发展提供借鉴,详细介绍了日本白石工业株式会社纳米碳酸钙生产工艺。对原料精选、煅烧、消化、精制、碳化、陈化、表面处理、压滤、干燥、粉碎、包装等工序或环节进行了描述,并与中国企业纳米碳酸钙生产工艺进行了比较。此外,还介绍了日本白石工业株式会社纳米碳酸钙产品在传统领域和新领域的应用。最后指出,中国企业只要严格控制纳米碳酸钙生产过程中的各个工序或环节、注重客户的使用效果、加大研发投入、积极开发新产品,中国纳米碳酸钙产品的质量会不断提升,达到世界先进水平。

Abstract:

Shiraishi calcium kaisha,Ltd.of Japan is the first enterprise to produce nano calcium carbonate in the world.With a wide range of products,excellent quality and a production capacity of 250 000 t/a,it is the world′s leading supplier of nano calcium carbonate.In order to understand the advanced production process of nano calcium carbonate abroad and provide ref-erence for the development of nano calcium carbonate industry in China,the production process of nano calcium carbonate of Shiraishi calcium kaisha,Ltd.was introduced in detail in this paper.The process or links of raw material selection,calcination,digestion,refining,carbonization,aging,surface treatment,pressure filtration,drying,crushing and packaging were described,and compared with the production process of nano calcium carbonate in domestic enterprises.In addition,the application of nano calcium carbonate products of Shiraishi calcium kaisha,Ltd.in traditional and new fields was also introduced.Finally,it was pointed out that as long as enterprises in China strictly controlled all processes or links in the production process of nano calcium carbonate,paid attention to the use effect of customers,increased R&D investment,and actively developed new products,the quality of nano calcium carbonate products would continue to improve and reach the world advanced level.

Key words: nano calcium carbonate, Japan, production process, product
