中国是世界上石灰岩矿资源丰富的国家之一。碳酸钙可用于造纸工业,能有效的提高纸的白度和不透明度,改进纸的平滑度、柔软度,改善油墨的吸收性能,提高保留率。随着造纸工业的发展,植物纤维的需求日益增大,对生态环境的破坏日益严重。研究碳酸钙在造纸中的应用能有效地减少环境污染,保护生态环境。并且叙述淀粉改性碳酸钙对填料的影响。
China is one of the countries rich in limestone and mineral resources in the world. Calcium carbonate can be used in the paper industry, can effectively improve the whiteness and opacity of the paper, improve the smoothness of the paper, softness, improve the absorption of ink, improve retention. With the development of papermaking industry, the demand of plant fiber is increasing day by day, and the damage to the ecological environment is increasingly serious. Research on the application of calcium carbonate in papermaking can effectively reduce the environmental pollution and protect the ecological environment. The effects of starch-modified calcium carbonate on fillers are also described.
