纳米碳酸钙是一种新型超细功能材料,是最廉价的纳米改性剂,广泛应用于橡胶、塑料、涂料、胶粘剂、造纸、油墨、医疗等领域,还有许多用途有待开发,因此已成为当前纳米材料领域竞相研究和开发的热点。我国已可生产五、六个型号的纳米碳酸钙产品,但高档纳米碳酸钙产品尚需进口。河 Nanocrystalline calcium carbonate is a new type of ultrafine functional material and is the cheapest nanometer modifier. It is widely used in rubber, plastic, paint, adhesive, papermaking, ink and medical treatment. There are many applications to be developed and it has become The current nanomaterials competing in the field of research and development of hot spots. China has been able to produce five or six types of nano-calcium carbonate products, but still need to import high-grade nano-calcium carbonate products. River
