[0002] Nano calcium carbonate is also called ultrafine calcium carbonate. The standard name is ultrafine calcium carbonate. The most mature industry for the application of nano calcium carbonate is the plastics industry, which is mainly used in high-end plastic products. It can improve the rheological properties of plastic masterbatch and improve its formability. It can be used as a plastic filler to strengthen and toughen the plastic, improve the bending strength and bending elastic modulus, heat deformation temperature and dimensional stability of the plastic, and also give the plastic thermal hysteresis. Nano calcium carbonate used in ink products reflects excellent dispersibility and transparency and excellent gloss, as well as excellent ink absorption and high drying properties. Nano calcium carbonate is used as an ink filler in resin-based inks, and has the advantages of good stability, high gloss, no effect on the drying properties of printing inks, and strong adaptability.
