Nano calcium carbonate: also known as super fine calcium carbonate, the standard name is superfine calcium carbonate. Nanoscale calcium carbonate is an inorganic compound with a molecular formula of CaCO3 and a relative molecular mass of 100.09. Calcium oxide (CaO) accounted for 56.03%, and carbon dioxide (CO2) accounted for 43.97%. Nano calcium carbonate (CaCO 3) is a kind of calcium carbonate powder with small physical size, and its particle size is at 0.03 microns in general. Nano calcium carbonate is processed on the basis of ordinary calcium carbonate. It is more important than ordinary calcium carbonate. It is an important nonmetallic mineral.
The most mature industry for the application of nano calcium carbonate is that the plastics industry is mainly used in high-grade plastic products. The PVC plasticsol, which is used for the internal seal of the automobile, can improve the rheological property of the plastic masterbatch and improve its formability. As a plastic filler, it has the function of toughening and strengthening, improving bending strength and bending modulus, thermal deformation temperature and dimensional stability of plastics, as well as giving plastic thermal hysteresis.
Nanomaterials must have two conditions, (1): for the size of 1 100nm, (2): for its application is due to its small particle size and bring about the change of property. The size of nano CaCO 3 is usually 20-100Nm, and its particle size is small, which makes it reflect many properties that ordinary materials do not possess in practical application. Therefore, nano calcium carbonate is a kind of nanomaterial that has fully realized industrialization now.
As far as the development of nanometer calcium carbonate is concerned, it is still a relatively low content of nanomaterials, but it also indicates that nanomaterials are actually not far from our life.
