Basic concepts of nano calcium carbonate

Nano calcium carbonate: also known as ultra-fine calcium carbonate, the standard name is ultra-fine calcium carbonate. Nano calcium carbonate is an inorganic compound, its molecular formula is CaCO3, the relative molecular weight is 100.09. Calcium oxide (CAO) and carbon dioxide (CO2) accounted for 56.03% and 43.97%, respectively. Nano calcium carbonate is a kind of calcium carbonate powder with small physical particle size, and its particle size is generally 0.03 μ M. Nano calcium carbonate is obtained by processing on the basis of ordinary calcium carbonate, which has stronger performance than ordinary calcium carbonate and is an important non-metallic mineral.

The mature industry of nano calcium carbonate is plastic industry, which is mainly used in high-grade plastic products. The PVC plasticized sol used for automobile interior sealing can improve the rheology of plastic masterbatch and its formability. As a plastic filler, it has the function of toughening and reinforcing, improving the bending strength and modulus of elasticity, thermal deformation temperature and dimensional stability of plastics, and endowing the plastic with thermal hysteresis.

"Nanomaterials" must have two conditions: (1) the particle size is between 1-100nm, (2) the properties of nanomaterials are changed due to their small particle size in their applications. The particle size of nano calcium carbonate is usually 20-100Nm, and because of its small particle size, it reflects the performance that many ordinary materials do not have. Therefore, it is certain that nano calcium carbonate is a kind of nano material that has been industrialized at present.

In terms of the current development of nano calcium carbonate, it is still a kind of nano material with relatively low technology content, but it also shows that nano materials are not far away from our life.
