Application advantages of nano calcium carbonate
With the progress of materials science, nano calcium carbonate has played an unparalleled advantage over ordinary calcium carbonate due to its unique ultra-fine crystal structure and surface electronic structure. Its quantum size effect, small size effect, surface effect and other characteristics make nano calcium carbonate show great advantages in dispersibility, reinforcement effect, functionality and cost control, and become an important choice for engineering plastic modification.
Nano calcium carbonate can not only increase the volume of plastic products, improve hardness and strength, but also improve performance indicators such as heat resistance, bending strength and elastic modulus. Ultrafine wet-ground heavy calcium carbonate can replace 20% to 30% of organic pigments, which not only improves performance but also reduces costs. Adding ultrafine heavy calcium carbonate to PE and PP composite materials can maintain the same tensile strength as light calcium carbonate, while improving bending strength and impact strength, and better processing fluidity.
Summary
The versatility of calcium carbonate in plastic processing is not only reflected in improving the performance of plastic products and reducing costs, but also further enhances the market competitiveness of products. With the development of nano calcium carbonate technology, its application prospects are broader and will play a more important role in the future plastics industry.
