7 Major Application Fields and Characteristics of Nano Calcium Carbonate

Nano calcium carbonate refers to calcium carbonate products with particle sizes ranging from 1 to 100 nanometers. It exhibits surface effects, quantum size effects, and macroscopic quantum tunneling effects, which endow it with physical and chemical properties distinct from ordinary calcium carbonate, as well as special functional characteristics in various applications.

   1.Application of Nano Calcium Carbonate in the Rubber Industry
The rubber industry is the primary application market for nano calcium carbonate. It is used as a filler in rubber products in large quantities. Among rubber products, chain-like nano calcium carbonate is the most widely used, followed by cubic nano calcium carbonate.
In the rubber industry, nano calcium carbonate is mainly used in products such as tires. Adding nano calcium carbonate to rubber products can significantly improve elongation, tear resistance, compression deformation, and other properties. Additionally, the hardness of the products can be adjusted by varying the amount of calcium carbonate used.

   2.Application of Nano Calcium Carbonate in Plastic Products
The use of nano calcium carbonate in the plastics industry is well-established. While ordinary calcium carbonate primarily serves as a filler, nano calcium carbonate is mainly applied in high-end plastic products. Cubic nano calcium carbonate is the most widely used in plastics, characterized by low oil absorption, with an average particle size typically ranging from 0.1 to 0.5 micrometers.
Modified nano calcium carbonate offers significant advantages in plastic products: it improves heat resistance, hardness, and stiffness, enhances processing performance and smoothness, increases film toughness, transparency, and aging resistance, and improves the physical and mechanical properties of plastics.

   3.Application of Nano Calcium Carbonate in the Ink Industry
In the ink industry, nano calcium carbonate has become the most widely used filler material. Modified nano calcium carbonate is required in the ink industry, with spherical or cubic forms being the most commonly applied.
The advantages of using nano calcium carbonate in inks are notable, including high gloss and good stability. Research on nano calcium carbonate for inks has made significant progress in China.

   4.Application of Nano Calcium Carbonate in the Adhesive and Sealant Industry
The demand for structural adhesives and sealants is increasing. In silicone sealants, nano calcium carbonate primarily serves as a filler and reinforcing agent, with the cubic form being the most frequently used.
The application of nano calcium carbonate can significantly reduce costs while improving the processing and mechanical properties of the products.

   5.Application of Nano Calcium Carbonate in the Coatings Industry
Nano calcium carbonate holds great potential as a pigment filler in the coatings market. In coating applications, cubic or spindle-shaped nano calcium carbonate is generally required.
The use of nano calcium carbonate in coatings offers numerous advantages, such as making the coatings fine, uniform, and high in whiteness, while also preventing sedimentation. These benefits have led to its widespread adoption and use in the coatings industry.

   6.Application of Nano Calcium Carbonate in the Paper Industry
In the paper industry, nano calcium carbonate is used as a filler and offers many advantages, such as high opacity, good brightness and whiteness, and uniform, smooth paper quality. After special coating treatment, nano calcium carbonate can also be used in various high-end packaging papers.

   7.Application of Nano Calcium Carbonate in Lubricants
Nano calcium carbonate particles serve as lubricant additives, forming a protective film containing calcium carbonate on surfaces during friction. Nano calcium carbonate does not corrode metals or pollute the environment. When used in heavy oils with high sulfur content, it can neutralize sulfuric acid produced during combustion, providing a certain cleansing effect.
