Applications of Nano Calcium Carbonate
Paper Industry
Nano calcium carbonate exhibits excellent dispersibility and low viscosity, making it a viable substitute for expensive kaolin to some extent, serving as an ideal high-grade paper filler. Incorporating nano calcium carbonate not only reduces costs but also enhances the strength, brightness, and smoothness of the paper. Additionally, it imparts superior folding flexibility, softness, and exceptional ink and water absorption capabilities.
Daily Necessities
It can be used as a filling material for high-end cosmetics, soap, cleaning agents, children's toothpaste and other daily necessities; With the continuous expansion of the development and application scope of nano calcium carbonate in China, the market prospects of nano calcium carbonate in China are very broad. In the future, through the research and modification of nano calcium carbonate, more excellent properties will be discovered, promoting the rapid development of China's calcium carbonate industry.
Rubber Industry
Nano calcium carbonate is currently the earliest and most widely used in the world.
A filler that not only increases product volume, saves raw materials, and reduces production costs, but also improves its process performance and enhances the product's resistance to tearing, compression deformation, bending, and other properties. In addition, nano calcium carbonate also has good effects in enhancing and whitening, and can be used to make transparent and semi transparent rubber products.
Plastic Industry
At present, the technology applied in the nano calcium carbonate industry in China is relatively mature. Nano calcium carbonate can increase the volume of products, reduce costs, improve stability, increase hardness and stiffness, improve the processing performance of plastics, enhance their heat resistance, improve their astigmatism and smoothness, enhance the impact resistance of tough cuts, and improve their viscosity during mixing.
Paint Industry
Due to its steric hindrance effect, it exhibits fine, uniform, excellent whiteness and optical properties in coatings. The present invention is suitable for manufacturing high-end car specific paint, which can increase the whiteness of the coating, improve the gloss and shielding properties of the coating.
The refinement of particle size, surface activation, and special structural morphology of nano calcium carbonate can improve its properties and broaden its application fields, which is the direction of development. By using suitable and efficient surface treatment agents and crystal shape adjusters to modify calcium carbonate, and then filling it into plastics, it can have good functionality and significant economic benefits. Simply using crystal shape control agents and modifiers to treat calcium carbonate has limited toughening effects on composite materials. Therefore, the search for a combination of crystal shape adjustment agents and surface modifiers is a highly promising modified calcium carbonate filling material.
Conclusion
In summary, nano calcium carbonate is a versatile and cost-effective functional material that significantly enhances performance across paper, rubber, plastic, paint, and daily chemical industries. Its ongoing surface modification and crystal-shape control are key to unlocking superior properties and expanding application frontiers. With continued R&D investment, nano calcium carbonate is poised to drive substantial growth and innovation in China’s materials sector, offering both economic and technical advantages for advanced manufacturing.
