July 31 news, Heavy calcium carbonate, a powder material processed from natural minerals such as calcite and marble, plays a crucial role in various industrial sectors. Having a comprehensive understanding of its application fields and requirements is essential for corporate product planning and technology development.
In the paper industry, heavy calcium carbonate serves as a vital filler and coating pigment. It significantly enhances the opacity, brightness, and smoothness of paper while reducing moisture absorption and deformation. This not only improves the printing performance of the paper but also lowers production costs. Developed countries in Europe often opt for high-purity, high-whiteness chalk as the preferred raw material to ensure paper quality.
The plastics industry is the largest consumer of heavy calcium carbonate. Adding calcium carbonate to plastics like polyvinyl chloride (PVC) and polyethylene (PE) enhances the dimensional stability, hardness, and rigidity of the products. It also improves processing performance, heat resistance, and light scattering properties.
In the coatings industry, heavy calcium carbonate is a widely used extender pigment that plays a structural and leveling role, significantly improving coating performance. Calcium carbonate of different particle sizes has varying effects in coatings. For instance, ultra-fine heavy calcium carbonate can significantly reduce sanding time and enhance the covering power and viscosity of the coating.
Furthermore, in the rubber industry, heavy calcium carbonate primarily functions as a filler, increasing the stiffness of the rubber compound, improving electrical insulation, and reducing production costs. In the production of breathable membranes, the addition of special calcium carbonate is a key factor affecting their performance.
Heavy calcium carbonate also finds applications in food additives, pharmaceuticals, toothpaste, animal feed, and artificial stone. In the pharmaceutical industry, it’s commonly used as a drug filler to maintain drug stability through its anti-acid effect. In toothpaste, it serves as a friction agent, enhancing cleaning effectiveness. In animal feed, it acts as a calcium source for bone development. And in the field of artificial stone, heavy calcium carbonate powder is the primary filler, significantly reducing production costs and enhancing environmental performance.
According to the Color Masterbatch Industry Network, with technological advancements, the application fields of heavy calcium carbonate will continue to expand, further highlighting its critical role in various industries. Therefore, for businesses, having a comprehensive understanding of calcium carbonate’s application areas and requirements will aid in better product planning and technology development, adapting to market demands and enhancing competitiveness.
