High Whiteness Ground Calcium Carbonate
Ground calcium carbonate, also known as heavy calcium carbonate.Ground calcium carbonate is made by grinding natural carbonate minerals such as calcite, marble, limestone. The shape of heavy calcium carbonate is irregular, the particle size difference is large, and the particles have a certain edge, the surface is rough, the particle size distribution is wide, the particle size is large, the average particle size is generally 1~10μm.
Ground calcium carbonate plays a crucial and extensive role in the paper - making industry. The following is a detailed account of its applications:
Ground calcium carbonate (GCC) is a widely used mineral filler in the paper industry, renowned for its ability
to enhance paper brightness and opacity.
1. High Brightness and Whiteness: GCC offers exceptional brightness and whiteness levels, typically above 90%, which can significantly improve the visual appeal of paper products. This is crucial for applications where aesthetics and readability are paramount, such as printing and packaging.
2. Opacity Enhancement: GCC particles effectively scatter light, increasing paper opacity. This makes GCC an ideal choice for producing high-quality printing papers that minimize show-through and ensure clear, distinct images and text.
3. Cost-Effective Solution: GCC is abundant and relatively inexpensive, making it a cost-effective alternative to other fillers. It allows paper manufacturers to reduce raw material costs while maintaining or improving paper quality.
4. Improved Printability: GCC enhances paper's ink absorption capabilities, leading to better ink holdout and faster drying times. This results in sharper, cleaner prints and reduced ink smearing, which is essential for high-speed printing processes
5. Environmental Benefits: GCC is a naturally occurring, renewable resource. Its use in paper production reduces the reliance on forest-derived fibers, contributing to sustainability and reducing environmental impact.
6. Consistency and Reliability: GCC's consistent particle size distribution and chemical purity ensure uniform filler dispersion in paper pulp, leading to consistent paper quality and performance.
