Use Of Calcium Carbonate In Paper Industries

In paper and board, a broad range of tailored precipitated and ground calcium carbonate solutions providing cost efficiencies as well as optical and physical performance characteristics in a wide range of paper and board applications. YAMUNA CALCIUM® gives paper maximum whiteness and opacity, increases volume, and improves printability, when used in the paper pulp and in the paper coating. A large range of fillers and coating pigments for best whiteness, printability and cost effective fiber substitution.

We offer a wide range of carbonate products that differ in particle size, particle size distribution and brightness to suit all Paper and Board application needs.

Precipitated Calcium Carbonate (PCC) is produced through a chemical reaction process that utilizes calcium oxide (quicklime), water and carbon dioxide to produce very pure calcium carbonate crystals. Through the reaction process, the crystals can be tailored to a variety of shapes and sizes to best fit a customer’s required performance.

Ground Calcium Carbonate (GCC) is composed of the crystalline mineral calcite, which occurs naturally in the form of chalk, marble or limestone. Chalk is usually fine-textured and varies in colour from deposit to deposit. Marble gives products of the highest brightness and lowest yellowness.

Both PCC and GCC are commonly used in many types of paper, both as fillers within the paper structure as well as a coating on the surface. They are particularly prized as cost-effective Fiber and TiO2 replacements in papermaking.

Application-specific benefits

  • * High whiteness, brightness and opacity
  • * Adaptable rheology
  • * Improved printability
  • * Cost-effective fibre and TiO2 replacement

Uses of Calcium Carbonate in Paper Industry:

1) Brightness and Whiteness: Calcium carbonate improves the brightness and whiteness of paper, enhancing its appearance and printability.

2) Smoothness: It imparts a smooth surface to the paper, making it suitable for high-quality printing.

3) Opacity: It increases the opacity of the paper, making it less transparent and improving its readability..

4) Economical: Using calcium carbonate as a filler can reduce the overall cost of paper production. It is cheaper compared to other materials and helps in reducing the usage of expensive fiber.

5) Eco-Friendly Production: The production process of calcium carbonate is less harmful to the environment compared to other fillers like clay.

Advantages of Calcium Carbonate:

1) Improved Quality: Enhances the physical properties of paper, making it more durable and resistant to wear and tear.

2) Versatility: Can be used in various types of paper, including printing paper, writing paper, and packaging materials.

3) Resource Efficiency: Helps in conserving natural resources by reducing the need for wood pulp, thereby aiding in forest conservation.

4) Recyclability: Paper containing calcium carbonate is easier to recycle and can be repurposed for various uses.
