Calcium Carbonate 100 Mesh Application: Uses, Benefits, and Industries

Introduction

Calcium carbonate (CaCO₃) is a widely used, versatile mineral that serves a variety of purposes across different industries. When ground to a particle size of 100 mesh, calcium carbonate offers specific characteristics that make it ideal for several applications. In this article, we will discuss 100 mesh calcium carbonate, its key properties, and the most common industries where it is applied.

What is 100 Mesh Calcium Carbonate?

100 mesh calcium carbonate refers to the calcium carbonate that has been ground into a fine powder with a particle size that passes through a sieve with 100 mesh openings per inch. The particle size of 100 mesh calcium carbonate typically ranges from 150 microns to 200 microns (0.15 to 0.2 millimeters). This mesh size is coarser compared to fine powders like 2000 mesh or 3000 mesh calcium carbonate but is still useful in various industrial applications, offering good dispersion and physical properties.

Key Properties of 100 Mesh Calcium Carbonate

• Particle Size: The relatively larger particle size compared to finer grades makes 100 mesh calcium carbonate ideal for certain applications, providing bulk without compromising strength.
• Purity: It is generally derived from high-quality natural limestone and provides a high level of purity, making it suitable for both industrial and food-grade applications.
• Non-Toxic: As a naturally occurring mineral, calcium carbonate is non-toxic, making it safe for many consumer and industrial uses.
• Color: It typically comes in a white or off-white color, contributing to the brightness and opacity in applications like paint and paper.

Applications of 100 Mesh Calcium Carbonate

1. Paint and Coatings Industry 100 mesh calcium carbonate is commonly used in the production of paints and coatings. Its relatively coarser particle size is ideal for use as a filler or extender. Some of its benefits in this application include:

• Opacity and Coverage: The coarser particles of 100 mesh calcium carbonate help to increase the opacity of the paint, allowing it to cover surfaces more effectively.
• Cost Reduction: It serves as a cost-effective filler, lowering the overall cost of paint production without sacrificing the performance of the coating.
• Improved Texture: It can improve the texture of the paint, giving it a smoother consistency and making it easier to apply.

2. Plastics Industry In the plastics industry, 100 mesh calcium carbonate is often used as a filler to improve the physical properties of plastic products. It is widely used in applications like PVC, polyethylene, and polypropylene-based products. The benefits in plastic manufacturing include:

• Improved Rigidity: The addition of calcium carbonate improves the rigidity and mechanical strength of plastic products, making them more durable.
• Cost-Effective: As a less expensive filler, it helps reduce production costs while maintaining good performance.
• Enhanced Processing: Calcium carbonate helps improve the flow properties during extrusion and molding processes, making plastics easier to process.

3. Paper and Pulp Industry 100 mesh calcium carbonate is used in the paper and pulp industry primarily as a filler and coating pigment. It offers several benefits for paper production:

• Brightness and Whiteness: It enhances the brightness and whiteness of paper products, improving their visual appeal.
• Opacity: The addition of calcium carbonate improves the opacity of the paper, allowing for better printability and reducing the use of high-quality raw materials.
• Bulk and Smoothness: Calcium carbonate increases the bulk of the paper without adding significant weight, providing a smooth finish that is ideal for printing and writing paper.

4. Rubber Industry In the rubber industry, 100 mesh calcium carbonate is often used as a filler in the production of various rubber products, such as tires, seals, gaskets, and hoses. The key benefits of using calcium carbonate in rubber include:

• Improved Strength and Durability: Calcium carbonate increases the strength, wear resistance, and durability of rubber products, making them more effective in various applications.
• Cost-Effective: Calcium carbonate is an inexpensive filler that helps reduce the cost of producing rubber products without compromising quality.
• Improved Processing: It helps improve the processing characteristics of rubber, making it easier to handle during production.

5. Construction Industry In the construction industry, 100 mesh calcium carbonate is used in various building materials such as cement, mortar, plaster, and grouts. The benefits of using calcium carbonate in construction include:

• Improved Strength: Calcium carbonate improves the compressive strength of cement and concrete, making structures more durable.
• Cost Efficiency: As a filler material, it reduces the cost of cement production while enhancing the material's performance.
• Better Workability: The presence of calcium carbonate in plaster and mortar improves the workability and texture, making it easier to apply and spread.

6. Animal Feed and Agriculture 100 mesh calcium carbonate is used in both animal feed and agriculture for various purposes:

• Calcium Supplement: In animal feed, it serves as a source of calcium, promoting strong bones and proper metabolic functions in livestock.
• Soil Amendment: In agriculture, it is used as a soil conditioner to correct acidic soils by raising the pH and improving soil structure.

7. Pharmaceuticals and Food Industry Calcium carbonate is used in the pharmaceutical and food industries as a dietary supplement and antacid. 100 mesh calcium carbonate is often used in:

• Antacids: Calcium carbonate is commonly used as an ingredient in over-the-counter antacid tablets.
• Calcium Supplement: It is used in food-grade applications to fortify products with calcium.
• Coloring Agent: It may be used as a coloring agent in food processing, contributing to the opacity and brightness of certain food products.
