Light calcium carbonate, also known as precipitated calcium carbonate (PCC), is a fine powder produced through chemical processing methods, with the chemical formula CaCO₃. Its main difference from heavy calcium carbonate lies in the production method and particle size; light calcium carbonate has finer particles and a larger settling volume.

Details Introduction

Light calcium carbonate, also known as precipitated calcium carbonate (PCC), is a fine powder produced through chemical processing, with the chemical formula CaCO₃. Its main difference from heavy calcium carbonate lies in the production method and particle size; light calcium carbonate has finer particles and a larger settling volume.

Product characteristics:

Chemical formula: CaCO₃

Settling volume: 2.4-2.8 mL/g

Solubility: Almost insoluble in water, but forms a suspension in water, with a pH range of 9.5~10.2

Chemical reactivity: Reacts with all strong acids to produce corresponding calcium salts and release carbon dioxide

Color: Usually white

Relative density: 2.7~2.9

Specific surface area: About 5 m²/g

Application industries:

Light calcium carbonate is widely used in various fields due to its unique physical and chemical properties:

Papermaking: Used as a filler to increase the whiteness and opacity of paper

Plastics: Used as a filler to improve the mechanical properties of plastics and reduce costs

Coatings and paints: Enhances the coverage and gloss of coatings

Rubber: Improves the hardness and wear resistance of rubber products

Cosmetics: Used as an additive in whitening and sunscreen products

Food industry: Used as a food additive, for example in chewing gum and chocolate

Pharmaceuticals: Used as a filler and antacid in drug formulations

Application in brake pads:

In brake pads, light calcium carbonate is commonly used as a filler, which can help:

Increase friction coefficient: Brake pads need to generate sufficient friction to slow down or stop the vehicle during braking, and light calcium carbonate helps maintain an appropriate friction coefficient.

Enhance wear resistance: The high temperatures and wear generated during braking require brake pad materials to have high wear resistance, and light calcium carbonate helps improve the durability of brake pads.

Reduce noise: Fine calcium carbonate powder can reduce vibrations and noise during the braking process.

Improve thermal stability: The high thermal stability of light calcium carbonate allows it to maintain structural stability under high-temperature conditions, helping brake pads maintain performance during continuous braking.

Overall, the application of light calcium carbonate in brake pads is primarily aimed at enhancing the performance of brake pads, ensuring the safety and reliability of braking.
