1. Introduction to Coated Precipitated Calcium Carbonate

Coated precipitated calcium carbonate (PCC) has emerged as a versatile additive across numerous industries. Its unique properties make it an invaluable resource in enhancing the performance of various products. In this article, we will delve into the myriad benefits of coated PCC, exploring its manufacturing process, applications, and future trends.
 

2. What is Coated Precipitated Calcium Carbonate?

Coated precipitated calcium carbonate is a refined form of calcium carbonate that undergoes a precipitation process, followed by a coating process with substances such as stearic acid. This coating enhances its surface characteristics, improving its compatibility with polymers and other materials. The result is a product that boasts superior dispersion, lower viscosity, and better UV stability, making it an ideal choice for various applications.
 

3. The Manufacturing Process of Coated PCC

The production of coated PCC involves several critical steps:
1. **Precipitation**: Calcium carbonate is precipitated from a solution containing calcium ions and carbonate ions. This involves the controlled reaction of these ions in a reactor to form fine calcium carbonate particles.
2. **Washing and Filtration**: The precipitated calcium carbonate is then washed to remove impurities and unreacted materials. After washing, it is filtered to obtain a concentrated slurry.
3. **Drying**: The slurry is dried to produce a fine powder of precipitated calcium carbonate.
4. **Coating**: In this step, the dry PCC powder is coated with agents like stearic acid. This process enhances the hydrophobic properties of the carbonate, improving its performance in various applications.
5. **Quality Control**: The final product undergoes rigorous quality control measures to ensure it meets industry standards and specifications.
