- Plastics: Adds aesthetic value with bright surfaces and improves UV resistance.
Factors Affecting Whiteness
1. Quality of Raw Materials (Natural Limestone):
- The whiteness of CaCO3 Powder depends largely on the purity of the raw limestone.
- Limestone with high calcium carbonate (CaCO3) content and low impurities is essential for ensuring natural whiteness.
- In Vietnam, limestone from Nghe An and Thanh Hoa is renowned for its exceptional whiteness.
2. Impurities (Iron, Silica, Magnesium):
- Impurities like iron oxide (Fe2O3) and magnesium oxide (MgO) reduce whiteness and affect the quality of CaCO3 Powder.
- Processes such as filtering and washing raw materials before grinding help remove some impurities and preserve natural whiteness.
3. Geographical Location and Mine Properties:
- Geological factors determine the chemical composition and structure of limestone.
- Limestone mines in different parts of the world vary in whiteness, giving Vietnam a competitive edge in the global market.
By combining the natural advantages of high-quality resources with modern technology, Global Minerals not only preserves but also optimizes the whiteness of CaCO3 Powder, meeting the diverse demands of global industries.
