Calcium carbonate is an inorganic compound with chemical formula of CaCO₃. It is the main component of limestone and marble, and it is widely used in industries of paper-making, metallurgy, glass, alkali, rubber, medicine, pigment and organic chemistry. Surface modification is an important means to improve the application performance of calcium carbonate. So, what are the benefits of surface modification of calcium carbonate? Next, Let’s analyze it together.
Benefits of surface modification of calcium carbonate
1. Improve the dispersibility of calcium carbonate
Through surface modification, the modifier can adsorb on the surface of calcium carbonate, making the surface charged. Due to the repulsion of the same charge, calcium carbonate is hard to agglomerate, thereby achieving good dispersion.
2. Improve the compatibility of calcium carbonate
Surface modification can improve the compatibility of calcium carbonate. The main reason is that the modifier can form an organic coating on the surface of calcium carbonate. This coating changes the surface properties of calcium carbonate, and enhances its compatibility with organic polymers or resins.
3. Endow calcium carbonate functionality
Through surface modification, calcium carbonate can be transformed from ordinary filler material into multifunctional modifier. For example, calcium carbonate coated with silica can partially replace white carbon black, and make up for the deficiencies of white carbon black in certain properties.
4. Reduce oil absorption of calcium carbonate
Surface modification reduces oil absorption value by changing the surface properties and dispersion state of calcium particles. Specifically, it reduces the gaps between particles and enhances the lubricity between particles.
