The modification process of nano-calcium carbonate can be divided into four types, namely, dry modification, wet modification, in-situ modification and composite modification. The modification process has a great impact on the modification effect, so it is very important to adopt suitable modification process for different application fields.

PVC is the abbreviation of PolyVinyl Chloride. It is a chemical product, with the scientific name of polyvinyl chloride.
