Plastics are easy to burn and produce toxic gases when burning. For example, when polystyrene is burned, toluene will be produced. A small amount of this substance will cause blindness, vomiting and other symptoms when inhaled. PVC burning will also produce toxic hydrogen chloride gas. In addition to burning, which is high temperature environment, plastic will decompose into toxic components, such as benzene.

Kaolin is widely used, mainly for paper making, ceramics and refractory materials, followed by coatings, rubber fillers, enamel glazes and white cement raw materials, and a small amount for plastics, paints, pigments, grinding wheels, pencils, daily cosmetics, soap, pesticides, pharmaceuticals, textiles, petroleum, chemicals, building materials, national defense and other industrial sectors.

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.
