What is the function of imported kaolin?

1. Industrial use

Imported kaolin has become a necessary mineral raw material for dozens of industries such as papermaking, ceramics, rubber, chemicals, coatings, pharmaceuticals, and national defense;

Ceramics not only have strict requirements for the plasticity, adhesion, dry shrinkage, dry strength, sintering shrinkage, sintering properties, fire resistance, and post firing whiteness of imported kaolin, but also involve chemical properties, especially the presence of chromogenic elements such as iron, titanium, copper, chromium, and manganese, which reduce the post firing whiteness and cause mottling.

2. Edible

In the old society and the Great Chinese Famine, the poor often lived on Guanyin soil during the lean years or famine years; This kind of soil can be eaten to the stomach, but it cannot be digested and absorbed by the human body. After eating it, it will cause bloating and difficulty in defecating. Eating a small amount of it is not fatal; Although not hungry, due to lack of nutrients.

Imported kaolin mineral deposits are composed of Kaolinite, dickite, pearl stone, halloysite and other Kaolinite cluster mineral deposits, and the primary mineral component is Kaolinite.

The imported kaolin mineral deposits belong to 1:1 layered silicate, and the crystal is mainly composed of silica tetrahedron and hydrogen oxygen Octahedron. The silica tetrahedron is connected along the two-dimensional direction by sharing the vertex angle to form a hexagonal grid layer;

The pointed oxygen that is not shared by each silicon oxygen tetrahedron faces one side; The 1:1 type unit layer is composed of silicon oxygen tetrahedron layer and oxygen attracting Octahedron layer, which share the silicon oxygen tetrahedron layer.
