The selection of suitable kaolin clay needs to consider the following factors:
1. Particle size: According to your needs, choose the appropriate particle size. Generally speaking, kaolin with finer particles is suitable for the production of delicate crafts such as ceramics and coatings, while kaolin with coarse particles is suitable for the production of ceramic bricks, ceramic pipes and other building materials.
2. Impurities: Impurities in kaolin will affect its performance, so it is necessary to choose kaolin with less impurities. Generally speaking, high-purity kaolin is suitable for the production of high-quality ceramic products.
3. Mineral composition: Different kaolin contains different mineral composition, which will affect its sintering performance, plasticity and other characteristics. According to the specific process requirements, kaolin containing suitable mineral composition is selected.
4. Origin and supplier reputation: select reputable suppliers to ensure the quality and stability of kaolin.
Considering the above factors, suitable kaolin clay can be selected for specific process production.
