Product Details
Kaolin(China clay)
kaolin is white, delicate, soft soil, with good plasticity and fire resistance and other physical and chemical properties. Its mineral composition is mainly composed of kaolinite, Eloite, hydromica, illite, montmorillonite, quartz, feldspar and other minerals. Kaolin is widely used, mainly for paper making, ceramics and refractory materials, followed by paint, rubber fillers, enamel glaze and white cement raw materials, a small amount of plastic, paint, pigment, grinding wheel, pencil, daily cosmetics, soap, medicine, textile, petroleum, chemical, building materials and other industrial sectors.
