Q: How to distinguish kaolin?: Therefore, kaolin has become the necessary mineral material for dozens of industries, such as paper making, ceramics, rubber, chemicals, coatings, pharmaceuticals and national defense. Kaolin is widely used in the paper making industry. There are two main areas. One is used in papermaking (or paper making), and the other is the pigment used in the surface coating process. Kaolin was first discovered in china.

Q: What's the difference between calcined kaolin and washed kaolin?: Calcined kaolin mainly refers to the hard kaolin (kaolinite), the original soil without adhesion, cannot be directly used as paper or refractory materials, after application of calcination; soil washed kaolin having adhesion, can directly do refractory binder or paper packing.As a filler of paper, the whiteness of calcined kaolin is very little, and the cost is relatively high

Q: What kind of kaolin can burn glazed tiles?: So you say the kaolin can burn tile, my answer is yes, but not necessary. A. can is because 1 tons of glazed tile clay, adding 1 kg of kaolin does not affect the product, but the reason is not necessary is to increase the cost of intangible kaolin.

Q: Application of kaolin: Because the calcined clay oil absorption value is relatively high, so the cosmetics industry recommends the use of ultrafine and high pure water wash soil, strict attention purity and heavy metal content of kaolin, these two aspects report report analysis and detection of heavy metals and chemical products, through the data report and compare its cosmetic requirements can be judged. Pharmaceutical industry bigger user base for butyl rubber plug industry, can use 1250 or so of calcined soil, this is more commonly used, usually as long as the heavy metal test qualified can use. The above two industries use kaolin price difference is quite big, the cosmetics class import product approximately RMB6 yuan /kg, the medicine class RMB2.2 yuan /kg.

Q: The difference between clay and porcelain: Porcelain clay, clay soil, Ge also powder, the more formal name is kaolin. Kaolin is a nonmetallic mineral, a kind of clay and clay rock mainly composed of kaolinite group clay minerals. Named after kaolin village, Jingdezhen, Jiangxi province. The quality of pure kaolin is white, fine and soft, and it has good plasticity and fire resistance. The mineral composition is mainly composed of mineral kaolinite, halloysite, illite, illite, montmorillonite and quartz, feldspar etc.. Kaolin is widely used, mainly used for papermaking, ceramics and refractories, secondly used in coating, rubber filler, enamel glaze and white cement raw materials, a small amount of paint, paint, plastic, used for grinding wheel, pencil, soap, cosmetics, pesticide, medicine, textile, petroleum, chemical industry, building materials, defense and other industrial sectors.

Q: How can clay sculptures not be cracked and preserved for a long time?: Kaolin, sculpture and other clay materials, after drying with water, there is a big contraction, which led to cracks. Do not want to crack

Q: How to distinguish the good or bad of kaolin?: Kaolin chemical composition analysis laboratory test kaolin composition is very complex, kaolin chemical composition contains a large number of AL2O3, SiO2 and a small amount of Fe2O3, TiO2, and trace amounts of K2O, Na2O, CaO and MgO.

Q: What is kaolin?: Kaolin is widely used in papermaking industry. There are two main areas, one is in the paper (or paper) in the process of using filler kaolin used in paper making, the paper can give good coverage performance and good gloss coating performance, but also increase the paper whiteness, opacity, smoothness and printing well, greatly improve the quality of the paper. The other one is used in surface coating process of paint.Kaolin formed by the combination of mud with water, under the action of external force deformation, external force is removed, the nature can still maintain this deformation is plasticity. Plasticity is the basis of kaolin in ceramic body molding process, is also the main technology indexes. Usually with plasticity index and plasticity index to indicate plasticity the size of the plasticity index refers to the moisture content minus plastic limit water content of kaolin clay material liquid limit, expressed as a percentage of the plastic index W =100 (W -W liquid limit and plastic limit). Forming plasticity index representative of kaolin clay material can be directly measured, crushing the mud ball load and deformation size with plastic instrument, kg cm said, often plasticity index is high, the better the performance of its forming.

Q: Who knows kaolin? Please, great God!: Kaolinite is a product of natural alteration of feldspar and other silicate minerals and is an hydrous aluminosilicate. It also includes dickite, nacrite and halloysite and similar components but amorphous allophane, so they belong to a called clay mineral.

Q: Kaolin with magnetic separator, how about iron?: Kaolin separator iron removal process is dry and wet dressing process method for magnetic separation of magnetite, in iron removal process, it can improve the reuse rate in the process of iron removal process, less water consumption, save water, reduce production costs, reduce pollution, dust and dust removal device with special magnetic separation, not air pollution is a kind of high production efficiency, good product quality, no environmental pollution process of creative.
