CALCINED KAOLIN FOR PAPER MAKING(GB-CK98L/D)

Q: Do kaolin have blue and cyan?: Some trace metal elements which may be a different color, the specific color and the metal or metal oxide flame color color

Q: Are there any differences between bentonite and kaolin?: Bentonite (Bentonite) predominantly montmorillonite aqueous clay minerals. The chemical composition of montmorillonite: (Al2, Mg3) Si4O10 OH2 nH2O, because it has special properties such as swelling, adhesion, adsorption, catalysis, thixotropy, suspension and cation exchange. So widely used in various industrial fields.

Q: Who knows the value of the raw ore of this kind of kaolin? How much is it?: For example, plasticity; in addition, whiteness has a difference between natural whiteness and burnt whiteness...... So there are more indicators to be provided, so few indicators are estimated that no one can answer.

Q: How do porcelain mud distinguish good or bad?: The difference between the mines leads to uneven composition and leads to inconsistent quality. The loss of many mud and glazes in China is very important for this reason.

Q: I only know that is a kind of raw material, and sell them where to sell, and I can have to contact the white mud!: There are reports that Japan has also used kaolin instead of steel, cutting tools, lathes, drills, and internal combustion engines. Especially in recent years, the rapid development of modern science and technology, the application of kaolin is more extensive, began extensive use of kaolin as new materials in some high-tech fields, and even nuclear reactor space aircraft and spacecraft components with high temperature porcelain, made of kaolin.

Q: What are the colors of kaolin ore?: The color of kaolin is mainly related to its metal oxides or organic matter.

Q: Which mixer can be more evenly dispersed kaolin slurry?: If you love to drink fruit juice drinks of all kinds, so it is recommended to select with mixer speed regulation, so that you can freely adjust the stirring speed, some fruit juice does not need to stir too broken to drink. Therefore, you can choose a mixer with speed control function.

Q: What is the significance of the target in kaolin?: The project refers to the kaolin kaolin through the screen mesh. The purpose is defined as the number of holes per square inch mesh. 200 mesh for each square powder particle size known particle size. As the particle shape is very complex, usually there are several screening methods, such as particle size, sedimentation particle size, equivalent volume size, equivalent surface area, particle size and so on.

Q: What are the uses of calcined kaolin?: At present, the global total output of about 40 million tons of kaolin (the data belonging to the simple country and production together, in which no statistical ore trade volume, including more repeat calculation), which is about 23 million 500 thousand tons of refined soil. Paper making is the largest consumption Department of refined kaolin, accounting for about 60% of total consumption of kaolin. According to data provided by Temanex consulting Canada, the total output of paper and paperboard in the world was about 319 million tons in 2000, and the total amount of kaolin used in the world's paper coating was about 13 million 600 thousand tons. For general cultural paper, the amount of filling accounts for 10-20% of the weight of the paper. For coated paper and paperboard (mainly light weight coated paper, coated paper and coated paperboard), in addition to filling, pigments are required, and the proportion of kaolin used to fill the pigment is 20-35% of the weight of the paper. 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 printability, greatly improve the quality of the paper.

Q: The difference between calcined clay and calcined kaolin: Also known as clay kaolin clay, clay, generally translated, is a content of kaolinite origin rocks have reached more than the amount of which is the final product of granite and feldspar weathering, is the main component of hydrated aluminium silicate. Catalpo rubber old called crushing natural product is refined, the price is low.
