HIGH REACTIVITY METAKAOLIN FOR CEMENT INDUSTRY(GB-HRM95/98)

Q: Do kaolin have blue and cyan?: Kaolin is mainly aluminosilicate, the main component of AL2 (Si2O5) (OH) 4, or written as Al2O3 2H2O 2SiO2

Q: How can we tell if there's kaolin in that hill?: It can be distinguished by its physical and chemical properties:Its characteristics: more non gloss, pure color, white and delicate, such as containing impurities can be gray, yellow, brown and other colors. According to the different causes of appearance is clod shape and dense state of loose rock block.

Q: The big ball of mud and kaolin porcelain which is good: The remnant of the large ball mud pegmatite is called kaolin. The ore has a big ball and a small ball. The big ball is 10-40 cm in diameter and the diameter of the ball is 3-4 cm. The size of a white mud ball, long hidden in the deep mountains and forests of Hunan Xiangxi, lived a secluded life underground". Thank you

Q: What is the best composition of kaolin?: Whiteness is one of the main parameters of kaolin's technological properties. Kaolin with high purity is white. Kaolin whiteness, natural whiteness, and whiteness after calcination. For ceramic raw materials, the whiteness of calcined is more important, the higher the whiteness of calcined, the better the quality. The ceramic process stipulates that the drying temperature is 105 degrees centigrade and the classification standard is the natural whiteness. The calcined 1300 DEG C is the grading standard for the whiteness of the calcined products. Whiteness can be measured by a whiteness meter. A whiteness meter is a device for measuring the reflectivity of 3800 - 7000 wavelength light. In the whiteness meter, the reflectivity of the sample to be measured is compared with the reflectance of the standard sample (such as BaSO4, MgO, etc.), i.e., the whiteness value (such as whiteness 90, which represents 90% of the standard sample reflectivity).

Q: Is kaolin soluble in water?The dispersion of kaolin in water is very unstable,At least stable 5-6 hours: 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. 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: What are the colors of kaolin ore?: Contains the quality is pale yellow, gray, green, black and other colors. The presence of these impurities, reduced the natural whiteness of kaolin, in which iron and titanium minerals will also affect the whiteness of the calcined, porcelain stains or scars appear.

Q: How can kaolin be removed from iron?: In addition to iron, the high gradient iron removal machine can remove most of the weak magnetic iron, which is very effective for some kaolin, and is also the most environmentally friendly and ideal process at present

Q: Who knows kaolin? Please, great God!: Most of them are crystalline, dispersed, powder and loose. White or light gray, light green, yellow, red and other colors, white streak, earthy luster. Mohs hardness of 2-2.5, the proportion of 2.6-2.63. Strong water absorption and water has plasticity, sticky tongue, dry lumps with rough feeling. Kaolinite is the main mineral of kaolin and is often found in the weathering crust of magmatic rocks and metamorphic rocks. China's famous kaolin producing areas are Jiangxi, Jingdezhen, Jiangsu, Suzhou, Hebei, Tangshan, Hunan, Liling and so on.

Q: Is it near the clay ore: Clay also known as kaolin, is the main raw material for ceramics. The clay is composed of metamorphic mica and feldspar, in which sodium and potassium, calcium and iron loss, water changes into.

Q: Hard kaolin in the ceramic piece, which is used in which? What's the difference between washed kaolin and washed kaolin?: First of all, calcined kaolin is calcined, crystalline and raw soil has changed; and washed kaolin is only physical treatment, will not change the properties of raw soil.
