Q:What's the difference between kaolin and clay?
Clay:A hydrous aluminosilicate mineral that is a widely distributed colloidal, amorphous, cohesive soilIt is plastic when wet and hard when it is bakedIt is mainly composed of igneous and metamorphic rocks is decomposed, consisting essentially of kaolin and other minerals in bauxite.Clay has a unique plasticity and bonding properties, that is, molding properties and firing propertiesConclusion: clay ceramic material is a hydrous aluminum silicate minerals, from feldspar rock through long-term weathering and geological formation. It is a mixture of many fine minerals, the main chemical composition of two aluminum oxide and silicon dioxide, three crystal water, with a small amount of alkali metal, alkaline earth metal oxides and oxide coloring. Clay has a unique plasticity and binding, the water swelling can be kneaded into mud, shaping the required shape, after roasting becomes hard and compact. This performance, form the basis of the ceramic production process. Clay is the basic material of pottery and porcelain production, widely distributed in nature, large reserves. Variety, is a valuable natural resource.
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 whiteness, soft, easy to disperse in water, suspension has good plasticity and high adhesion, excellent electrical insulation properties and good acid soluble cationic, low resistance and other physical quantity, exchange of good properties. The clay minerals and clay minerals, with many excellent technical characteristics. Such as: water absorption, plasticity, strong adhesion, high refractoriness, good insulation and chemical stability, but also has good sintering properties in 1365 DEG C to form white blank, no deformation.
Q:How can kaolin be removed from iron?
Except for iron, some of them are added with insurance powder, but they are very polluted to the environment, and they may not be used in the future. They may be banned later4, in addition to biological and magnetic in Tiefa Tiefa currently in the research stage, is not very mature.
Q:What's the difference between kaolin and white mud?
The mining methods of kaolin ore include open pit mining and underground mining. Weathered residual kaolin ore is widely mined, such as sandy kaolin in Maoming. Other hydrothermal altered and sedimentary deposits are mined by open pit and underground by deep mining. The open-pit mines, but most are small and medium-sized mines, large Fujian Longyan kaolin company, Guangdong company, Guangdong Maoming southern Maoming kaolin kaolin company. Suzhou Chinese kaolin company owned mining, Yangdong mine Yangxi used in open-pit mining. Large scale underground mining are: Jiangsu Suzhou Yangxi shaft, shaft, the white Shanling Guanshan Yangdong mine and Wuxian Qingshan white clay ore etc..
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:What are the functions of kaolin? What areas of industry are you using?
White, soft, high dispersibility, adsorption and chemical compatibility, which make it widely used in the paper industry. In addition, kaolin in rubber, plastics, refractory materials, petroleum refining and other industrial sectors, as well as agricultural and national defense, cutting-edge technology also has a wide range of uses.
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:What are the colors of kaolin ore?
The color of kaolin is mainly related to its metal oxides or organic matter.
Q:Can kaolin be used for cosmetics?
Kaolin is mainly composed of two oxygen silicon and three aluminum oxide two. Do high-end cosmetics, kaolin requirements of pure white, fine granularity (1250 mesh).
