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 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 (kaolin ore mainly includes light weight coated paper, coated paper and paperboard), in addition to the packing, also need to fill, pigment, pigment with kaolin accounted for paper weight 20-35%. 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. The main production of ceramic white mud to local sales.

Q:Heroes, help me see if this is quartz sand or kaolin? Is it valuable?

With the above coating will be very fine of 600, 800, less is known regarding the paint application; glass quartz sand in general about 140 items, including water glass, in the East China area for water glass quartz sand price is 400~600 yuan; can also be directly or directly sold to dozens of pieces (ceramic factory the added value is not high), direct selling feel a little waste of resources.

Q:The big ball of mud and kaolin porcelain which is good

Big balls are much better than kaolin. A big ball of mud is very rare only two places in the world, one is in Britain during the second world war has been mined over, one is in Chinese Hongjiang, the big ball of mud in the last century at the end of 70s has exhausted its scarce precious mining, known as the "gold mud".

Q:Does kaolin ore hazard do harm to human body?

Kaolin is a major component of clay minerals. It is rich in silicon, zinc, magnesium, aluminum and other minerals. The chemical elements are simple: AL4 (Si4O10) OH6, in addition to alumina, silica is also included.

Q:How to distinguish kaolin?

It is a used porcelain porcelain, also called white clay, commonly referred to as gaoling. The chemical formula for kaolin is Al2O3 (alumina) 2SiO2 (silica) 2H2O (water). That is to say, kaolinite is hydrous silicate. Secondly, kaolinite does not dissolve in water. Other than hydrofluoric acid, it can not be dissolved by other acids, which is one of its characteristics. To distinguish kaolinite, mineral analysis methods can also be used. 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. kaolin

Q:What are the uses of calcined kaolin?

Pure kaolin with high whiteness, soft, easy to disperse in water, suspended in plasticity and good adhesion, high excellent electrical insulation properties; has good acid soluble cationic, low resistance and other physical and chemical properties, better exchange. Therefore, kaolin has become the necessary mineral material for dozens of industries, such as paper making, ceramics, rubber, chemical, coating, medicine and national defense.

Q:This is a stone dug with kaolin. Does anyone know what it is?

The stones dug together with kaolin are quartzite,

Q:The difference between kaolin and talc in rubber

Talc powder, English name PULVISTALCI, white or white like, fine, sand free powder, hand touch greasy. Odorless, tasteless. This product is insoluble in water, dilute ore, acid or dilute hydrogen alkali solution. This product is magnesium silicate mineral!

Q:Where are the main differences between kaolin and kaolinite?

Kaolin pure white, because of impurities can be dyed other colors. Aggregate dull or waxy. Extremely cleavage, hardness 2.0~3.5, relative density 2.60~2.63. Dense block with a rough sense, dry with water absorption, wet state of plasticity, but water does not expand.

Q:What is the difference between diatom mud and kaolin?

Diatom mud is the diatom after the death of the diatom plants in the sea. The diatom formed by the precipitation of the corpse for thousands of years. It forms diatomite after the diatom ore is purified, and the diatom mud can be formed on the upper wall after processing according to the formula proportion.
