CALCINED KAOLIN FOR CABLE (GB-CK90) National Standard Quality

Q: How to remove the kaolin from the stone?: Ordinary stone mainly silicate compound, hard texture and resistance to acid and alkali; and kaolin molecular formula Al2O3-2SiO2-2H2O, whether or not alumina, silicon oxide, alkaline, so only a small amount of NaOH can be removed through kaolin;

Q: What is the difference between diatomite and kaolin? Thank you: The main component of kaolin is 2Si02 2H20 Al203, is the most dense or loose soil. Easily dispersed in water or other liquids, soapy, earthy. Having plasticity; wet soil can be molded into various shapes without breaking, and can remain unchanged for a long time. Is a kind of non metallic minerals is ubiquitous in nature, are used to produce ceramic, refractory materials and a small amount of mixed plastics, rubber filler in law. It is widely used in ceramics, rubber, plastics, artificial leather, cement, refractory materials, chemical industry and agriculture.

Q: High silica kaolin is?: High silica (also known as quartz, silica, silica, silicone soft soil, amorphous silica, Tripoli, powder, quartz). A SiO2 ore containing pure natural particulate silica powder. No brittle plasticity, the powder is not hydrophilic, strong acid resistance, differential thermal analysis of typical quartz the differential thermal curve, refractoriness 1750 ~ 1832 degrees. For ceramics, porcelain, glazed tile, fine ceramics, glass, paint, rubber filler and refractory materials, and can be used as fine abrasive, polishing material and precision casting sand. Silica 98.87%, ferric oxide 0.04%, two aluminum oxide 0.67%. three

Q: Process characteristics 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. Whiteness meter is a measure of a 3800 - 7000 (i.e., 1 =0.1 nm) wavelength of light reflectivity of the device. 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: What kind of kaolin can burn glazed tiles?: Kaolin is a kind of mineral material of better purity. It is not necessary to fire glass tile and kaolin, because glazed tile belongs to coarse pottery, and the quality requirement of clay is not fine

Q: In the paint, paint, ink, imported washed kaolin can replace part of titanium dioxide?: Paint and paint can be partially replaced, but it can affect whiteness and covering ability. Too much addition will make paint / paint a plastic fluid.Ink can not be replaced, because it will affect the rheological properties of the ink (become plastic circulation, is not conducive to printing).

Q: Will surface treated kaolin be more insulated than untreated?: Kaolin is an insulating material. If it is to increase the insulation of kaolin products, quartz, feldspar, calcite or mica stone should be added. If glaze, the effect will certainly be better.

Q: The difference between clay and porcelain: Clay fired ware called pottery, porcelain clay porcelain ware is fired, this is the difference between the two.

Q: What kind of pottery does kaolin need?: General ceramics are made of kaolin, different ceramics are only prepared in different proportions of the ingredients page.

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.
