CALCINED KAOLIN FOR CERAMICS (GB-CK80) Best Quality

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:What's the requirement of high-grade kaolin?: Whiteness is one of the main parameters of kaolin's technological properties. Kaolin with high purity is white. Kaolin whiteness, natural whiteness, and degree of self calcination. For ceramic raw materials, the whiteness after burning is more important. The higher the calcination whiteness, 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 light at 3800 7000A wavelengths. In the whiteness meter, the reflectance of the sample to be measured is compared with that of the standard sample, that is, the self - value.

Q:Is it near the clay ore: Magnetite and hematite deposit in native rock, mica, feldspar is there very little, it is difficult to become China clay resourcesOnly the limonite is weathering secondary ore, mica, feldspar will resident may be near, the clay;

Q:What kind of soil can be used as a ceramic?: Clay - clay, refers to contain iron with brown, gray, red purple color, with good plasticity of clay. The mineral composition in the clay, montmorillonite, kaolin.

Q:Can calcined kaolin be used in PVC tubing?: At present, calcined kaolin has been widely used in ceramics, rubber, plastics, artificial leather, cement, refractory materials, chemical industry and agriculture.

Q:Kaolin, calcium carbonate, talc, which does not affect the ink gloss?: Kaolin, calcium carbonate and talc powder as a kind of inorganic filler will affect the ink gloss, the most important influence is reflected in the kaolin, calcium carbonate and talc powder in water content, too much water, the influence of ink concentration, which will affect the use of ink printing effect, so the detection of moisture content it is necessary to.

Q:Should kaolin be used in polyester production?: But in the process of polyester production, the ordinary polyester fiber can be modified by adding kaolin particles in the spinning solution, thus improving the properties of polyester fiber.

Q:Can pure kaolin or montmorillonite burn pottery? If not, what do you need to add?: More than two of the hard nature of the poor, so the use of ceramics in relatively small, mainly chemical raw materials. However, because of the scarcity of soft soil and higher prices, many manufacturers have been studying the hard kaolin and other viscous ores to achieve the above results. That is, it can reduce the cost and produce better ceramics.

Q:How can we tell if there's kaolin in that hill?: Having plasticity; wet soil can be molded into various shapes without breaking, and can remain unchanged for a long time.Specific or to pass the test. If you need to test, you can contact me, we analyzed the testing center, the phone is the user name.

Q:What are the differences between kaolin and kaolin? What are the chemical constituents?: (kaolin) also called Gaoling reservoir soil, white clay, clay soil, Yang (porelain clay). The main component is aluminum silicate hydrate (A12O3.2SiO2.2H2O). The color white or grayish, a hexagonal flaky crystal, the relative density is 2.54 ~ 2.60, oil content is 30% ~ 50%. kaolin pH value is generally 4 ~ 5. A weak acid.
