Q:What's the difference between Ye Lashi and kaolin?
The content of Si in Ye Lashi is much higher than that of Al. The amount of burning loss is relatively small, and the linear shrinkage is much smaller than that of kaolin. When adding to the raw material, the sintering process can promote sintering.
Q:The difference between kaolin and calcium carbonate
Small flake, tubular, laminated and kaolinite mineral kaolin is mainly composed of a cluster of less than 2 microns (kaolinite, dickite, nacrite, halloysite etc.), chemical formula and ideal for AL2O3-2SiO2-2H2O, the main mineral is kaolinite kaolinite and water, in addition to kaolinite cluster mineral, montmorillonite, and Ye Lashi, illite, quartz and feldspar and other associated minerals. The chemical composition of kaolin contains a large amount of AL2O3, SiO2 and a small amount of Fe2O3, TiO2, and trace amounts of K2O, Na2O, CaO and MgO.
Q:What are the difficulties in kaolin beneficiation?
Kaolin is too fine to be chosen, and mineral size is the difficulty of mineral processing
Q:What's the difference between kaolin and clay?
White pottery is made from kaolin. Now the international general kaolin scientific name --Kaolin, is the source of the eastern suburbs of Jingdezhen Gaoling village of Gaoling mountain.Kaolin plasticity, adhesion, certain drying strength, sintering and sintering whiteness and other special properties, make it become the main raw material of ceramic production; white, soft, high dispersion, adsorption and chemical process with excellent performance, which was widely used in papermaking industry. In addition, kaolin also is widely used in rubber, plastic, refractory material, petroleum refining industry, agriculture and national defense technology field. According to the purpose and need for processing, processing and purification, all of them can be used to produce activated clay.
Q:Kaolin calcining temperature
The relative density of 2.5-2.6, the main component is alumina and silicon oxide crystal material with different crystal water, chemical formula Al2O3? 2SiO2? 2H2O (crystal water to form hydroxyl groups on the surface of kaolin). The structure: Si (Al) - OH - Si - O - Al - and - Si (Al) O, the activity is on the surface modification of kaolin clay foundation. The pH value is generally about 4-5, acidic, and the crystal structure of the -OH based adsorption accelerant, thus delayed vulcanization effect.
Q:What is the difference between kaolin and rare earth, which is better to use as ceramic? What effect will it have?
Rare earth is not a soil, but a metal, unless the metal glaze is generally not used, because the cost, but also because it is burned in a higher demand for the atmosphere,
Q:What are the colors of kaolin ore?
Containing Fe2O3 was rose red, brown and yellow; containing Fe2+ was pale blue, pale green with pale brown MnO2;
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:Kaolin crusher refers to which crusher?
The industrial departments of different uses of kaolin has a specific size and fineness in order to meet the requirements, paper, plastic and rubber products and other industries have higher requirements on the fineness of kaolin Raymond mill, it is necessary to increase the fineness of kaolin, so as to improve the product quality.
Q:What is the role of kaolin in plastics? What's the role of kaolin in plastic formulations?
Paint calcined kaolin, whiteness is higher, at least greater than 90%, and some manufacturers will require more than 93%.
