- Q:What's the difference between calcined kaolin and washed kaolin?
- First of all, calcined kaolin is calcined, crystalline and raw soil has changed; and washed kaolin is only physical treatment, will not change the properties of raw soil
- Q:How do porcelain mud distinguish good or bad?
- The difference between the mines leads to uneven composition and leads to inconsistent quality. The loss of many mud and glazes in China is very important for this reason.
- Q:What is the difference between kaolin and rare earth, which is better to use as ceramic? What effect will it have?
- Kaolin is a representative of clay, commonly used in glazes, which can increase whiteness and provide suspension and adhesion
- Q:What is the porcelain glaze porcelain
- The clay is composed of metamorphic mica and feldspar, in which sodium and potassium, calcium and iron loss, water changes into. The glaze is covered in colorless or colored ceramic surface of the glass layer is raw minerals (quartz, feldspar, talc, kaolin etc.) and chemical raw materials according to a certain proportion (part of raw material can be made by grinding glaze frit), applied to the blank surface, under certain temperature and calcining.
- Q:What is the significance of the target in kaolin?
- At present, it is more popular to calculate the diameter of equivalent volume particles by particle size, in units of M or mm.
- Q:Kaolin, calcination and washing what is the difference between the best, you can talk about it in detail,
- Washing is the sand in the raw ore and impurities through the role of panning purification, usually three of the original ore oxidation, two aluminum content is very low, about 17-25%, if the amount of aluminum is too low, can not wash out the purity of kaolin, it is not worth washing
- Q:High silica can be converted into kaolin? Add or remove some of the substances, specific operations! Thank you
- High silica containing SiO2 pure natural particulate quartz powder. It is brittle, without plasticity, powder is not hydrophilic, acid resistance is strong, differential thermal analysis has typical quartz differential thermal curve, the refractoriness is 1750~1832 degrees.. More than 90% silicon dioxide, a small amount of ferric oxide, three small two aluminum oxide.
- Q:Process characteristics of kaolin
- Non plasticity <1 viscosity is a characteristic of a fluid that hinders its relative flow due to internal friction. Its viscosity is used to indicate its size (the internal friction force applied to 1 units per unit area). The unit is Pa. S. Viscosity measurements are generally made using rotational viscometer to measure the rotational speed in kaolin slurries containing 70% solids. Viscosity is very important in the process of production. It is not only an important parameter of ceramic industry, but also a great influence on the paper industry. According to data, foreign kaolin as paint, coating at low speed requires viscosity of about 0.5Pa - s, high-speed coating requirements of less than 1.5Pa - S.Thixotropy refers to the characteristics of a fluid that has become gelatinous and no longer flowing. It becomes fluid after stress and gradually becomes intact after being stationary. The size is expressed by a thickening factor and measured by an outflow viscometer and a capillary viscometer.Viscosity and thixotropy are related to the mineral composition, particle size and cation type in the mud. In general, the content of montmorillonite is fine, the particles are fine, and the exchangeable cations are mainly sodium, with high viscosity and high coefficient of change. Therefore, it is often used to increase the viscosity and thixotropy of plastic clay, improve the fineness and so on, and reduce it by increasing dilution, electrolyte and water content. The drying performance of kaolin clay material in the drying process. Including drying shrinkage, drying intensity and drying sensitivity.
- 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:Kaolin calcining temperature
- Clay can be divided into hard clay (hard clay) and soft clay (soft clay). The hard clay particles with smaller particle size, below 2 m accounted for 87-92%, its good reinforcing effect, soft clay, coarse particle size below 2 m accounted for 50%, more than 5 m about 25-30%, the reinforcing.Hard clay and not only for the poor classification on the mineralogy, the rubber with have different differences, especially the influence on the synthesis of the more obvious natural rubber.
