Q:How to remove iron impurities in kaolin and increase their whiteness
The two stage bio bleaching method refers to: firstly, Aspergillus niger in shake flask cultivation fermentation, 10 days or so, organic acids accumulated to a certain amount, then separate, the addition of kaolin can also achieve iron removal and whitening effect. The two stage biological bleaching method not only overcomes the above-mentioned shortcomings of in-situ biological bleaching, but also achieves the highest concentration of organic acids (especially oxalic acid) at suitable pH.
Q:What is the solid content in kaolin index?
Refers to the content of kaolin will not be issued, the method of detection is not very clear.
Q:How to improve the viscosity of kaolin
Medium stone Hengda teaches you how to improve the viscosity of the product: adding plastic clay to improve fineness, so as to improve the viscosity and thixotropy of the product.
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:How are laterite and kaolin weathering crusts formed respectively?
Humidity is relatively large, precipitation is relatively large environment, easy to do so, mainly in the equator and nearby areasThe area is high humidity, precipitation, and so the soil organic matter and +1, -1 ions, as well as easy to drain ingredients are leached by water, bring out the ecosystem, and the rest are mainly strong oxidation of iron, magnesium and other oxides
Q:Which mixer can be more evenly dispersed kaolin slurry?
If you love to drink fruit juice drinks of all kinds, so it is recommended to select with mixer speed regulation, so that you can freely adjust the stirring speed, some fruit juice does not need to stir too broken to drink. Therefore, you can choose a mixer with speed control function.
Q:The difference between bauxite, kaolin and clay
The quality standard of kaolin is mainly composed of small, flaky, tubular and laminated kaolinite minerals less than 2 microns. Kaolinite minerals: cluster by kaolinite, dickite, nacrite, halloysite etc., chemical formula and ideal for AL2O3-2SiO2-2H2O, the main mineral is kaolinite kaolinite and kaolinite mineral water, in addition to the cluster, and montmorillonite, illite, quartz and feldspar, Ye Lashi and other associated minerals. Kaolin plasticity, adhesion, certain drying strength, sintering and sintering whiteness and other special properties, make it become the main raw materials Kaolin ceramic ceramic production, is a mainly composed of kaolin clay. The name was first found in kaolin village, northeast of Jiangxi, Jingdezhen province.
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:What are the colors of kaolin ore?
Contains the quality is pale yellow, gray, green, black and other colors. The presence of these impurities, reduced the natural whiteness of kaolin, in which iron and titanium minerals will also affect the whiteness of the calcined, porcelain stains or scars appear.
Q:Can kaolin be used for cosmetics?
Kaolin is mainly composed of two oxygen silicon and three aluminum oxide two. Do high-end cosmetics, kaolin requirements of pure white, fine granularity (1250 mesh).
We make good use of kaolin resources when exploring the coal fields. In conclusion, we can cut down the cost of resources by 80%. Meanwhile the effective of resources usage can be increased by 200%. Our company will improve the linkage of production and circulation. Faithful team, excellent style of work, fortitude nature, professional goods and delicate service will provide our customers with the finest cooperative atmosphere to achieve a win-win result.
