ACTIVE ALUMINA SILICATE IN RUBBER (GB-CKR901)

Q: Do kaolin have blue and cyan?: Kaolin is mainly aluminosilicate, the main component of AL2 (Si2O5) (OH) 4, or written as Al2O3 2H2O 2SiO2

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: What is the best composition of kaolin?: Kaolin is mainly aluminosilicate, the main component of AL2 (Si2O5) (OH) 4, or written as Al2O3 2H2O 2SiO2

Q: How to remove iron impurities in kaolin and increase their whiteness: The types of pigment ions are different, and the reagents and methods used are different:1, the surface of the adsorbed kaolinite is Fe3+, that is, when iron exists in the form of Fe2O3, the reaction of Fe3+ with Na2S2O4 is reduced to two valent iron salt, which is removed by rinsing and filtering;2, when the adsorption ion is Fe2+, that is iron in the form of FeS2, the oxidant should be used and its reaction, the oxidation of soluble ferrous sulfate and ferric sulfate, so that it can be washed away colorless oxides;3, the majority of samples containing both Fe3+ and Fe2+, the oxidation reduction combined bleaching method, first with the oxidant and reducing agent will become Fe2+ Fe3+ its reduction to Fe2+. Removed by rinsing, filtering, etc.

Q: Application of kaolin: Kaolin has become the mineral material necessary for papermaking, ceramics, rubber, chemicals, coatings, pharmaceuticals and national defense.Ceramic industry is the earliest and larger amount of kaolin. The general dosage is 20% to 30% of the formula. The role of kaolin in the ceramic is conducive to the introduction of Al2O3, mullite, the chemical stability and sintering strength during sintering kaolin decomposition of mullite, the main frame form body strength, can prevent the deformation of the product, the firing temperature becomes wide, can make the body with whiteness some. At the same time, kaolin has a certain degree of plasticity, adhesion, suspension and binding capacity, given the enamel porcelain clay, good formability, the ceramic clay for car billet and grouting, easy forming. If used in an electric wire, insulation can be increased and dielectric loss is reduced.

Q: I only know that is a kind of raw material, and sell them where to sell, and I can have to contact the white mud!: There are reports that Japan has also used kaolin instead of steel, cutting tools, lathes, drills, and internal combustion engines. Especially in recent years, the rapid development of modern science and technology, the application of kaolin is more extensive, began extensive use of kaolin as new materials in some high-tech fields, and even nuclear reactor space aircraft and spacecraft components with high temperature porcelain, made of kaolin.

Q: The building is kaolin. Does it have radiation? District 15 years ago is a kaolin processing plant, there will be residual radiation it?: The first thing to stress is that the world is full of radiation, whether it's land, sea, mountains, fields, rocks, soil...... We call it the background radiation intensity".

Q: China clay, kaolin clay, three what is the difference? Is China clay is kaolin chemical elements of the three specific? What is the difference?: Clay: the composition is complex, mainly composed of kaolinite, water mica, montmorillonite, quartz and feldspar, mainly montmorillonite and kaolin. It is only used in pottery manufacture

Q: What are the requirements for the whiteness of calcined kaolin in the coating formula?: Whiteness stability is very important, if the Baidu volatility assembly affects the optical properties of the coating, resulting in the same batch of products obvious color difference.

Q: Hard kaolin in the ceramic piece, which is used in which? What's the difference between washed 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.
