Calcined Kaolin Particles White 20mesh Kaolin¹

Product Description Calcined Kaolin Particles White  20mesh KaolinProduct DescriptionKaolin is a kind of kaolinite mineral clay and clay rock that has good plasticity and fire resistance.Kaolin application mainly used for paper making,ceramics,refractory materials, secondly used in paints, rubber filler, enamel glaze and white cement raw material, some used in plastics, paint, paint, grinding wheel,pencil, daily cosmetics,soap, pesticidemedicine, textile, oil, chemical industry,building materials, and so on.Kaolin is divided into: washed kaolin, calcined kaolin, lightweight kaolinKaolin is a mixture of inorganic nonmetal, calcined kaolin is calcined kaolin in sintering furnace to a certain temperature and time, the physical and chemical properties which has a certain change, in order to meet certain requirements.The main specification: 200mesh 325mesh 400mesh 600mesh 800mesh 1250mesh 3000mesh 4000mesh etcThe difference of Calcined Kaolin with Washed KaolinFirstly, calcination of kaolin involves chemical changes in its crystal structure and original soil during calcination, while washing kaolin with water only results in physical changes and does not alter the properties of the original soil;Secondly, the whiteness of calcined kaolin is relatively high, while the whiteness of washed kaolin does not significantly increase, resulting in a significant difference;The third type of calcined kaolin mainly refers to hard kaolin. The original soil has no cohesiveness and cannot be directly used as a raw material for papermaking or refractory materials. It needs to be calcined and used. However, the original soil of washed kaolin has cohesiveness and can be directly used as a binder for refractory materials or paper fillers. In general, Baidu is better for calcining kaolin and can be used in the papermaking industry, but the corresponding cost is also relatively high.SpecificationMelting point1750 °Cdensity2,6 g/cm3refractive index1.6200storage temp.no restrictions.LogP-0.434 (est)The sample of the goodsCalcined Kaolin 4000meshAppearanceWhite PowderAl2O344±2SiO251±2Fe2O3≤0.5Whiteness≥93Particle Size (-45um%)≥83325 Mesh Residue (45um) %≤0.003Oil Absorption (g/100g)55-65Moisture %≤0.5Dispersibility (um)≤55Refractive Index1.62PH6.0-8.0 The sample of the goodsWashed KaolinLOSS13.88Al2O338.40SiO246.17Fe2O30.82CaO<0.01MgO<0.01K2O0.43Na2O<0.01TiO20.14 ≤55Refractive Index1.62PH6.0-8.0 Detailed PhotosPropertiesSpec.Test results for referenceRefractoriness, oC≥1790 1790Bulk Density, g/cm3≥2.48 2.48L.O.I (%)≤0.25 0.20Mullite Phase (%)55-65 58Mohs Hardness2-3 3Fines in sands,%≤0.30.01PH Value6-8 6.5Al2O3,%46-4846.62SiO2,%50-5250.81Fe2O3.%≤1.20.89TiO2,%≤0.70.60CaO+MgO  %≤0.50.38K2O+Na2O,%≤0.50.38Size Available10-16mesh, 16-30mesh,30-60mesh, 200mesh,270mesh,325mesh800 mesh,1250 mesh,2000mesh,4000 mesh Or follow customers' requirement   Applications1) Paper- making Industry: It is mainly applied in the coating paper, art paper, white board paper, corrugated paper, coatingwhite board paper; Cast coated paper and so on . It is more applicable in gravure printing for its good loose depth and elasticity which can guarantee less leaks and spots.2) Coating Industry : Its whiteness, smoothness and non- transparency can be well improved by adding Kaolin to the pigment in the process of coating paper and paper board.3) Oil and Paint Industry :It can well improve the viscosity, fluidity, anti-precipitation and so on. The enamel glaze slip'properties of floatation, viscosity, adherence and thermal casting resistance can be well improved by adding Kaolin because it can make the cast enamel more adhesive to iron billet. Kaolin also plays the role of anti-precipitating when used in water paint. It is also a kind of good inorganic latex agent.4) Rubber Industry : In the production of cable rubber and plastics, kaolin can improve the abrasiveness, hardness, anti-shock and extension rate.5) Plastic Industry : It plays the role of reinforcement with its good dispersion. It also can stop the infrared rays of wavelength from 7-14um in thick film so as to increase the temperature in the shed.6) Ceramics : It is widely used in high and low voltage ceramic, all kinds of ceramic billet and enamel; It is also applied in all kings of refractory.7) Cable Industry : It can greatly improve the specific volume resistance, dielectric strength, retardant effectiveness with its good dispersion and reinforcement. Packaging & Shipping FAQ1. who are we?We are based in Hebei, China, start from 2020 sell to Southeast Asia,North America,South America,Oceania,Mid East,Eastern Asia,Western Europe,Northern Europe,Southern Europe. 2. how can we guarantee quality?Always a pre-production sample before mass production;Always final Inspection before shipment;3.what can you buy from us?Vermiculite,Mica powder,Colored Flakes,Talc Powder,,Horticultural Products4. why should you buy from us not from other suppliers?Hebei Yingrui is Hebei province's comprehensive industry and trade intergration of the most powerful one of the non-metallic mineral enterprises,we have our factory and cooperate factory5. what services can we provide?Accepted Delivery Terms: FOB,CFR,CIF,EXW,Express DeliveryAccepted Payment Currency:USD,EUR,JPY,CAD,AUD,HKD,GBP,CNY,CHF;Accepted Payment Type: T/T,L/C,MoneyGram,Western Union,Cash;Language Spoken:English,Chinese
