the north mining plant

We are the north mining plant based in Shijiazhuang , China. We are member of exporthub.com since January, 2011. Our business is related to Minerals & Metallurgy industry and we specifically deal in Nonmetallic minerals. Please find our product details below:veimiculiteVermiculiteOur factory professionally produces insulation refractory material special vermiculite, main types are: 1-2-3mm, 4mm, 10-20 mesh, 20-40 eye, 40-60 item, 80-120 mesh, etc.Vermiculite series: Golden vermiculite, silvery white vermiculite, intercalated flake, etcVermiculite explainVermiculite is a layered structure containing magnesium silicate secondary metamorphic minerals water aluminum ore outside, like mica, usually by black (golden) mica by hydrothermal altered effects or weathering and become, because its heated dehydrate expands is flexing shape, form resembles leeches, therefore calls vermiculite.Vermiculite of patent for (Mg, Ca) 0.7 (Mg, Fe, Al [(Al) 6.0, Si) 8.0] (OH4.8 H2O)Vermiculite by phases is divided into ShiYuan intercalated ore deposits and expanded vermiculite, color-coded classification can be divided into golden vermiculite, silvery white vermiculite. Ivory vermiculite.I plant production configurations of high-temperature roasting ShiYuan ore can rapidly expanding its volume 8-20 times, expand the proportion of 130 - after 180kg/m3. In fire prevention insulation good thermal insulating properties.Intercalated quarries silvery white vermiculite golden vermiculiteVermiculite chemical compositionComposition SiO2 Al2O3 MGO style Fe2O3 CaO pH H2OContent (37-42 %) 9-17, 11-23 5-18 0.5-0.8 8-11 < 1Main specifications and technical indexesIntercalated ShiYuan ore:Specifications 2 slices 3 piece 4 piece 5 piecesSize (mm) 5-7 3-5 1-3 < 1Expanded vermiculite:Level loose proportion (kg/m3) water imbibition (%) impurities (kg/m3)1 130 480 < 12 160 450 < 13 180 420 < 1Sell Environmental food water treatment maifan stone liao maifan stoneMaifan stone is a kind of biological avirulent, harmless and have certain bioactive compound mineral or medicinal rock. Maifan stone for the parent rocks often, acidic magmatic rocks. The chemical constituents of Ca, Mg, divide common, Si, Al, Fe, K, making outside, still have a few rare elements and rare earth elements, radioactive elements. Maifan stone has adsorption, dissolving, PH accommodative, biological activity and mineralization resistance. It can absorb water free of metal ions. Maifan stone containing Al 2 O 3 about 15% is typical of both sexes oxides, in aqueous solution meet alkali reacts lower PH value, encounter acid reacts improve PH value, has the function of two-way adjusting PH of maifan stone by blisters j, can dissolve out to human body and biology useful major elements K, Ca, Mg, making, P and Si Fe, Zn, Cu, Mo, and Se, Mn, Sr, Ni, V, Co, Li, Cr, I, Ge, Ti trace elements. Maifan stone in aqueous solution can also let the human must the amino acids.Maifan stone widely healthcare, food, beverage and water purification, sewage treatment, anti-corrosion, deodorant, preservation, decontamination, porcelain making and planting and breeding industry, etc.Common specification: 0.25-0.5 mm. J, 0.5-1.0 mm, 1.0-2.0 mm, 2.0-4.0 mm, 4.0-8.0 mm, and 8.0-16mmChemical compositionMain ingredients SiO2AL2O3Fe2O3K2ONa2CaOMgO stylecontent68.2415.343.044.124.122260.89Maifan stoneJoint venture, after crushing points sieve maifan stone into below specification: 0.25-0.5 mm, 0.6-1.2 mm, 1-2-2mm, 4mm, 4-8-16mmmm 8mm, such as specifications.The product has the following features:(a) biological activity: maifan stone water called active water has obvious biological effect, for in yeast and baking industry use maifan stone improve product output and quality provides a broad prospect of application.(2) of water adsorption: maifan stone is heavy metal ions Pb, employed by Hg, Cr, Cd, As organic matter, germs toxic or harmful substances, such As, has the strong adsorption effect. For Pb, employed by Hg, Cr, Cd, As adsorption rate above 96% of e. coli adsorption rate of 95%. It can absorb and decompose the liquor methanol in and fusel oil to improve its quality. In addition, still can make anticorrosive, preservation, deodorant materials.(3) mineralization sex: will maifan stone submerged, water will ore into approximate mineral water of KuangHuaShui, one of the minerals and trace elements are necessary to the human body.(4) water quality adjustment sexual: maifan stone has two-way adjusting PH value function, can make the acidic or alkaline water regulation show neuter, make water alcoholize, activeness, sweet taste good.Product technical indexesAnalysis of projectdensitybulkstrengthWear rateBreaking ratesilicaTest data2.55 g/cm31.7 g/cm3> 97 percent0.39 per cent0.41%68.4%Analysis of projectFe2O3Iron oxideAl2O3Manganese oxidemagnesiumsodiumTest data1.29%3.40%9.6%0.02%3.55%3.16%Analysis of projectkAdsorption watercaotitaniumIntegrating withAnhydrous phosphorusTest data3.19%1.10%2.00%0.30%animals0.26%Both maifan stone applications: also are suitable for eco clothing environmental protection products: functional fibers are with the cotton and wood extracted cellulose, this kind of cellulose fiber, therefore, this belongs to the natural maifan stone functional fiber also belong to pure-fiber. In this fiber woven fabric, its performance than cotton fabrics and other chemical class fiber fabric wearing more comfortable, no static, hygroscopicity strong, good air permeability, dyeing bright-coloured, rich velvet sense of style. Can be used to make various male, the female underwear, especially vest shorts, health care effect is better. Still can make sheet, shirt, pillowcase, socks, or with pure cotton, mix knitted fabric, this make various knitting maifan stone functional fibers are contemporary developing high-tech health textiles ideal material.1, to the body trace element supplement. Because of maifan stone on functional fiber contain large variety of essential trace elements, these trace elements can be used as a body for the trace elements, forming storage trace element source, seasonable compensatory human body needs zinc, selenium, calcium and other trace elements, and regulating body balance. Maifan stone elements on functional fiber through direct contact with the skin, the wool stoma permeate in body, absorbing the surrounding environment and human itself of radiant energy, make the blood is accelerated circularly, blood capillary dilate, strengthens the micro circulation, thus improving the self-discipline movement microcirculation, promoting the normal metabolism level and physiological function, at any time to exclude microcirculation impeded various diseases.2, good adsorptive function. Because maifan stone functional fiber has good adsorptive function, when maifan stone function fiber fabric in contact with the skin, the human body harmful peroxide garbage (fiber mud) has a strong adsorption function, in order to promote the wool stoma within peroxide garbage excretion, lose tong capillary, make the capillary maintain normal metabolism level and physiological function, rise to prevent and treat various skin diseases heavyThank you for taking the time to go through our business profile.
