325目铝矾土 铝矾土粉末 出口韩国

      铝矾土又称矾土或铝土矿，主要成分是氧化铝，系含有杂质的水合氧化铝，是一种土状矿物，白色或灰白色，因含铁而呈褐黄或浅红色。密度2.4-2.5g/cm3，硬度1～3，不透明，质脆，极难熔化，不溶于水，能溶于****溶液，主要用于炼铝，制耐火材料。 

      熟料为灰白浅黄及深灰色，它主要用于高铝质耐火材料，也可用来制作电熔棕刚玉。高铝矾土熟料是按AL2O3含量及Fe2O3、TiO2、CaO+MgO、K2O+Na2O等杂质含量和熟料体积密度与吸水等项指标来分级的。

      轻烧铝矾土，又称轻烧粉，是净水剂聚合氯化铝的原材料，是铝矾土经过加工生产出来的矿粉材料，主要成分是氧化铝，系含有杂质的水合氧化铝，是一种土状矿物。白色或灰白色，因含铁而呈褐黄或浅红色。密度3.9～4g/cm3，硬度1～3，不透明，质脆。极难熔化。不溶于水，能溶于****溶液。

      (1)生矾土，即矾土原矿石(天然沉积岩类)。

      (2)熟矾土，将生矾土经高温煅烧后(1200～1700℃)称为熟矾土。

      高铝矾土熟料是按AL2O3含量及Fe2O3、TiO2、CaO+ MgO、K2O+Na2O等杂质含量和熟料体积密度与吸水等项指标来分级的。

      1、炼铝工业。用于国防、航空、汽车、电器、化工、日常生活用品等。  

      2、精密铸造。矾土熟料加工成细粉做成铸模后精铸。用于军工、航天、通讯、仪表、机械及医疗器械部门。 

      3、用于耐火制品。高铝矾土熟料耐火度高达1780℃，化学稳定性强、物理性能良好。 

      4、硅酸铝耐火纤维。具有重量轻，耐高温，热稳定性好，导热率低，热容小和耐机械震动等优点。用于钢铁、有色冶金、电子、石油、化工、宇航、原子能、国防等多种工业。它是把高铝熟料放进融化温度约为2000～2200℃的高温电弧炉中，经高温熔化、高压高速空气或蒸汽喷吹、冷却**成了洁白的“棉花”——硅酸铝耐火纤维。它可压成纤维毯、板或织成布代替冶炼、化工、玻璃等工业高温窑炉内衬的耐火砖。消防人员可用耐火纤维布做成衣服。 

      5、以镁砂和矾土熟料为原料，加入适当结合剂，用于浇注盛钢桶整体桶衬效果甚佳。 

      6、制造矾土水泥，研磨材料，陶瓷工业以及化学工业可制铝的各种化合物。

Bauxite also known as alumina and bauxite, main component is aluminum oxide, hydrated alumina containing impurities, is a kind of earthy mineral, white or grey, due to iron is brown yellow or light red. Density 2.4-2.5g/cm3, hardness of 3 ~ 1, opaque, brittle, very difficult to melt, insoluble in water, soluble in sulfuric acid, sodium hydroxide solution, mainly used in aluminum, refractory materials.
1, aluminum smelting industry. Used in national defense, aviation, automotive, electrical, chemical, daily necessities, etc..
2, precision casting. Bauxite is processed into fine powder and made into mold. Used in military, aerospace, communications, instrumentation, machinery and medical equipment sector.
3, used for refractory products. High bauxite clinker high refractoriness of up to 1780 DEG C, strong chemical stability, good physical properties.
4, aluminum silicate refractory fiber. Has the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, has the advantages of small heat capacity and resistance to mechanical vibration etc.. For steel, nonferrous metallurgy, electronics, petroleum, chemical, aerospace, atomic energy, defense and other industries. It is the high alumina clinker into the melting temperature of about 2000 ~ 2200 degrees of high temperature in the electric arc furnace, the high temperature melting, high pressure air or steam injection, cooling, became a white "cotton" - aluminum silicate refractory fiber. It can be pressed into a fiber blanket, plate or woven into cloth instead of smelting, chemical, glass and other industrial furnace lining refractory brick. Fire fighters can be made of refractory fiber cloth clothes.
In 5, magnesia and bauxite as raw material, adding appropriate binder, used for pouring ladle lining the whole barrel effect.
6, made of alumina cement, abrasive materials, ceramic industry and chemical industry can be a variety of aluminum compounds.
