Sepiolite is rich of magnesium fibrous silicate clay mineral, the mainly chemical composition is (Si) and the magnesium (Mg) composes for the silicon, often assumes compact massive, earthy or fibrous, generally assumes the white, the gray or slightly brings the light red, dark green and brown. The adsorption performance and the heat-stable performance are excellent, thermostable and the electric insulation performance is good, the shrinkage is low, it's not easy to crack, as well as anti-salinity higher special performance.
Physical property:
The ore assumes clayey, the pellet is very thin, the naked eye is very difficult to distinguish, the color many to be pessimistic, or be brown. The sepiolite content is 20 generally--40%, other impurities are the quartz, the talc, the calcite and so on. This kind of ore reserve is rich, the application is widespread. The color is changeable, white majority, but also has light yellow, is light gray, is dark green, is not transparent, feel agglutination, the volume is big, proportion 2-2.5, non-toxic, tasteless, harmless , incombustible, the highest heat resistant 1750 degrees, the water-absorptivity in 1.5 times which is self-possessed, the catalysis, the absorptive quality is good.
Chemical property:
The molecular formula is:
Mg (H2O) 8H2O
SiO2 52%--65%; MgO 15%--25%; Moisture content <10%; PH 8--8.5
Chemical composition and performance:
1.The sepiolite fabric may widely apply in professions and petroleum, chemical industry, building materials, friction material, drugs manufacture;
2. May also take the heat preservation coating, may also take each kind of chemical the padding, the catalyst;
3.May also take each kind of liquid the deflocculant, the thickening agent, the clarifying agent, the decolorant and the house sound-insulated heat preservation deodorizes the material;
4. Makes brake lining's environmental protection product.
Granularity:
May produce 320 item of below products, including 320 items, 200 items, 100 goal powder body and each granulated product. According to the customer need, provides the corresponding use the physical property. The staple may adjust in certain scope.
Apllication:
1.The sepiolite has the shrinkage to be low, the plasticity is good, bears the alkali easily to dissolve, adsorption performance strong and so on unique industry performance, in addition, but also has the adsorption, the decolorization, the thermally stable, the corrosion resistance, the anti-radiation and the heat insulation, characteristics and so on insulation, mainly use in the building being sound-insulated, thermal insulation material, coating.
2. The product also uses in making the petroleum drilling mud;
3. Widely uses in keeping warm heat insulation raw material;
4. The drugs manufacture industry; The manufacture acid resistance drugs may use in a medicine grain of outlook, can cause the medicine to bear the oxidation to draw back changes.
5. Can be used as the filter aid for the wines and the oil class, enhances the transparency, and reduces the precipitation.
7. Uses in the rubber industry.
8. It can be used in cigarette's filtration and adsorb the noxious gas.
9.Widely used in specially the non-asbestos friction packing material in the recent years.
According to the adjustment of the state administrative policy and the transformation of the automobile friction materials to non-asbestos, our factory introduce advanced technology from Germany and specialized automatic production line of fiber products. The fiber products we manufactured are ideal material which can replace asbestos in friction materials. We have mineral fiber, ceramic fiber, nature cellulose fiber, composite fiber and so on. Brake linings made from our fiber products have many notable features such as braking stably, high temperature properties, little abrasion, low (no)noise and long life. They are very popular in friction materials manufacturers.
