One kind richly including the magnesium fibrous silicate clay
mineral, the chemical composition mainly (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 sense
of touch smooth, sticks the tongue, the quality of material to
be light, the dryness can float in the water surface, is wet
when soft, plastic. And has in a big way compared to the
surface area, the adsorption performance, the heat-stable
performance are high, thermostable, the electric insulation
performance is good, the shrinkage is low, is not easy to
crack, as well as anti-salinity higher special performance.
1. 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, be brown. The sepiolite content is *0
generally***0%, 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 **2.5, non-toxic, does not have the unusual
smell, does not have the environmental damage, incombustible,
the highest heat resistant ***0 degrees, the water-absorptivity
in 1.5 times which is self-possessed, the catalysis, the
absorptive quality is big good.
2. Chemical property:
The molecular formula is: Mg (H2O) 8H2O
Product content: SiO2 *2%***5%; MgO *5%***5%; Moisture content
<*0%; PH ***8.5
3. Chemical composition and performance:
The sepiolite fabric may widely apply in professions and so on
petroleum, chemical industry, building materials, friction
material, drugs manufacture; May also take the heat
preservation coating, may also take each kind of chemical the
padding, the catalyst; 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; Makes brake lining's environmental
protection product.
4. Granularity:
May produce **0 item of below products, including **0 items,
**0 items, **0 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.
5. Sepiolite use:
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.
1. mainly use in the building being sound-insulated, thermal
insulation material,keeping warm heat insulation raw material
and coating.
2. The product also uses in making the petroleum drilling mud;
3. The drugs manufacture industry may use it aslo ,manufacture
of acid resistance drugs may use in a medicine grain of
outlook, can cause the medicine to bear the oxidation to draw
back changes.
4. May make the filter aid to use in the wines and the oil
class, enhances the transparency, reduces is mixing and the
precipitation.
5. Uses in the rubber industry, causes the rubber the modulus,
the anti-bulge intensity, degree of hardness, the resistance to
wear, anti-rip the strength to advance, the time may improve
the aged performance, the alleviation degree of aging.
6. May use in the paraffin wax, the petroleum, the vegetable
oil decolorization. With makes cigarette's filtration ju, may
first adsorb the noxious gas.
7. Widely used in specially the non-asbestos friction packing
material in the recent years.
