Description

The application of serpentine in the preparation compound
Technical field
The present invention relates to the comprehensive utilization field of ore, be specifically related to the application of serpentine in the preparation compound.
Background technology
Serpentine is a kind of hydrosilicate mineral of magnesium.Generally have mottled decorative pattern, particularly its polished face is gained the name the spitting image of snakeskin thus.
The chemical constitution of serpentine is 3MgO2SiO 22H 2O or MgO [Si 4O 10] (OH) 8, wherein contain Natural manganese dioxide (MgO) 43.0%, silicon-dioxide (SiO 2) 44.1%, water (H 2O) 12.9%.Common tramp material has red stone (FeO), red oxide of iron (Fe 2O 3) and nickel oxide (NiO).
The serpentine kind is a lot, and common have common serpentine, noble serpentine, resinous serpentine, sea bubble serpentine, bowenite, lobate serpentine, a marmolite etc.The common feature of this type mineral is that their chemical combination very easily tends to form colloidalmaterial, or phanerocrystalline-adiagnostic scale aggregate, and is phaneritric few.
Because kind is different, serpentine is depth distinct colors, like dark green, blackish green, yellowish green, light red, pale green, brown Huang, white etc., and the striped that all has color of the same race.Generally has oily luster or cured shape gloss.Fusibility 5-5.5.Has the hardness between the Mohs' hardness 2.5-4; Wherein common serpentine is 2.5-3, and antigorite is 3.5.Proportion 2.5-2.8.Hand has touched sliding sense, and fracture is a conchoidal.The peelable slabbing of antigorite.
Serpentine is a kind of secondary mineral, is to receive by being rich in magnesia rock that large-scale hydrothermalism generation chemical reaction is rotten to form.There are two kinds of origin causes of formation in the mineral deposit: a kind of is by one type of ultrabasic rocks stones such as primary peridotites, pyroxenolites, receives the metasomatosis of the hydrothermal solution of volcanic rock (like grouan) intrusive body, and peridotites changes serpentine into.
3Mg 2SiO 4+4H 2O+SiO 2→Mg 6[SiO 4O 10](OH) 8
Or 2Mg 2SiO 4+ 2H 2O+CO 2→ H 4Mg 3Si 2O 8+ MgCO 3
Another kind is the hydrothermal solution of volcanic rock intrusive body, to being rich in magnesia scud or scud fossil limestone is handed over reaction, generates serpentine:
6CaMg[CO 3] 2+4H 2O+4SiO 2→Mg 6[Si 4O 10](OH) 8+6CaCO 3+6CO 2
Become in the mineralising reaction at above-mentioned two kinds, peridotites, scud are primary rock mass, and water, silicon-dioxide and carbonic acid gas are all relevant with the volcanic rock intrusive body.In the hydrothermal solution of volcanic rock intrusive body; Often contain a large amount of silicon-dioxide and carbonic acid gas; When hydrothermal solution flows along peridotites or dolomitic crack, meet suitable chemical reaction condition and place chemical reaction just takes place, formation serpentine or fibrous chrysotile.
In sum, no matter give birth to the serpentine mineral deposit in peridotites, still giving birth to the serpentine mineral deposit in scud or scud fossil limestone, all is owing to formed by the metasomatism of the hydrothermal solution of volcanic rock.And the scale in preceding a kind of mineral deposit is generally bigger, though then one type of distribution is wider, scale is generally less.
Serpentine has good thermal property, chemicalstability and adsorptivity etc., and the performance of chrysotile is more excellent.
(1) physical strength.Except that the tensile strength of spun glass and boron fibre was close with chrystile, the tensile strength of all the other common fiber materials was all not as good as chrystile (about 2600-3100MPa).
(2) thermostability.The structure deteriorate of chrystile is about 650-700 ℃.The heat absorption paddy temperature of rich magnesium chrystile is about 700 ℃.Chrystile is at obvious deshydroxy more than 500 ℃, and structure begins to destroy.The thermal conductivity of chrystile is less than 0.233W/ (mk).
(3) electrical properties.Chrystile belongs to semi-insulator, is good heat-resistant insulation material, and the thermal isolation life-span is very long.The chrystile mass resistivity is 104-108 Ω g/cm 2, be superior to amphibole asbestos (104-107 Ω g/cm slightly 2).
(4) chemicalstability.The chrystile alkali resistance is strong, and acid resistance is poor, mainly is that " brucite " layer is damaged.Continue to carry out with acid corrosion action, its MgO obviously reduces, SiO 2Content increases, and gradually becomes the silica gel of tool fiber illusion.
(5) absorption property.The adsorptivity of chrystile is relevant with the key property of its specific surface area and fiber surface.The double-deck dipole that different valency ion substitution is produced makes chrysotile asbestos fibre to polar water molecules very strong adsorptive power arranged.
