Mica:
My factory production mica
product includes: The mica is garrulous, mica powder. White mica productivity
sufficient, the craft is mature, the main model includes: 10-20 item, 20-40
item, 40-80 item, 80-120 item, 200 item, 325 item and so
on.
The mica mainly crystallizes the clinorhombic system,
the crystal assumes the vacation six sides thin laminated shapes, scaled,
plate-type, sometimes assumes the vacation shape. Degree of hardness 2-3,
proportion 2.70-3.20.
The mica refractive index advances along
with the hard content but correspondingly advances, may by be low is breaking
out to the center is breaking out. Does not contain hard the variety, in the
thin slice the achromatic color, when contains the iron high, the color is
deeper, simultaneously polychromous and absorptive
enhancement.
Within the boundaries of Lingshou County the
stratum for the antique double nature rock layer, in the rock layer is
containing the rich mica mineral, explores after the quality of material
department, the garrulous mica reserves amounts to 1.7 million tons, the grade
of ore high, the quality is good, is the national only garrulous mica habitat.
The mica powder has uniquely is acidproof, bears study the stability, has the
thermal stability, but also has the good insulating property. In
international, the domestic market the use is day by day widespread. May apply
to the building materials profession replaces the asbestos product.
| Ingredient | SiO2 | Al2O3 | Fe2O3 | K2O | CaO | Na2O | MgO | H2O |
| Content (%) | 47.80 | 31.05 | 2.03 | 9.40 | 0.03 | 0.94 | 0.81 | 2.62 |
| Proportion Kg/M3 | Refractive index | Albedo | Moisture | dwb | Diameter ratio | Heat resistance | xsite |
| 280 | 1.60 | 70-80 | <1% | <1% | >60 | 1,000 ℃ | 2.82-2.9 |
Mica physical property:
| Degree of hardness: | In {001} on is 2-3, vertical {001} is 4 |
| Proportion: | 2.76-3.10g/cm 3 |
| Cleaves: | {001} cleaves extremely completely, some (110) and (010) crack principle |
| Color: | Light yellow, light green, sorrel |
| tiaohen: | Colorless |
| Transparency: | Transparently to translucent |
| Gloss: | Glassy luster, on present pearly luster |
| Shines the nature: | Does not have |
| Other: | The thin slice has the remarkable elasticity. The prosperous reason and the heat insulation is all extra-heavy |
Mica use: Uses many in the industry is the white mica, next
is the bronze mica. Its widespread application to chemical industry and so on
building materials profession, fire profession, fire-extinguishing, welding rod,
plastic, electric insulation, papermaking, bituminized paper, rubber, pearly
luster pigment. The superfine mica powder makes function padding and so on the
plastic, coating, paint, rubber, may enhance its mechanical strength,
enhancement toughness, is attaching the strength anti- aging and is
anti-corrosive and so on. Except that has the extremely high electric
insulation, the anti- acid and alkali corrodes, the elasticity, toughness and
skids the nature, heat-resisting sound-insulated, the thermal-expansion
coefficient small and so on outside the performance, also takes the lead to
promote the piece body two surfaces smoothly, the diameter thick big, the shape
rule, attaches the strength to be stronger than and so on the
characteristic.
In the industry mainly uses its
insulating property and the thermal stability, as well as acid resistance,
alkali resistance, resistant to compression and exhausted minute nature, serves
as the electrical equipment and the electrical engineering equipment and
materials insulation material; Next uses in to make the steam boiler, on the
smelting furnace stove window and the machinery components. The mica garrulous
and the mica powder may process the micabond paper, also may replace the mica
sheet to make each kind of cost to be inexpensive, thickness even insulation
material.
Physical property: The mica is one kind includes the
water the layered silicate mineral, the type very many, the mica powder has
uniquely is acidproof, bears the alkali, the chemical stability performance, but
also has the good insulation and the thermal stability, the corrosion
resistance.
Divides into according to the processing
method violates the law the mica, the aqueous method mica. The main
specification includes: 8-10 item, 10-20 item, 20-40 item, 40-60 item, 60-100
item, 100 item, 200 item, 325 item and so on.
