General Introduction of mica
1.Mica is a kind of rock-forming minerals. Its form is platelike or flaky.The colour is variable with the differences of chemical composition. Mainly Fe content increase will make the colour be darker.
2. The characteristics of mica contains: insulation,high temperature resistant,lustrous appearance, stable physical and chemical property,good heat insulation, excellent elasticity and high toughness etc.
Particle Size of mica
It contains 3-5mm,1-3mm,15mesh,20mesh,40mesh,60mesh,80mesh ,100mesh,200mesh,325 mesh ,400 mesh etc.
Physical Property of mica
Diameter-thickness. Ratio | Whiteness | Refractive Index | Specific Gravity (g/cm3) | PH | Moisture | Sand Content | Colour |
1:30 | 50-70 | 1.58 | 2.8 | 6.5-7.5 | ≤0.5% | ≤1.0% | Silver white |
Chemical Composition of mica

Application of silver mica
Muscovite is used in industry mostly, the second is phlogopite.Mica is used widely in building materials industries, fire-fighting industries, fire extinguishing agent, electric welding rod, plastics, electric insulation, papermaking, asphalt paper,rubber,pearl pigment etc.
- Q: A chemical problem with refractory materials
- No, in junior high school may be exposed to AlN aluminum nitride, high temperature resistant new ceramic, water will react...
- Q: What is the principal part of silicious refractory material
- lightweight silica bricks, product with fused quartz, the silicon?dioxide content is generally greater than 93%, including silica?brick silicious refractory SiO2 as a main component of refractory products
- Q: What the fireproofing materialare of the refractory kettle and where they can be sold?
- Many places sell these. Nearly 10 years, can't brun when it is dry, adsorption. You can also baidu these materials. Heat transfer evenly, feldspar, clay and other raw materials with a ceramic products. Traditional casserole can not resist heat difference and also can withstand for 100 high temperature without crack. Aiming at the problem of traditional casserole, easy to crack and air permeability, people joined the spodumene on raw material, produce a high-temperature resistance casserole. It is produced after the high temperature burning makes an earthenware pot to keep the original advantages. Hebei has many places to sell these materials and is also relatively cheaper. The traditional casserole has features of not easy to transfer heat's quartz and slow cooling. Due to production technology and raw materials, it greatly improves the casserole' practicability after research and improvement.
- Q: Which industry does the metallurgy and thermal insulating and refractory material belong to?
- Metallurgical industry and refractory industry.
- Q: What are the models of bauxite with high alumina?
- China Ferrous Metal Industry Corporation released the industry standard of bauxite (YS / T78-94) in 1994. According to this standard, bauxite can be divided to sedimentary diaspore, stacked type diaspore and lateritic gibbsite. According to the chemical composition, it can be divided into nine trade marks as LK12-70, LK8-65, LK5- 60, LK3-53, LK15-60, LK11-55, LK8-50, LK7-50 and LK3-40. In addition to the provisions of chemical composition of bauxite, the standard also requires that the water of sedimentary diaspore shall not exceed 7% and water of stacked type diaspore and lateritic gibbsite shall not exceed 8%. Moreover, particle size of bauxite should be not greater than 150mm. Bauxite shall not be mixed with clay, limestone and other debris.
- Q: How long is the fire endurance of the rock wool board?
- The rock wool board takes the basalt as raw material and is processed into artificial inorganic fiber through high temperature melting, which is light in weight, non-combustible, heat absorptive, small in thermal conductivity. The initial development in construction is a common type of application used for industrial buildings, which should be consistent with the requirements of "building insulation application categories and basic requirements" . In June 1981 the pre-launch succeeds. The rock wool board is a new type of insulation, burning compartment and sound-absorbing material. Generally the fire resistance of the rock wool board is 140-180 degree within two hours, It is best not to exceed this safe period, in order to avoid security risks.
- Q: How is refractory material made?
- It is made from polyester.
- Q: What are the differences between first-level fire-resistant materials and second-level fire-resistant materials?
- 1, these refer to fire resistance rating of building materials. 2, As for steel, elements that used in different parts should reach different duration of fire resistance according to fire resistance rating. For example, fire resistant pillars of first level can endure fire within 3 hours; the second level, 2.5 hours; the third level, 2 hours. With respect to beams, three levels of fire resistance are included.
- Q: How many levels are there in the classification of PP fireproof materials?
- PP fireproof materials level V-0: After two 10-second fame tests on the sample, the flame extinguishes within 30 seconds. Inflamer can not drop. V-1: After two 10-second flame tests on the sample, the flame extinguishes within 60 seconds. Inflamer can not drop. V-2: After two 10-second flame tests on the sample, the flame extinguishes within 60 seconds. Inflamer can drop.
- Q: I wanna ask about the thermal insulation material fire resistant level?
- 1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 Level A insulation material is only for fireproofing, but its thermal insulation performance is not better than organic XPS \\ EPS and other materials.
