China’s relatively narrow application areas in recent years has been able to produce six categories, nearly 30 varieties. Solutions to enhance research and improve the comprehensive utilization and expanding applications, broaden the market trends from the general trend, as large crystals of synthetic mica success, the world’s demand for large mica will be gradually reduced, and therefore the exploitation of natural mica large amount will gradually decrease, but the demand will be on the mica fragments continue to increase. the world’s existing high-quality mica still far short of needs, the development of synthetic mica is accelerated. current consumption structure of mica has changed, it is estimated that worldwide demand for mica will be an annual 4.6% rate continued to decline, while demand for crushed mica at an average annual growth rate of 1.5%. mica products —- utilization wet mica powder mica and mica paper and deep-processed products are more popular on the international market products in recent years, domestic demand will gradually reduce the mica sheet, mica tube feeding to maintain a balance of requirements, chip capacitors and thick film loaded with saturated mica and other basic of natural mica flakes are generally replaced by alternative materials, but as mica utilization of products, mica paper and mica, and deep-processing products such as mica insulation products, mica paper began selling electrical appliances (1) mica-paper market to determine the electrical machinery sector has long been the main insulating material with mica mica paper instead of mica flakes. 1987 China’s new power generation capacity of 9.2 million kilowatts, generally by adding 100,000 kilowatts generating capacity would need to calculate the consumption of five tons of mica paper, mica paper, about 460 tons. the future of our energy industry is the focus of development, planned to reach an annual output of 10 million kilowatts of generating units capacity, mica paper per year is not less than 500 tons, totaling 2500 tons. In addition, China’s installed power generation capacity in 1987 reached 100 million kilowatts, by 20-30% if the consider replacement of maintenance, repair of mica paper is also required considerable addition, there are a large number of industrial, household appliances also requires a lot of insulation board and other products. the domestic market, promising mica paper (2) Mica national welding market mica production each year about 1.5 million tons of asphalt felt paper with mica 14 million tons, fire equipment 2,000 tons with mica, together with new and innovative applications of mica, from the development trend, the requirements may mica further growth. Open Category: Chemical, mica, Inuyasha, mineral, quartz 2. tail cat (transfiguration before), an emergency will directory help edit Baike card is a rock-forming mineral mica, usually hexagonal or diamond was ######## plates, sheets, columnar crystal. Color changes with the chemical composition varies, mainly with the Fe content increases and becomes deeper. Mica is characterized by the insulation, high temperature, shiny, physical and chemical properties and stability, good insulation, elasticity and toughness. Most used in industry is muscovite, followed by the mica. Its widely used in building materials industry, the fire industry, fire extinguishing agents, welding, plastics, electrical insulation, paper, bitumen paper, rubber, pearlescent pigments and other chemical industries. Mica is also animation as a character name appears. mica tourmaline, apatite, beryl, and ilmenite, etc. Phlogopite deposits in veins that often appear in apatite, tremolite, diopside, calcite, carbonate and feldspar and other minerals. Chopped fine muscovite mica deposits in general account for 50 to 70%, 10% K-feldspar and quartz about trace minerals are magnetite and limonite. The purpose of mineral mica mineral characteristics are aluminum silicate minerals, with continuous layered silicate structure. Divided into three sub-categories: muscovite, biotite and lepidolite. Muscovite mica and its subspecies, including (sericite) and rare paragonite; biotite including phlogopite, biotite, iron and manganese black biotite mica; lithium oxide lithium-mica is rich in a variety of small mica scales. Industry in particular is commonly used in the electrical industry muscovite and phlogopite. Muscovite the chemical formula for KAl2 [AlSi3O10] [OH] 2, which SiO2 45.2%, Al2O3 38.5%, K2O 11.8%, H2O 4.5%, also containing a small amount of Na, Ca, Mg, Ti, Cr, Mn, Fe, and F and so on. Phlogopite chemical formula KMg3 [AlSi3O10] [F, OH] 2, which K2O 7 ~ 10.3%, MgO of 21.4 ~ 29.4%, Al2O3 of 10.8 ~ 17%, SiO2 of 38.7 ~ 45%, H2O 0.3 ~ 4.5% , containing a small amount of Fe, Ti, Mn, Na and F and so on. a, crystal, crystal mica mostly monoclinic, books were stacked plate-like or crystal form, with six for the development of a complete surface of the diamond or hexagonal crystals, sometimes the formation of pseudo hexagonal prismatic crystals. b, cleavage, or the pressure of playing as well as with the cleavage of mica can be stripped points. Muscovite can be theoretically divided into 10 or so stripping, phlogopite peelable into thin slices about 5 or 10. Mica crystals hidden cleavage, and the pressure is like playing as. c, color, gloss and transparency of mica flakes is generally colorless and transparent, but often stained green, brown, yellow and pink and other colors; glass, luster, cleavage appear before pearl luster. Phlogopite is usually yellow, brown, dark brown or black; glass luster, cleavage appear before pearls or semi-metallic luster. Muscovite transparency 71.7 ~ 87.5%, phlogopite 0 to 25.2%. d, hardness and elasticity of muscovite Mohs hardness of 2 to 2.5, phlogopite 2.78 ~ 2.85; muscovite elasticity (1475.9 ~ 2092.7 × 106Pa (15050 ~ 21340kg/cm2), phlogopite for (1394.5 ~ 1874.05 ) × 106Pa (14220 ~ 19110kg/cm2 mica become a great horse, foot flame, you can volley battle, aggressive. good line monster class. once a witch Tsui sub partner, the soul of the four sub-Chui Yu-injection death, mica become a partner Chuyao village and coral Chuyao together and finally become a partner in the coral’s brother amber. Open Category: animation, pets, cartoon characters, Inuyasha, cats 3 Chinese words help edit mica 1 ore name commonly known as Melaleuca paper. hexagonal crystals often as ######## sheet, a collection of scaly. thin and flexible, glass and shiny, translucent, white, black, different shades of green or brown, etc. are not conductive, insulating, high temperature, corrosion resistant to moisture. muscovite for medicinal. Temple mica slide, Bao Liu dry dry cliff. (4) snow Tang Yuan Zhen : Fu Help edit the mica , Lingshou quality within the rock strata two-Pacific, rocks rich in mica minerals, the texture of the exploration department, crushed mica reserves of 1.7 million tons of ore of high grade, good quality, is the largest The origin of crushed mica, and because the development earlier, becoming the largest processing base of mica and the largest exporter of mica. deposit types and their distribution 1, deposit type deposits into muscovite mica deposits of industrial and phlogopite deposits in two categories, Each category can be divided into two subgroups each, plus small pieces of mica mica mine on the crushed mica, sericite mineral surveys. So far, Hebei Lingshou of Lubo Village is China’s largest pieces of mica and biotite to the largest production and processing. After detailed investigation, proved Township, Shan Tam Hebei Lingshou door broken mica mine in Inner Mongolia, Liaoning, Hubei and other places that sericite mine, crushed mica and sericite in the industrial application of research has also made progress. China in the 1950s to the mid-1970s, had to muscovite, phlogopite as a strategic resource, the first of four Chuandan Ba mica mining ore, after Xinjiang, Inner Mongolia, Shanxi, Hebei, Shandong, Henan, Shaanxi, Yunnan provinces, autonomous regions and mica mines have been mined. Major state-owned mines have Altay, four Chuandan Ba, Ula, Inner Mongolia and other mines in your soil, there are hundreds of counties do, towns and individual mines. 1978 years ago, the annual production of industrial raw materials, mica is 1 700 ~ 2 500t, 1978 years later, production has decreased due to mica a fundamental change in consumption due to structure. Characteristics of the mineral composition of ore minerals muscovite pegmatite minerals of the major minerals feldspar, feldspar, quartz and muscovite <a href="http://436100.info/view.php?id=95231"><strong>Cheap Reebok L.A. Dodgers Royal Blue Ventilator Shoes | Cheap ...</strong></a> and other secondary minerals are biotite, almandine, electricity insulation on the gas industry. Mica fragments and powder used as fillers. Extraction of lithium or lithium-mica major mineral raw materials. As the large mineral mica crystals, colorful, has long been used by humans. Ancient Chinese records in its title alone: the skin with flowers, ice days, days of leather, in gold, old gold scraping, Melaleuca paper, per side, red rice and hung black cloud, etc. Mogao Grottoes in Dunhuang Cave 112 Don pigment used in flash illuminated by the X-ray diffraction analysis, natural muscovite by crushing grinding. Color with excellent results. Although China has been recognized early and the use of muscovite and phlogopite, mica deposits but exploration work in the formal establishment of the PRC after 1952 have been from the four-Chuan Danba and Inner Mongolia soil deposits to your Siniora muscovite a census of exploration and achieved good results. Shanxi Fanshi 1958 held a national meeting of mica, mica decided to vigorously carry out the survey and prospecting work, then, Altay mica deposits found in the mica resource development in China played a big role, but also for the census mica deposits exploration work and accumulated experience. Subsequently, magnesium phengite Jiangsu East China Sea deposits discovered and exploited by industry in China’s industrial added a new species of mica. Inner Mongolia, the Urals, the Dabie Mountains, Qinling, Liaoning, Sichuan and Yunnan, have been found in deposits of mica, expanded mica resources. Since the 1980s, building materials, mining and other sectors mica mica (mica) is the most widely distributed rock-forming minerals, potassium, aluminum, magnesium, iron, lithium aluminum silicate layered structure in general. Mica common polymorphism, which is a monoclinic system are common, followed by the trigonal system, and the remaining rare. Mica-group minerals, the most common mineral species are biotite, muscovite, phlogopite, lithium mica, sericite, etc. Mica was usually six or ######## diamond plates, sheets, columnar crystal. Color changes with the chemical composition varies, mainly with the increase in iron content and dark. Muscovite was colorless and transparent or light-colored; biotite is black to dark brown, dark green and other colors; phlogopite yellow, brown, green or colorless; lepidolite was purple, rose red to gray. Glass, luster, cleavage plane was pearl luster. Mohs hardness is generally 2 to 3.5, the proportion of 2.7 to 3.5. Parallel to the very bottom of the cleavage completely. Muscovite is a widely distributed rock-forming minerals, one of the three rocks in both outputs. Pelitic rocks during regional metamorphism in low-level can be formed sericite, slightly higher metamorphic grade, as muscovite. Acidic pegmatite magma crystallization and the role of the late stage, has generated a lot of muscovite. From high to low temperature alteration in the process, can also be generated. The so-called greisen alteration is the high temperature one can form a large number of muscovite. Sericitization role in the so-called low-temperature alteration, one can form a large number of sericite. Muscovite weathering broken into very fine scales, can become clastic sediments in the debris, it can be one of the mineral composition of mudstone. Muscovite and phlogopite have good electrical insulation and not heat, acid, alkali and pressure resistance, which is widely used to produce electronic, electrical Tags: moncler jacket, moncler ski pa Posted in Uncategorized RSS | Respond | Trackback < |
