Mica - kodi mchere kuti? Kufotokozera ndi katundu wa Mica

Mica opezeka mu formations zachilengedwe mchere wa matanthwe a pansi padziko. Ndi thanthwe chiyambi chiphala, lomwe linakhazikitsidwa pa yozizira chiphalaphala chopangidwa ndi chitsulo chosungunula. Komanso Dziwani ndi kuti Mica - ichi ndi insulator kwambiri, si kuchititsa magetsi ndi kutentha.

kutanthauzira kwa chiphunzitso cha

Gulu la mchere ali pogawanikana pamawere wangwiro njira imodzi. Iwo amatha unagawika mbale zoonda olimba pokhalabe ndi elasticity, kusinthasintha ndi mphamvu.

Choncho, tinganene kuti Mica - ndi mchere kuti ali zowoneka amatikumbutsa galasi ndipo ali ndi kapangidwe ndi timibulu magawo. Ndi chifukwa Mbali imeneyi, komanso chifukwa lumikiza ofooka pakati pa mapaketi munthu zipangizo anapanga zina mankhwala katundu.

Kaya chakuti pali mitundu yosiyanasiyana ya mchere pansi kulingalira, ali ndi makhalidwe ofanana, monga:

• lamellar;
• woyambira pogawanikana pamawere;
• kuthekera unagawika zigawo zikuluzikulu abwino.

mitundu ya Mica

Potengera mipweya, n'zotheka kupereka gulu otsatirawa a mchere pansi kulingalira, akuti:

1. Magnesian-ferruginous Mica - biotite, phlogopite ndi lepidomelan.
2. Zotayidwa Mica - Paragon ndi muscovite.
3. Lifiyamu Mica - zinnwaldite, lepidolite ndi tayniolit.

Pali kufanizitsa ina ya mchere izi, kutanthauza mfundo "Mica mafakitale":

• zidutswa ndi Mica zazing'ono (kwa akufa ziwalo za ulimi Mica pepala);
• intumescent Mica - vermiculite analandira mwa calcination ya mchere ya;
• Mica.

Mbali ankaona igneous miyala

Mica - ndi mchere wa metamorphic, nyanja ndi miyala intrusive, ndi osakaniza ndi zambiri ndi mchere.

Phlogopite ndi muscovite ndi apamwamba zipangizo zamagetsi zokutira zitsulo, amene ali singasiyanitsidwe m'madera monga wailesi, magetsi ndi ndege. Makampani galasi Mwachitsanzo, si popanda lepidolite omwe la galasi kuwala.

Ndi Dziwani kuti chachikulu zofunika akamagwira ogwirizana Mica ndi micanite mbale, ntchito ngati pamwamba kwambiri magetsi ndi matenthedwe zinthu kutchinjiriza. A osaya ku zidutswa Mica ndi Mica analandira milled ntchito advantageously mu simenti, zomangamanga, mafakitale labala, kupanga mapulasitiki, utoto, etc.

Amagwiritsidwanso ntchito monga filler mu nyumba maganizo ndi nyimbo yabwino ntchito mu mapangidwe zikuwononga ndi chinyezi mkulu. Micas zagonjetsedwa kwa fractionation, ndipo malingana ndi zimene kukula kachigawo zipangizo opatsa katundu yeniyeni. Makamaka, mwina zayamba zinthu mikroslyuda anaumitsa, pambuyo chimene tikhale kukana kuti mapindikidwe aliyense, komanso kuti katundu alternating.

Mica-muscovite ali ndi kuwala imvi mtundu ndipo ntchito popanga zipangizo utoto, zomangamanga, mapulasitiki, zomatira, mankhwala ena omatira, mastics ndi zina zotero. D. Kuti konkire ndi phokoso chimateteza makhalidwe anawonjezera thereto vermiculite.

Komanso, Mica - mchere ndi m'mene katundu kukongoletsa, amene ntchito pa mbali zotsatirazi:

• kupanga moto zowonetsera;
• chilengedwe cha galasi othimbirira;
• zodzikongoletsera kupanga.

The zikuchokera ndi thanthwe akulowa mchere kuti?

Miyalayo - mwala Mica mu zikuchokera omwe wapezeka mu buku lalikulu. Iye ni mmodzi wa ambiri crystalline aggregates mchere achilengedwe. mwala kale ntchito m'munda yomanga.

Mawu "lubwe" lachokera ku Latin "Granum" omwe anamasuliridwa kuti "mbewu". mwala uwu chimagwiritsidwa ntchito ndi mapulani ndi okonza kwa zaka mazana angapo zapitazi, chifukwa chakuti iye ali zoterezi katundu monga mphamvu mawotchi, durability ndi kukana kwa chisanu, izo zikulumikizana bwino ndi katundu wake kukongoletsa.

Okoma maonekedwe a lubwe oyenera kunja cladding zinthu - yomanga embankments kapena chilengedwe misewu ndi zamkati (zinthu zosiyanasiyana za kukongola).

Iwo wapangidwa ndi khwatsi, feldspar, Mica mchere. Chiŵerengero zimakhudza mtundu ndi mphamvu ya mwala.

Kodi zimachitika?

Kutengera pa kukula tirigu, mitundu zotsatirazi lubwe, akuti:

• coarse mwala (pa 10 mm);
• sing'anga-grained lubwe (2-10 mm);
• chabwino-grained (osakwana 2 mm).

Miyalayo mtundu phale ukufanizidwa pafupifupi mithunzi yonse ya sipekitiramu wa. Mipikisano wachikuda chimanga - ndi feldspar, mitundu Mica lubwe mu silika wakuda ndipo amachititsa wothwanima mbewu translucent.

ubwino

Miyalayo - mwala, Mica mu zikuchokera zimene zimapangitsa izo cholimba poyerekeza ndi nsangalabwi otchuka. Zamgululi adalenga kuchokera mmenemo sadzataya katundu osati olumala kunja pamene opareshoni m'madera chokhala ndi nyengo kutentha kusiyana madigiri kuposa zana. Choncho, lubwe sakuopa shestidesyatigradusnyh chisanu kapena kutentha pamwamba madigiri 50, chimene chiri chofunika mu nyengo Russian. Komanso, mwala ndi zochepa kwambiri kusiyana ndi nsangalabwi chomwecho, atengeke kuukira mafangasi.

Lubwe, Mica, amene ali nawo mawonekedwe a muscovite ndi biotite, osati cholimba, komanso mwala fireproof. Umayamba kusungunula pa kutentha pamwamba 700 madigiri Celsius.

Komanso kuonedwa kuti ndi muyezo kudziwa mlingo wa mphamvu monga mayamwidwe chinyezi. Miyalayo umadutsa izo mpikisano onse.

Version za chiyambi cha dzina la Mica yowala

The buku loyamba la malipoti a mchere, amene anaonekera chitukuko European, wakhala "mbadwa" kwa Karelia. Mica, Kuwulura umene poyamba analembedwa buku chapadera cha zogulitsa kunja kwa West ndipo wakhala wa wolowa chachikulu cha dziko mu zaka XVII-XVIII. Umboni wa zimenezi ndi chiyambi cha dzina kuwala Mica - muscovite - (. XV-XVIII CC) dzina wakale wa dziko la likulu la dziko Russian - Muscovy. Choncho, tingathe kunena kuti iwo anali kudza kwa misika kumadzulo kwa Russia.

Malinga ndi buku la sayansi, maonekedwe a dzina ili akuti ndi nthawi pamene taxonomy awiri, bungwe la Swedish zachilengedwe Carl Linnaeus, German mineralogist Valerius n'kukagwiritsa Mica m'mafakitale chamutu wa lolingana yeniyeni gawo dzina, kutanthauza «Vitrum moscoviticum Wall». Kenako, dzina awiri dongosolo anakhalabe mawu okhawo chapakati cha akuti akufuna.

History Mica ntchito m'madera mafakitale

Milandu loyamba mchere izi, makamaka mmalo mwa zenera galasi anali analalikira Novgorod (X-XII CC.) Pa chitukuko cha chuma Karelia ndi Kola Peninsula. Ndiye Ivan Grozny anagonjetsa Novgorod ndi Pskov, amene anathandiza kuti womdziwa olamulira Muscovite ndi Mica.

Mu zaka za m'ma chakhumi ndi chisanu ndi chiwiri mu Karelia kale makampani Mica imene'yi otukuka. Malinga ndi kafukufuku boma chiyambi cha 1608 panali Moscow boma lamulo ponena za chopereka cha msonkho mchere yotengedwa kuchuluka kwa limodzi la magawo khumi la chonse pamodzi.

Development ndi kafukufuku wa Siberia m'zaka XVII zinachititsa kuti madipoziti latsopano atulukira Mica. kukhalapo kwake umboni Vladimir Atlasov mu 1683 kuti Aldan. madipoziti Kenako aiwala, ndipo zaka mazana awiri okha ndi makumi asanu (madzulo a Wamkulu kukonda dziko lako nkhondo) kuuweruza. Pa nthawi imeneyo anayamba ntchito Mica makamaka kwa zosowa za chitetezo cha dziko.

kuipa kawetedwe

Monga tanena kale, Mica - ndi mchere kuti akhoza kupanga mphamvu yaikulu za nkhaniyo. Komabe, ngakhale chikuzika katundu ntchito zake zosiyanasiyana ndi othandiza thanthwe khalidwe la porosity ndi brittleness. N'chifukwa chake Mica ntchito basi molumikizana ndi zigawo zina zimene samalani nkhani kukhulupirika ndi mphamvu mawotchi. Kupezeka kwa mchere izi miyala amachepetsa mphamvu ndipo durability, kukupangitsa kukhala kovuta pogaya ndi kupukuta.

The zogwirizana khwatsi, lubwe, Mica?

Kuti timvetse kamodzinso, tiyenera kupereka mafotokozedwe achidule aliyense wa mawu awa pa nkhani imeneyi.

Mica akutumikira mchere ndi ongokhala wopyapyala, mbale. particles izi gulu mosavuta linagawanika. Iwo mandala mdima mafunde ndi chithunzithunzi a. Mica akutumikira constituent ya lubwe ndi miyala ina. chitukuko zachitika lotseguka kapena migodi. Pa nthawi yomweyo ntchito kabotolo. timibulu Mica amasankhidwa kuchokera m'matanthwe thanthwe yekha pamanja. Komanso njira yapangidwa kaphatikizidwe ake mafakitale.

Khwatsi - mchere, osati gawo chabe la Miyalayo, komanso pafupipafupi nawo mu mawonekedwe osiyana. timibulu zake ndi kukula kuchokera millimeters ochepa mpaka mamita angapo. Transparent chimake cha mchere iyi akutchedwa thanthwe galasi ndi woyera - yamkaka khwatsi. Yotchuka kwambiri ndi mandala wofiirira khwatsi - ametusito. Pali pinki, ndi buluu, ndipo ambiri mitundu ina ya mchere, amene amagwiritsidwa ntchito makamaka kupanga zibangili.

Miyalayo - thanthwe, chomwe ndi mbewu ya mchere angapo monga Mica, feldspar ndi khwatsi. Izo zifika ku pinki, imvi, wofiira. Iye akanakhoza Nthawi zambiri m'mizinda, monga amachita cladding wa ena nyumba, anapanga zitsulo ndi zipilala ndi kufalitsa embankments mitsinje.
