I-Mica yenye yeeminerali eziphambili ezenza ilitye, kwaye ikristale inesakhiwo esinemaleko ngaphakathi, ngoko ke ibonisa i-crystal flake ene-hexagonal. I-Mica ligama eliqhelekileyo kwiqela le-mica lamaminerali, ngokukodwa kubandakanywa i-biotite, i-phlogopite, i-muscovite, i-lepidolite, i-sericite, kunye ne-lepidolite.
Iipropati zentsimbi kunye noLwakhiwo lweziMbiwa
I-Mica yiminerali ye-aluminosilicate kwaye ihlulwe ibe ngamacandelwana amathathu: i-muscovite, i-biotite kunye ne-lepidolite. I-Muscovite ibandakanya i-muscovite kunye ne-sodium mica engaphantsi kwesiqhelo; i-biotite iquka i-phlogopite, i-biotite, i-manganese biotite; i-lepidolite sisikali esilungileyo semica eyahlukeneyo etyebileyo kwi-lithium oxide; i-sericite iyiminerali yodongwe eneempawu ezithile zendalo ye-muscovite ene-fine-grained. Kwishishini, ngakumbi kwishishini lombane, i-muscovite kunye ne-phlogopite zisetyenziswa ngokuqhelekileyo. Amacandelo aphambili e-mica yi-silicon, i-aluminium, i-potassium, i-magnesium, i-lithium, i-crystal yamanzi kunye nexabiso elincinci lesinyithi, i-manganese, i-titanium, i-chromium, i-sodium, i-calcium, njl. I-biotite kunye ne-phlogopite zineempawu zemagneti ezibuthathaka, kwaye amanye amaphepha e-mica anokuthi afakwe kunye nokungcola okufana nentsimbi kunye ne-manganese kwaye aneempawu ezithile ezibuthathaka zemagneti. Ubunzima be-Mohs yi-2 ~ 3, ubuninzi be-2.7 ~ 2.9g / cm3, iiminerali eziqhelekileyo ezinxulumene nazo ziyi-pyrite, i-tourmaline, i-beryl, i-feldspar, i-quartz, i-spinel, i-diopside, i-tremolite, njl., phakathi kwayo i-yellow Iron ore, i-tourmaline, i-spinel, i-diopside , njl. zineempawu ezibuthathaka zemagneti.
Iindawo zesicelo kunye nezalathi zobugcisa
I-Muscovite ineempawu ezintle zomzimba kunye neekhemikhali ezifana namandla aphezulu e-dielectric, ukuxhathisa okuphezulu, ilahleko ye-dielectric ephantsi, i-arc resistance, i-corona resistance, i-texture enzima, amandla aphezulu omatshini, ukumelana nobushushu obuphezulu, ukuxhathisa kwe-asidi kunye ne-alkali, ngoko isetyenziswa ngokubanzi kwishishini. Inoluhlu olubanzi losetyenziso; iipropathi eziphambili ze-phlogopite mica zingaphantsi kancinci kwi-muscovite mica, kodwa inokumelana nokushisa okuphezulu kwaye iyinto efanelekileyo yokukhusela ukushisa; fragment mica ibhekisa kwigama jikelele lemica entle esembiwayo kunye nentsalela eveliswa ngokulungiswa kunye nokufakwa kwetafile. ; I-Lepidolite, ekwabizwa ngokuba yi-phosphomica, yimathiriyeli ekrwada ye-lithium, kwaye i-sericite isetyenziswa kakhulu kwirabha, iiplastiki, isinyithi, izithambiso, njl.
ITekhnoloji yoLungiso
Ukuxhamla kunye nokuhlanjululwa
I-beneficiation kunye neendlela zokuhlanjululwa kwe-mica ziyahluka ngokwendalo kunye nohlobo. I-Flake mica ngokuqhelekileyo yamkela ukuhlenga-hlengisa ngesandla, ukunyanzeliswa kokukhuhlana, ukuzuza imilo, njl. njl.; i-mica etyumkileyo ithatha ukwahlukana komoya kunye nokuphaphatheka, i-biotite kunye ne-phlogopite zinokuthatha ulwahlulo olomeleleyo lwemagnethi, i-muscovite, i-lepidolite kunye ne-sericite ziqulethe iimpawu zemagneti ezibuthathaka. Ukungcola nako kunokususwa ngokuhlukana okunamandla kazibuthe.
01 Ukukhetha (ukwalatha) ukhetho
Kubuso bemigodi okanye kwimfumba ye-ore emgodini, i-mica ehlulwe kwi-monomer ikhethiwe, kwaye ifanelekile ngokubanzi kwi-flake mica enkulu.
02 Uncedo lwefriction
Ngokomahluko phakathi kwe-coefficient ye-sliding friction ye-crystal mica flaky kunye ne-rolling coefficient ye-ganggue ejikelezayo, i-crystal mica kunye ne-ganggue iyahlukana. Esinye sezixhobo ezisetyenzisiweyo sisilungelelaniso sepleyiti etyibilikayo.
03 Ubume benzuzo
Ngokwemilo eyahlukeneyo ye-mica crystals kunye ne-ganggue, ukukwazi ukudlula kwi-gap ye-sieve okanye i-sieve hole ngexesha le-sieving iyahluka, ukwenzela ukuba i-mica kunye ne-ganggue zihlulwe.
04 Ukukhetha umoya
Emva kokuba isanti kunye negrabile zityunyuziwe, i-mica ngokusisiseko ikwimo yeeflakes, ngelixa iiminerali ze-ganggue zikwimo yeengqungquthela ezinkulu. Emva kokuhlelwa kwamanqanaba amaninzi, izixhobo ezikhethekileyo zisetyenziselwa ukwahlukana komoya ngokomahluko kwisantya sokumiswa emoyeni.
05 Ukuphaphatheka
Okwangoku, kukho iinkqubo ezimbini zokujikeleza: enye yi-flotation ye-mica kunye nabaqokeleli be-amine kwindawo ene-acidic; enye i-flotation kunye nabaqokeleli be-anionic kwi-alkaline medium, efuna ukuncitshiswa ngaphambi kokukhethwa, kwaye kufuneka ikhethwe amaxesha amaninzi.
06 Ukwahlulwa kwemagnethi
I-Biotite kunye ne-phlogopite zineempawu ezibuthathaka zamagnetic kwaye zinokukhethwa ngendlela enamandla yamagnetic; i-iron oxide kunye nokungcola kwe-iron silicate zihlala zihambelana ne-muscovite, i-sericite kunye ne-lepidolite, enokuthi isuswe kwakhona ngokuhlukana okunamandla kwamagnetic. Isixhobo sokwahlula imagnethi ikakhulu sibandakanya iirola zemagnethi ezomileyo nezimanzi, izahluli zepleyiti ezinozibuthe kunye neringi ethe nkqo yezahluli zemagnethi eziphakamileyo.
Xobula
Ukukrazula i-mica ekrwada kumaphepha e-mica ezinto ezahlukeneyo kubizwa ngokuba yi-mica peeling. Okwangoku, kukho iindlela ezintathu zokuxobula, ezizezezandla, zoomatshini kunye nezomzimba kunye neekhemikhali, ezisetyenziselwa ukusetyenzwa njengamashiti ashinyeneyo, amashiti amancinci, kunye ne-tube mica.
Ukugaya okucokisekileyo kunye ne-ultra-fine
Kukho iintlobo ezimbini zemveliso yokusila kakuhle kunye nokusila kwe-ultra-fine ye-mica, indlela eyomileyo kunye nendlela emanzi. Ukongeza kwisixhobo sokutyumza kunye nokusila, indlela eyomileyo nayo ifuna ukuxhotyiswa ngezixhobo ezifana nokuhlola kunye nokuhlelwa komoya. Imveliso emanzi isebenzisa izixhobo ezahlukeneyo zokusila ezimanzi, kwaye itekhnoloji yokusila emanzi yeyona ndlela yokuphuhlisa ukuveliswa komgubo ocolekileyo wemica.
Ukuguqulwa komphezulu
Ukuguqulwa komphezulu we-mica powder kunokwahlulwa kube ziinkqubo ezimbini: ukuguqulwa komphezulu we-organic kunye nokuguqulwa kwe-inorganic surface coating. Imveliso ye-mica elungisiweyo inokuphucula amandla omatshini wezinto eziphathekayo, ukunciphisa izinga lokunciphisa ukubunjwa, umphumo obonakalayo obonakalayo kunye nokuphucula ixabiso lesicelo, njl.
