I-Mica yenye yezona minerali ziphambili ezenza amatye, kwaye i-crystal inesakhiwo esinomgangatho ngaphakathi, ngoko ke iveza i-crystal ene-hexagonal flake. I-Mica ligama eliqhelekileyo leqela leeminerali ze-mica, kuquka i-biotite, i-phlogopite, i-muscovite, i-lepidolite, i-sericite, kunye ne-lepidolite.
Iipropati ze-ore kunye nolwakhiwo lwezimbiwa
IMica yiminerali ye-aluminosilicate kwaye yahlulwe yangamaqela amathathu: i-muscovite, i-biotite kunye ne-lepidolite. IMuscovite iquka i-muscovite kwaye i-sodium mica engaphantsi kakhulu; i-biotite iquka i-phhlogopite, i-biotite, i-manganese biotite; i-lepidolite sisikali esincinci se-mica eyahlukeneyo etyebileyo kwi-lithium oxide; i-sericite yiminerali yodongwe eneempawu ezithile ze-muscovite yendalo ecolekileyo. Kwishishini, ingakumbi kushishino lombane, i-muscovite kunye ne-phhlogopite zisetyenziswa rhoqo. Izinto eziphambili ze-mica yi-silicon, i-aluminium, i-potassium, i-magnesium, i-lithium, amanzi ekristale kunye nenani elincinci le-iron, i-manganese, i-titanium, i-chromium, i-sodium, i-calcium, njl. IMica inomqhekezo ogqibeleleyo kwaye inokuxotyulwa. Phakathi kwazo, i-biotite kunye ne-phhlogopite zineempawu zemagnethi ezibuthathaka, kwaye amanye amaphepha e-mica anokufakwa kwizinto ezingcolileyo ezifana ne-iron kunye ne-manganese kwaye aneempawu ezithile zemagnethi ezibuthathaka. Ubunzima beMohs buyi-2 ~ 3, ubuninzi buyi-2.7 ~ 2.9g/cm3, iiminerali ezinxulumene nazo eziqhelekileyo yi-pyrite, i-tourmaline, i-beryl, i-feldspar, i-quartz, i-spinel, i-diopside, i-tremolite, njl.njl., phakathi kwazo i-yellow Iron ore, i-tourmaline, i-spinel, i-diopside, njl.njl. zineempawu zemagnethi ezibuthathaka.
Iindawo zokusetyenziswa kunye nezalathisi zobugcisa
IMuscovite ineempawu ezintle zomzimba nezekhemikhali ezifana namandla aphezulu e-dielectric, ukumelana okuphezulu, ukulahleka okuphantsi kwe-dielectric, ukumelana ne-arc, ukumelana ne-corona, ubume obuqinileyo, amandla aphezulu oomatshini, ukumelana nobushushu obuphezulu, ukumelana ne-asidi kunye ne-alkali, ngoko ke isetyenziswa kakhulu kushishino. Ineendlela ezahlukeneyo zokusetyenziswa; iimpawu eziphambili ze-phhlogopite mica zingaphantsi kancinci kune-muscovite mica, kodwa inokumelana nobushushu obuphezulu kwaye sisixhobo esihle sokukhusela ubushushu; i-fragment mica ibhekisa kwigama eliqhelekileyo le-mica entle efunyanwa kunye nezinto eziseleyo eziveliswa ngokucutshungulwa kunye nokufakwa kwithebhulethi. ; I-Lepidolite, ekwaziwa ngokuba yi-phosphomica, sisixhobo esiluhlaza seminerali sokukhupha i-lithium, kwaye i-sericite isetyenziswa kakhulu kwirabha, iiplastiki, i-metallurgy, izinto zokuthambisa, njl.
Itekhnoloji yokucubungula
Ukuzuza kunye nokuhlanjululwa
Iindlela zokucoca nokulungisa i-mica ziyahluka ngokwendalo kunye nohlobo lwayo. I-Flake mica idla ngokusebenzisa ukuhluzwa ngesandla, ukuhluzwa kwe-friction, ukuhluzwa kwesimo, njl.njl.; i-mica etyumkileyo isebenzisa ukwahlulwa komoya kunye nokuqubha, i-biotite kunye ne-phhlogopite zinokusebenzisa ukwahlulwa okunamandla kwe-magnetic, i-muscovite, i-lepidolite kunye ne-sericite ziqulathe iimpawu ze-magnetic ezibuthathaka. Ukungcola kunokususwa ngokusebenzisa ukwahlulwa okunamandla kwe-magnetic.
01 Ukukhetha (ukukhomba)
Kubuso bomgodi okanye kwinqwaba yentsimbi emngxunyeni, kukhethwa i-mica ehlukanisiweyo ne-monomer, kwaye ngokubanzi ifanelekile kwi-mica enkulu eneziqwenga.
02 Ukuzuza ingxabano
Ngokomahluko phakathi kwe-sliding friction coefficient ye-flaky mica crystal kunye ne-rolling friction coefficient ye-round gangue, i-mica crystal kunye ne-gangue zahlulwe. Esinye sezixhobo ezisetyenzisiweyo yi-slant plate sorter.
03 Ukuphucula iMilo
Ngokweemilo ezahlukeneyo zeekristale ze-mica kunye ne-gangue, amandla okudlula kwisithuba sesihluzo okanye umngxuma wesihluzo ngexesha lokusiva ahlukile, ukuze i-mica kunye ne-gangue zahlulwe.
04 Ukukhetha umoya
Emva kokuba isanti kunye negrabile zityunyuziwe, i-mica ngokuyintloko ikwimo yeeflakes, ngelixa iiminerali ze-gangue zikwimo yeesuntswana ezinkulu. Emva kokuhlelwa kwamanqanaba amaninzi, kusetyenziswa izixhobo ezikhethekileyo zokwahlula umoya ngokwehluka kwesantya sokumisa kwindlela yomoya.
05 Ukudada
Okwangoku, kukho iinkqubo ezimbini zokuqubha: enye kukuqubha kwe-mica kunye nabaqokeleli be-amine kwindawo ene-asidi; enye kukuqubha kunye nabaqokeleli be-anionic kwindawo ene-alkaline, ekufuneka isuswe i-slime ngaphambi kokukhethwa, kwaye kufuneka ikhethwe amaxesha amaninzi.
06 Ukwahlulwa kweMagnetic
I-Biotite kunye ne-phhlogopite zineempawu zemagnethi ezibuthathaka kwaye zinokukhethwa ngendlela enamandla yemagnethi; ukungcola kwe-iron oxide kunye ne-iron silicate kuhlala kunxulunyaniswa ne-muscovite, i-sericite kunye ne-lepidolite, enokususwa ngokwahlukana okunamandla kwemagnethi. Izixhobo zokwahlula imagnethi ziquka ikakhulu ii-roller zemagnethi ezomileyo nezimanzi, ii-plate magnetic separators kunye nee-vertical ring high gradient magnetic separators.
Xobula
Ukuxobula i-mica eluhlaza kwiishiti ze-mica ezahlukeneyo kubizwa ngokuba yi-mica peeling. Okwangoku, kukho iindlela ezintathu zokuxobula, ezizezesandla, ezoomatshini nezomzimba kunye nezekhemikhali, ezisetyenziselwa ukucubungula ezifana namaphepha amakhulu, amaphepha amancinci, kunye ne-tube mica.
Ukugaya kakuhle nangokucokisekileyo
Kukho iintlobo ezimbini zemveliso yokusila okucolekileyo kunye nokusila okucolekileyo kakhulu kwe-mica, indlela eyomileyo kunye nendlela emanzi. Ukongeza kwizixhobo zokutyumza nokusila, indlela eyomileyo ikwafuneka ixhotyiswe ngezixhobo ezifana nokuhlola kunye nokuhlelwa komoya. Imveliso emanzi isebenzisa izixhobo ezahlukeneyo zokusila ezimanzi, kwaye iteknoloji yokusila emanzi yeyona ndlela iphambili yophuhliso kwimveliso yepowder ecolekileyo ye-mica.
Ukuguqulwa komphezulu
Ukuguqulwa komphezulu we-mica powder kunokwahlulwahlulwa zibe ziinkqubo ezimbini: ukuguqulwa komphezulu we-organic kunye nokuguqulwa kwe-inorganic surface coating. Imveliso ye-mica eguquliweyo inokuphucula amandla oomatshini wezinto, inciphise izinga lokuncipha kokubumba, isiphumo esihle sokubona kunye nokuphucula ixabiso lokusetyenziswa, njl.
