I-Mica ingenye yamaminerali akha amatshe amakhulu, futhi i-crystal inesakhiwo esinezingqimba ngaphakathi, ngakho-ke iveza i-crystal flake ene-hexagonal. I-Mica yigama elivamile leqembu le-mica lamaminerali, ikakhulukazi i-biotite, i-phlogopite, i-muscovite, i-lepidolite, i-sericite, ne-lepidolite.
Izakhiwo ze-Ore kanye nesakhiwo samaminerali
I-Mica iyiminerali ye-aluminosilicate futhi ihlukaniswe ngamaqembu amathathu: i-muscovite, i-biotite ne-lepidolite. I-Muscovite ihlanganisa i-muscovite kanye ne-sodium mica engavamile kakhulu; i-biotite ihlanganisa i-phlogopite, i-biotite, i-manganese biotite; i-lepidolite iyisilinganiso esihle se-mica ehlukahlukene ecebile ku-lithium oxide; i-sericite iyiminerali yobumba enezici ezithile ze-muscovite ehlanzekile yemvelo. Embonini, ikakhulukazi embonini kagesi, i-muscovite ne-phlogopite ivame ukusetshenziswa. Izingxenye eziyinhloko ze-mica yi-silicon, i-aluminium, i-potassium, i-magnesium, i-lithium, amanzi e-crystal kanye nenani elincane lensimbi, i-manganese, i-titanium, i-chromium, i-sodium, i-calcium, njll. I-Mica ine-cleavage ephelele futhi ingaxetshulwa. I-biotite ne-phlogopite zinezici ezibuthakathaka kazibuthe, futhi amanye amashidi e-mica angase ashumekwe nokungcola okufana nensimbi ne-manganese futhi abe nezakhiwo ezithile ezibuthakathaka kazibuthe. Ubulukhuni be-Mohs bungu-2 ~ 3, ubukhulu bungu-2.7 ~ 2.9g / cm3, amaminerali ajwayelekile ahlobene yi-pyrite, i-tourmaline, i-beryl, i-feldspar, i-quartz, i-spinel, i-diopside, i-tremolite, njll., phakathi kwayo okuphuzi kwe-Iron ore, i-tourmaline, i-spinel, i-diopside , njll. zinezakhiwo ezibuthakathaka kazibuthe.
Izindawo zokufaka izicelo kanye nezinkomba zobuchwepheshe
I-Muscovite inezici ezinhle zomzimba namakhemikhali ezifana namandla aphezulu e-dielectric, ukumelana okuphezulu, ukulahlekelwa kwe-dielectric ephansi, ukumelana ne-arc, ukumelana ne-corona, ukuthungwa kanzima, amandla aphezulu emishini, ukumelana nokushisa okuphezulu, ukumelana ne-asidi kanye ne-alkali, ngakho-ke isetshenziswa kabanzi embonini. Inokusetshenziswa okubanzi; izakhiwo eziyinhloko ze-phlogopite mica zingaphansi kancane kune-muscovite mica, kodwa inokumelana nokushisa okuphezulu futhi iyinto enhle yokuvimbela ukushisa; i-fragment mica ibhekisela egameni elivamile le-mica emihle embiwayo kanye nezinsalela ezikhiqizwa ngokucubungula kanye ne-tablet. ; I-Lepidolite, eyaziwa nangokuthi i-phosphomica, iyi-mineral raw material yokukhipha i-lithium, futhi i-sericite isetshenziswa kakhulu kunjoloba, amapulasitiki, i-metallurgy, izimonyo, njll.
Ukucubungula Ubuchwepheshe
Ukuhlomula nokuhlanzwa
Izindlela zokuzuza nezindlela zokuhlanza ze-mica ziyahlukahluka ngokuya ngemvelo kanye nohlobo lwayo. I-Flake mica ivamise ukusebenzisa ukuhlunga okwenziwa ngesandla, ukuzuza ukungqubuzana, ukuhlomula komumo, njll.; i-mica echotshoziwe ithatha ukuhlukaniswa komoya kanye nokuntanta, i-biotite ne-phlogopite ingasebenzisa ukuhlukaniswa kukazibuthe okuqinile, i-muscovite, i-lepidolite ne-sericite iqukethe izici ezibuthakathaka kazibuthe. Ukungcola kungabuye kususwe ngokuhlukana okunamandla kazibuthe.
01 Ukukhetha (ekhomba) ukukhetha
Ebusweni bezimayini noma inqwaba yensimbi emgodini, i-mica ehlukanisiwe ne-monomer ikhethiwe, futhi ngokuvamile ifaneleka i-flake mica enkulu.
02 Ukuzuza kwe-Friction
Ngokomehluko phakathi kwe-coefficient ye-sliding friction ye-crystal mica flaky kanye ne-rolling friction coefficient ye-ganggue eyindilinga, i-mica crystal ne-ganggue kuyahlukaniswa. Enye yezinto ezisetshenziswayo i-slant plate sorter.
03 Ukuhlomula komumo
Ngokwezimo ezihlukene zamakristalu e-mica ne-ganggue, ikhono lokudlula igebe lesisefo noma imbobo yesisefo ngesikhathi sokusefa lihlukile, ukuze kuhlukaniswe i-mica ne-ganggue.
04 Ukukhetha umoya
Ngemva kokuba isihlabathi namatshe kuchotshoziwe, i-mica ngokuyisisekelo isesimweni sama-flakes, kuyilapho amaminerali e-ganggue asesimweni sezinhlayiya ezinkulu. Ngemuva kokuhlukaniswa kwamazinga amaningi, imishini ekhethekile isetshenziselwa ukuhlukaniswa komoya ngokomehluko wesivinini sokumiswa ekugelezeni komoya.
05 Ukuntanta
Njengamanje, kunezinqubo ezimbili zokuntanta: enye iwukuntanta kwe-mica nabaqoqi be-amine endaweni ene-asidi; enye iwukuntanta nabaqoqi be-anionic endaweni ene-alkaline, edinga ukuncishiswa ngaphambi kokukhethwa, futhi idinga ukukhethwa izikhathi eziningi.
06 Ukwehlukana kwamagnetic
I-Biotite ne-phlogopite zinezakhiwo ezibuthakathaka kazibuthe futhi zingakhethwa ngendlela enamandla kazibuthe; i-iron oxide kanye nokungcola kwe-iron silicate kuvame ukuhlotshaniswa ne-muscovite, i-sericite ne-lepidolite, engasuswa futhi ngokuhlukana okunamandla kazibuthe. Imishini yokuhlukanisa kazibuthe ikakhulukazi ihlanganisa amarola kazibuthe omile namanzi, izihlukanisi zikazibuthe zamapuleti kanye nezihlukanisi eziqondile zeringithoni eziphakeme ezinozibuthe.
Susa ikhasi
Ukucwecwa kwe-mica eluhlaza kube amashidi e-mica ezicaciswe ezihlukahlukene kubizwa ngokuthi i-mica peeling. Njengamanje, kunezindlela ezintathu zokucwecwa, okungezamanuwali, okomshini nokomzimba kanye namakhemikhali, ezisetshenziselwa ukucubungula njengamashidi aminyene, amashidi amancane, kanye ne-tube mica.
Ukugaya okuhle futhi okuphezulu kakhulu
Kunezinhlobo ezimbili zokukhiqizwa kokugaya okuhle kanye nokugaya kwe-ultra-fine kwe-mica, indlela eyomile kanye nendlela emanzi. Ngaphezu kwemishini yokuchoboza nokugaya, indlela eyomile nayo idinga ukuhlonyiswa ngemishini efana nokuhlola nokuhlukanisa umoya. Ukukhiqizwa okumanzi kusebenzisa imishini yokugaya emanzi ehlukahlukene, futhi ubuchwepheshe bokugaya obumanzi buyindlela eyinhloko yokuthuthukiswa ekukhiqizeni i-mica powder emihle.
Ukulungiswa kobuso
Ukuguqulwa kwendawo ye-mica powder kungahlukaniswa ngezinqubo ezimbili: ukuguqulwa kwe-organic surface kanye nokuguqulwa kwe-inorganic surface coating. Umkhiqizo we-mica oguquliwe ungathuthukisa amandla okusebenza wento, wehlise izinga lokuncipha lokubumba, umphumela omuhle wokubonwayo futhi uthuthukise inani lesicelo, njll.
