Emkhakheni wezinto eziphikisayo, i-corundum, njengento ebalulekile eluhlaza, isibe yinto esetshenziswa kabanzi embonini ye-refractory ngenxa yezakhiwo zayo ezinhle kakhulu zomzimba namakhemikhali. Lesi sihloko sizokwethula izici eziyisisekelo, izinhlelo zokusebenza ezibanzi, isimo semakethe, kanye nenqubo yokukhiqiza ye-corundum ngokuningiliziwe, futhi sigxile emshinini wokugaya we-corundum osebenza kahle kakhulu we-200-mesh ukuze uveze kuwe ukuthi uhola kanjani inkathi entsha yokugaya kahle.

I-Corundum iyigugu elakhiwe yi-crystallization ye-aluminium oxide. Ukuqina kwayo kungokwesibili ngemuva kwedayimane ne-cubic boron nitride, futhi ubulukhuni bayo be-Mohs bufinyelela ku-9. Igama le-corundum livela eNdiya. Ingxenye yayo eyinhloko i-Al₂O₃, futhi kunezinhlobonhlobo ezintathu: α-Al₂O₃、β-Al₂O₃、γ-Al₂O₃. Ngenxa yezakhiwo zayo ezinhle kakhulu zomzimba, i-corundum isetshenziswa kabanzi ezintweni zokugaya ezithuthukile, amawashi, izinto ezithwala imishini yokunemba, neminye imikhakha.

Ukusetshenziswa kwe-corundum

Uhla lokusetshenziswa kwe-corundum lubanzi kakhulu, luhlanganisa izinkambu eziningi zezimboni ezifana ne-metallurgy, imishini, imboni yamakhemikhali, i-electronics, izindiza, nokuvikela izwe. Ngenxa yokumelana kwayo nokushisa okuphezulu, ukumelana nokugqwala, namandla aphezulu, i-corundum isetshenziswa njenge-crucible kanye nomkhumbi wokuphonsa iminyango yensimbi eshelelayo, ukuncibilikisa izinsimbi eziyigugu ezingavamile, nama-alloys akhethekile; ezinhlelweni zamakhemikhali, i-corundum isetshenziswa njengemikhumbi ehlukahlukene yokusabela namapayipi kanye nezingxenye zepompo zamakhemikhali; emkhakheni wemishini, i-corundum isetshenziselwa ukwenza imimese, isikhunta, izinto ezivimbela izinhlamvu, njll. Ngaphezu kwalokho, imikhiqizo ye-corundum ebonakalayo ingasetshenziswa futhi ukwenza izibani nama-microwave fairings, futhi imikhiqizo ye-Na-b-Al₂O₃ yizinto ze-electrolyte zokwenza amabhethri e-sodium-sulfur.

Isimo Semakethe yaseCorundum

Eminyakeni yamuva nje, ngokuthuthuka kwesayensi nobuchwepheshe kanye nokuthuthuka okusheshayo kwezimboni, isidingo se-corundum siqhubekile nokukhula, futhi amathemba emakethe abanzi. I-China, i-India, ne-Brazil ingabakhiqizi abakhulu be-corundum emhlabeni, phakathi kwayo i-China engumkhiqizi omkhulu kunayo yonke emhlabeni futhi ethumela kwamanye amazwe i-corundum emhlophe. Imakethe ye-corundum iveza isimo sebhalansi eyisisekelo phakathi kokunikezwa kanye nesidingo, ikhwalithi yomkhiqizo ithuthuka ngokuqhubekayo kanye nezindawo zokufaka isicelo zikhula ngokuqhubekayo. Ikakhulukazi emikhakheni esezingeni eliphezulu njengokugaya nokunemba okuphezulu, ukusetshenziswa kwe-corundum kuya ngokuya kunwebeka.

Inqubo yokukhiqiza ye-corundum

Inqubo yokukhiqiza ye-corundum ihlanganisa izinyathelo eziningi ezifana nokulungiswa kwezinto, ukuncibilikisa, ukupholisa, i-crystallization kanye nokucubungula. Okokuqala, i-high-purity aluminium oxide powder iyahlolwa futhi yomiswe ukuze kuqinisekiswe ukufana nokuhlanzeka kwezinto zokusetshenziswa. Khona-ke, i-aluminium oxide powder ifakwa esithandweni sikagesi futhi ishiselwe ekushiseni okuphezulu ukuze inyibilikise ibe yisimo se-liquid. Esimeni esincibilikisiwe, ama-molecule e-aluminium oxide azihlela kabusha ukuze akhe isakhiwo sekristalu futhi akhe izinhlayiya ze-corundum. Khona-ke, izinga lokushisa liyehliswa kancane kancane ukuze izinhlayiya ze-corundum ziqine kancane kancane zibe okuqinile. Okokugcina, kushisa futhi ukwenza isakhiwo se-crystal sizinze futhi sithuthukise ubulukhuni nokugqoka ukumelana kwe-corundum.

Ukwethulwa komshini wokugaya we-200 mesh corundum osebenza kahle kakhulu

Uma i-corundum isetshenziswa emikhakheni ethile, idinga ukugaywa ibe yimpushana ecolekile engu-200-mesh kuqala, njengama-abrasives ensimbi, izinto ze-ceramic zengilazi, nezinto ezibonakalayo ze-semiconductor. Isinyathelo sokuqala ngokuvamile ukugaya. Ngalesi sikhathi, udinga ukusebenzisa umshini wokugaya we-corundum osebenza kahle kakhulu we-200-mesh. I-Guilin Hongcheng iyimishini yokugaya esezingeni eliphezulu ye-R&D kanye nebhizinisi lokukhiqiza. I-HC series pendulum mill eyakhiwe iyinketho efanelekile yomshini wokugaya we-corundum osebenza kahle kakhulu we-200-mesh.

Izigayo ze-HC series swing zitholakala ngamamodeli ahlukahlukene, anemiphumela yehora esukela ku-1 ton to 50 tons. Izinto ezisetshenziswayo zizinzile uma ziqalwa, uhlelo lwengcindezi olungeluhle luvalwa kahle, indawo yokusebenzela ihlanzekile futhi icocekile, ukugcinwa kwansuku zonke kulula, kanti izindleko zokusebenza nezokulungisa ziphansi. Isetshenziswa kabanzi embonini ye-refractory futhi inokusebenza okucebile.

I-Guilin Hongcheng 200 mesh corundum high-efficiency umshini wokugaya kancane kancane iba imishini ebalulekile emkhakheni wokucubungula amaminerali kanye nokulungiswa kwezinto ezibonakalayo ngenxa yokusebenza kwayo okuphezulu, ukonga amandla nokuvikelwa kwemvelo. Njengempahla yokugaya yekhwalithi ephezulu, isidingo semakethe se-corundum siyaqhubeka nokukhula futhi amathemba emakethe abanzi. Siyakwamukela ukuthi usithinte ukuze uthole ikhotheshini yakamuva.
