Kwintsimi yezinto eziphikisayo, i-corundum, njengento ebalulekileyo ekrwada, ibe yinto esetyenziswa ngokubanzi kwishishini elichasayo ngenxa yezinto ezibalaseleyo zomzimba kunye neekhemikhali. Eli nqaku liza kwazisa iimpawu ezisisiseko, izicelo ezibanzi, isimo semarike, kunye nenkqubo yokuvelisa i-corundum ngokweenkcukacha, kwaye ugxininise kumatshini wokugaya we-200-mesh corundum ophezulu ukutyhila kuwe indlela ekhokelela ngayo ixesha elitsha lokugaya ngokufanelekileyo.

I-Corundum yinto enqabileyo eyenziwe yi-crystallization ye-aluminium oxide. Ukuqina kwayo okwesibini kuphela kwidayimane kunye ne-cubic boron nitride, kwaye ubunzima bayo be-Mohs bufikelela kwi-9. Igama le-corundum livela eIndiya. Icandelo layo eliphambili yi-Al₂O₃, kwaye kukho iintlobo ezintathu: α-Al₂O₃、β-Al₂O₃、γ-Al₂O₃. Ngenxa yeempawu zayo ezibalaseleyo zomzimba, i-corundum isetyenziswa ngokubanzi kwizinto eziphambili zokugaya, iiwotshi, izinto ezithwala izinto zoomatshini abachanekileyo, kunye namanye amacandelo.

Ukusetyenziswa kwecorundum

Uluhlu lwesicelo se-corundum lubanzi kakhulu, lubandakanya iindawo ezininzi zemizi-mveliso ezifana nesinyithi, oomatshini, imboni yeekhemikhali, i-electronics, i-aviation, kunye nokukhusela ilizwe. Ngenxa yokumelana nobushushu obuphezulu, ukumelana nokugqwala, kunye namandla aphezulu, i-corundum isetyenziselwa i-crucible kunye nesitya sokuphosa iingcango zetsimbi ezityibilikayo, ukunyibilikisa isinyithi esinqabileyo esinqabileyo, kunye ne-alloys ekhethekileyo; kwiinkqubo zeekhemikhali, i-corundum isetyenziswe njengeenqanawa ezahlukeneyo zokusabela kunye nemibhobho kunye neengxenye zempompo yeekhemikhali; kwintsimi yomatshini, i-corundum isetyenziselwa ukwenza iimela, i-molds, izinto ze-bulletproof, njl. Ukongeza, iimveliso ze-corundum ezicacileyo zingasetyenziselwa ukwenza izibane kunye ne-microwave fairings, kunye neemveliso ze-Na-b-Al₂O₃ zizinto ze-electrolyte zokwenza iibhetri ze-sodium-sulfur.

Imeko yeMarike yaseCorundum

Kwiminyaka yakutshanje, kunye nenkqubela phambili yesayensi kunye neteknoloji kunye nophuhliso olukhawulezayo lweshishini, imfuno ye-corundum iye yaqhubeka ikhula, kwaye amathemba emarike abanzi. I-China, i-Indiya, kunye ne-Brazil zingabavelisi abakhulu be-corundum ehlabathini, phakathi kwayo i-China ingumvelisi omkhulu wehlabathi kunye nomthengisi we-white corundum. Imarike yecorundum inika imeko yolungelelwaniso olusisiseko phakathi konikezelo kunye nemfuno, kunye nomgangatho wemveliso oqhubekayo uphucula kunye neendawo zesicelo eziqhubekayo zanda. Ngokukodwa kwiinkalo eziphakamileyo ezifana nokuchaneka okuphezulu kunye nokupholisa, ukusetyenziswa kwe-corundum kuya kuba kuninzi.

Inkqubo yokuvelisa i-corundum

Inkqubo yokuvelisa i-corundum iquka amanyathelo amaninzi afana nokulungiswa kwezinto, ukunyibilika, ukupholisa, i-crystallization kunye nokucubungula. Okokuqala, i-high-purity aluminium oxide powder ihlolwe kwaye yomiswe ukuze kuqinisekiswe ukufana kunye nokucoceka kwezinto eziluhlaza. Emva koko, i-aluminium oxide powder ifakwe kwisithando sombane kwaye ifudunyezwe kwiqondo lokushisa eliphezulu ukuze inyibilike ibe yimeko engamanzi. Kwimeko etyhidiweyo, iimolekyuli ze-aluminium oxide zilungelelanisa kwakhona ukuze zenze i-crystal structure kwaye zenze iincinci ze-corundum. Emva koko, iqondo lokushisa liyancipha ngokukhawuleza ukwenzela ukuba iinqununu ze-corundum ziqiniswe ngokuthe ngcembe zibe yinto eqinile. Ekugqibeleni, kushushu kwakhona ukwenza isakhiwo se-crystal sizinzile kwaye siphucule ubunzima kunye nokugqoka ukuchasana kwe-corundum.

Ukwaziswa kwe-200 ye-mesh corundum umatshini wokugaya ophezulu osebenzayo

Xa i-corundum isetyenziswa kwimimandla ethile, kufuneka igaywe ibe ngumgubo ocolekileyo we-200-mesh kuqala, ezifana ne-abrasives yentsimbi, izinto ze-ceramic zeglasi, kunye ne-semiconductor optical materials. Inyathelo lokuqala lidla ngokusila. Ngeli xesha, kufuneka usebenzise umatshini wokugaya we-corundum we-200-mesh ephezulu. UGuilin Hongcheng lishishini eliphambili lasekhaya eliphambili lokusila iR&D kunye neshishini lokuvelisa. I-HC series pendulum mill iphuhliswe yinto efanelekileyo yomshini wokusila we-200-mesh corundum ophezulu.

I-HC series swing Mills ziyafumaneka kwiimodeli ezahlukeneyo, ezineziphumo zeyure ukusuka kwi-1 toni ukuya kwiitoni ezingama-50. Isixhobo sizinzile xa siqaliswa, inkqubo yoxinzelelo olubi inokutywinwa kakuhle, indawo yokusebenzela icocekile kwaye icocekile, ukugcinwa kwemihla ngemihla kulungele, kwaye iindleko zokusebenza kunye nokugcinwa ziphantsi. Isetyenziswa ngokubanzi kwishishini le-refractory kwaye inomsebenzi otyebileyo.

I-Guilin Hongcheng i-200 mesh corundum umatshini wokugaya ophezulu ngokuthe ngcembe uba sisixhobo esibalulekileyo kwintsimi yokulungiswa kwezimbiwa kunye nokulungiswa kwezinto ngenxa yokusebenza kwayo okuphezulu, ukonga amandla kunye nokukhuselwa kwendalo. Njengomgangatho ophezulu wezinto zokugaya, imfuno yemarike ye-corundum iyaqhubeka ikhula kwaye amathemba emarike abanzi. Wamkelekile ukuba uqhagamshelane nathi malunga nekowuti yamva nje.
