Ngaba ukuphawula kucima ingcaciso yemathiriyeli yokucoca ekhethiweyo kuyachaphazela?
Ixesha:10-27-2020
Iizixhobo zokususa uphawu lwendlelaikhethwe ngokungafanelekanga ngenxa yokhetho olungafanelekanga lwebhedi yohluzo olunemigangatho emithathu echaphazela iinkcukacha ezikhethiweyo zemathiriyeli yokucoca.I-FeTiO3 yenze ukuxhathisa kweasidi kunye nealkali yesixhobo sokucoca uphawu lwe-RZG ye-brand magnetite ephezulu kakhulu kuneso semagnetite eqhelekileyo.Nangona kunjalo, olu hlobo lwesihluzi, isanti ye-garnet engenathuli ye-RZG esetyenzisiweyo ngokuhambelana nemigangatho ephezulu yomgangatho, inesantya sokuzinzisa ngokukhawuleza, kwaye ngenxa yokuba umaleko osezantsi wezinto zokucoca unobungakanani obuncinci, unamandla okuthintela ukunqunyanyiswa. izinto eziqinileyo ukusuka ekungeneni.Ukumakishwa kukucoca.Intsimbi eqhelekileyo iya kuhamba ngenkqubo yokuqhunyiswa kwesanti kunye nokususwa komhlwa phambi kokusetyenziswa.Ubuninzi 4. Ubunzima bomhlaba bunokufikelela kwi-30-80 microns.Enyanisweni, ukucocwa kokumakisha kusetyenziswa njenge-sandblasting abrasive engenathuli.Ngenxa yobunzima obukhethekileyo begarnet, ngokuqhelekileyo yenziwe ngesanti yequartz ye-anthracite kunye nemagnetite (okanye igarnet).Ngokuqhelekileyo, i-RZG engenathuli i-garnet ye-sandblasting abrasive (i-mery yendalo) ingasetyenziswa.Iindleko zokuqhushumba kwesanti ziphantsi.Nciphisa ngakumbi iindleko zokusetyenziswa komthengi.
1. Ngombulelo kukuqina okugqwesileyo kunye nokuqina okuphantsi kwe-RZG garnet ye-sandblasting abrasive, ukuxuba umaleko kuya kwenzeka kwisiza emva kokuhlanjwa ngesicoci somgca wokumakisha umva.Iinzuzo zobugcisa kunye nezoqoqosho eziziswa kukususwa kwemigca yokumakisha zivelele ngakumbi, kwaye ithathe indawo ye-ballast yentsimbi yokuqala (ore copper), isanti yomlambo kunye nesanti yequartz.Ukumakisha ukucocwa kwandisa kakhulu ukunyanzeliswa kwezinto zokucoca i-magnetite, kunye ne-RZG yobunzima begarnet engenathuli 7. I-RZG i-garnet engenathuli ikhethwe kwi-iron-aluminium garnet rock ore ephezulu, i-garnet-free garnet sandblasting I-abrasive ayinayo kuphela iimpawu zomgangatho ophezulu kunye nexabiso eliphantsi, akukho protrusions ezingathandekiyo kunye nemigodi, isanti ye-garnet ye-RZG engenathuli ingangena nzulu kwimingxuma kunye neendawo ezingalinganiyo zokucoca, kodwa iqulethe izithako ze-Al2O3 ezinenzuzo.Emva kokuhlamba okuninzi kwinkqubo yokuvelisa, akunakwenzeka ukufezekisa ukungaxutywa ngokupheleleyo emva kokuhambelana ne-iso backwash.
2. Umatshini wokucoca wokumakisha unokuphinda uphephe i-silicosis ebangelwa yi-silicon yamahhala kwaye ufumane ngokulula ibakala eliphezulu le-sandblasting ye-Sa3.Itekhnoloji yokucoca yokucocwa kokumakisha yanamhlanje ihlaziywa rhoqo.Phakathi kwabo, uphando lwemithombo yeendaba zokucoca ezinomaleko amathathu kunye nokukhuthazwa kweziphumo zayo kuzise inzuzo ebalaseleyo yobugcisa nezoqoqosho kwimveliso.Ngoko ke, isetyenziswe ngokubanzi kwizangqa zokunyanga amanzi asekhaya nakwamanye amazwe.Qwalasela.Kodwa ngolu hlobo lokucoca, indlela yokukhetha izinto zokucoca kunye nendlela yokuyibeka?Njengoko igama lisitsho, ibhedi yokucoca isihluzi esinemigangatho emithathu yenziwe ngamaleko amathathu esixhobo sokucoca.Esi sihluzo sinomthamo omkhulu wokucanda ubumdaka, isakhono esinamandla sokuthintela izinto eziqinileyo ukuba zingangeni, isantya esiphezulu esivumelekileyo sokuhluza, umgangatho olungileyo wamanzi, kunye nomjikelo omde wokucoca.Ibhedi yesihluzi sesihluzi esinemigangatho emithathu sikholisa ukwenziwa ngeanthracite, isanti yequartz kunye nemagnetite (okanye igarnet).
3. Izinto zokucoca ezinobungakanani besuntswana elikhulu kunye nobunzima obuthile obuthile busasazwa kumaleko aphezulu, izinto zokucoca ezinobungakanani besuntswana eliphakathi kunye nobunzima obuthile busasazwa embindini, kunye nezinto zokucoca ezinobungakanani bamasuntswana amancinci kunye nomxhuzulane omkhulu okhethekileyo. isasazwe kumaleko asezantsi.Oko kukuthi, i-avareji yobungakanani bamasuntswana ezinto ezithathu zokucoca ngokuthe ngcembe ziyancipha ukusuka phezulu ukuya ezantsi.Ngale ndlela, umthamo wokuvalela ugutyulo lwebhedi yokucoca unokusetyenziswa ngokupheleleyo, ngoko ke umjikelo wokucoca mde, kwaye ngenxa yokuba owona mgangatho usezantsi wemathiriyeli yokucoca unobungakanani bamasuntswana amancinane, ulungelelana ngakumbi ne-turbidity ephezulu okanye ukuguquguquka okukhulu kwe-turbidity.Xa uyila iinkcukacha zebhedi yokucoca, ungabhekisela kumava aphumelele kwezinye iindawo.Ukongeza, kufuneka iqinisekiswe kwaye ihlengahlengiswe ngokuvavanywa ngokweemeko zendawo, kwaye akufanele isetyenziswe ngoomatshini.Ngenxa yokukhetha okungafanelekanga kwebhedi yokucoca ibhedi emithathu echaphazela ukucaciswa kwezinto ezikhethiweyo zokucoca, ukuxutywa komgangatho kuya kwenzeka emva kokuba isixhobo sokucoca sokumakisha sigungxulwe.
4. Ngenxa yezinto ezingcolileyo zokucoca, ukuhamba kwamanzi aphazamisekileyo, kunye nobukhulu obuhlukeneyo be-particle kunye nobunzima obuthile besixhobo sokucoca, akunakwenzeka ukufezekisa umaleko ongaxutywanga ngokupheleleyo emva kokuhlamba umva.Ngeli xesha, ukhetho lwe-magnetite ye-high-density filter material njenge-litter ibaluleke kakhulu.Ukuba inkunkuma enobunzima obuthile obuncinci okanye obungafanelanga busetyenziswa, kulula ukubangela ukuba izinto zokucoca kunye nenkunkuma zibonakale zixutywe ngexesha lenkqubo yokuhlamba umva, kunye neRZG brand magnetic Izinto zokucoca intsimbi zikhethwa kuxinzelelo olunqabileyo lwe-ultra-high. ilitye le-metamorphic, elinomlinganiselo omkhulu, umxholo wesinyithi ophezulu, kwaye iqulethe i-Al2O3 enenzuzo.Ukucocwa kokumakisha kwandisa kakhulu ukuxhathisa ukunxiba kwesixhobo sokucoca imagnetite.Iukumakisha umenzi womatshini wokucoca's Ukuxhathisa ukunxitywa kwe RZG magnetite filter media yi 20 ~ 35% ephezulu kunolo lwesiqhelo lokucoca imagnethi media.Ngaxeshanye, i-FeTiO3 equlethwe (ekwachazwa njenge-FeOTiO2) kunye ne-FeTiO3 zenza i-asidi kunye nokumelana ne-alkali ye-RZG brand magnetite filter material ibe phezulu kakhulu kunemagnetite eqhelekileyo.
