Ngesipiliyoni seminyaka engu-40 ezintweni eziphikisayo, uDkt. Guo Zongqi waya eShandong Hengjia High Purity ukuze aqondise inqubo yokuhlanzwa kwezinto ze-magnesium.

Emkhakheni we-refractory wase-China, igama likaDkt. Guo Zongqi belilokhu lixhunyaniswe nokuqanjwa kabusha kwezobuchwepheshe. Njengochwepheshe oyinhloko we-Jiachen Group kanye noprofesa ovelele we-Xi'an University of Architecture and Technology, wafunda ngaphansi kwabaholi bezimboni eminyakeni yakhe yokuqala futhi wabeka isisekelo socwaningo lwesayensi e-Luoyang Refractory Materials Research Institute. Kamuva, wasebenzela izikhondlakhondla zamazwe ngamazwe ezifana ne-RHI kanye ne-AIR, waba ngomunye wochwepheshe abambalwa abahlangene abanakho kokubili ukuzuzwa kwezemfundo kanye nesipiliyoni sokuzijwayeza kwezimboni. Muva nje, uDkt. Guo uvakashele i-Shandong Hengjia High Purity Aluminium Technology Co., Ltd. ukuze anikeze isiqondiso sobuchwepheshe ngenqubo yokuhlanza i-flotation ye-high-purity magnesia (MgO>98%). Ukuqoqwa kwakhe okujulile kwethiyori kanye nolwazi olusebenzayo kuphinde kwafaka umfutho omusha embonini.

Emshadweni wokukhiqiza we-Hengjia High Purity Aluminium, uDkt. Guo ugxile enqubweni yokucebisa i-flotation ye-magnesite. Ngokusho kwedatha yasensimini (njengoba kuboniswe kuThebula 1), isivuno sokugxila kwe-magnesium ngemva kokuntanta sifinyelele ku-75%, okuqukethwe kwe-MgO ngemva kokubala kwakuqinile ngaphezu kuka-98%, futhi okuqukethwe kokungcola okufana ne-SiO₂ ne-CaO kwehliswe kakhulu (konke <0.5%). Le mpumelelo idalwe "i-multi-stage gradient flotation" isixazululo esihlongozwe nguDkt. Guo:

:Hlaziya ngokunembile izigaba zamaminerali ezihlotshaniswayo njenge-talc ne-dolomite ku-ore ngokusebenzisa i-X-ray diffraction (XRD) ukuze kuthuthukiswe ukusatshalaliswa kosayizi wezinhlayiyana ezichotshozwayo;

: Sebenzisa ama-composite inhibitors (njenge-sodium hexametaphosphate) ukuze ukhethe ngokukhetha ukungcola kwe-silicate futhi uthuthukise ukusebenza kahle kokunothisa kwe-MgO;

:Kutuswa ukusebenzisa ijika lokubala eliguqukayo ukuze ugweme ukukhubazeka kwe-lattice ye-MgO futhi uqinisekise ukuminyana okuphezulu komkhiqizo wokugcina.

UDkt. Guo waveza ngokuqondile: "I-bottleneck ye-magnesia refractory materials yaseShayina akuzona izinqolobane, kodwa ukucwengwa kwenqubo yokuhlanza. Umkhuba ka-Hengjia uqinisekisile ukuthi kungenzeka yini ubuchwepheshe obuhlanganisiwe be-flotation-calcination ukuze kuphulwe ukubusa kwamazwe ngamazwe kwe-high-purity magnesia."

Umsebenzi kaDkt. Guo Zongqi uyi-microcosm yenguquko ye-refractory yase-China isuka “ekulandeleni” iye “ekugijimeni ngakunye”. Ngenkathi efundela iziqu zakhe zobudokotela eNyuvesi yaseMontreal, wafunda ngokuhlelekile indlela yokuguguleka kwezindawo zokulungisa i-manganese ezisetshenziswa ezithandweni zokushisa i-slag, waba omunye wamavulandlela kulo mkhakha. Ngesikhathi esebenza e-RHI, wahola ukuthuthukiswa kwezitini ze-magnesia-carbon eziboshwe nge-resin, ezaxazulula iphuzu lobuhlungu bempilo ye-converter emfushane yokuphila. Ngesikhathi evakashele e-Hengjia High Purity Aluminium, waphinde wagcizelela: "Umncintiswano wesikhathi esizayo ezintweni eziphikisayo kuzoba ukuncintisana okumbaxambili kocwaningo oluyisisekelo namandla obunjiniyela. Amabhizinisi adinga ukwakha iketango le-R&D 'eligxile ezinkingeni' namanyuvesi."

Ngaphezu kokuhlolwa kobuchwepheshe, uMnu. Shao, umphathi jikelele we-Shandong Hengjia High Purity Aluminium Technology Co., Ltd., kanye noDkt. Guo Zongqi babe nengxoxo ejulile mayelana nendlela emisha kanye nokuthuthukiswa kwezimboni zezinto eziphikisayo ezihlanzeke kakhulu.

UMnu. Shao uqale wethula kuDkt. Guo ukuhlelwa kwesu le-Hengjia High Purity emkhakheni we-alumina ehlanzekile kakhulu, i-magnesia nezinye izinto zokusetshenziswa ezikhethekile eziphikisayo eminyakeni yamuva, futhi wagcizelela ukuhlola kwenkampani ubuchwepheshe bokulungiselela obuluhlaza kanye nekhabhoni ephansi. Uthe: "Isidingo samanje semakethe yamazwe ngamazwe sezinto eziphikisayo ezihlanzekile kakhulu siya ngokuya silungiswa. U-Hengjia uthemba ukuqeda isimo semikhiqizo esezingeni eliphezulu ethembele ekuthengisweni kwamanye amazwe ngokusebenzisa emisha yezobuchwepheshe."

UDkt. Guo wavumelana ngokujulile nalokhu, futhi ngokusekelwe kokuhlangenwe nakho kwakhe, waveza: "Ukuncintisana okuyinhloko kwezinto ezihlanzekile kakhulu kusesiqinisekweni esikabili 'sobumsulwa' 'nokusimama'." Wabelane ngokukhethekile ngemiqondo ethuthukisiwe yezinkampani zaseYurophu ekulawuleni okunembile ukungcola nokuklanywa kwesakhiwo esincane, futhi waphakamisa ukuthi i-Hengjia High Purity iqhubeke nokuqinisa uhlelo olugcwele lwe-R&D "lokuhlola okuyisisekelo kocwaningo-inqubo yokwenza ngcono-uhlelo lokusebenza".

Lezi zinhlangothi zombili ziphinde zaxoxa ngemodeli yokubambisana yocwaningo lwemboni-inyuvesi. UDkt Guo wathatha ilabhorethri ehlanganyelwe ye-Xi'an University of Architecture and Technology kanye namabhizinisi njengesibonelo, egcizelela ukubaluleka "kocwaningo oluhlosiwe nentuthuko": "Ucwaningo lwemishini yamanyuvesi lunganikeza ukusekelwa kwethiyori kwenqubo yebhizinisi nokwenza kahle, futhi umkhuba wobunjiniyela wamabhizinisi ungabuyisela ukubaluleka kwangempela kocwaningo lwezemfundo." UMnu. Shao uphendule kahle kulokhu futhi wathi esikhathini esizayo, uzoqinisa ukuxhumana namanyuvesi kanye nezikhungo zocwaningo ukuze akhuthaze ngokuhlanganyela inqubo yokwenziwa kwasendaweni kwezinto eziphikisayo ezihlanzekile.

Lokhu kushintshana akugcini nje ngokujulisa ukuvumelana phakathi kwalezi zinhlangothi zombili ezingeni lobuchwepheshe, kodwa kuphinde kwaveza ipulani emisha ehlanganyelwe "yobuholi bezemfundo nokuqaliswa kwezimboni", okuhlinzeka ngemibono emisha yokuthuthukiswa kwekhwalithi ephezulu yezinto zaseShayina eziphikisayo.
