Gqoka Ulayini Ongazweli Wesikwele Wocekeceke

I-ceramic liner yesikwele ichazwa ngezinto ezine ezibalulekile:

Ukuqina: I-Mohs 9, imelana nokuklwebheka kusuka ku-quartz nama-ores amaningi. Insimbi ingu-Mohs 5–6 kuphela.

Ukuminyana: Ukuminyana kwenqwaba Kukhulu noma kulingana no-3.63 g/cm³, ukumuncwa kwamanzi Ngaphansi noma kulingana no-0.01% – akukho ukungena okuwuketshezi, akukho monakalo wokuqandisa{2}}.

Ukumelana nomthelela: Ukuqina kokuphuka kufika ku-5.70 MPa·m¹/² (ibanga le-TW92S), kunciphisa ukuqhekeka ngaphansi komthwalo osindayo.

Ukuguquguquka komumo: Itholakala njengamakhyubhu angenalutho, amabhlogo axhumene, amakhyubhu acijile, namadizayini anamaqhubu ayisiyingi noma izimbobo.

Impahla, Isakhiwo kanye Nokukhiqiza

I-ceramic liner eyisikwele yenziwe ngempushana ye-alumina ecwebile{0}ephezulu. Amabanga asukela ku-92% kuya ku-99% Al₂O₃, enobumsulwa obuphakeme obunikeza ukumelana nokugqokwa okukhulu kanye nengozi yokungcola ephansi. Impushana imanzi-igaywa ngosayizi wezinhlayiyana ezifanayo, bese ifutha-yomiswa. Ukwakha kusebenzisa ukucindezela okomile noma ukucindezela okubandayo kwe-isostatic (CIP) kuye ngosayizi wethayela. I-CIP iqinisekisa ukuminyana okufanayo kulo lonke i-cube, isusa izindawo ezibuthakathaka ezibangela ukuguga okungalingani. Ngemva kokwakhiwa, imizimba eluhlaza iyomiswa kancane ukuze kugwenywe{10}}imifantu, bese icwiliswa kuhhavini lomhubhe ngo-1500–1550 degree. Ngesikhathi sokucwiliswa, izinhlamvu ze-alumina ziyahlangana, zithole ukuminyana kwenqwaba ngaphezu kuka-3.63 g/cm³ kanye nokumuncwa kwamanzi ngaphansi kuka-0.01%. Iqoqo ngalinye lingaphansi kokulawulwa kwekhwalithi okuqinile: ukwakheka kwamakhemikhali okuqinisekiswe yi-XRF, ubulukhuni buhloliwe nge-ASTM C1327 ngayinye, nokuhlolwa kobukhulu obunamageji alinganisiwe. Amathayela anama-chips, ama-cracks, noma{19}angaphandle{20}kobukhulu bokubekezelela anqatshiwe.

Okwenza i-Tecera ihluke ukusetshenziswa kokucindezela kwe-isostatic kwawo wonke amakhyubhu amakhulu kuno-50 mm, kanye nezimo zangokwezifiso ezingaphezu kuka-2,000 - amakhyubhu aqoshiwe, amabhlogo axhumene, amakhyubhu anamaqhuqhuva ayindilinga,{3}nemiklamo{3}}emise okwefeni yezindawo ezigobile.

Izinzuzo Zomkhiqizo

Ngenxa yokuthi i-ceramic liner eyisikwele iminyene ngokugcwele ngokumuncwa kwamanzi Ngaphansi noma ilingana no-0.01%, alukho uketshezi lwenqubo olungena ku-ceramic - ama-slurries ane-asidi awakwazi ukuwenza buthaka, futhi isimo sezulu esibanda asikwazi ukuqhekeka. Ngenxa yokuthi ukuqina kwayo kwe-Mohs kungu-9, imelana nokuklwebheka ku-quartz{3}}insimbi ecebile nezinhlayiya eziqinile, ngokungafani nensimbi eguguleka ngokushesha. Ngenxa yokuthi i-Tecera inikeza amadizayini axhumene futhi acijile, ulayini ususa izikhala eziqondile{5}}eziba amashaneli okuguguleka - ushintsho olulula olungase lube kabili noma kathathu impilo yesevisi{6}}ezinhlelweni zokusebenza zesivinini esikhulu. Amalayini e-alumina mosaic anweba impilo yesevisi izikhathi ezingu-2-3 uma kuqhathaniswa nezinsimbi ezivamile zensimbi noma ze-polymer, athuthukisa ngokuqondile isikhathi nokunciphisa izindleko zokusebenza.

Izimo Zohlelo Lokusebenza

Izimayini: Ama-Chute liners, amabhokisi okuphakelayo kwesivunguvungu, izindawo zokudlulisa ama-conveyor. Imayini yethusi eNingizimu ye-Australia yacubungula insimbi engamathani angu-2,200 ngehora ngeshuthi yokudlulisa{3}}yesivinini esiphezulu. Amalayini angaphambili agqokile phakathi namaviki. Ngemva kokufaka amalayini e-ceramic ayisikwele, impilo yesevisi inwetshiwe yaba ngaphezu kwezinyanga eziyi-12.

Ukukhiqiza amandla: Amashubhu okuphakelayo amalahle, izimbobo zokubamba umlotha. Isistimu yokuthutha amalahle yesikhungo samandla ashisayo yayidinga ukunakekelwa izikhathi ezingu-2-3 ngenyanga. Ngemva kokufaka amalayini e-alumina ceramic, ukulungiswa kwehle kwaba kanye ngekota kanti izindleko zokusebenza zehle ngo-40%.

Usimende: Imigqomo yokudla okungaphekiwe, amashubhu e-clinker, amapayipi okukhipha isigayo. Isitshalo sikasimende saseBrazil sabona impilo ye-clinker chute isuka ezinyangeni eziyisi-8 iye ngaphezu kwezinyanga ezingama-28.-

Izigayo zensimbi: Izicucu zezitshalo ze-Sinter, ama-coke hopper, imigqomo yokuphakelayo yesithando somlilo. Amalayini e-ceramic ayisikwele amelana nezinga lokushisa eliphezulu (kufika ku-400 degree) nothuli lwe-sinter olubi.

Iya-oda

I-Tecera ihlinzeka ngo-92%, 95%, 97%, 99%, kanye namalayini e-ceramic ayisikwele e-ZTA ngobukhulu obusuka ku-6 mm ukuya ku-50 mm, ngendlela ecacile, ehlangene, kanye nezimo ezingokwezifiso. Amasampula wamahhala okuhlolwa okulimazayo. Isikhathi sokuhola 2-3 amaviki ajwayelekile, 4-6 amaviki ngokwezifiso. Ukuthunyelwa komhlaba wonke okunamaphakheji ebanga lokuthekelisa. Phendula phakathi kwezinsuku ezimbili zebhizinisi.

Amashadi ashisayo: gqoka umugqa oqinile wesikwele we-ceramic, ama-China agqoka abakhiqizi bomugqa wesikwele we-ceramic, abahlinzeki, imboni
