Izitini ezivamile eziphikisayo:Uma ucabangela intengo kuphela, ungakhetha izitini ezivamile ezishibhile eziqinile, njengezitini zobumba. Lesi sitini sishibhile. Isitini sibiza cishe u-$0.5~0.7/ibhulokhi kuphela. Sinezinhlobo eziningi zokusetshenziswa. Kodwa-ke, ingabe sifanelekile ukusetshenziswa? Ngokuqondene nezidingo, uma singahlangatshezwanga, singabangela ukulungiswa njalo ngenxa yokuguga, futhi singase singakwazi ukusetshenziswa ngendlela evamile. Ukulungiswa okuphindaphindiwe kungaholela ekulungisweni kusenesikhathi ngisho nasekulimaleni kwemishini, okungafanele ukuzuzwa.
Izitini zobumba ziyizinto ezibuthakathaka kakhulu, ezinomzimba ongaba ngu-2.15g/cm3 kanye nokuqukethwe kwe-alumina okungu-≤45%. Nakuba ukuphikiswa kuphezulu njengo-1670-1750C, kusetshenziswa kakhulu ebangeni lokushisa eliphezulu elingu-1400C. Lo mkhiqizo ungasetshenziswa kuphela ngokuhambisana nezidingo. Izinga lokushisa, ezinye izingxenye ezingabalulekile, izinga lokushisa elijwayelekile lokucindezela izitini zobumba aliphezulu, yi-15-30MPa kuphela, lokhu kuhlobene nezinkomba zomkhiqizo, okuyisona sizathu esenza izitini zobumba zishibhile.
Izitini eziqinile ze-alumina:Izitini ze-alumina eziphakeme zinezigaba ezine ezisekelwe ku-alumina. Ngenxa yokuthi okuqukethwe kwe-aluminium kwezinto zokusetshenziswa kuphakeme kunokwezitini zobumba, igama elithi izitini ze-alumina eziphakeme livela kulokhu. Ngokusho kwesigaba, lo mkhiqizo ungasetshenziswa ebangeni lokushisa eliphezulu eliphakathi kuka-1420 no-1550°C. Uma usetshenziswa, ungavezwa emalangabini. Amandla okucindezela okushisa ajwayelekile aphezulu njengo-50-80MPa. Uma uvezwa emalangabini, izinga lokushisa lobuso alikwazi ukuba phezulu kunokushisa okusebenzayo. Lokhu kuthinteka kakhulu ubuningi bomkhiqizo kanye nokuqukethwe kwe-alumina.
Izitini eziningi:Izitini ezi-mullite eziphikisanayo zinamandla aphezulu okubamba futhi zisebenza kahle. Zitholakala ngezinhlobo ezisindayo nezilula. Izitini ezisindayo ze-mullite zifaka izitini ze-mullite ezihlanganisiwe kanye nezitini ze-mullite ezisikiwe. Ukumelana nokushaqeka kokushisa komkhiqizo kuhle; imikhiqizo elula inomphumela omuhle wokuvikela ukushisa. Imikhiqizo elula yile: JM23, JM25, JM26, JM27, JM28, JM30, JM32. Imikhiqizo yochungechunge lwe-mullite elula ingavezwa emalangabini, futhi ama-pores asatshalaliswa ngokulinganayo Ngokusho kokuqukethwe okunamandla adonsela phansi kanye nezinto zokusetshenziswa zomkhiqizo, i-JM23 ingasetshenziswa ngaphansi kwama-degrees angu-1260, i-JM26 ngaphansi kwama-degrees angu-1350, kanti i-JM30 ingasetshenziswa ebangeni lokushisa eliphakeme lama-degrees angu-1650. Lesi futhi yisona sizathu esenza izitini ze-mullite zibize kakhulu.
Isitini seCorundum:Isitini se-Corundum siyisitini esiphikisayo sezinga eliphezulu esinokuqukethwe kwe-alumina okungaphezu kuka-90%. Lo mkhiqizo unemikhiqizo ehlanganisiwe nehlanganisiwe. Ngokusho kwezinto zokusetshenziswa, imikhiqizo ifaka: isitini se-zirconium corundum esihlanganisiwe (AZS, isitini esihlanganisiwe), isitini se-chromium corundum, njll. Amandla okucindezela okushisa ajwayelekile makhulu kune-100MPa futhi angasetshenziswa isikhathi eside endaweni yokushisa ephezulu yama-degrees angu-1,700. Intengo yalesi sitini esiphikisayo iyahlukahluka kusuka ezinkulungwaneni eziningana kuya emashumini ezinkulungwane zama-yuan ngethani ngenxa yezici ezifana nenqubo yokukhiqiza kanye nokuqukethwe kwezinto zokusetshenziswa.
Izitini zebhola ezingenalutho ze-Alumina:Izitini zebhola le-alumina eziyize ziyizitini zokuvikela ezilula ezibizayo, ezibiza cishe ama-RMB ayi-10,000 ngethani. Ngenxa yezindawo ezahlukene zokusetshenziswa kanye nezinqubo zokukhiqiza, okuhlanganisa nokuqukethwe kwe-alumina, njll., intengo yomkhiqizo kufanele ibe phezulu. , njengoba kusho isisho, inani lemali.
Lokhu okungenhla kuyisingeniso sobuningi, ukumelana nokushisa okuphezulu kanye nentengo yezitini eziphikisayo. Ngokuvamile, ubukhulu bevolumu yezinto eziphikisayo kulinganiswa ngaphambi kokushiya ifektri. Ubuningi bevolumu: bubonisa isilinganiso sesisindo somkhiqizo owomile nevolumu yawo iyonke, evezwe ku-g/cm3.
