Kwimisebenzi emininzi yemizi-mveliso eshushu kakhulu, izinto zokugquma zidlala indima ebalulekileyo njengezikhongozeli ezibalulekileyo zokubamba nokufudumeza izinto.Izixhobo zokusika ze-ceramic ze-silicon carbide, ngenxa yokusebenza kwazo okugqwesileyo, kancinci kancinci ziba lukhetho olukhethwayo kumashishini ahlukeneyo.
1. Yintoni i-silicon carbide ceramic crucible
I-Silicon carbide ceramic crucible sisikhongozeli esimile okwesitya esinzulu esenziwe ngezinto ze-silicon carbide ceramic. I-Silicon carbide yikhompawundi enezibopho eziqinileyo ze-covalent, kwaye i-chemical bonding yayo ekhethekileyo inika ii-crucibles iimpawu ezininzi ezintle. Xa kuthelekiswa nezinto zeglasi eziqhelekileyo, ii-silicon carbide ceramic crucibles zinokumelana namaqondo obushushu aphezulu kwaye zizixhobo ezifanelekileyo zokusebenza kokufudumeza kumaqondo obushushu aphezulu.
2, Iingenelo zeSilicon Carbide Ceramic Crucibles
1. Ukumelana okugqwesileyo nobushushu obuphezulu: Ii-crucibles ze-ceramic ze-silicon carbide zinokumelana nobushushu obufikelela kwi-1350 ℃. Amandla ezixhobo eziqhelekileyo ze-ceramic aya kuncipha kakhulu kwi-1200 ℃, ngelixa amandla okugoba e-silicon carbide asenokugcinwa kwinqanaba eliphezulu kwi-1350 ℃. Olu phawu luyenza isebenze kakuhle kwiinkqubo zokunyibilikisa, ukutshisa kunye nezinye izinto ezishushu, ibonelela ngendawo ezinzileyo yobushushu obuphezulu bezixhobo kunye nokuqinisekisa inkqubela phambili egudileyo yenkqubo.
2. Ukumelana kakuhle ne-oxidation: Ii-crucibles ze-silicon carbide ceramic zinokugcina ukumelana okuhle ne-oxidation kwiindawo ezinobushushu obuphezulu. Ngokunyuka komxholo we-silicon carbide, ukumelana ne-oxidation kwe-crucible kuphucuka ngakumbi. Oku kuthetha ukuba ayifakwanga lula kwaye yonakale ngexesha lokusetyenziswa ixesha elide kobushushu obuphezulu, nto leyo eyandisa kakhulu ubomi bayo benkonzo, inciphisa ukuphindaphinda kokutshintshwa kwe-crucible, kwaye inciphisa iindleko zemveliso.
3. Uzinzo olugqwesileyo lweekhemikhali: Iiseramikhi zeSilicon carbide ziyamelana ngakumbi nezisombululo ezirhabaxa. Kwimizi-mveliso equka izinto ezahlukeneyo zeekhemikhali ezifana ne-metallurgy kunye nobunjineli beekhemikhali, ayisabelani nezinto zeekhemikhali edibana nazo, ngaloo ndlela iqinisekisa ubunyulu bezinto ezinyibilikisiweyo okanye ezisabelayo, iphephe ukungeniswa kokungcola, kwaye iphucula umgangatho wemveliso.
4. Ubunzima obuphezulu kunye nokumelana nokuguguleka: I-silicon carbide inobunzima obuphezulu, nto leyo eyenza ukuba i-crucible eyenziweyo ibe nokumelana nokuguguleka okuhle kwaye inokumelana nokuguguleka ngokomzimba kumaqondo obushushu aphezulu. Ngexesha lokusetyenziswa ixesha elide, inokugcina ubume bayo buqinile kwaye ayiguguleki okanye iguqulwe lula, nto leyo eqinisekisa ukusebenza kwayo kunye nobomi bayo benkonzo.
3, amasimi esicelo se-silicon carbide ceramic crucibles
1. Ishishini lesinyithi: Nokuba kukucocwa kweentsimbi zesinyithi ezifana nentsimbi, okanye ukunyibilika kweentsimbi ezingezizo zesinyithi kunye nee-alloys zazo ezifana nekopolo, i-aluminium, i-zinc, njl.njl., ii-silicon carbide ceramic crucibles zidlala indima ebalulekileyo. Zingamelana nokukhukuliseka kolwelo lwesinyithi olushushu kakhulu, ziqinisekise inkqubela ethe tye yenkqubo yokunyibilika kwesinyithi, ngelixa ziqinisekisa ubunyulu besinyithi kwaye ziphucula umgangatho weemveliso zesinyithi.
2. Ishishini leekhemikhali: lisetyenziselwa iimpembelelo zeekhemikhali ezishushu kakhulu kunye nonyango lwe-corrosive media. Ngenxa yokuzinza kwayo okugqwesileyo kweekhemikhali kunye nokumelana nobushushu obuphezulu, ingasebenza ngokuzinzileyo xa ijongene nezinto ezahlukeneyo zeekhemikhali kunye neendawo zokusabela ezishushu kakhulu, iqinisekisa inkqubela phambili ethe tye yeempembelelo zeekhemikhali ngelixa ithintela i-crucible ngokwayo ekubeni yonakale kwaye yonakale.
3. I-oven yemizi-mveliso: isetyenziswa njengesikhongozeli sokufudumeza xa kubaswa izixhobo ezahlukeneyo zoshishino, njengezitena ezingatshiyo. Ngokusebenzisa umbane wayo ofanelekileyo kunye nokumelana nobushushu obuphezulu, inokudlulisa ubushushu ngokukhawuleza nangokulinganayo, iqinisekise umgangatho wokusetyenziswa kwezinto, kwaye iphucule ukusetyenziswa kwamandla ngokufanelekileyo.
Ii-crucibles ze-silicon carbide ceramic, ezinoluhlu lweenzuzo ezifana nokumelana nobushushu obuphezulu, ukumelana ne-oxidation, ukumelana nokuguguleka, kunye nokuzinza kweekhemikhali, zibonakalise ixabiso elikhulu lokusetyenziswa kumashishini amaninzi kwaye zizikhongozeli ezifanelekileyo kwicandelo lemizi-mveliso elinobushushu obuphezulu. Ngokuqhubeka nokuqhubela phambili kunye nobuchule obutsha, sikholelwa ukuba ii-crucibles ze-silicon carbide ceramic ziya kusetyenziswa kumacandelo amaninzi kwaye zinike inkxaso enamandla kuphuhliso lwamashishini ahlukeneyo.
