Kwiinkalo ezininzi zemveliso yemizi-mveliso, ukuguguleka kwezixhobo bekusoloko kuyinto ephambili echaphazela ukusebenza kakuhle kwemveliso kunye neendleko. Ukuze kusonjululwe le ngxaki, kuye kwavela izinto ezahlukeneyo ezingagugiyo, phakathi kwazo i-silicon carbide engagugiyo iye yaba “yeyona nto ithandwayo” kwicandelo lemizi-mveliso ngenxa yokusebenza kwayo okugqwesileyo. Namhlanje, makhe sijonge le nto imangalisayo.
1, Yintonii-silicon carbide engagugiyo?
I-silicon carbide (i-SiC) yi-compound eyenziwe yi-silicon kunye ne-carbon, enesakhiwo sekristale esikhethekileyo nesizinzileyo. Iiyunithi zayo ezisisiseko zesakhiwo zidibene ne-SiC kunye ne-CSi tetrahedra. I-silicon carbide engagugiyo yi-layer ekhuselayo eyenziwe ngezinto ze-silicon carbide ukukhusela ingaphakathi lezixhobo ekugugeni nasekukrazukeni. Ingenziwa ibe ziimo ezahlukeneyo, ezifana neeringi ze-ceramic, ii-ceramic liners, njl.njl., ize ifakwe kwiindonga zangaphakathi zezixhobo ezifana nemibhobho, imizimba yepompo, kunye nee-silos ezisengozini yokukhukuliseka kunye nokungqubana kwezinto.
2. Iingenelo ze-silicon carbide engagugiyo
1. Ubunzima obuphezulu kunye nokumelana nokuguguleka okukhulu: Ubunzima be-silicon carbide ceramics buphezulu kakhulu, bulandela idayimani enzima kakhulu. Obu bunzima buphezulu buyinika ukumelana nokuguguleka okukhulu, ikwazi ukumelana nokuguguleka okukhawulezayo kunye nokungqubana okunamandla kwezinto, nto leyo eyandisa kakhulu ubomi benkonzo yezixhobo, nto leyo eyenza ukuba ibe yinto efanelekileyo yokumelana nokuguguleka kwicandelo lokuguga okunzima. Xa kuthelekiswa nezinye izinto eziqhelekileyo ezimelana nokuguguleka, i-silicon carbide lining emelana nokuguguleka ineengenelo ezibalulekileyo ekumelaneni nokuguguleka, nto leyo enokunciphisa amaxesha okugcinwa nokutshintshwa kwezixhobo kumashishini kunye neendleko zemveliso eziphantsi.
2. Ubunzima obuphantsi kunye nobunzima obulula: I-silicon carbide inobunzima obuphantsi kakhulu kuneentsimbi ezifana nentsimbi. Umzekelo, ubuninzi beeseramikhi ze-silicon carbide ezisabelayo yi-3.0g/cm³ kuphela, ngelixa ubuninzi beeseramikhi ze-silicon carbide ezingenaxinzelelo yi-3.14-3.0g/cm³. Kwimeko yomthamo ofanayo, ubunzima be-lining engagugiyo ye-silicon carbide bulula, nto leyo engenzi nje ukuba kube lula ukuthuthwa nokufakwa, kodwa ikwanciphisa umthwalo woomatshini wezixhobo, okwenza ukusebenza kwezixhobo kube lula, kwaye kuvumela ukufakwa kwemibhobho nezinye izixhobo ukuba zibe phezulu nangakumbi.
3. Ukumelana nobushushu obuphezulu: Izinzile kakuhle kubushushu kwaye isakhiwo sekristale esikhethekileyo se-silicon carbide siyivumela ukuba imelane nobushushu obuphezulu, kunye nobushushu obutshisayo obufikelela kwi-1350 ℃. Olu phawu lwenza ukuba i-lining ye-silicon carbide engagugiyo ihlale isebenza kakuhle nakwiindawo ezinobushushu obuphezulu, ngaphandle kokuguquka okanye ukonakala ngenxa yobushushu obuphezulu, nto leyo eyenza ukuba ifaneleke kwiimeko ezahlukeneyo zoshishino ezinobushushu obuphezulu ezifana ne-metallurgy, umbane kunye neminye imimandla.
4. Ukumelana nokugqwala: I-silicon carbide ineempawu zeekhemikhali ezizinzileyo kwaye inokubonakalisa ukumelana nokugqwala okuhle xa ijongene nezinto ezahlukeneyo zeekhemikhali. Nokuba kuthuthwa kwezinto ezinamandla ze-acidic kunye ne-alkaline kwimveliso yeekhemikhali okanye kwicandelo lokukhusela okusingqongileyo njengonyango lwelindle, i-silicon carbide enganyangekiyo ingakhusela izixhobo ngokuthembekileyo, ithintele izixhobo ekubeni zigqwale zizinto zeekhemikhali, kwaye yandise ubomi benkonzo yezixhobo.
5. Ukuqhuba okubuthathaka kunye nokungaguquguquki: Iiseramikhi ze-silicon carbide zinokuqhuba okubuthathaka, nto leyo eyenza ukuba zifaneleke kwizicelo ezineemfuno ezingqongqo zombane ongaguqukiyo, njengeendawo zokusebenzela ezithintela ukuqhuma. Kwezi meko, umbane ongaguqukiyo unokubangela iingozi ezinkulu zokhuseleko, kwaye umsebenzi wokungaguquguquki we-silicon carbide engagugiyo unokuthintela ngempumelelo ukuqokelelwa kombane ongaguqukiyo kwaye uqinisekise ukhuseleko lwemveliso.
6. Kulula ukuyila, iyakwazi ukucubungula iindawo ezinkulu nezintsonkothileyo ezimile okwesi sixhobo: I-silicon carbide ingacutshungulwa kusetyenziswa iinkqubo ezifana nokusabela kokusila, nto leyo eyinika iingenelo ezinkulu ekubumbeni. Ngale nkqubo, ii-ceramics ezinkulu kunye nee-ceramics ezimile okwesi sixhobo ezintsonkothileyo zinokwenziwa. Oku kuthetha ukuba nokuba injani na indlela ekhethekileyo kunye nobukhulu bezixhobo, i-silicon carbide enganyangekiyo ingalungiswa kakuhle ukuze ihlangabezane neemfuno zezixhobo ezahlukeneyo zoshishino.
I-lining engagugiyo ye-silicon carbide ibonakalise ixabiso elikhulu kwicandelo lemizi-mveliso ngenxa yeenzuzo zayo ezininzi. Ngophuhliso oluqhubekayo kunye nenkqubela phambili yesayensi yezinto, kukholelwa ukuba i-lining engagugiyo ye-silicon carbide iya kusetyenziswa kwiindawo ezininzi, inika inkxaso enamandla yokusebenza ngokufanelekileyo nangokuzinzileyo kwemveliso yemizi-mveliso. Ukuba unomdla kwi-lining engagugiyo ye-silicon carbide, nceda uzive ukhululekile ukunxibelelana nathi nangaliphi na ixesha ukuze uphonononge iimfihlo ezingakumbi malunga neeseramikhi ze-silicon carbide kunye.
