Isihluzi segraphite, {0}njengesixhobo sokutywina esisebenza kakhulu, sisetyenziswa kakhulu kwimichiza, kwipetroleum, nakumashishini ombane. Inkqubo yokwakheka kwayo ichaphazela ngokuthe ngqo ubuninzi bezinto, ukuxhathisa ukubola, kunye namandla omatshini. Eli nqaku liza kuxubusha ngokubanzi inkqubo yokwenza i-graphite filler kunye neengongoma zayo eziphambili zobugcisa.
Iinkqubo zokwenza isigcwalisi se-graphite ngokuyintloko ziquka ukucinezela, ukukhupha, kunye noxinzelelo lokubumba. Ukubumba ukunyanzeliswa yeyona ndlela ixhaphakileyo, ilungele umgubo ocoliweyo okanye igrafu yegrafu imathiriyeli ekrwada. Le nkqubo isebenzisa i-hydraulic okanye i-mechanical press ukuxuba umgubo wegraphite kunye ne-binder uze uyicinezele kwimilo efunekayo phantsi kobushushu obuphezulu kunye noxinzelelo. Ngexesha lenkqubo yokucinezela, uxinzelelo olufanayo lubalulekile kuxinaniso kunye namandla emveliso yokugqibela. Uxinzelelo ngokuqhelekileyo lulawulwa phakathi kwe-10 kunye ne-30 ye-MPa, kwaye amaqondo obushushu agcinwa phakathi kwe-150 kunye ne-300℃ukukhuthaza ukuthambisa kunye nokudibanisa kwe-binder.
Ukubunjwa kwe-Extrusion kukulungele ukuveliswa okuqhubekayo kweentonga zegraphite okanye iibhubhu. Inkqubo ibandakanya ukuxuba izinto eziluhlaza, ukuxova, ukukhupha, kunye nokomisa. I-graphite powder kunye ne-binder (efana ne-phenolic resin okanye i-asphalt) ixutywe ngokucokisekileyo kwi-kneader ukwenza i-slurry yeplastiki efanayo. Olu daka luthi ke lukhutshelwe kwidayizi ukuya kumnqamlezo othile{3}}ukumila kwecandelo. Ukubunjwa kwe-Extrusion kufuna uyilo oluphezulu lokubumba ukuqinisekisa ukuhamba okufanayo kwe-slurry kunye nokuphepha iziphene zangaphakathi. Imveliso ebunjiweyo ifumana{6}}ubushushu obuphezulu calcination ukususa izinto eziguquguqukayo kwisibophelelo kunye nokuphucula igraphitization.
Ukubumba ukunyanzeliswa kulungele -izitywino zegraphite ezimile okwemilo, okufana neegaskets okanye ukupakishwa kwe-annular. Le nkqubo ibandakanya ukuxuba i-graphite powder kunye ne-binder kwisilinganiselo esifanelekileyo, ukuzalisa umxube kwi-mold yensimbi eshushu ngaphambili, kwaye emva koko usebenzise uxinzelelo kwi-mold usebenzisa umshicileli. Isitshixo sokubumba ukunyanzeliswa kukulawula izinga lokufudumeza kunye nexesha lokuhlala ukuqinisekisa isakhiwo sangaphakathi esixineneyo ngaphandle kwe-delamination. Amaqondo obushushu okubala aphakathi kwe 800 kunye ne 1200℃ukuqhubela phambili ukomeleza isihluzi segraphite ephezulu{6}}yokumelana nobushushu kunye nokuzinza kweekhemikhali.
Ukukhethwa kwe-binder nako kudlala indima kwinkqubo yokubumba i-graphite fillers. Izibophelelo eziqhelekileyo ziquka iirasi, ii-oxide zetsimbi, kunye ne-asphalt. Izibophelelo ezahlukeneyo zichaphazela i-thermal conductivity ye-thermal, i-corrosion resistance, kunye namandla omatshini. Umzekelo, i-phenolic resin ifanelekile phakathi- kunye neendawo eziphantsi zobushushu{4}, ngelixa izibophelelo zetsimbi (ezifana nomgubo wobhedu) zinokuphucula ukuxhathisa ukunxiba kwe-filler kunye ne-thermal conductivity.
Isishwankathelo, inkqubo yokubumba i-graphite filler kufuneka iphuculwe ngokusekelwe kwiimpawu zezinto ezibonakalayo, iimfuno zesicelo, kunye neemeko zezixhobo. Ngokulawula ngokuchanekileyo uxinzelelo, ubushushu, kunye nomlinganiselo wokubopha, phezulu{1}}izixhobo zokutywina zegraphite zinokuveliswa ukuhlangabezana neemfuno zemizi-mveliso zomhlwa{2}}okumelana{3}}nobushushu obuphezulu{4}}obuxhathisayo, kunye{5}}nezisombululo zokutywina ubomi obude.
