Maitiro ekugadzira maumbirwo akaiswa
Impregnation idanho rekusarudzika rinoitwa kuitira kuvandudza zvimiro zvechigadzirwa chekupedzisira.Tars, Pitches, resins, simbi dzakanyungudutswa uye mamwe mareagents anogona kuwedzerwa kune akabikwa maumbirwo (mune akakosha maficha magirafu maumbirwo anogona zvakare kuiswa) uye mamwe mareagents anoshandiswa kuzadza ma voids akaumbwa mune carbonised zvinhu.Kunyura nekupisa tara yemarasha ine kana isina vacuum uye autoclaving inoshandiswa.Nzira dzakasiyana dzekuisa pamuviri dzinoshandiswa zvichienderana nechigadzirwa senge asi batch kana quasi-kuenderera mberi maoparesheni anoshandiswa.Iyo impregnation cycle inowanzo sanganisira preheating maumbirwo, impregnation uye kutonhora.Inoomesa reactor inogona kushandiswa zvakare.Electrodes iyo ichave yakamisikidzwa inogona kupiswa nekupisa kwemarara kweiyo thermal oxidiser.Chete makabhoni akasarudzika anoiswa nesimbi dzakasiyana.Izvo zvakabikwa kana graphised zvikamu zvinogona kuisirwa pamwe nezvimwe zvinhu, semuenzaniso resins kana simbi.Impregnation inoitwa nekunyura, dzimwe nguva pasi pevacuum uye dzimwe nguva pasi pekumanikidzwa, autoclaves inoshandiswa.Zvikamu zvakaiswa pamuviri kana kusungwa nemarasha tara zvinodzoreredzwa.Kana resin bonding yakashandiswa, inorapwa.
Maitiro ekugadzira maumbirwo akadzokororwa kubva kune akaiswa pamuviri
Kubika nekubika patsva Kubikazve kunoshandiswa chete kune maumbirwo asina pamuviri.Maumbirwo egirinhi (kana maImpregnated shapes) anodzoserwa patembiricha inosvika 1300 °C vachishandisa mavira akasiyana senge tunnel, single chamber, multiple chamber, annular uye push rod furnaces zvichienderana nekukura nekuoma kwechigadzirwa.Kuramba kubheka kunoitwa zvakare.Mashandiro echoto akafanana neaya anoshandiswa kugadzira ma electrode kubheka maitiro, asi iyo
mavira kazhinji maduku.
