The extrusion ndondomeko akhoza kugawidwa m'magawo awiri: siteji yoyamba ndi compaction ndi preloading, amene pamodzi amatchedwa siteji jacking. Ndi Pambuyo pake phala litakwezedwa m'chipinda chakuthupi ndikukweza pakamwa pakamwa, plunger imagwiritsidwa ntchito kukakamiza phala, ndipo kupanikizika kumafalikira kumadera onse, kuti phala likhale wandiweyani. Munthawi imeneyi, kukakamiza, mphamvu ndi kuyenda (kusuntha) kwa phala ndizofanana ndi kuumba. Gawo lachiwiri ndi extrusion. Pambuyo phala ndi precompressed, chotsani precompression, chotsani baffle, ndiyeno repressurize phala, extrude phala pakamwa kufa, ndi kudula molingana ndi utali wofunika, amene ndi mankhwala a utali wofunika ndi mawonekedwe.
Kuphika ndi njira yofunika kwambiri yaukadaulo pakupanga ma elekitirodi, komanso yovuta kwambiri. Pali kusintha kwa thupi ndi kusintha kwa mankhwala mu njirayi. Mphamvu zamakina, kapangidwe ka mkati ndi katundu wa electrode ya graphite zimadalira kuchuluka kwa binder komwe kumasinthidwa kukhala coke panthawi ya calcination, ndipo zida zamakina zimagwirizana mwachindunji ndi mtengo wophika. Choncho aliyense kupanga graphite elekitirodi wa zoweta lalikulu fakitale kuti kuphika ndi zofunika kwambiri. Kwa ma elekitirodi a graphite okhala ndi mphamvu yayikulu komanso mphamvu yayikulu, kuwonjezera pakuwonjezera koyenera kwa singano ya singano mu osakaniza.
Kuphatikiza apo, iyenera kuwotchedwa kawiri kapena katatu.
Pambuyo potsukidwa pamwamba pa zophikidwa zomwe zatsirizidwa, zimayikidwa muzitsulo zachitsulo, zolemera poyamba ndikuziyika mu thanki yotenthetsera kuti itenthe. Malinga ndi kusiyanasiyana kwa ma elekitirodi, lolingana preheating nthawi ndi maola 6 kwa elekitirodi pansipa Φ 450mm, maola 8 ma elekitirodi pakati Φ 450 ndi Φ 550mm, 10 ma elekitirodi pamwamba Φ 550mm ndi 280-320 ℃. The preheated mankhwala mwamsanga kuikidwa mu thanki impregnating pamodzi ndi chitsulo chimango. Asanalowetsedwe, thanki yotenthetsera idatenthedwa mpaka 100 ℃, chivundikiro cha thanki chimatsekedwa, ndipo digiri ya vacuum iyenera kukhala pamwamba pa 600mmhg, ndipo imasungidwa kwa mphindi 50. Pambuyo vacuumizing, malasha phula phula impregnating wothandizila anawonjezera, ndiyeno kuthamanga ntchito kukanikizira wothandizila impregnating mu dzenje mpweya wa elekitirodi. Pambuyo vacuumizing, onani ngati pali madzi wothinikizidwa mpweya chitoliro. Ngati pali madzi, tsitsani poyamba, apo ayi zidzakhudza kuchuluka kwa kulemera. Kenako sankhani nthawi yoyenera yokakamiza molingana ndi kukula kwa electrode, nthawi zambiri maola anayi. Chiŵerengero cha kulemera chinawonjezeka pambuyo impregnation kwa kulemera pamaso impregnation ntchito kuyeza ngati impregnated mankhwala akukwaniritsa zofunika. Mtundu wa Mofananamo, kuti apititse patsogolo khalidwe la mankhwala ndi kukwaniritsa zofuna za makasitomala, electrode theka-anamaliza mankhwala pambuyo kuphika ayeneranso kulowetsedwa kawiri kapena katatu.
Zomwe zimatchedwa graphitization ndi njira yochizira kutentha kwambiri (nthawi zambiri pamwamba pa 2300 ℃) yomwe imasintha netiweki ya ndege ya atomu ya kaboni ya hexagonal kuchoka pawiri-dimensional chipwirikiti chophatikizika kupita ku magawo atatu olamulidwa ndi ma graphite. Kunena mosabisa, carbon imasandulika kukhala graphite. Kusiyana kwakukulu pakati pa zinthu zokazinga ndi zinthu zopangidwa ndi graphitized ndi atomu ya kaboni ndi atomu ya kaboni.
Electrode processing imagawidwa m'njira zinayi: kutembenuza bwalo lakunja, gawo lathyathyathya, dzenje loboola ndi ulusi wopota. Pakupanga kwakukulu, ma lathe atatu angagwiritsidwe ntchito poyendetsa. Bwalo lakunja la thupi la elekitirodi sikuti limangopangitsa kuti chinthucho chifike pamlingo winawake, komanso kuthetsa zolakwika monga kupindika ndi kupindika komwe kumachitika chifukwa cha njira yapitayi. Potembenuza bwalo lakunja, mapeto amodzi a electrode amamangiriridwa ndi chuck, mapeto ena amawerengedwa ndi pakati, chida chotembenuza chimakanizidwa pa chonyamulira, chida chotembenuza chimafika pamalo oyenera, chogwirira ntchito chimazungulira pambuyo poyambitsa lathe. , ndi chida chokhotakhota ndi chopingasa Pitani ku njira, ndipo kukonza kutha kutha nthawi imodzi. Zogulitsa zomwe zatsirizidwa zimatha kuperekedwa kunjira yotsatira, gawo lathyathyathya komanso lotopetsa. Ichi ndi chimango chapakati chokhala ndi zofananira zomwe zimayikidwa pa lathe, ndipo kumapeto kwa electrode kumakhala ndi chuck Mtundu wa Kumamatira, mapeto enawo nthawi zambiri amathandizidwa ndi chimango chapakati patali kuchokera ku malekezero awiri, ndipo dzenje lolumikizana limakhala lonyowa pambuyo poti gawolo laphwanyidwa, kapena zida ziwiri zokhotakhota zitha kukhazikitsidwa pa chimango cha chida ndikusunthira mkati, ndipo mapeto ena akhoza kukonzedwa pambuyo pa mapeto amodzi. Pambuyo pokonza chinthu choyamba, yang'anani coaxiality ya chuck ndi chimango chapakati, ngati sichoncho, sinthani nthawi yomweyo. Kupanga ulusi mu dzenje lolumikizana, njirayi imatha kuchitika podula ulusi kapena chodula mphero. Ulusi wopangidwa ndi mphero wodula umakhala wabwino kwambiri komanso wochita bwino kwambiri. Kukonza kumachitika pa lathe yokhala ndi chimango chapakati ndi chodula mphero. Mapeto amodzi a electrode amamangiriridwa ndi chuck, ndipo mapeto ena amagwiridwa ndi chimango chapakati. Pambuyo poyambitsa lathe, electrode imayenda pang'onopang'ono, ndipo wodula mphero amayenda mofulumira Njirayi ndi yofanana, pambuyo pa kukhazikitsa zida, ulusi umaphwanyidwa kamodzi, ndipo ulusi umaphwanyidwa. Pambuyo pokonza koyamba, ma geji asanu amagwiritsidwa ntchito kuti ayang'ane coaxiality <0.01, kuzungulira <0.03, m'mimba mwake ndi flatness <0.01, ndipo kukonzanso kungapitirire pokhapokha mutadutsa kuyendera. Zogulitsa zomwe zakonzedwa zimayikidwa m'malo osungira pambuyo poyang'aniridwa
Graphite elekitirodi antioxidant macerate ndi kuwala woyera kapena colorless pafupifupi mandala madzi opangidwa ndi nanometer ceramic particles omwazikana mu zosungunulira madzi. The madzi likulowerera mu pores wa graphite zakuthupi ndi kupanga woonda zoteteza filimu ya mkulu kutentha kukana padziko pores ndi graphite masanjidwewo. Izi wosanjikiza wa filimu zoteteza angalepheretse mpweya ndi graphite zakuthupi mwachindunji kukhudzana makutidwe ndi okosijeni anachita. Komanso, madutsidwe a graphite zakuthupi si anakhudzidwa, ndi filimu anapanga pamwamba graphite masanjidwewo ndi pores sadzasweka kapena peel off.

Pofuna kukonza zokolola za elekitirodi graphite ndi kuchepetsa mtengo kupanga, tiyenera mosamalitsa kulamulira magawo ndondomeko. Kupyolera mu kuwunika kozama kwa kupanga njira iliyonse yopangira, magawo opangirawo amagwirizana kwambiri ndi magawo omwe adakhazikitsidwa. Waukulu khalidwe chinthu cha graphite elekitirodi lagona Kugawa zinthu ndi kulamulira ndondomeko. Chifukwa chake, kuyang'anira mu labotale ndikofunikira kwambiri, ndipo kuyang'anira gulu lililonse lazinthu zopangira ndi kuwunika pakupanga ndikofunikira.
