Ta yaya graphite zai iya maye gurbin jan ƙarfe azaman lantarki? RabawaHigh inji ƙarfi Graphite Electrode China.
A cikin shekarun 1960, an yi amfani da jan ƙarfe sosai azaman kayan lantarki, tare da ƙimar amfani da lissafin kusan 90% da graphite kawai kusan 10%. A cikin karni na 21st, masu amfani da yawa sun fara zaɓar graphite azaman kayan lantarki. A Turai, fiye da 90% na kayan lantarki shine graphite. Copper, da zarar mafi girman kayan lantarki, ya kusan rasa gefensa akan graphite. Menene ya haifar da wannan gagarumin canji? Hakika, akwai da yawa abũbuwan amfãni daga graphite lantarki.
(1) saurin aiki da sauri: gabaɗaya, saurin sarrafa injinGraphite Electrode na siyarwazai iya zama 2 ~ 5 sau sauri fiye da na jan karfe; Duk da haka, edm yana da sauri sau 2 ~ 3 fiye da jan karfe, kuma kayan ba su da lahani ga lalacewa. Wurin laushi na jan karfe yana da kusan digiri 1000, kuma yana da sauƙi don lalacewa ta hanyar zafi. Graphite sublimation zafin jiki na 3650 digiri; Matsakaicin haɓakar haɓakar thermal shine kawai 1/30 na jan ƙarfe.
(2) nauyi mai nauyi: nauyin graphite shine kawai 1/5 na jan karfe, wanda zai iya rage nauyin kayan aikin injin (EDM) yadda ya kamata lokacin da ake sarrafa manyan na'urori ta hanyar fitarwa; More dace da aikace-aikace na manyan mold.
(3) yawan zubar da ruwa ya fi karami; Tunda man spark din shima yana dauke da sinadarin C, yayin da ake sarrafa fitar da ruwa, yawan zafin jiki yakan haifar da rugujewar atom din C dake cikin mai, wanda hakan ya haifar da wani fim mai kariya a saman graphite electrode, wanda hakan zai biya diyya ga asarar da aka samu na graphite electrode. .
(4) ba bura; Bayan an sarrafa na'urar jan ƙarfe, ana buƙatar gyara shi da hannu don cire burrs, yayin da graphite ke sarrafa taGraphite Electrode factoryba tare da burrs ba, wanda ke adana kuɗi da yawa kuma yana sauƙaƙa sarrafa samarwa ta atomatik
(5) graphite ya fi sauƙi don niƙa da gogewa; Tun da graphite yana da kashi biyar kawai na juriya na yanke na jan karfe, yana da sauƙin niƙa da gogewa da hannu
(6) ƙananan farashin kayan aiki da ƙarin kwanciyar hankali; Saboda hauhawar farashin jan karfe a cikin 'yan shekarun nan, farashin graphite isotropic ya kasance ƙasa da na jan karfe. A karkashin wannan girma, farashin janar graphite kayayyakin na toyo carbon ne 30% ~ 60% kasa da na jan karfe, kuma farashin ya fi barga, da gajeren lokaci farashin canji ne kadan.
Saboda wannan fa'ida mara misaltuwa, graphite a hankali ya maye gurbin jan ƙarfe azaman kayan da aka fi so don lantarki na EDM.
