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 kashi 90% kuma 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 rinjayen 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 injina naGraphite 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 abu ba shi da lahani ga lalacewa.Matsakaicin 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 lantarki ta hanyar fitarwa;More dace da aikace-aikace na manyan mold.
(3) yawan shayarwa ya fi ƙanƙanta;Tunda man walƙiya shima yana ɗauke da ƙwayoyin atom ɗin C, yayin da ake sarrafa fitar da ruwa, yawan zafin jiki yana haifar da ɓarnawar atom ɗin C da ke cikin mai na tartsatsin, wanda kuma ya samar da wani fim mai kariya a saman graphite electrode, wanda ke rama asarar da graphite electrode ya yi. .
(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 goge;Tun da graphite yana da kashi biyar kawai na juriya na yanke na jan karfe, yana da sauƙi don niƙa da goge da hannu
(6) ƙananan farashin kayan aiki da ƙarin kwanciyar hankali;Sakamakon hauhawar farashin jan karfe a cikin 'yan shekarun nan, farashin graphite isotropic ya kasance ƙasa da na jan karfe.A ƙarƙashin wannan ƙarar, farashin samfuran samfuran graphite na toyo carbon shine 30% ~ 60% ƙasa da na jan karfe, kuma farashin ya fi karko, canjin farashin ɗan gajeren lokaci kaɗan ne.
Saboda wannan fa'ida mara misaltuwa, graphite a hankali ya maye gurbin jan ƙarfe azaman kayan da aka fi so don lantarki na EDM.
