Za a iya amfani da foda mai zane a matsayin fensir, don haka me yasa za'a iya amfani da foda na graphite azaman fensir? Ka sani? Karanta shi tare da edita!
Da farko dai, graphite foda yana da laushi kuma yana da sauƙin yanke, kuma graphite foda yana da lubricious da sauƙin rubutu; Dangane da dalilin da ya sa za a yi amfani da fensir na 2B a jarrabawar shiga kwaleji, ya kamata a yi amfani da halayensa. Abu na biyu, dangane da kaddarorin sinadarai, graphite foda yana kunshe da sinadarin C, kuma sinadarai na sinadarin C suna da inganci a yanayin zafin daki, don haka yin amfani da fensir mai graphite don yin rikodin fayiloli na iya adana lokaci mai tsawo.
Graphite foda yana da abubuwa na musamman masu zuwa saboda tsarinsa na musamman:
1) High-zazzabi juriya: Graphite foda yana da wani narkewa batu na 3850 50 ℃ da wani tafasar batu na 4250 ℃. Koda an kona ta da ultra-high zafin baka, asarar nauyi da haɓakar haɓakar thermal ƙanƙanta ne. Ƙarfin graphite foda yana ƙaruwa tare da karuwar zafin jiki, kuma ƙarfin graphite foda ya ninka a 2000 ℃.
2) Ƙarfafawa da Ƙarfafawar thermal: Ƙarfafawar graphite foda shine sau ɗari fiye da na ma'adinan da ba na ƙarfe ba. Ƙarfin zafi ya wuce na kayan ƙarfe kamar ƙarfe, ƙarfe da gubar. Ƙarƙashin zafin jiki yana raguwa tare da karuwar zafin jiki, kuma ko da a matsanancin zafin jiki, graphite foda ya zama insulator. Graphite foda zai iya gudanar da wutar lantarki saboda kowane carbon atom a cikin graphite foda kawai yana samar da haɗin haɗin gwiwa guda uku tare da sauran ƙwayoyin carbon, kuma kowane carbon atom har yanzu yana riƙe da electron kyauta ɗaya don canja wurin caji.
3) Lubricity: The lubricating dukiya na graphite foda ya dogara da girman graphite foda Sikeli. Mafi girman ma'auni, ƙarami da ƙarancin juzu'i kuma mafi kyawun kayan mai mai.
4) Chemical kwanciyar hankali: Graphite foda yana da kyau sinadaran kwanciyar hankali a dakin da zazzabi, kuma zai iya tsayayya da acid, alkali da Organic sauran ƙarfi lalata.
5) Plasticity: Graphite foda yana da kyau tauri kuma ana iya niƙa shi cikin yankan bakin ciki.
6) Juriya na girgiza zafi: Graphite foda zai iya jure wa canjin yanayin zafi a dakin da zafin jiki ba tare da lalacewa ba. Lokacin da zafin jiki ya canza ba zato ba tsammani, ƙarar graphite foda ba ya canzawa da yawa kuma fasa ba zai faru ba.
Saya graphite foda, maraba zuwa Qingdao Furuite Graphite Factory, za mu samar muku da gamsasshen sabis, don haka ba ku da damuwa!
