Amfani da Graphite

1. Kamar yadda refractory abu: Graphite da kayayyakin da kaddarorin na high zafin jiki juriya da kuma high ƙarfi. Ana amfani da su musamman a masana'antar ƙarfe don kera crucibles graphite. A cikin ƙera ƙarfe, graphite galibi ana amfani da shi azaman wakili na kariya don ingots na ƙarfe da na ciki na tanderun ƙarfe.

2. Conductive abu: amfani a cikin lantarki masana'antu a matsayin tabbatacce electrode ga yi na lantarki, goge, carbon sanduna, carbon shambura, mercury tabbatacce kwarara na'urorin, graphite gaskets, tarho sassa, coatings ga talabijin hoto shambura, da dai sauransu.

3. Man shafawa mai jurewa sawa: Graphite galibi ana amfani dashi azaman mai mai a cikin masana'antar injin. Sau da yawa ba a amfani da mai mai lubricating a ƙarƙashin babban sauri, babban zafin jiki da yanayin matsa lamba, yayin da kayan da ba a iya jurewa na graphite na iya aiki a babban saurin zamiya na 200 ~ 2000 ° C ba tare da lubricating mai ba. Yawancin kayan aiki waɗanda ke jigilar kafofin watsa labarai masu lalata ana amfani da su sosai a cikin kayan graphite don yin kofuna na piston, hatimi da bearings. Ba sa buƙatar man shafawa yayin aiki.

4. Graphite yana da kwanciyar hankali mai kyau. Musamman sarrafa graphite, wanda yana da halaye na lalata juriya, mai kyau thermal conductivity da low permeability, ana amfani da ko'ina a yi na zafi musayar, dauki tankuna, condensers, konewa hasumiyai, sha hasumiyai, coolers, heaters, tacewa. , kayan aikin famfo. Yadu amfani da petrochemical, hydrometallurgy, acid da alkali samar, roba fiber, takarda da sauran masana'antu sassa, na iya ajiye da yawa karfe kayan.

5. Don simintin gyare-gyare, sanding, gyare-gyaren matsawa da kayan aikin pyrometallurgical: Saboda graphite yana da ƙananan haɓakaccen haɓakawar thermal kuma yana iya tsayayya da saurin sanyi da canje-canje mai sauri, ana iya amfani dashi azaman ƙirar gilashin gilashi. Bayan amfani da graphite, za a iya amfani da ƙarfe na ƙarfe don samun ingantattun ma'auni na simintin gyare-gyare da ƙimar ƙasa mai tsayi. Ana iya amfani da shi ba tare da sarrafawa ba ko ɗan aiki kaɗan, don haka adana ƙarfe da yawa.

6, don masana'antar makamashin atomic da masana'antar tsaro ta ƙasa: graphite yana da mai daidaita neutron mai kyau don amfani a cikin injin sarrafa atomatik, uranium-graphite reactor shine mafi yawan amfani da injin atomatik. The decelerating abu a cikin nukiliya reactor a matsayin tushen wutar lantarki ya kamata ya sami wani babban narkewa batu, barga, kuma lalata-resistant kaddarorin, kuma graphite iya cikakken cika da sama bukatun. Tsaftar graphite da aka yi amfani da shi azaman mai sarrafa atomic yana da girma sosai, kuma abun cikin najasa bai kamata ya wuce dubun PPM ba. Musamman, abun cikin boron yakamata ya zama ƙasa da 0.5 PPM. A cikin masana'antar tsaro, ana kuma amfani da graphite don kera roka mai ƙarfi mai ƙarfi, cones na hanci mai linzami, sassa na kayan kewaya sararin samaniya, kayan rufewa da kayan kariya na radiation.

7. Graphite kuma yana hana gurbataccen ruwa. Ƙara wani adadin foda na graphite zuwa ruwa (kimanin gram 4 zuwa 5 a kowace tan na ruwa) yana hana lalata a saman tukunyar jirgi. Bugu da kari, graphite za a iya mai rufi a karfe bututun hayaki, rufi, gadoji da kuma bututu don hana lalata da tsatsa.
8. Za a iya amfani da zane a matsayin fensir gubar, pigment, da polishing wakili. Bayan aiki na musamman na graphite, ana iya samar da kayan musamman na musamman don sassan masana'antu masu dacewa.
9. Electrode: Graphite na iya maye gurbin jan ƙarfe a matsayin lantarki. A cikin shekarun 1960, an yi amfani da jan ƙarfe sosai azaman kayan lantarki, tare da ƙimar amfani da kusan kashi 90% da graphite kusan 10%. A cikin karni na 21st, masu amfani da yawa sun fara zaɓar graphite a matsayin kayan lantarki, a Turai, fiye da 90%. Kayan lantarki na sama shine graphite. Copper, wanda ya taɓa mamaye kayan lantarki, ya kusan rasa fa'idodinsa idan aka kwatanta da na'urorin lantarki na graphite. Graphite a hankali yana maye gurbin jan ƙarfe azaman kayan zaɓi na lantarki na EDM.
