Yiziphi izinzuzo zephepha le-graphite eliguquguqukayo njengempahla yokuvala?
Iphepha le-graphitemanje isisetshenziswa kabanzi embonini yezobuchwepheshe obuphezulu. Ngokuthuthuka kwemakethe, iphepha le-graphite litholakale izinhlelo zokusebenza ezintsha, njengazoiphepha le-graphite eliguquguqukayoingasetshenziswa njengezinto zokuvala. Ngakho-ke yiziphi izinzuzo zephepha le-graphite eliguquguqukayo njengempahla yokuvala? Sizokunikeza ukuhlaziya okuningiliziwe:
Njengamanje, imikhiqizo yephepha le-graphite eguquguqukayo ikakhulukazi ihlanganisa indandatho yokupakisha,i-gasket, ukupakisha okujwayelekile, ipuleti eliyinhlanganisela elishaywa ngepuleti lensimbi, ama-gaskets ahlukahlukene enziwe ngepuleti elihlanganisiwe (eliboshiwe) elihlanganisiwe, njll. Sekusetshenziswe kabanzi ku-petrochemical, imishini, i-metallurgy, amandla e-athomu, amandla kagesi neminye imisebenzi, enokumelana okuhle kakhulu nokugqwala, ukumelana nokushisa okuphezulu, ukuncipha kanye nokululama Ukucindezeleka okumnene okuhle kakhulu kanye nezakhiwo zokuzigcoba.
Izinto zokuvala zendabuko zenziwa ikakhulukazi nge-asbestos, irabha, i-cellulose kanye nezinhlanganisela zazo. Kodwa-ke, ngokuthuthuka kwezimboni, iphepha le-graphite eliguquguqukayo njengezinto zokuvala zaqala ukusetshenziswa kakhulu. Izinga lokushisa elitholakalayo lephepha le-graphite eliguquguqukayo libanzi, elingafinyelela ku-200 ~ 450 ℃ emoyeni kanye no-3000 ℃ ku-vacuum noma emkhathini wokunciphisa, futhi i-coefficient yokwandisa okushisayo incane. Ayibi brittleness futhi iqhekeke ekushiseni okuphansi futhi ithambe ekushiseni okuphezulu. Lezi yizimo izinto zokuvala zendabuko ezingenazo. Ngakho-ke, iphepha le-graphite eliguquguqukayo lichazwa ngokuthi "inkosi yokubeka uphawu".
