Macnaha iyo mabda'a doon graphite

Macnaha doon graphite:
Thedoon graphitesaxantu waa caaryada jeexjeexa, taas oo ka kooban tiro badan oo ah W-qaabeeya jeexdin laba geesood ah oo ka soo horjeeda laba sagxadood oo jeexdin ah iyo soo bixitaan taageero hoose ah, dusha hoose, wejiga dhamaadka sare, dusha gudaha, dhinac dibadda ah iyo joogsi ka soo horjeeda wejiga dhamaadka sare. Ugu yaraan hal qiiqa dhex jeexdin ayaa loogu talagalay on lid ku ah labada dusha jeexdin siday u kala horreeyaan, A jeexdin ilaalinta gees siday u kala horreeyaan waxaa loogu talagalay isgoyska soo bixista taageerada hoose iyo labada dusha jeexdin ka soo horjeeda. Dusha hoose, qaybta hoose ee soo bixista oo ay sameysteen laba nooc oo W-nooc ah oo laba-jid ah oo u janjeera dhinaca jeexjeexa ayaa loo qaabeeyey iyadoo la marinayo jeexdin la siman jeexdin laba-jidka ah ee nooca W iyo qaabka qaybta iskutallaabtu waa qiyaastii V-qaabeeya. Qaabka utility wuxuu awood u leeyahay sibidhkaxariijin carbideiyo badeecooyinka xaashida ah in si siman loo jeexjeexo habka loo yaqaan hydrogen degumming iyo vacuum sintering, si looga fogaado is-geddisnaanta badeecada iyo qallafsanaanta, rarida alaabta waaweyn iyo isticmaalka yar.

Mabda'a doonta garaafka:
Saxanka doonta graphite waxa uu ka kooban yahay saxanka doonta, barkin barkin iyo meel dhigidpinoo leh taper gaar ah oo loo habeeyey hal dhinac, sida jeex jeex ah oo qallalan W. labada daraf ee saxanka doonta ee barbar socda jeexdin usha rarida W ayaa siday u kala horreeyaan loo bixiyaa jeexjeexyada, madaxa cidhifka hoose ee barkinta barkinta ayaa la barbardhigayaa jeexdin, iyo pin-ku dhejinta wuxuu dhex maraa godka meelaynta ee badhtamaha booska madaxa ee badhtamaha booska madaxa ee hoose. xannibaad; Fogaanta xagga hoose eeushaQaadista jeexdin w ilaa korka hoose ee jidhka doonta, fogaanta sare ilaa miiska hoose ee jidhka doonta, fogaanta dusha sare ee barkinta barkinta ilaa miiska sare ee barkinta, iyo fogaanta dusha sare ee barkinta barkinta oo la mid ah jidhka doonta ilaa miiska hoose ee jidhka doonta waa 2.0-8mm, 3-16mm, 3.8-1mmly respectively. Fogaanta booska, ballaca hoose ee booska, dhererka booska iyo xagasha ku jirta booska rarka Usha W waa 2.6-12.4 mm, 0.2-3 mm, 1.2-9 mm iyo 50 ° – 60 ° siday u kala horreeyaan; Qaabka tasiilaadka kaliya ma wanaajiyo wax soo saarka foornada kaliya ee foornada sinta, waxay sii dheeraysaa nolosha adeegga dhabta ah ee saxanka doonta, laakiin sidoo kale waxay badbaadisaa alaabta saxanka doonta.
