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 leh 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 isku xiga ayaa loo qaabeeyey iyadoo la marinayo jeexdin la siman jeexdin laba-jidka ah ee nooca W iyo qaabka iskutallaabtu waa qiyaastii V. -qaabeeya. Qaabka utility wuxuu awood u siinayaa 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, barkinta barkinta iyo meelayntapinoo leh taper gaar ah oo loo habeeyey hal dhinac, sida jeexdin usha rarista ee engegan W. labada daraf ee saxanka doonta oo barbar socda jeexdin usha rarida W siday u kala horreeyaan waxaa la siiyaa grooves, madaxa qaybta hoose ee barkinta barkinta waa oo la mid ah jeexdin, iyo pin-ku-dhigiddu wuxuu dhex maraa godka meelaynta ee dhexda jeexdin iyo godka meelaynta ee bartamaha madaxa ee cidhifka hoose ee barkinta barkinta; Fogaanta xagga hoose eeushaQaadista jeexdin w ilaa dusha hoose ee jidhka doonta, fogaanta sare ilaa miiska hoose ee jidhka doonta, fogaanta dusha sare ee barkinta barkinta ilaa miiskeeda sare, iyo fogaanta dusha sare barkinta barkinta ee la socota maydhka doonta ilaa miiska hoose ee jidhka doonta waa 2.0-8mm, 3-16mm, 3.8-12mm and 6.8-28mm siday u kala horreeyaan; 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.
