Macnaha iyo mabda'a doon graphite ah

Macnaha doontii garaafitka:
Thedoon garaafit ahsaxanku waa qaab jeexdin ah, kaas oo ka kooban godad badan oo qaab W ah oo laba dhinac u janjeera oo leh laba dusha sare ee jeexdinta iyo taageerada hoose ee ka soo horjeeda, dusha hoose, wejiga sare ee dhammaadka, dusha gudaha, dhinac dibadda ah iyo joogsi ka soo horjeeda wejiga sare ee dhammaadka. Ugu yaraan hal god oo dhex mara ayaa loogu talagalay labada dusha sare ee ka soo horjeeda, Godka ilaalinta geeska waxaa si kala duwan loogu talagalay isgoyska taageerada hoose iyo labada dusha sare ee jeexdinta ee ka soo horjeeda. Dusha sare, qaybta hoose ee soo bixidda oo ay sameeyeen laba god oo laba dhinac u janjeera oo isku xiga oo W ah ayaa loogu talagalay god dhex mara oo barbar socda godka laba-geesoodka ah ee W-nooca ah, qaabka isgoyskana waa qiyaastii qaab V ah. Qaabka adeeggu wuxuu awood u siinayaa in sibidhka la simiyoxarigga carbide-kaiyo in si siman loo nadiifiyo shaambada marka la isticmaalayo habka nadiifinta haydarojiinta iyo nadiifinta faakiyuumka, si looga fogaado qallooca iyo isbeddelka badeecada, rarista badeecadaha waaweyn iyo isticmaalka yar.

Mabda'a doon graphite ah:
Saxanka doonta ee graphite wuxuu ka kooban yahay saxan doon, barkin barkin iyo meel lagu dhejiyobiiniyadoo la dhigayo meel godan oo dhinac ah, sida godka ul-rarista qalalan W. labada daraf ee jirka saxanka doonta oo barbar socda godka ul-rarista W waxaa si kala duwan loogu bixiyay godad, madaxa ku yaal dhammaadka hoose ee baloogga barkinta waxaa la mid ah godka, biinka meelayntana wuxuu dhex maraa godka meelaynta ee bartamaha godka iyo godka meelaynta ee bartamaha godka ee dhammaadka hoose ee baloogga barkinta; Masaafada u dhaxaysa salka hoose eeulQaadista godka ilaa dusha sare ee jirka doonta, masaafada u dhaxaysa sare ilaa miiska hoose ee jirka doonta, masaafada u dhaxaysa dusha sare ee baloogga barkinta ilaa miiska kore ee qaloocan, iyo masaafada u dhaxaysa dusha sare ee baloogga barkinta ee la jaanqaadaysa jirka doonta ilaa miiska hoose ee jirka doonta waa 2.0-8mm, 3-16mm, 3.8-12mm iyo 6.8-28mm siday u kala horreeyaan; Kala fogaanshaha booska, ballaca hoose ee godka, dhererka godka iyo xagasha ku jirta ee booska rarista usha W waa 2.6-12.4 mm, 0.2-3 mm, 1.2-9 mm iyo 50 ° - 60 ° siday u kala horreeyaan; Qaabka adeegga ma aha oo kaliya inuu hagaajiyo wax soo saarka foornada hal-halka ah ee foornada sintering, wuxuu dheereeyaa cimriga adeegga dhabta ah ee saxanka doonta, laakiin sidoo kale wuxuu badbaadiyaa agabka saxanka doonta.
