Sida magacu soo jeediyo, alaabooyinka graphite waa dhammaan noocyada qalabka garaafyada iyo alaabada garaafyada qaabaysan ee gaarka ah ee lagu farsameeyo aaladaha mashiinka CNC iyadoo lagu saleynayo alaabta ceeriin ee garaafka, oo ay ku jiraan graphite crucible, saxan garaafka, ul garaafyada, caaryada garaafka, kuleyliyaha graphite, sanduuqa garaafka , graphite rotor iyo taxane kale oo alaabta graphite.
Waqtigan xaadirka ah, alaabta graphite ayaa si weyn loogu isticmaalaa warshadaha magnet joogto ah ee dhulka naadir. Alaabooyinka garaafka ugu weyn ee loo isticmaalo warshadahan waa sanduuqyada graphite ee sintering, oo sidoo kale loo yaqaan kartuunada dhagaxa, doonta graphite iyo wixii la mid ah.
Marka hore, aynu soo bandhigno waxa dhif ah dhulka magnet joogto ah, iyo codsiga iyo isticmaalka alaabta graphite ee wax soo saarka ee warshadaha this. Maaddada birta ah ee naadirka ah ee dhulka waa nooc ka mid ah walxaha magnetic, kaas oo laga sameeyay daawaha ka kooban samarium, neodymium isku dhafan birta dhulka dhif iyo birta kala guurka (sida cobalt, birta, iwm), sinteed by habka metallurgy budada iyo magnetized by magnetized by magnetic. beerta. Alaabta birlabeedka joogtada ah ee dhulka waxa loo qaybiyaa SmCo magnet joogto ah iyo NdFeB magnet joogto ah. Waxaa ka mid ah, sheyga tamarta magnetic ee magnetka SmCo waa inta u dhaxaysa 15-30 mgoe, iyo kan magnetka NdFeB wuxuu u dhexeeyaa 27-50 mgoe, kaas oo loo yaqaan "boqor magnet joogto ah". Samarium cobalt magnet joogto ah, in kasta oo ay leedahay sifooyin bir ah oo aad u wanaagsan, waxaa ku jira samarium bir dhif ah iyo kobalt, kuwaas oo ah kobalt bir istiraatijiyadeed naadir ah oo qaali ah. Sidaa darteed, horumarkeeda si weyn ayaa loo xaddiday. Sannado badan oo dadaal ah cilmi-baarayaasha sayniska ee Shiinaha ka dib, gobolka ayaa maal-galiyay lacag badan oo ku saabsan warshadaha, iyo birta cusub ee naadirka ah ee dhulka iyo birta dhifka ah ee birta nitrogen-ka birta ah ee alaabada magnetka joogtada ah ayaa la horumariyay, Waa suurtagal in la noqdo jiil cusub oo ah naadirka dhulka magnet daawaha joogtada ah. Wax soo saarka qalabka birlabku wuxuu u baahan yahay in la isticmaalo kiis garaafeed si loogu dhufto heerkulka sare ee foornada faakuumka. Qalabka birta ah ee joogtada ah waxay ku xiran yihiin dusha gudaha ee kiiska graphite ee heerkulka isku midka ah, iyo qalabka birlabeedka joogtada ah ee loo baahan yahay iyo aluminium magnetic joogto ah ayaa ugu dambeyntii la safeeyey.
Sida soo saaraha ee alaabta graphite, sanduuqa graphite (goobka graphite, kartoonada graphite) ay soo saartay Zhonghong qalab cusub waxaa si weyn loo isticmaalo in saarayaasha dhulka dhif ah magnet joogto ah, oo waxaa ammaanay macaamiisha iyo aasaasay xiriir iskaashi muddo dheer xasilloon!
