| Qaphela: · Ngaphansi kwezinga lokushisa elisebenzayo elingu-20℃±2℃, ngaphezu kwamapharamitha kazibuthe kanye nezakhiwo ezibonakalayo kuyahlolwa, ngokulahleka okungenakugwenywa kwamandla kazibuthe okungaphezu kuka-5%.· Izinga lokushisa eliphezulu likazibuthe elisebenzayo liyashintsheka ngenxa yesilinganiso sobude nobubanzi kanye nezici zendawo. . | ||||||||
Inzuzo:
Izakhiwo zalawa zidonsa ziphakeme kakhulu kunalezo zendabuko futhi njengamanje yizo ezinamandla kakhulu ekusebenzeni. Ukuphakama kwabo
ukuphoqelela kanye nokuhlala okuphezulu kuvumela ukuklama okusha kanye nethuba lokwandisa inkambu kazibuthe yohlelo lokusebenza lapho isikhala silinganiselwe
noma lapho kudingeka khona inkambu kazibuthe enamandla.
Ozibuthe be-NdFeB basengozini enkulu yokugqwala. Ngakho-ke zidinga isivikelo ebusweni enamathela. Ukusetshenziswa kwamagnetic we-NdFeB kunesimo
ngezinga lokushisa elivela ku-80ºC kuya ku-230ºC. Futhi isebenza ezingeni lokushisa elingaphansi kuka-0 ℃.
Isicelo:
Ozibuthe be-Neodymium basetshenziswa njengezinhlobo ezahlukahlukene zamalensi kazibuthe wokugxila, ukuphambuka kwezinhlayiya ezishajwa ku-electronics, ama-brake systems,
i-drip, inzwa, isistimu kazibuthe ku-rotor kanye nama-micro motors, kanye nomkhakha wesayensi, imithi (i-tomography, i-NMR spectrometers), njll.
Namuhla, omazibuthe be-NdFeB basetshenziswa ngobuningi emhlabeni wonke. Ukuthuthukiswa kwalokhu kwaziswa akukakapheleli; ukudumala
futhi amandla ensimu ephoqelelayo ayandiswa ngokuqhubekayo. Amandla aphezulu wozibuthe be-NdFeB asho ukuthi amamotho nezinzwa zingakhiwa
kancane kancane - futhi lokhu kusho ukwanda kokusebenza kahle. Ukuthuthukiswa okuqhubekayo kwenza le nto ethokozisayo ikwazi ukuqhubeka
ngokwethulwa ezindaweni ezintsha.
Wonke amanani ashiwo anqunywa kusetshenziswa amasampula ajwayelekile ngokuya nge-IEC 60404-5. Ukucaciswa okulandelayo kusebenza njengamavelu ereferensi kanye
ingase yehluke. Ukuze uthole ulwazi olwengeziwe sicela uxhumane nonjiniyela bethu bezicelo.
