M'madera amasiku ano omwe maginito amagwiritsidwa ntchito kwambiri, zinthu zonse za samarium cobalt ndi neodymium iron boron zimagwira ntchito zosiyanasiyana. Kwa oyamba kumene mumakampani, ndikofunikira kwambiri kusankha zinthu zomwe zimagwirizana ndi malonda anu. Lero, tiyeni tione mozama makhalidwe a zipangizo ziwiri zosiyanazi ndikuwona kuti ndi iti yomwe ili yoyenera pa zosowa zanu.
1. Kuyerekeza kwa magwiridwe antchito
Maginito katundu
NdFeB ndiye amphamvu odziwika okhazikika maginito zakuthupi ndi mkulu kwambiri maginito mphamvu mankhwala. Izi zimapangitsa kuti zikhale zabwino kwambiri pazogwiritsa ntchito zomwe zimafuna mphamvu yamphamvu ya maginito. Mwachitsanzo, m'munda wa ma motors, ma mota omwe amagwiritsa ntchito maginito a NdFeB amatha kupanga torque yayikulu ndikupereka mphamvu zolimba pazida. Maginito a maginito a SmCo okhazikika sayenera kunyalanyazidwa. Atha kukhalabe okhazikika maginito m'malo otentha kwambiri. Mbali iyi ya SmCo imapangitsa kuti ikhale yodziwika bwino m'malo ena apadera ogulitsa omwe ali ndi kutentha kwakukulu.
Kukhazikika kwa kutentha
Ubwino umodzi waukulu wa zinthu za SmCo ndikukhazikika kwake kwa kutentha. M'madera otentha kwambiri, kuwonongeka kwa maginito kwa maginito a SmCo okhazikika kumakhala kochepa kwambiri kuposa kwa NdFeB. Mosiyana, ngakhale NdFeB ali amphamvu maginito katundu, kutentha kulolerana ndi ofooka, ndi sizingasinthe demagnetization akhoza kuchitika pa kutentha.
Kukana dzimbiri
Pankhani ya kukana dzimbiri, zida za SmCo zimagwira bwino ntchito m'malo ena onyezimira komanso owononga mpweya chifukwa cha kukhazikika kwawo kwamankhwala. Komabe, ngati zida za NdFeB zilibe zokutira zoyenera zoteteza, zimatha kuwonongeka m'malo ofanana, zomwe zimakhudza momwe amagwirira ntchito komanso moyo wawo wautumiki. Komabe, ndi chitukuko cha umisiri pamwamba mankhwala, kukana dzimbiri wa NdFeB nawonso pang'onopang'ono kusintha.
2. Minda yofunsira
Minda yogwiritsira ntchito zinthu za SmCo
Samarium cobalt zokhazikika maginito zipangizo ntchito kwambiri m'minda apamwamba monga Azamlengalenga, asilikali, ndi zachipatala. M'dongosolo la injini za ndege, maginito okhazikika a SmCo amatha kugwira ntchito mokhazikika pakutentha kwambiri komanso m'malo ovuta kugwedezeka kwamakina kuti atsimikizire kuwongolera bwino kwa injini. M'makina owongolera mizinga ndi magawo owongolera ma satellite m'gulu lankhondo, zida za SmCo zimayamikiridwanso chifukwa chokhazikika komanso kukhazikika kwake. Pazida zamankhwala, monga zida zina zazikulu zamaginito pazida zamaginito zamaginito (MRI), kugwiritsa ntchito maginito okhazikika a SmCo kumatsimikizira kulondola kwa zida pansi pamikhalidwe yayitali komanso yolimba kwambiri.
Minda yogwiritsira ntchito zinthu za NdFeB
NdFeB okhazikika maginito zipangizo akhala ankagwiritsa ntchito m'munda wamba chifukwa katundu wawo wamphamvu maginito ndi mtengo wotsika. Mwachitsanzo, muzinthu zathu zamagetsi zomwe timagula monga ma hard drive, ma speaker mafoni am'manja, ndi mahedifoni, maginito okhazikika a NdFeB amawapatsa mphamvu yamagetsi yaying'ono komanso yamphamvu. M'magalimoto amagetsi amagetsi atsopano, kugwiritsa ntchito NdFeB kwathandizanso kwambiri kuyendetsa bwino kwa ma motors ndikulimbikitsa chitukuko chamakampani opanga magalimoto atsopano. Komanso, NdFeB komanso mbali yofunika injini zosiyanasiyana, masensa ndi zipangizo zina m'munda wa zochita zokha mafakitale.
3. Zinthu zamtengo wapatali
Mtengo wazinthu zopangira
Zigawo zazikulu za SmCo okhazikika maginito zipangizo, samarium ndi cobalt, ndi osowa zitsulo zinthu, ndi migodi awo ndi kuyenga ndalama ndi mkulu, zomwe zimabweretsa kukwera mtengo kwa zipangizo SmCo mankhwala. Pakati pa zigawo zikuluzikulu za NdFeB, neodymium, chitsulo ndi boron, chitsulo ndi boron ndizofala komanso zotsika mtengo. Ngakhale neodymium ndi chinthu chosowa padziko lapansi, NdFeB ili ndi zabwino zina pamtengo wamtengo wapatali poyerekeza ndi SmCo.
Mtengo wokonza
Pa processing, SmCo zipangizo ndi zovuta pokonza chifukwa cha kuuma awo mkulu ndi makhalidwe ena, ndi processing mtengo ndi mkulu. NdFeB zipangizo ndi zosavuta pokonza, koma chifukwa makutidwe ndi okosijeni mosavuta ndi makhalidwe ena, miyeso yapadera zoteteza chofunika pa processing, amenenso kumawonjezera processing mtengo kumlingo wakutiwakuti.
4. Momwe mungasankhire chinthu choyenera kwa inu
Ganizirani kutentha kwa ntchito
Ngati mankhwalawa amagwiritsidwa ntchito pamalo otentha kwambiri, monga kupitirira 150 ℃ kapena kupitirira apo, monga pafupi ndi ng'anjo zotentha kwambiri zamafakitale ndi zida zamaginito kuzungulira injini zakuthambo, zinthu za samarium cobalt ndizosankha zoyenera kwambiri. Chifukwa kukhazikika kwake pa kutentha kwakukulu kumatha kuonetsetsa kuti ntchito yokhazikika kwa nthawi yayitali ndikupewa zovuta za demagnetization chifukwa cha kukwera kwa kutentha. Ngati kutentha ntchito ndi firiji kapena m'munsimu 100 ℃, monga mankhwala ambiri wamba pakompyuta, ambiri Motors mafakitale, etc., NdFeB mankhwala akhoza kukumana ndi zosowa ndipo angapereke sewero lathunthu kwa katundu wawo mkulu maginito.
Ganizirani zofunikira zolimbana ndi dzimbiri
Ngati chinthucho chidzagwiritsidwa ntchito mumlengalenga wonyowa, wowononga mpweya, monga zida za maginito pazida zomwe zili m'mphepete mwa nyanja ndi zomera zamankhwala, kukana kwa dzimbiri kuyenera kuganiziridwa. Kukhazikika kwamankhwala a samarium cobalt chuma palokha kumapangitsa kukhala kopindulitsa kwambiri m'malo ano. Komabe, ngati mankhwala NdFeB ankachitira ndi ❖ kuyanika apamwamba zoteteza, akhoza kukumana ndi dzimbiri kukana zofunika pamlingo wakutiwakuti. Panthawiyi, ndikofunikira kuganizira mozama za mtengo ndi chitetezo chomwe mungasankhe.
Kuwerengera mtengo wa bajeti
Ngati mtengo siwomwe umakhala wolepheretsa, ndipo magwiridwe antchito ndi kukhazikika ndizofunikira kwambiri, monga zankhondo, zida zachipatala zapamwamba ndi madera ena, kukhazikika kwapamwamba komanso kukhazikika kwazinthu zamtundu wa samarium cobalt zitha kutsimikizira kugwira ntchito kodalirika kwa zida. Komabe, ngati ndikupanga zinthu zambiri za anthu wamba, kuwongolera mtengo ndikofunikira. NdFeB mankhwala akhoza bwino kuchepetsa ndalama pamene akukumana zofunika ntchito ndi otsika mtengo zopangira ndi ndalama processing.
Kufuna msika
Pazinthu zina zomwe zimafunikira kulondola kwambiri komanso kukhazikika kwa maginito, monga makina owongolera mizinga ndi zida zamaginito pazida zoyezera zamankhwala zolondola kwambiri, kulondola kwapamwamba komanso kukhazikika kwa maginito kwa zinthu za samarium cobalt ndizogwirizana kwambiri ndi zofunika. Kwa injini zamafakitale wamba, zamagetsi ogula, ndi zina zotere zomwe sizifuna kulondola kwambiri koma zimafuna mphamvu yayikulu yamaginito, mankhwala a neodymium iron boron amatha kugwira ntchitoyi bwino.
Palibe kusiyana kwakukulu pakati pa mankhwala a samarium cobalt ndi mankhwala a neodymium iron boron. Posankha zida ziwiri zabwino kwambiri za maginito, muyenera kufananiza mwatsatanetsatane. Zomwe zili pamwambazi zikuyembekeza kuthandiza aliyense kupeza zinthu zomwe zimakwaniritsa zosowa zawo!
