Waqtigan xaadirka ah, walxaha magnetic joogto ah ee caadiga ah waa magnet ferrite,NdFeb magnet, SmCo magnet, Alnico magnet, magnet caag iyo wixii la mid ah.Kuwani way fududahay in la iibsado, oo leh waxqabad caadi ah (maaha qasab maaha heerarka ISO) in laga doorto.Mid kasta oo ka mid ah magnet-ka sare wuxuu leeyahay sifooyin u gaar ah iyo meelo kala duwan oo codsi ah, inta kooban ee la soo bandhigay waa sida soo socota.
Neodymium magnet
NdFeb waa magnet si weyn loo isticmaalo oo si degdeg ah u koraya.
Neodymium magnetka si weyn ayaa loo isticmaalaa laga bilaabo hal-abuurka ilaa hadda, laakiin sidoo kale in ka badan 20 sano.Sababtoo ah sifooyinka magnetic sare iyo farsamaynta sahlan, iyo qiimaha ma aha mid aad u sarreeya, sidaas darteed goobta codsiga ayaa si degdeg ah u sii ballaarinaysa.Waqtigan xaadirka ah, NdFeb ganacsiga, badeecadeeda tamarta magnetic waxay gaari kartaa 50MGOe, waana 10 jeer ferrite.
NdFeb sidoo kale waa alaab bir ah oo budada ah waxaana loo farsameeyaa si la mid ah magnet cobalt samarium.
Waqtigan xaadirka ah, NFeb heerkulkiisu sarreeyo waa ku dhawaad 180 darajo Celsius.Codsiyada qallafsan, guud ahaan waxaa lagula talinayaa inaysan ka badnayn 140 darajo Celsius.
NdFeb si fudud bay u daxalisay.Sidaa darteed, badi alaabooyinka la dhammeeyey waa in lagu dhejiyaa korantada ama dahaarka.Daawaynta caadiga ah ee dusha sare waxa ka mid ah samaynta nikkel (nikkel-copper nickel), plating zinc, plating aluminium, electrophoresis, iwm. Haddii aad ka shaqeyso deegaan xiran, waxaad sidoo kale isticmaali kartaa fosfitinta.
Sababo la xiriira sifooyinka magnetic sare ee NdFeb, marar badan, waxaa loo isticmaalaa in lagu beddelo qalabka kale ee magnetic si loo yareeyo mugga alaabta.Haddii aad isticmaasho magnets ferrite, cabbirka taleefanka gacanta ee hadda, waxaan ka baqayaa in aan ka yarayn leben kala badh.
Labada bir ee kor ku xusan waxay leeyihiin hawl-qabad ka fiican.Sidaa darteed, dulqaadka cabbirka alaabtu aad ayuu uga fiican yahay kan ferrite.Alaabooyinka guud, dulqaadku wuxuu noqon karaa (+/-) 0.05mm.
Samarium Cobalt magnet
Samarium cobalt magnets, maaddooyinka ugu muhiimsan waa samarium iyo cobalt.Sababtoo ah qiimaha alaabtu waa qaali, magnets cobalt samarium waa mid ka mid ah noocyada ugu qaalisan.
Alaabada tamarta birlabeedka ee magnets cobalt samarium waxay hadda gaari kartaa 30MGOe ama xitaa ka sareeya.Intaa waxaa dheer, magnets-ka samarium ee cobalt waa kuwo aad u xoog badan oo heerkulka u adkaysta, waxaana lagu dabaqi karaa heerkulka ilaa 350 darajo Celsius.Si ay u noqoto mid aan lagu bedeli karin codsiyo badan
Samarium cobalt magnetka waxaa iska leh alaabada birta ah ee budada ah.Soosaarayaasha guud marka loo eego cabbirka iyo qaabka baahida alaabta la dhammeeyey, waxay ku gubeen bannaan afar gees ah, ka dibna waxay isticmaalaan daab dheeman ah si ay u gooyaan cabbirka alaabta la dhammeeyey.Sababtoo ah cobalt samarium waa korantada korantada, waxaa loo gooyn karaa si toos ah.Aragti ahaan, samarium cobalt waxaa loo gooyn karaa qaab kaas oo loo jari karo si toos ah, haddii magnetization iyo cabbirka weyn aan la tixgelin.
Samarium cobalt magnets waxay leeyihiin iska caabin aad u wanaagsan oo daxalka guud ahaan uma baahna dahaadh ka-hortagga daxalka.Intaa waxaa dheer, magnets cobalt samarium waa jajaban yihiin, way adagtahay in la soo saaro alaabada cabbir yar ama derbiyo khafiif ah.
Alnico magnet
Magnet Alnico waxa uu leeyahay shubista iyo sintering laba siyaabood oo kala duwan.Wax-soo-saarka gudaha ee Alnico oo badan.Alaabta tamarta magnetic Alnico magnet waxay gaari kartaa ilaa 9MGOe, waxayna leedahay muuqaal weyn oo ah iska caabin heerkul sarreeya, heerkulka shaqada wuxuu gaari karaa 550 darajo Celsius.Si kastaba ha ahaatee, Alnico magnet waa mid aad u fudud in la demagnetize in field magnetic rogay.Haddii aad isku riixdo laba tiir oo Alnico magnet ah oo isku mid ah (laba N ama laba S ah), beerta mid ka mid ah magnets ayaa dib loo celin doonaa ama dib loo celin doonaa.Sidaa darteed, kuma habboona in lagu shaqeeyo dhul birlabeedka rogan (sida matoorka).
Alnico waxa uu leeyahay qallafsanaan aad u sarreeya waxaana la gooyn karaa silig iyo silig, laakiin qiimo sarreeya.Sahayda guud ee alaabta la dhammeeyey, waxaa jira laba nooc oo shiiditaan wanaagsan ama aan shiidi karin.
Ferrite magnet / Magnet Ceramic
Ferrite waa nooc ka mid ah walxo bir-lab la'aan ah, oo sidoo kale loo yaqaan dhoobada magnetic.Waxaan kala qaadnaa raadiyaha caadiga ah, magnet-ka gees ee ku jirana waa ferrite.
Tilmaamaha magnetic of ferrite maaha mid sarreeya, wax soo saarka tamarta magnetic hadda (mid ka mid ah xuduudaha lagu cabbiro waxqabadka magnetka) ayaa kaliya samayn kara 4MGOe wax yar ka sarreeya.Maaddadu waxay leedahay faa'iido weyn oo ah inay noqoto mid raqiis ah.Waqtigan xaadirka ah, weli si weyn ayaa looga isticmaalaa meelo badan
Ferrite waa dhoobo.Sidaa darteed, waxqabadka mashiinku wuxuu la mid yahay kuwa dhoobada.Magnet-ka Ferrite waa caaryada samaysmaya, soo baxaysa.Haddii loo baahdo in la farsameeyo, kaliya shiidi fudud ayaa la samayn karaa.
Sababtoo ah dhibka farsamaynta farsamada, sidaas awgeed qaabka ugu badan ee ferrite waa mid fudud, iyo dulqaadka cabbirku waa mid aad u weyn.Alaabooyinka qaabka labajibbaaran waa wanaagsan yihiin, waa la shiidi karaa.Wareegto, guud ahaan shiida laba diyaaradood oo keliya.Dulqaadyada kale ee cabbirka ayaa la bixiyaa sida boqolkiiba cabbirrada magac-u-yaalka ah.
Sababtoo ah magnet ferrite ayaa la isticmaalayey tobanaan sano, warshado badan ayaa leh siddo diyaarsan, labajibaaran iyo alaabooyin kale oo qaabab iyo cabbirro caadi ah si ay u doortaan.
Sababtoo ah ferrite waa walxo dhoobo ah, asal ahaan ma jiraan wax dhibaato ah oo daxalka ah.Alaabooyinka la dhammeeyey uma baahna daaweyn dusha sare ah ama dahaarka sida koronto-samaynta.
