Jihada magnetization ee magnetka waxaa lagu go'aamiyaa inta lagu jiro habka wax-soo-saarka. Jihada magnetization ee alaabta la dhammeeyey lama beddeli karo. Fadlan hubi inaad qeexdo jihada magnetization-ka ee la rabo ee alaabta.
Jihada magnetization-ka caadiga ah ee hadda ayaa lagu muujiyay sawirka hoose:
Jihada Magnetization waa tillaabada ugu horreysa ee agabka birta ee joogtada ah sida boron-ka birta dhulka dhifka ah iyo magnets-ka cobalt ee samarium si loo helo magnetismka. Waxay ka dhigan tahay tiirarka Waqooyiga iyo Koonfurta ee magnet ama qayb birlab ah. Astaamaha birlabeedka ee agabka birlabeedka joogtada ah waxa inta badan laga soo min guuriyay dhismooyinkooda crystal magnetizable si fudud. Burburintan, magnet-ku wuxuu heli karaa sifooyin birlab aad u sarreeya oo hoos yimaada ficilka goob xoog leh oo dibadda ah, iyo sifooyinka magnetic-ka ma baabi'i doono ka dib marka goobta birta ah ee dibadda la waayo.
Ma la bedeli karaa jihada magnetization-ka ee magnetka?
Marka loo eego jihada magnetization-ka, qalabka birlabku wuxuu u qaybsan yahay laba qaybood: magnets isotropic iyo magnets anisotropic. Sida magacaba ka muuqata:
Magnets isotropic waxay leeyihiin sifooyin magnetic isku mid ah jiho kasta waxayna soo jiidanayaan si aan kala sooc lahayn.
Qalabka magnetka joogtada ah ee Anisotropic waxay leeyihiin sifooyin birlab kala duwan oo jihooyin kala duwan ah, iyo jihada ay ku heli karaan guryaha ugu wanaagsan / xoogga badan ee magnetic waxaa loo yaqaan jihada jihada ee alaabta magnetic joogto ah.
Tignoolajiyada hanuuninta waa hab lagama maarmaanka u ah soo saarista walxaha magnetka joogtada ah ee anisotropic. Magnet-yada cusub waa anisotropic. Jihaynta goobta magnetic ee budada waa mid ka mid ah teknoolojiyadda muhiimka ah ee soo saarista wax-qabadka sare ee magnets NdFeB. Sintered NdFeB guud ahaan waxaa lagu cadaadiyaa jihada magnetic field, markaa jihada jihada ayaa loo baahan yahay in la go'aamiyo ka hor wax soo saarka, taas oo ah jihada magnetization-ka ee la doorbido. Marka magnet neodymium la sameeyo, ma beddeli karto jihada magnetization. Haddii la ogaado in jihada magnetization-ka ay khaldan tahay, magnetku wuxuu u baahan yahay in dib loo habeeyo.
Dahaarka iyo Duubista
Sababo la xiriira iska caabinta daxalka ee NdFeB magnets, korantada guud ahaan ayaa loo baahan yahay si looga hortago daxalka. Markaas su'aashu waxay timaaddaa, maxaan ku saxaaraa magnets-ka? Waa maxay dajinta ugu fiican? Marka la eego saamaynta ugu fiican ee daahan NdFeB ee dusha sare, marka hore, waa in aan ogaano NdFeB midkee lagu dhejin karaa?
Waa maxay dahaarka guud ee magnets ndFeB?
NdFeB daahan magnet xoog leh guud ahaan waa nikkel, zinc, resin epoxy iyo wixii la mid ah. Iyadoo ku xiran koronto-siinta, midabka dusha magnetka ayaa sidoo kale noqon doona mid ka duwan, iyo wakhtiga kaydinta ayaa sidoo kale kala duwanaan doona wakhti dheer.
Saamaynta NI, ZN, resin epoxy, iyo dahaarka PARYLENE-C ee sifooyinka magnetic ee magnets NdFeB ee saddexda xal ayaa la bartay marka la barbardhigo. Natiijooyinku waxay muujiyeen in: jawiga acid, alkali, iyo cusbada, dahaarka alaabta polymerka Saamaynta ilaalinta ee magnetka ayaa ah tan ugu fiican, xajinta epoxy waa mid liidata, daboolka NI waa labaad, iyo daahan ZN waa mid liidata:
Zinc: Dusha sare waxay u egtahay caddaan qalin ah, waxaa la isticmaali karaa 12-48 saacadood oo buufin milix ah, waxaa loo isticmaali karaa qaar ka mid ah isku-xidhka xabagta, (sida xabagta AB) waxaa lagu kaydin karaa laba ilaa shan sano haddii ay koronto ku jirto.
Nickel: wuxuu u eg yahay bir aan bir lahayn, dusha sare waa ay adag tahay in hawada lagu shubo, muuqaalkuna waa wanaagsan yahay, dhalaalidduna waa wanaagsan tahay, koronto-samaynta waxay ku gudbi kartaa tijaabada buufinta cusbada 12-72 saacadood. Khasaaradeedu waa in aan loo isticmaali karin in lagu xidho koollada qaarkood, taas oo keeni doonta in dahaarka uu ka dhaco. Dedeji oksaydhka, hadda habka nikkel-copper-nickel electroplating inta badan waxaa lagu isticmaalaa suuqa 120-200 saacadood oo buufin milix ah.
