Intshayelelo kwiZixhobo zeMagnetic ezomelele
Izixhobo ezinamandla zemagneti, ngakumbi izixhobo zemagneti ezisisigxina ezinjenge-neodymium iron boron (NdFeB) kunye ne-samarium cobalt (SmCo), zisetyenziswe ngokubanzi kushishino lwanamhlanje ngenxa yamandla azo anamandla emagnethi kunye nokusebenza okugqwesileyo. Ukusuka kwiimotor ukuya kwizixhobo zonyango, ukusuka kwi-elektroniki yabathengi ukuya kwi-aerospace, ezi zixhobo zidlala indima ebalulekileyo. Nangona izixhobo ezinamandla zemagneti zisetyenziswa kwiindawo ezininzi, ubungozi bazo obunokubakho abunakuhoywa. Masifunde indlela eyomeleleyo ngayo imathiriyeli yemagnethi, siqonde ngcono iingozi ezinokubakho, kwaye sizithintele ngcono.
Indlela ezomeleleyo ngayo izinto zemagnethi ezizalwa ngayo
1. Ukulungiselela izinto ezikrwada: Inyathelo lokuqala ekuveliseni izinto ezomeleleyo magnetic kukulungisa imathiriyeli ekrwada. Kwi-NdFeB, ezona zixhobo ziphambili zibandakanya i-neodymium, i-iron, i-boron kunye nezinye izinto zokulandelela ezifana ne-dysprosium kunye ne-praseodymium. Iimathiriyeli ekrwada kufuneka zihlolwe ngokungqongqo kwaye zicutshungulwe ukuze kuqinisekiswe ukuba ukucoceka kunye nomlinganiselo wokubunjwa kuyahlangabezana neemfuno.
2. Ukunyibilika: Izinto ezilungisiweyo ezilungisiweyo zifakwe kwi-vacuum induction furnace ukuze inyibilike ukwenza i-alloy. Kule nkqubo, ulawulo lobushushu lubaluleke kakhulu kwaye ngokuqhelekileyo kufuneka luqhutywe kwiqondo lokushisa elingaphezulu kwe-1000 ° C. I-alloy liquid smelted iya kugalelwa kwi-mold ukuze ipholile kwaye yenze i-ingot.
3.Ukutyumza kunye nokusila: I-ingot epholileyo kufuneka iqhekezwe ibe ngamaqhekeza amancinci ngesityuli kwaye iphinde iculwe ibe ngumgubo ocolekileyo ngebhola. Ubungakanani be-particle ye powder ecocekileyo ichaphazela ngokuthe ngqo umgangatho wenkqubo elandelayo, ngoko eli nyathelo libaluleke kakhulu.
4. Uqhelaniso lucinezela: Umgubo ocolekileyo ulayishwa kwi-mold kwaye emva koko ulungelelaniswe kwaye ucinezele phantsi kwesenzo sentsimi yamagnetic enamandla. Oku kuqinisekisa ukuba isalathiso se-magnetic powder particles sihambelana, ngaloo ndlela siphucula iimpawu zamagnetic zemveliso yokugqibela. Imveliso emva koxinzelelo olujoliswe kuyo ibizwa ngokuba "ngumzimba oluhlaza".
5. Sintering: Umzimba oluhlaza ufakwe kwisithando somlilo kwaye ufakwe kwiqondo lokushisa eliphezulu (malunga ne-1000 ° C-1100 ° C) ukuqinisa kunye nokwenza imagnethi enzima. Ngexesha lenkqubo ye-sintering, izinto eziphathekayo zihamba ngotshintsho olunzima lomzimba kunye neekhemikhali, kwaye ekugqibeleni lwenza imveliso egqityiweyo eneempawu eziphezulu zamagnetic.
6. Ukucutshungulwa kunye nonyango lwangaphezulu: Imagnethi ene-sintered nayo ifuna ukusikwa, ipolishwe kunye nokunye ukusetyenzwa koomatshini ukufezekisa imilo kunye nobukhulu obufunekayo. Ukuze uthintele umazibuthe kwi-oxidation okanye ukubola ngexesha lokusetyenziswa, umaleko okhuselayo onjenge-nickel, i-zinc okanye i-epoxy resin idla ngokugqunywa kumphezulu wayo.
7. Imagnethi: Inyathelo lokugqibela kukwenza umazibuthe ukuze unike iimpawu zemagnethi ezifunekayo. I-Magnetization idla ngokuqhutyelwa kwisixhobo esikhethekileyo semagneti, kusetyenziswa indawo eyomeleleyo yamagnetic ukwenza imimandla yemagnethi kwimagnethi ihambelane.
Ubungozi bemagnethi eyomeleleyo
Ukubulawa kwemathiriyeli eyomeleleyo yemagnethi ibonakaliswa ikakhulu kule miba ilandelayo:
1. Impembelelo kwizixhobo zombane: Izinto ezinamandla zamagnetic zinokuphazamisana nokusebenza kwezixhobo zombane, ngakumbi ezo zixhomekeke kwi-sensors magnetic. Ngokomzekelo, iifowuni eziphathwayo, ii-hard drives zekhompyutha, ii-credit cards, njl. njl
2.Impembelelo kumzimba womntu: Nangona izinto eziqinileyo zemagneti zingenzi ingozi ebulalayo ngokuthe ngqo kumzimba womntu, zinokubangela intlungu yendawo okanye ukungahambi kakuhle xa ziginyiwe okanye zidibene nolusu. Ukongeza, izinto eziqinileyo zemagneti zinokutsala izinto zentsimbi ezikufutshane kwaye zibangele ukulimala ngengozi.
3.Impembelelo kwezinye izinto zemagnethi: Izixhobo ezinamandla zemagneti zinokutsala kwaye zihambise ezinye izinto ezinobubuthe, ezinokubangela ukuba izinto ezinzima ziwe okanye zonakaliswe izixhobo xa zingaphathwanga kakuhle. Ngoko ke, xa usebenzisa izinto ezinamandla zamagnetic, amanyathelo afanelekileyo okhuseleko kufuneka athathwe ukuphepha ingozi engeyomfuneko.
4.Impembelelo kwizixhobo zoomatshini: Kwezinye iimeko, imathiriyeli yemagnethi eyomeleleyo inokubhengeza iinxalenye zentsimbi kwisixhobo somatshini, ibangele ukusilela kwesixhobo okanye ukuvalwa. Esi siphumo sibi kakhulu kwizixhobo ezichanekileyo kunye nezixhobo zonyango.
Ukuthintela njani iziphumo zemagnethi eyomeleleyo
1. Gcina umgama wakho: Gcina imathiriyeli eyomeleleyo yemagnethi kude nezixhobo zombane, amakhadi etyala kunye nezinye izinto ezinovakalelo.
2. Amanyathelo okukhusela: Nxiba izixhobo ezifanelekileyo zokukhusela xa uphethe imathiriyeli eyomeleleyo yemagnethi kwaye uphephe ukudibana ngokuthe ngqo nolusu.
3. Imfundo nezilumkiso: Fundisa abantwana ukuba bangadlali ngezinto zokudlala ezinamandla zemagnethi kwaye uqinisekise ukuba bayabuqonda ubungozi obunokubakho.
4. Isikhokelo sobungcali: Kwiimeko zonyango, qinisekisa ukuba izigulane kunye nabasebenzi bayayiqonda imimiselo yokhuseleko kwizinto eziqinileyo zamagnetic kwaye bathathe amanyathelo afanelekileyo okukhusela.
5. Ukugcinwa kunye nokuthutha: Izinto ezinamandla zamagnetic kufuneka zigcinwe kwiibhokisi ezikhethekileyo kwaye zikhuselwe ngokufanelekileyo ngexesha lokuthutha ukukhusela ukudibanisa nezinye izinto.
Inkqubo yokuvelisa izinto eziqinileyo zemagnethi yinkqubo entsonkothileyo nethambileyo ebandakanya amanyathelo amaninzi kunye neendlela zobuchwephesha obuchwepheshile. Ukuqonda inkqubo yayo yokuvelisa kusinceda siqonde ngcono kwaye sisebenzise ezi zixhobo. Kwangaxeshanye, kufuneka silumkele ubungozi obunokubakho bezinto ezimandla zemagnethi kwaye sithathe amanyathelo asebenzayo okukhusela ukuqinisekisa ukhuseleko lwethu.
