Konke Okufuneka Ukwazi Malunga ne-'n Rating' yeNeodymium Magnets

Iimagnethi zeNeodymium, ezidunyiswa ngamandla azo angaqhelekanga kunye nokuguquguquka kwazo, ziye zaguqula amashishini ahlukeneyo ngeempawu zazo ezimangalisayo zemagnethi. Eyona nto iphambili ekuqondeni ezi magnethi yi-'n rating,' iparameter ebalulekileyo echaza amandla azo emagnethi kunye nokusebenza kwazo. Kule sikhokelo sibanzi, siza kujonga yonke into ekufuneka uyazi malunga ne-'n rating' yeiimagnethi ze-neodymium.

Yintoni kanye kanye i-'n Rating'?

I-'n rating' yemagnethi ye-neodymium ibonisa umgangatho wayo, ngakumbi imveliso yayo yamandla aphezulu. Le mveliso yamandla yindlela yokulinganisa amandla emagnethi emagnethi, echazwa kwiMegaGauss Oersteds (MGOe). Ngokusisiseko, i-'n rating' ibonisa ukuba ingakanani amandla emagnethi anokuveliswa yimagnethi.

Ukucacisa isikali se-'n Rating'

Iimagnethi zeNeodymium zilinganiswa ngokwesikali ukusukaUkusuka kwi-N35 ukuya kwi-N52 ukusuka kwi-N35 ukuya kwi-N52, kunye notshintsho olongezelelweyo olufana ne-N30, N33, kunye ne-N50M. Okukhona inani liphezulu, kokukhona imagnethi inamandla. Umzekelo, imagnethi ye-N52 inamandla kunemagnethi ye-N35. Ukongeza, izimamva ezifana no-'H,' 'SH,' kunye no-'UH' zingongezwa kwamanye amabakala ukubonisa utshintsho ekuchaseni ubushushu kunye nokunyanzelisa.

Ukuchonga Amandla kunye nokusebenza kweMagnet

I-'n rating' idlala indima ebalulekileyo ekumiseleni amandla kunye nokusebenza kweemagnethi ze-neodymium. I-'n ratings' ephezulu ibonisa iimagnethi ezinamandla amakhulu emagnethi, nto leyo eyenza zifaneleke kwizicelo ezifuna amandla apho ukusebenza okuphezulu kubalulekile. Iinjineli kunye nabayili baqwalasela i-'n rating' xa bekhetha iimagnethi zezicelo ezithile ukuqinisekisa ukusebenza kakuhle kunye nokusebenza kakuhle.

Ukuqonda Izicelo kunye neemfuno

Ukukhethwa kodidi lwemagnethi ye-neodymium kuxhomekeke kwiimfuno zesicelo. Nazi ezinye zezicelo eziqhelekileyo kunye ne-'n ratings' ehambelanayo:

Izixhobo ze-elektroniki zabathengiIimagnethi ezisetyenziswa kwiifowuni eziphathwayo, ii-headphone, kunye nezithethi zihlala ziqala kwi-N35 ukuya kwi-N50, zilungelelanisa ukusebenza kunye nobukhulu kunye nemida yobunzima.

Oomatshini BoshishinoIimoto, iijenereyitha, kunye nabahluli bemagnethi banokusebenzisa iimagnethi ezine-'n ratings' eziphezulu, ezifana ne-N45 ukuya kwi-N52, ukuphucula ukusebenza kakuhle kunye nokuthembeka.

Izixhobo zonyangoIimatshini ze-MRI kunye nezixhobo zonyango lwemagnethi zifuna iimagnethi ezineendawo ezichanekileyo zemagnethi, zihlala zisebenzisa amanqanaba afana ne-N42 ukuya kwi-N50 ukuze zisebenze kakuhle.

Umoya ovuselelekayoIiturbine zomoya kunyeIimoto zezithuthi zombane zixhomekeke kwiimagnethi ze-neodymiumnge-'n ratings' ephezulu, edla ngokuqala kwi-N45 ukuya kwi-N52, ukuvelisa amandla acocekileyo nokuqhuba uthutho oluzinzileyo.

Izinto ekufuneka uziqwalasele kunye namanyathelo okuzikhusela

Nangona iimagnethi ze-neodymium zibonelela ngokusebenza okugqwesileyo, kufuneka kuqwalaselwe izinto ezithile kunye namanyathelo okhuseleko:

UkuphathaNgenxa yamandla azo anamandla emagnethi, iimagnethi ze-neodymium zinokutsala izinto ze-ferrous kwaye zibe yingozi enkulu. Kufuneka kuqatshelwe xa kusetyenziswa ezi magnethi ukuze kuthintelwe ukwenzakala.

Ubuthathaka bobushushu: Amanye amanqanaba eemagnethi ze-neodymium abonisa iimpawu zemagnethi eziphantsi kumaqondo obushushu aphezulu. Kubalulekile ukuqwalasela imida yobushushu echaziweyo kumanqanaba onke ukuqinisekisa ukusebenza kakuhle.

Ukumelana nokugqwala: Iimagnethi zeNeodymium zichaphazeleka lula kukubola kwiindawo ezithile, ingakumbi ezo ziqulethe umswakama okanye izinto ezine-asidi. Ukusebenzisa izinto zokukhusela ezifana ne-nickel, i-zinc, okanye i-epoxy kunokunciphisa ukubola kwaye kwandise ubomi bemagnethi.

Isiphelo

I-'n rating' yeemagnethi ze-neodymium isebenza njengepharamitha esisiseko yokuqonda amandla azo emagnethi kunye nokusebenza. Ngokuchaza olu vavanyo kunye nokuqwalasela izinto ezahlukeneyo ezifana neemfuno zesicelo kunye neemeko zokusingqongileyo, iinjineli kunye nabayili banokusebenzisa amandla apheleleyo eemagnethi ze-neodymium ukuqhuba ubuchule kunye nokujongana nemingeni eyahlukeneyo kumashishini. Njengoko iteknoloji iqhubela phambili kunye nezicelo zitshintsha, ukuqonda okunzulu kwe-'n rating' kuya kuqhubeka kubalulekile ekuvuleni amandla ezi zinto zimangalisayo zemagnethi.
