Amabanga ahlukeneyo e-Bonded NdfeB Magnet

Inkcazelo emfutshane:

I-Bonded NdFeB, eyenziwe nge-Nd2Fe14B, yimagnethi yokwenziwa.Yimagnethi eyenziwe ngokuxuba umgubo okhawulezayo weNdFeB ocinywayo kunye ne-binder ngokusebenzisa "i-compression molding" okanye "i-injection molding".Iimagnethi ezicinezelweyo ze-NdFeB kunye neodymium-i-iron boron magnets ezibunjiweyo ze-Iron boron zezona ziqhelekileyo zisetyenziswa phakathi kwazo.


Iinkcukacha zeMveliso

Iithegi zeMveliso

Ineendlela ezine zokuvelisa, eyokuqala icinezela ukubumba.(I-powder magnetic kunye ne-adhesive ixutywe ngokulinganayo kwi-volume ratio malunga ne-7: 3, iqengqeleke ukuya kubukhulu obufunekayo kwaye iqiniswe ukwenza imveliso egqityiweyo), okwesibini kukubumba inaliti.(Xuba umgubo wemagnethi kunye nesibophelelo, ubushushu kunye nokuxova, i-granulate yangaphambili, yomile, kwaye emva koko uthumele intonga yesikhokelo esijikelezayo kwigumbi lokufudumeza ukuze ufudumale, ugalele kumgodi wokubumba wokubumba ukuze ufumane imveliso egqityiweyo emva kokupholisa), eyesithathu kukubumba i-extrusion.(Ngokusisiseko iyafana nendlela yokubumba inaliti, umahluko kuphela kukuba emva kokufudumeza, iipellets zikhutshelwa kwi-mold ngokusebenzisa umngxuma wokubunjwa okuqhubekayo), kwaye okwesine kukubumba (Dibanisa i powder magnetic kunye ne-binder ngokuhambelana umlinganiselo, igranulate kunye nokongeza inani elithile le-arhente yokudibanisa, cinezela kwi-mold, qinisa kwi-120 ° ~ 150 °, kwaye ekugqibeleni ufumane imveliso egqityiweyo.)

Ukungalungi kukuba i-NdFeB yokudibanisa iqala emva kwexesha, kwaye iimpawu zemagneti zibuthathaka, ngaphandle koko, inqanaba lesicelo lincinci, kwaye idosi nayo incinci.

Iingenelo zayo kukuhlala okuphezulu, amandla aphezulu okunyanzeliswa, imveliso yamandla kamagnethi ephezulu, umlinganiselo wexabiso lokusebenza okuphezulu, ukwenza ixesha elinye ngaphandle kokucutshungulwa okwesibini, kwaye inokwenziwa kwiimagnethi ezahlukeneyo ezinokwakheka okuntsonkothileyo, ezinokunciphisa kakhulu umthamo kunye nobunzima besixhobo. imoto.Kwaye inokwenziwa nguzibuthe kulo naliphi na icala, enokuthi iququzelele ukuveliswa kweepali ezininzi okanye imagnethi engapheliyo.

Isetyenziswa ikakhulu kwizixhobo ze-automation ze-ofisi, izixhobo zombane, izixhobo ezivakalayo-ezibonwayo, izixhobo, iimotor ezincinci kunye noomatshini bokulinganisa, iimotor zokungcangcazela kweefowuni eziphathwayo, iirola zemagnethi yomshicileli, isixhobo samandla se-hard disk spindle motors HDD, ezinye iimotor ze-DC kunye nezixhobo ezizenzekelayo.
