Koj puas tau hnov dua ntawm qhov chaw tawg paj? Yog hais tias koj muaj, ces koj puas paub nyob rau hauv cov xwm txheej dab tsi?
1: Magnets demagnetize tom qab txhaj tshuaj, qhov tsawg kawg nkaus kub taub hau ntawm N Series NdFeB yog 80 ℃, thiab qee zaus kev txhaj tshuaj yog li ntawm 120 ℃, yog li ib lub sij hawm luv luv ntawm 2 mus rau 3 feeb ntawm kev txhaj tshuaj yuav ua rau ib nrab ntawm cov pa tawg.
2: Cov hlau nplaum yuav ua rau tom qab kub nyhav tawm hauv cov hlau nplaum.Lub tuav cov iav fiber ntau siv rau kev kub ceev, thiab qhov kub siab tshaj 150 ℃.
3: Cov hlau nplaum yuav ua rau tom qab sov hauv qhov cub.
4: Sib nqus cov ntaub ntawv muaj ntau impurities uas ua rau tsis muaj zog magnetism. Qhov no yog qhov tshwm sim ntawm feem ntau tsis txaus ua lag luam. Piv txwv, cov neeg muas zaub xav kom N35 series, tab sis cov tuam txhab tsis muaj kev ntseeg xaiv cov khoom ntawm tus nqi qis, zoo li N28, N33. Cov neeg muas zaub yuav tsum tsis txhob xav tias yuav pom tau, vim hais tias yog qhov nyiaj nce mus txog 30K, nws yuav siv sijhawm ntev los ntsuas. (demagnetization yuav tshwm sim nyob rau hauv 6 lub hlis, txawm tias ob lub hlis ua tau). Li ntawd, tus txhim khu kev qha yog qhov tseem ceeb heev. GME tuaj yeem yog koj tus khub ncaj ncees.
5: Tej yam yuav tshwm sim nyob rau hauv kev sib tawg, xws li kev cuam tshuam cov kev kub ntxhov, thiab ntxiv rau. Li ntawd, cov hlau nplaum yuav tsum tau ceev faj thaum lub tsheb npav.
6: Cov ntaub ntawv muaj lanthanum uas yuav ua rau muaj hlau nplaum.
7: Qhov chaw muaj hlau nplua nuj ua rau cov hlau nplaum ploj lossis hloov N / S ncej Qhov no yuav tshwm sim nrog kev pabcuam magnetizer / demagnetizer.
Tag nrho hauv txhua qhov, 90% ntawm cov txheej xwm ntawm qhov kev sib txuas lus tau muab coj los ua ke raws li nram no:
Kub siab
Unqualified raw khoom
Qhov muaj feem cuam tshuam heev
High magnetic chaw
