Dab tsi ntawm Magnet yog siv rau cov cuab yeej Post Magnet?

Dab tsi ntawm cov hlau nplaum yog siv rau cov cuab yeej ncej hlau nplaum?

Qhov yuav tsum tau ntawm cov cuab yeej tuav hlau nplaum yog qhov yooj yim heev, uas yog, nws tuaj yeem tuav lub cuab yeej thiab ua kom lub cuab yeej tsis poob. Cov tuav riam yog cov khoom tsim nyog txhua hnub thiab yuav tsum tau txhawb nqa los tuav kev lag luam. Kev sib tw nqi tsis zoo yog ib txoj hauv kev siv los ntawm cov tub lag luam. Txhawm rau kom tsis txhob muaj cov txiaj ntsig tau txais txiaj ntsig, nws yog qhov tsim nyog los txo cov nqi ntawm cov khoom seem ntawm lub cuab yeej.

Cov khoom siv NdFeB yog tus cwj pwm los ntawm kev nyuaj thiab nkig. Tom qab magnetization, qhov nqus qhov hnyav yog ntau tshaj 600 npaug ntawm nws qhov hnyav, thiab nws yooj yim heev rau nqus thiab pob. Thiab siv tsis tau cov hlau nplaum sib nqus sib cais. Feem ntau, muaj pob ntau dua, ua rau hnav thiab tsim kua muag, thiab qhov puas tsuaj yog oxidized vim poob ntawm txheej, ua rau poob ntawm cov hlau nplaum. Ua ntej tshaj plaws, cov cuab yeej tuav hlau nplaum feem ntau yog ua los ntawm cov hlau nplaum neodymium hlau boron muaj zog, uas muaj cov yam ntxwv ntawm kev nqus dej siab thiab siab magnetism.

NdFeB yog yooj yim corroded, thiab cov txheej txheem txheej yuav tsum tau galvanized los yog npib tsib xee-plated. Ob leeg galvanized thiab npib tsib xee-plated yog nyiaj-dawb hlau, tab sis npib tsib xee-plated yog ntau ci thiab corrosion-resistant, thiab tus nqi yuav siab dua. Cov cuab yeej tuav cov hlau nplaum feem ntau ua rau hauv, yog li nws yog qhov tsim nyog xaiv galvanized thiaj li yuav txo tau cov nqi.

Yuav kom suav tau, txawm li cas los xij, N28, N33, thiab N35 yog cov hlau nplaum muaj zog, tsuav yog lawv tuav lub cuab yeej, nws yuav zoo. Lawm, qee tus neeg xaiv los ua qhov pheej hmoo thiab kho cov ntaub ntawv ntawm N28 thiab N33. Cov hlau nplaum ntawm N28 thiab N33 muaj zog heev, tab sis tsis ruaj khov heev. Demagnetization yuav pib tshwm nyob rau hauv ob lossis peb lub hlis, thiab nws yog ib nrab xyoo los ua qhov zoo. Koj puas xav txog tias thaum koj ua noj hauv chav ua noj, cov riam poob vim tsis muaj qhov nqus?

Yog li ntawd, thaum xaiv cov khoom siv hlau nplaum, nws yog ib qho tseem ceeb heev uas yuav tsum muaj cov lus ntawm lub qhov ncauj ua ntej, thiab tom qab ntawd hnub xa khoom, thiab chav tsev nqi tuaj yeem sib tham maj mam. Raws li cov lus hais mus, koj tau txais yam koj them rau.
