Ua rau muaj hlau nplaum nyob rau hauv kauv hlau yeeb nkab
Hauv cov txheej txheem vuam, DC vuam siv. Ntawm txoj kab hlau vuam, vim yog qhov loj tam sim no ntawm txoj haujlwm ntawm lub taub hau vuam, qhov chaw muaj zog sib nqus tau tshwm sim. Nyob hauv cov nyhuv ntawm qhov chaw sib nqus, lub caij sib nqus ntawm lub raj lub cev yuav zoo li tau txais lub teb chaw sib nqus nrog cov kev taw qhia ntawm sab nraud sib nqus. Thaum lub vuam hla dhau, qhov chaw magnetic maj mam txo kom txog thaum nws ploj. Vim tias qhov tshwm sim hysteresis, hauv qab lub raj lub cev thiab qhov seem ntawm cov khoom siv magnetic ntom ntom, qhov no yog qhov peb feem ntau hu ua kev nco qab.
Sib nqus kev puas tsuaj ntawm muab kauv steel yeeb nkab
Cov khoom siv hluav taws xob tsis tu ncua, pom cov duab hluav taws xob, cov duab hluav taws xob, lub teeb hluav taws xob, thiab duab xaim hluav taws xob hauv TV muaj tshuab tau pom" S" tej kab nrib pleb. Kev ntsuas kom paub tseeb. Nrog rau kev hloov pauv thiab kev txhim kho ntawm cov raj xaib steel qib ntawm xoo hluav taws xob cov duab thaij duab hluav taws xob TV, qhov kev nco ntau yog qhov tshwj xeeb tshaj plaws. Yog tias qhov kawg ntawm cov hlau nplaum muaj thiab lub nplhaib txuas nrog hauv cov raj xa dej, qee qhov tshwm sim arc thiab vuam zoo yuav tshwm sim. Txawm tias loj cuam tshuam rau qhov zoo ntawm peb tes num.
Lub kauv txoj raj AC AC degaussing hom yog txoj kev siv ntau:
1. Qhwv lub kauj nyob rau sab nraud ntawm cov yeeb nkab steel, ua kom cov kauj hla qhov sib hloov tam sim no, thiab maj mam txo qhov tam sim no ntawm qhov hloov tam sim no kom txog thaum nws poob rau xoom. Cov txiaj ntsig tau tawg: Cov yam ntxwv ntawm lub cev ntawm cov kauv steel yeeb nkab tsis hloov, tab sis lub kauv steel yeeb nkab tseem yog magnetized thaum nws ntsib qhov chaw sab nraud sib nqus.
2. Los ntawm cov txheej txheem kev kho cua sov, nws tuaj yeem raug rhuav tshem tag nrho, tab sis tom qab demagnetization, lub zog thiab kev coj nruj ntawm lub kauv raj yuav hloov, thiab sab nraud magnetic teb yuav raug ntsib yav tom ntej, thiab lub teb chaw sib nqus yuav raug tshem tawm, cov tub luam steel yeej yuav tsis muaj kev nco qab.
3. Cov txheej txheem kev kho cua sov yog ntxhib: cua sov mus rau qhov ntsuas kub yam tsis muaj oxygen, thiab tom qab ntawd maj mam txias mus rau chav sov hauv 72 teev.
