Kev thauj mus los hauv huab cua muaj qee yam tshwj xeeb. Txhawm rau kom muaj kev nyab xeeb, ob leeg tib neeg thiab cov khoom thauj yuav tsum tau kuaj xyuas kev nyab xeeb ua ntej nce tsheb. Yog tias koj nqa cov khoom sib nqus, xws li neodymium hlau boron muaj zog hlau nplaum, thaum caij davhlau, lossis cov neeg siv khoom nrawm thiab xav kom cov khoom xa tuaj los ntawm huab cua, peb puas tuaj yeem nqa cov hlau nplaum ntawm lub dav hlau lub sijhawm no?
Txij li thaum tsis muaj zog stray magnetic teb tuaj yeem cuam tshuam nrog lub dav hlau navigation systems thiab tswj cov teeb liab, International Air Transport Association (IATA) faib cov khoom sib nqus sib nqus raws li qeb 9 cov khoom txaus ntshai thiab yuav tsum tau txwv thaum sau thiab thauj. Yog li ntawd, qee qhov kev thauj khoom huab cua uas muaj cov khoom sib nqus tam sim no yuav tsum tau kuaj cov hlau nplaum kom ntseeg tau tias lub dav hlau zoo li qub. Cov ntaub ntawv sib nqus, cov ntaub ntawv suab thiab lwm yam khoom siv uas muaj cov khoom siv sib nqus yuav tsum tau kuaj xyuas cov hlau nplaum.
Huab cua freight qauv
Raws li cov kev cai cuam tshuam ntawm IATA902: Yog tias qhov siab tshaj plaws magnetic teb lub zog ntsuas 2.1m deb ntawm cov khoom raug ntsuas tsis pub tshaj 0.159A/m (200nT, uas yog sib npaug rau 2mGs=0.002Gs), cov khoom tsis txwv raws li cov khoom sib nqus thiab tuaj yeem siv los ua kev thauj khoom dav dav. Yog tias qhov siab tshaj plaws magnetic teb lub zog ntsuas ntawm qhov deb ntawm 2.1m los ntawm cov khoom raug ntsuas ntau tshaj 0.159A / m, tab sis ib qho kev sib nqus sib nqus ntawm qhov deb ntawm 4.6m los ntawm qhov chaw ntawm qhov khoom ntsuas yog tsawg dua 0.418A / m. , cov khoom tuaj yeem lees paub tias yog cov khoom txaus ntshai. Yog tias qhov kev xav tau no tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, cov khoom raug txwv tsis pub thauj los ntawm huab cua.
Yuav ua li cas kom tau raws li cov qauv huab cua freight
Yuav kom ua tau raws li cov kev cai saum toj no rau kev thauj huab cua, cov hlau nplaum xa los ntawm huab cua yuav tsum tau demagnetized. Txawm hais tias nws yog hu ua demagnetization, nws tsis yog txheej txheem demagnetization rau cov hlau nplaum. Hloov chaw, lub ntim yog siv los xyuas kom meej tias cov hlau nplaum tso tawm los ntawm lub pob ua tau raws li lub teb chaws aviation kev nyab xeeb kev thauj mus los. Shielding ntim feem ntau yog siv cov khoom sib nqus permeability siab, xws li cov ntawv txias dov, cov ntawv galvanized, thiab lwm yam. Yog tias cov khoom sib nqus loj, nws yuav tsum tau ntim rau hauv ob peb txheej. Qhov sib nqus permeability ntawm cov khoom sib nqus permeability siab heev. Raws li Faraday hluav taws xob lub hauv paus ntsiab lus, lub magnetic teb feem ntau circulates nyob rau hauv lub thawv tom qab ntim, thiab heev me ntsis ntws tawm. Ntim rau hauv cartons los yog ntoo thawv sab nraum lub shielded ntim.
Magnetic detection
Cov tuam txhab lag luam lossis cov tuam txhab logistics uas nqa cov khoom sib nqus yuav xav kom cov neeg siv khoom siv cov khoom siv hlau nplaum thiab muab "Air Transport Conditions Identification Report" los xyuas kom meej lub dav hlau ib txwm muaj. Kev ntsuas huab cua feem ntau tuaj yeem tsuas yog muab los ntawm cov tuam txhab kev ntsuam xyuas cov kws tshaj lij uas tau lees paub los ntawm kev tswj hwm pej xeem aviation hauv lub tebchaws, thiab feem ntau yuav tsum xa cov qauv mus rau lub tuam txhab ntsuas kev ntsuas kev tshaj lij thiab tom qab ntawd tshaj tawm tsab ntawv ceeb toom. Yog tias nws tsis yooj yim rau xa cov qauv, cov kws tshaj lij los ntawm lub tuam txhab ntsuam xyuas yuav ua qhov kev sim ntawm qhov chaw thiab tom qab ntawd muab daim ntawv ntsuam xyuas. Lub sijhawm siv tau ntawm daim ntawv txheeb xyuas feem ntau yog rau xyoo tam sim no. Tom qab lub xyoo tshiab, nws feem ntau yuav tsum tau rov ua dua.
Thaum kuaj cov hlau nplaum, cov neeg siv khoom yuav tsum ntim cov khoom raws li cov kev xav tau ntawm kev thauj mus los. Kev sim yuav tsis ua rau lub ntim ntawm cov khoom puas. Nyob rau hauv txoj cai, cov khoom tsis yog unpacked rau kev kuaj. Lub stray magnetic teb tsuas yog kuaj ntawm 6 sab ntawm txhua daim ntawm cov khoom. Yog tias cov khoom ua tsis tau qhov kev soj ntsuam sib nqus, yuav tsum tau them nyiaj tshwj xeeb. Ua ntej, nrog kev pom zoo los ntawm cov neeg siv khoom, cov neeg ua haujlwm soj ntsuam cov hlau nplaum yuav raug tso siab rau kom ntim cov khoom thiab tshuaj xyuas lawv, thiab tom qab ntawd ua cov lus qhia tsim nyog raws li qhov xwm txheej tshwj xeeb. Yog tias cov ntaub thaiv npog tuaj yeem ua tau raws li qhov xav tau ntawm kev thauj mus los hauv huab cua, cov khoom yuav raug tiv thaiv raws li tus neeg siv khoom tso siab, thiab cov nqi cuam tshuam yuav raug them.
