Lub luag haujlwm ntawm kev tiv thaiv ntawm txhua yam
Txoj haujlwm ua haujlwm zoo li qub yog hais txog kev hnav tsoos hnav uas muaj cov ntaub los tiv thaiv los ntawm cov ntaub qhwv los tiv thaiv kom tsis txhob muaj hluav taws xob los ntawm cov ris tsho.
Cov ntaub npog tiv thaiv yog cov ntaub npuag tau los ntawm cov khoom siv hluav taws xob los yog cov tshuaj tua hluavtaws antistatic hluavtaws los yog sib xyaw ntawm ob qhov sib npaug los yog sib npaug ntawm lub cev. Txoj kev siv fiber ntau yog ib lub sij hawm dav dav rau cov khoom siv los yog cov khoom siv subconductive uas siv hlau los yog cov khoom siv organic los sis tag nrho, thiab muaj lub cev ntim ntawm θ 104 ~ 109 Ω / cm. Raws li kev faib tawm ntawm cov khoom siv hluav taws xob hauv cov fiber ntau, cov khoom siv hluav taws xob tuaj yeem raug faib ua peb hom: ib qho kev tivthaiv tivthaiv hom, ib yam khoom tivthaiv npog hom, thiab kev tivthaiv kev tivthaiv. Nyob rau tam sim no, feem ntau ntawm cov ntaub thaiv los tiv thaiv zoo li qub los ntawm cov qauv fais fab, tshwj xeeb tshaj yog cov kev tivthaiv tivthaiv sib xyaw hom, uas yog, cov kua hluav taws xob feem ntau siv feem ntau.
Ib qho kev ua hauj lwm uas siv antistatic ua los ntawm cov fibers hluav taws xob yog ntxiv rau cov tshuaj fiber ntau ntaub, thiab lub zog faib raws li ob lub tswv yim ntawm cov nqi dej ntub tawm thiab kev tsis tuaj yeem. Thaum grounded, hluav taws xob ntawm hluav taws xob nyob rau ntawm lub npog yog neutralized los ntawm corona paug ntawm lub fibers hluav taws xob, thiab tuaj yeem raug muab mus rau hauv av ntawm lub fibers conductive; thaum tsis tau grounded, qhov hluav taws xob yog tso tawm los ntawm lub plawv tsis muaj zog ntawm cov fibers hluav taws xob.
Kev xyaum tau pom tias cov haujlwm ua haujlwm zoo li qub yuav pab tau kom muaj hluav taws xob nyob hauv kev hnav khaub ncaws thiab tshem tawm los yog txo kom tsis txhob muaj kab mob electrostatic paug. Thaum tib neeg lub cev ua ntau yam kev ua si, qhov nqi hluav taws xob zoo li qub ntawm cov khaub ncaws zoo heev tshaj qhov hluav taws xob paug hluav taws xob paim hluav taws xob ntau ntawm cov electrostatic rhiab, thiab cov cuab yeej ua kom raug puas ntsoog thaum kov lossis nkag mus rau cov khoom no. Nws kuj yuav tsum tau taw qhia tias nws feem ntau ntseeg tias hnav ib txoj hauj lwm paj rwb yuav thaiv kev tiv thaiv ntawm kev hnav khaub ncaws li qub thiab yog li ntawd muaj kev ruaj ntseg. Qhov pom tseeb yog ib qho-ib tog, tsuas yog thaum tus txheeb ze ntawm huab cua siab siab tshaj 50%; thiab thaum twg cov txheeb ze ntawm lub cev qis qis dua, tus nqi ntawm cov khoom siv ntshiab ntawm cov khoom ntshiab yog nce. Cov kev kuaj pom tau hais tias nyob ntawm ib tus txheeb ze ntawm qhov qis tshaj 30%, qhov khoom ntawm paj rwb ntaub yog piv rau cov polyester; thiab thaum twg tus txheeb ze cov av qis dua qis dua 20%, qhov paj ntaub ntawm paj rwb ntaub yog qhov siab tshaj qhov uas qee cov tshuaj ntaub. Yog li ntawd, nyob rau hauv ib qho kev nyab xeeb qhuav, nws tsis xav kom siv cov khoom siv paj rwb kom tshem tawm cov khoom xiam oob qhab ntawm txhua yam. Rau cov nqe lus saum toj no, thiaj li yuav tiv thaiv kom tsis txhob muaj hluav taws xob hluav taws xob hauv lub cev tib neeg lub cev, tus neeg tsav tsheb yuav tsum tau hnav hom khaub ncaws ua haujlwm zoo li qub.
