EPA tswj cov khoom siv hluav taws xob tiv thaiv kev ua haujlwm
Qhov chaw ua haujlwm nyob qhov twg qhov hluav taws xob qhov hluav taws xob ntawm cov khoom siv thiab cov khoom raug tswj hwm. Txhawm rau tiv thaiv cov khoom siv hluav taws xob tsis zoo (ESSD) los ntawm kev puas tsuaj rau electrostatic, thaj chaw uas tsim nyog los tiv thaiv cov ntaub ntawv thiab cov khoom siv raug siv los tsim thiab ua kom tiav, feem ntau muaj cov cim qhia tseeb los tiv thaiv kev tiv thaiv. Cov neeg ua hauj lwm nkag mus rau thaj chaw ua haujlwm tawm tsam yuav tsum ua raws li txoj cai kev ua haujlwm los tiv thaiv kev ua haujlwm. Kuj tseem hu ua ECA (ESD tswj cheeb tsam)
Hauv kev tsim cov khoom siv hluav taws xob dav dav, kev sib dhos thiab cov chaw tu, ntau yam hluav taws xob tsim hluav taws xob thiab cov hluav taws xob hluav taws xob tau tsim los ntawm lawv yog qhov tshwm sim ntau. Cov hluav taws xob zoo li qub hluav taws xob thiab cov hluav taws xob hluav taws xob tsim los ntawm lawv yuav ua kev puas tsuaj rau cov khoom siv hluav taws xob tsis zoo. Yog li, lub tshuab electrostatic rhiab yuav tsum tiv thaiv thaum tag nrho kev siv.
Hauv kev khaws cia thiab hloov txheej txheem ntawm cov khoom siv hluav taws xob tsis yooj yim, cov thawv ntim uas muaj qhov thaiv nrog kev ua haujlwm tuaj yeem muab cov kev tiv thaiv tsim nyog. Txawm li cas los xij, tseem muaj kev ua haujlwm sab nraud lub thawv thaiv rau cov khoom siv hluav taws xob tsis zoo. Hauv qhov no, electrostatic rhiab khoom siv tau zoo los ua kev puas tsuaj. Yog li, nws yog qhov yuav tsum tau muab thaj chaw ua haujlwm kom nyab xeeb. Cov Khoom Siv Ua Haujlwm Tshaj Tawm (EPA) yog tsim los rau lub hom phiaj no. Txhawm rau kom muaj kev tiv thaiv zoo li qub ntawm kev ua haujlwm, nws yuav tsum ua kom tau raws li cov hauv qab no:
⑴ Tag nrho cov khoom siv hluav taws xob hauv qhov chaw tiv thaiv zoo li qub yuav tsum ua raws li cov khoom siv hluav taws xob tsis zoo.
⑵ Ib qho kev ua haujlwm ntawm electrostatic rhiab khoom siv sab nraud tiv thaiv lub xeev (sab nraum Faraday tawb) yuav tsum tau nqa tawm hauv thaj chaw ua haujlwm tawm tsam.
⑶ Cov khoom siv hluav taws xob tsis zoo uas thauj hauv thaj chaw tsis muaj chaw nyob ntawm thaj chaw tiv thaiv kev ua haujlwm yuav tsum nyob hauv lub xeev tiv thaiv kev nyab xeeb.
Kev tsim qauv ntawm thaj chaw ua haujlwm tiv thaiv kev ua haujlwm yuav tsum muaj peev xwm xyuas kom meej tias cov khoom siv hluav taws xob tsis yooj yim los kov lub plhaub hlau plhaub ntawm cov khoom siv.
Is Nws yog txwv tsis pub tso cov khoom zoo li qub uas tsis tsim nyog rau kev ua haujlwm hauv thaj chaw tiv thaiv kev ua haujlwm, xws li lub hnab yas, thawv, txau, siv tawv, siv ntawv, ntawv sau, ntawv ntim khoom, thiab khoom siv rau tus kheej uas tsis kho nrog tiv thaiv kev tiv thaiv. zoo li qub kev kho mob. Cov ntaub ntawv no yuav tsum muaj 30 Cm sab saud.
⑹ Tag nrho cov tshuaj ntxuav kab mob, cov kuab tshuaj, cov khoom siv txheej, aerosols thiab lwm cov khoom siv coj los siv ua haujlwm yuav tsum tau txais kev pom zoo los ntawm tus neeg ua tus tswj hwm zoo li qub.
2 EPA qhov faib thiab ib puag ncig xav tau
2.1 EPA faib
Qhov kev faib tawm ntawm thaj chaw tiv thaiv zoo li qub yog nyob ntawm seb puas muaj cov khoom lag luam zoo li qub hauv cheeb tsam raws li cov txheej txheem. Raws li ntev li cov khoom zoo li qub yuav tshwm sim, nws yuav tsum tau txhais tias yog thaj chaw tiv thaiv zoo li qub, txwv tsis pub nws tuaj yeem txhais tias yog thaj chaw tsis muaj kev tiv thaiv. Tus ciam ntawm thaj tsam tiv thaiv zoo li qub yog txiav txim siab los ntawm cov tuam tsev txheej txheem thiab tus neeg ua haujlwm hauv thaj tsam tiv thaiv zoo li qub.
Thaj chaw ua haujlwm tiv thaiv zoo li qub (EPA) suav nrog tab sis tsis txwv rau thaj chaw hauv qab no: thaj chaw tshuaj ntsuam IQC, thaj chaw ua haujlwm thiab tshuaj xyuas thaj chaw, thaj chaw kuaj thiab kuaj thaj chaw, cov khoom sib dhos thiab thaj chaw soj ntsuam, tag nrho cov tshuab sib dhos thiab cov chaw ua haujlwm, thaj chaw tu , kuaj thaj tsam, tally thaj chaw, cov khoom sib txuas thiab thaj chaw faib khoom, thaj chaw khaws cia, thiab lwm yam.
EPA yuav tsum tau faib raws li qib electrostatic qhov kev paub ntawm cov khoom ua haujlwm hauv thaj chaw thiab qhov kev pheej hmoo ntawm electrostatic tawm haujlwm thaum tsim khoom. Saib raws li cov cai hauv seem 3.1.
2.2 EPA' s yooj yim ib puag ncig xav tau
Thaum tsim qauv ntawm EPA ib puag ncig, cov hauv qab no yuav tsum tau ua raws li qhov ua kom tau raws li kev xav tau ntawm kev tiv thaiv electrostatic:
Txwv tsis pub muaj kev sib txuam ntawm cov nqi hluav taws xob zoo li qub thiab tiam ntawm qhov hluav taws xob zoo li qub.
Muaj kev nyab xeeb, sai sai thiab muaj txiaj ntsig tshem tawm tus nqi tsim hluav taws xob zoo li qub.
Txiav txim siab qhov ntau ntawm electrostatic tiv thaiv uas yuav tsum tau ua tiav. Piv txwv, qhov tseeb dui tus nqi ntawm electrostatic voltage hauv yi-theem EPA yuav tsum tsawg dua 100V.
Yog li ntawv, EPA yuav tsum muaj cov cai ib puag ncig hauv qab no:
⑴ Ua kom thaj tsam muaj kev thaj yeeb nyab xeeb thiab ntawv ceeb toom tiv thaiv zoo li qub.
Tshaj tawm tau zoo rau txhua tus neeg ua yeeb yam hauv thaj chaw, suav nrog cov neeg ua haujlwm.
Tshem tawm txhua qhov tsis tsim nyog ntawm hluav taws xob zoo li qub.
⑷ Siv lub ntsiab cai 12-nti, uas yog, ESSD lub cuab yeej yuav tsum nyob yam tsawg 30 cm ntawm qhov muaj fais fab zoo li qub.
Nyob rau tib lub sijhawm, kev ua los tiv thaiv kev ua haujlwm ntawm cov puag ncig ib puag ncig hauv qab no yuav tsum raug xam tias:
Antistatic wallpaper yuav tsum siv cov ntaub qhwv phab ntsa. Feem ntau, cov xim pleev xim plaster lossis cov xim pleev xim rau cov phab ntsa tso cai, thiab cov khoom yas zoo tib yam raug txwv.
Cov khoom siv hauv qab nthab yuav tsum ua cov ntaub ntawv antistatic. Feem ntau, gypsum board khoom tso cai, thiab cov khoom yas zoo tib yam raug txwv.
Cov ntaub thaiv qhov rooj, kab hlau rhuav, thiab thaj chaw sib cais siv nyob rau hauv thaj chaw ua haujlwm yuav tsum ua cov khoom siv los tiv thaiv zoo li qub, thiab tus nqi saum npoo yuav tsum tsawg dua 1 × 1011Ω. Txwv tsis pub siv cov khoom siv yas thiab cov tshuaj fiber ntau.
