Anti-static khau paub
Hluav taws xob ua haujlwm tiv thaiv khau yog khau tiv thaiv kev tiv thaiv taw rau hauv cov khoom siv tiv thaiv tus kheej, nrog rau cov khau tiv thaiv zoo li qub, cov khau hluav taws xob thiab cov khau hluav taws xob, uas tuaj yeem tiv thaiv kev puas tsuaj zoo li qub thiab hluav taws xob poob siab.
Kev puas tsuaj ntawm hluav taws xob static rau tib neeg lub cev
Kev puas tsuaj ntawm hluav taws xob zoo li qub rau tib neeg lub cev yog: ua rau muaj kev puas siab puas ntsws teeb meem, ua rau muaj kev ntshai, ua rau muaj xwm txheej, thiab tawv nqaij kub hnyiab thiab dermatitis vim electrostatic shock. Qhov teeb meem tseem ceeb ntawm hluav taws xob zoo li qub yog tias muaj hluav taws kub thiab tawg tawg ua rau muaj kev phom sij rau cov neeg ua haujlwm lub neej thiab ua rau muaj kev puas tsuaj loj hauv cov chaw tsim khoom.
Hluav taws xob poob siab yog ib qho kev huam yuaj tshwm sim thiab tuaj yeem muab faib ua hluav taws xob tiv tauj thiab tsis sib cuag hluav taws xob. Tus qub yog tam sim no raug mob, uas tuaj yeem ua rau cov ntaub so ntswg sab hauv ntawm tib neeg lub cev, xws li lub plawv, ua pa, thiab lub paj hlwb. Cov neeg sib zog muaj qhov hnov ntawm acupuncture thiab percussion, thiab muaj kev tshee, convulsions, ntshav siab, thiab arrhythmia mus txog rau coma; Thaum mob hnyav, ventricular fibrillation, plawv nres, ua pa nres, thiab tuag yuav tshwm sim. Cov tom kawg yog feem ntau arc raug mob, uas yog tus cwj pwm los ntawm electrocautery, hluav taws xob kub hnyiab, carbonization ntawm daim tawv nqaij, thiab mob hnyav, pob txha thiab cov kab mob hauv nruab nrog cev.
Lub electrophysiological physiology ntawm cov kws tshawb fawb tau pom tias tib neeg perceptual tam sim no yog 1.1 mA rau cov txiv neej laus thiab 0.7 mA rau cov poj niam laus; Tam sim no rau cov neeg laus yog 16 mA thiab qhov nruab nrab rau cov poj niam laus yog 10.5 mA. Thaum cov hluav taws xob poob siab tshaj qhov tam sim no, qhov hluav taws xob poob siab tsis tuaj yeem ua kom tshem tawm cov khoom siv hluav taws xob. Yog tias tsis muaj kev quab yuam sab nraud, lub sijhawm hluav taws xob yuav raug ncua ntev thiab kev pheej hmoo ntawm kev tuag yuav tshwm sim. Ob txhais tes thiab ko taw yog qhov yooj yim tshaj plaws ntawm lub cev los ntawm lub cev.
Classification ntawm hluav taws xob kev ua tau zoo tiv thaiv khau
Cov khau tiv thaiv zoo li qub thiab cov khau hluav taws xob tuaj yeem muab faib ua cov khau tawv thiab cov ntaub roj hmab ib leeg khau raws li cov ntaub ntawv. Cov khau tawv tuaj yeem muab faib ua hom nplaum, hom txhaj tshuaj thiab molding hom raws li cov txheej txheem ntau lawm. Cov khau hluav taws xob insulated tuaj yeem muab faib ua cov khau tawv tawv, khau khau khau, khau roj hmab khau thiab khau yas raws li cov khoom siv. Cov khau tawv tuaj yeem muab faib ua hom nplaum, hom molding, txhaj hom thiab seam hom raws li cov txheej txheem ntau lawm. Cov khau tiv thaiv zoo li qub yog cov khau tiv thaiv uas tuaj yeem tshem tawm cov hluav taws xob zoo li qub hauv tib neeg lub cev thiab tiv thaiv hluav taws xob los ntawm hluav taws xob qis dua 250V. Cov khau khiab muaj cov khoom siv hluav taws xob zoo thiab tuaj yeem tshem tawm cov hluav taws xob zoo li qub hauv tib neeg lub cev hauv lub sijhawm luv luv, thiab tsuas yog siv tau rau cov khau tiv thaiv yam tsis muaj kev phom sij ntawm hluav taws xob. Hluav taws xob cov khau yog cov khau tiv thaiv uas tuaj yeem thaiv cov neeg ko taw ntawm cov khoom nyob thiab tiv thaiv hluav taws xob poob siab.
Cov kev cai rau kev tiv thaiv khau
Cov khau tiv thaiv zoo li qub thiab cov khau ua haujlwm raws li GB4385-1995 "cov khau tiv thaiv zoo li qub, cov khau ua haujlwm kev cai", qhov kev tiv thaiv tus nqi yog 100k ~ 1000M thiab tsis ntau tshaj 100k. Ntawm lawv, khau tawv yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm GB1002-1005; daim ntaub roj hmab yuav tsum ua raws li HG / T2495 cov cai. Lub ntsiab kev ua tau zoo ntawm cov khau tiv thaiv zoo li qub thiab cov khau khau, ntxiv rau kev ua haujlwm hluav taws xob, kuj tseem muaj qhov hnav ris tsho, kev sib khi ntawm cov sawb thiab sab sauv, folding ntawm outsole, hnav ntawm outsole, lub zog tev. ntawm nkawm khau thiab lwm yam.
Cov khau hluav taws xob rwb thaiv tsev yuav tsum ua raws li cov kev cai ntawm GB {{0}}} "Cov Txheej Txheem Txheej Txheem rau Hluav Taws Xob Hluav Taws Xob". Cov khoom siv hluav taws xob ntawm cov khau hluav taws xob hluav taws xob thiab cov khau hluav taws xob insulating yog raws li hauv qab no: Thaum cov hluav taws xob xau yog 0.3 mA / kV, cov cai ntawm Table 1 yuav tsum tau ua.
Cov khoom siv hluav taws xob ntawm cov hluav taws xob insulating roj hmab khau looj plab hlaub thiab cov khau hluav taws xob insulating polymeric yog: thaum cov xau tam sim no yog 0.4 mA / kV, yuav tsum tau ua raws li cov lus 2.
Ntxiv nrog rau cov khoom siv hluav taws xob, qhov kev ua haujlwm tseem ceeb ntawm cov khau hluav taws xob hluav taws xob yog lub zog adhesion ntawm lub sab sauv thiab cov sawb, lub zog tensile ntawm lub sab sauv, lub zog adhesion ntawm lub sab sauv thiab cov ntaub, folding kuj ntawm lub outsole, hnav ntawm outsole, tev lub zog ntawm nkawm khau, thiab dej seepage. Kev sib deev thiab lwm yam.
Kev xaiv cov khoom siv hluav taws xob tiv thaiv khau
Kev teeb tsa hluav taws xob tiv thaiv khau yuav tsum ua raws li National Standard GB11651-1989 "Cov Cai rau Kev Xaiv Cov Khoom Tiv Thaiv Kev Ua Haujlwm" thiab "Cov Qauv rau Kev Pabcuam Cov Khoom Siv Tiv Thaiv Kev Ua Haujlwm (Kev sim)" tawm los ntawm Lub Xeev Economic thiab Trade Commission nyob rau lub Peb Hlis 6, 2000 los yog cov kev cai ntawm lub zos thiab kev lag luam. Kev tua tuaj yeem raug xaiv raws li hom kev tiv thaiv kev raug mob thiab chaw ua haujlwm. Piv txwv li, qhov kev pheej hmoo ntawm qhov chaw ua haujlwm feem ntau yog electrostatic kev puas tsuaj, thiab hauv av ua haujlwm yog cov av conductive, koj tuaj yeem xav txog kev siv cov khau conductive; thiab tej zaum yuav muaj hluav taws xob tsawg (250V lossis tsawg dua) hluav taws xob poob rau cov chaw ua haujlwm uas muaj kev phom sij, thiab cov chaw ua haujlwm yog cov av tiv thaiv zoo li qub, cov khau tiv thaiv zoo li qub yuav raug txiav txim siab. Cov khau tiv thaiv zoo li qub thiab cov khau hluav taws xob feem ntau yog siv hauv kev lag luam petrochemical, tshuaj thiab hluav taws xob. Yog tias qhov kev pheej hmoo tseem ceeb hauv qhov chaw ua haujlwm yog hluav taws xob, hluav taws xob rwb thaiv tsev khau yuav tsum tau siv thaum ua haujlwm nyob.
Tsis tas li ntawd, cov neeg siv tuaj yeem xaiv qhov sib txawv ntawm kev ua haujlwm hluav taws xob tiv thaiv khau raws li qhov chaw ua haujlwm. Piv txwv li, nyob rau hauv feem ntau cov khoom siv hluav taws xob thiab kev lag luam tshuaj, ib puag ncig yog huv si thiab kev siv zog ua haujlwm tsawg (tsawg dua). Cov khau tiv thaiv zoo li qub lossis cov khau khau rau ntawm cov roj hmab saum npoo tuaj yeem siv tau, uas yog lub teeb, xis thiab breathable. Kev lag luam petrochemical, suav nrog refueling (gas) chaw nres tsheb, qhov chaw ua haujlwm yog qhov nyuaj dua, kev siv zog ua haujlwm yog qhov siab (ntau taug kev), cov khau tiv thaiv zoo li qub lossis cov khau hluav taws xob tuaj yeem siv tau, uas tuaj yeem tiv taus cov av thiab hnav. Ib yam li ntawd, nyob rau hauv ib qho chaw ua haujlwm nyob nrog lub zog zaus voltage ntawm 1 kV lossis tsawg dua, thiab ib puag ncig yog qhov qhuav, hluav taws xob insulating khau lossis hluav taws xob insulating khau khau nrog lub zog ntawm 15 kV lossis tsawg dua tuaj yeem xaiv. Nyob rau hauv qhov chaw ua hauj lwm uas lub hwj chim zaus voltage siab tshaj 1kV, los yog ib puag ncig yog damp, koj muaj peev xwm siv hluav taws xob rwb thaiv tsev roj hmab khau looj plab hlaub los yog hluav taws xob rwb thaiv tsev yas khau looj plab hlaub nrog ib tug withstand voltage ntawm 15kV los yog siab dua. Hauv kev siv, cov kev cai ntawm Kev Tswj Xyuas Kev Nyab Xeeb Hluav Taws Xob (DL408 thiab DL409) yuav tsum tau ua nruj me ntsis.
