Kev paub txog electrostatic thiab kev tiv thaiv electrostatic
1. Lub cim hluav taws xob zoo li qub
Ob cov khoom siv sib txawv nrog cov hluav taws xob sib txawv, los ntawm kev sib txhuam, kev sib tsoo, txau, thiab lwm yam, ntxiv cov nqi zoo rau ib qho khoom tom qab kev sib cuag thiab sib cais, thiab lwm yam khoom tsim kom muaj cov nqi tsis zoo sib luag los tsim hluav taws xob zoo li qub.
Xaj hluav taws xob electrostatic induction, cov nyhuv piezoelectric, hluav taws xob hluav taws xob induction, thiab lwm yam kuj tseem tuaj yeem tsim hluav taws xob muaj hluav taws xob ntau heev. Nrog rau kev tsim khoom thiab kev tsim kho, kev siv cov khoom siv hluavtaws tshiab thiab cov khoom siv insulating tau ua ntau dua thiab ntau dua. Ntxiv rau ntawm cov ntaub ntawv polymer cov ntaub ntawv xav tau rau kev tsim khoom, kuj tseem muaj cov yas thiab pleev xim rau cov chaw ua haujlwm, cov yas pua plag tsev lossis chaw ua luam tawv ntoo, rooj ntoo, yas, thiab cov rooj zaum fiber ntau, tshuaj fiber ntau, nylon thom khwm, khau yas, yas thiab roj hmab hloov khoom lag luam. cov thawv los yog cov ntawv ntim khoom, ntau cov ntawv yas, cov khoom siv hauv chaw ua haujlwm, thiab lwm yam Hauv kev ua kom muaj kev sib txhuam thiab sib cais, lawv yuav ua pov thawj tsis tu ncua, thiab lawv nyuaj rau xa khoom. Lawv tuaj yeem ncav lub zog hluav taws xob thaum lawv sib sau. Thaum cov tshuaj tua hluav taws pom ua rau muaj txim taws, nws yuav dhau los ua tus ua txhaum hauv kev sib tsoo.
Raws li kev faib tawm electrostatic, cov khoom siv dav dav tuaj yeem faib ua peb pawg:
Electrostatic tus neeg xyuas pib, resistivity 10 ^ 6 Ω-cm
Kev Siv Hluav Taws Xob Hluav Taws Xob, qhov siab tawv 10 ^ 6Ω-cm ~ 10 ^ 10Ω-cm
Kev Siv Hluav Taws Xob Hluav Taws Xob, resistivity 10 ^ 10Ω-cm
Ntawm lawv, qhov kev tawm tsam yog 10 ^ 5Ω-cm ~ 10 ^ 9Ω-cm yog hu ua electrostatic tawm hauv lub cev. Lub resistivity ntawm cov khoom siv hluavtaws tshaj yog ntau dua 10 ^ 10Ω-cm, yog li lawv yog cov neeg siv hluav taws xob tsis zoo Rau cov kab hluav taws xob, thaum hluav taws xob zoo li qub tsim tawm, yuav luag tsis muaj txoj kev tawm mus los ntawm nws tus kheej, uas ua rau kev siv hluav taws xob zoo li qub mus thiab nyob ntev ntev. Tom qab kev them nqi tsub zuj zus rau qee yam, kev xa tawm mus rau lwm qhov tuaj yeem tsim kev puas tsuaj.
2. Lub zog zoo li qub
Nyob hauv thaj chaw ua haujlwm, cov khoom tseem ceeb yog:
Cov neeg (txawb hluav taws xob zoo li qub hluav taws xob), qhov hluav taws xob zoo li qub tsim los ntawm tib neeg thaum kev ua ub no txawv ntawm ob peb txhiab volts mus txog kaum tawm txhiab tus volts.
Nyob hauv thaj chaw ua haujlwm, cov khoom tseem ceeb yog:
Cov plag tsev, thaj chaw ua haujlwm, khau, khaub ncaws, hnab ntim khoom zoo nkauj, ntawv ntim hnab, ntawv ntim ua npuas, ntim ntim ncaj qha thiab tshem tawm cov ntawv luam tawm hauv Circuit Court tsis muaj kev tiv thaiv zoo li qub, ungrounded hluav taws xob tsis muaj muag, cov khoom siv tin ua haujlwm, cov cuab yeej ua haujlwm ua los ntawm cov khoom siv insulating, thiab lwm yam Cov. Cov tshuab luam ntawv, ntawv theej duab, hloov pauv, tshuab hluav taws xob, thiab lwm yam kuj tseem tuaj yeem tsim hluav taws xob zoo nkauj thaum lawv ua haujlwm.
Peb, kev phom sij ntawm hluav taws xob zoo li qub
Nrog kev tawm tsam ntawm kev sib koom ua ke loj thiab ntau cov kab sib xyaw thiab lawv cov ntawv thov, cov neeg tau maj mam pom tias tsis paub txog kev puas tsuaj lossis tsis ua haujlwm thaum ntxov ntawm cov cuab yeej yog tshwm sim los ntawm ElectroStatic Kev Tsis Tuaj (ESD). Xws li tshuab hluav taws xob teb lossis hluav taws xob hluav taws xob tsis zoo yuav ua rau muaj kev phom sij lossis kev puas tsuaj rau cov cuab yeej.
Qhov hluav taws xob ntawm electrostatic tawm uas tib neeg lub cev xav tias feem ntau yog siab dua 3000 volts thiab qis dua 3000 volts. Tsis muaj qhov tsis xis nyob, tab sis nws tseem muaj teeb meem rau cov khoom siv hluav taws xob. Tom qab hluav taws xob zoo li qub tsim, ib qho chaw tsim hluav taws xob tsim ib puag ncig nws yuav tsim cov neeg kho tshuab. Muaj ob peb yam cuam tshuam, xws li cov nyhuv tawm hauv paug thiab cov hluav taws xob muaj cov electrostatic. Cov hluav taws xob zoo li qub nqa los ntawm tib neeg lub cev kuj yuav ua rau lwm cov khoom.
Ntawm cov teebmeem no, cov nyhuv tawm ntawm hluav taws xob zoo li qub ua rau muaj kev puas tsuaj ntau tshaj plaws. Txoj kev tshem tawm no ua rau muaj kev puas tsuaj ntawm cov Cheebtsam lossis kev puas tsuaj rau hauv lub system. Kev ua haujlwm ib txwm yog feem ntau hu ua kev puas tsuaj ESD.
Qhov tshwm sim ntawm ESD kev puas tsuaj rau cov Cheebtsam ua rau nyuaj lossis muag muag ”
