Hauv cov xwm txheej xws li cov khoom siv hluav taws xob semiconductors, cov cuab yeej siv precision, petrochemicals, thiab cov chaw ua haujlwm plua plav, kev sib sau ua ke ntawm hluav taws xob static tuaj yeem ua rau muaj ob hom teeb meem: ib qho yog kev tawg ntawm cov khoom rhiab heev los ntawm kev tso tawm electrostatic (ESD), thiab qhov thib ob yog qhov kev pheej hmoo ntawm kev kub hnyiab hauv cov chaw kub hnyiab thiab tawg. Ob qho tib si conductive casters thiab anti-static casters yog siv rau "kev tswj hwm them", tab sis lub hom phiaj thiab cov txheej txheem siv sib txawv. Kev xaiv qhov tsis raug tuaj yeem ua rau tsis ua tiav ntawm kev tswj hwm kev pheej hmoo.
Ua ntej, cia peb muab ib qho xaus lus: yuav ua li cas xaiv qhov yog ib qho ntawm ib qho kev pom?
Thaum nws los txog rau qhov kub hnyiab thiab tawg (cov kuab tshuaj, roj thiab roj av, kev pheej hmoo ntawm hmoov av tawg) lossis kev pheej hmoo ESD huv heev / qib chip, qhov tseem ceeb yuav tsum muab rau "cov khoom siv hluav taws xob" (uas xav tau kev tshem tawm sai).
Feem ntau yog xav kom txo qhov electrostatic suction thiab zam kev cuam tshuam me me (feem ntau yog nyob rau hauv cov chaw tsim khoom siv hluav taws xob thiab kev thauj mus los ntawm cov cuab yeej): xaiv "anti static casters" (kom cov nqi maj mam ploj mus).
Txawm xaiv qhov twg los xij: ib txwm xyuas seb qhov 'grounding link' puas tiav, txwv tsis pub txawm tias qhov zoo tshaj plaws kuj yuav ua tsis tiav.
1. Qhov sib txawv ntawm lub hauv paus: Cov hom phiaj sib txawv → Cov qib tiv thaiv sib txawv → Qhov ceev tso tawm sib txawv
1) Cov Caster Conductive
Lub Hom Phiaj: Tshem tawm cov nqi uas lub cuab yeej / lub cev tib neeg tsim tawm sai sai, zam kev tso tawm tam sim ntawd tom qab sib sau ua ke.
Kev Siv: Los ntawm kev tsim ib txoj kev tiv thaiv qis ntawm cov khoom siv hluav taws xob thiab cov qauv hlau, cov nqi raug coj mus rau hauv av / av system.
Kev tiv thaiv ib txwm muaj: Qhov kev tiv thaiv ntawm lub voj voog feem ntau yog ≤ 10 ⁴ Ω (txawv tus qauv/txheej txheem ntsuas yuav txawv, thov saib daim ntawv qhia kev xeem kom paub tseeb).
Kev tso tawm ceev: ceev (ze rau "kev tso tawm tam sim ntawd").
2) ESD/Dissipative Caster
Lub Hom Phiaj: Txhawm rau kom tsis txhob muaj cov nqi hluav taws xob sib sau ua ke, tswj cov peev xwm electrostatic hauv qhov chaw nyab xeeb, thiab txo cov teeb meem micro discharge thiab cov hmoov av sau.
Kev Siv: Siv cov ntaub ntawv dissipative / txheej txheej kom cov nqi "maj mam tso tawm" es tsis txhob nrhiav kev tiv thaiv qis heev.
Qhov tsis kam ib txwm muaj: feem ntau nyob rau hauv qhov ntau ntawm 10 ⁵ -10 ⁹ Ω (feem ntau nyob rau hauv theem ntawm 10 ⁶ -10 ⁸ Ω, tseem raug rau daim ntawv qhia kev xeem).
Tso tawm ceev: qeeb (hom dissipative).
2. Cov Khoom Siv thiab Cov Qauv: Kev coj hluav taws xob xav tau "txoj kev", kev tiv thaiv hluav taws xob xav tau "kev tiv thaiv tswj tau"
1). Cov txheej txheem dav dav rau cov neeg ua haujlwm conductive:
Lub cev log: Roj hmab conductive/conductive PU/lub log hlau (tsis tshua muaj), feem ntau ua tiav nrog kev tiv thaiv qis los ntawm cov khoom siv conductive xws li carbon dub.
Cov khoom siv txuas thiab cov khoom siv sib txuas: Cov khoom siv hlau feem ntau yuav tsim ib txoj kev loj uas siv hluav taws xob, thiab qee qhov yuav raug tsim los nrog cov khoom sib txuas hauv av kom ntseeg tau tias muaj kev sib cuag nrog cov khoom sib txuas hauv av.
Cov ntsiab lus tseem ceeb: Cov log, cov brackets, cov khoom siv, thiab av yuav tsum tau txuas nrog (kev tiv tauj tsis pub "tawm").
2). Cov txheej txheem dav dav rau cov neeg ua haujlwm tiv thaiv kev ua haujlwm zoo li qub:
Lub cev log: dissipative PU / roj hmab / PP, thiab lwm yam, tswj qhov kev tiv thaiv hauv qhov nruab nrab los ntawm cov neeg sawv cev tiv thaiv static lossis cov khoom sau dissipative.
Qaum: Feem ntau tsis tas yuav tsim cov qauv hluav taws xob ntxiv, tab sis yuav tsum tsis txhob siv cov khoom thaiv rwb thaiv tsev (xws li cov yas, cov yeeb yaj kiab pleev xim tuab, cov tes tsho ncej rwb thaiv tsev, thiab lwm yam) los ua cov khoom thaiv rwb thaiv tsev.
Lub ntsiab lus tseem ceeb: Nws tsis yog tias cov khoom siv hluav taws xob ntau dua, qhov zoo dua, tab sis qhov kev tiv thaiv yuav tsum tau tswj hwm hauv qhov ntau uas tuaj yeem tso tawm yam tsis nrawm dhau.
