Dab tsi yog qhov tsim nyog Antistatic dab teg thiab pob luj taws?
Tsim nyog antistatic dab teg thiab pob luj taws yuav tsum ua tau raws li peb tus qauv tseem ceeb: hluav taws xob kev nyab xeeb (tam sim no txwv), kev sib cuag ntawm lub cev (conductivity), thiab txhua yam muaj zog, kom ntseeg tau tias qhov hluav taws xob tsis tu ncua thiab kev nyab xeeb ntawm tib neeg lub cev.
I. Core Qualification Indicator: Kev Nyab Xeeb Tam Sim No Limiting Resistor: Ib qho 1-megaohm resistor yuav tsum tau txuas nrog hauv cov kab hauv txoj kev hauv av ntawm lub dab teg thiab pob taws. Muaj nuj nqi: Txhawm rau kom ntseeg tau tias thaum muaj kev sib tsoo hluav taws xob, qhov tam sim no dhau los ntawm tib neeg lub cev raug txwv rau qhov muaj kev nyab xeeb, tiv thaiv hluav taws xob poob rau tus neeg ua haujlwm.
Qhov System Ground Resistance Requirements: Dab teg Strap System: Tag nrho cov kev tiv thaiv ntawm tib neeg lub cev, lub dab teg pluaj, thiab qhov taw tes hauv av yuav tsum tau khaws cia ntawm 1 megaohm thiab 10 megaohms. Heel Strap System: Tag nrho cov impedance ntawm tib neeg lub cev, pob luj taws pluaj, thiab antistatic pem teb feem ntau yuav tsum tau nyob rau hauv ib tug haum ntau yam.
II. Cov yam ntxwv ntxaws ntxaws ntawm Lub Cev Lub Cev Muaj Peev Xwm: Nws yuav tsum tau xaim: Tsis txhob siv li ntawd -hu ua "wireless antistatic dab teg" (uas siv lub hauv paus ntsiab lus ntawm cov ntsiab lus tawm; lawv cov txiaj ntsig tiag tiag tsis muaj lub hauv paus ntawm lub cev thiab tsis tuaj yeem ua tau raws li ESD kev tiv thaiv). Daim tawv nqaij - cov txheej txheem kev sib raug zoo: Sab hauv ntawm lub dab teg yuav tsum muaj cov khoom siv hluav taws xob (xws li cov ntawv hlau tsis muaj steel lossis cov roj hmab conductive) thiab yuav tsum haum snugly tiv thaiv daim tawv nqaij ntawm dab teg; nws yuav tsum tsis txhob hnav khaub ncaws. Ceev- tso tawm plugs: Feem ntau yog nruab nrog cov hlua khi los yog txiv tsawb ntsaws, nws tuaj yeem txuas mus rau qhov chaw ua haujlwm qhov chaw hauv av (EPA). Siab elasticity thiab tensile lub zog: Lub kauj (hauv av xaim) yuav tsum muaj lub zog tensile zoo thiab muaj zog, feem ntau xav tau kaum tawm txhiab qhov kev sim khoov yam tsis muaj kev tawg, thiab muaj qhov tawg - tiv taus tsim. III. Cov yam ntxwv ntxaws ntxaws ntawm cov hlua khau khiab pob taws (cov hlua khau pob taws) rau kev siv sib xws: Cov hlua khi pob taws tsuas yog siv tau thaum siv los tiv thaiv- cov ntaub pua tsev zoo li qub (lossis cov ntaub pua tsev). Nws raug pom zoo kom hnav ob txhais taw ib txhij los xyuas kom meej tias tsawg kawg ib ko taw tseem nyob hauv av thaum lub sijhawm txav mus los. Conductive daim kab xev txuas mus rau hauv cov khau: Lub conductive webbing (dub nplaig) yuav tsum tau muab tais rau hauv khau, ua ncaj nraim nrog tus neeg siv cov thom khwm lossis cov tawv nqaij, thaum sab nrauv txuas nrog cov roj hmab conductive ntawm ib sab ntawm cov khau ntawm ib lub buckle. Cov khoom siv tsis yog-kos npe: Siab- cov hlua khau zoo yuav tsum siv cov roj hmab uas tsis muaj qhov cim tseg, tsis txhob muaj cov xim dub ntawm cov plag tsev huv si. IV. Kev tshuaj xyuas txhua hnub thiab kev saib xyuas: Txawm tias cov khoom tsim nyog tshaj plaws yuav ua tsis tiav vim hnav thiab tsim kua muag. Yog li ntawd, cov txheej txheem kev ntsuam xyuas hauv qab no yuav tsum tau ua raws li: Kev Ntsuas Txhua Hnub: Ua ntej txhua qhov kev hloov pauv, yuav tsum siv lub tshuab ntsuas hluav taws xob zoo tshaj plaws (ESD) .
Hloov tsis tu ncua: Lub dab teg pluaj thiab pob luj taws yog cov khoom siv. Rau siab - cov kab ntau lawm, kev hloov tsis tu ncua (xws li, txhua 3 lossis 6 lub hlis) raug pom zoo, lossis yuav tsum tau muab pov tseg tam sim yog tias muaj cov tsos mob ntawm kev laus, ncab deformation, lossis hnav cov txheej txheem tshwm sim. Yog tias koj tab tom yuav khoom los tiv thaiv- cov khoom siv zoo li qub rau cov kab ntau lawm lossis cov chaw kuaj mob, cov kev daws teeb meem yuav tsum tau tsim raws li cov neeg ua haujlwm cov haujlwm ntau yam: Yog tias cov neeg ua haujlwm yuav tsum tau txav mus los tsis tu ncua, pob luj taws (siv nrog rau kev tiv thaiv - khau zoo li qub) yog qhov tsim nyog. Yog tias cov neeg ua haujlwm feem ntau ua haujlwm hauv qhov chaw zaum, lub dab teg yog qhov kev xaiv zoo tshaj plaws thiab txhim khu kev qha hauv av.
