Dab tsi yog qhov kev tiv thaiv nto
Surface resistance kuj tseem hu ua qhov tshwj xeeb tiv thaiv. Cov ntaub ntawv tseem ceeb qhia txog cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob los yog cov khoom siv insulating.
Nws sawv cev rau qhov tsis kam ntawm ib cheeb tsam ntawm lub dielectric nto mus rau qhov dej ntws tawm tam sim no ntawm sab nraud ntawm lub square. Lub unit yog ohms. Qhov loj ntawm qhov chaw tiv thaiv tsis yog tsuas yog txiav txim siab los ntawm cov qauv thiab muaj pes tsawg leeg ntawm dielectric, tab sis kuj muaj feem xyuam rau qhov hluav taws xob, qhov kub thiab txias, qhov chaw ntawm cov khoom, kev ua haujlwm thiab cov av noo. Ambient humidity muaj kev cuam tshuam zoo rau saum npoo tsis kam ntawm dielectrics. Qhov ntau dua qhov kev tiv thaiv saum npoo, qhov zoo ntawm rwb thaiv tsev ua haujlwm.
11 ohms nrog qhov tsis kam ntau dua lossis sib npaug li 10 yog cov insulators.
Ntau dua lossis sib npaug ntawm 10, 4 thiab tsawg dua 10, 11 ohms yog antistatic (static dissipative).
3 tsawg dua 10 yog cov khoom siv hluav taws xob tiv thaiv. —— ANSI/ESD 541-2008 tus qauv
Muaj cov tshuaj tiv thaiv saum npoo ntawm kev ua lag luam los ntsuas qhov muaj peev xwm tiv thaiv zoo li qub ntawm cov khoom siv los tiv thaiv zoo li qub los ntawm kev ntsuas qhov tsis kam ntawm cov khoom tiv thaiv zoo li qub.
