Hluav taws xob cov khoom siv roj hmab
General roj hmab yog ib qho zoo heev hluav taws xob insulator. Cov roj hmab ntuj, butyl roj hmab, ethylene propylene roj hmab thiab styrene butadiene roj hmab tag nrho muaj cov khoom siv hluav taws xob zoo, yog li lawv tau siv dav hauv cov cables insulated. Nitrile butadiene roj hmab thiab chloroprene roj hmab muaj cov khoom tsis zoo dielectric vim muaj cov polar atoms lossis atomic pawg hauv lawv cov molecules. Ntawm qhov tod tes, ntxiv conductive fillers xws li conductive carbon dub los yog hlau hmoov rau hauv roj hmab yuav ua rau nws muaj txaus conductivity rau disperse static nqi, los yog txawm ua ib tug conductor.
