Cov khoom ntawm cov ntaub ntawv nyob rau hauv cov chaw muaj kev sib cav
Feem ntau hais lus, cov ntaub ntawv siv nyob rau hauv txhua qhov chaw tsim khoom tuaj yeem raug cais raws li: insulating, antistatic, zoo li qub- dissipative, thiab conductive.
Insulating cov ntaub ntawv muaj ib qho chaw saum npoo deb ntau dua 10 ^ 14 ω / square. Cov ntaub ntawv insulating zoo li khaws nyiaj, ua rau lawv tsis txaus vim tias tsis tuaj yeem ntws los ntawm insulators. Txhawm rau tiv thaiv kev puas tsuaj los ntawm ESD, cov ntaub ntawv insulating yuav tsum tau ceev tseg ntawm cov hluav taws xob thiab thaj chaw sib dhos. Piv txwv ntawm cov ntaub ntawv no yog plastics, suav nrog polyethylene, polyvinyl chloride, ceramics, thiab roj hmab. Kev sib txuas ua ke nrog cov khoom siv nrog cov khoom siv lossis cov kws tshuaj tua kab mob tuaj yeem tiv thaiv cov khoom ntawm ESD.
Cov khoom siv tiv thaiv tawm tsam rau ntau tiam neeg ntawm hluav taws xob zoo li qub. Cov ntaub ntawv no muaj qhov chaw saum npoo deb ntawm 10 ^ 9 txog 10 ^ 14 ω / square. Lawv muaj lub neej luv luv, yog li lawv rov siv dua rau kev sib sau ua ke cov laug cam thiab hluav taws xob muaj tsawg. Lawv cov lus saum ntuj siab tiv thaiv cov khoom hauv av no yuav tsis rov qab them cov nqi ntxiv.
Zoo li qub -} Cov ntaub ntawv dissipumative muaj ib qho chaw saum npoo (^ 5 txog 10 ^ ω / square. Yog tias koj siv cov khoom siv no los tiv thaiv hluav taws xob zoo li qub thiab txuas staticic -}}}}}}}}}}}}}}}}} Tus nqi rau cov khoom siv los pauv rau hauv av. Kev sib txhuam tuaj yeem tsim kev them nqi siab rau cov ntaub ntawv no, tab sis qhov kev coj ua zoo faib cov nqi them tusyees thoob plaws saum npoo. Cov ntaub ntawv no feem ntau yog siv rau cov ntaub ntawv npog hauv pem teb, cov ntsiav tshuaj, thaj chaw sib dhos, lossis cov khaub ncaws ua haujlwm.
Cov ntaub ntawv conductive muaj qhov chaw tawm saum npoo tsawg dua 10 ^ 5 ω / square. Them nyiaj rau ntawm cov khoom ntawm cov ntaub ntawv tuaj yeem tso tawm rau hauv av. Cov kev lag luam hluav taws xob siv cov plastics doped nrog cov ntaub ntawv conductive rau cov khoom siv hluav taws xob thiab cov laug cam.
