Yuav ua li cas kom paub qhov txawv ntawm cov ntaub ntawv antistatic thiab insulating cov ntaub ntawv
Antistatic cov ntaub ntawv yog cov khoom uas tiv thaiv cov khoom thiab cov khoom ntawm raug puas thiab puas los ntawm cov hluav taws xob zoo li qub. Cov khoom siv hluav taws xob yog cov khoom siv tsis ua haujlwm. Yog li cas koj yuav paub qhov txawv ntawm cov ntaub ntawv los ntawm cov khoom qub los ntawm ib tug kws thiab kev xaav? Cia kuv qhia koj qhov txawv ntawm ob.
Cov khoom siv uas tiv thaiv electrostatic: Qhov dav hlau tawv txaus ntawm qhov khoom yog tsawg tshaj li 1 × 10 ^ 4Ω / m ^ 2 los yog lub ntim qhov tawv nqaij tsis yog ntau tshaj 1 × 10 ^ 3Ω / cm ^ 3. Lub hau tiv thaiv Faraday tiv thaiv ntawm cov ntaub ntawv no tuaj yeem tiv thaiv tau cov khoom siv hluav taws xob los ntawm kev cuam tshuam. Zoo li qub teebmeem. Cov ntaub ntawv thaiv cov ntaub thaiv (electrostatic shielding) yog ib feem ntawm cov khoom siv hlau electrostatic.
Cov khoom siv: Cov av tawv tsis txaus ntawm qhov khoom tsis pub tshaj 1 × 10 ^ 5 Ω / m ^ 2 lossis qhov ntim qhov tsis taus tsis tshaj 1 × 10 ^ 4 Ω / cm ^ 3. Cov khoom siv no muaj hluav taws xob tsis zoo, thiab electrons ntws yooj yim heev ntawm nws qhov chaw thiab sab hauv, cia nws ntws rau lwm tus neeg xyuas pib lossis hauv av uas nyob hauv kev sib cuag.
Qhov dav hlau ntawm qhov av zoo li qub yog qhov ntau tshaj 1 × 10 ^ 5 Ω / m ^ 2 tab sis tsawg dua los yog sib npaug li 1 × 10 ^ 12 Ω / m ^ 2, los yog qhov ntim kom muaj zog tshaj 1 × 10 ^ 4 Ω / cm ^ 3 tab sis tsawg dua 1 × 10 ^ 11 Ω / cm ^ 3.
Cov khoom siv hluav taws xob: Qhov dav hlau ntawm qhov khoom muaj ntau tshaj 1 × 10 ^ 12 Ω / m ^ 2, los yog lub ntim resistivity siab tshaj 1 × 10 ^ 11 Ω / cm ^ 3. Muaj qhov tsis tshua muaj tam sim no ntws los ntawm sab hauv los yog hauv cov khoom siv thev dej, thiab nws qhov kev ua haujlwm loj thiab nws nyuaj rau hauv av. Tus nqi them rau hauv cov ntaub ntawv no yuav nyob twj ywm rau nws ntev.
