There are three basic physical properties of static electricity: 1. Attraction or repulsion 2. There is a potential difference with the earth 3. A discharge current is generated.
Peb cov khoom no tuaj yeem muaj plaub qhov cuam tshuam rau cov khoom siv hluav taws xob:
1. Electrostatic adsorption ntawm plua plav, txo cov rwb thaiv tsev tsis kam ntawm cov khoom (lub neej luv luv).
2. Electrostatic tawm kev puas tsuaj, yog li ntawd cov khoom puas thiab tsis tuaj yeem ua haujlwm (ua kom puas tsuaj tag nrho).
3. Cov cua sov uas tsim los ntawm cov hluav taws xob hluav taws xob hluav taws xob hluav taws xob los yog tam sim no tuaj yeem ua rau cov khoom puas (tuaj yeem puas).
4. Cov hluav taws xob hluav taws xob tsim los ntawm cov hluav taws xob hluav taws xob hluav taws xob muaj qhov loj (txog li ob peb puas volts / meter) thiab qhov dav dav (los ntawm kaum tawm megabytes mus rau ob peb gigabytes), ua rau muaj kev cuam tshuam lossis kev puas tsuaj rau cov khoom siv hluav taws xob (electromagnetic cuam tshuam).
1. Kev zais cia
The human body cannot directly sense static electricity unless an electrostatic discharge occurs. However, the human body may not feel electric shock when electrostatic discharge occurs. This is because the electrostatic discharge voltage perceived by the human body is 2-3KV, so static electricity is concealed.
2. Muaj peev xwm
3. Randomness
Raws li qhov xwm txheej dab tsi yuav cov khoom siv hluav taws xob puas los ntawm hluav taws xob zoo li qub? Nws tuaj yeem hais tias tom qab ib qho khoom tsim tawm, kom txog rau thaum nws raug puas tsuaj, tag nrho cov txheej txheem raug hem los ntawm hluav taws xob zoo li qub, thiab lub cim ntawm cov hluav taws xob zoo li qub kuj yog random, thiab nws qhov kev puas tsuaj kuj yog randomness.
4. Kev nyuaj siab
Kev ntsuas tsis ua haujlwm ntawm cov hluav taws xob hluav taws xob puas tsuaj yog siv sij hawm, siv zog, thiab kim vim qhov zoo, muag heev, thiab cov qauv me me ntawm cov khoom siv hluav taws xob. Nws xav tau cov cuab yeej siv siab, thiab feem ntau yuav tsum tau siv cov cuab yeej ua haujlwm siab xws li tshuab ntsuas hluav taws xob. Txawm li cas los xij, qee qhov kev puas tsuaj ntawm electrostatic yog qhov nyuaj rau kev paub qhov txawv ntawm kev puas tsuaj los ntawm lwm yam laj thawj, uas ua rau tib neeg ua yuam kev los ntawm kev ua tsis tiav ntawm electrostatic kev puas tsuaj raws li lwm yam ua tsis tiav. Qhov no feem ntau yog vim qhov ua tsis tiav thaum ntxov lossis tsis tau piav qhia ua ntej ESD kev puas tsuaj tau nkag siab tag nrho, yog li tsis nco qab npog qhov tseeb ntawm qhov ua tsis tiav. Yog li ntawd, kev soj ntsuam ntawm electrostatic puas rau cov khoom siv hluav taws xob yog qhov nyuaj.
