Anti-static lev
Anti-static lev (hauv pem teb lev) yog tsim los ntawm cov khoom siv hluav taws xob, cov ntaub ntawv qub thiab cov khoom hluavtaws hluavtaws. Ua. Cov khoom no feem ntau yog ob txheej txheej txheej, txheej txheej txheej yog ib txheej zoo li qub, thiab txheej hauv qab yog txheej txheem. Lub lev muaj kev siv ntev ntev, muaj cov kua qaub zoo, alkali thiab tshuaj lom neeg ua haujlwm, thiab hnav tau yoojyim thiab ntxuav yooj yim.
Muaj ob yam ntaub ntawv uas muaj cov tshuaj sib txawv sib txawv, los yog ob cov ntaub ntawv nrog tib yam tshuaj sib xyaw tshuaj, tiam sis nyias muaj nyias lub cev, nyias muaj nyias cov nqi hluav taws xob hauv cov txheej txheem sab hauv. Thaum twg ob yam ntaub ntawv nyob rau hauv kev sib cuag thiab txawm lig los plhws, kev them nyiaj rov qab yuav tshwm sim rau ntawm qhov chaw ntawm lub cev ntawm cov antistatic los ua ib qho hluav taws xob ob txheej. Thaum lawv rov sib cais, txhua yam khoom siv yuav muaj qhov zoo (los yog tsis zoo) nqi uas yog ntau tshaj qhov sib piv thiab kev sib txuam. Qhov txheej txheem ntawm kev them tus nqi yog hu ua electrification.
Cov txheej txheem hluav taws xob feem ntau muaj kev sib txuas lus electrification, triboelectric electrification, photovoltaic electrification, thermoelectric emission electrification, emission electrification, dispersed particle electrification, mechanical fracture electrification, thiab corona electrification. Qhov ntau tshaj yog hu xov tooj hluav taws xob thiab kev them nyiaj rau triboelectric. Cov cwj pwm hluav taws xob ntawm qhov sib txawv ntawm lub teeb meem yuav ua tau ze li ntawm kev sib cuag thiab kev sib cais, uas ua rau them hloov ntawm cov chaw ntawm cov ris tsho tiv thaiv kom tsim hluav taws xob. Txawm li cas los xij, thaum muaj kev sib txuam sib luag heev, vim muaj qhov sib txeeb ntawm qhov sib txig ntawm qhov chaw sib ze ntawm cov tshuaj khau ntawm cov kab mob tseem ceeb, cov khau khaus kuj yuav rhaub los yog muag muag, thiab tej zaum yuav muaj kev sib pauv ntawm ob qhov kev sib txhuam . Vim li no, lub cim ntawm cov khoom siv los tiv thaiv cov khoom siv hluav taws xob muaj qee zaum muaj feem xyuam nrog rau qhov sib txeeb ntawm qhov sib npaug ntawm cov khaub ncaws hnav khaub ncaws. Piv txwv, thaum daim ntaub lo lo ntxhuav khib nyiab yog rubbed nrog cov pas tsis ntxig hlau, cov ntaub zoo yog them thaum lub siab tsis qis, thiab tshuam them thaum lub siab siab. . Lwm qhov piv txwv yog thaum ob tug qhwv roj hmab ntawm tib cov khoom siv rau ib leeg-thiab-ib qho kev sib txhuam hauv kev sib tw, thiab tus pas nrig yog qhov zoo. Tom qab rov qab sib sib zogv heev, tus pas nrig yuavtsum tau them tus nqi zoo. Ntxiv nrog rau txoj kev sib cuag ntawm ob qhov khoom, cov phenomena no kuj yuav tsum xav txog lub Seebeck effect (piv txwv li, qhov txawv ntawm qhov txawv ntawm qhov txawv ntawm qhov hluav taws xob electromotive). Kev sib txhuam ua rau cov cua kub cua hauv zos, uas ua rau muaj cov khoom xa tawm los ntawm kev kub siab kom tsawg. Kev sib txhuam ua rau lub cav tawg thiab thermal decomposition ntawm macromolecules los ua cov electrons lossis ions, nrog rau piezoelectric thiab thermoelectric effects. Yog li ntawd, kev sib txhuam sib zog heev yog txoj hauv kev ua hluav taws xob.
Qhov hluav taws xob ntawm lub tshuab hluav taws xob (polymer) yuav tsum tau kawm ua ke nrog cov qauv siv hluav taws xob. Thaum cov hlau txuas nrog thiab sib cais los ntawm cov khaub ncaws antistatic los yog cov polymer, qhov hluav taws xob yuav tshwm sim los ntawm kev hloov hluav taws xob los yog hloov mus rau lwm tus, tiam sis feem ntau ntawm cov khoom xa hluav taws xob tuaj yeem ua ke nrog ib qhov hloov ntawm ion hloov mus ua hluav taws xob.
Qhov hloov ntawm electron nyob ntawm Fermi zog los yog Fermi qib (E) ntawm tus kwv tiv tauj, thiab nws tus nqi yog sib npaug ntawm electrochemical tej zaum ntawm cov electrons nyob rau hauv cov khoom, yog li E yog ib lub thermodynamic kev ua. Cov electrons uas nkag mus rau hauv qhov khoom yuav raug suav tias xaus ntawm E, thiab txoj kev khiav ntawm electrons los ntawm cov khoom yuav raug suav tias pib ntawm Er hauv nruab nrab. Thaum hloov lub tshuab hluav taws xob sib npaug, Fermi theem ntawm tag nrho lub tsev yuav tsum yog sib npaug hauv daim duab sab nraud. Qhov sib txawv ntawm E. Thaum ob yam khoom sib txuas, cov kev taw qhia ntawm cov hluav taws xob ndlwg nyob ntawm theem Fermi lossis tus nqi ua haujlwm ua ntej sib cuag, thiab cov khoom siv hluav taws xob electron ib txwm ntws los ntawm ib sab (E, qis) uas qhov kev ua haujlwm tseem tsawg (E, siab). Vim tias cov khoom siv hluav taws xob, qhov kev siv hluav taws xob tau tsim tawm. Thaum qhov sib txawv ntawm qhov ua haujlwm ntawm e thiab ob qho khoom sib npaug, qhov sib npaug yog raug pom. Lub sij hawm no, txhua yam khoom muaj qhov sib npaug los sis tsis zoo sib npaug ntawm tus neeg nruab nrab, tab sis yog ntsuas los ntawm sab nraud. Tsis them. Raws li ob qho khoom sib cais, lawv pib tsim cov txiaj ntsig zoo thiab tsis pom zoo, raws li. Hauv kev sib cais, qhov kev soj ntsuam tom qab sib cais yog tshwm sim los ntawm tunneling, field emission, gas discharge, thiab nqi diffusion hauv qhov chaw thiab sab hauv ntawm lub khoom. Tag nrho cov nqi ntawm lub cev muaj peev xwm tsawg dua li tus nqi tag nrho ntawm lub sijhawm sib cuag. Thaum lub sijhawm sib cais lawm, qhov sib txawv ntawm qhov ob yam khoom yog nce sai dua vim yog qhov txo lub zog loj, qhov no ua rau muaj hluav taws xob zoo li hluav taws xob. Qhov tshwm sim ntawm kev siv hluav taws xob yog ib txwm tsis zoo nrog kev ua hauj lwm loj thiab muaj hwj chim zoo nrog txoj haujlwm me me. Cov triboelectric tsuam tawm ntawm qhov polymer yog zoo tib yam rau qhov kev txiav txim ntawm nws txoj haujlwm ua haujlwm loj.
Cov neeg tau sim siv cov khoom siv los tiv thaiv kev mob nkeeg los piav txog lub luag haujlwm ntawm cov neeg tawg rog hauv lub electrostatic them nyiaj rau cov khau los tiv thaiv zoo li qub. Yog hais tias tus antistatic lev muaj ib qhov siab tshaj polarity theem tshaj lub ntsiab saw theem. Tom qab ntawd lub electrification ntawm xws li ib qho kev tiv thaiv antistatic yuav tsum nyob ntawm cov qauv ntawm lub polar pawg. Nyob rau hauv xyoo tsis ntev los no, zoo tshaj plaws tau ua nyob rau hauv daim ntawv thov ntawm quantum kev tshawb xav rau khau antistatic, xws li Andre thiab Del} lall. Tus init initio xam txoj kev thiab ib co qauv ntawm cov qauv siv tau siv los xam lub zog cov qauv siv zog thiab qhov ceev ntawm cov xeev ntawm cov kabmob yooj yim. Siv cov duab xoo hluav taws xob xoos duab xauv duab thiab cov qauv siv los txiav txim siab rau hauv cov qauv hluav taws xob thiab siv los ntsuas cov theoretical results ntawm band. Collins siv Gree. '. Cov kev ua haujlwm zoo tshawb fawb txog qhov teeb meem zoo siab hauv lub xeev hauv cov khib nyiab thiab cov polymers. Brandow tsim cov lus qhia txog kev siv hluav taws xob rau lub kaw ntom nti thiab kab-qhib plhaub, thiab muab cov tshuab 7r electronics Hamiltonian cov neeg ua haujlwm, thiab lwm yam., Uas yog qhov tseem ceeb hauv txoj kev xav ntawm polymer hluav taws xob qauv. Txawm li cas los xij, nyob rau hauv kev sib raug zoo ntawm lub qauv hluav taws xob ntawm lub polymer thiab lub electrostatic them nyiaj, tseem muaj ntau yam theoretical thiab experimental teeb meem uas tsis tau daws, thiab yuav tsum tshawb nrhiav ntxiv yav tom ntej.
