Cov ntsiab lus ntawm kev tiv thaiv electrostatic
Txhua qhov teeb meem hauv cov xwm txheej yog tsim ntawm atoms. Protons (raug nplua) thiab electrons (tsis raug tsub) nyob rau hauv atoms muaj nyob rau hauv txhua txhua sab ntawm peb lub neej. Nws tuaj yeem hais tias hluav taws xob muaj nyob txhua qhov chaw, txhua qhov chaw. Nws ib txwm muaj nyob thoob plaws txhua yam hauv peb lub neej. Nws yog ib qho nyuaj rau tshem tawm hluav taws xob hluav taws xob thaum lub sijhawm siv hluav taws xob tiv thaiv, tiam sis peb tuaj yeem siv kev ntsuas tiv thaiv kom txhob muaj peev xwm thiab tsim tawm hluav taws xob. Tom qab xyoo dhau los ntawm kev tshawb fawb thiab kev xyaum los ntawm cov kws tshawb fawb thiab cov neeg tsim khoom, cov txiaj ntsim tau tshwm sim tau hais tias Ob txoj hauv paus ntsiab lus tiv thaiv kev tiv thaiv kev tiv thaiv electrostatic:
1 Siv lossis nruab nruaj nyhav rau ntawm qhov chaw uas muaj xwm txheej zoo li qub.
2 Thauj khoom electrostatic rhiab nrog cov ntim electrostatic shielding
Surfactant hom tshuaj antistatic muaj ntau yam tsis zoo thaum siv, xws li tsis muaj kev ruaj ntseg antistatic nyhuv, deterioration ntawm qhov chaw vim los ntawm cov nag, thermal decomposition thaum ua, thiab siab nyob ntawm kub thiab humidity. Cov teeb meem saum toj no yuav daws tau los ntawm kev siv ntau hom roj polymers ua cov neeg ua hauj lwm antistatic. Qhov sib ntxiv ntawm ntau hom polymers xws li polyethylene oxide (PEO) ua ib qhov chaw ua hauj lwm rau lub matrix rein rau ib qho kev ua txhua yam mus tas li ib qho kev tiv thaiv kab mob. Cov kev sib txuas ntawm hydrophilic uas muaj cov khoom siv hluav taws xob muaj qhov txawv ntawm cov txheej txheem tsis tshua muaj kev sib haum xeeb uas tsis tshua muaj pes tsawg lub cev tshuaj tiv thaiv los ntawm cov kab mob siab loj, thiab hu ua polymeric mus tas li cov tshuaj tiv thaiv.
Cov nyhuv ntawm cov polymeric antistatic agent alloyed nrog yas nyob ntawm seb nws cov degree of dispersion thiab dispersion hauv lub cob. Qhov zoo tshaj plaws tis lub xeev yog tias tus neeg saib xyuas antistatic yog finely faib rau hauv matrix rein, thiab nws cov duab yog nyob rau hauv daim ntawv ntawm ib tug kab los yog ib lub hlwb, sib sau ib txoj kev rau kev nqi nqi. Lub realization ntawm no lub xeev tis yog nyob ntawm cov compatibility thiab kev mob ntawm tus polymeric antistatic tus neeg saib xyuas thiab matrix re. Ib qho kev sib haum xeeb tsim nyog xaiv tau los kho qhov loj me me ntawm tus neeg saib xyuas cov neeg ua hauj lwm dispersion, thiab qhov sib txawv ntawm qhov sib txuam ntawm niam txiv thiab cov dispersed theem yog kev tswj los ntawm kev tswj cov kev sib ncawg thiab kev ntsuas kub. Nyob rau hauv lub microdomain qauv li tswj, lub antistatic tso npe ua ib tug zoo "kev sib txuas". Anti-static hnab
Ntxiv nrog rau ntxiv rau ib pob tshuaj los ua ib qho polymer alloy uas muaj cov tshuaj tua kab mob, tus kab mob polymeric antistatic kuj yog siv rau txheej. Yog tias lub polymer uas muaj quaternary ammonium ion conductive unit yog siv los ua ib txheej tawv yas (daim ntawv, zaj duab xis, thiab lwm yam), nws pom cov khoom zoo antistatic.
