Qhov tseem ceeb tshaj plaws yam ntxwv ntawm antistatic additives yog txo cov resistivity ntawm cov ntaub ntawv thiab tiv thaiv static hluav taws xob tsub zuj zuj. Lawv cov cim tseem ceeb feem ntau suav nrog qhov kev tiv thaiv saum npoo, ntim cov khoom tiv thaiv, thiab lub sijhawm them nyiaj lwj. Cov ntaub ntawv sib txawv muaj qhov sib txawv rau kev ua haujlwm antistatic; Feem ntau, cov ntaub ntawv uas muaj qhov chaw tiv taus ntawm 10^9 thiab 10^12 Ω raug suav hais tias muaj cov khoom zoo li qub. Antistatic cov neeg ua haujlwm qhia cov pab pawg hydrophilic, ionic pawg, lossis cov kab hluav taws xob, tso cai rau cov kab dej ntawm cov dej molecules kom adsorbed los yog tsiv teb tsaws ntawm lossis nyob rau hauv cov khoom nto, yog li tso tawm sai sai thiab txo cov plua plav adsorption, muaj kev pheej hmoo, thiab electrostatic cuam tshuam.
Nyob rau hauv cov nqe lus ntawm physicochemical zog, antistatic additives muaj zoo thermal stability, tshuaj stability, thiab dispersibility. Lawv yuav tsum tswj hwm cov qauv thiab kev ua haujlwm ruaj khov nyob rau hauv siab -kev ua haujlwm kub (xws li kev txhaj tshuaj molding, extrusion, thiab tshuab tshuab) thiab tsis hnov mob rau cov khoom siv hauv paus. Nyob rau tib lub sijhawm, txhawm rau ua kom muaj txiaj ntsig zoo, cov tshuaj tiv thaiv kab mob yuav tsum tau yooj yim thiab tsis sib haum xeeb hauv cov yas, txheej, lossis fibers yam tsis muaj kev cuam tshuam rau cov khoom siv pob tshab, hloov pauv, thiab cov khoom siv kho tshuab. Rau masterbatch los yog kua dispersion khoom, dispersibility ncaj qha txiav txim siab uniformity thiab persistence ntawm antistatic nyhuv.
Antistatic additives muaj qhov ntev - ua haujlwm tau zoo thiab tswj tau kev tsiv teb tsaws chaw. Kev tsiv teb tsaws yog hais txog lub peev xwm ntawm tus neeg sawv cev antistatic los ntawm cov khoom siv sab hauv mus rau nws qhov chaw los tsim cov txheej txheem zoo. Kev tsiv teb tsaws ntau dhau tuaj yeem ua rau kev ua haujlwm ntawm qhov chaw degradation, thaum tsis txaus tsiv teb tsaws tuaj yeem cuam tshuam rau thawj zaug antistatic nyhuv. Yog li ntawd, siab -cov tshuaj tiv thaiv zoo tshaj plaws feem ntau sib npaug ntawm qhov pib sai sai nrog kev ruaj ntseg ntev -, kom ntseeg tau tias cov khoom muaj kev tiv thaiv zoo nyob rau hauv tag nrho nws lub neej kev pab cuam thaum ua tau raws li ib puag ncig thiab kev nyab xeeb.
