Sab hauv ntawm lub hnabcov khoom siv plua plav, cov hmoov av nrog rau kev sib txhuam ntawm huab cua, cov hmoov av thiab cov ntaub lim dej yuav tsim hluav taws xob zoo li qub, cov hmoov av dav dav (xws li cov hmoov av saum npoo av, cov hmoov av tshuaj lom neeg, cov hmoov av thee, thiab lwm yam) tom qab qhov kev sib xyaw ua ke mus txog qee qib (uas yog, qhov txwv tawg), xws li cov hluav taws xob tawm hluav taws xob lossis hluav taws xob sab nraud thiab lwm yam, yooj yim ua rau tawg thiab hluav taws. Yog tias cov hmoov av no raug sau nrog cov hnab ntaub, cov khoom siv lim dej yuav tsum muaj lub luag haujlwm tiv thaiv hluav taws xob zoo li qub. Txhawm rau tshem tawm cov khoom sib sau ua ke ntawm cov khoom siv lim dej, ob txoj hauv kev feem ntau siv los tshem tawm cov hluav taws xob zoo li qub ntawm cov khoom siv lim dej:
(1) Muaj ob txoj hauv kev los siv cov neeg sawv cev antistatic los txo qhov tsis kam ntawm cov tshuaj fibers: ① Kev sib txuas ntawm cov neeg sawv cev antistatic sab nraud ntawm qhov chaw ntawm cov tshuaj fibers: kev sib txuas ntawm hygroscopic ions lossis non-ionic surfactants lossis hydrophilic polymers rau ntawm qhov chaw ntawm cov tshuaj fibers, nyiam cov dej molecules hauv huab cua, yog li ntawd qhov chaw ntawm cov tshuaj fibers tsim cov dej nyias heev. Cov dej zaj duab xis tuaj yeem yaj cov pa roj carbon dioxide, yog li qhov tsis kam ntawm qhov chaw raug txo qis heev, yog li ntawd qhov them tsis yooj yim rau kev sib sau ua ke. ② Ua ntej cov tshuaj fiber raug kos, tus neeg sawv cev antistatic sab hauv raug ntxiv rau hauv polymer, thiab cov tshuaj antistatic molecule raug faib sib npaug hauv cov tshuaj fiber ua los tsim lub voj voog luv luv thiab txo qhov tsis kam ntawm cov tshuaj fiber kom ua tiav cov nyhuv antistatic.
(2) Kev siv cov fiber conductive: hauv cov khoom siv tshuaj fiber, ntxiv qee qhov ntawm cov fiber conductive, siv cov nyhuv tso tawm kom tshem tawm cov hluav taws xob zoo li qub, qhov tseeb, lub hauv paus ntsiab lus ntawm corona tso tawm. Thaum cov khoom siv tshuaj fiber muaj hluav taws xob zoo li qub, lub cev them nyiaj tau tsim, thiab lub teb hluav taws xob tau tsim ntawm lub cev them nyiaj thiab cov fiber conductive. Lub teb hluav taws xob no tau sib sau ua ke nyob ib puag ncig cov fiber conductive, yog li tsim lub teb hluav taws xob muaj zog thiab tsim thaj chaw ua haujlwm ionized hauv zos. Thaum muaj micro corona, cov ions zoo thiab tsis zoo tau tsim, cov ions tsis zoo txav mus rau lub cev them nyiaj thiab cov ions zoo xau mus rau hauv av lub cev los ntawm cov fiber conductive, yog li ua tiav lub hom phiaj ntawm hluav taws xob tiv thaiv zoo li qub. Ntxiv rau cov hlau conductive feem ntau siv, polyester, acrylic conductive fiber thiab carbon fiber tuaj yeem tau txais txiaj ntsig zoo. Nyob rau hauv xyoo tas los no, nrog rau kev txhim kho tas mus li ntawm nanotechnology, cov khoom tshwj xeeb conductive thiab electromagnetic, super absorbency thiab dav band cov khoom ntawm nanomaterials yuav raug siv ntxiv rau hauv cov ntaub absorbing conductive. Piv txwv li, cov pa roj carbon nanotubes yog cov hluav taws xob zoo heev, uas yog siv los ua cov khoom siv ua haujlwm kom nws ruaj khov hauv cov tshuaj fiber spinning kua, thiab tuaj yeem ua rau cov khoom zoo conductive lossis antistatic fibers thiab ntaub ntawm ntau yam molar concentrations.
(3) Cov khoom siv lim dej ua los ntawm cov fiber retardant nplaim taws muaj cov yam ntxwv zoo dua ntawm nplaim taws. Polyimide fiber P84 yog cov khoom siv refractory, tus nqi haus luam yeeb tsawg, nrog rau kev tua tus kheej, thaum nws hlawv, tsuav yog qhov chaw hluav taws tawm mus, tam sim ntawd tua tus kheej. Cov khoom siv lim dej ua los ntawm nws muaj kev tiv thaiv hluav taws zoo. JM lim khoom tsim los ntawm Jiangsu Binhai Huaguang plua plav lim ntaub Hoobkas, nws cov pa oxygen index txwv tuaj yeem ncav cuag 28 ~ 30%, kev sib xyaw ntsug mus txog qib thoob ntiaj teb B1, feem ntau tuaj yeem ua tiav lub hom phiaj ntawm kev tua tus kheej ntawm hluav taws, yog ib hom khoom siv lim dej nrog cov nplaim taws zoo. Nano-composite nplaim taws retardant cov ntaub ntawv ua los ntawm nanotechnology nano-sized inorganic nplaim taws retardants nano-sized, nano-scale Sb2O3 ua tus nqa khoom, kev hloov kho qhov chaw tuaj yeem ua rau cov nplaim taws retardants zoo heev, nws cov pa oxygen index yog ntau zaus ntawm cov nplaim taws retardants ib txwm muaj.
