Hluav taws xob zoo li qub nyob rau hauv plastics thiab nws kev tiv thaiv
Cov yas yog txhua cov ntaub ntawv polymer nrog saum npoo thiab ntim resistivity ntau dua 10 ^ 12. Qhov no muab cov plastics zoo heev insulating cov khoom. Txawm li cas los xij, rau tib qho laj thawj, lawv tau raug cuam tshuam rau cov hluav taws xob zoo li qub. Plastics thiab lawv cov khoom nquag nthuav tawm cov indectromagnetic induction thaum ntau lawm, tuav, sib cais, kev sib txhuam, thiab kev sib txhuam, thiab kev sib tsoo. Qhov no tsim cov xwm txheej uas ua rau muaj hluav taws xob hluav taws xob zoo li qub. Yuav ua li cas thiaj tiv thaiv cov hluav taws xob hluav taws xob zoo li qub tau yog ib lub ncauj lus ntawm kev txhawj xeeb thiab kev cia siab tau ntau xyoo.
Lub tswv yim ntawm cov tshuaj tiv thaiv kab mob hauv cov plastics: thaum lawv cov khoom lag luam loj dua 10 ^ 12, lub hluav taws xob zoo li qub; nruab nrab ntawm 8 thiab 10 ^ 12, lawv muaj qee cov tshuaj tua kab mob; nruab nrab ntawm 6 thiab 8 ^ 12, lawv muaj cov tshuaj tiv thaiv zoo; nruab nrab ntawm 4 thiab 6 ^ ^ 12, lawv muaj cov khoom siv antistatic; Thiab hauv qab no 4 ^ 12, lawv pom zoo tshaj plaws, ua raws li cov khoom siv lossis cov ntaub ntawv semiconductor.
Kev tiv thaiv thiab tswj cov hluav taws xob zoo li qub hauv plastics:
1. Ntxiv hygroscopic cov ntaub ntawv uas tsis muaj teeb meem rau plastics (ib tug neeg pab cuam tshuam) txo lawv lub ntsej muag tiv thaiv. Qhov no yog hu ua tus neeg siv tshuaj tua kab mob rau cov plastics. Hom tus neeg sawv cev antistatic siv nyob ntawm seb hom yas. Ob qho tib si ionic thiab tsis {{4} ionic cov tshuaj tiv thaiv ionic ionic yog hygroscopic; Tom qab ntxiv cov tshuaj sib ntxiv no, cov ntaub ntawv nqus dej noo los ntawm huab cua, txo cov npoo tsis kam thiab ua tiav cov tshuaj tiv thaiv kab mob.
2. Piav qhia ncaj qha rau cov khoom siv plastics rau cov txheej txheem txheej txheem yog lub hauv paus chiv keeb ntawm cov plastics (resins). Tam sim no, feem ntau ua kom haum rau hauv kev ua lag luam hauv tsev tseem yog dub ntxiv- los ntawm conductive plastics; Lub teeb - xim conductive strastics tseem tab tom txhim kho.
Xaiv cov conductive plastics:
1. Cov tshuaj tiv thaiv kab mob tau catalorized los ntawm hom yas, suav nrog PVC, suav nrog PVC, PE, ABS, thiab lwm yam, nrog tus nqi tshwm sim los ntawm kaum ntawm Yuan / kg. Qhov nyiaj ntxiv yog 1-3%. Tom qab ntxiv, cov npoo tsis yog feem ntau ntawm 10⁸ thiab 10¹⁰, tshwj xeeb tshaj yog nyob rau thaj chaw muaj cov av noo, qhov twg tus nqi yog qis dua. Cov neeg sawv cev txawv teb cov tshuaj tua kab mob tseem ua haujlwm zoo dua li cov neeg tsis muaj zog, ua tiav qhov kev tiv thaiv ntawm 10⁸ txawm tias nyob hauv cov chaw qhuav. Vim hais tias cov tshuab ntawm kev ua ntawm hom antistatic tus neeg sawv cev tsis tuaj yeem ua ntxiv cov tshuaj tiv thaiv kev ua tau zoo, cov tshuaj tiv thaiv Antistatic ntxiv rau kev tsim khoom, raws li cov khoom siv raw yas ntau yog granular. Nws lub ntsiab lus tseem ceeb yog: tus cab kuj + Antistatic tus neeg sawv cev + Lwm cov neeg nqa khoom ntxiv, nrog cov cab kuj yog LLDPE cob lossis lwm yam Resins.
2. Tam sim no Hom ntau xws li PC, tus tsiaj, PP, PP, PP, PE, Abs, lub duav, PVC, thiab feem ntau yog xim dub. Lub teeb - xim tsis muaj tsawg.
3. Lub teeb {{-} yog ua los ntawm kev ntxiv nano {2} {2} tuaj yeem txo cov npoo hluav taws xob. Tam sim no, lawv yog kim thiab tsis tshua siv, tab sis nyob hauv kev sim siab thiab qib theem. Qhov tshwm sim ntawm cov tshuaj antistatic plastics tau ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa thiab tsim cov khoom siv hluav taws xob, tshwj xeeb yog cov khoom siv yas siv rau cov tshuaj antistatic. Kev tsom xam ntawm cov xwm txheej tam sim no qhia tau nce ntxiv thiab ua kom muaj kev txhim kho kev txhim kho zoo heev!
