1. Kev Tshawb Fawb Txog Qhov Teeb Meem Tseem Ceeb

1.1 Cov Ua Rau Muaj Teeb Meem Feem Ntau

Thaum cov kws tshaj lij nrhiav cov khau tiv thaiv hluav taws xob hauv cov lag luam uas muaj hluav taws xob ntau, lawv feem ntau nrhiav kev daws teeb meem ntau yam. Hluav taws xob zoo li qub hauv cov lag luam uas muaj hluav taws xob ntau tuaj yeem los ntawm kev siv cov khoom siv, kev sib txhuam, thiab lwm yam. Cov khau ib txwm tuaj yeem khaws hluav taws xob zoo li qub, uas tuaj yeem ua rau muaj ntau yam kev phom sij. Piv txwv li, hauv cov lag luam uas muaj cov khoom siv hluav taws xob thiab tawg, kev tso hluav taws xob zoo li qub tuaj yeem ua rau muaj hluav taws lossis tawg. Ntxiv mus, hluav taws xob zoo li qub kuj tseem tuaj yeem ua rau tib neeg lub cev tsis xis nyob, cuam tshuam rau kev ua haujlwm ib txwm ntawm cov khoom siv hluav taws xob, thiab txo qis kev ua haujlwm. Yog li ntawd, qhov xav tau cov khau tiv thaiv hluav taws xob feem ntau yog kom tshem tawm hluav taws xob zoo li qub thiab xyuas kom muaj kev nyab xeeb thiab xis nyob hauv kev ua haujlwm.

1.2 Cov Xwm Txheej Siv Cuam Tshuam

Cov xwm txheej ua haujlwm uas feem ntau yuav muaj hluav taws xob ntau dhau yog qhov dav heev. Hauv cov lag luam petrochemical, xws li cov chaw ua roj thiab cov chaw tsim tshuaj lom neeg, ntau yam roj thiab kua uas yooj yim hlawv thiab tawg muaj nyob. Hluav taws xob zoo li qub uas tsim los ntawm cov neeg ua haujlwm txav mus los tuaj yeem ua rau muaj kev phom sij loj heev. Hauv kev lag luam tsim khoom siv hluav taws xob, cov khoom siv hluav taws xob rhiab heev raug puas tsuaj yooj yim los ntawm hluav taws xob zoo li qub. Cov neeg ua haujlwm hauv kev lag luam khawb thee kuj tseem yuav muaj kev pheej hmoo vim muaj cov hmoov av thee thiab cov roj methane. Txawm tias nyob rau hauv qee qhov kev lag luam textile thiab ua ntawv, kev ua haujlwm tshuab ceev ceev thiab kev sib txhuam fiber tuaj yeem tsim hluav taws xob zoo li qub ntau heev. Hauv cov xwm txheej no, cov khau tiv thaiv hluav taws xob zoo li qub yog cov khoom siv tiv thaiv tus kheej tseem ceeb.

2. Cov Khoom thiab Cov Txheej Txheem Txoj Cai

Cov khau ua haujlwm tiv thaiv hluav taws xob feem ntau yog ua los ntawm cov ntaub ntawv xws li roj hmab, PVC, lossis lwm yam polymers. Qhov tseem ceeb rau cov khoom tiv thaiv hluav taws xob yog nyob rau hauv kev ntxiv cov neeg sawv cev tiv thaiv hluav taws xob thaum lub sijhawm tsim khoom. Cov neeg sawv cev no tuaj yeem tsim lub network conductive ntawm qhov chaw lossis sab hauv cov khoom, ua rau hluav taws xob static kom sai sai. Piv txwv li, hauv cov khau roj hmab, roj hmab muaj qee qib ntawm kev rwb thaiv tsev. Los ntawm kev ntxiv cov pa roj carbon dub conductive lossis lwm yam neeg sawv cev tiv thaiv hluav taws xob, nws tuaj yeem txo qhov kev tiv thaiv ntawm qhov chaw ntawm cov khau, ua tiav cov teebmeem tiv thaiv hluav taws xob. Cov chaw tsim khoom feem ntau siv cov qauv sib xyaw kom ntseeg tau tias cov khau ua tau raws li cov kev xav tau tiv thaiv hluav taws xob thaum tswj hwm lawv cov kev ua tau zoo hauv lwm yam, xws li kev ruaj khov thiab kev ywj pheej.
