Cov Cib Uas Tiv Thaiv Acid: Cov Kev Siv Tau Ntau Yam & Cov Kev Daws Teeb Meem Rau Kev Tiv Thaiv Kev Lag Luam

Hauv cov chaw ua haujlwm uas muaj cov kua qaub corrosive, qhov kub thiab txias heev, thiab kev ntxhov siab ntawm cov khoom siv kho tshuab, kev xaiv cov khoom siv tiv thaiv zoo yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb hauv kev ua haujlwm, ua kom lub neej ntawm cov khoom siv ntev dua, thiab txo cov nqi kho.Cov cib uas tiv taus kua qaubsawv tawm ua kev tiv thaiv zoo, muab kev tiv thaiv corrosion zoo heev, thermal stability, thiab durability thoob plaws ntau yam kev lag luam. Qhov tseem ceeb tshaj, cov kev daws teeb meem acid resistant cib tsim tshwj xeeb rau cov kev xav tau tshwj xeeb ntawm cov haujlwm, muab kev tiv thaiv meej uas cov khoom txheem tsis tuaj yeem sib piv.

Cov kev siv cov cib uas tiv taus kua qaub ncaug tau siv ntau yam lag luam, ua rau lawv tsis tseem ceeb hauv cov xwm txheej ua haujlwm hnyav. Hauv cov tshuaj lom neeg thiab petrochemical, lawv tau siv dav ua cov ntaub thaiv rau cov hlab ntsha, cov thoob dej khaws kua qaub, cov chaw da dej pickling, thiab cov kav dej, ua tau zoo tiv taus kev puas tsuaj ntawm cov kua qaub muaj zog xws li sulfuric acid, hydrochloric acid, thiab nitric acid. Rau cov chaw tsim hluav taws xob, tshwj xeeb tshaj yog cov uas muaj cov tshuab flue gas desulfurization, cov cib no tiv thaiv cov pej thuam desulfurization thiab cov khoom siv cuam tshuam los ntawm kev xeb kua qaub, ua kom muaj zog ruaj khov. Kev lag luam metallurgical vam khom lawv rau kev sib txuas ntawm cov cub tawg thiab cov khoom siv ua haujlwm kub siab, qhov twg lawv tiv taus ob qho tib si kev tawm tsam tshuaj lom neeg thiab kev poob siab thermal. Tsis tas li ntawd, lawv zoo tagnrho rau cov chaw ua tshuaj thiab cov chaw ua zaub mov, vim tias lawv cov porosity qis thiab qhov chaw yooj yim ntxuav tau raws li cov qauv kev huv huv thaum tiv taus kev xeb los ntawm cov tshuaj ntxiv thiab cov tshuaj reagents.

Txawm hais tias cov cib uas tiv taus kua qaub txheem ua tau raws li qhov xav tau dav dav, cov kev daws teeb meem tshwj xeeb yog qhov tseem ceeb rau kev daws teeb meem nyuaj lossis tshwj xeeb hauv kev lag luam. Cov kev xaiv kho kom haum rau ntau yam tseem ceeb kom ntseeg tau tias kev hloov kho zoo meej rau cov chaw tshwj xeeb. Hais txog qhov ntev, peb muab cov qhov loj me uas tsim tshwj xeeb - los ntawm cov ntaub nyias nyias 15mm rau cov phab ntsa uas muaj xeb me me mus rau 30mm+ cov cib hnyav rau cov plag tsev lag luam uas hnav hnyav - thiab tuaj yeem tsim cov duab tshwj xeeb xws li cov txiav tsis sib xws kom haum rau cov hlab ntsha nkhaus lossis cov pob qij txha nyuaj. Kev hloov kho cov qauv khoom siv tso cai rau peb kho cov ntsiab lus silica thiab ntxiv cov khoom ntxiv tshwj xeeb raws li hom, kev sib xyaw, thiab qhov kub ntawm cov xov xwm corrosive, txhim kho kev tiv taus cov kua qaub tshwj xeeb lossis cov xwm txheej kub heev. Peb kuj muab cov xim thiab cov qauv nto xaiv, ua rau cov cib sib xyaw nrog kev zoo nkauj hauv kev lag luam thaum tswj kev ua haujlwm.

Peb cov txheej txheem kev cai ua haujlwm tshaj lij ua kom ntseeg tau tias muaj kev ua tau zoo thiab kev siv tau yooj yim. Peb pib nrog kev tshuaj xyuas qhov xav tau tob tob, soj ntsuam cov khoom siv xeb, qhov kub thiab txias, cov khoom siv kho tshuab, thiab cov kev xav tau ntawm kev teeb tsa los tsim ib txoj kev npaj txuj ci tshwj xeeb. Tom ntej no, peb tsim cov qauv rau kev kuaj hauv chaw kuaj mob thiab kev sim hauv tsev kom paub tseeb tias ua tau zoo. Kev tsim khoom ntau ua raws li cov qauv tswj hwm zoo nruj, nrog rau kev sim ua kom tsis txhob muaj kua qaub (txog li 99.8%), lub zog compressive, thiab kev nqus dej (≤0.2%) kom ntseeg tau tias muaj kev sib xws. Thaum kawg, peb muab cov lus qhia kev teeb tsa tshaj lij thiab kev txhawb nqa kev txawj ntse kom ua tau zoo tshaj plaws ntawm cov cib ua raws li kev cai.

Cov cib uas tiv taus kua qaub tsis yog tsuas yog cov khoom siv hauv kev tsim kho xwb - lawv yog kev nqis peev mus sij hawm ntev rau kev nyab xeeb thiab kev ua haujlwm zoo hauv kev lag luam. Txawm hais tias rau cov ntawv thov tus qauv lossis cov haujlwm nyuaj, peb cov kev daws teeb meem muab kev tiv thaiv xeb zoo tshaj plaws rau koj cov kev xav tau. Tiv tauj peb hnub no los tham txog seb peb cov cib uas tiv taus kua qaub tuaj yeem tiv thaiv koj cov chaw ua haujlwm thiab ua kom cov nqi ua haujlwm zoo dua.
