Ua raws li kev txhim kho ntawm kev txhim kho kev lag luam, daim ntawv thov anticorrosive spiral steel kav tau dhau los ua ntau dua, tab sis ntau tus neeg paub me ntsis txog nws cov yam ntxwv, thiab tsawg tsawg paub txog nws kev saib xyuas. Yog li yuav ua li cas thiaj tswj tau thiab tswj cov kav hlau anticorrosive kauv hlau?
Coob leej neeg xav tias cov tshuaj tiv thaiv xeb kauv hlau yeeb nkab yeej tsis xeb. Qhov tseeb, kev tiv thaiv xeb kauv hlau yeeb nkab zoo heev hauv kev tiv thaiv corrosion. Qhov laj thawj yog tias txheej txheej ntawm cov yeeb yaj kiab ua kom huv tau tsim rau saum npoo. Hauv qhov xwm txheej, nws muaj nyob hauv cov duab ntawm cov hlau ruaj khov dua. . Hauv lwm lo lus, txawm hais tias kev tiv thaiv xeb kauv hlau yeeb nkab tsis zoo ib yam raws li daim ntawv thov txheej txheem thiab huab cua oxidation qib sib txawv, nws yog txhua yam oxidized los ntawm huab cua. Qhov xwm txheej no feem ntau hu ua yaig.
Txhawm rau ua kom muaj kev tiv thaiv corrosion ntau dua thiab ua kom zoo nkauj, qhov saum npoo ntawm cov yeeb nkab uas tsis tuaj yeem tiv thaiv kab xev yuav tsum khaws kom huv. Yog hais tias cov tshuaj tiv thaiv xeb kauv hlau yeeb nkab tus lej thiab nplaim nplaim raug xaiv kom raug, thiab phiaj xwm tu tau ua tiav raws sijhawm, nws yuav ua rau muaj tus yam ntxwv zoo thiab ua haujlwm ntev dua. Nco ntsoov kom tsis txhob muaj kuab paug ib puag ncig thiab tsim cov khoom seem ntawm qhov chaw ntawm cov yeeb nkab uas muaj cov kab mob anticorrosive. Cov seem no yuav yog cov hlau zoo lossis xeb tshwm sim thaum lub sijhawm tsim kho ntawm txoj haujlwm. Kev tsim khoom lag luam thiab cov qauv huab cua tsim los ntawm xwm txhua yam ua rau muaj cov khoom sib tov zoo ib yam, xws li ntsev seem hauv qab txheej txheem dej hiav txwv.
Yog li ntawd, cov nplaim ntawm cov yeeb nkab uas muaj anticorrosive kauv hlau yuav tsum tau ntxuav thiab tswj kom raws sijhawm kom tswj tau nws cov nplaim thiab ua kom nws lub neej ua haujlwm zoo dua. Thaum ntxuav cov nplaim hlau anticorrosive kauv cov yeeb nkab, nco ntsoov ua tib zoo saib kom tsis txhob ua rau khawb ntawm qhov chaw, thiab tiv thaiv kev siv cov khoom xyaw tshuaj dawb thiab ntxuav cov kua thiab txhuam txhuam hlau. Txog kev sib tsoo cov cuab yeej tshwj xeeb, thiab lwm yam, txhawm rau tshem tawm cov tshuaj ntxuav, siv dej txias los ntxuav qhov chaw tom qab ntxuav tas.
Ntxuav cov teeb meem tshwm sim
① Tsis pub cov kua txhuam nrog cov hais tau tso cai hauv cov tshuaj ntxuav kom tsis txhob sib tsoo cov plaub hau lossis ua rau txheej txheej puas.
Hen Thaum ntxuav, ua raws cov lus qhia ntawm kab plaub hau thiab ntxuav kom huv.
Fter Tom qab ntxuav nrog dej huv, ntxuav nws nrog dej txias kom ntau, thiab thaum kawg so nws nrog daim ntaub ntub.
2. Kev tu cov tshuaj sib xyaw cov cai: Nws raug nquahu kom yuav cov khoom sib xyaw cov hlau tsis huv raws li cov xwm txheej ntxaws, uas muaj nyob hauv Suav lag luam muag (cov khoom yuav tsum raug txiav txim siab: ph: ib nrab alkali; cov khoom xyaw tshwj xeeb: dej cov ntsiab lus: [GG ] gt; 30%).
3. Nws yuav tsum tsis txhob muaj cov tshuaj kua qaub-alkaline, cov kua qaub heev nrog cov tshuaj chlorine thiab cov tshuaj muaj tshuaj chlorine, tom qab ntawd hydrochloric acid, sulfurous acid thiab cov kua qaub nrog cov pa oxidation.
4. Tus neeg saib xyuas tu kom qhib cov kua nplaum rau cov plaub hau anticorrosive muab kauv hlau kav yuav tsum tsis txo cov kuab tshuaj, xws li ethanol, xylene, thiab toluene.
5. Rau cov kav hlau anticorrosive kauv uas nws qhov chaw tau daws lawm, cov dej huv yuav tsum tau ua tib zoo siv. Cov dej huv uas tsis muaj qhov nruab nrab thiab tsis muaj cov kua sib tsoo yuav tsum tau siv.
