Kev ntsuas kev ua tau zoo los tiv thaiv kom xeb ntawm cov hlab ntsha siab

1. Tsim nyog xaiv ntawm cov ntaub ntawv
Xaiv cov ntaub ntawv raws li cov yam ntxwv nruab nrab: Xaiv cov khoom siv corrosion uas haum rau hom, siab, siab thiab lwm yam ntawm cov muaj feem ntawm cov hlwv ntawm lub siab. Piv txwv li, rau cov thawv muaj dilute sulfuric acid, siab-silicon nrum hlau tuaj yeem siv; Rau muaj zog oxidizing cov kua qaub, stainless hlau yog qhov kev xaiv zoo dua.
Txiav txim siab cov khoom siv: Ntxiv rau kev txhim kho corrosion, lub zog, kev ua tau zoo, thiab lwm yam ntawm cov khoom yuav tsum tau txiav txim siab. Piv txwv li, nyob rau hauv cov kev kub siab thiab cov khoom siv siab ua kom muaj lub zog zoo, tab sis lawv kuj yuav tsum tau muaj lub zog zoo thiab siv tau kom muaj kev nyab xeeb ntawm lub thawv.
2. Tswj cov haujlwm ua haujlwm
Tswj cov khoom nruab nrab ntawm nruab nrab: nruj me ntsis tswj qhov kub thiab txias, pawj muaj nuj nqis thiab lwm yam nqi ntawm lub siab nyob rau hauv lub siab ntsha kom tsis txhob overheating thiab tsis meej thiab tsis meej pem nruab nrab muaj pes tsawg leeg. Piv txwv li, hauv qee cov xov xwm alkaline, nws yog qhov tsim nyog los tiv thaiv tus nqi PHU los ntawm kev ua kom dhau los ua rau Alkali embrittlement; Rau roj media muaj dej, nws cov ntsiab lus dej yuav tsum tau tswj kom tiv thaiv kev tsim ntawm corrosive dej zaj duab xis.
Tshem tawm cov teeb meem tsis zoo: tshem tawm lossis tswj cov roj ntsha hauv nruab nrab, thiab lwm yam, tshem tawm cov pa oxygen ua tau zoo rau cov pa roj carbon steel; Rau cov xov xwm muaj chloride thiab lwm txoj kev tuaj yeem siv los tshem tawm chloride breading ntawm stainless hlau.
3. Siv thev naus laus zis thev naus laus zis
Txheej Txheej Txheej: Siv tshuaj tiv thaiv corrosion xws li Epoxy Resin Txheej Txheem thiab sab nraud ntawm cov hlau los ntawm qhov nruab nrab ntawm txoj kev tiv thaiv corrosive thiab ua si lub luag haujlwm tiv thaiv. Ua ntej txheej kev tsim kho, cov npoo ntawm lub thawv yuav tsum tau nruj me ntsis kho mob thiab roj tshem tawm kom ntseeg tau tias txheej thiab substrate.
Cov kev tiv thaiv ob sab: Xaiv cov ntaub ntawv hauv cov khoom hauv cov khoom siv hauv nruab nrab, thiab lwm yam ntawm cov khoom siv roj hmab los ntawm kev hu rau cov khoom siv lub cev. Piv txwv li, hauv cov khoom khaws cia hydrochloric acid, siv roj hmab hauv cov roj hmab tuaj yeem muaj cov nyhuv tiv thaiv zoo.
Corrosion Kev Tiv Thaiv: Ntxiv ib qho nyiaj tsim nyog ntawm corrosion inhibitor mus rau hauv nruab nrab tuaj yeem inhibit hlau corrosion. Muaj ntau hom corrosion inhibitors, uas yuav tsum tau raug xaiv raws li cov xov xwm txawv thiab cov khoom siv. Piv txwv li, hauv nruab nrab cov kua aqueous, anodic corrosion inhibitors xws li sodium nitrite tuaj yeem siv; Hauv cov acidic nruab nrab, organic corrosion inhibitors xws li Urotropine ntau feem ntau siv.
4. Lub zog ntawm kev tswj hwm
Kev kuaj thiab kev saib xyuas tsis tu ncua: tsim cov ncauj lus kom ntxaws thiab kev soj ntsuam cov phab ntsa siab tsis tu ncua, thiab lwm yam kev puas tsuaj rau kev phom sij thiab ua rau kev ntsuas kho kom zoo. Rau qhov chaw corroded me ntsis pom, lawv tuaj yeem kho los ntawm kev sib tsoo, kho vuam thiab lwm txoj kev; Rau cov chaw ua rau muaj kev puas tsuaj loj, qhov chaw puas yuav tsum hloov nyob rau lub sijhawm.
Ua kom haum rau cov txheej txheem ua haujlwm: Cov neeg ua haujlwm yuav tsum ua raws cov txheej txheem kev ua haujlwm kom tsis txhob muaj kev ntxhov siab ntawm kev ua kom mob siab rau kev ua haujlwm ntawm corrosion vim kev ua haujlwm yuam kev. Piv txwv li, hauv cov txheej txheem ntawm kev nce siab ntxiv, txo qhov ntsuas kub thiab qhov ntsuas kub kom tiv thaiv kom tsis txhob muaj qhov kub thiab txias kom tsis txhob muaj kev ntxhov siab corrosion; Nyob rau tib lub sijhawm, nws yog qhov tsim nyog kom tsis txhob lub ntim ntim nyob rau hauv tag nrho cov khoom siv lossis tsis muaj zog thauj khoom ntev thiab tswj kev ua haujlwm ruaj khov.
