Lub Caij Nyoog Tshiab Ntawm Kev Tiv Thaiv Kev Lag Luam, Yuav Ua Li Cas Tsim Lub Neej Yav Tom Ntej Ntawm Cov Xim Tiv Thaiv Kev Lag Luam Uas Muaj Teeb Thiab Hnyav?

Cov xwm txheej thiab cov yam ntxwv siv tau

• Thaum ntsib nrog qhov chaw muaj kuab paug hnyav heev, cov xim pleev xim tiv thaiv xeb hnyav tau dhau los ua qhov kev xaiv thawj zaug. Xws li kev tsim kho dej hiav txwv, petrochemical, choj loj, chaw nres nkoj, chaw tsim hluav taws xob thiab lwm yam. Cov chaw no feem ntau ntsib ntau yam kev xeb hnyav xws li cov kua qaub muaj zog, alkali muaj zog, tshuaj tsuag ntsev, kub siab, av noo siab, thiab lwm yam, thiab kev ua tau zoo ntawm cov txheej txheem tiv thaiv xeb yog siab heev.
• Cov xim pleev rau kev lag luam uas tiv taus xeb hnyav muaj kev tiv taus xeb zoo heev. Nws tuaj yeem tiv taus cov kua qaub muaj zog, cov alkali muaj zog, cov tshuaj tsuag ntsev, kub siab, av noo siab thiab lwm yam kev xeb hnyav. Nws cov qauv tshwj xeeb thiab cov thev naus laus zis siab heev ua rau cov txheej txheem no ntom thiab ruaj khov, uas tuaj yeem muab kev tiv thaiv mus sij hawm ntev thiab txhim khu kev qha rau cov chaw ua haujlwm.
• Cov xim pleev xim rau kev lag luam uas tiv taus xeb kuj muaj kev tiv thaiv huab cua zoo thiab tiv taus kev hnav. Thaum siv sab nraum zoov ntev, nws tuaj yeem tiv taus qhov kev sim ntawm cov yam ntuj tsim xws li cua thiab hnub, nag thiab daus, thiab nws tsis yooj yim ploj thiab tawg. Tib lub sijhawm, nws kuj muaj qhov nyuaj thiab lub zog siab, thiab tuaj yeem tiv taus kev hnav thiab kev cuam tshuam.
• Tsis tas li ntawd xwb, cov xim ntawm cov xim pleev xim tiv thaiv xeb hauv kev lag luam feem ntau yooj yim, feem ntau yog xim grey thiab dub. Qhov no yog vim tias nyob rau hauv ib puag ncig corrosive hnyav, qhov zoo nkauj ntawm cov xim tsis yog qhov tseem ceeb, tab sis ntau dua kev saib xyuas them rau qhov kev tiv thaiv corrosion thiab lub zog ntawm cov xim.

Cov khoom tseem ceeb thiab cov ntsiab cai kev siv tshuab

• Cov khoom tseem ceeb ntawm cov xim pleev xim hnyav tiv thaiv xeb muaj xws li cov resin ua haujlwm siab, cov xim tiv thaiv xeb, cov khoom sau, cov kuab tshuaj thiab cov khoom ntxiv. Ntawm lawv, cov resin ua haujlwm siab yog cov khoom tseem ceeb ntawm cov xim pleev xim hnyav tiv thaiv xeb, uas txiav txim siab qhov kev tiv thaiv xeb thiab kev ruaj khov ntawm cov xim. Cov resin ua haujlwm siab feem ntau yog epoxy resin, polyurethane resin, fluorocarbon resin thiab lwm yam.
• Cov xim tiv thaiv xeb yog ib feem tseem ceeb ntawm cov xim pleev xim hnyav uas tiv thaiv xeb, uas tuaj yeem ua lub luag haujlwm tiv thaiv xeb. Cov xim tiv thaiv xeb feem ntau yog zinc hmoov, txhuas hmoov, zinc phosphate thiab lwm yam. Cov xim no tuaj yeem tsim cov zaj duab xis tiv thaiv ntom ntom rau ntawm qhov chaw ntawm cov khoom coated, tiv thaiv kev nkag mus ntawm cov yam ntxwv corrosive.
• Lub luag haujlwm ntawm cov khoom sau yog ua kom cov txheej txheej ntau ntxiv, txo tus nqi, tab sis kuj txhim kho qhov tawv ntawm cov txheej, kev tiv thaiv kev hnav thiab lwm yam khoom. Lub luag haujlwm ntawm cov kuab tshuaj yog yaj cov resin thiab lwm yam khoom kom cov xim ua kua sib xws. Cov khoom ntxiv yog cov tshuaj me me ntxiv rau kom txhim kho kev ua haujlwm ntawm cov txheej, xws li cov neeg sawv cev leveling, cov neeg sawv cev defoaming, cov neeg tawg paj, thiab lwm yam.
• Lub hauv paus ntsiab lus ntawm cov xim pleev xim hnyav tiv thaiv xeb yog feem ntau los muab kev tiv thaiv rau cov khoom siv coated los ntawm kev ua haujlwm sib koom ua ke ntawm ntau yam txheej txheem tiv thaiv xeb. Ua ntej, cov txheej txheem txuas ntxiv uas tsim los ntawm cov resin ua tau zoo tuaj yeem ua haujlwm ua lub cev thaiv kom tiv thaiv kev nkag mus ntawm cov yam ntxwv corrosive. Qhov thib ob, cov xim tiv thaiv xeb tuaj yeem tshuaj lom neeg ua rau ntawm qhov chaw ntawm cov khoom siv coated los tsim cov tshuaj ruaj khov uas tiv thaiv kev xeb. Tsis tas li ntawd, cov xim pleev xim hnyav tiv thaiv xeb kuj tseem tuaj yeem txhim kho cov khoom tiv thaiv corrosion ntawm cov txheej txheem los ntawm cov txheej txheem ntawm kev tiv thaiv cathodic thiab kev tiv thaiv corrosion.

Cov txheej txheem tsim kho thiab kev ceev faj

• Cov txheej txheem tsim cov xim pleev xim tiv thaiv xeb hnyav yog qhov nyuaj heev, xav tau pab pawg tsim kho thiab cov txheej txheem tsim kho nruj. Ua ntej tsim kho, feem ntau yuav tsum tau kho qhov chaw ntawm cov khoom siv coated kom ntseeg tau tias qhov chaw huv, qhuav, thiab tsis muaj cov khoom tsis huv xws li roj. Cov txheej txheem kho qhov chaw suav nrog sandblasting, tua blasting, pickling, thiab lwm yam. Cov txheej txheem no tuaj yeem tshem tawm cov khoom tsis huv xws li xeb thiab oxide ntawm qhov chaw ntawm cov khoom siv coated, thiab txhim kho qhov kev nplaum thiab tiv thaiv xeb ntawm cov txheej txheem.
• Thaum lub sijhawm tsim kho, cov yam ntxwv xws li tuab thiab kev sib xws ntawm cov txheej yuav tsum tau tswj hwm. Cov xim pleev xim tiv thaiv xeb hnyav feem ntau yuav tsum tau siv ntau txheej, thiab qhov tuab ntawm txhua txheej muaj cov kev cai nruj heev. Kev tsim kho yuav tsum tau siv cov khoom siv txau lossis cov cuab yeej txhuam kom ntseeg tau tias cov xim tuaj yeem faib sib npaug ntawm qhov chaw ntawm cov khoom siv coated.
• Thaum lub sijhawm tsim kho, nws tseem ceeb heev uas yuav tsum tau them sai sai rau qhov cuam tshuam ntawm qhov kub thiab txias ib puag ncig. Feem ntau, qhov kub thiab txias ntawm cov xim pleev xim tiv thaiv xeb yuav tsum siab dua 5 ° C, thiab qhov av noo yuav tsum qis dua 85%. Yog tias qhov kub thiab txias ib puag ncig qis dhau lossis qhov av noo siab dhau, nws yuav cuam tshuam rau qhov ceev ziab thiab kev ua haujlwm ntawm cov xim. Tsis tas li ntawd, thaum lub sijhawm tsim kho, nws tseem ceeb heev uas yuav tsum tau them sai sai rau qhov cua zoo kom tsis txhob muaj cov kuab tshuaj hauv cov xim.
