Vim muaj kev sib koom ua ke, cov cib fim zoo tshaj plaws los txo qhov kev pheej hmoo ntawm SCC tsis yog nyob rau hauv lub sijhawm ua haujlwm ntawm cov txheej txheem piping, kev kaw lus, lossis lwm yam kev siv stainless hlau.
Qhov zoo tshaj plaws, kev txiav txim siab nyob ib puag ncig SCC yuav tsum pib ntawm theem tsim qauv -- suav nrog kev xaiv cov khoom, kev tswj ib puag ncig, thiab txo kev ntxhov siab thiab tshem tawm.
Thaum qhov ua tau zoo rau SCC yog siab, cov kws ua haujlwm yuav tsum ua tib zoo tsim cov kav dej kom txo tau qhov kev ntxhov siab. Lawv kuj yuav tsum xav txog qhov cuam tshuam ntawm cov kev daws teeb meem corrosive siv.
Pitting Resistance Equivalent Numbers (PRENs) los yog Pitting Resistance Equivalent Values (PRE-values) tuaj yeem ua qhov pib zoo tshaj plaws los ntsuas cov hlau uas muaj kev cuam tshuam rau kev ntxhov siab corrosion. Txawm hais tias ob hom kev xeb tsis zoo ib yam, kev tawm tsam feem ntau pib ua zoo sib xws. Qhov no tso cai rau PRENs los ua qhov taw qhia ntawm SCC tsis kam.
Qhov tseem ceeb tshaj, tag nrho cov concentration theem -- tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem uas muaj chlorides los yog sulfides -- thaum lub sij hawm ua hauj lwm npaj yuav tsum tau soj ntsuam thiab kwv yees kom muaj kev ruaj ntseg.
Raws li tau hais tseg hauv peb phau ntawv qhia txog kev txhim kho corrosion, qhov concentration ntawm ib cheeb tsam tshwj xeeb lossis thaj chaw kaw ntawm cov txheej txheem piping lossis ib puag ncig kev lag luam feem ntau tuaj yeem tshaj qhov concentration ntawm cov kev daws teeb meem uas siv rau hauv cov txheej txheem.
Qhov no txhais tau hais tias thaum lub kaw lus yuav raug ntsuas thiab tsim los tiv thaiv SCC raws li paub txog qib concentration, qhov tsis ua haujlwm tshwm sim dhau sijhawm raws li kev daws teeb meem sib sau hauv ntau qhov chaw thiab qib concentration hloov pauv sab nraud ntawm qhov pib txiav txim siab kam rau ua.
Thaum ib lub kaw lus twb tau ua haujlwm lawm, kev tswj hwm kev pheej hmoo tau ua kom yuam kev. Ntau yam txheej txheej hlau yuav muab kev tiv thaiv ntxiv tab sis tseem yuav ntxiv lwm txheej ntawm kev saib xyuas qhov nyuaj thiab kev txhawj xeeb.
Kev kho cua sov kuj tseem tuaj yeem txo cov kev ntxhov siab ntxiv los txhim kho kev tiv thaiv thiab tiv thaiv SCC.
Txawm li cas los xij, nws yog ib qho tseem ceeb los xyuas kom meej tias kev kho cua sov tau ua kom raug raws li qhov kub thiab txias yog qhov tseem ceeb ntawm kev tsim cov kev ntxhov siab tawg.
Tsis siv txoj kev kho mob kom zoo tuaj yeem ua rau mob heev uas qhov kev kho mob yog tsim los tiv thaiv.
