1, Rau lub ionic los yog molecular lub xeev yaj nyob rau hauv dej impurities ntawm lub tshav kub exchanger txaus ntshai
Calcium ntsev: yog lub ntsiab tivthaiv ua rau lub phaj kub exchanger scaling. Cov ntsev yog ib qho nyuaj, crystalline nplua scale, xoob qauv, adhesion yog me me, yog ib tug kuj xoob av nkos slag, sib koom los ntawm cov dej nrog mus, txawm yog txuas mus rau lub rhuab nto kuj yog heev yooj yim mus tshem tawm. Sodium ntsev: Nacl yuav ua kom lub corrosion ntawm cov phab ntsa hlau, Na2So4 cov ntsiab lus siab dhau lawm yuav cuam tshuam rau kev nyab xeeb ntawm cov khoom siv, NaHCo3 nyob rau hauv qhov kub thiab txias, nws yuav decomposed mus rau hauv ib tug xov tooj ntawm cov khoom uas tshwm sim los ntawm hlau grain puas.
2, Rau lub xeev colloidal impurities ntawm lub tshav kub exchanger muaj kev phom sij
Feem ntau cov hlau sib txuas, nws yuav tsim cov nplai hlau. Cov kab mob qee zaum rov qab los thaiv cov raj xa dej, tab sis kuj nyob rau ntawm phaj corrosion. Kuj tseem muaj cov sludge thiab slime nplai, thiab lwm yam yuav ua rau muaj kev thaiv thiab corrosion ntawm cov kav dej.
3, Dissolved oxygen gas tshav kub exchanger txaus ntshai
Cov pa oxygen yog qhov tseem ceeb tshaj plaws uas ua rau corrosion ntawm cov khoom siv hluav taws xob sib hloov, thaum lub corrosion yog concentrated nyob rau hauv qee qhov chaw ntawm cov hlau nto, uas ua rau hauv cheeb tsam corrosion. Localized corrosion yog ceev, yooj yim rau xeb los ntawm, pitting yog localized corrosion nyob rau hauv lub phaj kub exchanger.
Los ntawm cov saum toj no, lub phaj kub exchanger siv nyob rau hauv cov dej zoo yog heev teeb meem rau nws, nyob rau hauv kev siv ntawm cov khoom, peb yuav tsum ntxiv dag zog rau qhov tseem ceeb ntawm kev ua hauj lwm zoo ntawm tshav kub exchanger decontamination raws li zoo raws li anticorrosion, tsis tsuas yog yuav txhim khu lub kev ua haujlwm ntawm kev ua haujlwm kuj tseem tuaj yeem txuas ntxiv lub neej kev pabcuam ntawm cov khoom siv hluav taws xob, kom koj tuaj yeem txuag tau tus nqi ntawm kev nqis peev.
