Kev Tshawb Fawb thiab Kev Sib Tham Txog Tshwj Xeeb Anticorrosive Coatings rau Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob thiab Hluav Taws Xob Hluav Taws Xob

Lub tshav kub exchanger yog ib qho cuab yeej uas hloov ib feem ntawm cov cua kub ntawm cov kua dej kub mus rau cov kua dej txias,

Kuj tseem hu ua lub tshav kub exchanger. Thaum tshav kub kub exchangers yog cov cuab yeej siv hauv tshuaj, roj av, lub zog, khoom noj, thiab ntau lwm yam kev lag luam, tuav txoj haujlwm tseem ceeb hauv kev tsim khoom. Hauv kev tsim tshuaj, cov khoom siv hluav taws xob tuaj yeem siv tau ntau dua li cov cua sov, txias, condensers, evaporators, thiab reboilers. Muaj ntau hom kev sib hloov cua sov, tab sis raws li cov hauv paus ntsiab lus thiab cov txheej txheem ntawm kev sib pauv cua sov ntawm cov dej txias thiab cov dej kub, lawv tuaj yeem muab faib ua peb pawg loj: inter phab ntsa hom, hom hybrid, thiab hom regenerative. Raws li kev tsim kho nyob rau hauv lub sijhawm ntev ntawm Beijing Zhisheng Weihua Chemical Engineers, cov khoom siv hluav taws xob feem ntau yog siv nyob rau hauv qhov kub thiab txias (siab lossis pH) ib puag ncig, nrog rau cov qauv zoo corrosion. Kev siv tus nqi ntawm cov khoom siv hluav taws xob sib pauv ncaj qha cuam tshuam rau kev ua haujlwm thiab tus nqi ntawm cov txheej txheem roj refining. Raws li kev txheeb cais, cov khoom siv hluav taws xob sib pauv tau kwv yees li 1/5 ntawm kev nqis peev hauv kev tsim kho chemical engineering. Yog li ntawd, kev siv piv thiab lub neej ntawm cov khoom siv hluav taws xob sib txawv yog cov teeb meem tseem ceeb uas tsim nyog kawm. Los ntawm qhov kev xav ntawm qhov ua rau muaj kev puas tsuaj rau cov khoom siv hluav taws xob, corrosion yog ib qho tseem ceeb heev, thiab corrosion ntawm tshav kub exchangers yog ib qho tshwm sim thoob plaws. Yuav kom daws tau qhov teeb meem corrosion zoo yog sib npaug los daws cov hauv paus kev puas tsuaj rau cov khoom siv hluav taws xob.

Qhov corrosion ntawm tshav kub exchangers feem ntau yog hais txog corrosion ntawm daim hlau. Uniform corrosion thiab localized corrosion yog ob yam loj ntawm corrosion ntawm stainless hlau daim hlau ntawm phaj kub exchangers. impurities, ntsev, gases, thiab kab mob nyob rau hauv nruab nrab ntawm lub tshav kub exchanger yuav ua rau corrosion mus rau lub tubesheet thiab welds. Kev tshawb fawb tau pom tias cov dej muaj dej, txawm tias dej tshiab los yog dej hiav txwv, muaj ntau yam ions thiab yaj cov pa oxygen, cov kev hloov pauv ntawm cov tshuaj chloride ions thiab cov pa oxygen ua lub luag haujlwm tseem ceeb hauv kev xeb ntawm cov hlau. Tsis tas li ntawd, qhov nyuaj ntawm cov qauv hlau kuj tuaj yeem cuam tshuam rau corrosion morphology. Corrosion uas yog concentrated rau ib tug me me cov ntsiab lus ntawm cov hlau nto thiab muaj ib tug ntau dua qhov tob yog hu ua pitting corrosion, los yog me me qhov corrosion los yog pitting corrosion. Kev xeb loj heev tuaj yeem tshwm sim hauv qhov khoob thiab npog thaj chaw ntawm cov hlau nto. Yog li ntawd, qhov corrosion ntawm lub vuam ntawm lub raj phaj thiab lub raj array yog feem ntau pitting corrosion thiab crevice corrosion. Los ntawm sab nraud, yuav muaj ntau cov khoom siv corrosion thiab cov av nyob rau saum npoo ntawm lub phaj phaj, nrog cov npuas ntawm qhov sib txawv ntawm qhov ntau thiab tsawg. Thaum cov dej hiav txwv siv los ua qhov nruab nrab, galvanic corrosion kuj tuaj yeem tshwm sim. Bimetal corrosion kuj yog ib qho tshwm sim ntawm lub raj phaj corrosion. Lub anti-corrosion txheej tshawb fawb engineer ntawm Beijing Zhisheng Weihua Chemical Co., Ltd. Hom corrosion hauv zos feem ntau muaj xws li crevice corrosion, kev nyuaj siab corrosion, thiab hnav corrosion. "Kev puas tsuaj ntawm cov hlau los ntawm cov tshuaj lom neeg lossis electrochemical kev ua ntawm ib puag ncig nruab nrab, feem ntau ua ke nrog lub cev, tshuab, lossis lom, uas yog, los ntawm kev ua ntawm ib puag ncig uas nws nyob."
