1. Cov dej seem tom qab ntxuav lub boiler hluav taws xob corrodes cov yeeb nkab tooj liab
Cov tooj liab hluav taws xob cua sov raj ntawm lub boiler hluav taws xob tau corroded thiab perforated tom qab lub caij ntuj sov kaw.
Yog vim li cas: Tom qab lub boiler nres khiav, lub boiler hluav taws xob yuav tsum tau muab ntxuav, thiab cov acidic tshuaj nrog NO₃﹣ ntxiv kom tshem tawm cov nplai. Tom qab ntxuav, cov dej acidic tsis tuaj yeem ntxuav tag nrho nrog dej huv, thiab tseem muaj ib feem ntawm lub boiler uas chemically reacts nrog tooj liab. Hauv cov tshuaj tiv thaiv, Cu+2HNO3 = Cu (NO3) 2+H2, cov khoom siv tooj liab nitrate yog phthalocyanine xiav.
Kev ntsuas kho: Tom qab ntxuav lub boiler fais fab, siv dej huv ntau los ntxuav cov dej acidic.
2. Cov dej tsis zoo ua rau galvanic corrosion ntawm stainless hlau kav
Tom qab plaub lub hlis ntawm kev ua haujlwm, cov yeeb nkab stainless hlau tau raug electrochemically corroded, tab sis cov yeeb nkab tooj liab tseem tsis zoo. Qhov tshwm sim no tsuas yog tshwm sim hauv ob peb thaj chaw xws li Gaoqing Cangzhou. Tom qab kev txheeb xyuas, nws yog qhov tshwm sim ntawm cov dej tsis zoo.
3. Cov hlau nyob txuas nrog lub plhaub, ua rau hluav taws xob thiab tuag
Cov da dej hluav taws xob tau nruab rau lub caij ntuj no. Nws tsis tau siv vim nws txias heev. Thaum lub caij ntuj sov, ib tug neeg raug hluav taws xob thiab tua. Tom qab kev soj ntsuam, cov rwb thaiv tsev thiab siab tsis kam ntawm cov hluav taws xob cua sov raj ua tau raws li cov qauv, thiab lwm yam kev tswj ntawm cov da dej kuj zoo li qub. Thaum kawg, nws tau pom tias cov xaim nyob, cov xaim nruab nrab, thiab cov xaim hauv av hauv chav nkag tau thim rov qab. Qhov laj thawj tiag tiag yog thaum Lub Caij Nplooj Ntoos Hlav, cov hluav taws xob sab nraud tau kho thiab cov hluav taws xob txuas tsis raug rau cov hlau nyob.
