Q1: Dab tsi yog cov qauv tsis ua tiav ntawm Q235B kav?
A1: Tsib feem tsis ua tiav hom tshwm sim: uniform corrosion (feem ntau), muaj kev nyuaj siab hauv kev ua haujlwm (ua rau qaug zog), thiab khov kho (ntawm cov khoom kub qis). Weld-ntsig txog kev ua tsis tiav (tsis muaj kev lag luam, he tawg) account rau 40% ntawm kev ua tsis tiav thaum lub tshuab tsis huv.
Q2: Yuav ua li cas thiaj tiv thaiv tsis tau?
A2: Siv peb-pab tiv thaiv peb-kev xaiv (txheej txheem tsim nyog), 2) Cathodic tiv thaiv rau cov kav dej tawg, thiab 3) kev tshawb xyuas / txij nkawm. Tswj ib puag ncig thaum ua tau (dehumidification, kho tshuaj lom neeg). Zam kev txwv dej uas mob nrawm. Siv cov coupons corrosion lossis probes rau kev kuaj ntxov.
Q3: Cov cim ntawm kev ua kom tsis txhob muaj zog poob siab?
A3: Qhov ntsuas thaum ntxov: qhov tshwj xeeb ntawm cov kev ntxhov siab (tshwj xeeb tshaj yog cov kev sib cav sib ceg), hloov pauv hauv cov yam ntxwv kev co, thiab kev tawm tsam ib cheeb tsam. Qaug zog tawg feem ntau pib ntawm Weld ntiv taw, threaded sib txuas, lossis txhawb cov ntsiab lus. Ultrasonic kev kuaj tuaj yeem ntes cov subsurface tawg ua ntej pom cov cim tshwm sim. Txoj kev pab pawg pab txheeb cov tshooj ntau tshaj.
Q4: Yuav ua li cas tsis tiav kev soj ntsuam?
A4: txoj hauv kev ua tiav nrog: 1) Cov ntaub ntawv tsis ua tiav qhov chaw thiab cov khoom siv tshuaj ntsuam / microscolic cov khoom siv, thiab 5) kev ntsuas kev ntxhov siab ntawm cov kab ke. Cov txuj ci siab zoo li sat / uts txheeb xyuas cov txheej txheem bacture thiab cov khoom paug.
Q5: Dab tsi tsim kev ua haujlwm tiv thaiv tsis ua tiav?
A5: Kev coj ua ke muaj xws li: Zam kev sib tw ntse (siv cov hluav taws xob kom zoo (tiv thaiv kev tiv thaiv hluav taws xob kom zoo, kev tiv thaiv kev puas tsuaj rau kev puas tsuaj. Kev tsom xam feagent pab txheeb xyuas cov chaw ntxhov siab siab. Kev siv kev rov ua dua tshiab hauv cov tshuab tseem ceeb qhia tsis tau kev tiv thaiv kev nyab xeeb.
