Kauv cov kav dej, feem ntau muab tso rau sab nraum zoov thiab feem ntau faus hauv av thaum siv, yog qhov ua rau corrosion thiab xeb. Txhawm rau kom ntseeg tau tias tsis muaj kev cuam tshuam hauv cov kav dej, cov kav dej no yuav tsum muaj zog tiv thaiv corrosion.
Thaum cov kav dej tau corroded, lawv tuaj yeem ua rau cov roj thiab cov pa xau, tsis yog cuam tshuam kev thauj mus los xwb tab sis kuj ua rau ib puag ncig thiab ua rau hluav taws kub thiab lwm yam kev phom sij. Ntawm no, kauv yeeb nkab manufacturers qhia txog cov tseem ceeb uas ua rau corrosion ntawm kauv kav:
Kev Tiv Thaiv Corrosion tsis ua haujlwm: Nws yog ib qho tseem ceeb los xyuas kom muaj kev tiv thaiv corrosion zoo thaum lub sij hawm teeb tsa los yog siv cov kav dej los tiv thaiv corrosive kauv steel ncaj qha. Corrosion tshwm sim thaum cov txheej tiv thaiv ntawm cov yeeb nkab puas lawm. Lub detachment ntawm cov txheej tiv thaiv los ntawm cov yeeb nkab nto ib txwm ua rau tsis ua hauj lwm ntawm kev tiv thaiv corrosion. Qhov no qhia txog qhov tseem ceeb ntawm kev xaiv cov kav dej tiv thaiv corrosive thaum lub sij hawm yuav khoom.
Kev cuam tshuam ntawm Cov Txheej Txheem Sab Nraud: Cov ntsiab lus tseem ceeb suav nrog qhov xwm txheej thiab qhov kub thiab txias ntawm cov xov xwm nyob ib puag ncig lub raj xa dej, nrog rau seb cov xov xwm no puas yog corrosive. Qib ntawm kev tshaj tawm corrosivity yog ze ze rau cov kab mob uas muaj nyob hauv cov av. Rau cov kav xa mus ntev, cov av ib puag ncig ua ntau dua. Tsis tas li ntawd, qhov kub ntawm ib puag ncig qhov chaw uas cov kav dej yog nyob rau hauv kuj muaj feem xyuam rau corrosion ntawm kauv kav. Cov kub siab dua ua kom corrosion, thaum qhov kub qis dua nws qeeb.
