Cov tshuaj pickling siv nyob rau hauv cov txheej txheem pickling ntawm stainless hlau feem ntau yog ib tug sib tov ntawm ntau yam acids, mas sulfuric acid, nitric acid thiab hydrofluoric acid. Cov kua qaub sib xyaw no yog corrosive thiab oxidizing, thiab qhov kub ntawm qhov nruab nrab corrosive kuj tseem siab. Siab, cov no tau muab cov kev xav tau siab rau kev tiv thaiv corrosion ntawm cov khoom siv tiv thaiv- corrosion. Txawm li cas los xij, tom qab lub stainless hlau reactor yog pickled, passivation yuav tshwm sim. Cov tshuaj tau piav qhia hauv qab no:
Muaj ntau yam khoom siv los tiv thaiv-cov khoom siv corrosion tsim nyog rau pickling stainless hlau reactors, ntawm cov epoxy resin thiab nws cov hloov kho resin zoo. Lub hauv paus ntsiab lus ntawm stainless hlau pickling yog siv cov kua qaub kom tshem tawm cov tawv nqaij oxide ntawm cov hlau tom qab pretreatment, tshem tawm cov hlau ions ntawm qhov chaw, thiab ua kom nws muaj kev ua tiav zoo.
Cov ntaub ntawv ntawm cov khoom siv pickling muaj xws li siv ntxhua khaub ncaws, raj ntxhua khaub ncaws, phaj ntxhua khaub ncaws, kab ntxhua khaub ncaws, thiab lwm yam. Txawm li cas los xij, tsis muaj teeb meem dab tsi ntawm cov txheej txheem pickling, cov txheej txheem stainless hlau pickling ntau lawm kab muaj zog corrosion nyob rau hauv tag nrho cov kev sib txuas los ntawm kev tsim khoom rau cov dej khib nyiab thiab cov roj khib nyiab rov qab. qhov system. mob.
Yog li ntawd, kev xaiv cov khoom siv los tiv thaiv-corrosion yog ncaj qha ntsig txog kev siv cov khoom siv ib txwm muaj, cov chaw ua haujlwm hauv tsev, trenches, thiab kev tiv thaiv ib puag ncig rov qab rau cov dej khib nyiab thiab cov pa phem. Kev tiv thaiv -corrosion ntawm hauv pem teb thiab cov khoom siv ntawm stainless hlau pickling cov kab ntau lawm yog tsim los ntawm cov khoom siv FRP, thiab cov khoom siv tseem ceeb (resin) ntawm FRP yog tus yuam sij ncaj qha los txiav txim siab txog kev tiv thaiv - corrosion nyhuv. Yog li ntawd, kev xaiv ntawm resin ncaj qha cuam tshuam rau kev tiv thaiv -corrosion nyhuv. lub neej.
