1 Raws li Acid Mist Inhibitors
Thaum lub sij hawm pickling, hydrochloric acid, sulfuric acid, los yog nitric acid inevitably hnov mob nrog cov hlau substrate thaum reacting nrog xeb thiab nplai, generating tshav kub thiab ua kom muaj ntau cov kua qaub pos huab. Ntxiv cov surfactants rau cov tshuaj pickling, vim qhov kev ua ntawm lawv pawg hydrophobic, tsim ib qho kev taw qhia, insoluble linear zaj duab xis txheej rau saum npoo ntawm cov tshuaj pickling. Siv cov foaming kev txiav txim ntawm surfactants, acid pos huab volatilization yuav suppressed. Ntawm chav kawm, corrosion inhibitors feem ntau ntxiv rau cov kev daws teeb meem, uas txo cov hlau corrosion thiab txo hydrogen evolution, yog li sib raug zoo txo cov kua qaub.
2 Raws li kev sib xyaw Pickling thiab Degreasing Cleaning
Nyob rau hauv kev lag luam khoom siv tshuaj ntxuav tu, yog hais tias cov fouling muaj roj Cheebtsam, alkaline ntxuav yog ua ntej kom ntseeg tau tias pickling zoo, ua raws li los ntawm acid tu. Yog hais tias ib tug npaum li cas ntawm degreasing tus neeg saib xyuas, feem ntau nonionic surfactants, yog ntxiv rau cov pickling tov, ob kauj ruam yuav muab ua ke rau hauv ib tug txheej txheem. Tsis tas li ntawd, cov tshuaj ntxuav tu feem ntau muaj sulfamic acid thiab muaj qee qhov nyiaj ntawm surfactants, thiourea, thiab inorganic ntsev, uas yog diluted nrog dej ua ntej siv. Hom tshuaj ntxuav no tsis yog tsuas yog muaj cov xeb zoo heev thiab kev tshem tawm thiab kev tiv thaiv corrosion tab sis kuj tseem tshem tawm cov roj ib txhij.
