Rau tus neeg sawv cev passivation ntawm refining system ntawm kev lag luam roj av, lubhlau- clad phaj must use relevant experiments to confirm its practicability. The experimental project has coating function, surface activity, surface solubility, reliability, anti-corrosion, and moisture index. value, continuous fluidity device experiments, etc.
Tag nrho hauv tag nrho, cov desulfurizer rau hlau- clad daim hlau siv hauv kev tsim khoom muaj cov khoom zoo corrosion inhibition thiab kuj ua tau raws li qhov yuav tsum tau ua. Yuav kom tau txais kev siv tiag tiag, ntau yam kev cai tshwj xeeb yuav tsum tau siv ncaj qha.
Hom kev sib cuag retarders Muaj ntau ntau hom desulfurizes, thiab cov txheej txheem corrosion inhibition yog complex. Tsis muaj leej twg thiab tib txoj hauv kev los faib lawv cov txiaj ntsig zoo thiab ua rau muaj kev sib raug zoo ntawm lawv cov qauv molecular thiab cov hauv paus ntsiab lus ntawm kev ua haujlwm, txhawm rau tshawb nrhiav thiab ruaj khov. Nws yog feem ntau siv nyob rau hauv ntau yam lus qhia. Desulfurizers tau muab faib zoo.
Lub hauv paus ntsiab lus ntawm kev tiv thaiv cov nyhuv ntawm desulfurizes ntawm cov ntaub ntawv hlau. Nws yog ib qho tseem ceeb heev nyob rau hauv kev tshawb nrhiav ntawm xeb thiab corrosion kuj. Cov hlau- clad phaj tsis muaj tib lub tswv yim pom zoo nyob rau theem no. Nyob rau theem no, tej zaum yuav muaj cov kev xav hauv qab no: adsorption Basic theory, the basic theory of organic chemistry, the basic theory of coating film, synergistic effect, etc. Qhov tseeb, muaj kev sib raug zoo ntawm cov kev tshawb xav no. Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm txhua qhov desulfurized nyob ntawm seb hom desulfurized, cov qauv tshuaj lom neeg, cov khoom siv hlau yog li ntawd, txhawm rau kom nkag siab zoo txog kev tiv thaiv corrosion ntawm cov hlau clad daim hlau, nws yog ib qho tsim nyog yuav tsum nkag siab tag nrho cov hom thiab dielectric yam ntxwv ntawm desulfurized. Cov txheej txheem corrosion ntawm cov ntaub ntawv hlau hauv cov tshuaj electrolyte yog tsim los ntawm ob hom electrochemical corrosion. Qhov sib txawv ntawm ob lub electrochemical corrosion yog cathodic txaus ntshai thiab tsis zoo electrode txaus ntshai, yog hais tias lub desulfurized muaj peev xwm tswj tau ib los yog ob ntawm cov cathodic thiab tsis zoo txaus ntshai, nws yuav txo tau lub convective tshav kub hloov coefficient.
