Puas muaj kev sib txuas ntawm daim ntawv thov ntawm Stainless Hlau Welded Pipes hauv Nuclear Fais Fab thiab Passivation?

Feem ntau, txhawm rau txhim kho corrosion kuj ntawm stainless hlau welded kav, ob txoj kev yog feem ntau siv:passivation thiab electrolysis.Rau stainless hlau welded kav siv nyob rau hauv nuclear fais fab nroj tsuag, kev tiv thaiv corrosion feem ntau muaj kev kho mob passivation (siv stainless hlau passivation tov).Passivation yog txheej txheem tshiab ua lwm txoj hauv kev tiv thaiv lub cev xeb.Lub hauv paus ntsiab lus suav nrog kev siv cov tshuaj oxidizing hauv cov tshuaj passivation (stainless steel passivation solution) los hloov cov hlau ions ntawm cov hlau nto rau hauv lub xeev passive.Qhov no zoo ncua hlau corrosion.Passivation yog cov tshuaj tiv thaiv microchemical uas tsis hloov cov qauv molecular ntawm cov khoom.Nws tsuas yog muab cov pa oxygen nrog cov khoom siv hlau hauv cov khoom siv, ua cov hlau oxide.Cov oxide txheej no nyob rau hauv lub xeev passive, ua raws li ib tug barrier ntawm cov hlau thiab corrosive nruab nrab, tiv thaiv kev sib cuag ncaj qha thiab txwv tsis pub cov hlau los ntawm dissolving, ua tau raws li qhov xav tau kev tiv thaiv corrosion.

EST Chemical Grouptau tsis tu ncua innovating, daws passivation (stainless hlau passivation tov) thiab kev sib tw tiv thaiv xeb rau cov neeg siv khoom.Peb muab cov khoom zoo, txiav-ntug thiab muab tag nrho cov txheej txheem passivation kev daws teeb meem kom tau raws li qhov tshwj xeeb xav tau ntawm cov neeg siv khoom.
