Theoretical Paub ntawm Stainless Hlau Yeeb Nkab

Stainless hlau yeeb nkab yog ib hom hollow ntev cylindrical hlau.Nws lub peev xwm ntawm daim ntawv thov yog siv los ua lub raj xa dej.Nws yog tsuas yog siv nyob rau hauv industrial kis pipelines xws li roj av, tshuaj kev lag luam, kev kho mob, zaub mov, lub teeb kev lag luam, mechanical instruments thiab mechanical structural Cheebtsam.Stainless hlau kav yog ua los ntawm steel billets ntawm acid thiab kub resistant qib los ntawm cua sov, perforation, sizing, kub dov thiab txiav.Qhov tseeb, tsis muaj cov khoom tuaj yeem tiv thaiv corrosion tshwj tsis yog tias nws nyob rau qee qhov xwm txheej hnyav.Yog tias peb lub phaj stainless hlau yog corroded, nws yuav cuam tshuam rau nws qhov kev siv.Yog li ntawd, peb tseem yuav tsum tau ua qee yam kev tiv thaiv kom tsis txhob muaj qhov xwm txheej no.Tam sim no cia peb nkag siab txog yam uas ua rau corrosion ntawm stainless hlau daim hlau?

(1) Electrochemical corrosion:Qhov khawb tshwm sim los ntawm kev sib cuag ntawm stainless hlau phaj thiab carbon steel qhov chaw, thiab tom qab ntawd tsim cov galvanic cell nrog corrosive nruab nrab, uas yuav tsim electrochemical corrosion.Yog tias cov nyhuv pickling passivation tsis zoo, cov zaj duab xis passivation ntawm lub phaj yuav tsis sib npaug los yog nyias dhau, uas yog ib qho yooj yim los tsim electrochemical corrosion, slag txiav, txaws thiab lwm yam xeb uas txuas nrog rau lub phaj, thiab Tom qab ntawd tsim ib lub cell galvanic nrog corrosive nruab nrab, uas ua rau electrochemical corrosion.Pickling thiab passivation tu tsis huv, ua rau cov khoom siv tshuaj corrosion ntawm cov khoom seem thiab cov khoom seem thiab cov phaj, thiab tom qab ntawd electrochemical corrosion nrog lub phaj.

(2) Raws li tej yam kev mob, ntau greasy av, plua plav, kua qaub, alkali, ntsev, thiab lwm yam uas txuas rau saum npoo ntawm stainless hlau daim hlau yuav hloov mus rau hauv corrosive media, uas yuav hnov ​​​​mob chemically nrog ib co Chemical Cheebtsam nyob rau hauv daim hlau, uas ua rau cov tshuaj corrosion thiab xeb.Kev ntxuav, pickling thiab passivation tsis huv txaus, ua rau khaws cia cov kua seem, uas ncaj qha corrodes lub phaj.Qhov saum npoo ntawm lub phaj yog khawb, uas ua rau kev puas tsuaj ntawm cov zaj duab xis passive, yog li kev tiv thaiv muaj peev xwm ntawm lub phaj yog txo, thiab nws yooj yim rau kev cuam tshuam nrog tshuaj lom neeg.
