Corrosion Rishance

Iyo Corrostion Kudzvinyirira ye136 Simbi isiri nani pane iyo yeiyo 304 Simbi isina simba, uye ine yakanaka kurwisa mukugadzira maitiro ehuku uye pepa. Uyezve, simbi isimbi 316 inodzivirirawo kuyerera nemakungwa uye nehasha maindasitiri emuindasitiri.

Kazhinji, hapana mutsauko wakawanda pakati pegumi nemakumi matatu nesimbi isina simba uye 316 simbi isina tsvina maererano nemakemikari kurwisa, asi kune misiyano mune mamwe ma media.

Simbi isina tsvina yakatanga kuvandudzwa yaive 304, iyo inoerera yekuisa corrosion iri pasi pemamwe mamiriro. Kuwedzera yakawedzera 2-3% molybdenum inoderedza uku kunzwa uku, uye nekudaro akazvarwa. Uye zvakare, iyi yakawedzera molybdenum inogona kuderedza kuparadzira kweimwe inopisa organic acids.

316 Simbi isiriyo yave kuita zvimwe zvinhu mune zvekudya uye indasitiri yekuvhuvhuta. Nekuda kwekushomeka kwepasi rose kwe molybdenum uye yakakwira nickel zvirimo mune 316 simbi yesimbi, 316 simbi isina kubhururuka kupfuura makumi matatu nesimbi.

Piting Corroson chiitiko chinonyanya kukonzerwa nekuposaniswa pamusoro pechiso cheStanless Simbi, iyo isingakwanise kuumba denderedzwa re chromium oxide nekuda kwekushayikwa kweokisijeni.

Kunyanya mumavharu madiki, mukana wekuiswa paValve Plate idiki kwazvo, saka kudzora kudzora hakuwanzoitika.

Nekuda kwekushandiswa kwakawanda kwesimbi yesimbi isina simba, vanhu vane fungidziro isiriyo yekuti zvese zvisina simba zvisina mashanga hazvisi zvemaginnet. ZveAustenitic Stainless Simbi, inogona kunzwisiswa seNzvimbo Isina Kugadziriswa Simbi Yakatemwa. Asi 304 yakagadziriswa nekudziya kwekugadzira ichave imwe magineti. Kune yakakandwa simbi, kana iri 100% Austenitic Stainless Simbi, haisi yemagineti.

 

 

 

Iyo Corrostion Kudzvinyirira kweAustenitic Stainless Simbi inouya kubva kune inodzivirira chromium oxide layer yakagadzirwa pane yesimbi nzvimbo. Kana zvinyorwa zvacho zvichinge zvapiswa kune tembiricha yakakwira ye450 kusvika ku900 degree, chimiro chekuchinja kwezvinhu, uye chromium carbides fomu pamwe neCrystal EdSstal EdSTALE ECEPS. Nenzira iyi, denderedzwa rekudzivirira reChromium humbowo harigone kuumbwa nemucheto wekristaro, zvichikonzera kuderedzwa kupesana. Uku kurapa kunonzi "kuwirirana kuparadzaniswa".

Semhedzisiro, 304l simbi isina tsvina uye 316l isina simba isina simba yakagadziriswa kurwisa kuonga uku. Vese vari vaviri 304l Stainless Simbi uye 316l Stainless Simbi ine yakaderera carbon zvemukati nekuti iyo kabhoni yezvinyorwa yakaderedzwa, saka hakuzove neChromium Carbide uye hapana kuyamwisa carosion.

Izvo zvinofanirwa kucherechedzwa kuti zvakakwirira zvekunyepedzera kuyamwisa corrosis hazvireve kuti isiri- kuderera kabhoni zvinhu zvinonyanya kuitika kuCorros. Uku kunzwa uku kwakawedzerawo muKigine -

Ndokumbira utarise kuti chiitiko ichi chinokonzerwa nekudziya kwakanyanya (450℃-900 degree). Kazhinji kutengesa ndiyo yakakonzera kukonzera kusvitsa uku kupisa. Zvechigaro zvinyoro-nyoro zvigunwe zvemakonzo zvakawandisa hazvireve kuenda neyakajeka kuenda neyakaderera carbon stainless sezvo isu tisingarambidzi pane iyo disc, kunyangwe vazhinji vakatsanangurira vachadana 304l kana 316l.
