Vim li cas 316L stainless hlau tsis muaj dej tsis muaj lub tes tsho muaj kev tiv thaiv corrosion zoo dua?

Cov khoom siv ntawm stainless hlau hloov tau lub tes tsho yog 304,316L, nws cov yam ntxwv ntawm cov khoom siv yog qhov ruaj khov, qhov yooj ntawm cov hlau kuj zoo heev, qhov tseem ceeb yog tias nws cov corrosion kuj zoo dua, nyob rau hauv qhov chaw ntub dej thiab txias, los yog nyob rau hauv lub cheeb tsam nrog cov kev cai tiv thaiv corrosion, nrog lub tes tsho hlau stainless hlau tsis muaj dej, tom qab ib qho kev daws teeb meem, muaj kev tiv thaiv zoo heev thiab tiv thaiv corrosion.

1. Hauv qab dej

Thiab nyob rau hauv lub pas dej purification ntawm cov nroj tsuag dej, stainless hlau saj zawg zog waterproof lub tes tsho Stainless hlau waterproof lub tes tsho yog siv, uas yog, vim hais tias nws tsis yooj yim rau xeb, los yog tus nqi ntawm xeb kuj qeeb.Nyob rau hauv tag nrho cov txheej txheem kev tsim kho ntawm qhov project tshwj xeeb, yog tias cov yeeb nkab phab ntsa tsis hloov nrog stainless hlau waterproof casing, kom cov phab ntsa thiab cov kav dej tam sim ntawd kov, ua ntej, lub zog ntawm phab ntsa nyob rau sab saum toj ntawm cov kav dej yog yooj yim heev. , ua rau lub deformation los yog txawm rupture ntawm lub raj xa dej, qhov thib ob, cov xau ntawm cov kav dej ua rau kev tso tawm ntawm phab ntsa kuj yuav ua rau muaj kev puas tsuaj loj rau cov kav dej.Nws tsis yog qhov nyuaj kom pom tias qhov tseem ceeb npaum li cas ntawm stainless hlau waterproof casing yog.

2. Hauv huab cua

Qhov saum npoo ntawm cov khoom hlau yuav hnov ​​​​mob nrog oxygen nyob rau hauv cov huab cua los ua ib qho oxide zaj duab xis rau ntawm qhov chaw.Qhov txawv yog tias cov hlau oxide tsim nyob rau saum npoo ntawm cov pa roj carbon zoo tib yam yuav txuas ntxiv mus rau oxidize, ua rau cov corrosion txuas ntxiv mus ntxiv thiab nws thiaj li tsim qhov.Qhov saum npoo ntawm 316L stainless hlau welded yeeb nkab kuj yuav hnov ​​​​mob nrog oxygen, tab sis vim nws cov ntsiab lus chromium siab, qhov corrosion kuj ntawm stainless hlau nyob ntawm chromium.Thaum cov ntsiab lus ntawm chromium ntxiv nce mus txog 10.5, qhov atmospheric corrosion kuj ntawm cov hlau yog txhim kho, thiab cov ntsiab lus chromium ntawm 316L stainless hlau welded yeeb nkab yog ntau dua 17. Qhov laj thawj yog vim li cas thaum hlau alloyed nrog chromium, hom oxide nto. yog yoog kom zoo li hom tsim ntawm cov hlau ntshiab chromium.Qhov no nruj nreem txuas nrog chromium-nplua nuj oxide tiv thaiv saum npoo ntawm oxidation ntxiv.Cov txheej oxide no nyias nyias uas lub ntuj ci ntawm cov hlau tuaj yeem pom los ntawm nws.
