304 simbi isina tsvina gobvu-yakavezwa chubhuweld musiyano pamberi uye pashure pepamusoro kurapwa uye kugadzirisa zvinoratidza kuti: nzira iyi inogona kubvisa chiyero uye hasha ruvara.

Kana vanhu vakasimudza iyo 304 simbi isina tsvina yakakora-walled chubhu pamusoro oxide layer yechromium oxide yemukati, chimiro cheiyo oxide layer mushure mekugadzirisa, unogona kuvandudza zvakanyanya kuita ngura kwe304 simbi yakakora-yakavakirwa chubhu pamusoro.Nemakemikari ekurapa nzira dzekuwana 304 simbi gobvu-yakavakirwa chubhu yekuvandudza kushora kwepasi mumatanho maviri.Kunyangwe 304 simbi isina simbi gobvu-yakavakirwa chubhu weld neiyi nzira inogona zvakare kushandiswa kuvandudza kwayo kusaora.

Kana iyo 304 simbi isina tsvina yakakora-yakavakirwa chubhu pamusoro pecorrosion kuramba isina kukwana, nyanzvi yekurapa pamusoro pePoligrat Munich kambani yakagadzira Polinox Protec TC tekinoroji inogona kukubatsira kugadzirisa dambudziko iri.Muchina wemuchina uyu uye vatengesi vemakemikari vakagadzira tekinoroji yekuvandudza nickel, molybdenum uye chromium austenitic alloy zvinhu, nekudaro vachivandudza kushorwa kwe304 simbi isina gobvu-yakavakirwa chubhu pamusoro.Kuburikidza nematanho maviri anogona kuwedzerwa 304 Stainless simbi gobvu-walled chubhu pamusoro oxide layer yekurasa kuramba.

Danho rekutanga mukushandiswa kwemvura-based organic solution ye304 Stainless steel gobvu-walled chubhu pamusoro inogadziriswa pamusoro.Kurapa kwepamusoro uku kuchapedza 3 ~ 5h.Munguva ino, bvisa iyo oxide layer kubva pamusoro pechikamu chesimbi, nekuderedzwa kwesimbi, chromium uye iron ratio yakawedzera kubva pa6% kusvika 8%, kune basa rinoshanda mukuvandudza kusimba kwekuora.

Danho rechipiri rekugadzirisa chimiro chepamusoro oxide layer.Izvi zvinowedzera kunatsiridza kusadzivirirwa kwecorrosion kwepamusoro oxide layer.Inokanganisa chimiro chepamusoro oxide layer idanho rekurapa kupisa kwe: zvinoenderana nerudzi rwealloy uye kupisa kurapwa kwekristaro lattice yechinhu chiri mumhepo pa140.℃~ 200℃mu.
