Stainlesssteel vuam meshmuaj zog tiv thaiv corrosion thiab anti-oxidation yam ntxwv.Siv rau kev tiv thaiv machinery, kev lag luam, kev ua liaj ua teb, kev tsim kho, thiab lwm yam Stainless hlau hlau vuam mesh xaiv zoo stainless hlau hlau, los ntawm precision tsis siv neeg tshuab vuam, cov khoom net nto du, cov qauv ruaj khov, muaj zog corrosion kuj.
Nitric acid point test ntawm stainlesssteel welding mesh.Ib qho tseem ceeb feature ntawm stainless hlau raj yog lawv qhov kev tiv thaiv corrosion rau concentrated thiab dilute nitric acid.Cov cuab yeej no tso cai rau nws yooj yim sib txawv ntawm feem ntau lwm yam hlau lossis alloys.Txawm li cas los xij, high carbon 420 thiab 440 steels yog me ntsis corroded nyob rau hauv nitric acid point test, thiab non-ferrous hlau yuav corroded tam sim ntawd thaum lawv ntsib concentrated nitric acid.Dilute nitric acid yog corrosive rau carbon hlau.
Kev sim ntawm sulfuric acid immersion stainless hlau xaim mesh.Qhov kev sim no tau siv los paub qhov txawv ntawm 302 thiab 304 los ntawm 316 thiab 317. Qhov kev txiav ntug ntawm cov qauv yog cov av zoo thiab tom qab ntawd soaked hauv nitric acid nrog lub ntim concentration ntawm 20-30% thiab kub ntawm 60-66.℃rau ntxuav thiab passivation rau ib nrab ib teev.Qhov ntsuas sulfuric acid hnyav nrog qhov ntim ntawm 10% yog rhuab mus rau 71℃.Thaum 302 thiab 304 thawj zaug nkag mus rau qhov kev daws teeb meem no, lawv tau nrawm nrawm thiab tsim cov qauv nrog cov khoom paub txog kev sib piv.Nyob rau hauv txoj kev no, qhov kev sim yuav ua tau ntau dua.
Copper sulfate qhov chaw kuaj rau stainlesssteel vuam mesh.Qhov kev ntsuam xyuas tooj liab sulfate yog qhov yooj yim tshaj plaws thiab yooj yim tshaj plaws kom paub qhov txawv ntawm cov pa roj carbon zoo tib yam los ntawm txhua hom stainless hlau.Qhov concentration ntawm tooj liab sulfate tov yog 5 ~ 10%.Ua ntej qhov ntsuas qhov ntsuas, qhov chaw xeem yuav tsum tau ntxuav kom huv si ntawm cov roj lossis ntau yam impurities, thiab ib qho chaw me me yuav tsum tau polished nrog cov ntaub mos muag, thiab tom qab ntawd yuav tsum tau siv ib lub raj mis los tso cov tshuaj tooj liab sulfate rau hauv qhov chaw huv.Ordinary carbon steel los yog hlau tsim ib txheej txheej ntawm tooj liab nyob rau hauv ib lub vib nas this, thaum lub saum npoo ntawm stainless hlau tsis tso tooj liab los yog tooj liab xim.
Kev txhais lus software txhais lus, yog tias muaj qhov yuam kev thov zam txim.
