Yog tias cov kev cuam tshuam no tsis raug kaw los yog ntws tawm, cov dej tsis zoo tuaj yeem nyob hauv kev sib cuag nrog lub mesh rau lub sijhawm ntev. Sij hawm dhau mus, qhov no ua rau muaj kev xeb hauv cheeb tsam uas nyuaj los xyuas kom txog thaum muaj kev puas tsuaj loj. Crevice corrosion yog qhov txaus ntshai tshwj xeeb vim tias nws nce sai sai thaum pib thiab tuaj yeem cuam tshuam cov qauv kev ncaj ncees yam tsis muaj cov cim ceeb toom pom tseeb.

Kev txiav txim siab tsim qauv yog qhov tseem ceeb rau kev tiv thaiv kev sib tsoo- ntsig txog xeb. Kev tso dej tawm, zam kev sib tshooj nruj, siv cov khoom siv sib xws, thiab xaiv cov fasteners tsim nyog txhua tus txo kev pheej hmoo. Nyob rau hauv ib puag ncig nruj, cov qib alloy siab dua xws li 316L lossis kev kho saum npoo zoo li electropolishing tuaj yeem txhim kho kev tiv thaiv ntxiv. Kev xav txog kev teeb tsa thiab kev tsim qauv tsuas yog ib qho tseem ceeb xws li kev xaiv cov khoom siv kom ntseeg tau ntev -lub sij hawm corrosion tsis kam ntawm stainless hlau mesh.

Stainless hlau mesh tsis xeb yooj yim, tab sis nws tsis muaj kev tiv thaiv corrosion. Nws txoj kev tiv thaiv xeb yog nyob ntawm kev sib cuam tshuam ntawm cov khoom siv qib, qhov chaw saum npoo, ib puag ncig raug, thiab kev ua haujlwm. Cov yam ntxwv xws li chloride concentration, av noo, kub hloov pauv, kev puas tsuaj, thiab kev tu tsis txaus tuaj yeem cuam tshuam cov txheej txheem tiv thaiv kev tiv thaiv ntawm stainless hlau. Thaum cov txheej txheem no cuam tshuam, kev txhim kho hauv cheeb tsam xws li pitting, crevice corrosion, lossis tshuaj yej staining tuaj yeem tshwm sim-txawm tias nyob rau siab- zoo stainless hlau mesh. Kev nkag siab txog cov txheej txheem no yog qhov tseem ceeb rau cov engineers, fabricators, thiab cov neeg siv kawg uas tso siab rau stainless hlau mesh hauv kev pom, dej ntws, architectural, thiab industrial systems.

Tiv thaiv xeb hauv stainless hlau mesh yog qhov kawg ntawm kev xaiv kom raug, ua kom raug, thiab kev saib xyuas lub luag haujlwm. Xaiv cov qib uas tsim nyog (xws li 316 lossis 316L rau kev ua phem rau sab nraum zoov lossis hauv dej hiav txwv), siv cov txheej txheem txiav thiab ua kom tiav, thiab siv tom qab- kev kho cov khoom siv xws li passivation lossis electropolishing tuaj yeem txuas ntxiv lub neej kev pab cuam. Qhov tseem ceeb sib npaug yog kev tsim qauv tsim thiab kev saib xyuas niaj hnub, suav nrog kev tso dej kom zoo, zam kev sib cuag galvanic, thiab kev tu ncua sij hawm kom tshem tawm cov kab mob. Thaum cov xwm txheej no tau hais txog qhov tseeb, stainless hlau mesh tuaj yeem xa mus ntev - lub sij hawm corrosion kuj, kev ntseeg tau ntawm cov qauv, thiab kev ua tau zoo ib yam -txawm tias nyob rau hauv ib puag ncig xav tau.
