Passivation cuam tshuam nrog dipping lub mesh hauv ib me ntsis nitric los yog citric acid da dej kom tshem tawm cov impurities thiab txhim khu kev tiv thaiv chromium - oxide txheej. Cov txheej txheem no tsis "ntxiv" lub zog, tab sis nws tiv thaiv "tsis" ntawm lub zog los ntawm kev ua kom cov khoom tseem tsis zoo rau ib puag ncig kev tawm tsam. Rau ib qho mesh siv nyob rau hauv marine los yog kev kho mob ib puag ncig, passivation yog ib qho yuav tsum tau ua nyob rau hauv cov qauv tsim.

Ntev -ROI lub sij hawm ntawm High-Cov ntaub ntawv muaj zog

Txawm hais tias stainless hlau mesh muaj tus nqi siab dua li cov hlau galvanized lossis cov khoom siv hluavtaws, nws qhov ntev -Lub sij hawm Rov qab los ntawm Kev Lag Luam (ROI) yog qhov zoo dua. Cov "lub zog" ntawm cov khoom siv txhais ncaj qha rau hauv "tus nqi" los ntawm kev txo qhov zaus ntawm kev hloov, txo qis qis rau kev txij nkawm, thiab muab kev nyab xeeb siab dua. Thaum koj suav nrog tus nqi zog ntawm kev hloov lub vaj huam sib luag ua tsis tiav, qhov ua tau zoo ntawm cov hlau tsis muaj steel ua rau nws yog qhov kev xaiv pheej yig tshaj plaws hauv 10 lossis 20- xyoo. Rau cov chaw tsim khoom, qhov no txhais tau tias tsawg dua kev kho thaum muaj xwm txheej ceev; rau architects, nws txhais tau hais tias lub tsev zoo li zoo nyob rau hauv 30 xyoo raws li nws tau ua nyob rau hauv ib hnub. Kev nqis peev hauv qib siab - zoo, lub zog mesh yog kev nqis peev hauv kev ua haujlwm ruaj khov.

Khoom siv zog sib piv (Standard Specs)

Daim ntawv thov -Cov lus qhia tshwj xeeb muaj zog

Nyob rau hauv xaus, lub zog ntawm stainless hlau mesh yog ib tug multifaceted engineering cwj pwm uas extends deb tshaj qhov yooj yim lub cev tsis kam. Nws yog qhov tshwm sim ntawm kev siv thev naus laus zis sib koom ua ke ntawm kev xaiv metallurgical, weave geometry, thiab cov txheej txheem tsim tshwj xeeb. Raws li peb tau tshawb nrhiav, qhov ua tau zoo ntawm 300-series alloys, ua ke nrog cov qauv kev ruaj ntseg ntawm cov woven lossis welded lattice, tso cai rau cov khoom no ua raws li cov xwm txheej uas yuav cuam tshuam yuav luag txhua yam tshuaj ntsuam xyuas. Txawm hais tias qhov kev sib tw tseem ceeb yog siab - siab pom, siab - kev tiv thaiv kev tiv thaiv kev nrawm, lossis kev cuam tshuam rau lub sijhawm ntev ntawm cov dej hiav txwv corrosive, stainless hlau mesh muab cov khoom siv txhim khu kev qha thiab kev kwv yees uas ua kom muaj kev ua haujlwm zoo thiab kev nyab xeeb ntawm tib neeg.

Thaum kawg, tus nqi tseeb ntawm siab - lub zog stainless hlau mesh nyob hauv nws lub sijhawm ntev - rov qab los ntawm kev nqis peev thiab nws kev hloov pauv thoob plaws kev lag luam tseem ceeb. Thaum qhov kev qhia tshwj xeeb yuav tsum muaj kev nkag siab tob txog cov kev ntsuas kev ntsuas - xws li tawg lub zog, cov ntsiab lus tawm los, thiab kev ua haujlwm ntawm shear resistance- qhov tshwm sim yog qhov qis - tu, siab - kev ua tau zoo tivthaiv uas sawv qhov kev sim ntawm lub sijhawm. Los ntawm kev ua raws li cov qauv kev sim thoob ntiaj teb thiab xaiv cov qib tsim nyog rau cov kev ntxhov siab ib puag ncig, cov kws ua haujlwm tuaj yeem xa cov hlau tsis muaj hlau mesh nrog kev ntseeg siab. Los ntawm qhov tob ntawm kev tshawb nrhiav roj mus rau qhov siab ntawm aerospace innovation, cov khoom siv no tseem yog ib qho tseem ceeb ntawm cov qauv kev ncaj ncees, ua pov thawj tias thaum lub zog thiab qhov tseeb yog qhov tseem ceeb, stainless hlau mesh yog qhov kev xaiv meej.
