Stainless hlau hlau khoom yog dav siv nyob rau hauv niaj hnub kev lag luam thiab domestic lub neej vim lawv corrosion kuj, zoo nkauj thiab huv si khoom. Los ntawm cov khoom siv hauv chav ua noj mus rau qhov chaw ua lag luam, kev txhim kho ntawm cov hlau tsis muaj hlau ua tshuab tsis yog tsuas yog txhawb nqa kev kawm ntawm cov khoom siv science, tab sis kuj muab cov neeg tsim qauv thiab cov kws tsim qauv nrog ntau qhov kev tsim kho tshiab. Cov hauv qab no yog qee cov ntsiab lus tseem ceeb ntawm kev paub hauv kev ua cov khoom siv hlau stainless hlau.
Ua ntej, cov khoom siv
Stainless hlau yog cov hlau-raws li alloy uas muaj tsawg kawg yog 10.5% chromium. Chromium cov ntaub ntawv ntual oxide zaj duab xis nyob rau saum npoo, muab cov stainless hlau zoo heev corrosion. Stainless hlau kuj tseem muaj lwm cov ntsiab lus xws li npib tsib xee, molybdenum, titanium, thiab lwm yam. Qhov sib ntxiv ntawm cov ntsiab lus no tuaj yeem txhim kho corrosion kuj, lub zog thiab weldability ntawm cov khoom.
Thib ob, kev siv tshuab
Cov txheej txheem hlau ua cov hlau tsis muaj steel muaj xws li txiav, sib sau, vuam, kho saum npoo thiab lwm yam. Vim lub hardness thiab kub kho cov yam ntxwv ntawm stainless hlau, kev ua yuav tsum tau tshwj xeeb cov cuab yeej thiab cov txheej txheem tsis. Piv txwv li, laser txiav thiab plasma txiav yog ntau txoj hauv kev rau kev txiav stainless hlau, thaum CNC dabtsi yog khoov tshuab yog tsim nyog rau txoj kev ua haujlwm.
Thib peb, vuam tshuab
Stainless hlau welding yog ib qho kev sib koom ua ke, tab sis tshwj xeeb yuav tsum tau them rau qhov teeb meem oxidation hauv cov txheej txheem vuam.TIG (Tungsten Inert Gas Arc Vuam) thiab MIG (Hlau Inert Gas Shielded Vuam) yog cov cuab yeej siv rau cov hlau tsis muaj steel. welding, lawv tuaj yeem muab cov vuam zoo thiab kev nkag mus zoo.
Plaub, kev kho deg
Cov txheej txheem kho deg rau cov hlau tsis muaj hlau muaj xws li polishing, kos duab, plating, thiab lwm yam. Cov kev kho mob no tsis tsuas yog txhim kho cov tsos ntawm cov khoom zoo nkauj, tab sis kuj ntxiv txhim kho corrosion kuj. Piv txwv li, daim iav polishing tuaj yeem ua rau lub ntsej muag stainless hlau muaj kev cuam tshuam, thaum kos duab kho muab cov nyhuv matte.
Thib tsib, kev kho cua sov
Kev kho cua sov yog ib qho tseem ceeb ntawm kev txhim kho lub cev ntawm cov hlau tsis muaj steel, nrog rau cov tshuaj annealing, quenching thiab tempering. Los ntawm kev tswj cov txheej txheem cua sov thiab cua txias, lub microstructure ntawm stainless hlau tuaj yeem hloov tau, txhim kho nws cov hardness, lub zog thiab toughness.
Thib rau, kev xav txog kev tsim
Thaum tsim cov khoom siv hlau stainless hlau, nws yog ib qho tsim nyog yuav tau xav txog cov txheej txheem ntawm cov khoom siv thiab kev siv ib puag ncig. Piv txwv li, cov teeb meem corrosion hauv zos ntawm stainless hlau (xws li pitting thiab crevice corrosion) yuav tsum tau zam los ntawm kev xaiv cov khoom tsim nyog thiab tsim. Tsis tas li ntawd, cov coefficient ntawm thermal expansion ntawm stainless hlau yog siab, thiab tus tsim yuav tsum coj mus rau hauv tus account qhov kub thiab txias hloov ntawm cov khoom loj.
Xya, Kev Tswj Xyuas Zoo
Kev tswj xyuas zoo ntawm cov khoom siv hlau tsis muaj hlau muaj xws li kev tshuaj xyuas cov khoom, kev soj ntsuam cov txheej txheem thiab cov khoom tiav lawm. Cov txheej txheem kuaj tsis muaj kev puas tsuaj xws li kuaj ultrasonic, kuaj kab hluav taws xob, thiab lwm yam tuaj yeem siv los nrhiav qhov tsis xws luag sab hauv. Thiab kev kuaj corrosion kuj, hardness kuaj, thiab lwm yam yog siv los ntsuas qhov corrosion kuj thiab mechanical zog ntawm cov khoom.
Yim, kev tiv thaiv ib puag ncig thiab sustainability
Stainless hlau yog cov khoom siv rov ua dua tshiab, thiab cov khoom pov tseg los ntawm nws cov khoom thiab kev ua haujlwm tuaj yeem siv tau zoo. Thaum tsim thiab ua cov khoom lag luam stainless hlau, lawv cov yam ntxwv ib puag ncig thiab kev ruaj ntseg yuav tsum raug txiav txim siab los txo qhov cuam tshuam rau ib puag ncig.
Kev ua haujlwm ntawm cov khoom siv hlau tsis muaj steel hlau yog ntau qhov kev qhuab qhia uas suav nrog cov khoom siv science, kev siv thev naus laus zis, tsim kom zoo nkauj thiab cov ntsiab lus ib puag ncig. Kev nkag siab txog cov khoom siv ntawm cov hlau tsis muaj steel, kev siv thev naus laus zis, vuam thev naus laus zis, kev kho deg, txheej txheem kho cua sov, kev xav txog kev tsim, kev tswj kom zoo, kev tiv thaiv ib puag ncig thiab kev ruaj khov thiab lwm cov ntsiab lus tseem ceeb yog qhov tseem ceeb los txhim kho cov khoom zoo, txhawb kev tsim kho tshiab thiab ua tiav. kev tsim kho kom ruaj khov.
