Puas yuav 304 stainless hlau xeb?
Stainless hlau 304 yog ib qho kev tiv thaiv corrosion-resistant steel nrog zoo corrosion kuj. Nws cov kev tiv thaiv corrosion feem ntau suav nrog cov hauv qab no:
1. Zoo oxidation tsis kam:Stainless hlau 304Nws muaj 18% chromium, tsim cov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom chromium oxide zaj duab xis (chromium oxide), uas tuaj yeem thaiv qhov yaig ntawm huab cua, dej, thiab ntau cov xov xwm tsis muaj zog, thiab ua lub luag haujlwm hauv oxidation tsis kam.
2. Kev kho tus kheej ntawm chromium: Thaum stainless hlau 304 raug khawb los yog puas, chromium tuaj yeem ua ke nrog cov pa oxygen los ua chromium oxide, uas txuas ntxiv kho thiab txhim kho corrosion ntawm cov hlau.
3. Molybdenum element nyob rau hauv steel: Stainless hlau 304 muaj ib tug me me ntawm molybdenum caij. Molybdenum tuaj yeem txhim kho qhov corrosion tsis kam ntawm cov hlau rau qee qhov chaw tshwj xeeb (xws li thaj chaw acidic thiab chloride ion ib puag ncig).
4. Inhibition ntawm grain ciam corrosion ntawm hlau: Stainless hlau 304 muaj ib tug qis carbon cov ntsiab lus, uas yuav txo tau segregation ntawm grain ciam teb ntawm hlau thiab txo tau ntawm grain ciam corrosion. Feem ntau hais lus, stainless hlau 304 muaj ntau yam txheej txheem xws li tsim cov chromium oxide zaj duab xis, kho tus kheej, thiab kho cov ntsiab lus ntawm molybdenum thiab cov pa roj carbon monoxide, ua rau nws muaj kev tiv thaiv corrosion zoo thiab tsim nyog siv rau ntau qhov chaw corrosive.
304 stainless hlau phaj yog cov khoom siv zoo corrosion kuj, tab sis nws tsis txhais hais tias nws yuav tsis xeb. Cov hauv qab no yuav yog los ntawm qhov kev xav ntawm kev sib txuas vim li cas, kev nkag siab zoo, thiab kev tshawb fawb nrov.
Dab tsi yog vim li cas 304 stainless hlau daim hlau tuaj yeem xeb?
304 stainless hlau phaj yog tsim los ntawm cov khoom xws li chromium (Cr) thiab npib tsib xee (Ni). Nws cov tshuaj muaj pes tsawg leeg tuaj yeem hnov mob nrog oxygen los ua ib daim duab ntom ntom chromium oxide (Cr2O3), uas tiv thaiv cov khoom los ntawm kev oxidized ntxiv, yog li muaj qhov zoo dua. Corrosion zog. Txawm li cas los xij, cov hauv qab no tuaj yeem ua rau 304 stainless hlau phaj rau xeb: Cov ntsiab lus hlau ntau dhau: 304 stainless hlau phaj muaj qee yam hlau. Yog hais tias cov ntsiab lus hlau yog siab dhau lawm, nws yuav txo nws cov corrosion kuj thiab ua rau nws yooj yim rau xeb.
Deg dampness los yog paug: Yog hais tias qhov saum npoo ntawm 304 stainless hlau phaj yog damp rau lub sij hawm ntev, corroded los ntawm cov tshuaj los yog kuab paug, nws yuav rhuav tshem cov qub chromium oxide zaj duab xis, ua rau lub stainless hlau phaj yuav raug rau huab cua, thiab ces. xeb.
Qhov kub thiab txias ib puag ncig: Hauv qhov kub thiab txias ib puag ncig, cov chromium oxide zaj duab xis ntawm 304 stainless hlau phaj tuaj yeem hloov pauv thiab tsis tuaj yeem tiv thaiv kev nkag mus ntawm oxygen thiab noo noo, ua rau xeb.
Sib cuag nrog lwm cov hlau: Thaum 304 stainless hlau phaj nyob rau hauv kev sib cuag nrog lwm yam hlau, nws yuav ua rau
Ib qho tshuaj tiv thaiv electrochemical tshwm sim, tsim ob peb galvanic, thiab ib qho ntawm cov hlau yuav corroded, ua rau xeb.
Txawm hais tias 304 stainless hlau daim hlau muaj qhov zoo corrosion kuj, lawv yuav inevitably cuam tshuam los ntawm ib puag ncig thiab xeb. Txhawm rau txuas ntxiv nws lub neej kev pabcuam, peb tuaj yeem siv cov kev ntsuas hauv qab no:
Kev tu tsis tu ncua: Ntxuavnto ntawm 304 stainless hlau phajtsis tu ncua kom tsis txhob muaj cov kab mob sib kis thiab ua kom nws qhov chaw huv si thiab du.
Tsis txhob raug cov dej noo ntev ntev: Sim kom tsis txhob nthuav tawm 304 stainless hlau phaj mus rau qhov chaw ntub dej rau lub sijhawm ntev, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias.
Tiv thaiv kev sib cuag nrog lwm yam hlau: Tsis txhob sib cuag ncaj qha ntawm 304 stainless hlau daim hlau thiab lwm yam hlau, thiab siv tshwj xeeb cais gaskets los yog txheej txheej los tiv thaiv galvanic corrosion.
Ua tib zoo saib xyuas thiab saib xyuas: Txheeb xyuas 304 stainless hlau phaj tsis tu ncua, kho qhov kev puas tsuaj uas yuav ua rau xeb raws sij hawm, thiab tswj nws txoj kev ncaj ncees.
Nyob rau hauv luv luv, txawm hais tias 304 stainless hlau daim hlau muaj zoo corrosion kuj, xeb kuj tseem tshwm sim nyob rau hauv tej yam kev mob. Los ntawm kev tu thiab tu kom tsim nyog,kev pab cuam lub neej ntawm 304 stainless hlau daim hlautuaj yeem txuas ntxiv thiab qhov tshwm sim ntawm xeb tuaj yeem txo.
