1.What yog lub corrosion tsis kam ntawm DC02 hlau nws tus kheej?
Thaum raug huab cua lossis ya raws ntawm chav sov, ib tee xoob ntawm cov hlau oxide (xeb) sai sai rau saum npoo. Qhov kev ua yeeb yaj kiab uas muaj xeb, tsis zoo li cov yeeb yaj kiab hla "ntawm stainless hlau, tsis ua raws li nruj. Hloov chaw, nws tsis tu ncua cov dej noo thiab cov pa, nrawm corrosion ntawm lub hauv paus substrate (hu ua "xeb nthuav dav").
Hu rau dej, ntsev (xws li ib puag ncig hiav txwv ib puag ncig), lossis alkalis (xws li cov roj thiab cov tshuaj ntxuav kom nrawm nrawm dua tus nqi kho mob corrosion. Piv txwv li, hauv ib puag ncig noo thiab qab zib, lub sijhawm corrosion ntawm DC02 cov hlau tuaj yeem luv luv rau ob peb hnub rau ob peb lub lis piam.
2.How qhov chaw tiv thaiv qhov chaw puas cuam tshuam rau corrosion tsis kam?
Liab qab steel (tsis kho): tsis zoo tsis zoo, nquag mus rau xeb; Haum rau luv - sij hawm cia thiab txuas ntxiv tam sim ntawd
Kev Kho Mob Phosphating: ib zaj yeeb yaj kiab phosphate (ntxeem tau) yog tsim nyob rau saum npoo, uas muaj nruab nrab corrosion tsis kam thiab tuaj yeem txhim kho cov nplaum ntawm cov yeeb yaj duab. Nws yog qhov haum rau cov khoom siv hauv tsev thiab lub tsev lag luam sab hauv (yuav tsum tau txuas ntxiv).
Galvanizing (electrogalvanizing / kub - dip falvanizing): kev tiv thaiv kab mob anode (uas muaj cov zoo corrosion. Lub zinc txheej thawj corrodes thiab tiv thaiv cov substrate. Nws yog qhov tsim nyog rau sab nraum zoov me corrosion corrosion (xws li yooj yim hlau nkhaus) thiab cov khoom siv sab hauv ntawm cov khoom siv hauv tsev.
3. Qhov kev siv ib puag ncig ua rau muaj "tiag corrosion tiv taus lub neej"?
Hauv cov chaw ua kom qhuav thiab huv si (xws li thaj chaw sov sab hauv tsev): Cov khoom siv tsis tau muaj xeb (thaum cov khoom siv dawb
Hauv cov chaw ua noj muaj zog (xws li chav ua noj thiab chav dej, thiab thaum lub caij ntuj los nag nyob rau hauv 1-2 asthiv, thiab tsis tau muaj cov phosphated twg kuj tseem muaj xeb tsis pub dhau 1-3 lub hlis.
Hauv kev xeb ib puag ncig (xws li thaj chaw ntug dej hiav txwv (muaj cov ntsev), thiab cov khoom siv roj av (uas muaj cov hmoov av) Qhov chaw pleev xim tsis muaj kev tiv thaiv corrosion tseem muaj kev tiv thaiv kom sai vim yog xim zaj duab xis rhuav tshem.
4.How yuav nws lub corrosion tsis sib piv rau lwm cov hlau?
Zoo dua li: Kub dog dig - {1} {} {polled txias {}} oxidation tus nqi yog qeeb qeeb.
Tsis txaus ntseeg rau: Tsawg {{- Cov Hluav Taws Xob Hlau (xws li Corper thiab Phosphorus tsis muaj 3-5 zaug uas yog DC02 hlau.
Ntau phem dua li: Stainless hlau (xws li muaj 304, ua rau nws muaj xeb ruaj khov, ua haujlwm tsis sib xws ib puag ncig, thaum DC02 hlau tsis muaj lub peev xwm no.
5.Qhov yog cov kev ntsuas tseem ceeb tshaj plaws los txhim kho kev xeb tsis kam ntawm DC02 hlau?
Ua ntej saum npoo -}}}} Cov khoom lag luam kho: Thaum xaiv galvanized lossis phospholated toj lossis phospholated gal02 hlau ncaj qha, zam kev tsis txhob muaj hlau hlau.
Tom qab no txhawb kev tiv thaiv corrosion: pleev xim, tshuaj tsuag, lossis siv cov hlau ove}}}} Cov txheej hlau, kom tau txais cov txheej sib piv thiab tsis muaj qhov khoob.
Ib puag ncig kev cais tawm: Hauv ib puag ncig vaum, Forrosive ib puag ncig (piv txwv li, nruab waterproof npog), lossis tsis tu ncua ntxuav thiab xeb xeb inibitors.
Zam kev sib chwv ncaj qha nrog kev sib cuag corrosive: Tiv thaiv DC02 cov hlau sib txuas los ntawm kev sib chwv ntev nrog cov dej ntsev, acidic lossis alkaline daws teeb meem. Yog raug, huv thiab qhuav lawv kom sai.
