Kev Taw Qhia rau Cov Khoom Tooj Corrosion:
Corrosion khoom nyob rau hauv huab cua
Thaum tooj liab maj mam oxidizes rau hauv huab cua, nws lub chaw tiv thaiv nws yog BIX) COPLONATE (CU₂ (Oh) ₂ces₃), uas yog xim ntsuab hauv cov xim. Nov yog cov khoom lag luam corrosion feem ntau ntawm tooj liab. Hauv huab cua noo, qhov no cov tshuaj ntsuab maj mam tshwm ntawm qhov chaw tooj liab.
Corrosion khoom hauv Sulphur -} muaj ib puag ncig
Yog tias tooj tooj liab raug rau tus neeg sulphur -}} muaj ib puag ncig, dub tooj liab sulfide (CUS) yuav ua tau. Tooj liab sulfide yog ib txwm tsim thaum tooj liab tuaj rau hauv kev sib cuag nrog cov neeg sulphur- muaj cov tshuaj xws li hydrogen sulfide.
Corrosion khoom nyob rau hauv chlorine -} muaj ib puag ncig
Hauv chlorine -}} muaj cov chaw ib puag ncig, corrodes los ua xim ntsuab chloride (cucl₂). Tooj liab chloride tuaj yeem tshwm sim Bluish - green, nyob ntawm nws cov kev xav thiab daim ntawv. Tsis tas li ntawd, nyob rau hauv cov kev mob corrosion sib txawv, tooj liab cov khoom lag luam yuav ua rau lwm cov xim thiab cov xim. Piv txwv li, hauv qee qhov chaw ib puag ncig, corrosion cov khoom yuav tshwm sim hauv ntau cov xim, xws li xim av lossis xiav.
Yuav ua li cas txhim kho lub corrosion tsis kam ntawm tooj liab?
1. Nto Kho Mob
Passivation: Tus txheej txheem tshuaj lom neeg ua rau cov yeeb yaj kiab uas hla dhau ntawm cov tooj liab saum npoo av. Cov yeeb yaj kiab no tiv thaiv kev tawm tswv yim xws li oxygen thiab ya raws los ntawm kev tuaj cuag nrog tus tooj liab nto, li txhim kho corrosion. Piv txwv li, kev kho mob nrog cov neeg sawv cev sib tw dhau xws li chromates thiab benzotriazole tuaj yeem txhim kho tooj liab lub xeb kev ib puag ncig.
Electroplating lossis Tshuaj Plating Plating: A corrosion - ionistant hlau lossis alloy, xws li Nickel, lossis zinc, tuaj yeem thov rau tus tooj liab. Cov txheej txheej no ua yeeb yam ntawm lub cev lub cev, tiv thaiv cov xov xwm corrosive los ntawm kev tawm tsam tus tooj.
Electroplating nrog npib hluav taws xob txhim kho tooj liab txoj kev tsis kam nyob rau hauv cov chaw noo noo, thaum chromium plating txhim kho thiab corrosion tsis kam. Chemically plating nrog nickel - phosphorus alloys kuj tseem muaj kev tiv thaiv corrosion zoo nkauj ntxiv.
Organic txheej: ib qho txheej txheem epoxy, xws li epoxy cob lossis polyurethane, yog thov rau tus tooj liab saum. Cov txheej txheem organic muab ib qho teeb meem rau cov xov xwm corrosive thiab tseem pab lub hom phiaj zoo nkauj. Rau cov khoom lag luam tooj liab siv nyob sab hauv tsev lossis hauv cov tsev me thiab cov khoom siv hluav taws xob yog cov qauv hluav taws xob yog qhov yooj yim thiab zoo corrosion tiv thaiv txoj kev.
2. Kev sib dhos lossis microalloying
Ntxiv cov khoom siv alloy: ntxiv cov khoom siv tawm xws li tin, txhuas, thiab npib tooj liab tuaj yeem hloov nws cov microstructure thiab txhim kho nws corrosion tsis kam.
Piv txwv li, tin bronze, tsim los ntawm kev ntxiv tin rau tooj liab, cov khoom pov thawj zoo heev corrosion thiab siv tau dav hauv kev lag luam hauv nkoj thiab tshuaj lom neeg.
Aluminium tooj daj, tsim los ntawm kev ntxiv txhuas mus rau liab, muaj cov muaj zog ntau dua thiab corrosion tsis kam.
Microalloying, los ntawm kev ntxiv cov nyiaj ntawm cov khoom siv alloy xws li boron, zirconium, thiab kho lub pob tooj liab loj thiab txhim kho nws cov corrosion tsis kam. Cov kab lus no tsim cov teb ruaj khov ntawm lub cigpper cov qoob loo nplej, tiv thaiv kev sib cais ntawm cov corrosive media. Piv txwv li, cov kab laum ntawm cov neeg Boron tuaj yeem txhim kho tooj liab lub corrosion tsis kam nyob hauv seawater.
3. Kev tswj ib puag ncig
Txo cov av noo nyob hauv ib cheeb tsam uas cov khoom saib xyuas cov khoom lag luam uas cov khoom them nqi tooj liab tau khaws lossis siv tuaj yeem txo cov kev pheej hmoo ntawm corrosion. Dehumidification cov khoom siv thiab desiccants tuaj yeem siv los tswj cov av noo. Maintaining a low humidity environment is crucial for improving copper's corrosion resistance in humidity-sensitive environments, such as electronic equipment and precision instruments.
Zam kev sib cuag nrog corrosive media. Thaum tuav cov khoom lag luam tooj liab, txo kev sib cuag nrog cov xov xwm corrosive, xws li cov kua qaub, alkalis, thiab cov ntsev. Yog tias kev tiv thaiv tsis tuaj yeem zam, kev tiv thaiv kev tiv thaiv tuaj yeem coj, xws li siv cov ntaub ntawv ntim khoom lossis cov tsho loj. Piv txwv li, thaum thauj cov khoom tooj liab, siv zaj duab xis yas, ua npuas ncauj, lossis lwm yam ntim khoom ntim los tiv thaiv lawv ntawm kev sib chwv nrog kev sib tiv tauj.
4. Ua tib zoo
Ntxuav saum npoo. Nquag kho cov khoom dawb huv kom tshem tawm cov av, plua plav, thiab lwm yam tsis zoo los txo kev xeb. Siv cov tshuaj ntxuav mentsis thiab daim ntaub mos muag, zam kev huv huv.
Tsis tas li, tsis tu ncua tshuaj xyuas qhov chaw ntawm cov khoom lag luam tooj liab los kuaj pom thiab kho cov cheeb tsam corroded kom sai. Menyuam yaus plab corrosion tuaj yeem kho nrog cov suab paj nruag lossis polishing; Kev tiv thaiv loj heev yuav xav tau kev kho kom zoo lossis hloov. Piv txwv li, kev tshuaj xyuas thiab kho cov kav dej tooj liab siv tau cov cuab yeej siv tshuaj lom neeg tuaj yeem ua haujlwm kom muaj kev nyab xeeb ntawm cov khoom siv xws li tsis muaj txiaj ntsig los ntawm kev ua kom corrosion.
Lub tuam txhab muaj pawg ntawm cov coj tooj liab ua ntau lawm cov kab hauv Suav teb, suav nrog:
German tau yog precision tooj liab raj ntau lawm kab (ib xyoos tawm ntawm 30,000 tons)
Japanese technology Tooj liab ntawv tuav kab (thinnest txog li 6μm)
Tsis Siv Neeg Siab Tooj Liab Bar Nruam Extrusion Kab
Cov Ntawv Ntse Copper thiab Sawb Fining Mill Chav Tsev
Digitalized kev tswj hwm thiab kev tswj hwm ntawm tag nrho cov txheej txheem ntau lawm tau pom los ntawm cov khoom siv ntawm cov khoom lag luam, thiab qhov tseeb ntawm cov khoom tuaj yeem ncav cuag ± 0.01 hli.
