, Cov ntsiab lus hauv qab ntawm Saltwet dej corrosion: Lub "Ob Qhov Kev Tawm Tsam" ntawm Chloride ions
Cov tshuaj corrosion los ntawm Saltwater tsis yog qhov yooj yim oxidation cov tshuaj tiv thaiv, tab sis tau ua tiav los ntawm cov nyhuv synetgistic ntawm kev puas tsuaj ntawm chloride rion thiab electrochemical corrosion
Kev Nkag Rau Lub Cev Lub Cev: Cho kaub kab mob muaj lub vojvoog me me thiab muaj peev xwm ncaj qha rau cov duab xim oxide (xws li tso tawm cov hlau sib dhos.
Electrochemical corrosion: nyob rau hauv ib puag ncig huab cua, chloride ions form microbataties nrog hlau. Anode cheeb tsam (hlau) yog oxidized rau fe ⁺ ⁺, thaum lub Cathygen cov tshuaj tiv thaiv oxygen, nrawm qhov kev xaus ntawm hlau ions. Cov ntaub ntawv sim qhia tau tias nyob rau hauv ib qho kev sim ntawm 3.5%
Rau lub Damascus riam, muaj peev xwm sib txawv ntawm cov txheej txheem carbon steel (nrog rau cov ntsiab lus carbon monoxide (nrog rau cov kab ke carbon monoxide)
2, cov ntsiab cai tseem ceeb ntawm kev tu cev hauv Saltwater ib puag ncig: Peb cov kev thaiv kev xeb
Cov tshuaj tiv thaiv corrosion yuav tsum muaj plaub yam kev ua ib txhij: Hlau substrate, electrolyte (ntsev), oxygen, thiab lub sijhawm. Yog li ntawd, tus tseem ceeb ntawm kev txij nkawm cov lus dag nyob rau hauv kev sib txuas hauv cov saw corrosion los ntawm kev rho tawm lub cev, tshuaj lom zem, thiab ua raws sijhawm)
Kev rho tawm ntawm lub cev: Tiv thaiv kev haus dej los ntawm kev tiv tauj cov hlau los ntawm kev pleev xim lossis qhuav ib puag ncig.
Tshuaj Hla: Siv cov xeb ua xeb (xws li sodium nitrite thiab phosphate) nyob rau hauv cov duab tiv thaiv ntawm cov hlau nto, inhibiting cov adsorption ntawm chloride ions.
Lub sij hawm tswj: shorten lub sijhawm sib cuag nrog cov dej qab ntsev kom tsis txhob muaj cov tshuaj corrosion.
3, Cov Txheej Txheem Tu Cai: Tas Nrho Cov Tsheb Sib Tw los ntawm kev siv ua ntej kom ntev- sij}
1. Ua ntej Kev Tiv Thaiv: Tsim txoj kev tiv thaiv peb npaug tiv thaiv
Kev siv saum npoo av: Ua ntej siv, maj mam zom cov hniav nrog 600 grit sandpaper kom tshem tawm cov txheej oxide thiab ua cov khoom seem, ua kom muaj kev nkag mus rau cov roj xeb.
Txheej Txheej Txheej Txheem Ntxhia (xws li tshuab xaws roj (xws li tshuab xaws roj) lossis riam tshuab tshwj xeeb los ua ib qho 0.1 {millimeter tuab cov tshuaj yeeb yaj kiab roj. Rau cov cuab yeej loj, ib qho kev sib xyaw ntawm beeswax thiab cov roj ntxhia sib xyaw ua ke hauv 1: 3 yuav siv tau, uas muaj qhov ntsuas kub siab dua li tib neeg lub cev thiab tuaj yeem ua raws li ntev.
Kev tswj hwm ib puag ncig: yog tias tsim nyog los ua haujlwm nyob rau hauv ib qho kev ua yeeb yaj kiab los yog nuv ntses), silica gel desiccant tuaj yeem tswj hwm cov av noo hauv tsawg dua lossis sib npaug 40%.
2. Hauv kev siv txij nkawm: kev tiv thaiv tu thiab kev tiv thaiv kev tiv thaiv kev tiv thaiv
Txoj kev kho tsis pub dhau 10 feeb tom qab kev sib cuag nrog Saltwater: yaug cov hniav nrog dej ntws kom tshem tawm cov tshuaj ntxuav cov roj (uas yuav ua rau cov roj ua yeeb yaj kiab).
So cov txheej txheem: Txais yuav "peb {- kauj ruam soft txoj kev":
Kauj ruam 1: Siv Ultra - Cov ntaub zoo fiber ntau los nqus cov npoo av;
Kauj ruam 2: Poob ib daim ntaub paj rwb hauv cov dej cawv me me thiab so los txhawb dej evaporation;
Kauj ruam 3: Thov ib txheej txheej nyias nyias ntawm Anti Rust Roj dua, tsom rau kev tiv thaiv thaj chaw uas yog nquag txiav ntug thiab kev sib tshuam ntawm cov khaubncaws sab nraud povtseg.
Kev nquag siv cov xwm txheej: Yog tias yuav tsum tau ua haujlwm roj av tau muab rov ua tau txhua 2 teev, lossis tshuaj txau hom kev kho tus neeg saib xyuas muaj cov corrosion inhibitor yuav siv tau.
3. Tom qab siv txij nkawm: kev tu kom sib sib zog nqus thiab ntev- sijhawm cia
Tu kom huv:
Disassemble qhov kov (yog tias tsis khov) thiab ntxuav cov ntsev hauv cov khoob nrog tus txhuam hniav;
Soak tus hniav hauv nruab nrab tu cov tshuaj (xws li dej sov + ib qho me me ntawm ci dej qab zib) rau 10 feeb los ua si muag tawv tawv;
Maj mam txhuam cov txheej txheej txheej txheej nrog cov mos mos bristled txhuam kom tsis txhob khawb qhov chaw.
Kho kom qhuav:
Tshuab qhuav hniav nrog cua compressed cua lossis muab tso rau hauv qhov cub qhuav (kub tsawg dua lossis sib npaug tsawg dua lossis sib npaug rau 1 teev;
Txwv tsis pub siv cov cua sov huab cua, ua rau cov roj kub tuaj yeem ua rau cov roj yeeb yaj kiab cov pa roj carbonancation thiab nrawm muaj xeb.
Lub Sij Hawm Ntev:
Thov ib txheej tuab ntawm anti xeb roj (xws li vaseline) nrog lub tuab ntawm li 0.5 millimeters;
Qhwv hauv cov ntaub ntawv roj lossis noo noo - ntawv pov thawj hnab thiab qhov chaw hauv lub thawv kaw;
Store in a cool and dry place to avoid temperature fluctuations (temperature difference>10 Qib Kawm Ntawv tuaj yeem ua rau hws).
4, Kho Ceev: Kho sai nyob rau hauv thaum ntxov ntawm corrosion
Yog tias muaj xeb me ntsis (xeb saib txoj kab uas hla<1 mm) occurs on the blade due to negligence, the following steps can be taken to handle it:
Kev tshem tawm lub cev: Siv 600 grit sandpaper rau maj mam polish Lub xeb kom txog thaum cov qauv stacking yog nthuav tawm, zam kev puas tsuaj rau cov qauv los ntawm kev sib txuas ua ke.
Tshuaj Hla: DIP ib cov paj rwb muab tso rau hauv ib qho me me ntawm cov phosphoric acid tov (kev siv 5%) thiab muab nws rau thaj chaw corroded. Tom qab 1 feeb ntawm cov tshuaj tiv thaiv, yaug nrog dej huv.
Kev tiv thaiv txhim kho: Re Thov Compioite Anti Quam Roj Muaj Nano Titanium Dioxide, uas nws cov physocatalytic yuav decompose seem ntawm chloride ions.
If the rust is severe (rust spot diameter>5 hli lossis interlayer tev), nws yuav tsum tau xa mus rau ib rhiav kev ua yeeb yam zoo nkauj:
Soak tus hniav hauv 10% hydrochloric acid daws rau 3-5 feeb kom yaj cov txheej xeb;
Tom qab nruab nrab ntawm cov kua qaub, txhuam nws nrog 8000 grit sandpaper kom ua tiav daim iav nyhuv;
Rov ua cov kua qaub los qhia cov qauv, thiab thaum kawg siv tshuaj tiv thaiv xeb.
5, kev txawj yuam kev misconceptions thiab kev paub tseeb
Kev ua txhaum: "Stainless hlau Damascus riam tsis xav tau kev kho mob"
Qhov tseeb: Txawm hais tias stainless hlau Damascus (xws li VG-10, S30V) muaj cov kua txiv ntau dua thiab yuav tsum muaj roj roj thiab tu.
Kev ua txhaum: "Tawv Sheaths tuaj yeem tiv thaiv ya kom noo"
Qhov Tseeb: Tawv muaj cov dej noo noo noo, thiab ntev -}} Text raug rau dej qab ntsev yuav ua rau muaj dej qab zib ua rau kev xeb ntawm cov hniav. Txoj kev kom yog yog khaws rab riam nyias nyias los ntawm cov txaj thiab tsis tu ncua siv cov neeg saib xyuas tawv nqaij tawv rau lub hnab.
Kev ua txhaum cai: "Roj cav lossis cov roj tau hloov tuaj yeem hloov cov roj tshwj xeeb roj"
Qhov tseeb: Cov roj tshuab muaj cov viscosity thiab muaj feem ntau rau cov plua tshauv adsorbing; Cov roj tau siv tau yog qhov ua rau muaj kev lwj, uas tau ua rau muaj kev xeb corrosion. Lub teeb ntxhia roj lossis cov roj muaj riam tshwj xeeb yuav tsum tau xaiv.
