Cov kav hlau ib txwm muaj xws li cov kab hlau hlau feem ntau yog cov qauv sib txawv hauv qab no, thiab cov qauv sib txawv yog qhov tsim nyog rau kev sib txawv tiv thaiv corrosion thiab siv ib puag ncig:
Qhov tseem ceeb txheej txheem kev kho mob
1. Ntxuav
Kev siv cov kuab tshuaj los yog paug kom tshem tawm roj, plua plav thiab lwm cov organic teeb meem nyob rau saum npoo ntawm cov kav hlau, tab sis tsis tuaj yeem tshem cov xeb thiab oxidation, feem ntau yog kauj ruam ua ntej.
2. Tshem tawm xeb siv cov cuab yeej
Los ntawm kev sib tsoo ntawm cov nplaim nrog cov cuab yeej siv hluav taws xob xws li cov hlau txhuam thiab sib tsoo cov log, xoob xeb, xoob xoob thiab muab tshem tawm. Cov cuab yeej tshem tawm xeb ntawm cov cuab yeej ntawm tes ncav cuag SA2 qib kom ncav cuag SA3 qib, tab sis cov nyhuv rau cov neeg tawv nqaij oxidation muaj tsawg.
3. Pickling
Siv tshuaj lom neeg lossis cov qauv elecrocytic (cov siv hydrochloric acid, thiab lwm yam) kom yaj oxide thiab xeb, haum rau kev kho oxide tom qab sandblasting. Txawm li cas los xij, nws yuav ua rau cov kab ib puag ncig, thiab cov kab thauj tog rau nkoj yog ntiav.
4. Tsuag (pov) Dav hlau Rust tshem tawm
Los ntawm txau cov ntaub ntawv uas tsis muaj zog xws li steel xuab zeb thiab steel pellets los ntawm kev siv hluav taws xob siab, tus xeb yog tsim kom meej rau kev txhim kho cov nplaum ntawm txheej. Tua cov noog rau sab hauv phab ntsa thiab tua peening rau sab nraud phab ntsa yog qhov zoo rau Anticorrosive entricorrosering.
Txhim kho los tiv thaiv corrosion / kev kho mob ua haujlwm
1. Kub-DIP Galvanizing
Galvanized nyob rau saum npoo ntawm cov yeeb nkab steel los ua ib txheej tiv thaiv, tseem txhim kho corrosion tsis kam, tshwj xeeb yog tsim nyog rau sab nraum zoov lossis kev ua tub rog, lub neej muaj ntau caum xyoo.
2. Txau anti-corrosion txheej
Siv cov xim pleev xim, hmoov thiab lwm cov ntaub ntawv los npog saum npoo, ob qho tib si tiv thaiv corrosion thiab cov nyhuv zoo. Txau thev naus laus zis tseem txhim kho cov hnav tsis kam thiab haum rau cov chaw hnyav.
3. Phosphallating Kev Kho Mob
Kev ua yeeb yaj kiab phosphate yog tsim los txhim kho corrosion tsis kam thiab txheej nplaum, feem ntau siv los ua txheej txheej.
4. Plating
Electrochemical tso tawm ntawm cov kav hlau hlau (xws li npib tsib (chromium) los txhim kho corrosion tsis kam, hnav tsis kam thiab ua kom pom cov ntsej muag.
5. Kev kho mob passivation
Chromate lossis nitric acid passivation daws tau siv los ua nanoscale oxide zaj duab xis, thiab feem ntau tau siv nyob rau hauv cov khoom lag luam siab xws li seamless steel kav.
6. Anodic Oxidation (Electrochemical Oxidation)
Nws yog mas thov rau alloy steel kav los tsim cov yeeb yaj kiab dense kom txhim kho lub hardness, hnav tsis kam thiab corrosion tsis kam, thiab tuaj yeem kho cov xim nto.
Xaiv Kev Xaiv
• Kev tsim kho tiv thaiv kev tiv thaiv corrosion General: Txuaj (pov) Dav Hlau Luv + Txau Txheej.
• Muaj kev tiv thaiv muaj zog: Cov dej kub galvanizing lossis passivation kev kho + multilayer txheej.
• Hnav / kev ua kom zoo nkauj: electroplating lossis anodizing.
• Kev kho kom pipeline sab hauv phab ntsa: Qhov tseem ceeb ntawm kev txhaj tshuaj pe xeb lossis pickling passivation.
