| Sab hauv los tiv thaiv-corrosion nrog FBE epoxy hmoov | Sab hauv phab ntsa ntawm cov yeeb nkab yog kho nrog epoxy hmoov los ntawm electrostatic txau los yog thermal txau. Cov txheej yog du, txo cov dej tsis kam thiab tiv thaiv corrosion thiab scaling ntawm sab hauv phab ntsa |
|
| Cement mortar hauv ob sab phlu | Loj - txoj kab uas hla steel kav (feem ntau DN Ntau dua lossis sib npaug li 300) kab nrog cov cement mortar. Nws yog tus nqi - siv tau zoo thiab tuaj yeem tiv thaiv dej tsis zoo, tab sis nws tuaj yeem ua rau muaj kuab lom. |
|
| Hlau txheej tshuab | Kub-dip galvanizing |
Raus cov yeeb nkab steel hauv molten zinc ntawm kwv yees li 500 degree. Cov txheej yog tuab, muab kev tiv thaiv cathodic (sacrificial anode), nrog zoo durability, thiab yog dav siv nyob rau hauv ntau yam lag luam. |
| Kub galvanizing (electro{0}}galvanizing | Galvanization yog ua tiav los ntawm cov txheej txheem electrochemical. Cov txheej yog nyias nyias, thiab lub sij hawm tiv thaiv -corrosion yog luv dua li ntawm kub -dip galvanizing, tab sis tus nqi qis dua | |
| Lwm yam kev tiv thaiv | FRP casing method | Qhwv fiberglass reinforced yas cov ntaub ntawv nyob ib ncig ntawm cov yeeb nkab steel. Corrosion-resistant thiab hnav-resistant, nws yog haum rau tshwj xeeb corrosive ib puag ncig los yog kho cov kav dej qub |
| Ntawm - txoj kev txau ntawm qhov chaw | Epoxy resin, polyurethane thiab lwm yam txheej txheej yog txau rau ntawm cov kav dej steel ntawm qhov chaw tsim kho. Nws yog yoog raws hauv kev tsim kho thiab haum rau cov qauv steel ntawm ntau yam duab thiab ntau thiab tsawg. |
💡Yuav ua li cas xaiv txoj kev tiv thaiv -corrosion
Qhov kev xaiv ntawm txoj kev tiv thaiv-corrosion txoj kev siv nyob ntawm seb qhov kev thov tshwj xeeb thiab ib puag ncig ntawm cov yeeb nkab steel.
• Cov kav dej faus:
Rau faus cov kav dej ntawm cov roj, cov roj av, dej xa mus, thiab lwm yam, 3PE tiv thaiv - corrosion yog qhov kev xaiv zoo tshaj plaws ntawm kev ua tau zoo. Yog tias tus nqi raug coj mus rau hauv tus account, epoxy thee tar pitch kuj yog ib qho kev daws teeb meem, thiab kev tiv thaiv cathodic tuaj yeem txiav txim siab ntxiv raws li qhov corrosiveness ntawm cov av.
• Tsis yog- faus overhead pipelines:
Nws raug nquahu kom siv cov txheej txheem rau kev tiv thaiv sab nraud -corrosion. Cov txheej txheem xws li epoxy resin thiab ethylene xim tuaj yeem xaiv tau.
• Rau kev thauj mus los ntawm cov xov xwm rhiab heev xws li dej haus:
Sab hauv los tiv thaiv-corrosion yuav tsum siv tsis yog- cov coatings coatings, xws li IPN8710 los yog fusion-bonded epoxy hmoov (FBE), kom muaj kev nyab xeeb ntawm dej.
• Siab- qhov kub thiab txias:
Cov txheej tshwj xeeb xws li silicone siab -kub los tiv thaiv- corrosion tuaj yeem raug txiav txim siab, uas tuaj yeem tiv taus qhov kub txog li 600 degree.
• Sib npaug ntawm kev lag luam thiab kav ntev:
Rau loj - txoj kab uas hla cov kav dej, siv cov cement mortar hauv ob sab phlu sab hauv yog ib qho kev daws teeb meem zoo. Rau cov qauv sab nraum zoov uas yuav tsum muaj kev ua haujlwm siab, kub -dip galvanizing muab tus nqi zoo heev.
🔧 Kev tsim kho kom zoo yog qhov tseem ceeb
Tsis muaj teeb meem zoo npaum li cas cov khoom siv tiv thaiv corrosion raug xaiv, yog tias kev tsim kho tsis raug, cov nyhuv yuav raug txo kom tsawg.
• Kev kho deg:
Qhov no yog lub hauv paus ntawm kev tiv thaiv -corrosion engineering. Qhov saum npoo ntawm cov yeeb nkab steel yuav tsum tau ua kom nruj xeb thiab tshem tawm cov roj. Feem ntau, sandblasting xeb tshem tawm yuav tsum ncav cuag qib Sa2.5 tus qauv kom nthuav tawm cov xim hlau.
• Txheej thickness:
Nws yog ib qho tseem ceeb los xyuas kom meej tias cov tshuaj tiv thaiv -corrosion txheej nce mus txog qhov tsim cov tuab tuab (feem ntau tshaj 150μm) txhawm rau tsim kom muaj kev tiv thaiv zoo.
• Kev tswj ib puag ncig:
Thaum lub sij hawm tsim kho, nws yog ib qho tsim nyog los tswj qhov kub thiab av noo ntawm qhov chaw thiab tsis txhob ua haujlwm nyob rau hauv cua, xuab zeb, los nag, daus los yog condensation ib puag ncig.
• Lub sijhawm txheej txheem:
nruj me ntsis tswj lub sij hawm txheej txheej ntawm txhua lub tsho tiv no raws li cov khoom yuav tsum tau kom tsis txhob cuam tshuam cov adhesion ntawm cov khaubncaws sab nraud povtseg.
