1. Yuav ua li cas rau kev txhim kho txheej txhim kho?
Zinc-Aluminium (ZN-AL) Alloy Txheej Txhim Kho
Lub hauv paus ntsiab lus: ntxiv 5% ~ 10% Aluminium mus rau qhov kub-dip galvanizing daws teeb meem al₂oy oxide zaj duab xis ntawm kev nkag mus ntawm corrosive media {}}
Cov nyhuv: cov corrosion tsis kam yog 2 ~ 3 zaug siab dua li ntawm lub neej kub - thiab lub neej muaj txiaj ntsig zoo nkauj galvanizing yog li 10 ~ 15 xyoos) {7} {{}
Qhov zoo ntawm ntau cov txheej txheej: corrosion ua ntawm zn-ni txheej (tsibcel cov ntsiab lus 8%, uas yog tsim rau cov roj wastewaterines nrog pH<4.
ZN-MG Txheej Txheej Kev Insoluble Mg (Oh) ₂ Cov Txheej Txheem Tshaj Plaws hauv Croside ion Ib puag ncig cog rau hauv Coastal zog cog pipelines.
2. Yuav ua li cas muab kev tiv thaiv kab ke rau saum npoo?
Kub-Dip Galvanizing + Epoxy Resin Txheej (EP)
Txheej Txheem: Tshuaj tsuag kua Epoxy cob, thiab tom qab kho cov txheej txheem 300 ~)
Hot-DIP Galvanizing + Polytetrafluoroethylene (PTFE) Txau
Nta: PTFE Txheej yog qhov kub-resistant - 200}} (assefaulis (suav nrog AQUACHOR
Kub-Dip Galvanizing + Zinc-Raws Li Zinc-nplua nuj Txheej
Lub hauv paus ntsiab lus: cov txheej muaj ntau dua 90% zinc hmoov, uas ua rau ib qho "kev tiv thaiv kab mob malvanized, thiab cov kev kho puas tuaj yeem kho tus kheej.
3. Yuav ua li cas thiaj ua tau zoo tsim qauv?
Nce cov txheej txheej txheej tuab thiab txheej av tuab
Plaster Thickness Qauv:
Ib puag ncig dav dav: ntau dua los yog sib npaug rau 55μm (ISO 1461);
Muaj ib puag ncig corrosive: Customized ntau dua los yog sib npaug rau cov marine engineering), txawm tias 100 ~ 120μm (Tshuaj High-Ntsev Wastewater) {4}
Txawj tej yam ntxiv cov phab ntsa tuab: Siv Sch80 lossis SCH160 qib ball-walled phab ntsa thickness tau nce los ntawm 4}}}
Streamined tsim tawm kev yaig corrosion
Kev Ntsuas: Siv lub vojvoog ntev ntev (r =1.5 d) kom txo cov raj hluav taws xob (xws li haum rau cov me me, dej phwj (dej phwj) {2}
4.} Ib puag ncig colosion tswj nruab nrab yog li cas?
Ntxiv rau Corrosion Inhibitors rau inhibit electrochemical corrosion
Hom:
Anodic corrosion inhibitors (xws li chromates, molybdates): tsim zaj duab xis passivation ntawm zinc nto;
Cathode corrosion inhibitors (xws li organic amines, thiadeas): Tiv thaiv hydrogen ions los ntawm catharging ntawm cathergging ntawm catheroen .
Daim Ntawv Thov: Ntxiv 0 {{{5% ~ 0.5% Sodium Raclosion Rau Lub Hot-Dip Galvanized Elbows Los Ntawm 0.2Mm / Xyoo Mus Rau Hauv 0.05mm / Xyoo.
Tswj nruab nrab kub thiab PH nqi
Qhov kub thiab txias: Tswj qhov nruab nrab kub hauv qab 60℃(tus corrosion tus nqi ntawm dej hiav txwv ntawm Seasater ntawm Seas {4 4} 8 degree).
PH tus nqi: Ntxiv rau neutralerizer (xws li sodium hydroxide) rau cov txheej txheem acidic (pH
{{0 {}} Yuav ua li cas ua kev saib xyuas ib txwm thiab saib xyuas?
Kev soj ntsuam tuab tuab thiab zinc ntxiv, kev tiv thaiv cathodic (CP) kev pab cuam system, corrosion thaum hais lus ceeb toom ntxov
