Ob lub ntsiab lus, qhib zinc-nplua nuj epoxy primer rau lub sij hawm ntev tiv thaiv hlau nyob rau hauv ib puag ncig corrosive hnyav
Taw qhia
Ob lub ntsiab lus tiv thaiv corrosion epoxy zinc primer yog tsim los ntawm epoxy resin, zinc hmoov, hnyav, tus neeg sawv cev pabcuam thiab polyamide curing agent.
Nta
• Zoo heev anticorrosive zog
• Muab kev tiv thaiv cathodic rau cov cheeb tsam puas
• Cov khoom siv zoo heev
• Zoo heev adhesion rau moj tej tawg huv si carbon steel nto
• Zinc plua plav cov ntsiab lus 20%, 30%, 40%, 50%, 60%, 70%, 80% muaj
Pom zoo siv
Raws li ib tug primer rau blast-cleaned liab qab steel nto nyob rau hauv nruab nrab mus rau hnyav corrosive ib puag ncig, xws li steel qauv, txuas hniav, chaw nres nkoj machinery, offshore platforms, siv machinery, cia tso tsheb hlau luam thiab pipelines, hwj chim chaw, thiab lwm yam., ua ke nrog high-kev ua tau zoo. cov xim, uas tuaj yeem txhim kho kev tiv thaiv corrosion ntawm txheej txheej;
tuaj yeem siv rau ntawm kev pom zoo khaws cia zinc-nplua nuj khw primer nto;
Nws tuaj yeem siv los kho qhov chaw puas ntawm cov khoom siv galvanized lossis zinc silicate primer txheej;
Thaum lub sij hawm txij nkawm, nws tsuas tuaj yeem siv nws txoj kev tiv thaiv cathodic thiab tiv thaiv xeb ntawm qhov chaw kho rau liab qab steel.
Cov lus qhia siv
Muaj feem xyuam rau substrate thiab nto kho:moj tej tawg huv si rau Sa2.5 (ISO8501-1) los yog yam tsawg kawg nkaus SSPC SP-6, blasting profile Rz40μm ~ 75μm (ISO8503-1) los yog fais fab cuab yeej ntxuav kom tsawg kawg nkaus ISO-St3.0/SSPC SP3
Pre-coated rhiav primer:Welds, foob pob hluav taws calibration thiab puas yuav tsum tau blasting ntxuav rau Sa2.5 (ISO8501-1), los yog lub hwj chim cuab tam ntxuav rau St3, tsuas yog pom zoo tsis zoo zinc-nplua nuj rhiav primer yuav khaws cia.
Siv tau thiab kho
• Ambient ib puag ncig kub yuav tsum yog los ntawm rho tawm 5 ℃ mus rau 38 ℃, tus txheeb ze cov av noo yuav tsum tsis txhob ntau tshaj 85%.
• Substrate kub thaum lub sij hawm thov thiab kho yuav tsum yog 3 ℃ saum toj dew point.
• Kev thov sab nraum zoov yog txwv tsis pub muaj huab cua hnyav xws li los nag, pos huab, daus, cua daj cua dub thiab plua plav hnyav.
• Thaum Ambient ib puag ncig kub yog -5 ~ 5 ℃, tsis tshua muaj kub curing khoom yuav tsum tau siv los yog lwm yam kev ntsuas yuav tsum tau ua kom paub tseeb tias cov curing zoo ntawm cov xim zaj duab xis.
