Cov txheej txheem tiv thaiv corrosion ntawm 3PE anti-corrosion steel yeeb nkab yog hais txog kev kho cov kav hlau steel nrog cov cuab yeej tiv thaiv corrosion uas tuaj yeem tiv thaiv kom tsis txhob muaj kev cuam tshuam los ntawm cov tshuaj lom neeg lossis cov tshuaj electrochemical thaum thauj thiab siv.
3PE anti-corrosion steel yeeb nkab yog feem ntau siv peb-txheej polyolefin txheej (MAPEC) anti-corrosion steel yeeb nkab hauv Suav teb. Nws muaj peb txheej: thawj txheej yog epoxy hmoov (FBE, ntau dua 100um), txheej thib ob yog cov nplaum (AD) nrog lub thickness ntawm 170250μm, thiab txheej thib peb yog polyethylene (PE) nrog lub thickness ntawm 2.53.7mm . Lwm txoj kev los tiv thaiv corrosion xws li IPN8710, FBE epoxy hmoov, thiab epoxy thee tar suab.
Cov kev cai painting feem ntau suav nrog peb yam hauv qab no:
Kev Tiv Thaiv Zoo Tshaj Plaws: Cov txheej txheej tsim los ntawm cov xim pleev xim tiv thaiv yuav tsum nyob ruaj khov thaum raug rau ntau yam corrosive media xws li acids, alkalis, ntsev, dej phwj tuaj, thiab tshuaj lom neeg gases. Nws yuav tsum tsis txhob yaj, o, lossis decomposed los ntawm cov xov xwm no, thiab nws yuav tsum tsis txhob cuam tshuam nrog lawv los tsim cov tshuaj phem tshiab.
Zoo impermeability: Cov txheej yuav tsum zoo tiv thaiv kev nkag mus thiab kho corrosion ntawm cov yeeb nkab nto thaum nyob rau hauv kev sib cuag nrog cov kua permeable heev permeable los yog gas media.
Zoo heev Adhesion thiab Flexibility: Cov txheej yuav tsum tsis txhob detach vim cov yeeb nkab vibrations los yog me ntsis deformations. Nws yuav tsum muaj ib tug tej yam degree ntawm mechanical zog.
Epoxy anti-corrosion txheej yog dav siv rau kev tiv thaiv corrosion ntawm ob sab hauv thiab sab nrauv phab ntsa ntawm cov kav dej vim lawv cov adhesion muaj zog, tsis kam mus rau acids thiab alkalis, thiab tsawg shrinkage tus nqi. Txawm li cas los xij, lawv muaj qhov tsis zoo xws li huab cua tsis zoo, uas tuaj yeem ua rau tawg yooj yim, tshwj xeeb tshaj yog thaum cov txheej txheem kho tsis zoo. Nyob rau hauv tas li ntawd, cov txheej txheem dej tsis kam txo, ua rau nws yooj yim rau whitening thiab brittleness.
