3PE anticorrosive steel yeeb nkab los tiv thaiv-corrosion txheej txheem yog hais txog cov yeeb nkab steel uas tuaj yeem tiv thaiv kom tsis txhob muaj kev cuam tshuam ntawm cov tshuaj lom neeg lossis cov tshuaj electrochemical hauv cov txheej txheem ntawm kev thauj mus los thiab siv tom qab kev kho tshuab anticorrosive.
3PE -qib los tiv thaiv corrosion steel yeeb nkab yog peb txheej peb txheej polyolefin txheej (MAPEC) anticorrosive steel yeeb nkab feem ntau siv hauv kuv lub tebchaws. Thawj txheej ntawm epoxy hmoov (FBE yog ntau dua 100um), txheej thib ob ntawm cov nplaum (AD) yog 170 ~ 250m, thiab peb txheej ntawm polyethylene (PE) yog 2.5 ~ 3.7 hli. Lwm txoj hauv kev los tiv thaiv corrosion xws li IPN8710, FBE epoxy hmoov thiab ncej ncej.
Cov kev xav tau ntawm daim ntawv thov feem ntau suav nrog peb yam hauv qab no:
1. Cov txheej txheej tsim los ntawm cov txheej txheem zoo corrosion kuj yog ruaj khov thaum raug rau ntau yam corrosive media xws li acid, alkali, ntsev, dej phwj tuaj, tshuaj gases, thiab lwm yam, thiab yuav tsum tsis txhob yaj, bloated los yog decomposed los ntawm corrosive media. Cov tshuaj phem tshiab yuav tsum tsis txhob tsim nrog qhov nruab nrab;
2. Zoo los tiv thaiv-osmotic txheej tuaj yeem tiv thaiv nws txoj kev nkag mus thiab kho nws cov corrosion ntawm cov yeeb nkab nto thaum hu rau cov kua los yog roj nruab nrab uas muaj zog permeability;
3. Zoo adhesion thiab yooj, txheej yuav tsis poob vim kev co los yog me ntsis deformation ntawm cov kav dej, thiab cov txheej yuav tsum muaj qee yam kev siv zog.
Epoxy anticorrosive txheej muaj qhov zoo ntawm qhov muaj zog adhesion, acid thiab alkali tsis kam, thiab qis qis qis. Nws yog dav siv rau corrosion ntawm sab hauv thiab sab nrauv phab ntsa hauv cov kav dej. Qhov tsis zoo yog cov huab cua tsis zoo ntawm cov xim zaj duab xis thiab yooj yim tawg. Tshwj xeeb tshaj yog thaum kho kho tsis zoo, cov dej tsis kam ntawm cov txheej txheej tsis zoo, thiab nws yooj yim tig dawb thiab nkig.
