Tus qauv kev ua haujlwm hauv tsev rau 3PE anticorrosive steel kav yog SY/T0413-2002, uas tau ua tiav thaum Lub Yim Hli 1, 2002. Cov qauv no feem ntau tswj kev siv cov polyethylene thiab high-density polyethylene, nrog rau Vicat softening point teem ntawm tsis muaj tsawg dua 110 degree. Lub thickness ntawm sab nraud anticorrosive txheej yog txiav txim siab raws li German tus qauv DIN30670-1991, uas tsom rau qis- thiab nruab nrab-density polyethylene, ua kom muaj kev cuam tshuam lub zog ntawm 3PE anticorrosive txheej. SY/T0413-2002 ho nce lub tev lub zog thiab qhov cuam tshuam qhov taw qhia ntawm 3PE anticorrosive txheej, thiab qhia meej meej cov pa roj carbon dub cov ntsiab lus ntawm qee cov ntaub ntawv tshwj xeeb, ua kom lub zog txhua yam thiab huab cua tsis kam ntawm 3PE anticorrosive txheej. Tsis tas li ntawd, nws nce qhov zaus ntawm qhov chaw kuaj xyuas qhov tev lub zog ntawm cov txheej txheem sib koom ua ke (piv txwv li, lub tev lub zog ntawm lub tes tsho ntawm lub tshav kub shrinkable thiab daim kab xev rau primer-coated steel).
Anticorrosive Structure rau Hlau Yeeb Nkab Sab nrauv phab ntsa
3PE anticorrosion system feem ntau muaj peb txheej:
1st Txheej: Epoxy hmoov (FBE> 100um)
Txheej 2: Adhesive (AD) 170 ~ 250um
Txheej 3: Polyethylene (PE) 1.8 ~ 3.7mm
Hauv kev ua haujlwm, peb cov ntaub ntawv no tau muab sib xyaw thiab sib xyaw ua ke, ua tiav los tsim kev sib raug zoo nrog cov yeeb nkab steel, tsim kom muaj cov txheej txheem tiv thaiv zoo heev. Cov txheej txheem ua feem ntau muaj xws li winding thiab ncig tuag txheej.
3PE anticorrosive txheej rau steel kav, tseem hu ua peb-txheej polyethylene anticorrosive txheej, yog ib hom tshiab txheej uas ingeniously sib txuas 2PE anticorrosive txheej los ntawm cov teb chaws Europe nrog rau cov dav siv epoxy hmoov anticorrosive txheej (FBE) rau steel kav nyob rau hauv North. Asmeskas. Cov txheej no tau lees paub thiab siv thoob ntiaj teb rau ntau tshaj kaum xyoo.
Cov txheej txheem ntawm 3PE anticorrosive steel kav muaj ib qho epoxy hmoov anticorrosive txheej nyob rau hauv kev sib cuag nrog cov yeeb nkab steel nto raws li hauv qab txheej, copolymer nplaum nrog cov pab pawg neeg ua haujlwm thiab cov qauv branched raws li nruab nrab txheej, thiab ib tug high-density polyethylene anticorrosive txheej raws li txheej saum toj kawg nkaus.
3PE anticorrosive txheej integrates lub siab impermeability thiab zoo heev txhua yam khoom ntawm epoxy resin thiab polyethylene cov ntaub ntawv. Nws tau lees paub thoob ntiaj teb tias ua tau zoo tshaj plaws thiab ua haujlwm siab tiv thaiv txheej rau cov kav dej, yog li siv dav hauv ntau qhov haujlwm engineering.
