abstract
Cov txheej txheem tiv thaiv corrosion ntawm 3PE tiv thaiv corrosion steel yeeb nkab yog qhov tseem ceeb rau lub neej ntawm cov kav dej faus. Qee cov kav dej uas ua los ntawm cov khoom siv tib yam yuav tsis corrode tom qab faus rau hauv av tau ntau xyoo lawm, thaum lwm tus yuav tawm hauv ob peb xyoos. Qhov no yog vim tias lawv siv cov txheej txheem sib txawv los tiv thaiv corrosion. Tam sim no, cia peb tshawb xyuas cov qauv ntawm 3PE los tiv thaiv corrosion steel kav.
3PE anti-corrosion steel yeeb nkab yog hais txog peb txheej polyethylene txheej sab nraud los tiv thaiv corrosion steel yeeb nkab, uas feem ntau siv hauv Suav teb. Lwm txoj hauv kev los tiv thaiv corrosion xws li IPN8710, FBE epoxy hmoov, epoxy thee bitumen thiab lwm yam. Cov txheej txheem no universally xa mus rau kev tiv thaiv corrosion ntawm sab nrauv phab ntsa ntawm cov kav hlau.
3PE anti-corrosion steel yeeb nkab cov ntaub ntawv muaj xws li seamless steel kav, kauv steel kav thiab ncaj seam steel kav.
anti-corrosion qauv
Anti-corrosion Daim Ntawv ntawm Cov Phab Ntsa Sab Nraud ntawm Hlau Yeeb Nkab
"3PE" feem ntau muaj peb txheej:
The first layer is epoxy powder (FBE>100 hli);
Qhov thib ob txheej yog nplaum (AD) 170 ~ 250um;
Qhov thib peb txheej yog polyethylene (PE) 1.8 ~ 3.7mm.
Hauv kev ua haujlwm tiag tiag, peb cov ntaub ntawv sib xyaw thiab sib xyaw ua ke hauv ib qho. Tom qab ua tiav, lawv tau ruaj khov ua ke nrog cov yeeb nkab steel los tsim cov txheej txheem tiv thaiv corrosion zoo heev. Nws txoj kev ua haujlwm feem ntau muab faib ua ob hom: winding hom thiab puag ncig pwm npog hom.
3PE anti-corrosion steel yeeb nkab txheej, tseem hu ua peb-txheej polyethylene anti-corrosion txheej, yog ib tug tshiab anti-corrosion txheej uas ntse ua ke 2PE anti-corrosion txheej nyob rau hauv cov teb chaws Europe nrog ntau siv epoxy hmoov anti-corrosion steel yeeb nkab txheej. (FBE) hauv North America. Nws tau raug lees paub thiab siv thoob ntiaj teb rau ntau tshaj kaum xyoo.
Cov txheej txheem ntawm 3PE tiv thaiv corrosion steel yeeb nkab yog epoxy hmoov los tiv thaiv corrosion txheej uas nws cov txheej hauv qab yog nyob rau hauv kev sib cuag nrog rau saum npoo ntawm cov yeeb nkab steel, thiab nruab nrab txheej yog ib co-polymerized nplaum nrog branched structural functional pawg. Cov txheej txheej saum npoo yog high-density polyethylene anti-corrosion txheej.
3PE anti-corrosion txheej integrates lub siab impermeability thiab zoo heev mechanical zog ntawm epoxy resin thiab polyethylene cov ntaub ntawv. Txog tam sim no, nws tau lees paub thoob ntiaj teb tias yog qhov ua tau zoo tshaj plaws thiab ua tau zoo tshaj plaws ntawm cov kav dej los tiv thaiv corrosion txheej, thiab tau siv rau ntau qhov haujlwm.
Peb-txheej polyethylene (3PE) anti-corrosion txheej tau dav siv nyob rau hauv cov roj pipeline kev lag luam vim nws zoo corrosion kuj, dej vapor permeability kuj thiab superior mechanical zog.
anti-corrosion ntawm sab hauv phab ntsa ntawm cov yeeb nkab steel
Muaj ob hom kev tiv thaiv corrosion rau sab hauv phab ntsa ntawm cov kav hlau steel: ib qho yog kub-melt epoxy resin hmoov (siab kub sintering), thiab lwm yam yog kua epoxy txheej, cov uas IPN8710 (txias txau ntawm qhov kub thiab txias) yog ntau dua. nquag ua haujlwm.
Qhov sib txawv ntawm daim ntawv, txheej txheem thiab kev ua tau zoo ntawm ob hom ntawm cov phab ntsa sab hauv los tiv thaiv corrosion yog tshwj xeeb hauv cov hauv qab no:
