Pipeline peb-txheej PE tiv thaiv corrosion yog cov thev naus laus zis tshiab hauv kev lag luam yeeb tshuaj tiv thaiv corrosion.Peb lub PE npog cov lus qhia Lou overlay zoo, nws cov khoom sib txuas, hluav taws xob rwb thaiv tsev, dej tsis kam thiab kev tiv thaiv corrosion thiab txhua yam muaj zog thiab toughness zoo heev.Cov txheej peb-txheej PE tiv thaiv corrosion tuaj yeem siv rau ntau qhov chaw ib puag ncig, ob qho tib si rau cov kav dej hauv av, tab sis kuj rau cov kav dej hiav txwv.
Lub raj xa dej peb PE tiv thaiv txheej txheej thiab cov khoom siv
Thawj txheej ntawm epoxy hmoov (FBE) 60 ~m;ob txheej ntawm cov nplaum (AD) 170 txog 250 m;txheej thib peb, polyethylene (PE) - 2.5 txog 3.0 mm.Peb cov ntaub ntawv fused rau hauv ib qho, thiab zoo heev los tiv thaiv corrosion txheej thiab txheej tiv thaiv yog tsim nrog steel yeeb nkab khov kho.Qhov thib peb txheej FBE siv, AD, PE yuav tsum tau hloov kho, sib txuam ua ke txhawm rau ua kom muaj cov nplaum zoo.Adhesive rau PE polymer, ntxiv ib qho nyiaj ntxiv, tshuaj lom neeg cov tshuaj tiv thaiv tshwm sim nyob rau hauv FBE gelled nrog ethylene, ruaj khov.Tsis tas li ntawd, vim tias cov nplaum nplaum thiab PE rau tib yam khoom siv hauv lub xeev molten, kev sib nrig sib fusion, tib yam ruaj khov.Peeling xeem yog cohesive tsis ua hauj lwm, piv txwv li cov yeeb nkab steel thiab txheej txheej tev tawm ob txheej dawb.
Kev sib piv ntawm peb-txheej PE tiv thaiv corrosion thiab anti-corrosion txheej
Petroleum asphalt, iav ntaub ntawm 60 ~ 7O cov khoom tseem ceeb ntawm cov kab mob tsis zoo thiab cov nroj tsuag sib sib zog nqus nkag mus rau qhov tsis zoo, tab sis vim nws lub neej luv luv, cov khoom siv kho tshuab, dej tsis kam, tiv thaiv corrosion tsis zoo, thiab kev tsim kho siv zog thiab nyuaj rau kev khiav lag luam. , thiab ua phem ib puag ncig.Coal tar enamel txawv teb chaws daim ntawv thov, tab sis vim nws cov neeg kho tshuab lub zog thiab tsis tshua muaj kub toughness, tshwj xeeb tshaj yog ib puag ncig muaj kuab paug tsim nyob rau hauv kev tsim kho ntawm flue roj uas muaj zog carcinogens, Australia thiab European lub teb chaws tau txwv tsis pub siv cov thee tar enamel.PVC txias daim kab xev qhwv nyob ib ncig ntawm peb lub teb chaws 70 mus rau 80 xyoo muaj ib tug me me daim ntawv thov, tab sis muaj ib tug tsis zoo daim ntawv cog lus kev ua tau zoo, lub domestic chamber nrog rau cov neeg kho tshuab lub zog thiab elongation ntawm tsis zoo thiab tus nqi siab, kev tsim kho machinery thiab cov khoom yuav tsum tau ntau dua unfavorable yam tseem ceeb tsho hauv chav kawm ntawv. npog txheej sau lub qhov ncauj nyuaj, yooj yim dej seepage thiab corrosion, pipeline kho teeb meem tshwm sim nyob rau hauv Los online daim ntawv thov, tsis tshua muaj siv.Epoxy hmoov coatings - ntau daim ntawv thov nyob rau hauv peb lub teb chaws, thiab nws muaj lub cev zoo thiab tshuaj muaj zog nrog steel nto adhesion thiab kub tsis kam, tab sis vim hais tias ntawm nws cov kev pab them nqi yog nyias thiab nkig, tsis zoo tiv thaiv rau sab nraud ib puag ncig thiab tsis tshua muaj siv nyob rau hauv ib leeg ntev- nyob deb ntawm cov kav dej.Pipeline Txheej PE tiv thaiv kov yeej qhov tsis zoo ntawm cov kab ke saum toj no-hais txog ntau yam tshuaj tua kab mob thiab muaj cov khoom zoo physicochemical, hluav taws xob insulating zog, waterproofing thiab tsis kam mus tshuaj tua kab mob, nrog rau zoo heev zog, tej yam kuj, thiab lwm yam, yog niaj hnub no npog txheej. nyob rau hauv lub zoo tagnrho preservative system.
