Pipeline atatu-wosanjikiza PE odana ndi dzimbiri ndi luso latsopano mu payipi anticorrosion makampani.Ma PE atatu omwe amaphimba zabwino zonse za Lou, mawonekedwe ake omangirira, mphamvu zotchinjiriza zamagetsi, kukana madzi ndi ntchito yodana ndi dzimbiri komanso mphamvu zamakina ndi kulimba kwake ndizabwino kwambiri.Zosanjikiza zitatu za PE anti-corrosion layer zitha kugwiritsidwa ntchito m'malo osiyanasiyana achilengedwe, popanga mapaipi okhazikika pamtunda, komanso mapaipi apanyanja.

Mapaipi atatu a PE odana ndi dzimbiri mawonekedwe ndi zida
Gawo loyamba la ufa wa epoxy (FBE) 60 ~m;gawo lachiwiri la zomatira (AD) 170 mpaka 250 m;wosanjikiza wachitatu, polyethylene (PE) - 2.5 mpaka 3.0 mm.Zida zitatuzo zimaphatikizidwa kukhala chimodzi, ndipo wosanjikiza bwino kwambiri wotsutsa dzimbiri ndi wosanjikiza woteteza amapangidwa ndi chitoliro chachitsulo mwamphamvu.Wachitatu wosanjikiza FBE ntchito, AD, Pe ayenera zosinthika mayeso, mafananidwe wina ndi mzake kuti kuonetsetsa katundu zomatira zabwino.Zomatira kwa PE polima, kuwonjezera kuchuluka kwa zina, mankhwala zimachitika mu FBE gelled ndi ethylene, olimba kugwirizana.Komanso, chifukwa zomatira ndi PE kwa mtundu womwewo wa zinthu mu wosungunuka boma maphatikizidwe, chimodzimodzi olimba kugwirizana.Peeling mayeso anali cohesive kulephera, mwachitsanzo zitsulo chitoliro ndi chophimba wosanjikiza peeled onse wosanjikiza woyera.

Kuyerekeza kwa magwiridwe antchito a magawo atatu osanjikiza a PE odana ndi dzimbiri ndi osanjikiza odana ndi dzimbiri
Mafuta a asphalt, nsalu zamagalasi za 60 ~ 7O's zazikuluzikulu zomwe zimatha kuwonongedwa ndi mabakiteriya ndi zomera zozama kwambiri zimadutsa zofooka, koma chifukwa cha moyo wake waufupi, mphamvu zamakina, kukana madzi, anti-corrosion sizigwira ntchito, komanso ntchito yomangamanga ndi yovuta kugwira ntchito. , ndi kuwononga kwambiri chilengedwe.Malasha phula enamel kunja ntchito, koma chifukwa mawotchi mphamvu ndi otsika kutentha toughness, makamaka kwambiri kuipitsa chilengedwe kwaiye pomanga chitoliro mpweya munali carcinogens amphamvu, Australia ndi mayiko a ku Ulaya momveka amaletsa ntchito malasha phula enamel.PVC ozizira tepi atakulungidwa m'dziko lathu 70 kwa zaka 80 anali ndi ntchito yaing'ono, koma ali osauka chomangira ntchito, chipinda m'nyumba ndi mphamvu makina ndi elongation wa khalidwe osauka ndi mtengo wapamwamba, makina yomanga ndi zipangizo zofunika apamwamba zinthu zoipa jekete kalasi. kuphimba wosanjikiza kudzaza pakamwa zovuta, mosavuta madzi seepage ndi dzimbiri, zochitika kukonza mapaipi zinachitika mu Los Intaneti ntchito, wakhala kawirikawiri ntchito.Epoxy ufa zokutira - ntchito zambiri m'dziko lathu, ndipo ali ndi makhalidwe abwino thupi ndi mankhwala ndi zitsulo pamwamba adhesion ndi kutentha kukana, koma chifukwa cha Kuphunzira ake ndi woonda ndi Chimaona, osauka kukana chilengedwe kunja ndipo kawirikawiri ntchito yekha yaitali- mtunda wapaipi.Pipeline Layer PE anti kugonjetsa kuipa kwa dongosolo la antiseptic zosiyanasiyana zomwe tatchulazi ndikukhala ndi zinthu zabwino za physicochemical, zotchingira magetsi zamagetsi, kutsekereza madzi komanso kukana kuukira kwamankhwala, komanso mphamvu zabwino kwambiri, kukana, ndi zina zambiri. mu njira yabwino kwambiri yosungira.
