Umbhobho ongcwatywesebenza njengenye yezinto ezibalulekileyo zokuthutha i-oyile kunye negesi yokuhambisa igesi, ubunjineli bomhlaba, obudityaniswe ubutyebi obuphezulu kunye nabasebenzisi abasezantsi bekhonkco, ngenxa yombhobho omde wangcwatywa emhlabeni, ngokuhamba kwexesha, iimpawu zomhlaba wangaphandle kunye nokuhlaliswa kwe-topography. izinto, ukubola kwemibhobho, ukugqobhoza, ukuvuza, amasimi kunye namazwe anelahleko enkulu.Ngokwakhiwa, ilahleko yezoqoqosho ebangelwa kumbhobho we-oyile kunye ne-corrosion ye-gas pipeline inokwahlulwa ibe yilahleko ethe ngqo kunye nengathanga ngqo.Ilahleko ethe ngqo ibandakanya: ukutshintshwa kwezixhobo kunye neentlawulo zamacandelo, ukulungiswa kunye nomhlwa, njl.;ilahleko engangqalanga ibandakanya: ilahleko yemveliso, ukubola, ukuvuza okubangelwa yilahleko yemveliso, ukuqokelelana kweemveliso ezidlekayo okanye umonakalo obangelwe yilahleko, ilahleko engangqalanga kunelahleko ethe ngqo kwaye kunzima ukuyiqikelela.Ukonakala kwemibhobho ukongeza ekuqwalaseleni ilahleko emandla yezoqoqosho, kunokubangela ukuvuza kwezinto eziyingozi, kungcolise indalo, okanye kude kukhokhelele kwingozi yequbuliso kukhuseleko lomntu.Ukuthuthwa kwemibhobho yomgama omde wokuqokelelwa kwerhasi yendalo kunye nothungelwano lwemibhobho yothutho, umbhobho wobuchwephesha bokuthotywa kwangaphandle kunye nomgangatho wokwakha unxulumene ngokuthe ngqo nokusebenza okukhuselekileyo kunye nobomi benkonzo yombhobho.Indawo yokunqumla imibhobho enomhlaba ontsonkothileyo, iipropati zomhlaba ziyohluka kakhulu, umbhobho wentsimbi ongcwatyiweyo kufuneka uthabathe amanyathelo ahlukileyo omhlwa angaphandle.Iimpawu eziphambili zemibhobho yophuhliso lweteknoloji ye-corrosion yangaphandle ibonakaliswe kwi-high-performance anti-corrosion materials, i-composite, ubomi obude kunye noqoqosho oluhle.

Iimveliso zeteyiphu ezincamathelayo ezinomhlwa ikakhulu ziyi-polyethylene anticorrosion tape, i-polypropylene fibre corrosion tape, i-660 PE ye-anti-corrosion tape, iteyiphu yamalahle e-epoxy ebandayo, i-polyethylene anticorrosion tape kunye ne-polypropylene fiber corrosion tape ukuhlangabezana noluhlu olupheleleyo lobunjineli obunako ukuhlangabezana noluhlu olupheleleyo lobunjineli. .Inobambiso olomeleleyo kunye nokubambelela okuxhaswayo, ukuchasana kwempembelelo kunye nomdlalo olungileyo kunye nokhuseleko lwe-cathodic, eMntla Melika, eMzantsi Melika kunye neprojekthi ethile yasekhaya yombhobho.

I-Three-tier structure polyolefin (PE) iphuhliswe ngempumelelo eYurophu kwiminyaka yoo-1980 kwaye iqala ukuyisebenzisa i-FBE ilungile yokuchasana nomhlwa, i-adhesion, ukuxhathisa okuphezulu kwi-cathodic disbonding kunye nokunganyanzeki okuphezulu kwezinto ze-pololefin, indibaniselwano yokusebenza kweempawu ezilungileyo zoomatshini kunye nokuchasana Isakhiwo somhlwa woxinzelelo lomhlaba, ngokufika kwezicelo ezininzi zobunjineli, ngakumbi kumazwe aseYurophu, ukusetyenziswa kwayo bekuyindlela ekhulayo.Umaleko ongaphantsi we-PE epoxy coatings, umaleko ophakathi we-adhesive polymer, umaleko womphezulu we-polyolefin.I-adhesive inokuguqulwa i-polyolefin, equlethe iqela le-polar elifakwe kwi-polyolefin-carbon bond kwikhonkco eliphambili.Ke, i-adhesive ayinakho ukudibanisa i-polyolefin eguquliweyo, kodwa kunye nokusetyenziswa kweqela le-polar kunye ne-epoxy resin ephilisayo.Oku kudityaniswa kweempawu, ukufezekisa amandla okudibanisa awona aphezulu phakathi kokwaleka ezintathu, ngelixa iipropati kunye neempawu zeemaleko ezichaphazelekayo ukwenza umaleko wesithathu ube ngumphelelisi.Ibonakaliswa ngeendleko eziphezulu kunye nenkqubo enzima.
