I-prepreg yokwelapha ukukhanya ayigcini nje ngokusebenza kahle ekwakhiweni, kodwa futhi inokumelana nokugqwala okuhle kuma-asidi avamile, ama-alkali, usawoti nezinyibilikisi eziphilayo, kanye namandla amahle okusebenza ngemva kokwelapha, njenge-FRP yendabuko.Lezi zakhiwo ezinhle kakhulu zenza ama-prepregs eselaphekayo ukukhanya afanelekele amakhemikhali, amathangi okugcina uphethiloli, amapayipi angaphezulu komhlaba nangaphansi komhlaba, njll., ukukhiqiza okokusebenza okulwa nokugqwala nokusebenza kahle kakhulu.
1. Ukufakwa kwe-anti-corrosion lining yethangi lokugcina uwoyela
Uma kuqhathaniswa nenqubo yokulungisa i-lining yokubumba yokuxhumana, ngoba i-prepreg yokwelapha ukukhanya ingenziwa ngaphambili ibe ngamashidi noma imiqulu, futhi kukhona amafilimu epulasitiki ezindaweni ezingaphezulu neziphansi, ukuvuthwa kwe-solvent ngesikhathi sokwakha kuncane, okuthuthukisa kakhulu ukwakhiwa. imvelo nokuphepha.ucansi.I-prepreg yokwelapha ukukhanya engelapheki ithambile futhi ingasikwa noma isikwe ngokwezidingo zephrojekthi bese isetshenziswa ngokuqondile.Yelapheka ngokukhanya kwe-UV.Isikhathi sokwelashwa siyimizuzu eyi-10 kuye kwengama-20 kuphela.Ayithinteki kangako imvelo futhi ingasetshenziswa unyaka wonke.Ukwakhiwa, kungasetshenziswa ngokushesha ngemva kokwelapha, ukunciphisa kakhulu isikhathi sokwakha kanye nezindleko zabasebenzi.
Esiteshini sikaphethiloli i-PetroChina Chongming No. 3, i-prepreg elashwe kancane elungiswe yi-MERICAN 9505 yasetshenziselwa ukuvuselela uhlaka lwethangi lokugcina uwoyela.Izimo ezifanele zokwakha ziboniswa esithombeni esingezansi.Ukuqina bungafinyelela ku-60, futhi kunokumelana nokugqwala okuhle.
2. Isicelo sokulwa nokugqwala epayipini lokumba eliqonde ngqo
Ukubhola ngokuqondisa kuyinqubo yokwakha ipayipi embonini yobuchwepheshe bonjiniyela.Isetshenziswa kakhulu ekwakhiweni kukawoyela, igesi yemvelo kanye namanye amapayipi kamasipala.Indlela yokuvikela i-anti-corrosion sheath yangaphandle ngesikhathi sokumba amapayipi okuqondisayo bekulokhu kuyinkinga enzima emkhakheni wokwakhiwa kwamapayipi..Iningi lamapayipi aguquguqukayo asetshenziselwa ukuwela ukuqondisa, futhi ukuqina kongqimba oluphikisana nokugqwala ebusweni bomzimba wepayipi akwanele.Ngesikhathi senqubo yokudonsa, ungqimba olunqanda ukugqwala luvamise ukuqhekeka noma unqenqema lwempahla yokuchibiyela iyasonteka noma iphukile, okuthinta umphumela wokunqanda ukugqwala futhi kubeke engcupheni ukuphepha kwepayipi.Uma kubhekwa izinkinga ezingenhla, i-prepreg eselashwe ngokukhanya ingasetshenziswa njengongqimba oluvikelayo lwengqimba yangaphandle yepayipi.Izici zayo eziyinhloko ubulukhuni obuphezulu, ukumelana nokuklwebheka nokumelana nokungqubuzana, okungavikela kahle ungqimba lwe-anti-corrosion.
Ukuqhathaniswa komkhono wokuvikela ukukhanya ngaphambi nangemva kokusetshenziswa kwepayipi lokumba eliqondisayo kukhonjiswe esithombeni esilandelayo:
Kungabonakala ngokucacile kusukela ekuqhathaniseni ukuthi ungqimba olulashwe ngokukhanyayo lunomphumela omuhle wokuvikela epayipini futhi luthuthukisa ukusebenza kokunqanda ukugqwala kwepayipi.
3. Ukufakwa kwe-anti-corrosion kophahla lwethangi lokugcina uwoyela negesi
Iningi lamathangi okugcina uwoyela negesi amathangi ensimbi.Ngenxa yokuthi uwoyela negesi kuvame ukuqukatha izinto ezonakalisayo, ukugqwala kwamathangi ensimbi kubi kakhulu.Isibonelo, ngaphansi kwesenzo sokushisa okuphezulu ethangini, amagesi ayingozi njenge-oxygen encibilikisiwe, i-hydrogen sulfide ne-carbon dioxide azoshintshashintsha futhi abangele ukugqwala okunamandla phezulu kwethangi, kubangele umonakalo omkhulu phezulu kwethangi, okuyinto akubangeli nje ukulahlekelwa okukhulu kwamafutha negesi, kodwa futhi kwandisa ukuphepha.ingozi efihliwe.Ukuze kusetshenziswe ngokuphephile amathangi okugcina uwoyela negesi, ukunakekelwa kwendawo noma ukushintshwa kwesiqongo sethangi kuyadingeka njalo.Indlela evamile yokulungisa uphahla lwethangi iwukumiselela ipuleti lensimbi lophahla lwethangi, okudinga ukuthi ithangi limiswe, lihlanzwe, iyunithi yokwakha ukuze yenze izinyathelo zokuphepha, futhi umnyango wezokuphepha ugunyaze izendlalelo ngongqimba.Isikhathi sokwakha side futhi izindleko zokulungisa ziphezulu.Kodwa-ke, kusetshenziswa i-prepreg yokwelapha ukukhanya, indawo engaphezulu yethangi ekhona isetshenziswa njengesifanekiso, futhi iklanywe futhi isikwe endaweni, futhi ihlanganiswe nephezulu yethangi lensimbi ukuze yakhe yonke.Ngesisekelo sokugcina amandla aphezulu e-tank yokuqala, Amandla ongqimba oluhlanganisiwe aphindaphindwa futhi angasetshenziswa njengesixazululo esisha sokulungisa uphahla lwamathangi okugcina amafutha negesi.
Ngaphezu kwalezi zindawo ezibalwe ngenhla zokunqanda ukugqwala, ama-prepreg okwelapha ukukhanya angasetshenziswa nasezindaweni zokunqanda ukugqwala ezifana ne-pool linings ezindaweni ezingaphansi komhlaba, amapayipi angaphansi komhlaba, amathangi okugcina ezindaweni zokulahla udoti, amadekhi emikhumbi, kanye nokulungiswa kwemishini kagesi.Njengamanje, amashidi amaningi okwelapha ukukhanya emakethe ayimikhiqizo engenisiwe, futhi izindleko ziphezulu, ezikhawulela ukusetshenziswa kwazo.Kodwa-ke, ngokwesekwa nguhulumeni, ukunaka kwemakethe, kanye nokutshalwa kwezimali okwandisiwe kwezinsiza zocwaningo nentuthuko, kuzoba nezinhlobo eziningi ezihlukene zamashidi asekhaya alashwe ngokukhanya asetshenziswa emikhakheni ehlukene.
