I-prepreg yokwelapha ukukhanya ayigcini nje ngokusebenza kahle kokwakhiwa, kodwa futhi inokumelana okuhle nokugqwala kuma-asidi ajwayelekile, ama-alkali, usawoti kanye nezinyibilikisi eziphilayo, kanye namandla amahle okusebenza ngemva kokuqina, njenge-FRP yendabuko. Lezi zakhiwo ezinhle kakhulu zenza ama-prepreg aphulukiswayo alulame afanelekele amathangi amakhemikhali, okugcina uphethiloli, amapayipi angaphezulu komhlabathi nangaphansi komhlaba, njll., ukukhiqiza imishini yokulwa nokugqwala esebenza kahle kakhulu.
1. Ukusetshenziswa kolwelwesi olulwa nokugqwala lwethangi lokugcina uwoyela
Uma kuqhathaniswa nenqubo yokulungisa i-lining yokubumbana kokuxhumana, ngoba i-prepreg yokwelapha ukukhanya ingalungiswa ibe amashidi noma imiqulu, futhi kukhona amafilimu epulasitiki ezindaweni eziphezulu nezingezansi, ukuguquguquka kwe-solvent ngesikhathi sokwakha kuncane kakhulu, okuthuthukisa kakhulu indawo yokwakha kanye nokuphepha. I-prepreg yokwelapha ukukhanya engakaqedwa ithambile futhi inganqunywa noma inqunywe ngokwezidingo zephrojekthi bese isetshenziswa ngqo. Ilashwa ngokukhanya kwe-UV. Isikhathi sokwelapha singumzuzu ongu-10 kuya ku-20 kuphela. Ayithinteki kakhulu yindawo futhi ingasetshenziswa unyaka wonke. Ukwakhiwa, kungasetshenziswa ngokushesha ngemva kokwelashwa, kunciphisa kakhulu isikhathi sokwakha kanye nezindleko zomsebenzi.
Esiteshini sikaphethiloli iPetroChina Chongming No. 3, i-prepreg ekhanyiswe ukukhanya elungiselelwe yi-MERICAN 9505 yasetshenziswa ukuvuselela ulwelwesi lwethangi lokugcina uwoyela. Izimo zokwakha ezifanele ziboniswe esithombeni esingezansi. Ukuqina kwayo kungafinyelela ku-60, futhi inokumelana okuhle nokugqwala.
2. Ukusetshenziswa kokulwa nokugqwala epayipini lokubhoboza eliqondisa ohlangothini
Ukubhoboza ngokuqondisa kuyinqubo yokwakha ipayipi embonini yobuchwepheshe bobunjiniyela. Kusetshenziswa kabanzi ekwakhiweni kukawoyela, igesi yemvelo kanye neminye ipayipi kamasipala. Indlela yokuvikela igobolondo langaphandle elilwa nokugqwala ngesikhathi sokubhoboza ngokuqondisa ipayipi bekulokhu kuyinkinga enzima emkhakheni wokwakhiwa kwepayipi. . Iningi lamapayipi aguquguqukayo asetshenziswa ekuweleni kokubhoboza ngokuqondisa, futhi ubunzima besendlalelo sokulwa nokugqwala ebusweni bomzimba wepayipi akwanele. Ngesikhathi senqubo yokuhudula, isendlalelo sokulwa nokugqwala sivame ukuqhekeka noma unqenqema lwezinto zokunamathisela lugobile noma luphuke, okuthinta umphumela wokulwa nokugqwala futhi kubeke engcupheni ukuphepha kwepayipi engozini enkulu. Ngenxa yezinkinga ezingenhla, i-prepreg ekhanyiswe ukukhanya ingasetshenziswa njengesendlalelo esivikelayo sesendlalelo sangaphandle sepayipi. Izici zayo eziyinhloko ubulukhuni obuphezulu, ukumelana nokuklwebheka kanye nokumelana nokungqubuzana, okungavikela kahle isendlalelo sokulwa nokugqwala.
Ukuqhathaniswa kwesivikelo esivikela ukukhanya ngaphambi nangemva kokusetshenziswa kwepayipi lokubhoboza eliqondisa indlela kuboniswa esithombeni esilandelayo:
Kungabonakala ngokucacile ekuqhathaniseni ukuthi ungqimba lwe-prepreg olukhanyisiwe lunomphumela omuhle wokuvikela epayipini futhi luthuthukisa ukusebenza kokulwa nokugqwala kwepayipi.
3. Ukusetshenziswa kokulwa nokugqwala kophahla lwethangi lokugcina uwoyela negesi
Iningi lamatangi okugcina uwoyela negesi ngamatangi ensimbi ensimbi. Ngenxa yokuthi uwoyela negesi kuvame ukuqukatha izinto ezibolayo, ukugqwala kwamatangi ensimbi kukhulu kakhulu. Isibonelo, ngaphansi kwesenzo sokushisa okuphezulu ethangini, amagesi ayingozi njenge-oxygen encibilikisiwe, i-hydrogen sulfide kanye ne-carbon dioxide kuzoshintsha futhi kubangele ukugqwala okunamandla phezulu kwethangi, okubangela umonakalo omkhulu phezulu kwethangi, okungagcini nje ngokubangela ukulahlekelwa okukhulu uwoyela negesi, kodwa futhi kwandisa ukuphepha. Ukuze kusetshenziswe ngokuphephile amathangi okugcina uwoyela negesi, ukulungiswa kwendawo noma ukushintshwa kwephezulu lethangi kuyadingeka njalo. Indlela yendabuko yokulungisa uphahla lwethangi ukufaka esikhundleni sepuleti lensimbi lophahla lwethangi lensimbi, okudinga ukuthi ithangi limiswe, lihlanzwe, iyunithi yokwakha yakhe izinyathelo zokuphepha, kanye nomnyango wokuphepha ukuvumela izendlalelo ngezendlalelo. Isikhathi sokwakha side futhi izindleko zokulungisa ziphezulu. Kodwa-ke, kusetshenziswa i-prepreg yokukhanyisa ukukhanya, ingaphezulu lethangi elikhona lisetshenziswa njengethempulethi, futhi liklanywe futhi lisikwe endaweni, futhi lihlanganiswa nephezulu lethangi lensimbi lokuqala ukuze lakheke lonke. Ngokusekelwe ekulondolozeni amandla ethangi lokuqala, amandla engqimba ehlanganisiwe ayaphindaphindwa futhi angasetshenziswa njengesixazululo esisha sokulungisa uphahla lwamathangi okugcina uwoyela negesi.
Ngaphezu kwamasimu okulwa nokugqwala okukhulunywe ngakho ngenhla, ama-prepreg okukhanyisa angasetshenziswa nasezindaweni zokulwa nokugqwala njengezindawo zokubhukuda ezindaweni ezingaphansi komhlaba, amapayipi angaphansi komhlaba, amathangi okugcina izinto ezindaweni zokulahla udoti, amadekhi emikhumbi, kanye nokuvuselelwa kwezitshalo zamandla. Njengamanje, iningi lamashidi okukhanyisa alungisa ukukhanya emakethe ayimikhiqizo engenisiwe, futhi izindleko ziphezulu, okunciphisa ukusetshenziswa kwawo. Kodwa-ke, ngokusekelwa umbuso, ukunakwa kwemakethe, kanye nokutshalwa kwezimali okwandisiwe kwezinsiza zocwaningo nentuthuko, kuzoba nezinhlobo eziningi ezahlukene zamashidi okulungiselela ukukhanya asekhaya asetshenziswa emikhakheni ehlukene.
