I-prepreg ephilisa ukukhanya ayisebenzi kakuhle nje kuphela xa isetyenziswa, kodwa ikwanokumelana nokugqwala kwii-asidi eziqhelekileyo, ii-alkali, iityuwa kunye nezinyibilikisi zendalo, kunye namandla oomatshini emva kokugqwala, njenge-FRP yendabuko. Ezi mpawu zibalaseleyo zenza ukuba ii-prepreg eziphilisa ukukhanya zilungele ii-chemical, iitanki zokugcina i-petroleum, iipayipi ezingaphezulu komhlaba kunye nezingaphantsi komhlaba, njl.njl., ukuvelisa izixhobo zokulwa nokugqwala ezisebenza kakuhle.
1. Ukusetyenziswa kwelayini yokulwa nokugqwala kwetanki yokugcina ioyile
Xa kuthelekiswa nenkqubo yokulungisa i-contact molding lining, kuba i-light-curing prepreg inokwenziwa ibe ngamashiti okanye imiqulu, kwaye kukho iifilimu zeplastiki kwiindawo eziphezulu nezisezantsi, i-solvent volatilization ngexesha lokwakha incinci, nto leyo ephucula kakhulu imeko yokwakha kunye nokhuseleko. I-prepreg engacinywanga ithambile kwaye inokunqunyulwa okanye inqunyulwe ngokweemfuno zeprojekthi ize isetyenziswe ngokuthe ngqo. Inyangwa ngokukhanya kwe-UV. Ixesha lokunyangwa liyimizuzu eli-10 ukuya kwengama-20 kuphela. Ayichaphazeleki kakhulu yimeko-bume kwaye ingasetyenziswa unyaka wonke. Ukwakhiwa, kunokusetyenziswa kwangoko emva kokunyangwa, kunciphisa kakhulu ixesha lokwakha kunye neendleko zomsebenzi.
Kwisikhululo sepetroli iPetroChina Chongming No. 3, i-light-cured prepreg elungiselelwe yi-MERICAN 9505 yasetyenziswa ukuhlaziya i-lining yetanki yokugcina ioyile. Iimeko ezifanelekileyo zokwakha ziboniswe kumfanekiso ongezantsi. Ubunzima bunokufikelela kuma-60, kwaye bunokumelana nokugqwala okuhle.
2. Ukusetyenziswa kokulwa nokugqwala kwimibhobho yokugrumba ebhekisa kwicala elithile
Ukubhola ngendlela eqondisayo yinkqubo yokwakha imibhobho kushishino lobuchwephesha bobunjineli. Isetyenziswa kakhulu ekwakhiweni kweoyile, igesi yendalo kunye neminye imibhobho kamasipala. Indlela yokukhusela isikhonkwane sangaphandle esichasene nokugqwala ngexesha lokubhola ngendlela eqondisayo yemibhobho ibisoloko iyingxaki enzima kwicandelo lokwakhiwa kwemibhobho. . Uninzi lwemibhobho eguquguqukayo isetyenziswa kwindawo yokuwela imibhobho ngendlela eqondisayo, kwaye ubunzima bomaleko ochasene nokugqwala kumphezulu womzimba wombhobho alwanelanga. Ngexesha lenkqubo yokutsala, umaleko ochasene nokugqwala uhlala uqhekekile okanye umphetho wezinto ezipeyintwayo ugobile okanye waphukile, nto leyo echaphazela isiphumo sokulwa nokugqwala kwaye ibeka emngciphekweni ukhuseleko lombhobho. Ngenxa yeengxaki ezingentla, i-prepreg ekhanyisiweyo ingasetyenziswa njengomaleko okhuselayo womaleko wangaphandle wombhobho. Iimpawu zayo eziphambili bubunzima obuphezulu, ukumelana nokukrwela kunye nokumelana nokungqubana, okunokukhusela kakuhle umaleko ochasene nokugqwala.
Uthelekiso lwesingxobo esikhuselayo esikhanyisa ukukhanya ngaphambi nasemva kokusetyenziswa kombhobho wokugrumba obhekisa kwicala luboniswe kumfanekiso olandelayo:
Kuyabonakala ngokucacileyo xa kuthelekiswa ukuba umaleko we-prepreg ophiliswe ngokukhanya unefuthe elihle lokukhusela umbhobho kwaye uphucula ukusebenza kombhobho okulwa nokugqwala.
3. Ukusetyenziswa kophahla lwetanki yokugcina ioyile negesi ngokuchasene nokugqwala
Uninzi lweetanki zokugcina ioyile negesi ziitanki zentsimbi zesinyithi. Ngenxa yokuba ioyile negesi zihlala ziqulathe izinto ezibolayo, ukubola kweetanki zesinyithi kuyingozi kakhulu. Umzekelo, phantsi kwesenzo sobushushu obuphezulu etankini, iigesi ezinobungozi ezifana neoksijini enyibilikisiweyo, ihydrogen sulfide kunye nekhabhoni diokside ziya kuguquka zibangele ukubola okunamandla phezulu kwetanki, okubangela umonakalo omkhulu phezulu kwetanki, okungabangela kuphela ukulahleka okukhulu kweoyile negesi, kodwa kwandisa ukhuseleko. Ukuze kusetyenziswe ngokukhuselekileyo iitanki zokugcina ioyile negesi, kufuneka ukugcinwa kwendawo okanye ukutshintshwa komphezulu wetanki rhoqo. Indlela yendabuko yokulungisa uphahla lwetanki kukutshintsha ipleyiti yentsimbi yophahla lwetanki yesinyithi, efuna ukuba itanki imiswe, icocwe, iyunithi yokwakha yenze amanyathelo okhuseleko, kwaye isebe lokhuseleko livume iileya ngokulandelelana. Ixesha lokwakha lide kwaye iindleko zokulungisa ziphezulu. Nangona kunjalo, kusetyenziswa i-prepreg yokukhanyisa ukukhanya, umphezulu wetanki okhoyo usetyenziswa njengetemplate, kwaye uyilwe kwaye usikwe kwindawo, kwaye ubotshelelwe nomphezulu wetanki yesinyithi yokuqala ukuze wenze yonke. Ngokusekelwe ekugcineni amandla etanki yokuqala, amandla omaleko odibeneyo ayaphindaphindwa kwaye angasetyenziswa njengesisombululo esitsha sokulungiswa kophahla lweetanki zokugcina ioyile negesi.
Ukongeza kwiintsimi ezichasene nokugqwala ezikhankanyiweyo apha ngasentla, iiprepreg eziphilisa ukukhanya zingasetyenziswa nakwiintsimi ezichasene nokugqwala ezifana neelinings zamachibi kwiindawo ezingaphantsi komhlaba, iipayipi ezingaphantsi komhlaba, iitanki zokugcina inkunkuma kwiindawo zokulahla inkunkuma, iidekhi zeenqanawa, kunye nokuhlaziywa kwezityalo zamandla. Okwangoku, uninzi lweeshiti zokulungisa ukukhanya ezikwimarike ziimveliso ezingeniswa kwamanye amazwe, kwaye iindleko ziphezulu, nto leyo ethintela ukusetyenziswa kwazo. Nangona kunjalo, ngenkxaso karhulumente, ingqalelo yemarike, kunye notyalo-mali olongezelelekileyo lwezixhobo zophando nophuhliso, kuya kubakho iintlobo ezahlukeneyo zamaphepha okulungisa ukukhanya asekhaya asetyenziswa kwiinkalo ezahlukeneyo.
