I-prepreg yokunyanga ukukhanya ayinakusebenza kakuhle nje kolwakhiwo, kodwa ikwanokumelana ne-corrosion elungileyo kwi-asidi ngokubanzi, iialkali, iityuwa kunye nezinyibilikisi zezinto eziphilayo, kunye namandla omatshini alungileyo emva kokunyanga, njenge-FRP yemveli. Ezi zakhiwo zibalaseleyo zenza i-prepregs enyangekayo ekukhanyeni ilungele imichiza, iitanki zokugcina i-petroleum, ngaphezulu komhlaba kunye nemibhobho engaphantsi komhlaba, njl., Ukuvelisa izixhobo ezichasene nokuhlwa kunye nokusebenza okugqwesileyo.
1. Ukufakwa kwe-anti-corrosion lining yetanki yokugcina i-oyile
Xa kuthelekiswa nenkqubo yokulungiswa koqhagamshelwano lokubumba i-lining, kuba i-prepreg yokunyanga ukukhanya inokuthi ifakwe kwi-sheets okanye ii-rolls, kwaye kukho iifilimu zeplastiki kwiindawo eziphezulu kunye nezantsi, i-volatilization ye-solvent ngexesha lokwakha incinci, ephucula kakhulu indawo yokwakha kunye nokhuseleko. ngesondo. I-prepreg enganyangekiyo yokunyanga ukukhanya ithambile kwaye inokusikwa okanye isikwe ngokweemfuno zeprojekthi emva koko isetyenziswe ngokuthe ngqo. Inyangwa sisibane seUV. Ixesha lokunyanga li-10 kuphela kwimizuzu engama-20. Ayichatshazelwa kangako yimekobume kwaye ingasetyenziswa unyaka wonke. Ukwakhiwa, kunokusetyenziswa ngokukhawuleza emva kokunyanga, ukunciphisa kakhulu ixesha lokwakha kunye neendleko zabasebenzi.
Kwisikhululo segesi sePetroChina Chongming No. 3, i-prepreg elungiswe ukukhanya elungiswe yi-MERICAN 9505 isetyenziselwe ukuhlaziya umbane wetanki yokugcina i-oyile. Iimeko ezifanelekileyo zokwakha ziboniswe kumzobo ongezantsi. Ubunzima bunokufikelela kwi-60, kwaye inokumelana nokugqwala okuhle.
2. Ukusetyenziswa kwe-Anti-corrosion kwi-direct drilling pipeline
I-Directional Dlling yinkqubo yokwakhiwa kwemibhobho kwishishini lobuchwephesha bobunjineli. Isetyenziswa kakhulu ekwakhiweni kweoyile, igesi yendalo kunye neminye imibhobho kamasipala. Indlela yokukhusela i-sheath yangaphandle ye-anti-corrosion ngexesha lokugaya umbhobho we-directional isoloko iyingxaki enzima kwintsimi yokwakhiwa kwemibhobho. . Uninzi lwemibhobho eguquguqukayo isetyenziselwa ukuwela i-directional drilling crossing, kwaye ubunzima be-anti-corrosion layer ebusweni bomzimba wombhobho akwanelanga. Ngethuba lenkqubo yokutsala, i-anti-corrosion layer idla ngokuqhekeka okanye umgca wezinto ezibambekayo zihlanjululwe okanye zaphukile, ezichaphazela umphumo wokuchasana nokubola kwaye zibeke engozini kakhulu ukhuseleko lombhobho. Ngokujonga ezi ngxaki zingentla, i-prepreg enyangelwe ukukhanya ingasetyenziswa njengomaleko okhuselayo womaleko ongaphandle wombhobho. Iimpawu zayo eziphambili bubunzima obuphezulu, ukuxhathisa ukukrazula kunye nokumelana nokukhuhlana, okunokukhusela kakuhle umaleko ochasene ne-corrosion.
Ukuthelekiswa komkhono okhuselayo wokukhusela ukukhanya ngaphambi nangemva kokusetyenziswa kombhobho wokubhobhoza okhokelayo uboniswe kulo mfanekiso ulandelayo:
Inokubonwa ngokucacileyo ngokuthelekisa ukuba umaleko we-prepreg onyangelwe ngokukhanya unesiphumo esihle sokukhusela kumbhobho kwaye uphucula ukusebenza kombhobho wokuchasana nomhlwa.
3. Ukusetyenziswa kwe-anti-corrosion ye-oyile kunye nophahla lwetanki yokugcina igesi
Uninzi lwamatanki okugcina ioli kunye negesi ngamatanki esinyithi. Ngenxa yokuba ioli negesi zidla ngokuba nezinto ezidlayo, ukubola kwamatanki esinyithi kubi kakhulu. Umzekelo, phantsi kwesenzo sobushushu obuphezulu kwitanki, iigesi eziyingozi ezifana neoksijini enyibilikisiweyo, ihydrogen sulfide kunye nekharbon diokside ziya kuguquguquka kwaye zibangele umhlwa owomeleleyo kumphezulu wetanki, obangela umonakalo omkhulu kumphezulu wetanki, ongabangeli nje ilahleko enkulu yeoli kunye negesi, kodwa ikwanyusa ukhuseleko. ingozi efihliweyo. Ukusetyenziswa ngokukhuselekileyo kwe-oyile kunye ne-gas yokugcina i-tank, ukulungiswa kwendawo okanye ukutshintshwa kwe-tank top kuyadingeka rhoqo. Indlela yemveli yokulungisa uphahla lwetanki kukutshintsha ipleyiti yentsimbi yophahla lwetanki, efuna ukuba itanki imiswe, icocwe, iyunithi yokwakha ukwenza amanyathelo okhuseleko, kunye nesebe lokhuseleko ukuba livume iileya ngokwemaleko. Ixesha lokwakha lide kwaye iindleko zokulungisa ziphezulu. Nangona kunjalo, usebenzisa i-prepreg yokunyanga ukukhanya, umphezulu wetanki okhoyo usetyenziswa njenge template, kwaye uyilwe kwaye unqunyulwe kwindawo, kwaye udityaniswe nomphezulu wetanki yentsimbi ukuze wenze yonke. Ngesiseko sokugcina i-tank yokuqala yamandla aphezulu, Amandla e-composite layer aphindaphindwa kwaye anokusetyenziswa njengesisombululo esitsha sokulungiswa kophahla lwe-oyile kunye negesi yokugcina igesi.
Ukongeza kule mimandla ikhankanywe ngasentla yokunqanda umhlwa, i-prepregs yokunyanga ukukhanya inokusetyenziswa kwakhona kwiindawo zokunqanda ukubola ezifana ne-pool linings kwiindawo eziphantsi komhlaba, imibhobho engaphantsi komhlaba, iitanki zokugcina inkunkuma kwiindawo zokulahla inkunkuma, iidekhi zeenqanawa, kunye nokulungiswa kwezixhobo zombane. Okwangoku, uninzi lwamaphepha okulungiswa kokukhanya kwimarike azimveliso ezivela kumazwe angaphandle, kwaye ixabiso liphezulu, nto leyo enciphisa ukusetyenziswa kwazo. Nangona kunjalo, ngenkxaso karhulumente, ingqalelo yemarike, kunye nokwandiswa kotyalo-mali lophando kunye nezibonelelo zophuhliso, kuya kubakho iintlobo ezininzi ezahlukeneyo zasekhaya ezenziwe ngokukhanya-cured prepreg sheets ezisetyenziswa kwiinkalo ezahlukeneyo.
