Ukupheka kwezinga lokushisa eliphezulu nokuvala inzalo kuyindlela ephumelelayo yokwandisa impilo yeshalofu yokudla, futhi sekusetshenziswe kabanzi izimboni eziningi zokudla isikhathi eside.Okuvame ukusetshenziswabuyisela izikhwamababe nezakhiwo ezilandelayo: PET//AL//PA//RCPP, PET//PA//RCPP, PET//RCPP, PA//RCPP, njll. Isakhiwo se-PA//RCPP sisetshenziswa kabanzi.Eminyakeni emibili edlule, izimboni zokudla ezisebenzisa i-PA/RCPP zikhalaze kakhulu mayelana nabakhiqizi bezinto zokupakisha eziguquguqukayo, futhi izinkinga eziyinhloko eziboniswayo yi-delamination nezikhwama eziphukile.Ngophenyo, kutholakala ukuthi ezinye izimboni zokudla zinokungahambi kahle ekuphekeni.Ngokuvamile, isikhathi sokuvala inzalo kufanele sibe ngu-30 ~ 40min ekushiseni kuka-121C, kodwa izinkampani eziningi ezilungisa ukudla azinaki neze ngesikhathi sokuvala inzalo, futhi ezinye zize zifinyelele isikhathi sokuvala inzalo esingu-90min.
Emabhodweni okuhlola okupheka athengwe izinkampani zokupakisha eziguquguqukayo, lapho izinga lokushisa libonisa u-121C, inani elibonisa ingcindezi lamanye amabhodwe okupheka lingu-0.12 ~ 0.14MPa, kanti amanye amabhodwe okupheka angu-0.16 ~ 0.18MPa.Ngokusho kwefekthri yokudla, lapho umfutho webhodwe layo lokupheka uboniswa njengo-0.2MPa, inani elibonisa izinga lokushisa lingu-108C kuphela.
Ukuze kuncishiswe umthelela wekhwalithi wokuhluka kwezinga lokushisa, isikhathi kanye nokucindezela kwikhwalithi yemikhiqizo yokupheka eshisa kakhulu, izinga lokushisa, ingcindezi kanye nokudluliselwa kwesikhathi kwezinto zokusebenza kufanele kulinganiswe njalo.Siyazi ukuthi izwe linohlelo lokuhlola lwaminyaka yonke lwezinhlobo ezahlukene zamathuluzi, phakathi kwazo amathuluzi okucindezela okungamathuluzi okuhlola onyaka ayimpoqo, futhi umjikelezo wokulinganisa uba kanye njalo ezinyangeni eziyisithupha.Okusho ukuthi, ngaphansi kwezimo ezijwayelekile, isilinganiso sokucindezela kufanele sibe nembe ngokuqhathaniswa.Ithuluzi lokulinganisa izinga lokushisa alikho esigabeni sokuhlolwa konyaka okuyisibopho, ngakho-ke ukunemba kwethuluzi lokulinganisa izinga lokushisa kufanele kwehliswe.
Ukulinganiswa kokudluliselwa kwesikhathi nakho kudinga ukulinganiswa ngaphakathi njalo.Sebenzisa isitophuwashi noma ukuqhathanisa isikhathi ukuze ulinganise.Indlela yokulinganisa iphakanyiswa kanje.Indlela yokulungisa: Faka inani elithile lamanzi ebhodweni, shisisa amanzi aze abile aze angakwazi ukucwilisa inzwa yokushisa, futhi uhlole ukuthi inkomba yokushisa ingu-100C ngalesi sikhathi (ezindaweni eziphakeme, izinga lokushisa kulokhu isikhathi singase sibe ngu-98 ~ 100C) ?Faka esikhundleni se-thermometer evamile ukuze uqhathanise.Khipha ingxenye yamanzi ukuze uveze inzwa yokushisa endaweni yamanzi;vala ibhodwe ngokuqinile, ukhuphule izinga lokushisa libe ku-121C, bese ubheka ukuthi ingabe igeji yokucindezela ebhodweni lokupheka ngalesi sikhathi ikhombisa u-0.107Mpa (ezindaweni eziphakeme kakhulu, inani lokucindezela ngalesi sikhathi lingaba (0. 110 ~ 0. 120MPa) . Uma idatha engenhla ingashintshashintsha phakathi nenqubo yokulinganisa, kusho ukuthi igeji yokucindezela kanye ne-temperature gauge yebhodwe lokupheka kusesimweni esihle. Uma kungenjalo, kufanele ucele uchwepheshe ukuthi ahlole iwashi lokucindezela noma izinga lokushisa ukuze lilungiswe.
