Ukupheka ubushushu obuphezulu kunye nokuvala inzala yindlela esebenzayo yokwandisa ubomi beshelufu yokutya, kwaye sele isetyenziswe ngokubanzi kwiifektri zokutya ezininzi ixesha elide.Isetyenziswa ngokuqhelekileyobuyisela iipowutshizinezi zakhiwo zilandelayo: PET // AL//PA//RCPP, PET//PA//RCPP, PET//RCPP, PA//RCPP, njl. Isakhiwo sePA//RCPP sisetyenziswa ngokubanzi.Kwiminyaka emibini edlulileyo, iifektri zokutya ezisebenzisa i-PA/RCPP ziye zakhalaza ngakumbi malunga nabavelisi bezinto zokupakisha eziguquguqukayo, kwaye iingxaki eziphambili ezibonakalisiweyo zi-delamination kunye neengxowa eziphukileyo.Ngophando, kufunyaniswe ukuba ezinye iifektri zokutya zinezitenxo ezithile kwinkqubo yokupheka.Ngokubanzi, ixesha lokuvala inzala kufuneka libe yi-30 ~ 40min kubushushu obuyi-121C, kodwa iinkampani ezininzi ezilungisa ukutya azikhathaleli kakhulu malunga nexesha lokuvala inzala, kwaye ezinye zide zifikelele nakwixesha le-90min.
Kwiimbiza zokupheka zokulinga ezithengwe ziinkampani zokupakisha eziguquguqukayo, xa igeyiji yobushushu ibonisa i-121C, ixabiso elibonisa uxinzelelo kwezinye iimbiza zokupheka ngu-0.12 ~ 0.14MPa, kwaye ezinye iimbiza zokupheka ziyi-0.16 ~ 0.18MPa.Ngokutsho kwefektri yokutya, xa uxinzelelo lwembiza yalo yokupheka luboniswa njenge-0.2MPa, ixabiso le-thermometer yi-108C kuphela.
Ukuze kuncitshiswe impembelelo yomgangatho wokungafani kweqondo lokushisa, ixesha kunye noxinzelelo kumgangatho weemveliso zokupheka eziphezulu, ubushushu, uxinzelelo kunye nokuhanjiswa kwexesha lezixhobo kufuneka zilinganiswe rhoqo.Siyazi ukuba ilizwe linenkqubo yokuhlola yonyaka kwiindidi ezahlukeneyo zezixhobo, phakathi kwazo izixhobo zoxinzelelo ziyizixhobo zokuhlola ezinyanzelekileyo zonyaka, kwaye umjikelo wokulinganisa uba kanye emva kweenyanga ezintandathu.Oko kukuthi, phantsi kweemeko eziqhelekileyo, igeyiji yoxinzelelo kufuneka ichaneke.Isixhobo sokulinganisa ubushushu asikho kudidi lohlolo olusisinyanzelo lonyaka, ngoko ke ukuchaneka kwesixhobo sokulinganisa ubushushu kufuneka kuthotywe.
Ulungelelwaniso lwereyiti yexesha nalo kufuneka lulinganiswe ngaphakathi rhoqo.Sebenzisa istopwotshi okanye uthelekiso lwexesha ukulinganisa.Indlela yokulinganisa icetyiswa ngolu hlobo lulandelayo.Indlela yoLungiso: Tofa umlinganiselo othile wamanzi embizeni, fudumeza amanzi ukuba abile ukuya kuthi ga kwinqanaba lokuntywila inzwa yobushushu, kwaye ujonge ukuba isalathiso sobushushu siyi-100C ngeli xesha (kwiindawo eziphakamileyo, iqondo lobushushu kule ndawo. ixesha linokuba ngama-98 ~ 100C) ?Faka indawo yesithemometha esiqhelekileyo ukuze uthelekise.Ukukhulula inxalenye yamanzi ukuveza inzwa yobushushu kumphezulu wamanzi;vala imbiza ngokuqinileyo, nyusa ubushushu ukuya kwi-121C, kwaye ujonge ukuba igeyiji yoxinzelelo lwembiza yokupheka ngeli xesha ibonisa i-0.107Mpa (kwiindawo eziphakamileyo, ixabiso loxinzelelo ngeli xesha lingaba (0. 110 ~ 0. 120MPa) Ukuba le datha ingentla inokuthi ihambelane ngexesha lenkqubo yokulinganisa, oko kuthetha ukuba i-gauge yoxinzelelo kunye neqondo lokushisa kwimbiza yokupheka ikwimeko efanelekileyo.Kungenjalo, kufuneka ucele uchwepheshe ukuba ahlole iwashi yoxinzelelo okanye i-thermometer ukulungiswa.
