Ibhodi yokugquma i-XPS yibhodi yeplastiki enogwebu eqinileyo eyenziwe ngentlaka yepolystyrene njengemathiriyeli ekrwada kunye nezinye imathiriyeli ekrwada kunye neepolima, ifudunyezwe kwaye ixutywe kwaye itofwe nge-catalyst ngaxeshanye, ize ikhutshiwe kwaye ibunjwe.Igama layo lezenzululwazi ligwebu lepolystyrene elikhutshiweyo (XPS) lokugquma ubushushu.I-XPS inesakhiwo esipheleleyo se-honeycomb evaliweyo, evumela ibhodi ye-XPS ukuba ibe nokufunxa kwamanzi aphantsi kakhulu (phantse akukho manzi) kunye ne-thermal conductivity ephantsi., Ukuchasana nokunyanzeliswa okuphezulu, ukuchasana nokuguga (phantse akukho nto yokubola ukuguga ekusebenziseni okuqhelekileyo) .Ibhodi ye-XPS inomaleko obunzima obuphezulu kunye nesakhiwo esivaliweyo seseli yangaphakathi.I-conductivity yayo ye-thermal iphantsi kakhulu kune-EPS yobukhulu obufanayo, ngoko inokusebenza okungcono kwe-thermal insulation kune-EPS.

Kwisakhiwo esifanayo sodonga lwangaphandle, ubukhulu bebhodi ye-xps bunokuba buncinci kunezinye iindidi zezinto zokugquma;ngenxa yokwakheka kweeseli ezivaliweyo zomaleko wangaphakathi.Ke ngoko, inokumelana nokufuma okuhle, kwaye isenokugcina ukusebenza kakuhle kokufakwa kwe-thermal kwindawo efumileyo;ifanelekile kwizakhiwo ezineemfuno ezikhethekileyo zokufakelwa kwe-thermal ezifana nokugcinwa okubandayo, kwaye ingasetyenziselwa izakhiwo ezinezitena okanye zamatye ezijongene nodonga lwangaphandle.

Ibhodi ye-polyurethane eqinile ine-conductivity ephantsi ye-thermal kunye nokusebenza kakuhle kwe-thermal.Xa ubuninzi bobuninzi be-polyurethane eqinile yi-35～40kg/m3, i-thermal conductivity yi-0.018g～0.023w/(m·k) kuphela, emalunga nesiqingatha se-EPS, eyona ndlela iphantsi yokuhanjiswa kwe-thermal yazo zonke izinto zokugquma.Ibhodi ye-polyurethane eqinile ayinabumanzi kwaye ayinamanzi.Izinga leeseli ezivaliweyo ze-polyurethane eqinile ingaphezulu kwe-90%, into eyi-hydrophobic, engayi kwandisa i-thermal conductivity ngenxa yokutshatyalaliswa komswakama, kwaye udonga aluyi kubamba amanzi.

Xa kuthelekiswa nezinye izinto zokukhusela, i-polyurethane eqinile i-foam inokusebenza kakuhle kwe-thermal insulation.Ngoko ke, iipaneli ze-sandwich ze-polyurethane ezincinci zinokuhlangabezana nemimiselo echaphazelekayo yokwakha imida yokusetyenziswa kwamandla, evumela ukusetyenziswa kweepaneli ezincinci ngexesha lokwakha, ukugcina indawo yokwakha;umgangatho ozinzile kunye nokusebenza kakuhle kwemveliso.Kwimeko yokunyuka okubukhali kwimfuno, umgca wokuveliswa kwefektri yeepaneli ze-polyurethane sandwich akuncedi kuphela ukulawula umgangatho, kodwa kuzisa uqoqosho oluhle kunye nokukhuphisana.
