Ibhodi lokufaka i-XPS liyibhodi lepulasitiki elinegwebu eliqinile elenziwe nge-polystyrene resin njengempahla eluhlaza kanye nezinye izinto ezingavuthiwe nama-polymers, lishisiswe futhi lixutshwe futhi lijovwe nge-catalyst ngesikhathi esifanayo, bese liyakhishwa futhi libunjwe.Igama layo lesayensi liyigwebu le-polystyrene extruded (XPS) lokufaka ukushisa.I-XPS inesakhiwo esiphelele sezinyosi zamaseli avaliwe, okuvumela ibhodi le-XPS ukuthi libe nokumuncwa kwamanzi okuphansi kakhulu (cishe kungabikho ukumuncwa kwamanzi) kanye nokuhamba okuphansi kwe-thermal., Ukumelana nokucindezelwa okuphezulu, ukulwa nokuguga (cishe akukho mkhuba wokubola kokuguga ekusetshenzisweni okuvamile) .Ibhodi le-XPS linongqimba olungaphezulu oluminyene kanye nesendlalelo sangaphakathi sesakhiwo esivaliwe.I-thermal conductivity yayo iphansi kakhulu kune-EPS yobukhulu obufanayo, ngakho inokusebenza okungcono kwe-thermal insulation kune-EPS.

Ngodonga olufanayo lwesakhiwo sangaphandle, ubukhulu bebhodi le-xps bungaba buncane kunezinye izinhlobo zezinto zokufakelwa;ngenxa yesakhiwo seseli elivaliwe lesendlalelo sangaphakathi.Ngakho-ke, inokumelana nomswakama omuhle, futhi isengakwazi ukugcina ukusebenza kahle kokufakwa kwe-thermal endaweni enomswakama;kufanelekile ezakhiweni ezinezidingo ezikhethekile zokushisa okushisayo ezifana nokugcinwa okubandayo, futhi zingasetshenziselwa izakhiwo ezinezitini noma zamatshe ezibhekene nodonga lwangaphandle.

Ibhodi le-polyurethane eliqinile line-conductivity ephansi ye-thermal kanye nokusebenza okuhle kokushisa.Uma ukuminyana kwenqwaba ye-polyurethane eqinile ingu-35～40kg/m3, i-thermal conductivity ingu-0.018g～0.023w/(m·k) kuphela), okucishe kube uhhafu we-EPS, okuyi-thermal conductivity ephansi kakhulu yazo zonke izinto zokufakelwa.Ibhodi le-polyurethane eliqinile alikwazi umswakama futhi lingangeni manzi.Izinga leseli elivaliwe le-polyurethane eqinile lingaphezu kuka-90%, okuyimpahla ye-hydrophobic, engeke yandise ukuqhutshwa kwe-thermal ngenxa yokumuncwa komswakama, futhi udonga ngeke lukhiphe amanzi.

Uma kuqhathaniswa nezinye izinto zokuvikela, igwebu eliqinile le-polyurethane linokusebenza okuhle kakhulu kokufakwa kwe-thermal.Ngakho-ke, amapaneli amasangweji amancane e-polyurethane angahlangabezana nemithethonqubo efanele ekwakheni imingcele yokusetshenziswa kwamandla, okuvumela ukusetshenziswa kwamapaneli amancane ngesikhathi sokwakhiwa, ukulondoloza indawo yokwakha;izinga elizinzile kanye nokusebenza kahle kokukhiqiza okuphezulu.Endabeni yokwanda okubukhali kwesidingo, umugqa wokukhiqiza wefekthri wamaphaneli we-polyurethane sandwich awugcini nje ngokusiza ukulawulwa kwekhwalithi, kodwa futhi uletha umnotho omuhle nokuncintisana.
