Ingabe Ukufafaza I-Polyurethane Ezitsheni Kungagqunywa Nge-Thermally Ngempela?

Uhlobo oluvame kakhulu lwendlu yeziqukathi ukuhlinzeka ngokukhosela kubasebenzi endaweni yokwakha.Bangakwazi yini ukuhlala ehlobo elishisayo noma ebusika obubandayo?Ngeke kubande noma kushise?Eqinisweni, noma ngabe kusehlobo noma kusebusika, iziqukathi nazo zingavalwa.Uma ungangikholwa, qhubeka ufunde!

Isiqukathi ngokwaso asinawo umsebenzi we-thermal insulation.Kuyabanda ebusika futhi kuyashisa ehlobo.Ehlobo, izinga lokushisa langaphandle lingama-38°, kanti izinga lokushisa ngaphakathi kwesiqukathi livame ukuba phezulu libe ngu-42°.Ngakho-ke, ungqimba lwe-thermal insulation lubaluleke kakhulu.Ngemuva kokuthi indlu yesiqukathi isilungisiwe, kuyadingeka ukwengeza isendlalelo se-thermal insulation futhi ufake izinsiza zomoya.

Ungqimba lwe-thermal insulation lapha lufafazwa ngegwebu eliqinile le-polyurethane.Yiqiniso, kunezinye izindlela zokushisa ezishisayo, ezifana noboya obushisayo obushisayo, ibhodi le-rock wool, ibhodi le-silicate, njll. Ukukhetha ikakhulukazi kuncike ekusebenziseni kwakho kwangempela.

Ngakho-ke yini i-polyurethane spraying?

Ukufafaza nge-polyurethaneibhekisela ekusebenziseni umshini wokufafaza we-polyurethane okhethekile ukufafaza izinto zokusetshenziswa ze-polyurethane ngaphansi kwesenzo sezithasiselo ezihlukahlukene ezifana nama-foaming agents, ama-catalysts, nama-flame retardants, ngokusebenzisa umthelela wesivinini esikhulu nokuzungeza okunobudlova ekamelweni lokuxuba elinendawo encane, bese udlula. ngombhobho wesibhamu sokufutha.I-polymer ye-molecular ephakeme eyenza amaconsi enkungu acolisekile bese ifutha ngokulinganayo phezu kwento.

Yiziphi izinzuzo zokufafaza i-polyurethane ezitsheni?

1. Ukushisa okushisayo, ukusebenza kahle okuphezulu nokonga amandla.

I-thermal conductivity ye-polyurethane thermal insulation material iphansi, futhi ukugcinwa kokushisa kanye nemiphumela yokushisa ukushisa kuhle, okungenakuqhathaniswa nanoma yiziphi ezinye izinto zokushisa ezishisayo.Ezakhiweni zokuhlala ezijwayelekile, i-polyurethane i-foam eqinile isetshenziswa njengophahla olungangeni manzi noluvikela ukushisa, ukujiya kwalo kuyingxenye eyodwa kwezintathu kuphela kwezinto zendabuko, futhi ukumelana nokushisa kwalo cishe kuphindwe kathathu kunabo.Ngenxa yokuthi i-thermal conductivity ye-polyurethane ingu-0.022~0.033W/(m*K) kuphela, okulingana nengxenye yaleyo yebhodi elikhishiwe, futhi iyi-coefficient ephansi yokufakwa kwe-thermal phakathi kwazo zonke izinto zokufaka ukushisa okushisayo okwamanje.

2. Umthwalo ophahleni ulula.

I-polyurethane insulation material inesisindo esincane nesisindo esincane, ngakho-ke umthwalo ophahleni nodonga ulula.Uphahla lokufafaza i-polyurethane thermal insulation material luyingxenye yesine yendlela yokufulela yendabuko, ebaluleke kakhulu ukuthuthukisa isakhiwo sonke sendlu nokunciphisa izindleko zokwakha, ngakho-ke ifaneleka kakhulu izakhiwo zophahla ezinkulu nezincane ezinamagobolondo amancane. .

3. Ukwakhiwa kulula futhi intuthuko iyashesha.

Ubuchwepheshe lapha yi-polyurethane spraying kanye ne-foaming on-site, engasebenza kunoma yikuphi ukwakhiwa kophahla oluyinkimbinkimbi, okusebenza izikhathi eziyishumi ngaphezu kokubeka izinto zendabuko.Kuphinde kwehlise izinga labasebenzi, kuthuthukise indawo yokusebenza, futhi kunciphise nokungcoliswa kwemvelo.

Ivolumu yokunwetshwa kwe-foaming esizeni yezinto zokufakelwa kwe-polyurethane izikhathi eziyi-15-18, ngakho-ke umthamo wokuthutha wezinto zokusetshenziswa mncane.Ngokwezibalo, kunganciphisa izindleko zokuthutha imoto ngaphezu kuka-80% uma kuqhathaniswa nokusetshenziswa kwezinto ezisetshenziswayo zendabuko, futhi futhi kunciphisa kakhulu umthwalo wokuhamba okuma mpo lapho kwakhiwa khona.

4. Ikhwalithi enhle yobunjiniyela, impilo ende yesevisi kanye nezindleko eziphansi

I-polyurethane insulation material iyigwebu eliminyene le-microporous elinezinga leseli elivaliwe elingaphezu kwama-92%.Inobushelelezi bokuzesula futhi iyinto enhle kakhulu engangeneki.Ubuchwepheshe bokubumba okufafaza okuqondile busetshenziswa ekwakhiweni ukwenza ukwakheka okuphelele ngaphandle kwama-seams Ukungangenisi okuphelele kuqeda ngokuyisisekelo ukuthi kungenzeka ukuthi amanzi ophahleni angene nge-seams.

I-polyurethane thermal insulation material ingahlanganiswa ngokuqinile nesendlalelo sesisekelo, futhi amandla ayo okubopha angadlula amandla okudabula igwebu ngokwalo, ukuze i-polyurethane thermal insulation material kanye ne-base layer ihlanganiswe, futhi i-delamination akulula ukwenzeka, futhi ukungena kwamanzi eduze kwe-interlayer kuyagwenywa.Izinto zendabuko zokushisa ezishisayo kulula ukumunca amanzi kanye nomswakama, futhi impilo yesevisi ye-membrane evamile engenamanzi ifushane kakhulu, futhi kufanele ilungiswe njalo futhi ishintshwe;kuyilapho impilo yesevisi yezinto zokufakelwa ezishisayo ze-polyurethane ingafinyelela eminyakeni engaphezu kwe-10, futhi izindleko zokulondoloza ezongiwe ngalesi sikhathi zikhulu kakhulu.
