Ngaba ukutshiza iPolyurethane kwiMigqomo ngenene kungafakwa i-Thermally Insulated?

Olona hlobo luqhelekileyo lwendlu yeekhonteyina kukubonelela ngekhusi kubasebenzi kwisiza sokwakha.Ngaba banokuzinza ehlotyeni okanye ebusika obubandayo?Akuyi kubanda okanye kushushu?Enyanisweni, nokuba kusehlotyeni okanye kusebusika, izikhongozeli ziyakwazi ukugqunywa.Ukuba awundikholelwa, qhubeka ufunde!

Isikhongozeli ngokwaso asinawo umsebenzi we-thermal insulation.Kuyabanda ebusika kwaye kushushu ehlotyeni.Ehlotyeni, ubushushu bangaphandle bungama-38°, kwaye iqondo lobushushu ngaphakathi kwisikhongozeli lidla ngokufikelela kuma-42°.Ngoko ke, i-thermal insulation layer ibaluleke kakhulu.Emva kokuba indlu yesitya igxininiswe, kuyimfuneko yokongeza i-thermal insulation layer kunye nokufaka izibonelelo zomoya.

Umaleko we-thermal insulation apha utshizwe nge-polyurethane foam eqinile.Kakade ke, kukho ezinye iindlela zokugquma kwe-thermal, ezifana ne-thermal insulation wool, ibhodi yoboya be-rock, ibhodi ye-silicate, njl.

Ke yintoni ukutshiza nge-polyurethane?

Ukutshiza ngePolyurethanekubhekiselele ekusebenziseni umatshini wokutshiza we-polyurethane okhethekileyo wokutshiza izinto eziluhlaza ze-polyurethane phantsi kwesenzo sezongezo ezahlukahlukeneyo ezifana ne-ejenti ekhupha amagwebu, i-catalysts, kunye ne-flame retardants, ngempembelelo yesantya esiphezulu kunye nokujikeleza okunobundlobongela kwigumbi lokuxuba kunye nesithuba esincinci, emva koko udlule. ngokusebenzisa umlomo wesitshizi sompu.Ipholima ephezulu yemolekyuli eyenza amathontsi enkungu ecolekileyo kwaye itshize ngokulinganayo kumphezulu wento.

Ziziphi izinto eziluncedo zokutshiza i-polyurethane kwizikhongozeli?

1. Ukufakwa kwe-thermal, ukusebenza kakuhle okuphezulu kunye nokonga amandla.

I-thermal conductivity ye-polyurethane i-thermal insulation material iphantsi, kwaye ukugcinwa kobushushu kunye nemiphumo yokushisa ukushisa kulungile, okungahambelani nazo naziphi na ezinye izinto zokugquma ukushisa.Kwizakhiwo zokuhlala ngokubanzi, i-polyurethane i-foam eqinile isetyenziswe njengophahla olungangeni manzi kunye nokushisa ukushisa, ubukhulu bayo buyisinye kwisithathu sezinto zemveli, kwaye ukuxhathisa kwayo kwe-thermal kuphantse kuphindwe kathathu kubo.Ngenxa yokuba i-thermal conductivity ye-polyurethane yi-0.022 ~ 0.033W / (m * K kuphela), elingana nesiqingatha sebhodi ekhutshiweyo, kwaye iyona nto iphantsi kwe-thermal insulation coefficient phakathi kwazo zonke izinto zokufakelwa kwe-thermal okwangoku.

2. Umthwalo wophahla ulula.

Izinto zokugquma i-polyurethane zinobunzima obuphantsi kunye nobunzima obulula, ngoko umthwalo ophahleni kunye nodonga ulula.Uphahla lokutshiza i-polyurethane thermal insulation material yikota yendlela yokufulela yendabuko, ebaluleke kakhulu ekuphuculeni isakhiwo esipheleleyo sendlu kunye nokunciphisa iindleko zokwakha, ngoko ke ifaneleka ngakumbi kwizakhiwo ezinkulu kunye nezakhiwo zophahla. .

3. Ukwakhiwa kulungele kwaye inkqubela phambili ikhawuleza.

Itekhnoloji apha i-polyurethane yokutshiza kunye ne-foaming kwi-site, enokusebenza kuyo nayiphi na ukwakhiwa kophahla oluyinkimbinkimbi, oluphindwe kashumi olusebenzayo ngaphezu kokubeka izinto zendabuko.Ikwanciphisa ukuqina kwabasebenzi, iphucule indawo yokusebenza, kwaye inciphisa nokungcoliseka kwendalo.

Umthamo wokwandiswa kwe-foaming kwisiza sezinto zokugquma i-polyurethane ngamaxesha angama-15-18, ngoko ke umthamo wokuthutha wezinto eziluhlaza umncinci.Ngokwezibalo, inokunciphisa iindleko zothutho lwesithuthi ngaphezulu kwe-80% xa kuthelekiswa nokusetyenziswa kwezixhobo zemveli, kwaye ikwanciphisa kakhulu umthwalo wokuhamba ngokuthe nkqo kwindawo yokwakha.

4. Umgangatho olungileyo wobunjineli, ubomi benkonzo ende kunye neendleko eziphantsi

Izinto zokugquma i-polyurethane yi-foam exineneyo ye-microporous enezinga leeseli ezivaliweyo ezingaphezu kwama-92%.Inomzimba ogudileyo kwaye iyimathiriyeli egqwesileyo engenamanzi.Itekhnoloji yokubumba ngokuthe ngqo yokutshiza isetyenziselwa ukwakhiwa ukwenza ukubunjwa okupheleleyo ngaphandle kwemithungo Ukunganyanzeki okupheleleyo ngokusisiseko kuphelisa ukukwazi ukungena kwamanzi ophahleni ngokusebenzisa i-seams.

I-polyurethane i-thermal insulation material inokudibaniswa ngokuqinileyo kwisiseko sesiseko, kwaye amandla ayo okudibanisa anokugqithisa amandla okukrazula kwe-foam ngokwayo, ukwenzela ukuba i-polyurethane yokufakelwa kwe-thermal kunye ne-base layer idibaniswe, kwaye i-delamination ayilula ukuba yenzeke. kunye nokungena kwamanzi ecaleni kwe-interlayer kuyaphetshwa.Izinto zokufakelwa kwe-thermal zendabuko zilula ukufunxa amanzi kunye nomswakama, kwaye ubomi benkonzo yeembrane eziqhelekileyo ezingenamanzi bufutshane kakhulu, kwaye kufuneka zilungiswe rhoqo kwaye zitshintshwe;ngelixa ubomi benkonzo ye-polyurethane ye-thermal insulation materials inokufikelela ngaphezu kweminyaka eyi-10, kwaye iindleko zokugcinwa zigcinwe ngeli xesha likhulu kakhulu.
