Iphaneli yePU Sandwich eyenziwe ngomatshini

Iphaneli yePU Sandwich eyenziwe ngumatshini eFakelwe umfanekiso

inkcazelo emfutshane:

I-Polyurethane i-foam eqinile yi-isocyanate kunye ne-polyether njengeyona nto iphambili yemathiriyeli, i-agent ye-polyurethane enogwebu itshizwe ngokulinganayo kumgangatho weplate yentsimbi yombala, i-arhente ekhupha ugwebu phakathi kwepleyiti yentsimbi ebumba i-foam ibe yipleyiti elahlayo ye-polyurethane edibeneyo yesandwich.Esi sixhobo esitsha sokwakha ukukhanya kukudibaniswa okugqibeleleyo kombala weplate yensimbi kunye ne-polyurethane, kwaye isetyenziswa ngokubanzi kwizakhiwo zodonga kunye neemfuno zokugquma i-thermal ezifana namagumbi acocekileyo kunye nokugcinwa okubandayo.

Olona phawu luphambili lwePanel yePU Sandwich eyenziwe ngumatshini

Ugwebu oluqinileyo lwePolyurethane okwangoku luvunywa kumazwe ngamazwe njengeyona mathiriyeli igqwesileyo yokugquma.Inomgangatho ophantsi we-thermal conductivity, ukumelana nomthwalo olungileyo, amandla okugoba aphezulu, akukho manzi afunxayo, akukho kubola, akukho mpuku etyiwa zizinambuzane, ukubuyiswa kakuhle kwedangatye kunye noluhlu olukhulu lokumelana nobushushu.

Ikhompyutheni isetyenziselwa ukulawula umgca wemveliso ozenzekelayo ngokupheleleyo, ukwenzela ukuba i-polyurethane ene-foaming ephezulu kunye nepleyiti yentsimbi efakwe umbala yenziwe ngokudibeneyo kwaye idityaniswe ngokuqinileyo.Umbala oqinileyo wentsimbi kunye nezinto ezithambileyo zeekhemikhali zidityaniswe nomatshini wokwenza amagwebu enziwe nge-polyurethane PU ukwenza umatshini wokukhuselwa kwendalo wesayensi kunye nobuchwepheshe bamva nje-i-polyurethane (PU) yombala wesangweji yentsimbi yepaneli, eyiphupha labayili bezakhiwo, abayili kunye neenjineli.

1. I-polyurethane eqinile inobungqina bokufuma kunye neempawu zokungena kwamanzi.Ireyithi evaliweyo yeseli ye-polyurethane eqinile ingaphezulu kwe-90%, eyona nto i-hydrophobic kwaye ayiyi kwandisa i-thermal conductivity ngenxa yokutshatyalaliswa komswakama, kwaye umphezulu wodonga awuyi kukhangela amanzi.

2. Umgangatho we-polyurethane une-conductivity ephantsi ye-thermal kunye nokusebenza kakuhle kwe-thermal.Xa ubuninzi be-polyurethane eqinile yi-38 ~ 42kg / m3, i-thermal conductivity yi-0.018 ~ 0.024w / (mk) kuphela, malunga nesiqingatha se-EPS, kwaye iyona nto iphantsi kuzo zonke izinto zokufakelwa kwe-thermal okwangoku.

3. Ngenxa yokuba ipleyiti yesangweji ye-polyurethane inomsebenzi obalaseleyo wokufudumeza ubushushu, phantsi kweemfuno ezifanayo zokugcinwa kobushushu, inokunciphisa ubukhulu besakhiwo semvulophu yesakhiwo, ngaloo ndlela inyusa indawo yokusetyenziswa kwangaphakathi.

4. Ukusebenza kweendleko ezibanzi eziphantsi.Nangona ixabiso leyunithi ye-polyurethane ye-foam eqinile iphezulu kunezinye izinto zendabuko zokugquma, iindleko ezongeziweyo ziya kuthotywa ngokuncipha okukhulu kweendleko zokufudumeza kunye nokupholisa.
