Iphaneli ye-PU Sandwich eyenziwe ngomshini

incazelo emfushane:

Igwebu eliqinile le-polyurethane liyi-isocyanate kanye ne-polyether njengezinto zokusetshenziswa eziyinhloko, i-ejenti enegwebu ye-polyurethane ifuthwa ngokulinganayo phezu kongqimba lwepuleti lensimbi enombala, i-ejenti ekhihliza amagwebu phakathi kwepuleti lensimbi lombala elibunjwayo libe yipuleti lesemishi eliyinhlanganisela ye-polyurethane elahlwayo.Lesi sakhiwo esisha esikhanyayo siyinhlanganisela ephelele yepuleti lensimbi enombala kanye ne-polyurethane, futhi sisetshenziswa kabanzi ezakhiweni zodonga ezinezidingo zokushisa ezishisayo ezifana namakamelo ahlanzekile nesitoreji esibandayo.

Isici Esiyinhloko Sephaneli ye-PU Sandwich eyenziwe ngomshini

Igwebu eliqinile le-polyurethane njengamanje liqashelwa emhlabeni wonke njengento engcono kakhulu yokufaka umshini wokwakha.Ine-thermal conductivity ephansi, ukumelana nomthwalo omuhle, amandla okugoba aphezulu, awamuncwa amanzi, awaboli, awalunywa amagundane adliwe yizinambuzane, abambezeleka kahle ilangabi kanye nebanga elikhulu lokumelana nezinga lokushisa.

Ikhompiyutha isetshenziselwa ukulawula ulayini wokukhiqiza ozishintshayo ngokugcwele, ukuze i-polyurethane enegwebu eliphezulu eshisa izikhotha kanye nepuleti lensimbi elimbozwe ngombala kwakhiwe ngokuhlangene futhi kuhlanganiswe ngokuqinile.Insimbi enombala oqinile kanye nezinto zokusetshenziswa zamakhemikhali athambile zihlanganiswa nomshini wokwenza igwebu le-polyurethane PU ukuze kwakhiwe iphaneli yesamishi yensimbi yombala yakamuva yesayensi nezobuchwepheshe yokuvikela imvelo-polyurethane (PU), okuyiphupho labaklami bezakhiwo, abaklami nonjiniyela.

1. I-polyurethane eqinile inezinto ezivikela umswakama futhi zingangeni manzi.Izinga leseli elivaliwe le-polyurethane eqinile lingaphezu kuka-90%, okuyimpahla ye-hydrophobic futhi ngeke yandise ukuqhutshwa kwe-thermal ngenxa yokumuncwa komswakama, futhi indawo yodonga ngeke ikhiphe amanzi.

2. Ikhwalithi ye-polyurethane ine-conductivity ephansi yokushisa kanye nokusebenza okuhle kokushisa.Uma ukuminyana kwe-polyurethane eqinile kungu-38~42kg/m3, ukuqhutshwa kwe-thermal kungu-0.018~0.024w/(mk), okucishe kube uhhafu we-EPS, futhi kuphansi kakhulu kuzo zonke izinto zokufakwa ezishisayo okwamanje.

3. Ngenxa yokuthi ipuleti lesangweji le-polyurethane linokusebenza okuhle kakhulu kokufakwa kokushisa, ngaphansi kwezidingo ezifanayo zokulondoloza ukushisa, linganciphisa ukushuba kwesakhiwo semvilophu yokwakha, ngaleyo ndlela kwandise indawo yokusetshenziswa kwangaphakathi.

4. Ukusebenza kwezindleko ezibanzi eziphansi.Nakuba intengo yeyunithi yegwebu eliqinile le-polyurethane iphezulu kunaleyo yezinye izinto ezisetshenziswayo zokufaka ezivamile, izindleko ezikhuphukile zizokhokhiswa ukwehla okukhulu kwezindleko zokushisisa nokupholisa.
