I-Polyurethane foam yipolymer ephezulu yemolekyuli.Imveliso eyenziwe kwi-polyurethane kunye ne-polyether exutywe ngobuchule.Ukuza kuthi ga ngoku, kukho iindidi ezimbini zegwebu eliguquguqukayo kunye negwebu eliqinileyo kwimarike.Phakathi kwabo, i-foam eqinile yisakhiwo esivaliweyo, ngelixa i-foam eguquguqukayo iyisakhiwo esivulekileyo.Izakhiwo ezahlukeneyo zinemimandla eyahlukeneyo yesicelo.
Tumsebenzi wakhe we-polyurethane foam
I-polyurethane foam inokudlala indima ephazamisayo.Nokuba igwebu eliqinileyo okanye igwebu elibhetyebhetye, izinto eziphathekayo zilungile kwaye zinokukhuselwa.Ewe kunjalo, inokuba nesiphumo sokugquma kwesandi, kwaye inokusetyenziswa kwezinye iindawo ukwahlula izandi ezithile kakuhle.I-conductivity ephantsi ye-thermal kunye nokusebenza kakuhle kwe-thermal insulation.Kwi-foam eqinile ye-polyurethane foam, kukho izinto eziphathekayo kunye ne-thermal insulation kunye nemisebenzi engenamanzi, eyanciphisa ukuqhutyelwa kwe-thermal.Kweminye imimandla, i-ejenti yokuvuthela ye-thermal ephantsi iyafuneka, kwaye ezinye izinto zokuncamathelisa azifanelekanga ukusetyenziswa.
Iisiceloi-polyurethane foam
Ukonga amandla kunye nokukhuselwa kwendalo.Njengomhluzi, i-gap inokuzaliswa ngokupheleleyo, kwaye ukusebenza okunamathelayo kunokufezekiswa.Emva kokunyanga, inokubambelela ngokuqinileyo kwaye inobomi obude benkonzo.
Uxinzelelo kunye nokothuka.Xa i-polyurethane foam iphiliswe ngokupheleleyo, akuyi kubakho ukukrazula, ukubola kunye nokukhupha.Inoluhlu olubanzi lwezicelo kunye noluhlu olubanzi lokusetyenziswa.Ingasetyenziselwa amandla amatsha, ishishini lomkhosi, unyango lwezonyango, inqwelomoya, iinqanawa, i-electronics, iimoto, izixhobo, izixhobo zombane, uloliwe ohamba ngesantya esiphezulu, njl.Isetyenziswa kwi-elektroniki, unikezelo lwamandla kunye nezinye iindawo, inokuxhathisa ngokufanelekileyo indawo yobushushu obuphezulu kwaye isebenzise ukusebenza kwe-thermal insulation.
Ukukhusela isandi kunye nokugquma.Xa i-polyurethane foam iphiliswe ngokupheleleyo, inokuba bubungqina bokufuma kwaye ingangeni manzi.Nakwimekobume emnyama nefumileyo, akusayi kubakho ngxaki.
