I-Polyurethane foam yipolymer ephezulu yemolekyuli.Imveliso eyenziwe kwi-polyurethane kunye ne-polyether exutywe ngobuchule.Ukuza kuthi ga ngoku, kukho iindidi ezimbinibhetyebhetye ugwebu kwayengqongqo ugwebu kwimarike.Phakathi kwabo, i-foam eqinile yi-a iseli evaliweyoubume, ngelixa ibhetyebhetye ugwebu yiiseli evulekileyo isakhiwo.Izakhiwo ezahlukeneyo zinemimandla eyahlukeneyo yesicelo.
Tumsebenzi wakhe we-polyurethane foam
Pi-olyurethane foam inokudlala indima yokuthintela.Nokuba kunjalongqongqo ugwebu okanyebhetyebhetye igwebu, imathiriyeli ilungile kwaye inokukhuselwa.Kakade ke, inokuba nayo aukugquma isandi isiphumo, kwaye inokusetyenziswa kwezinye iindawo ukwahlula izandi ezithile kakuhle kakhulu.I-conductivity ephantsi ye-thermal kunye nokusebenza kakuhle kwe-thermal insulation.Kwi-foam eqinile ye-polyurethane foam, kukho izinto eziphathekayoukufakwa kwe-thermal kwayeinto evikela amanzi imisebenzi, ecutha conductivity thermal.Kweminye imimandla, i-ejenti yokuvuthela ye-thermal ephantsi iyafuneka, kwaye ezinye izinto zokuncamathelisa azifanelekanga ukusetyenziswa.
Iisicelo i-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-foam ye-polyurethane 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.
