Igwebu le-polyurethane eliqinile, elibizwa ngokuthi i-polyurethane foam eqinile, lingelesibili kuphela kugwebu oluguquguqukayo lwe-polyurethane enanini lemikhiqizo ye-polyurethane.
Amagwebu e-polyurethane aqinile ngokuvamile ayisakhiwo samaseli avaliwe, anomphumela omuhle wokushisa oshisayo, isisindo esincane, amandla athile aphezulu, ukwakhiwa okulula nezinye izici ezinhle kakhulu.
Ngasikhathi sinye, nazo zinezici zokufakelwa komsindo, ukumelana nokushaqeka, ukwahlukanisa ugesi, ukumelana nokushisa, ukumelana nokubanda, ukumelana ne-solvent, njll., futhi zisetshenziswa kabanzi Izinto zokuvikela amafriji namafriji, isitoreji esibandayo, amaloli esiqandisi, izakhiwo. , amathangi okugcina, kanye namapayipi asetshenziswa ezikhathini ezingafakwanga, njengokhuni lokulingisa, izinto zokupakisha, njll.
Ngokuvamile, igwebu le-polyurethane eliqinile elinokuminyana okuphansi lisetshenziswa kakhulu njengezinto zokuvikela ukushisa (ukugcina ukushisa), kanye negwebu le-polyurethane eliqinile elinomthamo omkhulu lingasetshenziswa njengezinto zokwakha (ukhuni lokulingisa).
Igwebu le-polyurethane eliqinile ngokuvamile lifakwe amagwebu ekamelweni lokushisa, futhi inqubo yokubumba ilula.Ngokwezinga lemishini yokwakha, ingahlukaniswa ibe amagwebu okwenziwa ngesandla kanye ne-mechanical foaming;ngokwengcindezi ngesikhathi sokugwebulwa, ingahlukaniswa ibe amagwebu anomfutho ophakeme kanye nogwebu olunomfutho ophansi;ngokwendlela yokubumba, ingahlukaniswa ngokuthulula amagwebu kanye nokufutha igwebu.
Ukusetshenziswa okuyinhloko kwe-polyurethane i-foam eqinile imi kanje:
1. Imishini yokuqandisa neyokufaka emakhazeni ekudleni nakwezinye izimboni: njengeziqandisi, iziqandisi, indawo yokugcina izinto ezibandayo, amaloli afakwe esiqandisini, njll., igwebu eliqinile le-polyurethane liwumthombo ofaneleka kakhulu wokufaka izinto zokuqandisa nokufaka isiqandisi.
2. Ukufakwa kwemishini yezimboni: njengamathangi okugcina, amapayipi, njll.
3. Izinto zokwakha: Emazweni athuthukile eYurophu naseMelika, igwebu le-polyurethane eliqinile lokwakha libiza cishe ingxenye eyodwa yengqikithi yokusetshenziswa kwegwebu eliqinile, elingaphezu kokukodwa kwenani legwebu eliqinile leziqandisi neziqandisi;e-China, igwebu eliqinile lisetshenziswa embonini yezokwakha.Isicelo asisandile njengasemazweni athuthukile aseNtshonalanga, ngakho-ke amathuba okuthuthukiswa makhulu kakhulu.
4. Imboni yezokuthutha: njengophahla lwezimoto, izingxenye zangaphakathi, njll.
5. Ukhuni lokulingisa: ukuqina okuphezulu (ukuminyana okungu-300^700kg/m3) igwebu eliqinile le-polyurethane noma i-fiber yengilazi eqinisiwe igwebu eliqinile ipulasitiki eyigwebu lesakhiwo, eyaziwa nangokuthi ukhuni lokulingisa, olunamandla aphezulu, ukuqina okuhle, uqweqwe oluminyene noluqinile, inqubo elula yokubumba, Inezici zokusebenza kahle kokukhiqiza okuphezulu, amandla aphezulu kunokhuni lwemvelo, kanye nokuminyana okuphansi kunokhuni lwemvelo.Ingakwazi esikhundleni sezinkuni zemikhiqizo ehlukahlukene ephezulu.
6. Izinto zokubumba, njll.
Noma yimiphi imikhiqizo ye-polyurethane eqinile yegwebu ofuna ukuyenza, wamukelekile ukuthintana nathi, singakunikeza isisombululo esihle kakhulu sephrojekthi.
