Ama-polyurethanes ama-polymers asetshenziswa kakhulu akhiwa ngokuphendula ama-polyols ane-disocyanate phambi kwamakhemikhali afana nama-catalysts kanye nezithasiselo.Asetshenziselwa ukukhiqiza imikhiqizo ehlukahlukene cishe kuzo zonke izimboni, njengezogesi, ezezimoto, izicathulo, ezokwakha, zokupakisha, njll., ukuze zibunjwe zibe yizimo ezingajwayelekile futhi zithuthukise imikhiqizo yabathengi neyezimboni.
I-polyurethane isetshenziswa njengegwebu eliqinile lezindonga nokufakwa kophahla, igwebu eliguquguqukayo kwifenisha, nanjengezinto zokunamathisela, okokunamathela, nezinsimbi zokuvala ngaphakathi kwezimoto.Zonke lezi zici kungenzeka zinikeze inzuzo121 BPSemakethe ye-polyurethane phakathi neminyaka yokubikezela ka-2022-2032.
Ukusetshenziswa okuyinhloko kwe-polyurethane kuma-elastomers, amagwebu, nama-coatings anikeza ukumelana okuhle kakhulu kokuhuzuka.Amagwebu e-polyurethane aqinile asetshenziswa kabanzi njengezinto zokufakelwa ngenxa yokuhlanganiswa kokungabizi kahle kanye nempahla yokudlulisa ukushisa okuphansi.Amandla amahle wezinga lokushisa eliphansi, ukuhlukahluka okubanzi kwesakhiwo samangqamuzana, izindleko eziphansi, nokumelana nokuhuzuka okuphezulu konke kusekela ukukhula kwemakethe.
Kodwa-ke, isimo sezulu esibi, amandla amancane okushisa, ukuvutha, njll., kungenzeka kuphazamise ukukhula kwesidingo se-polyurethane eminyakeni ezayo.
Isimemezelo:Okunye okuqukethwe/izithombe kulesi sihloko zivela ku-inthanethi, futhi umthombo uqashelwe.Zisetshenziselwa kuphela ukukhombisa amaqiniso noma imibono eshiwo kulesi sihloko.Ezokuxhumana nokufunda kuphela, futhi azizona ezinye izinjongo zentengiso.Uma kukhona ukwephulwa komthetho, sicela usithinte ukuze sikususe ngokushesha.
