Imikhiqizo ye-polyurethane ikakhulukazi ihlanganisa lezi zinhlobo ezilandelayo: amapulasitiki egwebu, ama-elastomers, amaplastiki efayibha, imicu, izinsalela zezicathulo zesikhumba, okokunamathela, okunamathelisa kanye nama-sealant, okuphakathi kwawo amapulasitiki egwebu athatha ingxenye enkulu kakhulu.

ipulasitiki ye-polyurethane enegwebu

Igwebu le-polyurethane lihlukaniswe libe yigwebu eliqinile kanye nezinhlobo ezi-2 zegwebu elithambile, linokuqina okuhle kakhulu, ukunwebeka, amandla acindezelayo nokuthambile, nokuzinza okuhle kwamakhemikhali.Ngaphezu kwalokho, i-polyurethane foam nayo inokusebenziseka okuhle kakhulu, ukunamathela, ukwahlukanisa nezinye izakhiwo, kungokusebenza okuhle kakhulu kwempahla ye-buffer.

Ukukhiqizwa kwezinto ze-polyurethane kusakazeke kulo lonke elaseNyakatho Melika.Kubikwa ukuthi isilinganiso sokukhula kwemakethe ye-polyurethane foam yaseNyakatho Melika kulindeleke ukuthi sifinyelele cishe ku-6%.Ukukhula kulindeleke ukuthi kugxile ekusetshenzisweni kwezindawo zokuhlala nezimboni ze-polyurethane foam efuthwe, kanye nezicelo zezempi ngo-2020. Ngaphezu kwalokho, i-polyurethane izophinde isetshenziswe embonini yezokwelapha ukuze kutholakale ukwelashwa okufika ngesikhathi nangempumelelo kwamanxeba.

i-polyurethane elastomer

Ngenxa yesakhiwo sayo esinezingxenye ezimbili zamaketanga athambile futhi aqinile, ama-polyurethane elastomers anganikezwa amandla aphezulu, ukuqina okuhle, ukumelana nokugqoka, ukumelana nowoyela kanye nezinye izakhiwo ezinhle kakhulu ngokuklanywa kwamaketanga amangqamuzana.I-polyurethane, eyaziwa ngokuthi "injoloba engagugi", inokunwebeka okuphezulu kwerabha kanye nokuqina kwepulasitiki.

Ngonyaka odlule, ngenxa yokwehla okukhulu kwentengo kawoyela ongahluziwe, esimweni sokudangala komnotho emhlabeni wonke, ukukhula kwemakethe ye-polyurethane elastomer ezweni lethu uma kuqhathaniswa neminyaka edlule, ukuthuthukiswa kokuhamba kancane, ukungalingani kokuhlinzekwa. futhi isilinganiso sokufunwa sibangele kakhulu intengo ye-polyurethane elastomer yehle njalo.Kodwa-ke, lesi simo sibonakala kuphela emikhiqizweni yendabuko ye-polyurethane.Okuqukethwe kobuchwepheshe kanye nezinga eliphezulu lokuqanjwa kabusha kwemikhiqizo ye-elastomer efana namathemba emakethe yezinto zokwakha ze-nano polyurethane elastomer, noma kukhulu kakhulu.
