Namuhla abanikazi bezimoto abaningi ngokwengeziwe ekukhetheni ingaphakathi lemoto yezimoto zabo, badidekile ngokuthi bangakhetha kanjani phakathi kwesikhumba se-PU nesikhumba se-PVC, namuhla sizohlaziya kusuka ezicini eziningana ze-PU ne-PVC ekugcineni ukuthi yini umehluko.
Ukwethulwa kwe-PU Isikhumba:
Isikhumba se-polyurethane, esivame ukubizwa ngokuthiIsikhumba se-PU, ngiisikhumba sokwenziwa.Yenziwe nge-thermoplastic polymer futhi isetshenziselwa ukwenza izicathulo nefenisha.Isikhumba se-PUiyinhlanganisela yamakhemikhali ahlukahlukene okwenziwa;yingakho i-100% ye-vegan.Inokwakheka okufanayo njengesikhumba sangempela, kodwa ikakhulukazi ilula, ayihlali isikhathi eside, futhi imelana kakhulu nokukhanya kwelanga.
Ukwethulwa kwesikhumba se-PVC:
Isikhumba se-PVC, noma ngezinye izikhathi ebizwa ngokuthi i-Vinyl, yenziwe ngendwangu yesikhumba esekelwe, ifakwe ungqimba lwegwebu, ungqimba lwesikhumba bese kuba i-plastic based surface coating.
I-PVCiyimpushana emhlophe enesakhiwo se-amorphous, i-branched degree encane, ukuminyana kwesihlobo mayelana ne-1.4, izinga lokushisa lokushintsha kwengilazi 77 ~ 90 ℃, ukubola kuqala cishe ku-170 ℃, ukuqina okubuthakathaka ekukhanyeni nasekushiseni, ngaphezu kwe-100 ℃ noma ngokuchayeka kwelanga isikhathi eside, kuzokwenza ukubola futhi kukhiqize i-hydrogen chloride, futhi okunye ukubola kwe-auto-catalytic, okubangela ukushintsha kombala, izakhiwo zomzimba nezomshini nazo zehla ngokushesha, ekusebenziseni okungokoqobo kufanele kwengezwe I-Stabilizer kumele yengezwe ukuze kuthuthukiswe ukuzinza kokushisa nokukhanya.
Isikhumba se-PUVSIsikhumba se-PVC:
●Inqubo Yokukhiqiza
✧PVC isikhumba: Enqubweni yokukhiqiza, ama-granules epulasitiki kufanele ancibilike ashise futhi agxiliswe abe unama, ambozwe ngokulinganayo phezu kwe-T / C knitted substrate ngokusho kobukhulu obucacisiwe, abese efakwa esithandweni esinegwebu ukuze sigcwale amagwebu. ubumnene obungakwazi ukuzivumelanisa nokukhiqizwa kwemikhiqizo ehlukahlukene kanye nezidingo ezahlukene, futhi ukwelashwa kwendawo kwenziwa ngesikhathi esifanayo njengoba isithando somlilo sikhishwa.
✧PU lesikhumba: In the inqubo yokukhiqiza kukaIsikhumba se-PVCkuyinkimbinkimbi kakhulu, ngoba ukusekelwa kwe-PU kuyikhanvasi yamandla eqinileIzinto ze-PU, ngaphezu kokungaphezulu kokusekela kungenziwa kuhlanganiswe, kodwa futhi ukusekela kungaqukatha phakathi, ukuze ngaphandle kungaboni ukuba khona kwendwangu engezansi.
●Engokomzimba
✧PU Isikhumba: Izakhiwo zomzimba zingcono kunesikhumba se-PVC, ukumelana nokuguquguquka, ukuguquguquka okuhle, amandla aphezulu, ukuphefumula.
✧Isikhumba se-PVC: Ukuzinza okuhle kanye nezakhiwo ze-dielectric, ezihlala isikhathi eside futhi ezilwa nokuguga, kulula ukuhlanganisa nokubopha.
●Intengo
Intengo yeIsikhumba se-PUingaphezu kokuphindwe kabili kwalokho kweIsikhumba se-PVC, kanye nentengo yesikhumba esithile esikhethekile se-PU, njengemicrofiber lesikhumba, iphakeme izikhathi ezingu-2-3 kunesikhumba se-PVC.Ngokuvamile, iphepha lephethini elidingekayo lesikhumba se-PU lingasetshenziswa kuphela izikhathi ezingu-4-5, futhi i-roller yephethini inomjikelezo wempilo omude, ngakho-ke izindlekoIsikhumba se-PUiphakeme kunaleyo yeIsikhumba se-PVC.
● Ububanzi bohlelo lokusebenza
✧Isikhumba se-PVC: Isikhumba se-PVC sisetshenziswa kakhulu ulwelwesi noma izingxenye ezingathwali isisindo, njengesembozo sesihlalo semoto nomata bezinyawo zemoto.
Isikhumba se-✧PU: Isikhumba se-PU singasetshenziswa engxenyeni enesisindo somhlobiso wemoto, njengesondo lokuqondisa imoto, uphahla kanye nesembozo sesihlalo semoto.
● Ukumelana nezinga lokushisa
✧PU lesikhumba: Ukushisa okuphezulu ukumelana kungafinyelela ku-90 ℃.
✧PVC lesikhumba: Ukushisa okuphezulu ukumelana 65℃.
●Ukuthamba
Ukuthamba kwesikhumba se-PU kuthambile uma kuqhathaniswa nesikhumba se-PVC, isikhumba se-PVC singakwazi ukwengeza i-plasticizer ukuze siyenze sithambile, i-plasticizer iyisengezo ukwenza i-PVC ithambe, kodwa izindinganiso zokudla zinezidingo eziqinile zokuqukethwe kwe-plasticizer, ngakho-ke i-PVC ethambile, i-plasticizer empeleni kude nokuhlangabezana nezidingo zemvelo.
●Izingxenye
Isikhumba se-✧PU: I-Polyurethane, igama eliyiqoqo lochungechunge lwezinto zokwakha ze-polyurethane (i-polyurethane), into ekhulayo ye-polymer ephilayo, eyaziwa ngokuthi "ipulasitiki enkulu yesihlanu".Izinto zokusetshenziswa eziyinhloko ze-polyurethane synthesis yi-organic polyisocyanates kanye ne-end-hydroxy compounds.
✧Isikhumba se-PVC: I-Polyvinyl chloride, noma i-polyvinyl chloride, i-polymer eyakhiwe yi-polymerization ye-vinyl chloride monomer (VCM) phambi kweziqalisi ezifana nama-peroxides nama-azo compounds, noma phambi kokukhanya noma ukushisa ku-polymerization yamahhala yamahhala. indlela yokusabela.Ama-homopolymers e-vinyl chloride nama-copolymers e-vinyl chloride ngokuhlangene abizwa ngokuthi ama-vinyl chloride resins (ama-PVC resins).
●Ukunambitheka
✧PU Isikhumba: Uma ushisa i-PU ngomlilo, iphunga layo lilula.
✧Isikhumba se-PVC: Uma ushisa i-PVC ngomlilo, izophenduka ibe mnyama futhi ihambisane nephunga elinamandla kakhulu.
Lena indawo ka-BensenIsikhumba se-PUfuthiIsikhumba se-PVC, ngamandla amakhulu nokuzinza okuhle kakhulu, futhi okungashi, kungamelana nokugqwala okulethwa ukushintsha kwesimo sezulu, okusetshenziselwa kabanzi ekuhlobiseni izinto zangaphakathi zezimoto.Ungakwazi njalo ukukhetha impahla oyithandayo futhi efanele imoto yakho.
Uma udinga, sicela ukhululeke ukuxhumana nathi.
