PVC, PU kuyinto PVC (owodwa plastic), kodwa senqubo yokukhiqiza imikhiqizo ezimbili azifani.PVC lesikhumbaOwokuqala uyoba ngo senqubo yokukhiqizaizinhlayiya plasticMelt wabhebhezela ube unama, njengoba kubalulwe emqulwini womthetho ukushuba umfaniswano enamathela phezu T / C wathungela lendwangu substrate, bese esithandweni somlilo yesivini for yesivini, it has ukuzivumelanisa imikhiqizo ehlukene, izidingo ezahlukene umsungulo , kwakhululwa ngasikhathi sinye ekwelapheni kwamanzi (ukudaya, embossed, yona-iphucuziwe, matte, ukugaya ukukhuliswa, ikakhulukazi ngokuhambisana nezidingo eziqondile umkhiqizo).

PU lesikhumba in senqubo yokukhiqiza kukaPVC lesikhumbaNgini eziyinkimbinkimbi, njengoba amandla PU base Indwangu eqine kuyinto ngendwangu enhle PU impahla, ngaphezu the kungenzeka ngenhla camera on the elingaphandle base indwangu, base Indwangu Lungase equkethwe phakathi kangangokuba ekugcineni musa ukubukela ngaphandle ukuba khona indwangu. PU lesikhumbaizakhiwoThanPVC lesikhumbaukumelana Good ukuze esonta kanye ematfuba, ukushintsha-shintsha izinto ezinhle, amandla eqine, abanesimo sokuzinikela permeability air (PVC-free). Kumiswa PVC lesikhumba iphethini ngokucindezela steel iphethini umqulu; PU lesikhumba iphethini iphepha iphetheni yenziwe njani a ukushisa lokuqala yayicindezele ebusweni lesikhumba lulwimi-siphelile, ukulinda ukuze kuphole ngaphambi uhlukanisa iphepha isikhumba, izinto ezingasho lutho processing. PU lesikhumba kuyabiza ngaphezu PVC lesikhumba ukuze okwaba ngaphezu kokuphindwa kabili, PU lesikhumba ezinye izidingo ezikhethekile kuka intengo PVC lesikhumba liphakeme izikhathi ezingu-23. PU lesikhumba ngokuvamile liyadingeka iphethini paper kuyofika ne 45th zilahlwe; umjikelezo eside iphethini roll, ngakho izindleko njengoba ingaphezulu kuka PU lesikhumba PVC lesikhumba.

Ububanzi lezi zinhlobo zezindwangu ababili babe umehluko. NgokoMthetho we nezicathulo, PVC lesikhumba isetshenziswa Linings noma athwale isisindo izingxenye noma izinsimbi izicathulo zezingane; PU izicathulo lingasebenza athwale isisindo lendwangu noma isayithi. Ngamagama izikhwama, kuba ekahle PVC lesikhumba. Lokhu kungenxa yokuthi izinto isikhwama ihlukile izicathulo ukugqoka ezinyaweni, ungasabalalisi ukushisa; musa ithwale isisindo umuntu.

PU, PVC nomahluko indlela kulula ukubona kusuka ekhoneni base lendwangu PU mkhulu kakhulu kunanoma PVC, futhi bazizwa kunomehluko, ezinye zalezi PU soft; PVC Abanye banomuzwa kanzima; ungase futhi usebenzise emlilweni bashise, lo PU ukunambitheka ukwedlula PVC ukunambitha ukukhanya okuningi.
