I-resin ye-PVC ye-synthetic leater
I-resin ye-PVC ye-synthetic leater,
I-PVC yesikhumba, i-PVC yesikhumba ekrwada, intlaka yePVC yesikhumba,
Ilaphu lesikhumba lePVC lifana kakhulu nelaphu lesikhumba le-PU.Esikhundleni se-polyurethane, ilaphu lesikhumba le-PVC lenziwe ngokudibanisa i-polyvinylchloride kunye ne-stabilizers (ukukhusela), i-plasticizers (ukuthambisa) kunye ne-lubricants (ukwenza i-flexible), kwaye emva koko isebenzise kwizinto ezisisiseko.
Isikhumba esekwe kwiPVC yeyona ndlela iphambili kwithwathwa lokwenyani.Iveliswa ngokutshintsha iqela le-hydrogen kunye neqela le-chloride kwiqela le-vinyl.Le mveliso ke idityaniswe neekhemikhali ukwenza ufele zokwenziwa.Eyona nto isetyenziswayo kule nkqubo yiPVC.Isikhumba esekwe kwiPVC yayiyeyokuqala yesikhumba eyenziwe ngoo-1920.Kuthathwa njengamandla aphezulu kunye nokumelana neemeko ezahlukeneyo zemozulu.Kuyinto ekulula ukuyigcina kwaye icocekile kwaye ngoko ikhethwa kakhulu kumashishini ahlukeneyo.
Inkqubo yokwenziwa kwesikhumba yePVC
1.indlela yokuqala yindlela yekhalenda.
ngoko ke okokuqala kufuneka sixube i-PVC kunye ne-pigment ekrwada njl njl, kwaye senze izinto ezisemgangathweni oqinileyo.
2.emva koko sigqume izinto ezixubeneyo kwilaphu, de kube yile nkqubo i-semi-finished material siyibiza isiseko sezinto.
ngoko ke izinto ezisisiseko zibandakanya iileya ezi-2: umaleko we-pvc kumphezulu kunye nenkxaso yelaphu.
ke imathiriyeli yesiseko iya kuthunyelwa kumatshini ogwebu amagwebu, ongumgca wemveliso omde kunye nobushushu obuphezulu, izinto ezixubeneyo ziya kuba namagwebu apha, ngoko ke i-pvc iya kuba ngqindilili, ubukhulu bomaleko we-pvc bunokuphinda-phindwe kabini kwisiseko se-pvc.
emva kogwebu, imathiriyeli iya kufakwa ngokuthungwa, apha sisebenzisa i-embossing roller ene-texture kwi-roller, unokucinga ukuba yimbumba, ukuthungwa kwi-roller kuya kudluliselwa kumphezulu we-pvc layer, emva koko sinokufumana ezahlukeneyo. ukuthungwa.
emva koko siya kwenza unyango olungaphezulu, njengokunyenyisa umbala okanye ukushicilela imizobo kumphezulu.
ngezantsi ukuhamba kwemveliso yesikhumba se-pvc
Iimbonakalo
I-PVC yenye yezona zinto zisetyenziswa kakhulu kwi-thermoplastic resins.Ingasetyenziselwa ukwenza iimveliso ezinobunzima obuphezulu kunye namandla, njengemibhobho kunye nokufakelwa, iingcango zeprofayili, iifestile kunye namaphepha okupakisha.Isenokwenza iimveliso ezithambileyo, ezinjengeefilim, amaphepha, iingcingo zombane kunye neentambo, iibhodi eziphantsi kunyengesikhumba sokwenziwa, ngokongezwa kweplastiki
