Isikhumba sokwenziwa esisetyenziswa ngaphakathi kwemoto ikakhulu sibandakanya i-PVC (i-ployvinyl chloride) yesikhumba sokwenziwa, i-PU (i-poly urethane) yesikhumba sokwenziwa, i-suede njengesikhumba sokwenziwa kunye nezinye iindidi.Yinto engenye yesikhumba kwaye isetyenziswa ngokubanzi kwiindawo zangaphakathi ezifana nezihlalo, iipaneli zomnyango kunye neengubo ezidibeneyo zebhola.
1. ukubumba iPVC
Eyona mathiriyeli ekrwada yePVC yesikhumba eyenziweyo yiPVC, kwaye umzantsi udityaniswe ngelaphu elinithiweyo okanye ilaphu eliphothiweyo.I-PVC ineengenelo zemveliso elula, umgangatho wemveliso efanayo kunye neendleko eziphantsi, kodwa ukunyanzeliswa komoya kunye nokunyameka kokumanzi akubi kuhle njengethwathwa.Inkqubo esisiseko yokubumba imi ngolu hlobo lulandelayo:
① Ukuxuba: I-PVC, i-flame retardant, i-stabilizer kunye nombala ixutywe yimpompo yokucoca.
② Ukwaleka: khetha iphepha elifanelekileyo lokukhulula ngokwendlela yokuthungwa ekhethwe yi template yoyilo, okanye uphinde uphuhlise i-roller yephepha lokukhulula ngokwendlela yokwenza;Ukugquma umxube kwisinyathelo sangaphambili kwiphepha lokukhululwa, ukomisa kunye nokugubungela amaxesha amaninzi ukufikelela kubukhulu obufanelekileyo kunye nokufana;Ekugqibeleni, i-cloth yesiseko esilungisiweyo ihlanganiswe ne-PVC edibeneyo, kwaye emva kokumisa kwakhona, iphepha lokukhulula kunye nelaphu lihlanganiswe ngokulandelanayo.
Umgca we-PVC wokwenziwa kwesikhumba owenziweyo uboniswe kumzobo.
2.Pu ukubumba
Eyona nto iphambili ekrwada yesikhumba eyenziwe ngePu yi-polyurethane, eneempawu zokugcwala, ukomelela okuhle, ukunyanzeliswa komoya okuthile kunye nokunyameka kokunyakama, kwaye isondele ngakumbi ekubunjweni kwesikhumba sendalo.Umgangatho ophezulu wesikhumba owenziwe ngePu ubiza ngakumbi kunesikhumba sokwenyani.Inkqubo yokwenziwa kwesikhumba esiqhelekileyo sePu ifana nePVC.
Olunye uhlobo lwesikhumba sokwenziwa olusetyenziswa kakhulu ngoku yi-superfine fiber PU, ebizwa ngokuba yi-superfine fiber PU ngokufutshane.Ngokwahlukileyo kwisiseko selaphu elinithiweyo lePu eqhelekileyo, isiseko se-super fiber PU lilaphu elingalukwanga elenziwe ngefiber yesiqithi solwandle.I-Island fiber luhlobo lwefiber edibeneyo.Kwicandelo layo le-fiber, i-reinforcements ihlakazekile kwi-substrate njengeziqithi, ngoko kuthiwa.Emva kokuba ilaphu lesiseko sefayibha ephezulu lilukiwe layimilo, lenziwa libe ngumaleko wefiber ephezulu ngokuntywiliselwa kunye nezinye iinkqubo, ezinokwakheka okuphezulu kunePU eqhelekileyo.Inkqubo yokwenziwa kwelaphu lesiseko ibhekisa kwikhonkco:
Imveliso yesikhumba eyenziwe ngePVC
① Ukwaluka: khetha ifiber edibeneyo yesiqithi esifanelekileyo, uyifake ngenaliti, i-spunlace kunye nezinye iindlela zokuluka ezingalukwanga, emva koko uyilonge ngendlela yokwenyama.
②I-impregnation: ilaphu lesiseko elilukiweyo lifakwe kwi-resin, lifakwe, liqiniswe, lihlanjwe, kwaye le nkqubo ingentla iyaphindwa, emva koko iqhutywe kwaye isongiwe ukuvelisa ilaphu lesiseko se-fiber ephezulu.
I-Super fiber PU ifumaneka emva kokuba iPu igqunywe kumphezulu welaphu lesiseko sefayibha.Inkqubo yokwaleka komphezulu iyafana naleyo yePu nePVC eqhelekileyo.
