PVC tawv (polyvinyl chloride tawv) thiab PU khau tawv (polyurethane khau tawv tawv) yog ob hom hluavtaws tawv tawv uas sib txawv heev hauv kev ua tau zoo thiab zoo li. Kev tsom xam tshwj xeeb yog raws li hauv qab no:
I. Kev ua tau zoo sib txawv
Wearability thiab durability
PVC tawv
High abrasion resistance, high deg hardness, zoo khawb tsis kam tshaj PU, haum rau kev siv ntau zaus (xws li hnab khau txhua hnub).
Txawm li cas los xij, yog tias nws khoov rau lub sijhawm ntev lossis qhov kub thiab txias (xws li lub caij ntuj no khau saum toj), nws yog qhov ua rau brittleness, tawg lossis tawg.
PU tawv tawv
Nruab nrab abrasion kuj tab sis zoo heev yooj. Nws khoov tau yooj yim thiab tsim nyog rau khau (xws li khau ntaub thiab loafers) uas yuav tsum tau ua kom ib ce muaj zog.
Nws muaj kev tiv thaiv kev laus zoo dua li PVC thiab tsis yooj yim rau xim av lossis tawv tom qab siv sijhawm ntev -.
Ua pa yooj yim.
PVC tawv
Cov huab cua permeability tsis zoo thiab cov qauv kaw tsim ib qho kev xav tsis thoob, ua rau nws tsim nyog rau luv luv - siv los yog nrog cov dej tsis haum (xws li khau nag).
PU tawv tawv
zoo breathability. Qee cov khoom lag luam txhim kho hws- kev ua haujlwm tsis zoo los ntawm cov qauv microporous lossis microfiber hauv paus ntaub, ua rau lawv haum rau ntev - hnav ntev (xws li hauv ob sab phlu ntawm khau ntaub).
Kub tiv taus thiab ib puag ncig adaptation
PVC tawv
Tsis zoo kub tsis kam (softening deformation saum toj no 60 degree) thiab tsis kub tsis kam (cracking hauv qab -10 degree).
PU tawv tawv
Nws muaj qhov dav ntawm qhov kub thiab txias (-20C txog 80C), yoog rau huab cua huab cua, yog UV tiv taus ntau dua thiab tsis ploj mus yooj yim.
Ib puag ncig thiab kev nyab xeeb
PVC tawv
Plasticizers, xws li phthalates, tuaj yeem ntxiv rau cov txheej txheem, ua rau muaj kev tsis sib haum xeeb ntawm ib puag ncig. Cov pa phem, xws li dioxins, raug tso tawm thaum hlawv.
PU tawv tawv
VOC emissions tuaj yeem txo qis thiab ua rau ib puag ncig zoo dua los ntawm kev siv tshuab polyurethane hauv dej. Kev sib xyaw ua ke tsim cov pa roj carbon dioxide thiab dej thiab tsis tshua muaj tshuaj lom.
II. Qhov txawv txav
Texture thiab hnov
PVC tawv
Nws muaj glossy tiav, ib qho nyuaj, du thiab zoo ib yam li hauv kev ntxhib los mos rau yas. Nws yog qhov tsim nyog rau kev ua raws li cov tawv nqaij varnished (xws li khau zam).
PU tawv tawv
Qhov kev ntxhib los mos yog ze rau cov tawv nqaij, nrog matte, frosted los yog imitation sheepskin zoo nkauj. Mos thiab springy rau qhov kov.
Kev ua tau zoo ntawm cov xim thiab cov qauv
PVC tawv
xim saturation yog siab, haum rau ci los yog xim hlau xim, tab sis cov txheej txheej ntawm cov qauv kuj tsis muaj zog, feem ntau monochrome los yog luam ntawv yooj yim.
PU tawv tawv
Cov qauv tsis yooj yim (xws li crocodile thiab nab qauv) tuaj yeem ua tiav los ntawm kev hloov luam ntawv thiab embossing, nrog cov xim ntuj hloov thiab muaj zog stereoscopic.
Thickness thiab yooj
PVC tawv
Thickness feem ntau yog nyias (0.2-1.0mm), tab sis nws tsis muaj qhov hloov tau yooj yim thiab khoov tau yooj yim rau hauv lub kaum sab xis tuag.
PU tawv tawv
Nws muaj qhov dav dav dav (0.5-2.0mm) thiab hloov tau yooj yim kom khoov tau yooj yim thiab rov qab mus rau nws cov qauv qub, ua rau nws zoo tagnrho rau lub tso suab vamp tsim.
