Niaj hnub no ntau thiab ntau tus tswv tsheb nyob rau hauv kev xaiv ntawm lub tsheb sab hauv rau lawv lub tsheb, tsis meej pem txog yuav ua li cas xaiv ntawm PU tawv thiab PVC tawv, hnub no peb yuav soj ntsuam los ntawm ob peb yam ntawm PU thiab PVC nyob rau hauv lub kawg yog dab tsi yog qhov txawv.
Taw qhia ntawm PU tawv:
Polyurethane tawv, feem ntau hu uaPU tawv, yogtawv tawv.Nws yog tsim los ntawm thermoplastic polymer thiab yog siv los ua khau thiab rooj tog.PU tawvyog ib qho kev sib xyaw ntawm ntau yam khoom siv dag zog;Yog vim li cas nws yog 100% vegan.Nws muaj qhov zoo tib yam li tawv tawv, tab sis feem ntau nws yog sib dua, tsis tshua muaj zog, thiab tiv taus tshav ntuj.
Taw qhia ntawm PVC Tawv:
PVC tawv, los yog qee zaum hu ua Vinyl, yog ua los ntawm cov ntaub tawv tawv rov qab, topped nrog npuas txheej, txheej tawv nqaij thiab tom qab ntawd cov yas raws li txheej txheej.
PVCyog cov hmoov dawb nrog cov qauv amorphous, me me branched degree, txheeb ze ntom ntom txog 1.4, iav hloov pauv kub 77 ~ 90 ℃, decomposition pib nyob ib ncig ntawm 170 ℃, tsis zoo stability rau lub teeb thiab kub, siab tshaj 100 ℃ los yog los ntawm lub sij hawm ntev tshav ntuj raug, nws yuav decompose thiab tsim hydrogen chloride, thiab ntxiv nws pib-catalytic decomposition, ua rau discoloration, lub cev thiab txhua yam khoom kuj poob sai, nyob rau hauv kev siv tswv yim yuav tsum tau ntxiv Stabilizer yuav tsum tau ntxiv los txhim kho stability ntawm tshav kub thiab lub teeb.

●Kev tsim khoom
✧ PVC tawv: Hauv kev tsim cov txheej txheem, cov yas granules yuav tsum tau kub-melted thiab nplawm rau hauv ib qho muab tshuaj txhuam, sib npaug ntawm T / C knitted npuag substrate raws li cov tuab tuab, thiab tom qab ntawd nkag mus rau hauv lub qhov cub foaming rau foaming, kom nws muaj ib tug softness uas tuaj yeem hloov kho rau ntau yam khoom thiab cov kev xav tau sib txawv, thiab kev kho saum npoo yog nqa tawm tib lub sijhawm thaum lub qhov cub tawg.
✧ PU tawv: Hauv kev tsim khoom duaPVC tawvNws yog qhov nyuaj me ntsis, vim tias PU rov qab yog qhov zoo tensile lub zog canvasPU khoom, nyob rau hauv tas li ntawd mus rau sab saum toj ntawm lub nraub qaum tuaj yeem coated, tab sis kuj lub nraub qaum tuaj yeem muaj nyob hauv nruab nrab, kom sab nraud tsis tuaj yeem pom qhov muaj nyob ntawm daim ntaub hauv qab.
● Lub cev
✧ PU tawv: Lub cev muaj zog zoo dua li PVC tawv, flexural tsis kam, zoo yooj, siab tensile zog, breathability.
✧ PVC tawv: zoo stability thiab dielectric zog, ruaj thiab tiv thaiv kev laus, yooj yim rau fuse thiab daim ntawv cog lus.
● Nqe
Tus nqi ntawmPU tawvyog ntau tshaj ob npaug ntawmPVC tawv, thiab tus nqi ntawm ib co tshwj xeeb PU tawv, zoo limicrofiber tawv, yog 2-3 zaug siab dua li ntawm PVC tawv.Feem ntau, cov qauv ntawv xav tau rau PU tawv tsuas yog siv tau 4-5 zaug, thiab cov qauv rau cov menyuam muaj lub neej ntev, yog li tus nqi ntawmPU tawvyog siab tshaj li ntawmPVC tawv.
● Scope ntawm daim ntawv thov
✧ PVC tawv: PVC tawv feem ntau yog siv rau hauv ob sab phlu lossis tsis hnyav qhov hnyav, xws li lub rooj zaum hauv tsheb thiab lub tsheb ko taw mats.
✧ PU tawv: PU tawv tuaj yeem siv rau qhov hnyav ntawm lub tsheb kho kom zoo nkauj, zoo li lub log tsheb, lub ru tsev thiab lub rooj zaum hauv tsheb.
● Kub ua hauj
✧ PU tawv: Qhov kub siab tshaj plaws tuaj yeem ncav cuag 90 ℃.
✧ PVC tawv: Qhov siab tshaj plaws kub tsis kam 65 ℃.
●Kev mos
Lub softness ntawm PU tawv yog softer rau qhov kov piv rau PVC tawv, PVC tawv muaj peev xwm ntxiv plasticizer kom nws softer, plasticizer yog ib tug additive los ua PVC softer, tab sis cov qauv zaub mov muaj nruj raws li cov ntsiab lus ntawm plasticizer, yog li mos PVC, plasticizer yog. ua tau deb ntawm ua tau raws li ib puag ncig yuav tsum tau.
●Cheebtsam
✧ PU tawv: Polyurethane, yog lub npe sib sau ua ke ntawm cov khoom siv polyurethane (polyurethane), cov khoom siv organic polymer, hu ua "thib tsib loj yas".Lub ntsiab raw khoom rau polyurethane synthesis yog organic polyisocyanates thiab end-hydroxy compounds.
✧ PVC tawv: Polyvinyl chloride, los yog polyvinyl chloride, yog ib tug polymerization ntawm lub polymerization ntawm vinyl chloride monomer (VCM) nyob rau hauv lub xub ntiag ntawm pib xws li peroxides thiab azo tebchaw, los yog nyob rau hauv lub xub ntiag ntawm lub teeb los yog kub nyob rau hauv ib tug dawb radical polymerization. tshuaj tiv thaiv mechanism.Vinyl chloride homopolymers thiab vinyl chloride copolymer yog sau ua ke hu ua vinyl chloride resins (PVC resins).
●Flavour
✧ PU tawv: Yog tias koj hlawv PU nrog hluav taws, nws tsis hnov tsw.
✧ PVC tawv: Yog tias koj hlawv PVC nrog hluav taws, nws yuav tig dub thiab nrog cov ntxhiab tsw heev.
Bensen covPU tawvthiabPVC tawv, nrog lub zog siab thiab zoo heev stability, thiab tsis-flammable, tuaj yeem tiv thaiv corrosion coj los ntawm kev hloov pauv huab cua, dav siv hauv kev kho kom zoo nkauj ntawm tsheb sab hauv.Koj tuaj yeem xaiv ib yam khoom uas koj nyiam thiab haum rau koj lub tsheb.
