uas yog ntau ntxeem tau polyurethane los yog pvc vinyl tawv
Mar 07, 2024
Polyurethane thiab PVC yas tawv yog ob qho khoom siv nrov siv hauv kev tsim khoom ntawm ntau yam khoom. Ob qho khoom siv muaj lawv cov yam ntxwv tshwj xeeb, tab sis ib qho tseem ceeb sib txawv ntawm ob yog lawv qhov porousness.
Polyurethane yog cov khoom siv hluavtaws uas muaj zog heev thiab tuaj yeem ua rau ntau hom. Polyurethane muaj cov qauv qhib-hlwb, uas ua rau nws ntxeem tau ntau dua li PVC vinyl tawv. Cov qauv qhib-cell no txhais tau hais tias cov khoom tso cai rau huab cua thiab noo noo dhau mus, muab nws zoo dua breathability. Yog li ntawd, polyurethane yog ib qho khoom siv zoo heev rau kev ua cov khoom uas xav tau qhov cua zoo li khau, hnab, thiab upholstery.
Ntawm qhov tod tes, PVC vinyl tawv muaj cov qauv kaw, lub ntsiab lus nws muaj qhov porosity tsawg piv rau polyurethane. PVC vinyl tawv yog ua los ntawm ob peb txheej ntawm cov khoom siv hluavtaws xws li polyester lossis nylon, tom qab ntawd coated nrog PVC kom ua tau raws li qhov xav tau kev ntxhib los mos, xim, thiab dej tsis kam. PVC vinyl tawv yog qhov ruaj khov thiab tuaj yeem tiv taus hnav thiab tsim kua muag zoo dua li polyurethane. Nws yog, yog li ntawd, ib qho kev xaiv zoo tshaj plaws rau cov khoom uas xav tau ntau dua lub zog thiab tsis kam ua kom puas.
Hais txog dej tsis kam, PVC vinyl tawv yog ntau impermeable tshaj polyurethane. Vim qhov dej tsis kam no, PVC vinyl tawv feem ntau siv los ua cov khoom xws li nag iav, hnab nyiaj, thiab hnab tes.
Raws li kev saib xyuas, ob qho tib si polyurethane thiab PVC vinyl tawv yog yooj yim los ntxuav. Polyurethane yuav tsum tau ntxuav tsis tu ncua los tiv thaiv kev tsim cov plua plav thiab av, thaum PVC tawv tawv tuaj yeem ntxuav nrog cov ntaub ntub dej. Nrog kev saib xyuas kom zoo, ob qho tib si cov ntaub ntawv tuaj yeem siv sijhawm ntev yam tsis muaj kev qhia tseem ceeb ntawm kev hnav.
Hauv kev xaus, kev xaiv ntawm polyurethane thiab PVC vinyl tawv thaum kawg yog nyob ntawm kev npaj siv cov khoom. Yog tias ua pa yog qhov tseem ceeb, ces polyurethane yog qhov kev xaiv zoo tshaj. Ntawm qhov tod tes, yog tias yuav tsum muaj kev ruaj khov thiab dej tsis kam, ces PVC vinyl tawv yog txoj hauv kev mus. Ob qho khoom siv muaj lawv cov txiaj ntsig thiab tuaj yeem siv ntau yam kev siv, yog li nws yog nyob ntawm tus neeg siv khoom txiav txim siab seb qhov twg ua haujlwm zoo tshaj rau lawv.
