Hauv cov ntawv thov sib khi ua ke, kev xaiv ntawm PVC (polyvinyl chloride) cov khoom siv nplaum ncaj qha cuam tshuam nrog cov nyiaj sib xyaw ua lub zog, kav ntev, thiab muaj feem xyuam thaiv cov xwm txheej. Vim yog qhov xam tau tsawg polarity thiab siab saum lub zog ntawm PVC, dog nplaum tawm tsam kom ua tiav kom ua tiav cov nyiaj txhiv muaj zog. Yog li ntawd, cov khoom nplaum yuav tsum ua tib zoo xaiv raws cov kev xav tau tshwj xeeb.
1. Cov khoom siv hauv PVC kua nplaum
Tam sim no, mainstream PVC cov nplaum tau faib rau hauv peb lub ntsiab: daws - polyurethane-. Hnyav - Basedives, raws li cov kuab tshuaj organic thiab cycloform thiab cycloform thiab cycloform thiab cycloform thiab cycloform thiab cyclohot phab ntsa pvc los ua ib qho kev sib txuam ntawm cov ntawv cog lus. Lawv tsim nyog rau kev sib raug zoo ntawm cov kav dej thaiv kom nruj Acrylate {{{}}} Raws cov nplaum kho kom huv ntawm cov tshuaj tiv thaiv polymerization ntawm cov kev hloov pauv siab, muab ob qho tib si yoog thiab huab cua tsis kam. Lawv yog tshwj xeeb zoo -}} haum rau kev sib raug zoo- tiv taus profiles. Hloov polyurethane cov nplaum nplaum, nrog lawv cov dej tsis taus thiab elasticity tsis zoo thiab elasticity, excel nyob rau hauv cov chaw noo noo los yog nyob rau hauv lub zog ruaj khov.
2. Cov kev txiav txim siab tseem ceeb rau cov khoom xaiv
Ua ntej, nws yog qhov tseem ceeb los txiav txim hom ntawm pvc tau sib raug zoo. Rau cov muag muag muag pvc, yas minizer tsiv teb tuaj yeem ua rau cov tshuaj nplaum, yog li cov yas ua kom yooj yim- ionistant mis yog nyiam. Thib ob, cov xwm txheej ib puag ncig (xws li UV kis tau kub thiab UV kis tau) Yuav tsum muaj cov nplaum kom haum (feem ntau ntau dua lossis sib npaug rau 80 degree) thiab yellaging tsis kam. Txog cov ntawv thov zaub mov noj, tsis - cov khoom siv toxic uas tau raws FDA lossis LFGB cov qauv yuav tsum raug xaiv. Tsis tas li ntawd, cov qauv kev thov (xws li txhuam hniav lossis tshuaj tsuag) kuj cuam tshuam cov khoom siv viscosity. Tsawg {{{{}}} Voscosity nplaum muaj txiaj ntsig zoo dua hauv kev nkag siab ntau qhov khoob.
3. Cov lus pom zoo tswv yim thiab qauv ntsuas pom
Cov neeg siv tau raug qhia kom kuaj xyuas qhov ua piv txwv ua piv txwv los ntawm kev sim me me, tsom mus rau thawj zaug muaj zog thiab ntev {}} sij} lub sij hawm tsis kam. Nrog cov kev cai tswj ib puag ncig ib puag ncig ib puag ncig, kev txhim kho dej {}} bio {{}} based resins yuav dhau los ua ke. Thaum txo cov pa hluav taws xob, cov hau kev no yuav tsum sib npaug kev ua tau zoo thiab raug nqi- ua hauj lwm zoo. Xaiv cov ntaub ntawv zoo tsis tsuas yog txhim kho cov khoom lag luam zoo tab sis kuj tseem txuas ntxiv lub neej nyob hauv PVC bonding daim ntawv thov.
