Zithunzi za PVC
Kubalalika: Wabwino kuyimitsidwa kubalalitsidwa ntchito, ndi kusintha mavuto padziko ndi ndende, monoma adzakhala omwazika mu particles zabwino. Kuyimitsidwa: kusintha utomoni matenthedwe bata ndi kulamulira tinthu kukula kugawa, kusintha tinthu mawonekedwe ndi mamasukidwe akayendedwe kugawa, kuchepetsa zochitika za fisheye. Adsorbability: kupititsa patsogolo utomoni ndi zinthu kukonzedwa, kuti PVC utomoni kutulutsa kanthu, kumapangitsanso mayamwidwe plasticizer.
PVC polymerization dongosolo anakonza ndi mkulu khalidwe HPMC, kuwonjezera kuonetsetsa kuti ntchito akukumana mfundo za mayiko, komanso ali ndi makhalidwe abwino zikuoneka thupi, katundu tinthu zabwino kwambiri Sungunulani rheological khalidwe. Mu pawiri dispersant dongosolo, polyvinyl mowa (PVA) ndi madigiri osiyana alcoholysis ndi polymerization ndi hydroxypropyl methylcellulose (HPMC) pawiri collocation ndi bwino, amene amathandiza kuti porosity utomoni, ndi mayamwidwe plasticizer kumathandizanso.
