Mtengo wa HPMC F50

EipponCell HPMC F 50 ndi dispersant kwambiri ntchito polyvinyl kolorayidi (PVC) makampani.Pa kuyimitsidwa polymerization wa vinilu kolorayidi, amachita ntchito zingapo.Choyamba, amachepetsa kukangana interfacial pakati vinilu kolorayidi monoma (VCM) ndi madzi, atsogolere yunifolomu ndi khola kubalalitsidwa kwa VCM mu sing'anga amadzimadzi.Kachiwiri, zimalepheretsa kuphatikizika kwa madontho a VCM pagawo loyambirira la polymerization.Potsirizira pake, izo zimalepheretsa coalescence pakati polima particles wapakatikati ndi kenako magawo ndondomeko.Mu kuyimitsidwa kwa polymerization system, EipponCell HPMC F 50 imagwira ntchito ziwiri zobalalitsa VCM ndikuwonetsetsa bata.

Utoto wa polyvinyl chloride (PVC) wokhala ndi polymerization wocheperako nthawi zambiri umatanthawuza utomoni wa PVC wokhala ndi digiri ya polymerization pansi pa 800. Mtundu uwu wa utomoni, chifukwa cha kulemera kwake kwa maselo, kachulukidwe kake, kusungunuka kwamadzimadzi, kusungunuka kwamadzimadzi, nthawi yochepa ya plasticizing, ndi kumasuka. pokonza, amapeza ntchito zambiri pakupanga mapepala, zopangira ma jekeseni, kuumba nkhonya, ndi kupanga utomoni wosinthidwa (monga chlorinated polyvinyl chloride kudzera mwakuya chlorine wa vinyl chloride resin), pakati pa ena.Komabe, utomoni wa PVC wokhala ndi digiri yochepa ya polymerization umasonyeza kutsika kochepa komanso tinthu tating'onoting'ono ta utomoni.Tinthu filimu yopangidwa ndi kumezanitsa copolymerization wa dispersants ndi vinilu kolorayidi amakhala ndi wandiweyani, zomwe zingakhudze ntchito utomoni processing ndi kusinthidwa wotsatira.
