Hydroxypropyl Methyl Cellulose mankhwala ndi mowa pazipita m'dera kuyimitsidwa polymerization wa vinilu kolorayidi ku China.Mu kuyimitsidwa polymerization wa vinilu kolorayidi, ndi omwazika dongosolo zimakhudza mwachindunji mankhwala, PVC utomoni, ndi pa khalidwe la processing ndi mankhwala.HydroxypropylMethylCellulose imathandizira kukhazikika kwamafuta a utomoni ndikuwongolera kugawa kwa tinthu..PVC utomoni wopangidwa kuchokera apamwamba HydroxypropylMethylCellulose osati kuonetsetsa mzere ntchito ndi mfundo za mayiko, komanso akhoza kukhala ndi makhalidwe abwino zooneka thupi, kwambiri tinthu katundu ndi khalidwe kusungunuka bwino rheological.
Popanga utomoni wopangira, monga polyvinyl chloride, polyvinylidene chloride, ndi ma copolymers ena, kuyimitsidwa ma polymerization ndikomwe amagwiritsidwa ntchito kwambiri ndipo kuyenera kukhala kosasintha kwa hydrophobic monomers kuyimitsidwa m'madzi.Monga ma polima osungunuka m'madzi, mankhwala a HydroxypropylMethylCellulose ali ndi ntchito yabwino kwambiri komanso amagwira ntchito ngati zoteteza ma colloidal agents.HydroxypropylMethylCellulosecan bwino kuteteza polymeric particles kupanga ndi agglomeration.Komanso, ngakhale HydroxypropylMethylCelluloseis madzi sungunuka polima, akhoza pang'ono sungunuka mu monomers hydrophobic ndi kuonjezera monomer porosity kupanga polymeric particles.
Kuphatikiza apo, kafukufuku wasonyeza kuti popanga PVC, mabizinesi osiyanasiyana amagwiritsa ntchito machitidwe obalalika osiyanasiyana, kotero kuti mawonekedwe akunja a PVC opangidwa ndi osiyana, motero HydroxypropylMethylCellulose imatha kukhudza magwiridwe antchito a utomoni wa PVC.Mu gulu dispersing wothandizila dongosolo, kuyimitsidwa PVC utomoni wokonzedwa kuchokera gulu dispersing wothandizila wa polyvinyl mowa (PVA) ndi madigiri osiyana alcoholysis ndi polymerization ndi hydroxypropyl methyl cellulose (HPMC) angakhale ndi zotsatira zosiyana pa processing ntchito.Mayeso asonyeza kuti pawiri wa HydroxypropylMethylCellulose ndi KP-08/KZ-04 ndi digiri alcoholysis 68% -75% ndi bwino komanso kopindulitsa kwa porosity utomoni ndi mayamwidwe plasticizers.
