Lihlahisoa tsa Hydroxypropyl Methyl Cellulose li na le tšebeliso e phahameng haholo sebakeng sa ho emisoa ha polymerization ea vinyl chloride Chaena.Ka ho emisoa ha polymerization ea vinyl chloride, sistimi e hasantsoeng e na le tšusumetso e tobileng ho sehlahisoa, resin ea PVC, le boleng ba ts'ebetso ea eona le lihlahisoa.HydroxypropylMethylCellulose e thusa ho ntlafatsa botsitso ba mocheso oa resin le ho laola kabo ea boholo ba likaroloana..Resin ea PVC e entsoeng ka boleng bo phahameng ba HydroxypropylMethylCellulose ha e khone feela ho netefatsa mohala oa ts'ebetso le litekanyetso tsa machaba, empa hape e ka ba le thepa e ntle e bonahalang ea 'mele, thepa e babatsehang ea likaroloana le boitšoaro bo botle ba ho qhibiliha ha rheological.
Tlhahisong ea li-resin tsa maiketsetso, joalo ka polyvinyl chloride, polyvinylidene chloride, le copolymers tse ling, suspension polymerization ke eona e sebelisoang haholo mme e tlameha ho ba monomers e sa fetoheng ea hydrophobic e emisitsoeng ka metsing.Joaloka li-polymers tse qhibilihang ka metsi, sehlahisoa sa HydroxypropylMethylCellulose se na le ts'ebetso e ntle ea holim'a metsi 'me e sebetsa e le li-colloidal agents tse sireletsang.HydroxypropylMethylCellulosecan e thibela ka katleho likaroloana tsa polymeric ho hlahisa le ho kopanya.Ho feta moo, leha HydroxypropylMethylCelluloseis e le polymer e qhibilihang ka metsing, e ka qhibiliha hanyane ka har'a li-monomers tsa hydrophobic mme e ka eketsa porosity ea monomer bakeng sa tlhahiso ea likaroloana tsa polymeric.
Ho phaella moo, liphuputso li bontšitse hore ts'ebetsong ea tlhahiso ea PVC, likhoebo tse fapaneng li sebelisa mokhoa o fapaneng oa ho qhalakanngoa, kahoo thepa ea ho roala ka ntle ea PVC e hlahisoang le eona e fapane, kahoo HydroxypropylMethylCellulose e ka ama ts'ebetso ea ts'ebetso ea li-resin tsa PVC.Lenaneong la li-agent tse arolang, resin ea PVC e emisitsoeng e lokiselitsoeng ho tloha ho motsoako o qhalakanyang oa polyvinyl alcohol (PVA) e nang le li-alcohol le li-degree tsa polymerization le hydroxypropyl methyl cellulose (HPMC) e ka ba le liphello tse fapaneng mosebetsing oa ho sebetsa.Liteko li bontšitse hore motsoako oa HydroxypropylMethylCellulose le KP-08 / KZ-04 le tekanyo ea alcoholysis ea 68% -75% e molemo hape e molemo bakeng sa porosity ea resin le ho kenngoa ha li-plasticizers.
