Ko nga hua Hydroxypropyl Methyl Cellulose te nui o te kai i roto i te waahi o te polymerization whakatārewatanga o te vinyl chloride i Haina.I roto i te polymerization whakatārewatanga o te vinyl pūhaumāota, te pūnaha marara he pānga tika i runga i te hua, PVC resin, me te ki runga ki te kounga o ona tukatuka me ngā hua.Ka awhina a HydroxypropylMethylCellulose ki te whakapai ake i te pumau o te waiariki o te kapia me te whakahaere i te tohatoha rahi matūriki.Ko te kapia PVC i hangaia mai i te HydroxypropylMethylCellulose o te kounga teitei e kore e taea anake te whakarite i te raina mahi me nga paerewa o te ao, engari ka taea hoki te whai i nga ahuatanga o te tinana, nga ahuatanga matūriki pai me te pai o te whanonga rheological rewa.
I roto i te hanga kapia waihanga, penei i te polyvinyl chloride, polyvinylidene chloride, me etahi atu copolymers, ko te polymerization whakatārewa te mea tino whakamahia, me he monomers hydrophobic invariant kua whakatarewa ki te wai.Hei polymers wairewa-wai, HydroxypropylMethylCellulose hua he mahi mata pai, me te mahi hei apiha colloidal tiaki.Ka taea e HydroxypropylMethylCellulose te aukati i nga matūriki polymeric mai i te whakaputa me te whakahiato.I tua atu, ahakoa ko te HydroxypropylMethylCellulose he polymer wairewa wai, ka taea te rewa paku i roto i nga monomers hydrophobic me te whakanui ake i te porosity monomer mo te hanga matūriki polymeric.
I tua atu, kua whakaatuhia e nga rangahau i roto i te mahinga o te PVC, he rereke nga hinonga rereke e whakamahi ana i nga punaha marara rereke, na reira he rereke nga ahuatanga o waho o te PVC i hangaia, na reira ka taea e te HydroxypropylMethylCellulose te pa ki te mahi tukatuka o te PVC resins.I roto i te punaha marara whakahiato, he rereke pea nga paanga o te kapia PVC whakatārewatanga mai i te matara whakahiato o te waipiro polyvinyl (PVA) he rereke te waipiro me te tohu polymerization me te hydroxypropyl methyl cellulose (HPMC) he rereke nga paanga ki te mahi tukatuka.Kua whakaatuhia e nga whakamatautau he pai ake te kohinga o te HydroxypropylMethylCellulose me te KP-08/KZ-04 me te tohu waipiro o te 68% -75% he pai ake, he pai hoki mo te porosity o te kapia me te whakaurunga o te kirihou.
