Hydroxypropyl methyl cellulose (HPMC) isiri-ionic cellulose ether inowanikwa ne cellulose alkalization, etherification, neutralization uye kugeza.HPMC ine good thickening, dispersing, emulsifying, film-forming properties, etc. Ndiyo yekutanga sarudzo yekugadzirwa kwemhando yepamusoro yekuvaka zvinhu additives.Muzvinhu zvekuvaka, huwandu hwekuwedzera hweHPMC hwakaderera kwazvo, chete 0.1% -1%, asi inoita basa risingadzoreki uye inogona kuvandudza zvakanyanya kuchengetwa kwemvura, fluidity uye lubricity yezvivakwa zvekuvaka.Zvivakwa zvekuvaka zvakawedzerwa neHPMC zviri nyore kusanganisa uye kushandisa, kuvandudza kushanda kwevashandi vekuvaka, kuwedzera nguva yakavhurika, kunatsiridza kusimba kwechisungo, uye kugadzira yakatsetseka uye yakapfava yekupotera.
