1. Hydroxypropyl methyl celluloseKana mvura inopisa yakanyungudika mumvura inotonhora, inosangana nematambudziko. Asi tembiricha yayo ye gelation mumvura inopisa yakakwira zvakanyanya kupfuura yemethyl cellulose. Kunyungudika kwemethyl cellulose mumvura inotonhora kwavandudzikawo zvikuru.
2. Kuwanda kwehydroxypropyl methyl cellulose kwakabatana nehuremu hwayo hwemamorekuru, uye huremu hukuru hwemamorekuru ndihwo hunonyanya kusimba. Kupisa kuchakanganisawo kusimba kwayo, tembiricha inowedzera, kusimba kunoderera. Zvisinei, kusimba kwekupisa kwakanyanya kwakaderera pane kwemethyl cellulose. Mhinduro yacho inogara yakagadzikana kana yakachengetwa patembiricha yemumba.
3. Hydroxypropyl methyl cellulose inogara yakasimba kune acid nealkali, uye mvura yayo inogadzikana zvakanyanya muhuwandu hwe pH = 2 ~ 12. Caustic soda nemvura ye lime hazvina zvazvinoita pahunhu hwayo, asi alkali inogona kukurumidzisa kunyungudika kwayo uye kuwedzera viscosity yepini. Hydroxypropyl methyl cellulose inogara yakasimba kune general salts, asi kana huwandu hwemunyu hwakwira, viscosity ye hydroxypropyl methyl cellulose solution inowanzo kuwedzera.
4. Kuchengetwa kwemvura kwehydroxypropyl methyl cellulose kunoenderana nehuwandu hwayo hwekuwedzera, viscosity, nezvimwewo. Mwero wekuchengetedza mvura pasi pehuwandu hwakafanana hwekuwedzera wakakwira kupfuura wemethyl cellulose.
5. Kunamira kwehydroxypropyl methyl cellulose kumortar kwakakwira kupfuura kwemethyl cellulose.
6. Hydroxypropyl methyl celluloseine simba rekudzivirira ma enzymes kupfuura methyl cellulose, uye mukana wekuti enzyme iparare mumushonga wakaderera pane methyl cellulose.
