Kugona kwehydroxypropyl methylcellulose kuchengetedza mvura kunoenderana nehuwandu hwehydroxypropyl. Mumamiriro ezvinhu akafanana, kugona kwehydroxypropyl methylcellulose yakawanda kuchengetedza mvura kwakasimba, uye huwandu hwemethoxy hwehuwandu hwehydroxypropyl hwakafanana hunoderedzwa zvakakodzera. . Kana huwandu hwehydroxypropyl methylcellulose hwakakwira, viscosity yayo inowedzera, saka pakusarudza chigadzirwa, unofanirwa kusarudza chigadzirwa chinokunakira zvichienderana nechinangwa chechigadzirwa.
Kupisa nezvimwe zvinhu zvine chekuita nekuchengetwa kwemvura kwehydroxypropyl methylcellulose.
Kupisa kwegel rinopisa:
Cellulose ether HPMC ine tembiricha yepamusoro yekupisa uye inochengetedza mvura zvakanaka; pane kudaro, haina mvura yakawanda.
Kupenya kwe cellulose ether HPMC:
Kana viscosity yeHPMC ikawedzera, kuchengetedza kwayo mvura kunowedzerawo; kana viscosity ikawedzera kusvika pamwero wakati, kuwedzera kwekuchengetwa kwemvura kunoderera.
Cellulose ether HPMC yakafanana:
HPMC ine maitiro akafanana, kupararira kwemethoxyl nehydroxypropoxyl zvakaenzana, uye ine mvura inochengetwa zvakanaka.
Chiyero che HPMC che cellulose ether:
Kana mushonga wacho wakawanda, mwero wekuchengetedza mvura unowedzera uye mhedzisiro yekuchengetedza mvura iri pachena.
Kana huwandu hwekuwedzera huri 0.25 ~ 0.6%, mwero wekuchengetedza mvura unowedzera nekukurumidza nekuwedzera kwehuwandu hwekuwedzera; kana huwandu hwekuwedzera huchiwedzera, mwero wekuwedzera kwehuwandu hwekuchengetedza mvura unoderera.
Muchidimbu, kuchengetwa kwemvura kweHPMC kwakabatana nezvinhu zvakaita sekupisa uye kusviba, uye kuchengetwa kwemvura kwayo kwakabatana nehuwandu hwehydroxypropyl methylcellulose inowedzerwa. Kana huwandu hwehydroxypropyl methylcellulose hwasvika pahunhu hwakati, mashandiro ayo ekuchengetedza mvura anosvika pakuenzana.
