Kugona kuchengetedza mvura kwehydroxypropyl methylcellulose kunoenderana neiyo hydroxypropyl yemukati.Pasi pemamiriro akafanana, simba rekuchengetedza mvura repamusoro hydroxypropyl methylcellulose yakasimba, uye methoxy yemukati yeiyo hydroxypropyl yemukati inoderedzwa zvakakodzera..Iyo yakakwirira yemukati yehydroxypropyl methylcellulose, iyo yakakura viscosity yayo, saka kana uchisarudza chigadzirwa, iwe unofanirwa kusarudza chigadzirwa chinokodzera iwe zvinoenderana nechinangwa chechigadzirwa.
Tembiricha uye zvimwe zvinhu zvine chekuita nekuchengetwa kwemvura kwehydroxypropyl methylcellulose.
Thermal gel tembiricha:
Cellulose ether HPMC ine high thermal gelation tembiricha uye zvakanaka kuchengetedza mvura;pane zvinopesana, ine hurombo hwekuchengetedza mvura.
Viscosity ye cellulose ether HPMC:
Kana iyo viscosity yeHPMC inowedzera, kuchengetwa kwayo kwemvura kunowedzerawo;apo viscosity inowedzera kune imwe nhanho, kuwedzera kwekuchengetedza mvura kunoderera.
Cellulose ether HPMC homogeneous:
HPMC ine maitiro akafanana, yunifomu yekugovera methoxyl uye hydroxypropoxyl, uye ine mvura yakanaka yekuchengetedza.
Cellulose ether HPMC chipimo chemushonga:
Kuwanda kwedosi, kunowedzera chiyero chekuchengetedza mvura uye zvakanyanya kujeka mhedzisiro yekuchengeta mvura.
Kana huwandu hwekuwedzera huri 0.25 ~ 0.6%, chiyero chekuchengetedza mvura chinowedzera nokukurumidza nekuwedzera kwekuwedzera kwekuwedzera;apo huwandu hwekuwedzera hunowedzera kuwedzera, kuwedzera kwemaitiro ekuchengetwa kwemvura kunononoka.
Muchidimbu, kuchengetwa kwemvura kweHPMC kwakabatana nezvinhu zvakadai sekushisa uye viscosity, uye kuchengetwa kwayo kwemvura kwakabatana nehuwandu hwehydroxypropyl methylcellulose yakawedzerwa.Kana huwandu hwehydroxypropyl methylcellulose hwasvika kune imwe kukosha, kuita kwayo kwekuchengetedza mvura kunosvika pachiyero.
