Nezve dambudziko rekushisa kwegel reHydroxypropyl Methyl Cellulose HPMC, vashandisi vazhinji havawanzo kuterera kune dambudziko rekushisa kwegel yeHydroxypropyl Methyl Cellulose. Mazuva ano, Hydroxypropyl Methyl Cellulose inowanzosiyaniswa maererano ne viscosity yayo, asi kune dzimwe nzvimbo dzakakosha uye maindasitiri akakosha, hazvina kukwana kungoratidza viscosity yechigadzirwa. Izvi zvinotevera zvinosuma muchidimbu tembiricha yegel yeHydroxypropyl Methyl Cellulose.
Huwandu hweboka reMethoxyl hwakanangana nechiyero che cellulose sourization, uye zvirimo muboka reMethoxyl zvinogona kugadziridzwa nekudzora fomula, kuita tembiricha uye nguva yekuita. Panguva imwecheteyo, dhigirii rekusashanda rinokanganisa dhigirii rekutsiva Hydroxyethyl kana Hydroxypropyl. Nokudaro, kuchengetwa kwemvura ye cellulose ether ine high gel tembiricha ichave yakashata. Iyi nzira yekugadzira inoda kuongororwa, saka haisi iyo mari yekugadzira cellulose ether yakaderera kana Methoxy content yakaderera, pane zvinopesana, mutengo uchave wakakwirira.
Iyo tembiricha yegel inotarwa nemapoka emethoxyl, uye kuchengetwa kwemvura kunotemwa nemapoka eHydroxypropoxy. Pane mapoka matatu chete anotsiviwa pa cellulose. Tsvaga tembiricha yako yekushandisa yakakodzera, kuchengetwa kwemvura kwakakodzera, uye wobva waona modhi yeiyi cellulose.
Iyo tembiricha yegel chinhu chakakosha pakushandiswa kwecellulose ether. Kana tembiricha yepakati ikapfuura tembiricha yegel, cellulose ether inoparadzaniswa kubva mumvura uye inorasikirwa nekuchengetedza kwayo mvura. Iyo tembiricha yegel ye cellulose ether pamusika inogona kuzadzisa zvinodiwa zvenzvimbo yekushandisa dhaka (kunze kwenzvimbo dzakakosha). Ini pachangu ndinofunga kuti hazvifanirwe kutarisisa zvakanyanya kune iyo performance index ye gel tembiricha paunenge uchiisa dhaka. Zvechokwadi, kugadzirwa kwe cellulose ether Vagadziri vanofanira kufunga nezvazvo.
