Vazhinji vashandisi havawanzo kutarisisa kune dambudziko rekushisa kwegel kwehydroxypropyl methylcellulose.Mazuva ano, hydroxypropyl methylcellulose inowanzosiyaniswa maererano ne viscosity, asi kune dzimwe nzvimbo dzakakosha uye maindasitiri akakosha, chete viscosity yechigadzirwa inoratidzwa.Hazvina kukwana, zvinotevera zvinosuma muchidimbu tembiricha yegel yehydroxypropyl methylcellulose.
Zvinyorwa zvemethyl acid zvakanangana ne ester-forming degree ye cellulose ester, uye zviri mukati memethyl acid inogadziriswa kudzora kuumbwa, kuita tembiricha uye nguva yekuita.Panguva imwecheteyo, chiyero che ether solution chinokanganisa zvinyorwa zve hydroxyethyl kana hydroxyapatite.Naizvozvo, cellulose ethers pamatembiricha akakwirisa ejeri anozonyorova.Iyi nzira yekugadzira inofanirwa kuve inobatika, saka pane yakaderera mwero methoxides, cellulose ethers ichave yakakwira zvishoma mumutengo.
Gel tembiricha yakatemwa ne methoxide uye hydroxyproazepam ine hydroxyproxin.Mapoka matatu chete anogona kutsiviwa pa cellulose.Tsvaga tembiricha yakakodzera, chengetedza humidity, uye sarudza iyo pulp pateni.Kupisa kwejeri ndiyo nzvimbo yakakosha yekushandiswa kwe cellulose ether.Kana tembiricha yepakati ikapfuura tembiricha yegel, cellulose ether inoburitswa kubva mumvura.Kupisa kwehuputi pamusika kunonyanya kusangana nezvinodiwa zvekugadzirisa munharaunda (kunze kwemamiriro ezvinhu anokosha).Zvinotendwa kuti paunenge uchishandisa mhinduro, hazvidikanwi kubhadhara zvakanyanya kune zviratidzo zvekushanda paunenge uchishandisa gel.Zvechokwadi, mugadziri we cellulose ether anofanira kuitora iyo chiratidzo ichi.
