IHydroxypropyl methylcellulose HPMC ingathuthukisa kakhulu ukugcinwa kwamanzi odaka.Uma inani elingeziwe lingu-0.02%, izinga lokugcinwa kwamanzi lizokwenyuka lisuka ku-83% liye ku-88%;inani elingeziwe ngu-0.2 %, izinga lokugcinwa kwamanzi lingama-97%.Ngesikhathi esifanayo, inani elincane le-HPMC libuye linciphise ngokuphawulekayo izinga lokuhlukaniswa kanye nokopha kodaka, okubonisa ukuthi i-HPMC ayikwazi nje ukuthuthukisa ukugcinwa kwamanzi odaka, kodwa futhi ithuthukisa kakhulu ukuhlangana kodaka, okuyinto kakhulu. kuzuzisa ukufana kwekhwalithi yokwakha udaka.
Nokho, i-hydroxypropyl methylcellulose HPMC inomthelela othile omubi emandleni aguquguqukayo namandla okucindezela odaka.Ngokukhula kwenani elingeziwe le-HPMC, amandla okuguquguquka kanye namandla okucindezela odaka kancane kancane ancipha.Ngesikhathi esifanayo, i-HPMC ingakhuphula amandla okuqina odaka.Uma inani le-HPMC lingaphansi kuka-0.1%, amandla okuqina odaka akhuphuka ngokunyuka komthamo we-HPMC.Uma inani lidlula u-0.1%, amandla okuqina ngeke anyuke kakhulu.IHydroxypropyl Methyl
I-Cellulose HPMC iphinde ikhulise amandla ebhondi odaka.I-HPMC engu-0.2% inyuse amandla ebhondi yodaka isuka ku-0.72 MPa yaya ku-1.16 MPa.
Ucwaningo luye lwabonisa ukuthi i-HPMC inganweba kakhulu isikhathi sokuvulwa kodaka, ukuze inani lokuwa kwedaka lincishiswe kakhulu, okuzuzisa kakhulu ukwakhiwa kwe-tile bonding.Uma i-HPMC ingahlanganisiwe, amandla ebhondi yodaka ancipha esuka ku-0.72 MPa aya ku-0.54 MPa ngemva kwemizuzu engu-20, futhi amandla ebhondi odaka ngo-0.05% kanye no-0.1% we-HPMC azoba ngu-0.8 MPa kanye no-0.84 MPa ngemva kwemizuzu engu-20.Uma i-HPMC ingahlanganisiwe, ukushelela kodaka ngu-5.5mm.Ngokukhula kokuqukethwe kwe-HPMC, ukushelela kuzokwehla ngokuqhubekayo.Uma umthamo ungu-0.2%, ukushelela kodaka kuyehla kube ngu-2.1mm.
