Ukusetyenziswa ngokubanzi kweHydroxypropyl Methyl Cellulose

IHydroxypropyl methyl cellulose, ekubhekiselwa kuyo njenge (HPMC): ihydroxypropyl methyl cellulose (HPMC) ayivumba, ayinancasa, ayinatyhefu, kukho iindidi ezimbini zomgubo okhawulezayo nongaphazamisiyo, ngoko nangoko, Xa udityaniswa namanzi abandayo, ukhawuleza. iyahlakazeka kwaye iphele emanzini. Ngeli xesha, i-liquid ayinayo i-viscosity. Emva kwemizuzu emi-2, i-viscosity ye-liquid iyanda, yenza i-colloid ebonakalayo ebonakalayo. Uhlobo olungekho ngoko nangoko: Inokusetyenziswa kuphela kwiimveliso zomgubo owomileyo ezifana nomgubo weputty kunye nodaka lwesamente. Ayinakusetyenziswa kwiglue yolwelo kunye nepeyinti, kwaye kuya kubakho i-clumping.
