I-Hydroxypropyl methylcellulose (HPMC)yipolymer eguquguqukayo esetyenziswa kakhulu kwiintlobo ngeentlobo zezicelo, kuquka amayeza, iimveliso zokutya, izinto zokuthambisa, kunye nokusetyenziswa kwemizi-mveliso. Umgangatho we-HPMC unokwahluka ngokuxhomekeke kwizinto ezifana nobunzima be-molecular, i-viscosity, i-degree of substitution (DS), kunye nobunyulu, obuchaphazela ngokuthe ngqo ukusebenza kwayo kwiizicelo ezithile.
Izinto Eziphambili Ezichaphazela Umgangatho weHydroxypropyl Methylcellulose
Ubunzima beMolekyuli
Ubunzima bemolekyuli (MW) bubhekisa kubungakanani bemolekyuli ye-AnxinCel®HPMC kwaye budlala indima ebalulekileyo ekumiseleni ubungqindilili bayo kunye nokunyibilika kwayo. Ubunzima bemolekyuli obuphezulu be-HPMC budla ngokuba ne-viscosity ephezulu, eluncedo kwizicelo ezifana nokukhululwa kwamayeza okanye njenge-arhente yokutyeba kwiifomyula ezahlukeneyo.
