I-HPMC hydroxypropyl methylcelluloseiye yaba yenye yezona zinto zinkulu ezinceda amayeza ekhaya nakwamanye amazwe, kuba i-HPMC inezibonelelo ezingenazo ezinye izinto ezinceda amayeza.
1. Ukunyibilika kwamanzi
Iyanyibilika emanzini abandayo angaphantsi kwama-40 ℃ okanye ama-70% e-ethanol, kwaye ayinyibiliki emanzini ashushu angaphezu kwama-60 ℃, kodwa inokunyibilika.
2. Ayisebenzi kakuhle ngokweekhemikhali
I-HPMC luhlobo lwe-non-ionic cellulose ether. Isisombululo sayo asithwali i-ionic charge kwaye asidibani neetyuwa zesinyithi okanye ii-ionic organic compounds. Ke ngoko, ezinye izinto ezincedisayo azisabelani nayo ngexesha lenkqubo yokulungiselela.
3. Uzinzo
Izinzile kwi-asidi kunye ne-alkali, kwaye ingagcinwa ixesha elide phakathi kwe-pH 3 ~ 11, kwaye i-viscosity yayo ayinatshintsho lucacileyo. Isisombululo samanzi se-HPMC sinefuthe lokulwa nokungunda kwaye sinokugcina uzinzo oluhle lwe-viscosity ngexesha lokugcina ixesha elide. Izinto ezincedisayo zamayeza zisebenzisaI-HPMCzinozinzo olungcono kunolo lusebenzisa izinto ezincedisayo zemveli (ezifana ne-dextrin, istatshi, njl.njl.).
4. Ukulungiswa kwe-viscosity
Ii-viscosity derivatives ezahlukeneyo ze-HPMC zinokuxutywa ngobuninzi obahlukeneyo, kwaye i-viscosity yayo inokutshintsha ngokomgaqo othile, kwaye inolwalamano oluhle oluhambelanayo, ngoko ke inokukhethwa ngokwemfuno. 2.5 I-Metabolic inertia I-HPMC ayifunxwa okanye ayigaywanga emzimbeni, kwaye ayiboneleli ngeekhalori, ngoko ke ingumncedi okhuselekileyo kwiimveliso zamayeza.
5. Ukhuseleko
Ngokubanzi kuthathwa njengentoI-HPMCayisiyotyhefu kwaye ayicaphukisi.
I-HPMC yodidi lweyeza yimveliso ebalulekileyo yokwenziwa kwamalungiselelo okukhululwa ahlala ixesha elide nalawulwayo. Yimveliso yamayeza exhaswa lilizwe kuphando nophuhliso, kwaye ihambelana nesikhokelo sophuhliso esixhaswa yimigaqo-nkqubo yelizwe yezoshishino. I-HPMC yodidi lweyeza yimveliso ephambili yokwenziwa kweekhaphu zezityalo ze-HPMC, ebalelwa ngaphezulu kwe-90% yezinto ezisetyenzisiweyo zeekhaphu zezityalo ze-HPMC. Iikhaphu zezityalo ezenziweyo zineengenelo zokhuseleko nococeko, ukusetyenziswa ngokubanzi, akukho mngcipheko wokusabela okudibeneyo, kunye nozinzo oluphezulu, oluhambelana nolindelo lwabathengi. Iimfuno zokhuseleko nococeko zokutya namayeza zezinye zezongezo ezibalulekileyo kunye neemveliso ezifanelekileyo zokutshintsha iikhaphu ze-gelatin zezilwanyana.
