Iyini i-viscosity ye-HPMC E5?

I-HPMC E5 iyi-low-molecular-weight hydroxypropyl methylcellulose (HPMC) esetshenziswa njenge-ejenti ejiyayo, elengayo, kanye ne-emulsifying emikhiqizweni eyahlukene. Kuyimpushana emhlophe, engenaphunga, enganambitheki encibilika emanzini abandayo futhi engancibiliki emanzini ashisayo. Isetshenziswa ezintweni ezahlukahlukene, kufaka phakathi ukudla, imithi, kanye nezimonyo.

I-viscosity ye-HPMC E5 ivamise ukukalwa nge-centipoise (cP). Lesi isilinganiso sokumelana koketshezi ukuze lugeleze, futhi sivezwa njengenani lokucindezela elidingekayo ukuze kuhanjiswe umthamo onikeziwe woketshezi ngesivinini esithile. I-viscosity ye-HPMC E5 ingaba kusuka ku-4 kuya ku-6 cP, kuye ngokugxila kwesixazululo kanye nezinga lokushisa.

Ekuhlanganiseni okungu-1%, i-viscosity ye-HPMC E5 ivamise ukuba ngu-5 cP. Ekuhlanganisweni kuka-2%, i-viscosity iyanda cishe ku-5 cP. Ekuhlanganisweni kwe-3%, i-viscosity iyanda cishe ku-5 cP. Ekuhlanganiseni okungu-4%, i-viscosity iyanda ibe cishe ku-5 cP.

Kafushane, i-viscosity ye-HPMC E5 ingasukela ku-1 kuye ku-100,000 cP, kuye ngokugxila kwesixazululo, izinga lokushisa, kanye ne-pH. Ekuhlanganiseni okungu-1%, i-viscosity ivamise ukuba ngu-5 cP. Emazingeni aphezulu, i-viscosity iyanda, futhi emazingeni okushisa aphezulu kanye namazinga aphezulu e-pH, i-viscosity nayo iyanda.
