1.Classization:
HPMC inogona kukamurwa kuita kuti inyore yemhando uye inopisa-nyauka mhando. Instant-mhando zvigadzirwa zvinopararira nekukurumidza mumvura inotonhora uye ichipinda mumvura. Panguva ino, iyo mvura haina viscosity, nekuti HPMC inongoparadzirwa mumvura uye haina kunyungudika chaiko. Mushure memaminitsi maviri, iyo viscosity yemvura zvishoma nezvishoma yakawedzera kuumba iyo inojekesa viscous colloid. Zvigadzirwa zvinopisa-zvinopera, kana uchisangana nemvura inotonhora, inogona kukurumidza kuparadzirwa mumvura inopisa uye nekunyangarika mumvura inopisa. Kana tembiricha ikadonha kune imwe tembiricha, iyo viscosity zvishoma nezvishoma inoonekwa kusvika kune yakajeka viscous colloid inoumbwa. Iyo inopisa-nyauka mhando inogona kungoshandiswa chete mune putty poda uye dhaka. Mumvura glue uye pendi, inobvisa phenomenon ichaitika uye haigone kushandiswa. Iyo Instant Type ine huwandu hwakakura hwekushandisa. Inogona kushandiswa muPutty poda uye dhaka, pamwe chete mumvura glue uye pendi, pasina kupokana.
2.Dissolution nzira:
Mvura inopisa inonyungudika Nzira mbiri dzakajairika dzinotsanangurwa seinotevera: 1), isa huwandu hunodiwa mumudziyo unopisa mvura uye kupisa kusvika pamakore makumi manomwe c. Iyo hydroxyprupyl methylcellose yakawedzerwa zvishoma nezvishoma nekukurudzira zvishoma nezvishoma, pakutanga iyo HPMC yakadzika pamusoro pemvura, uye zvishoma nezvishoma yakaumbwa slurry, iyo yakatonhorera nekukurudzira. 2. Wobva wawedzera iyo yakasara huwandu hwemvura inotonhora kumvura inopisa mune iyo slurry, musanganiswa wacho wakatonhorera mushure mekukurudzira.
Powder kusanganisa nzira: Sanganisa HPMC Powder neine huwandu hweimwe zvinhu zvePowders, sanganisaiwo mimwe nguva yekunyungunuka, - Iyi nzira inoshandiswa nePutty poda uye vagadziri vemota. [Hydroxyprenyl methylcellose (HPMC) inoshandiswa seanotsigira uye kumuka kwemvura mumiririri muPutty PoWder Dorar]
