Solubility yeHPMC

Hydroxypropyl methylcellulose (HPMC) inonyungudika mumvura, inova imwe yeayo akakosha zvimiro uye inobatsira mukusiyana kwayo mukushandisa kwakasiyana. Kana yawedzerwa kumvura, HPMC inoparadzira uye hydrates, ichiita mhinduro dzakajeka uye dzakajeka. Kunyungudika kweHPMC kunoenderana nezvinhu zvakati wandei, kusanganisira dhigirii rekutsiva (DS), huremu hwepolymer, uye tembiricha yemhinduro.

Kazhinji, HPMC ine yakaderera DS kukosha inoita kunge yakanyanya kunyungudika mumvura kana ichienzaniswa neHPMC ine yakakwirira DS kukosha. Saizvozvo, HPMC ine yakaderera mamorekuru uremu mamakisi inogona kukurumidza kunyungudika mazinga kana ichienzaniswa neakakwira mamorekuru uremu mamakisi.

Kupisa kwemhinduro kunokanganisawo kunyungudika kweHPMC. Kupisa kwepamusoro kunowanzo wedzera kunyungudika kweHPMC, ichibvumira kukurumidza kupera uye hydration. Nekudaro, mhinduro dzeHPMC dzinogona kuita gelation kana kupatsanurwa kwechikamu pane tembiricha dzakakwirira, kunyanya pakakwirira.

Zvakakosha kuziva kuti nepo HPMC ichinyungudika mumvura, chiyero uye chiyero chekunyungudika chinogona kusiyana zvichienderana negiredhi chairo reHPMC, mamiriro ekugadzirisa, uye chero zvimwe zvinowedzera zviripo muhurongwa. Pamusoro pezvo, HPMC inogona kuratidza akasiyana solubility maitiro muorganic solvents kana mamwe asina-aqueous masisitimu.

iyo solubility yeHPMC mumvura inoita kuti ive yakakosha polymer kune akasiyana maapplication apo viscosity modified, firimu kuumbwa, kana zvimwe zvinoshanda zvinodiwa.
