Hydroxypropyl methylcellulose (HPMC) yave chinhu chinowanzo shandiswa mumidziyo yekuwachira nekuda kwekukora kwayo, kuchengetedza mvura uye emulsifying zvivakwa. HPMC inogadzirwa kubva kune cellulose, yakasikwa polima inowanikwa muzvirimwa. HPMC i polymer inonyungudika nemvura ine zvakasiyana-siyana zvekushandisa muindasitiri nekugadzira. Mukuwachisa mbatya, HPMC inoshandiswa kusimudzira kuita kwese kwekuchenesa kwechigadzirwa.
HPMC chinhu chinonyungudika zvakanyanya. Kunyungudika kweHPMC kunoenderana nezvinhu zvakati wandei, kusanganisira huremu hwayo hwemamorekuru, dhigirii rekutsiva, uye tembiricha. Kazhinji, HPMC inoratidza kunyungudika kwakanyanya mumvura uye polar solvents. HPMC ine huremu hwemamorekuru hwe10,000 kusvika 1,000,000 Da uye kazhinji ine kunyungudika mumvura kwe1% kusvika 5%, zvichienderana negiredhi uye kuisa pfungwa. Kunyungudika kweHPMC mumvura kunokanganiswa nezvinhu zvakasiyana-siyana senge pH, tembiricha uye kutarisisa.
Muma detergents, HPMC ine yakakwira solubility zvinodiwa inofanira kushandiswa kuve nechokwadi chekunyungudika kwe detergent mumvura. Kunyungudika kweHPMC mumidziyo yekuwachira kunokanganisa zvinhu zvakati wandei, zvinosanganisira kuvepo kwezvimwe zvinhu, tembiricha yekugezesa uye kuoma kwemvura. Kuoma kwemvura kunokanganisa kunyungudika kweHPMC nekuti kuwanda kwezvicherwa zvakanyungudutswa, senge calcium nemagnesium, zvinokanganisa kunyungudika kweHPMC mumvura.
Izvo zvakakosha kuti usarudze iyo yakakodzera HPMC giredhi ine yakakwira solubility zvinodiwa uye kugona kutsungirira yakaoma washing mamiriro. HPMC mamakisi ane yakakwira solubility zvinodiwa anokurudzirwa zvekugezesa mbatya kuti ive nechokwadi chekuti chigadzirwa chinonyungudika mumvura uye chinopa kuita kwekuchenesa kunoenderana. Kushandisa HPMC ine yakaderera solubility zvinodiwa zvinogona kuita kuti detergent iwande uye iwedzere mumvura, ichideredza kushanda kwechigadzirwa.
Kunyungudika kweHPMC kwakakosha pakushandisa kwayo mumhando dzakasiyana dzekushandisa, kusanganisira yekuwachira. Kunyungudika kweHPMC mumvura kunokanganiswa nezvinhu zvakati wandei, zvinosanganisira pH, tembiricha, uye kuisa pfungwa. Mune zvekugezesa mbatya, HPMC ine yakakwira solubility zvinodiwa inofanira kushandiswa kuve nechokwadi chekunyungudika kwechigadzirwa mumvura. Kushandisa HPMC ine yakaderera solubility zvinodiwa zvinogona kuita kuti detergent iwande nekunaya, ichideredza kushanda kwechigadzirwa. Naizvozvo, zvinodikanwa kuti usarudze akakodzera HPMC mamakisi ane yakakwira solubility zvinodiwa zvekugeza mbatya kuti uve nechokwadi chekuchenesa kunoenderana.
