Hydroxypropyl methylcellulose (HPMC) maitiro

Chigadzirwa chinosanganisa akawanda emuviri nemakemikari zvivakwa kuti ive yakasarudzika chigadzirwa chine akawanda mashandisiro, uye akasiyana zvivakwa ndeaya anotevera:

(1) Kuchengeta mvura: Inogona kuchengeta mvura panzvimbo dzine porous semapuranga esimende mabhodhi nezvidhinha.

(2) Magadzirirwo efirimu: Inogona kuumba firimu rakajeka, rakaoma uye rakapfava rine yakanakisa mafuta kuramba.

(3) Organic solubility: Chigadzirwa chacho chinonyungudika mune zvimwe organic solvents, senge ethanol/mvura, propanol/mvura, dichloroethane, uye solution system inoumbwa neaviri organic solvents.

(4) Thermal gelation: Kana iyo aqueous solution yechigadzirwa ichipisa, ichaita gel, uye gel yakaumbwa ichava mhinduro zvakare mushure mekutonhora.

(5) Chiitiko chepamusoro: Ipa chiitiko chepamusoro mumhinduro kuti uwane iyo inodiwa emulsification uye inodzivirira colloid, pamwe nekudzikamisa kwechikamu.

(6) Kumiswa: Inogona kudzivirira kunaya kwezvimedu zvakasimba, nokudaro zvichidzivisa kuumbwa kwe sediment.

(7) Protective colloid: inogona kudzivirira madonhwe uye zvimedu kubva pakubatana kana kubatana.

(8) Kunamira: Inoshandiswa sechinamira yemavara, zvigadzirwa zvefodya, uye zvigadzirwa zvemapepa, ine basa repamusoro.

(9) Kunyungudika kwemvura: Chigadzirwa chacho chinogona kunyungudutswa mumvura muhuwandu hwakasiyana, uye huwandu hwayo hwepamusoro hunongogumira ne viscosity.

(10) Non-ionic inertness: Chigadzirwa i-non-ionic cellulose ether, isingabatanidzi nesimbi yemunyu kana mamwe ayoni kuti igadzire mvura isinganyunguriki.

(11) Acid-base kugadzikana: yakakodzera kushandiswa mukati mehuwandu hwePH3.0-11.0.

(12) Kusanaka uye kunhuhwirira, kusakanganiswa nemetabolism; inoshandiswa sechikafu uye zvinodhaka zvinowedzera, hazvizogadziriswi muzvokudya uye hazvizopi macalories.
