Chii chinogadzirwa nehypromellose?

Hypromellose, inozivikanwawo se hydroxypropyl methylcellulose (HPMC), ipolymer inogadzirwa kubva ku cellulose, inova polymer inowanikwa mumadziro esero emiti. Heino magadzirirwo e hypromellose:

1. Kutsvaga Cellulose: Maitiro acho anotanga nekutsvaga cellulose, iyo inogona kuwanikwa kubva kumiti yakasiyana-siyana yakadai sehuni, machira edonje, kana zvimwe zvirimwa zvine fibrous. Cellulose inowanzo torwa kubva kumiti iyi kuburikidza nemaitiro akasiyana-siyana emakemikari uye emakanika kuti iwane cellulose yakacheneswa.
2. Kugadziriswa kweEther: Cellulose yakacheneswa inoitwa nenzira yekuchinja makemikari inonzi etherification, uko mapoka ehydroxypropyl nemethyl anoiswa pamusana wecellulose. Kugadziriswa uku kunoitika nekubatanidza cellulose nepropylene oxide (kuunza mapoka ehydroxypropyl) uye methyl chloride (kuunza mapoka emethyl) pasi pemamiriro ezvinhu akadzorwa.
3. Kucheneswa uye Kugadziriswa: Mushure mekupiswa, chigadzirwa chinobuda chinocheneswa kubvisa tsvina nezvimwe zvinobva mukuita kwechinhu ichi. Hypromellose yakacheneswa inozogadzirwa kuita mhando dzakasiyana dzakadai sehupfu, granules, kana mhinduro, zvichienderana nekushandiswa kwayo.
4. Kudzora Hunhu: Mukati mekugadzirwa kwezvinhu, matanho ekudzora hunhu anoshandiswa kuona kuchena, kuenderana, uye kushanda kwechigadzirwa chehypromellose. Izvi zvinosanganisira kuyedza zvinhu zvakaita sehuremu hwemamorekuru, viscosity, kunyungudika, nezvimwe zvinhu zvemuviri nemakemikari.
5. Kurongedza uye Kugovera: Kana chigadzirwa chehypromellose chasvika padanho remhando yepamusoro, chinoiswa mumagaba akakodzera uye chinogoverwa kumaindasitiri akasiyana-siyana kuti chishandiswe mumishonga, zvigadzirwa zvekudya, zvizoro, nezvimwewo.

Kazhinji, hypromellose inogadzirwa kuburikidza nematanho akasiyana-siyana emakemikari anodzorwa uye matanho ekuchenesa anoshandiswa ku cellulose, zvichikonzera polymer inoshandiswa zvakasiyana-siyana uye inoshandiswa zvakanyanya ine mashandisirwo akasiyana-siyana mumaindasitiri akasiyana-siyana.
