Nibihe bintu bya Shimi bya Hypromellose?

Hydroxypropyl Methylcellulose (HPMC), izwi kandi nka Hypromellose, ni polymer synthique ikomoka kuri selile. Ibikoresho bya shimi birimo:

1. Gukemura: HPMC ibora mumazi kandi ikora igisubizo gisobanutse iyo ivanze namazi. Gukemura kwa HPMC biterwa nurwego rwo gusimbuza (DS) hamwe nicyiciro cya viscosity.
2. Viscosity: HPMC iraboneka mubyiciro bitandukanye byubwiza, kuva hasi kugeza hejuru cyane. Ubukonje bwa HPMC buterwa n'uburemere bwacyo, urugero rwo gusimbuza, hamwe no kwibanda.
3. Igihagararo: HPMC irahagaze mubihe bisanzwe byubushyuhe na pH. Irwanya kwangirika kwa mikorobe kandi ntishobora kubora byoroshye.
4. Imiterere yubushyuhe: HPMC ifite ubushyuhe bwiza kandi irashobora kwihanganira ubushyuhe bugera kuri 200 ° C itabora.
5. Igikorwa cyubuso: HPMC ifite ibikorwa byubuso bitewe na polar yayo, ituma iba ingirakamaro nka dispersant na emulsifier mubikorwa bitandukanye.
6. Hygroscopicity: HPMC ni hygroscopique, bivuze ko ifite impengamiro yo gukuramo ubuhehere buturuka ku bidukikije. Uyu mutungo utuma ugira akamaro nkumukozi ugumana amazi mubikorwa bitandukanye.
7. Imiti yimiti: HPMC yinjizwamo imiti kandi ntabwo ikora nindi miti. Nyamara, irashobora gukora hydrogène ihuza hamwe nizindi molekile ya polar, bigatuma igira akamaro nkibibyimbye, binder, na firime-yahoze mubikorwa bitandukanye.

Muri make,HPMCifite imiti myinshi yimiti ituma polymer ihinduka kandi yingirakamaro mubikorwa bitandukanye, harimo imiti, ibiryo, amavuta yo kwisiga, nubwubatsi. Ihinduka ryayo, ibishishwa, ituze, imiterere yubushyuhe, ibikorwa byubuso, hygroscopicity, hamwe nubushakashatsi bwimiti bituma bikwiranye nibikorwa byinshi.
