Hypromellose ikorwa niki?

Hypromellose, izwi kandi ku izina rya hydroxypropyl methylcellulose (HPMC), ni polimeri ya semisintetike ikomoka kuri selile, ikaba ari polymer isanzwe iboneka mu rukuta rw'utugingo ngengabuzima. Dore uko hypromellose ikorwa:

1. Isoko rya selile: Inzira itangirana no gushakisha selile, ishobora kuboneka mumasoko atandukanye y'ibimera nk'ibiti by'ibiti, fibre y'ipamba, cyangwa ibindi bimera bya fibrous. Cellulose isanzwe ikurwa muri aya masoko ikoresheje uburyo bwa chimique na mashini kugirango ibone ibikoresho bya selile.
2. Etherification: Cellulose isukuye ikora inzira yo guhindura imiti yitwa etherification, aho hydroxypropyl na methyl zinjizwa mumugongo wa selile. Ihinduka ryagerwaho mugukora selile hamwe na oxyde ya propylene (kumenyekanisha amatsinda ya hydroxypropyl) na methyl chloride (kumenyekanisha amatsinda ya methyl) mugihe cyagenwe.
3. Isuku no Gutunganya: Nyuma ya etherification, ibicuruzwa bivamo bigenda bisukurwa kugirango bikureho umwanda nibicuruzwa biva mubitekerezo. Hypromellose isukuye noneho itunganyirizwa muburyo butandukanye nka poro, granules, cyangwa ibisubizo, bitewe nubushake bwayo.
4. Kugenzura ubuziranenge: Mubikorwa byose byo gukora, ingamba zo kugenzura ubuziranenge zishyirwa mubikorwa kugirango harebwe ubuziranenge, ubudahwema, n'imikorere y'ibicuruzwa bya hypromellose. Ibi birimo kwipimisha ibipimo nkuburemere bwa molekuline, viscosity, solubile, nibindi bintu bifatika na chimique.
5. Gupakira no gukwirakwiza: Igicuruzwa cya hypromellose kimaze kuba cyujuje ubuziranenge, gipakirwa mu bikoresho byabigenewe kandi kigabanywa mu nganda zitandukanye kugira ngo gikoreshwe mu bya farumasi, ibikomoka ku biribwa, kwisiga, n'ibindi bikorwa.

Muri rusange, hypromellose ikorwa hifashishijwe urukurikirane rwimiti igenzurwa nintambwe yo kweza ikoreshwa kuri selile, bikavamo polymer zitandukanye kandi zikoreshwa cyane hamwe nibikorwa bitandukanye mubikorwa bitandukanye.
