Yintoni iHypromellose?

IHypromellose, ekwaziwa ngokuba yi-hydroxypropyl methylcellulose (HPMC), yipolymer eyenziweyo evela kwiselulosi.Sisithako esisetyenziswa kakhulu kumashishini ahlukeneyo, kubandakanya amayeza, ukutya, izinto zokuthambisa, kunye nokwakha.Le khompawundi iguquguqukayo ineempawu ezizodwa eziyenza ixabiseke kuluhlu lwezicelo.

Ulwakhiwo lweMichiza kunye neePropati:

I-Hypromellose yi-ether ye-cellulose kunye nefomula yekhemikhali (C6H7O2 (OH) 3-x (OC3H7) x) n, apho i-x imele iqondo lokutshintshwa kwe-hydroxypropyl kunye namaqela e-methoxy.Ulwakhiwo lwalo lubandakanya ikhonkco leyunithi yeeyunithi ze-glucose, ezifana neselulosi yendalo, kodwa kunye namanye amaqela e-hydroxyl athatyathelwe indawo ye-hydroxypropyl kunye namaqela e-methoxy.Olu tshintsho luguqula iimpawu zalo zomzimba kunye neekhemikhali xa kuthelekiswa neselulosi.

IHypromellose ifumaneka kumabakala ahlukeneyo ngokuxhomekeke kwi-viscosity yayo kunye nobunzima bemolekyuli.Amabanga ahlukeneyo anikezela ngeendidi ze-viscosity ezahlukeneyo, ezimisela ukusebenza kwayo kwizicelo ezahlukeneyo.Amanqanaba aphezulu e-viscosity ahlala esetyenziswa kwii-pharmaceuticals njenge-thickening agents, ngelixa amabakala asezantsi e-viscosity afanelekile kwizicelo ezifana neengubo kunye ne-adhesives.
