Ngaba i-hypromellose yendalo?

I-Hypromellose, ekwabizwa ngokuba yi-hydroxypropyl methylcellulose (HPMC), i-polymer ye-semisynthetic ephuma kwi-cellulose, i-polymer yendalo efumaneka kwiindonga zeseli zezityalo. Ngelixa i-cellulose ngokwayo iyindalo, inkqubo yokuyiguqula ukuze yenze i-hypromellose ibandakanya ukuphendulwa kweekhemikhali, okwenza i-hypromellose ibe yi-semisynthetic compound.

Ukuveliswa kwe-hypromellose kubandakanya ukuphatha i-cellulose nge-propylene oxide kunye ne-methyl chloride ukwazisa i-hydroxypropyl kunye namaqela e-methyl kumqolo we-cellulose. Olu hlengahlengiso luguqula iipropati zeselulosi, lunike i-hypromellose iimpawu zayo ezizodwa ezifana nokunyibilika kwamanzi, amandla okwenza ifilimu, kunye ne-viscosity.

Nangona i-hypromellose ayifumanekanga ngokuthe ngqo kwindalo, ivela kumthombo wendalo (i-cellulose) kwaye ithathwa njenge-biocompatible kunye ne-biodegradable. Isetyenziswa kakhulu kumayeza, iimveliso zokutya, izithambiso, kunye nezicelo ezahlukeneyo zemizi-mveliso ngenxa yokhuseleko lwayo, ukuguquguquka, kunye nokusebenza.

Isishwankathelo, ngelixa i-hypromellose iyikhompawundi ye-semisynthetic, imvelaphi yayo kwi-cellulose, i-polymer yendalo, kunye ne-biocompatibility yayo yenza ukuba ibe yinto eyamkelwe ngokubanzi kwizicelo ezahlukeneyo.
