Hypromellose 2208 ndi 2910

Hypromellose, yomwe imadziwikanso kuti hydroxypropyl methylcellulose (HPMC), ndi ether yopanda poizoni komanso yopanda ionic yomwe imagwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikiza mankhwala, zodzoladzola, ndi zakudya. HPMC imapezeka m'makalasi osiyanasiyana, kuphatikizapo Hypromellose 2208 ndi 2910, omwe ali ndi katundu ndi ntchito zosiyanasiyana.

Hypromellose 2208 ndi kalasi yotsika ya viscosity ya HPMC yomwe imagwiritsidwa ntchito ngati binder, thickener, ndi filimu kale muzamankhwala. Nthawi zambiri amagwiritsidwa ntchito popaka mapiritsi, pomwe amapereka mawonekedwe osalala, onyezimira komanso amawongolera kukhazikika kwa piritsi. Hypromellose 2208 imagwiritsidwanso ntchito popanga mawonekedwe a ophthalmic, pomwe imagwira ntchito ngati mafuta ndikuwongolera kukhuthala kwa kapangidwe kake.

Hypromellose 2910 ndi kalasi yapamwamba ya viscosity ya HPMC yomwe imagwiritsidwa ntchito ngati thickener, binder, ndi emulsifier mu ntchito zosiyanasiyana. M'zamankhwala, nthawi zambiri amagwiritsidwa ntchito ngati wothandizira nthawi zonse, chifukwa amatulutsa pang'onopang'ono zomwe zimagwira ntchito pakapita nthawi. Hypromellose 2910 amagwiritsidwanso ntchito mu zodzoladzola, kumene amapereka zotsatira thickening, bwino kukhazikika kwa emulsions, ndi kumawonjezera kapangidwe ka mankhwala.

Mwachidule, Hypromellose 2208 ndi 2910 ndi magulu awiri a HPMC okhala ndi katundu ndi ntchito zosiyanasiyana. Hypromellose 2208 ndi giredi yotsika yama viscosity yomwe imagwiritsidwa ntchito m'zamankhwala, pomwe Hypromellose 2910 ndi giredi yapamwamba kwambiri yomwe imagwiritsidwa ntchito muzamankhwala, zodzoladzola, ndi ntchito zina.
