Hydroxypropyl Methylcellulose HPMC E3, E5, E6, E15, E50, E4M

Hydroxypropyl Methylcellulose (HPMC) bụ cellulose ether nwere akara ule dị iche iche, nke ejiri mkpụrụedemede na ọnụọgụ gosipụtara. Akara ule ndị a na-anọchi anya nkọwapụta dị iche iche, gụnyere ọdịiche dị na ịdị arọ molekụla, ọdịnaya hydroxypropyl, na viscosity. Nke a bụ nbibi nke akara ule HPMC ị kwuru:

1. HPMC E3:
   • O yikarịrị ka ọkwa a na-ezo aka na HPMC nwere otu viscosity 2.4-3.6CPS. Nọmba 3 na-egosi viscosity nke ngwọta mmiri 2%, ọnụ ọgụgụ dị elu na-egosikwa viscosity dị elu.
2. HPMC E5:
   • Yiri E3, HPMC E5 na-anọchi anya ọkwa viscosity dị iche. Nọmba 5 na-egosi viscosity dị 4.0-6.0 CPS nke ngwọta mmiri 2%.
3. HPMC E6:
   • HPMC E6 bụ ọkwa ọzọ nwere profaịlụ viscosity dị iche. Nọmba 6 na-egosi viscosity 4.8-7.2 CPS nke ngwọta 2%.
4. HPMC E15:
   • HPMC E15 nwere ike na-anọchite anya ọkwa viscosity dị elu ma e jiri ya tụnyere E3, E5, ma ọ bụ E6. Nọmba 15 na-egosi viscosity 12.0-18.0CPS nke ngwọta mmiri 2%, na-atụ aro nkwụsi ike siri ike.
5. HPMC E50:
   • HPMC E50 na-egosi ọkwa viscosity dị elu, yana ọnụọgụ 50 na-anọchite anya viscosity 40.0-60.0 CPS nke ngwọta 2%. O yikarịrị ka ọkwa a ga-enwe viscosity dị elu nke ukwuu ma e jiri ya tụnyere E3, E5, E6, ma ọ bụ E15.
6. HPMC E4m:
   • “m” dị na E4m na-egosipụtakarị viscosity ọkara 3200-4800CPS. HPMC E4m na-anọchi anya ọkwa nwere ọkwa viscosity na-agafeghị oke. Ọ nwere ike ịdị mma maka ngwa chọrọ nguzozi n'etiti mmiri na ọkpụrụkpụ.

Mgbe ị na-ahọpụta ọkwa HPMC maka otu ngwa, ntụle gụnyere viscosity achọrọ, solubility na njirimara arụmọrụ ndị ọzọ. A na-ejikarị HPMC eme ihe n'ụlọ ọrụ dịka ihe owuwu, ụlọ ọgwụ, ihe ịchọ mma, na nri.

N'ime nri, a na-ejikarị HPMC eme ihe dị ka mgbakwunye na ngwaahịa ndị na-abụghị mmiri ara ehi iji melite akụrụngwa dị ka njide mmiri, ịrụ ọrụ, na nrapado. Na pharmaceuticals na ịchọ mma, HPMC na-eji maka ya film-akpụ na thickening Njirimara.

Ọ dị mkpa ka gị na onye nrụpụta ma ọ bụ onye na-ebubata ya kparịta maka inweta ozi teknụzụ zuru ezu, gụnyere nkọwapụta yana ngwa akwadoro maka ọkwa HPMC ọ bụla. Ndị na-emepụta ihe na-enyekarị akwụkwọ data teknụzụ na akwụkwọ ngwaahịa iji duzie ndị ọrụ n'ịhọrọ ọkwa kacha dabara adaba maka mkpa ha.
