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

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.
