Hydroxypropyl methylcellulose, 28-30% metoxyl, 7-12% hydroxypropyl.

Nkọwapụta "28-30% methoxyl" na "7-12% hydroxypropyl" na-ezo aka n'ogo nke nnọchi naHydroxypropyl Methylcellulose(HPMC). Ụkpụrụ ndị a na-egosi ókè ejirila kemịkalụ methoxyl na otu hydroxypropyl gbanwee ihe mbụ cellulose polymer.

1. 28-30% Methoxyl:
   • Nke a na-egosi na, na nkezi, 28-30% nke mbụ hydroxyl otu dị na cellulose molecule ka ewerewo otu methoxyl dochie ya. A na-ewebata otu Methoxyl (-OCH3) iji mee ka hydrophobicity nke polymer dịkwuo elu.
2. 7-12% Hydroxypropyl:
   • Nke a na-egosi na, na nkezi, 7-12% nke mbụ hydroxyl otu dị na cellulose molecule ka ejiri otu hydroxypropyl dochie ya. A na-ewebata otu Hydroxypropyl (-OCH2CHOHCH3) iji welie mmiri solubility ma gbanwee ihe anụ ahụ na kemịkal ndị ọzọ nke polymer.

Ogo nke nnọchi na-emetụta njirimara nke HPMC yana arụmọrụ ya na ngwa dị iche iche. Ọmụmaatụ:

• Ọdịnaya methoxyl dị elu n'ozuzu na-abawanye hydrophobicity nke polymer, na-emetụta solubility mmiri ya na ihe ndị ọzọ.
• Ọdịnaya hydroxypropyl dị elu nwere ike ịkwalite solubility mmiri na ihe na-emepụta ihe nkiri nke HPMC.

Nkọwa ndị a dị oke mkpa n'ịkwado HPMC iji mezuo ihe achọrọ n'ọrụ dị iche iche. Dịka ọmụmaatụ, na ụlọ ọrụ ọgwụ, nhọrọ nke akara HPMC nwere ogo nnọchi anya nwere ike imetụta profaịlụ mwepụta ọgwụ na usoro mbadamba. N'ime ụlọ ọrụ na-ewu ụlọ, ọ nwere ike imetụta njide mmiri na njigide nke ngwaahịa ndị sitere na ciment.

Ndị na-emepụta ihe na-emepụta akara ule dị iche iche nke HPMC nwere ogo dị iche iche nke nnọchi iji gboo mkpa dị iche iche nke ngwa dị iche iche. Mgbe ị na-eji HPMC n'ụdị nhazi, ọ dị mkpa ka ndị na-emepụta ihe tụlere ọkwa nke HPMC nke dabara na njirimara achọrọ yana njirimara arụmọrụ maka ngwa ezubere.
