Ọdịiche dị n'etiti EHEC na HPMC

EHEC na HPMC bụ ụdị polymers abụọ a na-ejikarị nwere usoro na akụrụngwa dị iche iche. EHEC na-anọchi anya ethyl hydroxyethyl cellulose, ebe HPMC na-anọchi anya hydroxypropyl methylcellulose. N'isiokwu a, anyị ga-atụle ọdịiche dị n'etiti EHEC na HPMC n'ihe gbasara usoro kemịkalụ ha, ihe onwunwe, ojiji na nchekwa.

1. Ọdịdị Chemical

EHEC bụ polymer soluble mmiri nke sitere na cellulose. Ọ bụ cellulose ether gbanwetụrụ nke nwere ma ethyl na hydroxyethyl dị iche iche jikọtara na ọkpụkpụ azụ cellulose. Ogo nke nnọchi (DS) nke EHEC na-ezo aka ọnụ ọgụgụ nke ethyl na hydroxyethyl dị iche iche nke dị na otu anhydroglucose (AGU) nke ọkpụkpụ azụ cellulose. DS nke EHEC nwere ike si na 0.2 ruo 2.5, yana ụkpụrụ DS dị elu na-egosi ọkwa dị elu nke ngbanwe.

N'aka nke ọzọ, HPMC bụkwa polymer soluble mmiri nke sitere na cellulose. Ọ bụ cellulose ether gbanwetụrụ nke nwere ma hydroxypropyl na methyl dị iche iche jikọtara na ọkpụkpụ azụ cellulose. Ogo nke nnọchi nke HPMC na-ezo aka na ọnụọgụ hydroxypropyl na methyl dị ugbu a kwa AGU nke ọkpụkpụ azụ cellulose. DS nke HPMC nwere ike si na 0.1 ruo 3.0, yana ụkpụrụ DS dị elu na-egosi ogo ngbanwe dị elu.

2. Njirimara

EHEC na HPMC nwere ihe dị iche iche na-eme ka ha dị mma maka ngwa dị iche iche. Ụfọdụ n'ime ihe ndị bụ isi nke EHEC na HPMC ka edepụtara n'okpuru:

a. Solubility: EHEC dị obere soluble na mmiri karịa HPMC, na solubility ya na-ebelata ka ogo nke nnọchi na-abawanye. N'aka nke ọzọ, HPMC na-agbaze nke ukwuu na mmiri.

b. Rheology: EHEC bụ ihe pseudoplastic, nke pụtara na ọ na-egosipụta àgwà mkparị. Nke a pụtara na viscosity nke EHEC na-ebelata ka ọnụ ọgụgụ shear na-abawanye. N'aka nke ọzọ, HPMC bụ ihe Newtonian, nke pụtara na viscosity ya na-anọgide na-adịgide adịgide n'agbanyeghị ọnụ ọgụgụ shear.

c. Ihe na-emepụta ihe nkiri: EHEC nwere ezigbo ihe nkiri na-emepụta ihe nkiri, nke na-eme ka ọ dị mma maka iji mkpuchi na ihe nkiri. HPMC nwekwara ihe ndị na-emepụta ihe nkiri, mana ihe nkiri ahụ nwere ike na-agbakasị ma na-enwekarị mgbawa.

d. Nkwụsi ike: EHEC kwụsiri ike n'ọtụtụ pH na ọnọdụ okpomọkụ. HPMC kwụsiri ike karịa oke pH, mana oke okpomọkụ nwere ike imetụta nkwụsi ike ya.

3. Na-eji

A na-eji EHEC na HPMC n'ọtụtụ ngwa dị iche iche na nri, ọgwụ na ụlọ ọrụ nlekọta onwe onye. Ụfọdụ n'ime isi ojiji EHEC na HPMC bụ ndị edepụtara n'okpuru:

a. Ụlọ ọrụ nri: A na-ejikarị EHEC eme ihe dị ka ihe na-esi ísì, stabilizer, na emulsifier na ngwaahịa nri dị ka sauces, uwe, na ngwaahịa esi nri. A na-ejikwa HPMC dị ka thickener na stabilizer na ngwaahịa nri, mana a na-ejikarị ya dị ka ihe mkpuchi maka ngwaahịa confectionery dị ka candies gummy na chocolates.

b. Ụlọ ọrụ na-emepụta ọgwụ: A na-eji EHEC mee ihe dị ka onye na-ekekọta, nkwụsịtụ, na onye na-ekpuchi mbadamba nkume na usoro ọgwụ. A na-ejikwa HPMC dị ka onye na-ekekọta ihe, disintegrant, na mbadamba ihe mkpuchi n'ụdị ọgwụ, mana a na-ejikarị ya dị ka ihe ntọhapụ na-adịgide adịgide.

4. Nchekwa

A na-ewerekarị EHEC na HPMC dị mma maka iji nri na ngwa ọgwụ. Agbanyeghị, dịka ọ dị na kemịkal ọ bụla, enwere ike ịnwe ụfọdụ ihe egwu jikọtara ya na ojiji ha.
