Methy Cellulose (Mc) na hydropyylthylthyl methylcellose (hpmc) bụ nke na-ejikarị ọgwụ, nri, ihe na-ewu ụlọ na ubi ndị ọzọ. Ọ bụ ezie na ha enwetala site na sellulose ma nwee ọrụ ndị yiri ya na ụfọdụ, ha nwere ọdịiche dị iche iche na usoro kemịkal, akụrụngwa, ngwa ngwa na njiri arụ ọrụ.
1. Ihe nhazi kemịkado na usoro nkwadebe
Methyl cellulose (mc) na-emepụta site na dochie akụkụ ma ọ bụ otu hydroxy dị iche iche (-Oh) nke methoxy otu (-OH). Kpọsị, ìgwè hydroxy na celllose si emeghachi omume na methylating reregres (dị ka methych chloride) n'okpuru ọnọdụ alkaline iji mepụta methylcellose. N'ihi ogo dị iche iche, mc nwere ike ịnwe nkwado dị iche na viscosity.
A na-agbanwegharị hydroxyl methylcellose (hpmc): nke ahụ bụ, na celdrose solulose, kama akụkụ nke celdropyyl na-eji hydroxyl. Nkwadebe nke HPMC na-emetụta mmeghachi omume abụọ: mbụ meghe mmeghachi omume ma meghachi omume hydroxyPropy. N'ihi nnọchi a okpukpu abụọ, Njirimara nke HPMC dị mgbagwoju anya ma dị iche iche.
2. Ngwọta na Njirimara Njirimara
Solublity nke mc: Methylcellose nwere ezigbo sonubility na mmiri oyi, mana ọ naghị agbari na mmiri ọkụ. Ngwọta ya ga-amịpụta gel mgbe ọ na-agba ọkụ, nke na-eme ka MC nwere uru dị iche iche n'okpuru ụfọdụ ọnọdụ, dịka ntinye ya na akụrụngwa.
Ekwenyere na HPMC: N'ụzọ dị iche, Hpmc na-soluble na mmiri oyi na mmiri ọkụ, yana ihe ngwọta ya nwere ụdị viscosity dị egwu. Na mgbakwunye, HPMC na-egosipụta nkwụsi ike na ngwọta na enweghị mmetụta na mgbanwe na uru Phy, yabụ na-eji ya n'ọtụtụ ụlọ ọgwụ na ọgwụ ọgwụ.
3. Ebe ntinye
Ngwa nke methylcellose: N'ihi ihe ndị na-ahụ maka ikuku na-ejigide onye na-ahụ maka MC, ọkachasị na ihe owuwu dị ka emulsifier na ndị isi nri iji nyere aka melite uto na nkwụsi ike nke nri. N'ime ụlọ ọrụ ọgwụ, mgbe ụfọdụ, a na-eji Mc dị ka onye na-eme ihe maka mbadamba maka mbadamba na ihe nkiri maka capsules.
Ngwa nke hydroxypylthylthylthylcellose: hpmc dị nnọọ iche karịa MC n'ọtụtụ ụlọ ọrụ n'ihi ndọtị ụkwụ ya na nkwụsi ike ya. Iji maa atụ, a na-eji HPMC mee ihe n'ọtụtụ ọgwụ iji kwadebe mbadamba ihe na nke Capsule shells, yana dị ka nke na-eto eto na lubricant maka nkwadebe Ophthalmic. N'ime ihe eji eme ihe, a na-eji HPMC na-ejikarị ya dị ka onye na-echekwa na mmiri na-ejigide ngwa ngwa, na-eme ka ọ na-eme ihe. Na mgbakwunye, a na-eji HPMC na-ejikwa dị ka nke ukwu, emulsifier na mmachi na ọrụ nri.
4. Akụkụ arụmọrụ na arụmọrụ arụmọrụ
Njirimara nke MC: Akụkụ pụrụ iche nke methylcellose bụ ihe na-acha uhie uhie, nke na-eme ka ọ dị irè na ngwa chọrọ nkwụsi ike. Na mgbakwunye, ihe okirikiri nke Mc nwere ụfọdụ nghọta na elu ọrụ, nke bara uru n'ọtụtụ usoro mmepụta ihe.
A na-egosipụta njirimara nke HPMC: hydroxypylthylthylthylthylthylthylthylcelllose bụ ihe a na-ejikwa ya na njikwa ya na ngwọta ngwọta ya, na nkwụsi ike ya dị ka okpomoku na pH. Njirimara ndị a na-eme ka HPMC gosipụta oke mgbanwe na nkwụsi ike na ngwa dị iche iche. Na mgbakwunye, nje ụlọ ọrụ HPMC na ihe na-adịghị mma na-eme ka ọ dị ezigbo mkpa na ụlọ ọrụ ọgwụ na nri.
5. Nchedo gburugburu na nchekwa
Ngwongwo nke MC na HPMC: Dịka Cellulose derivatives, MC na HPMC bụ ihe dị iche iche na gburugburu ebe obibi. Na mgbakwunye, ihe ma ihe ma ihe na-adịghị egbu egbu, na-enweghị mgbakasị ma dị mma, na-eme ka ha dị mma maka iji ebe mmadụ na-akpọ mmadụ, dị ka nri na ọgwụ.
Ọ bụ ezie na methylcellose (mc) na hydropyylmethylcelllose (HPMC) nwere myirịta na kemịkalụ na njiri mara dị iche n'ihi ndị dị iche iche. E nwere ọdịiche dị ukwuu. MC tumadi Omumaputa na ngwa ndi choro ihe ndi ozo Ọ bụ ezie na a na-eji HPMC mee ihe n'ọtụtụ ọgwụ, nri na ụlọ ọrụ na-arụ ọrụ n'ihi ngegedulity, nkwụsi ike na enweghị oke mma. Ghọta ọdịiche dị n'etiti ha abụọ nwere ike inyere gị aka ịhọrọ ihe kwesịrị ekwesị maka ngwa ụfọdụ.
