Hydroxypylththththththylcelllose (hpmc)bụ ihe na-ejikarị ngwa cellose na-ejikarị ngwa, karịchaa n'ọhịa nke ọgwụ, ihe ịchọ mma, nri, na ụlọ. Ọ bụghị ihe mgbakwasị, ma polymer-soluble nke nwere ike igbari na mmiri ma na-etolite ngwọta colloidal. Ekwesịrị ịdọ aka na ntị na-adabere na ọnụ ọgụgụ na ọnọdụ nke methyl na hydroxypppyyl dị na usoro ya.
1. Njirimara nke ihe eji eme ihe eji eme ihe
A na-enweta Hydropylithyththththththyththylcelllose na-enweta site na methylition na hydroxypyplation nke cellose. Cellulose n'onwe ya bụ polsilaride molecular dị na mgbidi osisi. Ọdịmma kemịkalụ nke Hpmc bụ tumadi mejupụtara akụkụ glucose, nke na-adịte aka nke na-ejikọ anya site na agbụ Glycosidic. N'ime usoro ihe omume a, a na-eji methyl dị iche iche site na Methyl (nke Hydroxyl) na hydroxyl (-c₃h₇ov (-c₃h₇oh), na-enye ya ezigbo solible na akụrụngwa anụ ahụ na kemịkal ndị ọzọ.
Mkpa ike nke HPMC na-emetụta ya ma na-enwekarị njirimara ndị a:
Mmiri solubility: HPMC nwere ike ịmalite ngwọta viscous na mmiri ma na-agbaze ngwa ngwa. Ihe ndọpụ ya nwere njikọ chiri anya na okpomọkụ nke mmiri na ịdị arọ molecular nke hpmc.
Visity dị elu: na ụfọdụ ịta, ihe ngwọta nke HPMC na-egosi viscosity dị elu, ọkachasị na oke molecular dị elu.
Nkwụsị ọkụ ahụ: HPMC nwere ezigbo nkwụsi ike na ọnọdụ okpomọkụ na adịghị mfe ịkpụ, yabụ na ọ nwere uru ụfọdụ na usoro nhazi ọkụ.
2. Nkwelite HPMC
HPMC bụ ihe na-agbanye mmiri, mana ọ bụghị ihe mgbaze niile anaghị agbaze. Omume rụrụ arụ bụ ihe metụtara polaraty nke ihe mgbatị ahụ na mmekọrịta dị n'etiti molecules na ụmụ irighiri ihe HPMC.
Mmiri: A ga-agbaze hpmc na mmiri. Mmiri bụ ihe mgbaze ya kachasị ukwuu, na n'oge usoro a na-agbasa, na-eme usoro ụmụ irighiri mmiri ga-etolite agbụ hydrogen na molecules mmiri iji nweta mgbasa. A na-emetụta ogo nke mgbasa na nke HPMC, ogo methy na hydroxyprotion, okpomọkụ, na uru mmiri. Ọtụtụ mgbe, ị na-eso ụzọ HPMC kacha mma na mpaghara igwe na-anọpụ iche.
Ihe mgbazinye ihe onunu: hpmc fọrọ nke nta ka ọ ghara ikwenye n'ihe mgbochi ndị ọfụma, dịka mmanya, dị ka mmanya, dị ka mmanya, na hydrocarbons. Nke a bụ n'ihi na ihe owuwu ya nwere hydroxy Hydroxy n'otu na lipophilic otu na ìgwè hydroxypyl. Ọ bụ ezie na ọ nwere ike ịdị na-enwe siri ike maka mmiri, ọ na-enwe ndakọrịta na ọtụtụ soncher ndị otu.
Mmiri mmiri na-ekpo ọkụ, na mmiri ọkụ (ọ na-abụkarị 40 Celsius C ruo 70 Celsius C), HPMC agbasasịwo ngwa ngwa na-egosiputa viocosict. Ka ọnọdụ okpomọkụ na-abawanye, ọnụego mgbasa ozi ga-abawanye, mana na oke okpomọkụ, ọdịdị visce nke ihe ngwọta.
3. Ngwa nke HPMC
N'ihi ezigbo mmiri solbality, na viocosity dị ala, na viscosity na-agbanwe agbanwe, HPMC na-eji ya n'ọtụtụ ụlọ ọrụ.
A na-eji ụlọ ọrụ na-emepụta ọgwụ: N'ụlọ ọgwụ na-arụpụta ọgwụ, nke a na-ejikarị njikere maka ọgwụ ọgwụ, na-akpụzi, gels, na ndị na-ebu ọgwụ ọjọọ. Ọ nwere ike inyere ọgwụ ọjọọ na mmiri ma mezie ọnụego nke ịgha ọgwụ.
Industrylọ ọrụ nri: HPMC, dị ka ihe mgbakwunye nri nri, a na-ejikarị emulsification, na-emekwa mmiri. Na ngwongwo ndị a na-eme achịcha, ọ nwere ike melite ịkpụzi na nkwụsi ike mgwakota agwa. A na - ejikarị HPMC na ice cream, ihe ọ beụveụ na nri ndị dị ala.
Industrylọ ọrụ owuwu: N'ụlọ ọrụ owuwu: A na-ejikarị HPMC na-ejikarị ya dị ka onye na-eme ihe maka ngwa agha, nke nwere ike imezi arụmọrụ owuwe ihe, njigide mmiri na ike mmiri na ike.
A na-eji ihe ịchọ mma:
HpmcBụ mmiri na-agbanye mmiri na nke ukwuu viocoutive vionose derivative nke nwere ike ịhazi ihe ngwọta na mmiri. Ọ bụghị ihe mgbaze, mana ogige molecular nke nwere ike igbari na mmiri. A na-egosipụta akụkụ ya na-egosi na mmiri dị mma na mmiri, ma na-egbochi ọtụtụ sonchents. Njirimara ndị a na-eme ka ọ rụọ ya n'ọtụtụ ụlọ ọrụ, gụnyere ọgwụ, nri, owuwu, na ihe ịchọ mma.
