Hydroxypylthlthyth methylcellose (hpmc) bụ osisi polymer na-agbanye mkpọrọgwụ na cellulose derivative. A na-eji ya na ọgwụ, ihe owuwu, nri, ihe ịchọ mma na ubi ndị ọzọ. HPMC nwere ụfọdụ akụrụngwa anụ ahụ pụrụ iche na kemịkal nke ihe owuwu molulose, nke na-ezute mkpa ụlọ ọrụ mmepụta ihe dị iche iche.
1. Ihe omume molecular na akụrụngwa
Ihe owuwu nke HPMC mejuputara ọkpụkpụ mkpụrụ osisi cellugul na ndị dị iche iche (hydroxyppyyl na methyl). Site na ngbanwe kemịkal, a na-ewebata otu na Methyl na Methyl, nke na-enye ya mmiri solbility, na-eto, na-akpụ akpụ na ihe ndị ọzọ. N'ihi ihe okike nke HPMC, ọ na-egbochi mmiri na mmiri na-edozi ahụ, mana nwere ike ịpụta ngwọta compodal na mmiri.
Ndị otu Hydropopy na-abawanye hydrophility, ebe otu methyl na-eme ka hydrophodicy na-eme ka hydrophodicy. Site na idozi oke nke ndị a, mmiri solubality, sọsọ mmiri, viscosity na akụrụngwa ndị ọzọ nke HPMC nwere ike ịgbanwe mkpa nke ngwa dị iche iche.
2. Ngwọta na Hydration
HPMC nwere ezigbo sonubity, ọkachasị mgbe etisasịwo na mmiri ọkụ, ọ ga-etolitekwa edo edo ngwa ngwa. O nwere ike HDGD ike ma nwee ike ịmịcha mmiri iji zaa ma mepụta ngwọta callodal. Nke a na - eme HPMC ebe a na - ejikarị ya na ndị dị omimi, na - ekwu okwu, ndị irolfiers na ọrụ ndị ọzọ, karịsịa na ụlọ ọrụ nri.
N'ime ụlọ ọrụ ọgwụ, a na-ejikarị HPMC na-ejikarị nhazi ọgwụ na-akwado ọgwụ, nke nwere ike ijikwa nke ọma ijikwa ọgwụ ọgwụ. Ihe solubality na hydre na-enyere ya aka igbari na eriri afọ, jiri nwayọ na-edepụta ọgwụ ọjọọ, ma mee ka nrụpụta ọgwụ ike.
3. Ndị na-eme mkpọtụ na ihe
Akụkụ dị mma nke HPMC na-emekarị. Viccosity of HPMC Ngwọta nwere njikọ chiri anya na ntinye ya, ogo molecular na ogo hydration. Ihe ngwọta dị elu molecular nwere nnukwu viscosity ma dị mma maka ngwa ọ bụla chọrọ visations dị elu, dịka adhesives, mkpuchi, wdg.
HPMC nwekwara Njirimara Gells. Mgbe ịta nke HPMC Ngwọta dị elu, ọ nwere ike ịkpụzi gel, nke dị ezigbo mkpa na ọgwụ, ọkachasị na ọgwụ na-atọ ụtọ.
4. Njirimara na Njirimara antioxidant
HPMC nwere ezigbo kemịkal ma nwee ike ịnagide ọtụtụ ụkpụrụ plọ dị iche iche (n'ozuzu 4 ruo 10). Ya mere, ọ nwere ike idobe ihe owuwu ya na ọtụtụ acid na alkaline dị iche iche. E jiri ya tụnyere ihe ndị ọzọ cellulose, Hpmc nwere akụrụngwa na-ahụ anya na-ahụkarị ma enwere ike iji usoro nchekwa ogologo oge.
Uzo kemịkal a na-eme ka Hpmc mee ihe n'ọtụtụ nri, ihe ịchọ mma na ọgwụ ọgwụ. Dịka ọmụmaatụ, na ụlọ ọrụ nri, a na-eji HPMC mee ihe dị ka emulsifier na Treshener iji melite udidi na nkwụsi ike nke ngwaahịa a.
5. Biotom na Nchekwa
HPMC, dị ka polymer na-agbanye mmiri, nwere nnukwu biocom dị ma ọ bụ na-ejikarị ya na ọgwụ, nri na ụlọ ọrụ ịchọ mma. A naghị etinye aka HPMC kpamkpam n'ime ahụ, kama dị ka eriri nri, ọ na-awụnye site na nri nri ma na-ewere ihe na-adịghị mma na-enweghị isi na nke na-enweghị isi na nke na-adịghị mma. A na-ejikarị ya arụ ọrụ na sistemụ nnyefe ọgwụ iji nyere aka ịgha ọgwụ na nke nwayọ.
Dịka nri nri nri, nke Codex Acrarius nyere ọrụ dị ka ihe dị mma maka iji ya. A na-ahụta ngwa ya na ahụike mmadụ na-adịghị emerụ ahụ.
6. Ugbo ala
6.1 Omuma ahia ahia
Na nkwadebe ọgwụ, a na-eji HPMC mee ihe dị ka nke na-eto eto, emulsifier, kwụsie ike na-ebu ya. Na usoro onunu ogwu nke onu, a na-ejikarị HPMC na capsules, mbadamba na nkwadebe ma ọ bụ nnapụta. N'ihi ezigbo biocom dị mma na akụrụngwa na-edozigharị, a na-eji HPMC kwadebe ndị na-ebu ọgwụ ọjọọ, ọkachasị na mmepe nke ọgwụ ọjọọ.
6.2 ụlọ ọrụ nri nri
Na ụlọ ọrụ nri, a na-eji HPMC mee ihe maka oke, njigide, emulsification, ihe nkiri na akụkụ ndị ọzọ. A na-ejikarị ya na ngwongwo ndị a na-eme achịcha, ihe oriri, nri oyi, nke dị njikere nri na sauces. HPMC nwere ike ime ka uto na ederede nri ma gbasaa ndu nri.
6.3 Nchoputa na nlekọta onwe onye
Na mpaghara Cosmetics, a na-ejikarị HPMC dị ka nke na-eme na ememme na ngwaahịa nlekọta anụ ahụ, ncha, ịsa ahụ na ngwaahịa ndị ọzọ. O nwere ezigbo anụ ahụ dị mma, nwere ike melite nguzozi na nkwụsi ike nke ngwaahịa ahụ, ọ dịghịkwa mfe iwepụ anụahụ n'oge.
6.4 Ewu na ngwa ọrụ
N'ime ụlọ ọrụ owuwu, a na-eji HPMC mee ihe dị ka nke na-ewu ewu dị ka cent ciment, taments, tamessive, na mkpuchi mgbidi. Ọ nwere ike melite arụ ọrụ na mmiri n'oge owuwu, mee ka ndọnye akụrụngwa mee ihe, ma melite ike na ịdị ogologo mgbe ihicha.
Dị ka polymer dị mkpa, HPMC nwere ọtụtụ anụ arụ na kemịkal dị mma, dị ka ezigbo mmiri solbality, na-emekwa, nkwụsi ike na biochom. Ngwa ya gụnyere ọgwụ, nri, ihe ịchọ mma, owuwu na ọrụ ndị ọzọ, na-enye ọrụ Silynergic ọrụ maka ngwaahịa na ubi ndị a. N'ọdịnihu, dị ka ndị mmadụ chọrọ maka gburugburu ebe obibi nwere ahụike na arụmọrụ na-aga n'ihu na-abawanye, atụmanya ngwa nke HPMC ga-aba ụba.
