Hydroxypylmethylcelllose (HPMC) bụ ihe eji egbu egbu na-ejikarị n'ọtụtụ ụlọ ọrụ, gụnyere ọgwụ, owuwu na nri. Nta ya nwere ike ịdị iche iche dabere na ihe ndị dị ka ogo molecular ya, ogo nke nnọchi anya, na ntinye uche.
Okwu Mmalite na Hydropyythylthylthyllllose (HPMC)
Hydroxypyl Methylcellose bụ polymetik polymetik nwetara site na ngbanwe kemịkal nke cellose. N'ihi ihe pụrụ iche ya, a na-ejikarị ya dị ka nke na-eme nke ọma, onye na-edebe ihe nkiri mbụ, ihe nkiri gara aga na ngwa agha.
Ihe owuwu molular na mejupụtara
HPMC nwere ndị mejupụtara bakilose badbone na hydroxypyl na ndị isi Methoxy. Ogo nke dochie anya (DS) na-ezo aka na ọnụ ọgụgụ nke ebe a na-ejikọkarị otu na cellulose. Uru DS a kapịrị ọnụ na-emetụta akụrụngwa anụ ahụ na kemịkal nke HPMC.
HPMC viscosity
Visaty bụ ihe dị mkpa maka HPMC, ọkachasị na ngwa na-eji ndị na-eme mkpọtụ na akụrụngwa.
Ọ bụ ihe kpatara nsogbu na-emetụta viscs ngwọta site na ọtụtụ ihe ndị:
1.
Ibu akwara nke Hpmc na-emetụta viscosity ya. Na mkpokọta, oke molecular dị elu na-eme ka azịza viscosis dị elu. Enwere akara mmụta dị iche nke HPMC na ahịa, onye ọ bụla nwere nke ya nke ọma.
2. Afọ nke nbanye (DS)
The DS ụkpụrụ nke hydropyyl na ndị otu methoxy na-emetụta solubaty na viscosity nke HPMC. Vskpụrụ dị elu Ds n'ozuzu na-eme ka ụba mmiri na edozi oke.
3. Ileba anya
Nta nke hpmc na ngwọta bụ ihe dị mkpa na-emetụta viscosity. Dịka ịta na-abawanye, viscosis na-abawanye. A na-akọwakarị mmekọrịta a site na nhata nke Krigerherty.
4. Okpomoku
Ọnọdụ okpomọkụ na-emetụtakwa viscosity nke HPMC. N'ikwu okwu, vissethse mbelata dị ka ọnọdụ okpomọkụ na-abawanye.
Ebe ngwa
A na-ejikarị HPMC, gụnyere mbadamba ọgwụ, gụnyere mbadamba na ngwọta na ngwọta na-achịkwa onwe gị dị oke mkpa.
Ihe owuwu: N'obere ụlọ ọrụ owuwu, a na-eji HPMC mee ihe dị ka onye na-eme ihe na ngwaahịa ciment iji kwalite ike ọrụ na njigide mmiri.
Industrylọ ọrụ nri: A na-eji HPMC mee ihe dị ka nke ukwu, kwụsie ike na emulsifier na ngwa nri.
Nga mbara nke hydroxyl Methylcellose bụ ihe dị mgbagwoju anya na-emetụta ọtụtụ ihe ndị dị ka ibu molecular, ogo nke nnọchi anya, itinye uche na ọnọdụ okpomọkụ. Agesdị akara dị iche iche nke HPMC dị mma maka ngwa ndị akọwapụtara, na ndị na-emepụta na-enye ọnụ ọgụgụ data na-akọwapụta viccosise nke ọkwa ọ bụla n'okpuru ọnọdụ dị iche iche. Ndị na-eme nchọpụta na ndị na-ewepụta ihe kwesịrị ịtụle ihe ndị a ka hazie Njirimara nke HPMC iji mezuo ihe ha chọrọ.
