Hydroxypropyl cellulose (HPC) bụ ọkara sịntetik, na-abụghị ionic, mmiri-soluble cellulose ewepụtara na ọtụtụ uru. A na-ejikarị ya eme ihe na ọgwụ, nri, ihe ịchọ mma, ihe ụlọ na ubi ndị ọzọ.
1. Ọmarịcha mmiri solubility
Hydroxypropyl cellulose na-agbaze nke ọma na ma mmiri oyi na mmiri ọkụ ma gbazee ngwa ngwa. Ọ nwere ike na-etolite a ike colloidal ngwọta na mmiri na adabara iji dị iche iche na ngwaahịa na-achọ mmiri solubility, dị ka ọgwụ preparations, nri mgbakwunye, wdg Nke a dị mma mmiri solubility na-eme ka ọ karịsịa bara uru na ọgwụ ụlọ ọrụ, karịsịa na siri ike dispersions. Mbadamba ụrọ na hydrogels na-achịkwa.
2. Ndị na-adịghị egbu egbu na ndị na-adịghị njọ, ezigbo biocompatibility
Hydroxypropyl cellulose bụ ihe na-adịghị egbu egbu na nke na-adịghị emerụ ahụ nke ejirila ọgwụ na nri mee ihe n'ọtụtụ ebe, na-egosipụta oke nchekwa ya. N'ebe a na-emepụta ọgwụ, HPC bụ ihe a na-ejikarị eme ihe na mkpuchi mbadamba, nrapado, disintegrants na stabilizers. Na mgbakwunye, HPC nwere ezigbo bioacompatibility yana ọ naghị ebute mmeghachi omume mgbochi ma ọ bụ nsi. Ya mere, a na-eji ya na ngwaahịa ndị dị ka ọgwụ anya, mbadamba ọnụ, capsules, na ọgwụ ndị dị n'elu.
3. Magburu onwe film-akpụ Njirimara
Hydroxypropyl cellulose nwere ezigbo ihe na-emepụta ihe nkiri ma nwee ike ịmepụta ihe nkiri na-enwu enwu, enweghị agba, na-agbanwe agbanwe ma kwụsie ike n'elu ihe. A na-eji ihe onwunwe a eme ihe n'ọtụtụ ebe na mpaghara ọgwụ na nri, karịsịa na mkpuchi nke mbadamba nkume iji gbochie mbadamba nkume site na mmiri, oxidation ma ọ bụ decomposition ọkụ. N'ubi nri, a na-eji HPC dị ka ihe nkiri oriri na-edozi ahụ iji chekwaa ịdị ọhụrụ, kewapụ ikuku na mmiri, na ịgbatị ndụ nri.
4. Ntọhapụ na-achịkwa na adhesion
Hydroxypropyl cellulose nwere ihe ntọhapụ a na-achịkwa nke ọma ma na-ejikarị ya n'ụdị usoro ntọhapụ a na-achịkwa na ụlọ ọrụ ọgwụ iji nyere ọgwụ aka ịtọhapụ nke ọma na nwayọọ nwayọọ n'ime ahụ. Adhesion ya na-enye ohere iji HPC mee ihe dị ka ihe nkpuchi na mbadamba nkume iji hụ na mbadamba nkume ndị ahụ na-eguzosi ike n'ezi ihe ma nwee isi ike kwesịrị ekwesị n'oge usoro mmepụta. Na mgbakwunye, HPC nwere ike welie adhesion nke ọgwụ na tract eriri afọ ma melite bioavailability nke ọgwụ ọjọọ.
5. Nkwụsi ike dị elu
Hydroxypropyl cellulose nwere ezigbo nkwụsi ike na ìhè, okpomọkụ na ikuku oxygen, n'ihi ya, ọ gaghị ere ngwa ngwa mgbe echekwara ya n'okpuru ọnọdụ nkịtị. Nkwụsi ike a dị elu na-enyere HPC aka ịnọgide na-arụ ọrụ ya n'oge nchekwa ogologo oge na ịgbatị ndụ ndụ nke ngwaahịa ahụ, nke dị mkpa karịsịa na ntinye nke ihe ịchọ mma na ngwaahịa ọgwụ.
6. Ezi rheological Njirimara na ndim mmetụta
HPC nwere ezigbo rheological Njirimara na enwere ike iji ya dị ka thickener na rheology modifier. A na-ejikarị ya eme ihe na mkpuchi, nri na ihe ịchọ mma. Dịka ọmụmaatụ, na ihe ịchọ mma, HPC nwere ike ịbawanye viscosity nke emulsions, gels ma ọ bụ pastes, ma melite ọdịdị na mmetụta nke ngwaahịa ahụ. Na ụlọ ọrụ nri, a na-eji HPC mee ihe dị ka emulsifier na stabilizer iji gbochie nkewa nke ihe oriri ma melite nkwụsi ike na uto nke nri.
7. Ngwa ngwa ngwa
N'ihi ọtụtụ uru ya, a na-eji hydroxypropyl cellulose eme ihe n'ọtụtụ ụlọ ọrụ:
Ụlọ ọrụ na-emepụta ọgwụ: ejiri mee ihe dị ka ihe nkedo, ihe na-agbasa, onye na-ekpuchi ihe na stabilizer na mbadamba nkume, capsules, na ụdị usoro ọgwụgwọ a na-achịkwa.
Ụlọ ọrụ nri: ejiri mee ihe dị ka ihe na-esi ísì, emulsifier na ihe nkiri oriri maka nri edozichara, ihe nchekwa na ngwaahịa emulsified.
Ụlọ ọrụ ịchọ mma: eji dị ka thickener na ihe nkiri mbụ, tinye ya na ude akpụkpọ anụ, ncha ntutu, lipstick na ngwaahịa ndị ọzọ iji melite udidi na nkwụsi ike nke ngwaahịa.
Ihe owuwu ụlọ: ejiri ya dị ka onye na-ekpuchi mmiri na mmiri na-eji ciment na ngwaahịa gypsum na-eme ka owuwu na nkwụsi ike nke ihe.
8. Nchekwa gburugburu ebe obibi
Hydroxypropyl cellulose bụ ihe na-emebi emebi nke na-adịghị emetọ gburugburu ebe obibi. Na gburugburu ala na mmiri, HPC nwere ike imebi site na microorganisms, n'ihi ya, ọ gaghị eme ka mmetọ gburugburu ebe obibi dị ogologo oge mgbe ejiri ya mee ihe na ihe owuwu ụlọ, ihe nkwakọ ngwaahịa na ubi ndị ọzọ, nke na-egbo mkpa nke ụlọ ọrụ ọgbara ọhụrụ maka ihe omume enyi na gburugburu ebe obibi.
9. Ezigbo nguzogide na nkwụsi ike
Hydroxypropyl cellulose nwere ụfọdụ ogo nke ntu oyi na-eguzogide ma ka nwere ike ịnọgide na-enwe solubility na viscosity na obere okpomọkụ, nke na-enyere ya aka ịnọgide na-enwe ezigbo ngwa ngwa n'okpuru oké oyi ọnọdụ. Na mgbakwunye, HPC kwụsiri ike n'oge okirikiri oyi-ajụjụ na ọ naghị adị mfe mmiri ozuzo ma ọ bụ stratification. Ọ dị mma karịsịa maka ngwaahịa ndị dị mkpa ka echekwa ma ọ bụ jiri n'okpuru ọnọdụ okpomọkụ dị ala.
10. Ezi arụmọrụ nhazi
HPC nwere ezigbo mmiri na-agwakọta ihe n'oge nhazi, enwere ike ịgwakọta ya na ihe ndị ọzọ ngwa ngwa ma mee ya site na usoro nhazi dị iche iche dị ka extrusion, tableting, na spraying. N'ime ụlọ ọrụ na-emepụta ọgwụ, ọ bụ ihe na-eme ka ọ dị mfe nhazi nke nwere ike imeziwanye mmepụta ọgwụ na-emepụta ọgwụ ma belata ụgwọ ọrụ.
Hydroxypropyl cellulose aghọwo ihe dị mkpa na ihe dị mkpa n'ọtụtụ ụlọ ọrụ n'ihi mma mmiri ya dị mma, ihe na-emepụta ihe nkiri, adhesion, ntọhapụ na-achịkwa na biocompatibility. Karịsịa n'ime ụlọ ọrụ ọgwụ, nri na ihe ịchọ mma, ntụgharị na nchekwa nke HPC na-eme ka ọ bụrụ ihe kacha amasị. Site na mmepe nke sayensị na teknụzụ, ngwa ngwa nke HPC ga-aga n'ihu na-abawanye, na ọchịchọ ahịa ya n'ọdịnihu na ikike mmepe ga-aga n'ihu na-eto eto.
