HydroxyPropyl MethylcellllALese (HPMC) ni polymer yo mu mibereho myinshi ifite ikoreshwa mu nganda zinyuranye nk'ibiyobyabwenge, kubaka, ibiryo, ibiryo, ibiryo, ibiryo bigira akamaro mu bicuruzwa byinshi. Dore ubushakashatsi bwimbitse bwa HPMC:
1. Ibiranga HPMC:
Imiterere yimiti: HPMC ikomoka kuri selile, polymer karemano iboneka mubimera. Birakoreshwa na selile ihindura selile hamwe na proplene okiside na methyl chloride. Urwego rwo gusimbuza HydroxyProppopyl na Methoxy amatsinda agena imitungo yayo.
Gukemurwa: HPMC irashonje mumazi hejuru yubushyuhe bwinshi. Gukundwa biterwa nurwego rwo gusimbuza nuburemere bwa molekiro bwa polymer. Urwego rwo gusimbuza hejuru ruganisha ku kongera amazi.
IYI VISCOSIty: HPMC yerekana imyitwarire ya pseudoplastique cyangwa inanga yoroheje, bivuze ko ubukuru bwayo bugabanuka munsi yimihangayiko. Ibyamamare bya HPMC Ibisubizo bya HPMC birashobora guhinduka muguhindura ibipimo nkuburemere bwa molecular, urwego rwo gusimbuza, no kwibanda.
Gushiraho firime: HPMC ikora firime zisobanutse kandi byoroshye mugihe uva mubisubizo. Ibiranga filime birashobora guhindurwa no guhindura Polymer kwibanda no kubaho kwa plastistizers.
Umutekano mu bushyuhe: HPMC ifite umutekano mwiza, hamwe nubushyuhe bwo kubora mubisanzwe biri hejuru ya 200 ° C. Ibi bituma bikwirakwira muburyo butandukanye bwo gutunganya, harimo gushonga hashyushye no gutemba.
Hydrophility: Bitewe na hature ya hydhilic, HPMC irashobora gukurura no kugumana amazi menshi. Uyu mutungo ni mwiza mubisabwa nko kugenzurwa-kurekura ibiyobyabwenge kandi nkumukozi wijimye muri sisitemu ya equeous.
Guhuza: HPMC irahuye nibindi bikoresho bitandukanye, harimo nabandi polymers, plastistizers, nibikoresho bifatika bya farumasi (APIS). Iyi guhuza yemerera sisitemu igoye gushyirwaho ibintu byihariye.
Ibintu bitari ngombwa: HPMC ni polymer itari polymer, bivuze ko idatwara amafaranga ayo ari yo yose. Uyu mutungo ugabanya imikoranire hamwe n'amoko yishyurwa muri forelation kandi yongerera umutekano wacyo mu gisubizo.
2.Imikorere ya 2.HPMC:
Bunders: Muri Tablet forems, HPMC ikora nkumuhuzabikorwa, uteza imbere guhinduranya hagati yibice no kongera imbaraga zamashini za tablet. Ifasha kandi ibinini bisenyuka nyuma yo kwinjizwa.
IHURIRO RY'IMISOLI: HPMC ikoreshwa cyane nk'umukozi wo gutoranya film ku bisate na capsules. Ikora ikariso imwe, ikingira ikubiyemo uburyohe hamwe nimpumuro yibiyobyabwenge, ikura, kandi yorohereza kumira.
Gusohora: HPMC irashobora gukoreshwa mugukemura igipimo cyo kurekura ibiyobyabwenge mumiterere ya farumasi. Na Hydrating kugirango akore gel layer, HPMC irashobora gutinza kurekurwa no gutanga ingaruka zikomeje.
Guhindura vicosiire: muri sisitemu yo mu mazi, HPMC ikora nka virusire cyangwa uburebure. Itanga imyitwarire ya pseudopplastique ya pseudopplastique, itezimbere ituze hamwe nibikorwa byo gusaba ibikoresho nka cream, amavuta na gels.
Guhagarika umukozi: HPMC ikoreshwa muguhagarika guhagarikwa kubice bidafite ishingiro muburyo bwamazi. Irinda gutura mu kongera vicosity yicyiciro cyicyiciro gihoraho no kuzamura ibice.
EmulsiFier: Muri Emulsions, HPMC igaburira Imigaragarire iri hagati yicyiciro cyamavuta n'amazi, kubuza gutandukana no gutandukana. Itezimbere ubuzima nubuzima bwibintu byo guhanga amasoko nka cream, amavuta no kwisiga.
Imiterere ya Hydrogel: HPMC irashobora gukora hydrogels mugihe ya hydrated, bigatuma ari ingirakamaro mumyambarire yakomeretse, hamagara lens, hamwe na sisitemu yo gutanga ibiyobyabwenge. Izi Hydrogels zitanga ahantu hashyushye gukiza kandi birashobora gupakirwa nibiyobyabwenge kubitangwaho.
Umukozi wijuriye: HPMC ikoreshwa nkumukozi wijimye mubicuruzwa nkibisasu, imyambarire n'ibiribwa. Itanga imiterere yoroshye kandi yongerera uburyohe nta guhindura uburyohe cyangwa ibintu byimirire.
Inyongerakwa: Mu nganda zubwubatsi, HPMC ikoreshwa nk'abakozi bagumana amazi mu mico ya sima ishingiye ku bapadiri. Itezimbere imikorere, kumeneka, no kugabanya gucana no gutinda amazi.
Guhindura hejuru: HPMC irashobora guhindura imitungo yo hejuru ya disikuru nkuru nkimpapuro, imyambarire namanyabe. Itezimbere Icapiro, Gusohora hamwe ninzitizi bya Coatings na Filime.
HydroxyPropylmethylcellcellCellCellsells (HPMC) ni polymer itandukanye ifite imitungo n'imikorere itandukanye. Kudakemukira, viscosity, ubushobozi bwo gushinga filime hamwe no guhuza ibishoboka byose muburyo bukoreshwa muburyo bwinshi mu nganda. Kuva kuri farumasi yo kubaka, ibiryo byo kwisiga, HPMC ikomeje kugira uruhare runini mugutezimbere ibicuruzwa nubuziranenge. Nk'ikoranabuhanga n'ikoranabuhanga, guhinduranya no gukoresha HPMC birashobora gukomeza kwaguka, guhanga udushya mu rwego rwo gushyiraho no guteza imbere ibicuruzwa.
