HydroxyPropyl methylcellse (HPMC) ni igice cya kabiri, iner, gukosora amazi yakoreshejwe cyane munganda nko kuvura, ibiryo, kwisiga no kubaka ibikoresho. Umubano hagati yuburemere bwa molecular hamwe nubwato bugira ingaruka zikomeye kumikorere yayo muburyo butandukanye.
1.. Kubantu bake cyane hamwe na firime
Uruzinduko rwa HPMC rugira ingaruka ku buryo butaziguye mu mazi. HPMC ifite ubushyuhe bwo hasi irashobora gushonga mumazi byihuse kandi bikora igisubizo gifatika kandi kimwe, kikaba gikwiye kubisabwa gutatanya byihuse, nkibi binyobwa byihuse cyangwa imiti yihuse cyangwa imiti ihita. HPMC ifite ubushyuhe bwo hejuru busaba igihe kirekire cyo gusebanya, ariko irashobora gutanga filisiyo nziza nimbaraga mugihe bikwiranye na firime, niko bikwiranye na tablet yo gutwika, kuri firime yo kurinda matrix mu myiteguro irambye.
2. Guhagarara no kumeneka
HPMC hamwe na viscosity yo hejuru mubisanzwe ifite umutekano ukomeye no gukomera. Kurugero, iyo bikoreshejwe nkumubyimba wa sima cyangwa ibikomoka kuri gypsum mubikoresho byo kubaka, viscosity stcosity yo kugumana namazi no kurwanya SAG, gufasha kwagura igihe cyo kubaka no kugabanya gukata. Mu nganda za farumasi, high-viscosity HPMC ikoreshwa mu kugenzura igipimo cyo kurekura ibiyobyabwenge. Imyitozo yo hejuru yemerera ibiyobyabwenge kurekurwa buhoro buhoro mumubiri kandi biteza imbere ibinyabuzima bya bioakwaiLaulity.
3. Guhagarikwa no kuzenguruka
Impinduka muri viscosity nayo igira ingaruka kumitungo yahagaritswe na edulis ya HPMC. Kubera urunigi rugufi rwa molecula, rubanda-ruto HPMC ibereye gukoreshwa nkuwagejejweho. Irashobora guhagarika neza ibice bidasubirwaho mubiyobyabwenge no kwirinda imvura. HPMC ifite ubushyuhe bwinshi burashobora gukora imiterere ikomeye mubisubizo kubera urunigi rwayo ndende, niko gukora neza muburyo butuje kandi bushobora gukomeza guhuriza hamwe.
4. Rheologiya no gusaba ibintu
Ibintu byerekeranye na HPMC nabyo ni ikintu cyingenzi cyatewe na viscosiya. Isushi-hasi hpmc ibisubizo byerekana amazi meza, biroroshye gutera no gusaba, kandi akenshi bikoreshwa mubicuruzwa byita kuruhu no gushushanya. Umuti ukabije hpmc igisubizo cyitwaye nkinyamanswa itari nshya kandi ifite ibintu byoroshye. Ibi biranga bituma HPMC yoroshye kuri HPMC yoroshye gukora munsi yimiterere miremire, mugihe ukomeje kuba vicosi ndende mubihe byihutirwa, bityo bigatuma filme-ishishikarizwa kandi ituze kubicuruzwa.
5. Ingero zo gusaba
Umurima wa farumasi: HPMC yo hasi HPMC (nka CPS 50) ikunze gukoreshwa mugukora ibiyobyabwenge byihuse kugirango hamenyekane ibiyobyabwenge byihuse kugirango hamenyekane ibiyobyabwenge byihuse kugirango hamenyekane ibiyobyabwenge byihuse kugirango hamenyekane ibiyobyabwenge byihuse kugirango hamenyekane ibiyobyabwenge byihuse kugirango hamenyekane ibiyobyabwenge byihuse kugirango hamenyekane ibiyobyabwenge byihuse. Nka 4000 CPMC (nka 4000 CPS) irekura ibinini bihamye kugirango uhindure Igipimo cyo kurekura ibiyobyabwenge.
Umwanya w'ibiribwa: Mu binyobwa ako kanya, HPMSIty HPMC irashobora gushonga vuba adatsinzwe; Mu bicuruzwa bitetse, viscosity-subcosity HPMC irashobora guteza imbere amazi yo gukora ifu kandi akazamura uburyohe hamwe nibiranga ibicuruzwa byatetse.
Umwanya wubwubatsi: Mu gushishikarizwa no kurera, viso-vitcosity HPMC yorohereza kubaka kandi itezimbere imikorere myiza; Mugihe HPMC yo hejuru HPMC yongera umubyimba na sag kurwanya ifiriti.
Ibyerekanwe bya HPMC ni parameter yingenzi igena imikorere yayo mubisabwa. Ubu buryo buke bwa HPMC isanzwe ikoreshwa aho gusenya byihuse hamwe nimbwa bisabwa, mugihe ubushyuhe bwinshi bwa HPMC bukoreshwa neza muri porogaramu isaba adsionion, gushiraho firime nziza no gutuza. Kubwibyo, guhitamo HPMC hamwe na viscosity iburyo ningirakamaro kugirango utegure imikorere yayo mumirima itandukanye.
