Ingaruka yubushyuhe kuri Hydroxypropyl Methyl Cellulose
Hydroxypropylmethylcellulose, izwi kandi ku izina rya HPMC, ni polymer ikoreshwa cyane mu nganda zitandukanye nka farumasi, amavuta yo kwisiga, n'ibiribwa. Guhindura byinshi bituma ihitamo gukundwa kubikorwa byinshi. Kimwe mu bintu bigira ingaruka kumikorere ya HPMC ni ubushyuhe. Ingaruka yubushyuhe kuri HPMC irashobora kuba nziza cyangwa mbi, bitewe nuburyo bwo gukoresha. Muri iki kiganiro, turasesengura ingaruka zubushyuhe kuri HPMCs kandi dutanga icyerekezo cyiza kuriyi ngingo.
Icyambere, reka twumve HPMC icyo aricyo nuburyo ikorwa. HPMC ni selulose ether ikomoka muburyo bwo guhindura imiti ya selile. Ni ifu yera cyangwa itari yera, impumuro nziza, uburyohe kandi ntabwo ari uburozi. HPMC ifite amazi meza, kandi ubwiza bwayo hamwe na gel birashobora guhinduka ukurikije urugero rwo gusimbuza nuburemere bwa molekile ya polymer. Ni polymer idasanzwe kandi ntabwo ikora hamwe nimiti myinshi.
Ubushyuhe ni ikintu cyingenzi kigira ingaruka kumikorere ya HPMC. Irashobora kugira ingaruka kuri solubilité, viscosity na gel imiterere ya HPMC. Muri rusange, kwiyongera k'ubushyuhe bituma kugabanuka kwijimye ryumuti wa HPMC. Iyi phenomenon iterwa no kugabanuka kwa hydrogène hagati ya molekile ya polymer uko ubushyuhe bwiyongera, bigatuma imikoranire hagati yiminyururu ya HPMC igabanuka. Amatsinda ya hydrophilique kumurongo wa polymer atangira gukorana cyane na molekile zamazi kandi bigashonga vuba, bigatuma kugabanuka kwijimye.
Nyamara, ku bushyuhe buke, HPMC irashobora gukora geles. Ubushyuhe bwa gelation buratandukanye ukurikije urugero rwo gusimbuza nuburemere bwa molekuline ya polymer. Ku bushyuhe bwo hejuru, imiterere ya gel igenda igabanuka kandi ntigihamye. Nubwo, ubushyuhe buke, imiterere ya gel irakomeye kugirango ihangane nihungabana ryo hanze kandi igumane imiterere na nyuma yo gukonja.
Rimwe na rimwe, ingaruka z'ubushyuhe kuri HPMC zirashobora kuba ingirakamaro, cyane cyane mu nganda zimiti. HPMC isanzwe ikoreshwa nkibikoresho bya farumasi, nkibihuza, bidahwitse, na matrix irekura. Kuburyo bwagutse-burekura, ibiyobyabwenge birekurwa buhoro buhoro muri materix ya HPMC mugihe, bitanga kugenzurwa kandi igihe kirekire. Igipimo cyo kurekura cyiyongera hamwe nubushyuhe, butuma ibikorwa byihuse byo kuvura, byifuzwa mubihe bimwe.
Usibye uruganda rukora imiti, HPMC ikoreshwa cyane mu nganda z’ibiribwa nkibyimbye, emulisiferi na stabilisateur. Mugukoresha ibiryo, ubushyuhe nibintu byingenzi mugutegura. Kurugero, mugukora ice cream, HPMC irashobora gukoreshwa muguhagarika emulisiyo no gukumira ikura rya kirisita. Ku bushyuhe buke, HPMC irashobora gukora gel, ikuzuza icyuho cyose cyumwuka kugirango ice cream ihamye hamwe nuburyo bworoshye.
Mubyongeyeho, HPMC nayo ikoreshwa mugutegura ibicuruzwa bitetse. HPMC irashobora kunoza ubwinshi nubunini bwumugati mukongera ubushobozi bwo gufata amazi yifu. Ubushyuhe burashobora kugira ingaruka zikomeye mugukora imigati. Mugihe cyo guteka, ubushyuhe bwifu bwiyongera, bigatuma HPMC ishonga kandi ikwirakwira. Ibi na byo byongera viscoelasticitike yifu, bikavamo umutsima ukomeye, woroshye.
Muncamake, ingaruka yubushyuhe kuri HPMCs nikintu kigoye gitandukana ukurikije porogaramu yihariye. Muri rusange, kwiyongera kwubushyuhe bituma kugabanuka kwijimye, mugihe igabanuka ryubushyuhe ritera gelation. Mu nganda zimiti, ubushyuhe burashobora kongera irekurwa ryimiti igenzurwa, mugihe mubiribwa byibiribwa, HPMC irashobora guhagarika emulisiyo, ikarinda ibara rya kirisita, kandi igateza imbere ibicuruzwa bitetse. Kubwibyo, ingaruka yubushyuhe kuri HPMC igomba kwitabwaho muguhitamo no gukoresha polymers kugirango ugere kubisubizo byifuzwa.
