Hydroxypropyl methylcellulose (HPMC) ni selile ya ionic selulose ether ifite imirimo myinshi hamwe nurwego runini rwa porogaramu.
1. Ibikoresho byo kubaka
Mu nganda zubaka, HPMC ikoreshwa cyane mubicuruzwa nka sima ya sima, ibikoresho bishingiye kuri gypsumu, ifu ya putty hamwe na tile. Ibikorwa byayo byingenzi birimo:
Kubika amazi: HPMC irashobora guteza imbere cyane gufata amazi ya minisiteri no kubuza amazi guhumeka vuba, bityo bigatuma imikorere yubwubatsi igira ingaruka nziza.
Kubyimba no gusiga: Birashobora kongera ubukana n'amazi ya minisiteri, bigatuma ubwubatsi bworoha kandi bikagabanya kwambara kw'ibikoresho byo kubaka.
Kurwanya gucamo: Mu kunoza uburyo bwo gufata amazi no gufatira minisiteri, HPMC irashobora gukumira neza minisiteri na plaster guturika mugihe cyo gukira.
2. Kwambika amarangi
Mu nganda zo gusiga amarangi no gutwikira, HPMC ikoreshwa nkibyimbye, emulifier na stabilisateur. Mu bikorwa byayo harimo:
Kubyimba: Ongera ubwiza bwirangi, wirinde kugabanuka, no kunoza uburinganire.
Igihagararo: Ifasha kugumya gukwirakwiza pigment hamwe nuzuza, kurinda gutuza no gusiba.
Kurwanya anti-sag: Kunoza imikorere yo gusiga irangi no kwirinda kugabanuka no gutonyanga.
3. Imiti n'ibiribwa
Mu nganda zimiti n’ibiribwa, HPMC ikoreshwa cyane mu bisate, capsules hamwe n’inyongeramusaruro. Imikorere yayo niyi ikurikira:
Ipitingi ya tableti: Nibikoresho bisize ibinini, HPMC irashobora kugenzura irekurwa ryibiyobyabwenge kandi ikarinda imiti ububobere na ogisijeni.
Igikonoshwa cya capsule: HPMC ningingo nyamukuru ya capsules yibikomoka ku bimera, ibereye ibikomoka ku bimera n’abantu allergic kuri capsules ikomoka ku nyamaswa.
Inkoko hamwe na emulisiferi: Mu biryo, HPMC ikoreshwa nkibyimbye, emulisiferi na stabilisateur kugirango itezimbere uburyohe nuburyohe bwibiryo.
4. Amavuta yo kwisiga
Mu nganda zo kwisiga, HPMC ikoreshwa mubicuruzwa nka amavuta yo kwisiga, amavuta, shampo hamwe nu menyo. Ibikorwa byayo byingenzi birimo:
Kubyimba: Itanga ubwiza bwiza kandi buhoraho, bigatuma ibicuruzwa byoroha kubishyira no kubyakira.
Imiterere yo gukora firime: Kora firime ikingira mucyo kugirango yongere imbaraga zuruhu.
Emulisation na Stabilisation: Ifasha kwigana no guhagarika imvange yamavuta yamazi kugirango wirinde gutandukana.
5. Ibindi bikorwa
HPMC ikoreshwa no mubindi bice byinshi nka:
Irangi ryo gucapa: Gukora nkibyimbye na stabilisateur kugirango ubuziranenge bwo gucapa.
Ubuhinzi: Bikoreshwa mu guhuza imbuto hamwe nudukoko twangiza udukoko mu buhinzi hagamijwe kunoza umusaruro no kumera kwimbuto.
Imyenda: Ikoreshwa mugucapura imyenda no gusiga irangi kugirango tunoze ubuziranenge bwo gucapa no kwihuta kwamabara.
6. Ibiranga inyungu
HPMC igira uruhare runini mu nganda zitandukanye bitewe n’imiterere yihariye y’umubiri n’imiti. Ibyingenzi byingenzi birimo:
Amazi meza: HPMC irashobora gushonga vuba mumazi akonje cyangwa ashyushye kugirango ikore igisubizo kiboneye.
Biocompatibilité n'umutekano: HPMC ntabwo ari uburozi kandi ntacyo itwaye, ifite biocompatibilité nziza, kandi ikoreshwa cyane mubiribwa na farumasi.
Igihagararo: Irwanya aside, alkalis nu munyu, ifite ituze ryiza kandi irashobora gukomeza imikorere yayo mubidukikije bitandukanye.
Hydroxypropyl methylcellulose ikoreshwa cyane mubwubatsi, gutwikira, imiti, ibiryo, kwisiga no mu zindi nganda bitewe nuburyo bwinshi kandi bukora neza. Imikorere yacyo yo kubyimba, kubika amazi, emulisation no gutuza bituma iba ikintu cyingenzi mubicuruzwa bitandukanye, itanga umusanzu wingenzi mugutezimbere imikorere yuburambe hamwe nuburambe bwabakoresha.
