1. Intangiriro
Hydroxypropyl methylcellulose (HPMC) ningirakamaro ya selile ya selile ikoreshwa cyane mubikoresho byubwubatsi, gutegura imiti, inyongeramusaruro hamwe no kwisiga. Kubika amazi meza nimwe mubintu byingenzi biranga HPMC mugari.
2. Imiterere n'imiterere ya HPMC
2.1 Imiterere yimiti
HPMC ni igice cya sintetike ya selile ya ether. Hydroxypropyl na methyl insimburangingo muburyo bwa chimique itanga imbaraga zidasanzwe hamwe na colloidal. Imiterere shingiro ya HPMC igizwe na β-D-glucose iminyururu ya selile, aho amatsinda amwe ya hydroxyl asimburwa na methyl na hydroxypropyl. Umwanya n'urwego rwo gusimbuza ibyo bisimbura bigira ingaruka ku buryo butaziguye, gukomera no gufata amazi ya HPMC.
2.2 Imiterere yumubiri
Amazi meza: HPMC irashobora gushonga byoroshye mumazi akonje kandi ikora igisubizo cya colloidal mumazi ashyushye.
Umubyibuho ukabije: Irashobora gukora igisubizo kiboneka mumazi kandi ikagira ingaruka nziza.
Umutungo ukora firime: Irashobora gukora firime iboneye kandi yoroheje.
Guhagarikwa: Ifite imikorere myiza yo guhagarika igisubizo kandi irashobora guhagarika ibintu byahagaritswe.
3. Kubika amazi ya HPMC
3.1 Uburyo bwo gufata amazi
Kugumana amazi ya HPMC biterwa ahanini n’imikoranire hagati ya hydroxyl nitsinda risimburana mumiterere ya molekile na molekile zamazi. By'umwihariko, HPMC igumana amazi binyuze mu buryo bukurikira:
Guhuza hydrogène: Amatsinda ya hydroxyl muri molekile ya HPMC akora hydrogène hamwe na molekile zamazi. Izi mbaraga zifasha molekile zamazi guhambirwa hafi ya HPMC, bikagabanya guhumeka kwamazi.
Ingaruka yo kwijimisha cyane: Umuti mwinshi wijimye wakozwe na HPMC mumazi urashobora kubangamira kugenda kwamazi, bityo kugabanya amazi.
Imiterere y'urusobe: Imiterere y'urusobe rwakozwe na HPMC mumazi irashobora gufata no kugumana molekile zamazi, kuburyo amazi yagabanijwe neza murwego rwurusobe.
Ingaruka ya colloid: Koloide yakozwe na HPMC irashobora gufunga amazi imbere ya koleo kandi ikongera igihe cyo gufata amazi.
3.2 Ibintu bigira ingaruka ku gufata amazi
Impamyabumenyi yo gusimbuza: Kubika amazi ya HPMC bigira ingaruka ku rwego rwo gusimbuza (DS). Urwego rwo hejuru rusimburwa, hydrophilicity ya HPMC niko ikora neza.
Uburemere bwa molekuline: Uburemere buke bwa molekuline bufasha gukora urusobe rukomeye rwa molekile, bityo bigatuma amazi agumana.
Kwishyira hamwe: Ubwinshi bwumuti wa HPMC bugira ingaruka zikomeye mukubungabunga amazi. Ibisubizo byibanze cyane birashobora gukora ibisubizo bigaragara neza hamwe numuyoboro uhamye, bityo bikagumana amazi menshi.
Ubushyuhe: Kubika amazi ya HPMC biratandukana n'ubushyuhe. Iyo ubushyuhe buzamutse, ubwiza bwumuti wa HPMC buragabanuka, bigatuma kugabanuka kwamazi kugabanuka.
4. Gukoresha HPMC mubice bitandukanye
4.1 Ibikoresho byo kubaka
Mu bikoresho byo kubaka, HPMC ikoreshwa nk'igumana amazi ya sima n'ibicuruzwa bishingiye kuri gypsumu. Ibikorwa byayo byingenzi birimo:
Kunoza imikorere yubwubatsi: Mugukomeza ubushuhe bukwiye, igihe cyo gufungura sima na gypsumu cyongerewe, bigatuma inzira yo kubaka yoroshye.
Kugabanya ibice: Kubika amazi meza bifasha kugabanya ibice byabyaye mugihe cyo kumisha kandi bizamura imbaraga nigihe kirekire cyibikoresho byanyuma.
Kunoza imbaraga zububiko: Muri tile yifata, HPMC irashobora kongera imbaraga zumubano no kuzamura ingaruka.
4.2 Imyiteguro ya farumasi
Mu myiteguro ya farumasi, kubika amazi ya HPMC bigira uruhare runini mukurekura no gutuza kwimiti:
Imyiteguro irambye-irekura: HPMC irashobora gukoreshwa nka matrike irekura-irekura imiti kugirango igere ku irekurwa rirambye ryibiyobyabwenge hifashishijwe kugenzura amazi yinjira nigipimo cy’ibiyobyabwenge.
Thickeners and binders: Mu biyobyabwenge n’ibinini, HPMC ikora nk'ibyimbye kandi bihuza kugira ngo ibiyobyabwenge bigumane kandi bihamye.
4.3
Mu nganda z’ibiribwa, HPMC ikora nk'ibyimbye kandi ikomeza, kandi kubika amazi bikoreshwa kuri:
Kunoza uburyohe: Binyuze mu gufata amazi, HPMC irashobora kunoza uburyohe nuburyohe bwibiryo, bigatuma bisiga amavuta kandi biryoshye.
Kongera igihe cyo kuramba: Binyuze mu kubika amazi, HPMC irashobora gukumira gutakaza amazi mugihe cyo kubika, bityo ikongerera igihe cyo kubaho.
4.4 Amavuta yo kwisiga
Mu kwisiga, kubika amazi ya HPMC bikoreshwa kuri:
Ingaruka nziza: Nka moisurizer, HPMC irashobora gufasha gufunga ubuhehere hejuru yuruhu kandi bigatanga ingaruka zigihe kirekire.
Guhagarika ihagarikwa: Muri emulisiyo no guhagarikwa, HPMC ihindura ibicuruzwa kandi ikarinda ibyiciro no gutembera.
Kubika amazi ya HPMC bituma iba ibikoresho byingenzi mubikorwa byinshi. Igumana amazi kandi igabanya guhumeka kwamazi binyuze muri hydrogène ihuza, ingaruka zijimye cyane, imiterere y'urusobe n'ingaruka za colloid. Kubika amazi bigira ingaruka kurwego rwo gusimbuza, uburemere bwa molekile, kwibanda hamwe nubushyuhe, bigena imikorere ya HPMC mubisabwa byihariye. Haba mubikoresho byubwubatsi, imiti yimiti, inyongeramusaruro cyangwa kwisiga, kubika amazi HPMC bigira uruhare runini mukuzamura ubwiza nimikorere yibicuruzwa.
