Hydroxypropyl methylcellulose ni polymer izwi cyane mu gushonga amazi ikora igisubizo gisobanutse kandi gihamye mumazi kandi ikoreshwa cyane mubikorwa bya farumasi, ibiribwa nubwubatsi. Nibintu bitari ionic selulose bishingiye kubintu fatizo bitezimbere guhuza no guhuza ibicuruzwa byanyuma. Kugirango hamenyekane imikorere myiza ya hydroxypropyl methylcellulose, ibicuruzwa bigomba gupimwa kandi byujuje ibisabwa mbere yo kubikoresha. Muri iki kiganiro, tuzaganira ku buryo butatu bwizewe bwo kuvuga ubwiza bwa hydroxypropyl methylcellulose.
1. Ikizamini cya Viscosity
Ubukonje bwa hydroxypropyl methylcellulose nikintu cyingenzi kugirango umenye ubwiza bwacyo. Viscosity ni ukurwanya amazi gutemba kandi bipimwa muri centipoise (cps) cyangwa mPa.s. Ubukonje bwa hydroxypropyl methylcellulose buratandukana ukurikije uburemere bwa molekile hamwe nintera yo gusimburwa. Urwego rwo hejuru rwo gusimbuza, niko igabanuka ryibicuruzwa.
Kugirango ugerageze ubwiza bwa hydroxypropyl methylcellulose, ushonga ibicuruzwa bike mumazi hanyuma ukoreshe viscometer kugirango upime ubwiza bwumuti. Ubwiza bwigisubizo bugomba kuba mubisabwa byatanzwe nuwatanze ibicuruzwa. Igicuruzwa cyiza cya hydroxypropyl methylcellulose kigomba kugira ubwiza buhoraho, ibyo bikaba byerekana ubuziranenge nubunini buke.
2. Ikizamini cyo gusimbuza
Urwego rwo gusimbuza bivuga ikigereranyo cyumubare wamatsinda ya hydroxyl kuri selilose yasimbuwe na hydroxypropyl cyangwa methyl. Urwego rwo gusimbuza ni ikimenyetso cyerekana ubuziranenge bwibicuruzwa, urwego rwo hejuru rusimburwa, ibicuruzwa bisukuye. Ibicuruzwa byiza bya hydroxypropyl methylcellulose bigomba kugira urwego rwo hejuru rwo gusimburwa.
Kugirango ugerageze urwego rwo gusimburwa, titre ikorwa hamwe na hydroxide ya sodium na aside hydrochloric. Menya ingano ya hydroxide ya sodium ikenewe kugirango ubuze hydroxypropyl methylcellulose no kubara urugero rwo gusimbuza ukoresheje formula ikurikira:
Impamyabumenyi yo gusimbuza = ([Umubumbe wa NaOH] x [Molarity ya NaOH] x 162) / ([Uburemere bwa Hydroxypropyl Methyl Cellulose] x 3)
Urwego rwo gusimbuza rugomba kuba murwego rusabwa rutangwa nuwatanze ibicuruzwa. Urwego rwo gusimbuza ibicuruzwa byiza bya hydroxypropyl methylcellulose bigomba kuba mubisabwa.
3. Ikizamini cyo gukemura
Ubushobozi bwa hydroxypropyl methylcellulose nikindi kintu cyingenzi kigena ubuziranenge bwacyo. Ibicuruzwa bigomba gushonga byoroshye mumazi kandi ntibigire ibibyimba cyangwa geles. Ibicuruzwa byiza bya hydroxypropyl methylcellulose bigomba gushonga vuba kandi neza.
Kugirango ukore ikizamini cyo gukemura, ushonga ibicuruzwa bike mumazi hanyuma ukangure igisubizo kugeza ushonga burundu. Igisubizo kigomba kuba gisobanutse kandi kitarimo ibibyimba cyangwa geles. Niba ibicuruzwa bidashonga byoroshye cyangwa bigakora ibibyimba cyangwa geles, birashobora kuba ikimenyetso cyubuziranenge.
Mu gusoza, hydroxypropyl methylcellulose ni ibikoresho fatizo bikoreshwa mu nganda zitandukanye. Kugirango hamenyekane ubuziranenge bwibicuruzwa, ibizamini byo kwisiga, gusimbuza no gukemura ibibazo birakorwa. Ibi bizamini bizafasha kumva neza ibiranga ibicuruzwa no gufasha gutandukanya ubuziranenge bwabyo. Hydroxypropyl methylcellulose yo mu rwego rwo hejuru ifite ubwiza buhoraho, urwego rwo hejuru rwo gusimburwa, kandi igashonga vuba kandi kimwe mumazi.
