Hydroxypropyl methylcellulose (HPMC) ninyongeramusaruro inyuranye ikoreshwa cyane mubikorwa byubwubatsi, cyane cyane mumashanyarazi yumye. Uru ruganda ni umuryango wa selile ether kandi ukomoka kuri selile naturel. HPMC ikomatanyirizwa hamwe no kuvura selile hamwe na oxyde ya propylene na methyl chloride, bikavamo selile yahinduwe hamwe nibintu byongerewe imbaraga. Kwiyongera kwa HPMC kumyuma ivanze ya minisiteri itanga ibintu bitandukanye byifuzwa, bikagira uruhare runini mukubaka inyubako nububiko bugezweho.
A.HPMC imiterere n'imikorere:
1.Imiterere yimiti:
Hydroxypropylmethylcellulose ifite imiterere igoye irimo hydrophilique na hydrophobique. Amatsinda ya hydroxypropyl na methyl yatangijwe mugihe cya synthesis atanga molekile ibintu byihariye.
2. Amazi meza:
HPMC irashobora gushonga amazi, ikayemerera gushonga mumazi akonje kugirango ibe igisubizo kiboneye kandi cyiza. Iyi mitungo irakomeye mugukama kuvanga minisiteri kuko itanga ikwirakwizwa ryiza hamwe nuburinganire bwanyuma.
3. Gutanga ubushyuhe:
HPMC ihura nuburyo bwo guhinduranya ibintu, bivuze ko ishobora gukora gel iyo ishyushye ikagaruka kubisubizo iyo bikonje. Iyi myitwarire ifasha kunoza gufata neza amazi no gukora byavanze na minisiteri.
4. Ubushobozi bwo gukora firime:
HPMC ifite imiterere-ya firime kandi ikora firime ikingira hejuru ya minisiteri. Filime yongerera imbaraga, igabanya umukungugu, kandi igateza imbere uburebure bwa minisiteri.
B. Uruhare rwa HPMC muri minisiteri ivanze yumye:
1. Kubika amazi:
Imwe mumikorere yingenzi ya HPMC muri minisiteri yumye-ivanze ni ukongera amazi. Imiterere ya hydrophilique ya molekile ya HPMC ituma yakira kandi ikagumana ubushuhe, ikabuza minisiteri gukama imburagihe. Ibi nibyingenzi kubikorwa byigihe kirekire no gukira neza ya minisiteri.
2. Kunoza imikorere:
Ongeramo HPMC kumisha ivanze ya minisiteri itezimbere imikorere kandi ihamye. Ifasha kugera kubintu byoroshye ndetse no gushyira mubikorwa bya minisiteri, byoroshye kubyitwaramo no kubishyira.
3. Kugabanya kugabanuka:
HPMC igira uruhare mukurwanya sag ya minisiteri, ikayirinda gusenyuka cyangwa kugabanuka hejuru yubutumburuke. Ibi nibyingenzi cyane mugihe ukorera ahirengeye cyangwa kurukuta.
4. Kongera imbaraga:
Ubushobozi bwo gukora firime ya HPMC bufasha kunoza imikoranire hagati ya minisiteri na substrate zitandukanye. Ibi nibyingenzi kugirango ugere kumurongo ukomeye kandi muremure mubikorwa byubaka.
5. Ingaruka mugushiraho igihe:
Mugihe HPMC idahindura cyane mugihe cyambere cyo gushiraho minisiteri, irashobora kugira ingaruka kumikorere rusange kandi ikagira uruhare mugutezimbere kwigihe kirekire.
6. Guhinduka no guhangana:
Filime yakozwe na HPMC itanga imiterere ya minisiteri, bigatuma irwanya gucika. Ibi nibyiza cyane cyane aho imiterere yimiterere ishobora kugaragara.
7. Guhagarara mubihe bibi:
HPMC itanga ibyuma byumye bivanze hamwe nibidukikije mugihe cyibidukikije bitandukanye, harimo no guhura nikirere gikabije. Itezimbere muri rusange kuramba no gukora bya minisiteri.
C. Inyandiko zisaba:
1. Igipimo:
Umubare ukwiye wa HPMC biterwa nibisabwa byihariye bivangwa na minisiteri, harimo imitungo yifuzwa hamwe nibisabwa. Gutekereza neza no kwipimisha nibyingenzi muguhitamo igipimo cyiza.
2. Guhuza:
HPMC irahujwe nibindi bintu bitandukanye byongeweho nibindi bikoresho bikoreshwa mugukoresha imvange yumye. Ariko, ibizamini byo guhuza bigomba gukorwa kugirango harebwe imikorere isabwa kandi wirinde imikoranire mibi.
3. Ibipimo ngenderwaho:
Ubwiza bwa HPMC bukoreshwa mumashanyarazi yumye bugomba kubahiriza ibipimo byinganda nibisobanuro. Gukurikiza ibipimo ngenderwaho byerekana imikorere ya minisiteri ihamye kandi yizewe.
mu gusoza:
Hydroxypropyl methylcellulose (HPMC) ninyongeramusaruro myinshi igira uruhare runini mugutezimbere imikorere yimvange yumye. Ihuza ryihariye ryimitungo, harimo kubika amazi, kunoza imikorere nubushobozi bwo gukora firime, bituma iba igice cyibikorwa byubwubatsi bugezweho. Mugihe ibikoresho byubwubatsi bikomeje kugenda bitera imbere, ikoreshwa rya HPMC mumashanyarazi yumye-ivanze irashobora gufasha guteza imbere imiterere irambye, ihindagurika kandi irambye.
