Hydroxypropyl Methyl Cellulose HPMC
Hydroxypropyl methylcellulose (HPMC), ether ya selile idafite ionic, ikomoka kuri selile karemano ikoresheje urukurikirane rukomeye rwimiti. Iyi poro yera irangwa na kamere yayo idafite impumuro nziza kandi itaryoshye, bigatuma idafite uburozi kandi ifite umutekano kubikorwa bitandukanye. Kimwe mu bintu byingenzi bigaragara ni ubushobozi bwayo bwo gushonga mu mazi akonje, bikavamo igisubizo kibonerana. HPMC ifite ibintu byinshi byimikorere, harimo kubyimba, gufatira hamwe, gutatanya, emulisation, hamwe nubushobozi bwo gukora film. Byongeye kandi, irusha cyane kubika amazi, gelation, hamwe nibikorwa byubutaka, bigatuma iba uruganda rwinshi mu nganda nyinshi, nka farumasi, umusaruro wibiribwa, ubwubatsi, no kwisiga.
Mu rwego rwubwubatsi, HPMC isanga porogaramu zitari nke zikenewe mu kuzamura ireme n’ubushobozi bwibikoresho byubaka. Kurugero, iyo byinjijwe muri sima-umucanga, HPMC itezimbere cyane itandukanyirizo ryibikoresho, bigatuma plastike yiyongera kandi igakomeza gufata neza amazi mugukoresha minisiteri. Iyi ngingo ni ingenzi, kuko ifasha gukumira ibice byubatswe, bityo bikongerera ubuzima nubuzima bwubwubatsi. Mu buryo nk'ubwo, mu rwego rwa ceramic tile mortar, HPMC ntabwo iteza imbere gufata amazi gusa ahubwo inatezimbere hamwe na plastike, ningirakamaro mugukoresha neza no kuramba nta kibazo cya poro.
Byongeye kandi, HPMC yubahiriza amabwiriza akomeye y’umutekano, kumenyekana nk’inyongeramusaruro y’ibiribwa idafite uburozi kugira ngo uyikoreshe, udafite agaciro ka karori kandi ntukarakaze ku ruhu no mu mucyo. Ukurikije amabwiriza ya FDA na FAO / OMS, gufata buri munsi kwemerwa kwa HPMC bishyirwa kuri 25mg / kg, bitanga ibyiringiro byo kuyikoresha mubisabwa bitandukanye. Ariko, kwirinda birakenewe mugihe ukoresha HPMC kugirango umutekano ube mugihe cyo kuyikoresha. Birasabwa kwambara ibikoresho birinda, kwirinda guhura n’amasoko y’umuriro, no kugabanya kubyara umukungugu ahantu hafunzwe kugirango bigabanye ingaruka ziturika. Byongeye kandi, HPMC igomba kubikwa ahantu humye, ihumeka neza, ikingiwe nizuba ryinshi nubushuhe, hitawe kubitekerezo bisabwa mugihe cyo gutwara kugirango birinde imvura nibindi bintu byikirere. HPMC ipakirwa neza mumifuka 25 kg ikozwe muri polypropilene, ikomatanyirijwe hamwe na polyethylene kugirango hongerweho uburinzi, byemeza ko ibicuruzwa bikomeza gufungwa kandi bidahwitse kugeza bikoreshejwe.
