Kuvuga kuri Hydroxypropyl Methyl Cellulose (HPMC)

1. Ni irihe zina rya hydroxypropyl methylcellulose?

—— Igisubizo: Hydroxypropyl Methyl Cellulose, Icyongereza: Hydroxypropyl Methyl Cellulose Amagambo ahinnye: HPMC cyangwa MHPC Alias: Hypromellose; Cellulose Hydroxypropyl Methyl Ether; Hypromellose, Cellulose, 2-hydroxypropylmethyl Cellulose ether. Cellulose hydroxypropyl methyl ether Hyprolose.

2. Ni ubuhe buryo bukoreshwa bwa hydroxypropyl methylcellulose (HPMC)?

—— Igisubizo: HPMC ikoreshwa cyane mubikoresho byubwubatsi, gutwikira, ibisigazwa byubukorikori, ububumbyi, ubuvuzi, ibiryo, imyenda, ubuhinzi, kwisiga, itabi nizindi nganda. HPMC irashobora kugabanywa mubyiciro byubwubatsi, icyiciro cyibiribwa nicyiciro cya farumasi ukurikije intego. Kugeza ubu, ibyinshi mubicuruzwa byo murugo ni urwego rwubwubatsi. Mu cyiciro cyubwubatsi, ifu ya putty ikoreshwa mubwinshi, hafi 90% ikoreshwa kubifu ya putty, naho ibindi bikoreshwa mumasima ya sima na kole.

3. Hariho ubwoko bwinshi bwa hydroxypropyl methylcellulose (HPMC), kandi ni irihe tandukaniro mugukoresha?

—— Igisubizo: HPMC irashobora kugabanywa muburyo bwubwoko nubwoko bushyushye. Ibicuruzwa byubwoko bukwirakwira vuba mumazi akonje bikabura mumazi. Muri iki gihe, amazi ntagira ubwiza kuko HPMC ikwirakwizwa mumazi gusa nta gushonga nyabyo. Hafi yiminota 2, ubwiza bwamazi bugenda bwiyongera buhoro buhoro, bukora colloid ibonerana. Ibicuruzwa bishyushye, iyo bihuye namazi akonje, birashobora gukwirakwira vuba mumazi ashyushye bikabura mumazi ashyushye. Iyo ubushyuhe bugabanutse ku bushyuhe runaka, ibishishwa bizagaragara buhoro buhoro kugeza igihe bibumbiye mu mucyo. Ubwoko bushyushye burashobora gukoreshwa gusa mubifu ya pome na minisiteri. Muri kole yamazi no gusiga irangi, hazabaho guterana ibintu kandi ntibishobora gukoreshwa. Ubwoko bwakanya bufite intera yagutse ya porogaramu. Irashobora gukoreshwa mu ifu yuzuye ifu na minisiteri, hamwe na kole yamazi hamwe n irangi, nta kubuza.

4. Nigute ushobora guhitamo hydroxypropyl methylcellulose (HPMC) kubwimpamvu zitandukanye?

—— Igisubizo :: Gukoresha ifu ya putty: Ibisabwa ni bike, kandi ibishishwa ni 100.000, birahagije. Icyangombwa nukubungabunga amazi neza. Gukoresha minisiteri: ibisabwa hejuru, viscosity nyinshi, 150.000 nibyiza. Gukoresha kole: ibicuruzwa byihuse hamwe nubwiza bwinshi birasabwa.

5. Ni iki gikwiye kwitabwaho mugushira mubikorwa isano iri hagati yubukonje nubushyuhe bwa HPMC?

—— Igisubizo: Ubukonje bwa HPMC buringaniye butandukanye nubushyuhe, ni ukuvuga ko ubukonje bwiyongera uko ubushyuhe bugabanuka. Ubukonje bwibicuruzwa dukunze kuvuga bivuga ibisubizo byikizamini cyumuti wacyo wa 2% mubushyuhe bwa dogere selisiyusi 20.

Mubikorwa bifatika, twakagombye kumenya ko mubice bifite itandukaniro rinini ryubushyuhe hagati yizuba nimbeho, birasabwa gukoresha ubukonje buke ugereranije nimbeho, bifasha cyane kubaka. Bitabaye ibyo, iyo ubushyuhe buri hasi, ubukonje bwa selile buziyongera, kandi ukuboko kumva kuremereye mugihe cyo gukuraho.

Ubucucike buciriritse: 75000-100000 bukoreshwa cyane muri putty

Impamvu: gufata neza amazi

Ubukonje bwinshi: 150000-200000 Byakoreshejwe cyane cyane mubice bya polystirene yubushyuhe bwumuriro wa minisiteri ya rubber na vitamine ya mikorobe ya vitamine.

Impamvu: Ubukonje buri hejuru, minisiteri ntabwo yoroshye kugwa, sag, kandi kubaka biratera imbere.

6. HPMC ni ether ya selile idafite ionic, none non-ionic niki?

—— Igisubizo: Mu magambo y’abalayiki, ibitari ion ni ibintu bidatera ioni mu mazi. Ionisation bivuga inzira electrolyte igabanyijemo ion zishishwa zishobora kugenda mubwisanzure mumashanyarazi yihariye (nk'amazi, inzoga). Kurugero, sodium chloride (NaCl), umunyu turya burimunsi, ushonga mumazi na ionize kugirango ubyare sodium yimuka yimuka kubuntu (Na +) byuzuye neza na ioni ya chloride (Cl) byashizwemo nabi. Nukuvuga ko, iyo HPMC ishyizwe mumazi, ntabwo izitandukanya na ion zashizwemo, ahubwo ibaho muburyo bwa molekile.
