Ubumenyi burwanya hydroxypropyl methylcellse hpmc

HydroxyPropyl Methylcellsellse (HPMC) ni selile itari ionic yakozwe muri selile ya selile ya selile ya selile ya selile yatunganijwe neza. Nibipfumu bidafite impumuro nziza kandi bitaryoshye kandi bitoroshye bibyimba mu gicu gisobanutse cyangwa gito gitangaje mumazi akonje. Ifite kubyimba, guhuza, gutatana, guteranya, gushinga film, guhagarikwa, kwishyuza, gutemba, gukomera, kugumana imitungo ya colloid. HydroxyPropyl Methyl Cellulose na Methyl selile irashobora gukoreshwa mu bikoresho byo kubaka, inganda za Synthotique, inganda za Simber, imiti, imiti, ibiryo, imiti, imiti ya buri munsi n'izindi ngambo n'izindi nganda.

Ingaruka zo kugumana amazi nihame rya hydroxyPropyl methylcellse hpmc

Cellulose Ether Hpmc cyane cyane akina uruhare rwo kugumana amazi no kubyimba muri sima na parsum, kandi birashobora kunoza neza imbaraga zo guhuriza hamwe na sag irwanya indwara.

Ibintu nkubushyuhe bwikirere, ubushyuhe hamwe numuvuduko wumuvuduko wumuyaga bizagira ingaruka kumibare y'amaraso muri sima na parpsum. Kubwibyo, mubihe bitandukanye, hariho itandukaniro muburyo bwo kugumana amazi hamwe na HPMC imwe yongeyeho. Mubwubatsi bwihariye, ingaruka zo kugumana amazi zirashobora guhindurwa no kwiyongera cyangwa kugabanya umubare wa HPMC yongeyeho. Kugumana amazi ya methyl selile ether imiterere yubushyuhe nicyo kimenyetso cyingenzi kugirango utandukane ubwiza bwa methyl. Ibicuruzwa byiza bya HPMC birashobora gukemura neza ikibazo cyo kugumana amazi munsi yubushyuhe bwinshi. Mubihe byubushyuhe bwinshi, cyane cyane mubice bishyushye kandi byumye kandi byubatse byubwubatsi bwizuba, HPMC yo hejuru ya HPMC isabwa kunoza ubushake bwo kugumana amazi. Ubuziranenge bwa HPMC ifite uburinganire bwiza cyane. Uburyo bwamatsinda ya HydroxyPropy na HydroxyPropoplex yagabanijwe neza kuruhande rwa molekile, bishobora kunoza ubushobozi bwa atome ya ogisijeni kuri hydroxyl na ethers ingoma yo kwiteranya namazi kugirango ikore hydrogen. , kugirango amazi yubuntu ahinduke amazi meza, kugirango agenzure neza imyanya y'amazi iterwa n'ubushyuhe bwo hejuru, kandi igahagarikwa amazi menshi.

Ubudodo bukomeye HPMC irashobora gutatana neza kandi neza muri sima ishingiye kuri sirtar na gysum, kandi igahinge filime ihamye iragenda, kandi ingufu mu bikoresho Hydtion reaction yibikoresho byatewe bizameza imbaraga zinguzanyo nimbaraga zituje zibikoresho. Kubwibyo, mubushyuhe bwizuba, kugirango tugere ku ngaruka zo kugumana amazi, birakenewe kongeramo ibicuruzwa byiza bya HPMC muburyo buhagije ukurikije formulaire ihagije ukurikije formulaire ihagije ukurikije formulaire ihagije ukurikije formulaire ihagije ukurikije formulaire ihagije ukurikije formulaire ihagije ukurikije formulaire, bitabaye ibyo, kugabanya imbaraga, guca imbaraga, kunyeganyega no kumena guterwa cyane. ibibazo, ariko kandi byongera ingorane zububiko. Mugihe ubushyuhe butonyanga, umubare wamazi HPMC yongeyeho irashobora kugabanuka buhoro buhoro, kandi ingaruka zimwe zo kugumana amazi zirashobora kugerwaho.

Kugumana amazi ya hydroxyPropyl methylcellsellse ibicuruzwa ubwabyo bikunze kwibasirwa nibintu bikurikira:

1. Kundambiranya selile ether hpmc

Kumenyera HPMC, uburyo na hydroxyPropoxyl buratangwa, kandi igipimo cyo kugumana amazi ni kinini.

2. Cekwil Ether Hpmc Ubushyuhe bwa Gel

Hejuru yubushyuhe bwa gel, igipimo cyo kugumana amazi; Bitabaye ibyo, hagamijwe kugabana amazi.

3. Ubugari bwa ether mpmc viscosity

Iyo virusi ya HPMC yiyongera, umubare wogumana amazi nawo uriyongera; Iyo ubushyuhe bugera ku rwego runaka, kwiyongera kw'ibipimo by'amazi bikunda kwitonda.

4. Umubare wongeyeho wa selile ether hpmc

Ingano nini ya selile Ether HPMC yongeyeho, igipimo cyo guhohotera amazi ningaruka nziza yo kugumana amazi. Mu rwego rwo kuwa 0.25-0.6 Iyo amafaranga yo kwigomeka yiyongera, kwiyongera kw'ifitu ya kanseri y'amazi bitinda.
