Njira yothetsera (Hydroxypropyl Methyl Cellulose)HPMC
Kusungunuka kwa Hydroxypropyl Methylcellulose (HPMC) kumaphatikizapo kumwaza ufa wa polima m'madzi pansi pazikhalidwe zoyendetsedwa bwino kuti zitsimikizire kuti hydration yoyenera ndi kusungunuka. Nayi njira wamba yosungunula HPMC:
Zofunika:
- HPMC ufa
- Madzi osungunuka kapena opangidwa ndi deionized (zotsatira zabwino)
- Kusakaniza chotengera kapena chotengera
- Stirrer kapena kusakaniza zida
- Zida zoyezera (ngati dosing yolondola ikufunika)
Njira Yoyimitsa:
- Konzani Madzi: Yesani kuchuluka kofunikira kwamadzi osungunuka kapena opangidwa molingana ndi kuchuluka komwe mukufuna yankho la HPMC. Ndikofunikira kugwiritsa ntchito madzi apamwamba kwambiri kuti zonyansa kapena zowononga zisasokoneze njira yosungunuka.
- Kutenthetsa Madzi (Ngati mukufuna): Ngati n'koyenera, tenthetsani madzi kutentha kwapakati pa 20 ° C mpaka 40 ° C (68 ° F mpaka 104 ° F) kuti athetse kusungunuka. Kutentha akhoza imathandizira ndi hydration wa HPMC ndi kusintha kubalalitsidwa kwa polima particles.
- Pang'onopang'ono Onjezani HPMC Powder: Pang'onopang'ono yonjezerani ufa wa HPMC m'madzi pamene mukugwedeza mosalekeza kuti muteteze clumping kapena agglomeration. Ndikofunikira kuwonjezera ufa pang'onopang'ono kuti muwonetsetse kubalalitsidwa kofanana ndikupewa kupanga zotupa.
- Pitirizani Kugwedeza: Pitirizani kugwedeza kapena kugwedezeka kwa chisakanizo mpaka ufa wa HPMC utamwazidwa kwathunthu ndi kuthiridwa madzi. Izi nthawi zambiri zimatenga mphindi zingapo, kutengera kukula kwa tinthu ta HPMC ufa ndi liwiro loyambitsa.
- Lolani Hydration: Mukawonjezera ufa wa HPMC, lolani kuti chisakanizocho chiyime kwa nthawi yokwanira kuti mutsimikize kuti hydration yonse ya polima. Izi zitha kukhala kuyambira mphindi 30 mpaka maola angapo, kutengera kalasi yeniyeni ndi kukula kwa tinthu ta HPMC.
- Sinthani pH (ngati kuli kofunikira): Kutengera kugwiritsa ntchito, mungafunike kusintha pH ya yankho la HPMC pogwiritsa ntchito njira za asidi kapena alkali. Izi ndizofunikira makamaka pamagwiritsidwe omwe kukhudzidwa kwa pH kuli kofunikira, monga pazamankhwala kapena zamunthu payekha.
- Zosefera (ngati kuli kofunikira): Ngati yankho la HPMC lili ndi tinthu tating'onoting'ono tosasungunuka kapena zophatikizika zosasungunuka, pangakhale kofunikira kusefa yankholo pogwiritsa ntchito sieve yabwino ya mauna kapena pepala losefera kuti muchotse zolimba zotsalira.
- Sungani kapena Gwiritsani Ntchito: HPMC ikasungunuka ndi kuthiridwa madzi, yankho liri lokonzeka kugwiritsidwa ntchito. Itha kusungidwa mu chidebe chosindikizidwa kapena kugwiritsidwa ntchito nthawi yomweyo pazinthu zosiyanasiyana monga mankhwala, zodzoladzola, zomanga, kapena zakudya.
Ndemanga:
- Pewani kugwiritsa ntchito madzi olimba kapena madzi okhala ndi mchere wambiri, chifukwa zingakhudze njira yowonongeka ndi ntchito ya yankho la HPMC.
- Nthawi yowonongeka ndi kutentha kungasinthe malinga ndi kalasi yeniyeni, kukula kwa tinthu, ndi kalasi ya viscosity ya ufa wa HPMC wogwiritsidwa ntchito.
- Nthawi zonse tsatirani malingaliro ndi malangizo a wopanga pokonzekera mayankho a HPMC, chifukwa magiredi osiyanasiyana amatha kukhala ndi zofunikira pakuyimitsa.
