Momwe mungayang'anire phulusa la Hydroxypropyl Methylcellulose (HPMC)?

Kuyang'ana phulusa la Hydroxypropyl Methylcellulose (HPMC) kumaphatikizapo kudziwa kuchuluka kwa zotsalira za inorganic zomwe zatsala pambuyo poti zidawotchedwa.Nayi njira yanthawi zonse yoyesa zinthu za phulusa za HPMC:

Zofunika:

1. Hydroxypropyl Methylcellulose (HPMC) chitsanzo
2. Ng'anjo yamoto kapena ng'anjo yamoto
3. Crucible ndi chivindikiro (chopangidwa ndi zinthu zopanda pake monga porcelain kapena quartz)
4. Desiccator
5. Kuwerengera bwino
6. Boti loyaka moto (ngati mukufuna)
7. Zibano kapena zonyamula crucible

Kachitidwe:

1. Kuyeza kwachitsanzo:
   • Yezerani crucible yopanda kanthu (m1) mpaka 0.1 mg wapafupi pogwiritsa ntchito sikelo yowunikira.
   • Ikani chiwerengero chodziwika cha HPMC chitsanzo (nthawi zambiri 1-5 magalamu) mu crucible ndi kulemba ophatikizana kulemera kwa chitsanzo ndi crucible (m2).
2. Njira ya ashing:
   • Ikani crucible yomwe ili ndi chitsanzo cha HPMC mu ng'anjo ya muffle kapena ng'anjo ya phulusa.
   • Kutenthetsa ng'anjo pang'onopang'ono mpaka kutentha kwapadera (nthawi zambiri 500-600 ° C) ndikusunga kutentha kumeneku kwa nthawi yokonzedweratu (nthawi zambiri maola 2-4).
   • Onetsetsani kuyaka kwathunthu kwa organic, kusiya phulusa lokhalokha.
3. Kuziziritsa ndi kulemera kwake:
   • Pambuyo pa phulusa latha, chotsani crucible mu ng'anjo pogwiritsa ntchito mbano kapena crucible holder.
   • Ikani crucible ndi zomwe zili mkati mwake mu desiccator kuti muzizizira kutentha kwa chipinda.
   • Mukaziziritsa, yesaninso zotsalira za crucible ndi phulusa (m3).
4. Kuwerengera:
   • Kuwerengera phulusa lachitsanzo cha HPMC pogwiritsa ntchito njira iyi: Phulusa (%) = [(m3 - m1) / (m2 - m1)] * 100
5. Kutanthauzira:
   • Zotsatira zomwe zapezedwa zikuyimira kuchuluka kwa phulusa la inorganic lomwe lili mu zitsanzo za HPMC pambuyo poyaka.Mtengowu ukuwonetsa chiyero cha HPMC komanso kuchuluka kwa zinthu zotsalira zomwe zilipo.
6. Lipoti:
   • Nenani za mtengo wa phulusa limodzi ndi zina zilizonse zokhudzana ndi kuyezetsa, chizindikiritso cha zitsanzo, ndi njira zomwe zagwiritsidwa ntchito.

Ndemanga:

• Onetsetsani kuti crucible ndi chivindikiro ndi zoyera komanso zopanda kuipitsidwa kulikonse musanagwiritse ntchito.
• Gwiritsani ntchito ng'anjo ya muffle kapena ng'anjo yamoto yokhala ndi mphamvu zowongolera kutentha kuti muwonetsetse kutentha kofanana ndi zotsatira zolondola.
• Gwirani mosamala crucible ndi zomwe zili m'kati mwake kuti musatayike kapena kuipitsidwa.
• Chitani phulusa pamalo olowera mpweya wabwino kuti mupewe kuyaka ndi zinthu.

Potsatira njirayi, mukhoza kudziwa molondola phulusa zili Hydroxypropyl Methylcellulose (HPMC) zitsanzo ndi kuwunika chiyero ndi khalidwe lawo.
