Nigute ushobora kugenzura ivu rya Hydroxypropyl Methylcellulose (HPMC)?

Kugenzura ivu rya Hydroxypropyl Methylcellulose (HPMC) bikubiyemo kumenya ijanisha ryibisigazwa by’ibinyabuzima bidasigara nyuma y’ibinyabuzima kimaze gutwikwa. Dore uburyo rusange bwo gukora ibizamini bya ivu kuri HPMC:

Ibikoresho bikenewe:

1. Hydroxypropyl Methylcellulose (HPMC) icyitegererezo
2. Itanura rya muffle cyangwa itanura
3. Kubamba no gupfundikanya (bikozwe mubikoresho bya inert nka farisari cyangwa quartz)
4. Desiccator
5. Impirimbanyi zisesenguye
6. Ubwato bwo gutwika (ntibigomba)
7. Indimi cyangwa abafite ingenzi

Inzira:

1. Gupima icyitegererezo:
   • Gupima ubusa (m1) kuri 0.1 mg hafi ukoresheje impirimbanyi zisesenguye.
   • Shira urugero ruzwi rw'icyitegererezo cya HPMC (mubisanzwe garama 1-5) mubikomeye hanyuma wandike uburemere hamwe bw'icyitegererezo kandi gikomeye (m2).
2. Uburyo bwo gushisha:
   • Shira ikintu gikomeye kirimo icyitegererezo cya HPMC mu itanura rya muffle cyangwa itanura ryoza.
   • Shyushya itanura gahoro gahoro kugeza ku bushyuhe bwagenwe (mubisanzwe 500-600 ° C) kandi ugumane ubu bushyuhe mugihe cyagenwe (mubisanzwe amasaha 2-4).
   • Menya neza ko gutwikwa kwuzuye kama, usize ivu gusa.
3. Gukonja no gupima:
   • Nyuma yo gukaraba birangiye, kura ikibumbano mu itanura ukoresheje ingofero cyangwa abafite ingenzi.
   • Shira ingirakamaro n'ibiyirimo muri desiccator kugirango ukonje ubushyuhe bwicyumba.
   • Bimaze gukonjeshwa, ongera usige ibisigazwa by'ingenzi n'ivu (m3).
4. Kubara:
   • Kubara ivu ryikitegererezo cya HPMC ukoresheje formula ikurikira: Ibirimo ivu (%) = [(m3 - m1) / (m2 - m1)] * 100
5. Ibisobanuro:
   • Ibisubizo byabonetse byerekana ijanisha ryibintu bitavanze ivu biboneka murugero rwa HPMC nyuma yo gutwikwa. Agaciro kerekana ubuziranenge bwa HPMC nubunini bwibintu bidasigara bihari bihari.
6. Raporo:
   • Menyesha ivu agaciro k ivu hamwe nibisobanuro byose nkibisabwa, ibizamini byerekana, nuburyo bwakoreshejwe.

Inyandiko:

• Menya neza ko umupfundikizo n'umupfundikizo bifite isuku kandi bitarimo umwanda uwo ariwo wose mbere yo gukoreshwa.
• Koresha itanura rya muffle cyangwa ivu ryogeje rifite ubushobozi bwo kugenzura ubushyuhe kugirango ushushe hamwe nibisubizo nyabyo.
• Koresha ibikomeye n'ibiyirimo witonze kugirango wirinde gutakaza ibintu cyangwa kwanduza.
• Kora uburyo bwo kumesa ahantu hafite umwuka uhagije kugirango wirinde gutwikwa nibicuruzwa.

Ukurikije ubu buryo, urashobora kumenya neza ibiri mu ivu rya Hydroxypropyl Methylcellulose (HPMC) hanyuma ugasuzuma ubuziranenge bwabyo.
