Nzira yekutarisa sei madota eHydroxypropyl Methylcellulose (HPMC)?

Kuongorora madota eHydroxypropyl Methylcellulose (HPMC) kunosanganisira kuona chikamu chezvisaririra zvasara mushure mekunge zvinhu zveorganic zvapiswa. Heino maitiro akajairwa ekuita madota emukati meyedzo yeHPMC:

Zvishandiso Zvinodiwa:

1. Hydroxypropyl Methylcellulose (HPMC) muenzaniso
2. Muffle furnace kana ashing furnace
3. Crucible uye chivharo (chakagadzirwa neinert zvinhu senge porcelain kana quartz)
4. Desiccator
5. Analytical balance
6. Igwa rinopisa (optional)
7. Tongs kana crucible holders

Maitiro:

1. Kuyera kwemuenzaniso:
   • Weresa crucible isina chinhu (m1) kune iri pedyo 0.1 mg uchishandisa analytical balance.
   • Isa huwandu hunozivikanwa hweHPMC sampuli (kazhinji 1-5 magiramu) mucrucible uye rekodha huremu hwakasanganiswa hwesample uye crucible (m2).
2. Ashing process:
   • Isa crucible ine HPMC sampuro muchoto chemuffle kana muchoto wedota.
   • Pisa choto zvishoma nezvishoma kune tembiricha yakatarwa (kazhinji 500-600 ° C) uye chengetedza tembiricha iyi kwenguva yakatarwa (kazhinji maawa 2-4).
   • Ita shuwa kupisa kwakazara kweiyo organic material, ichisiya chete inorganic dota.
3. Kutonhodza nekuyera:
   • Mushure mekunge madota apera, bvisa crucible kubva muchoto uchishandisa mbambo kana crucible holders.
   • Isa crucible uye zvirimo mu desiccator kuti itonhorere kusvika kune tembiricha yekamuri.
   • Kana yatonhodzwa, yera zvakare crucible uye madota asara (m3).
4. Kuverenga
   • Verenga madota emumuenzaniso weHPMC uchishandisa fomula inotevera: Madota emukati (%) = [(m3 - m1) / (m2 - m1)] * 100
5. Dudziro
   • Mhedzisiro yakawanikwa inomiririra chikamu cheiyo inorganic ash yemukati iripo muHPMC sampuli mushure mekupiswa. Kukosha uku kunoratidza kuchena kweHPMC uye huwandu hwezvasara inorganic zvinhu zviripo.
6. Reporting:
   • Taura kukosha kwemukati wedota pamwe chete nechero ruzivo rwakadai semamiriro ekuyedzwa, sampuli yekuzivikanwa, uye nzira inoshandiswa.

Notes:

• Ita shuwa kuti crucible uye chivharo zvakachena uye hazvina kusvibiswa usati washandisa.
• Shandisa muffle choto kana ashing vira ine tembiricha yekudzora masimba kuti uve nechokwadi chekudziya yunifomu uye mhedzisiro chaiyo.
• Bata crucible uye zvirimo nekungwarira kudzivirira kurasikirwa kwezvinhu kana kusvibiswa.
• Ita ashing process munzvimbo ine mhepo inofefetera kuti udzivise kusangana nekupisa ne-zvigadzirwa.

Nekutevera maitiro aya, unogona kunyatsoona madota eHydroxypropyl Methylcellulose (HPMC) samples uye kuongorora kuchena kwavo uye mhando.
