Joang ho hlahloba litaba tsa molora oa Hydroxypropyl Methylcellulose (HPMC)?

Ho hlahloba dikahare tsa molora wa Hydroxypropyl Methylcellulose (HPMC) ho kenyelletsa ho fumana peresente ya masalla a inorganic a setseng ka mora hore dikarolo tsa organic di tjheswe. Mona ke mokhoa o akaretsang oa ho etsa tlhahlobo ea litaba tsa molora bakeng sa HPMC:

Lintho Tse Hlokehang:

1. Mohlala oa Hydroxypropyl Methylcellulose (HPMC).
2. Sebopi sa muffle kapa sebopi sa molora
3. Crucible le sekwahelo (se entsoeng ka thepa e sa sebetseng joalo ka porcelain kapa quartz)
4. Desiccator
5. Ho leka-lekanya ho leka-lekanya
6. Sekepe se tukang mollo (ho ikhethela)
7. Lipatso kapa litšepe tsa crucible

Mokhoa:

1. Boima ba mohlala:
   • Beha crucible e se nang letho (m1) ho isa ho 0.1 mg e haufi u sebelisa tekanyo ea tlhahlobo.
   • Beha palo e tsebahalang ea sampole ea HPMC (ka tloaelo ligrama tse 1-5) ka har'a crucible 'me u tlalehe boima bo kopantsoeng ba sampole le crucible (m2).
2. Mokhoa oa ashing:
   • Beha crucible e nang le sampole ea HPMC ka seboping sa muffle kapa seboping sa molora.
   • Chesa sebōpi butle-butle ho mocheso o itseng (hangata 500-600 ° C) 'me u boloke mocheso ona ka nako e behiloeng esale pele (hangata lihora tse 2-4).
   • Netefatsa hore lintho tse phelang li tuka ka ho feletseng, ho siea molora feela.
3. Ho pholisa le ho bekha:
   • Ka mor'a hore ts'ebetso ea molora e phethoe, tlosa crucible ho tloha sebōping ho sebelisa li-tong kapa li-crucible holders.
   • Beha crucible le likahare tsa eona ka har'a desiccator ho pholile mocheso oa kamore.
   • Hang ha e se e pholile, leka hape masala a crucible le molora (m3).
4. Palo:
   • Bala palo ea molora oa sampole ea HPMC u sebelisa foromo e latelang: Likahare tsa molora (%) = [(m3 - m1) / (m2 - m1)] * 100
5. Tlhaloso:
   • Sephetho se fumanoeng se emela liperesente tsa molora oa inorganic tse teng sampoleng ea HPMC kamora ho cha. Boleng bona bo bontša bohloeki ba HPMC le palo ea masala a inorganic material a teng.
6. Tlaleho:
   • Tlaleha boleng ba litaba tsa molora hammoho le lintlha life kapa life tse amehang joalo ka maemo a tlhahlobo, boitsebiso ba sampole, le mokhoa o sebelisitsoeng.

Lintlha:

• Netefatsa hore crucible le sekwahelo li hloekile 'me ha li na tšoaetso leha e le efe pele u sebelisoa.
• Sebelisa sebōpi sa muffle kapa sebōpi sa molora se nang le matla a ho laola mocheso ho netefatsa hore mocheso o ts'oanang le liphello tse nepahetseng.
• Tšoara crucible le likahare tsa eona ka hloko ho qoba tahlehelo ea thepa kapa tšilafalo.
• Etsa ts'ebetso ea molora sebakeng se nang le moea o motle ho thibela ho pepeseha ha lihlahisoa tse tukang.

Ka ho latela mokhoa ona, o ka tseba hantle hore na molora o na le lisampole tsa Hydroxypropyl Methylcellulose (HPMC)) le ho hlahloba bohloeki le boleng ba tsona.
