Hydroxyethyl Methyl Cellulose (HEMC) Gel Temperature Testing

Ho hlahloba mocheso oa gel oa Hydroxyethyl Methyl Cellulose (HEMC) ho kenyelletsa ho fumana mocheso oo tharollo ea HEMC e kenang ho eona kapa e etsa hore ho be le gel-like consistency.Thepa ena e bohlokoa lits'ebetsong tse fapaneng, ho kenyeletsoa litlhare, litlolo le lisebelisoa tsa kaho.Mona ke kamoo o ka etsang tlhahlobo ea mocheso oa gel bakeng sa HEMC:

Lintho Tse Hlokehang:

1. HEMC phofo
2. Metsi a silafetseng kapa solvent (e loketseng kopo ea hau)
3. Mohloli oa mocheso (mohlala, bate ea metsi, hot plate)
4. Thermometer
5. Thupa e hlohlelletsang kapa molamu oa makenete
6. Libeake kapa lijana tsa ho kopanya

Mokhoa:

1. Lokisetsa letoto la litharollo tsa HEMC tse nang le likhakanyo tse fapaneng (mohlala, 1%, 2%, 3%, joalo-joalo) metsing a hloekisitsoeng kapa motsoako oa khetho ea hau.Etsa bonnete ba hore phofo ea HEMC e hasane ka ho feletseng ka mokelikeli ho thibela ho phunyeha.
2. Beha e 'ngoe ea litharollo ka beaker kapa setshelo, 'me u qoelise thermometer ka har'a tharollo ho hlokomela mocheso.
3. Chesa tharollo butle-butle u sebelisa bate ea metsi kapa sejana se chesang ha u ntse u susumetsa ka mokhoa o sa khaotseng ho netefatsa hore ho futhumala ho tšoanang le ho kopanya.
4. Sheba tharollo ka hloko 'me u hlokomele liphetoho leha e le life tsa viscosity kapa ho tsitsisa ha mocheso o ntse o eketseha.
5. Ngola mocheso oo tharollo e qalang ho teteana kapa e theha sebopeho se kang sa gel.Mocheso ona o tsejoa e le mocheso oa gel kapa mocheso oa gelation oa tharollo ea HEMC.
6. Pheta mokhoa o mong le o mong oa tharollo ea HEMC ho fumana mocheso oa gel ho pholletsa le mefuta e mengata ea likhahla.
7. Sekaseka lintlha ho tseba mekhoa kapa likamano pakeng tsa mahloriso a HEMC le mocheso oa gel.
8. Ka boikhethelo, etsa liteko tse eketsehileng kapa liteko ho hlahloba phello ea lintlha tse kang pH, letsoai la letsoai, kapa li-additives ho mocheso oa gel oa tharollo ea HEMC.

Malebela:

• Etsa bonnete ba hore phofo ea HEMC e qhalakantsoeng ka ho feletseng ka mokelikeli ho thibela ho kopanya kapa ho se lekane ha gelation.
• Sebelisa metsi a silafetseng kapa solvent e loketseng ho lokisa tharollo ea HEMC ho qoba ho kena-kenana le litšila kapa litšila.
• Hlohlelletsa tharollo ka ho tsoelang pele nakong ea ho futhumatsa ho boloka kabo e tšoanang ea mocheso le ho kopanya.
• Nka litekanyo tse ngata 'me u be le karolelano ea liphetho ho ntlafatsa ho nepahala le ho ts'epahala.
• Nahana ka litlhoko tse khethehileng tsa kopo ea hau ha u khetha likhatiso tsa HEMC le maemo a tlhahlobo.

Ka ho latela mokhoa ona, o ka tseba mocheso oa gel oa tharollo ea Hydroxyethyl Methyl Cellulose (HEMC) mme o fumana lintlha tsa bohlokoa ka thepa ea eona ea rheological le boitšoaro tlas'a maemo a fapaneng.
