Molekuli: C2H6O2 xCH4O x PhEur 2002 isobanura hydroxyethylmethylcellulose nk'igice cya O-methylated, igice cya O-hydroxymethylated cellulose. Ibisobanuro bitandukanye bigaragazwa hakurikijwe ubukana bugaragara muri mPas y'umuti w'amazi wa 2% w/v kuri 20°C.
Uburemere bwa molekile: PhEur 2002 isobanura hydroxyethylmethylcellulose nk'igice cya O-methylated, igice cya O-hydroxymethylated cellulose. Ibisobanuro bitandukanye bigaragazwa hakurikijwe ubukana bugaragara muri mPas y'umuti w'amazi wa 2% w/v kuri 20°C.

Ibiranga by'ingenzi bya hydroxyethyl methyl cellulose (HEMC) ni ibi bikurikira:

1. Gushonga: bishongeshwa mu mazi no mu bintu bimwe na bimwe by’umwimerere, HEMC ishobora gushonga mu mazi akonje, ingano yayo ntarengwa igenwa gusa n’ubushyuhe, gushonga gutandukana bitewe n’ubushyuhe, uko ubushyuhe bugabanuka, niko gushonga kuba kwinshi.

2. Ubudahangarwa bw'umunyu: Ibicuruzwa bya HEMC ni eteri za cellulose zitari ionic kandi si polyelectrolytes, bityo iyo hari imyunyungugu y'icyuma cyangwa electrolytes organic, biba bihamye mu bisubizo by'amazi, ariko kongeramo electrolytes nyinshi bishobora gutera gellation no kugwa.

3. Ibikorwa byo hejuru: Kubera ko umuti w'amazi ufite imikorere yo hejuru, ushobora gukoreshwa nk'ikintu kirinda koloidi, emulsifier na dispersant.

4. Jeli y'ubushyuhe: Iyo umuti w'amazi wa HEMC ushyushye ku bushyuhe runaka, uba utagaragara neza, jeli, kandi ugakora amazi, ariko iyo ukonjeshejwe buri gihe, ugaruka ku buryo bwawo bwa mbere, maze iyi jeli n'imvura bibaho. Ubushyuhe bushingiye ahanini ku mavuta yazo, ibikoresho bihagarika, colloids zo kurinda, emulsifiers, nibindi.

5. Kudakora neza kw'imisemburo n'impumuro nke: HEMC ikoreshwa cyane mu biribwa no mu buvuzi kuko idahindukamo imisemburo kandi ifite impumuro nke.

6. Irwanya imiyoboro: HEMC ifite ubushobozi bwo kurwanya imiyoboro kandi ikagira ubushobozi bwo kuguma mu buryo bwiza mu gihe kibitswe igihe kirekire.

7. Gutuza kwa PH: Ubushobozi bwaHEMCumuti w’amazi w’umusaruro ntugira ingaruka cyane kuri aside cyangwa alkali, kandi agaciro ka pH kari hagati ya 3.0 na 11.0.

Imikoreshereze: Hydroxyethyl methyl cellulose ishobora gukoreshwa nk'ikintu kirinda colloid, emulsifier na dispersant bitewe n'imikorere y'amazi mu isanzure. Urugero rw'imikoreshereze yayo ni uru rukurikira: Ingaruka za hydroxyethyl methyl cellulose ku miterere ya sima. Hydroxyethyl methylcellulose ni ifu yera idahumura, idasembuye, idahumanya ishongera mu mazi akonje kugira ngo ikore umuti usobanutse kandi utose. Ifite imiterere yo gukomera, gufatanya, gukwirakwiza, gukurura, gukora filime, guhagarika, gukurura, gukora gelling, gukora ku buso, kubika ubushuhe no kurinda colloid. Bitewe n'imikorere y'amazi mu buso, ishobora gukoreshwa nk'ikintu kirinda colloid, emulsifier na dispersant. Umuti w'amazi wa Hydroxyethyl methyl cellulose ufite ubushobozi bwo kuvura amazi neza kandi ni ikintu kibungabunga amazi neza cyane.
