Ukwethulwa Komkhiqizo kweHydroxYethyl Methyl Cellulose Hemc

Imininingwane eyisisekelo ye-hydroxyyethylm methylcellulose

Igama lesiShayina: Hydroxyyethyl methylcellulose
Igama lesiNgisi: Hyymetellose328
I-Chinese Alias: I-Hydroxyyethyl methyl cellulose; IHydroxYethyl Methyl Cellulose; hydroxymethyl ethyl cellulose; 2-hydroxyethyl methyl ether cellulose
Ama-English Aliases: Methylhydroxyethylcellellose; Cellulose; 2-hydroxyyethyl methyl ether; Hemc; Tyopur mh [1]
Chemistry: Hydroymethylmethylcellellulose; HydroxyEthylmethylcellellellellellellulose; Hydroxymethylethylcellellose.

I-Molecule: C2H6O2 XCH4O X Pheur 2002 ichaza i-hydroxyethyll methylcellulose njengengxenye ye-O-methylated, ngokwengxenye ye-o-hydroxymesyletated cellulose. Ukucaciswa okuhlukile kuvezwa yinani elibonakalayo le-viscosity elingu-2% w / v atcoul nokhambi ku-20 ° C, futhi iyunithi yi-MPA s.
Isisindo samangqamuzana: I-Pheur 2002 ichaza i-hydroxyethylllylyly methylcellulose njengengxenye ye-O-methylated, ngokwengxenye ye-o-hydroxymesyletated cellulose. Ukucaciswa okuhlukile kuvezwa yinani elibonakalayo le-viscosity elingu-2% w / v atcoul nokhambi ku-20 ° C, futhi iyunithi yi-MPA s.

Izici eziyinhloko ze-hydroxyyethyl methylcellulose (hemc) yilezi:

1. I-Solubity: incibilika emanzini kanye nezinye izixazululo ze-organic. I-Hemc ingachithwa emanzini abandayo. Ukuhlushwa kwayo okuphezulu kunqunywa kuphela ngokubonakala. I-Solubolity iyahlukahluka nge-viscosity. Ukwehlisa ukubonakala, kukhudlwana ukubola.

I-3. Umsebenzi ongaphezulu

I-4 gel ye-Thermal: Lapho umkhiqizo we-hemc we-hemc enamanzi efuthelwa emazingeni okushisa athile, kuba yi-opaque, ama-gels, kanye ne-precipitates, kepha uma kuqhubeka okupholile, kubuyela esimweni se-gel kanye nezulu. Izinga lokushisa ikakhulukazi lincike ekuthayijeleni kwabo, ukumisa izinsizakusebenza, okuvikelayo ama-colloids, ama-emulsifiers, njll.

I-5.

I-6. Ukumelana Nensimu: I-Hemc inokumelana ne-versew enhle kanye nokuqina okuhle kwentokozo ngesikhathi sokugcina isikhathi eside.

Isicelo: I-HydroxYethyl Methylcellulose ingasetshenziswa njenge-ejenti evikelayo ye-colloidal, emulsifier kanye ne-distrisant ngenxa yokusebenza kwayo okusebenzayo kwesisombululo samanzi. Isibonelo saso sohlelo lokusebenza ngokulandelayo: Ithonya le-hydroxyethyll methylcellulose ekusebenzeni kuka usimende. IHydroxYethyl Methylcellulose iyimpuphu ye-White engenamzimba engenamqondo, engenambitha, engeyona into enobuthi engachithwa emanzini abandayo ukwakha isixazululo esibonakalayo se-viscous. Inezici zokuqina, ukubopha, ukusabalalisa, ukusabalalisa, amafilimu, ukumisa, ukumisa ama-adsorbing, ukugcinwa komhlaba, ukugcina umswakama nokuvikela umswakama nokuvikela i-colloid. Njengoba ikhambi lamanzi linomsebenzi osebenzayo ongaphezulu, lingasetshenziswa njenge-ejenti yokuvikela i-colloidal, emulsifier kanye ne-dispersant. I-Hydroxyyethyl Methylcellulose ikhambi elinamanzi amahle i-hydrophility enhle futhi i-ejenti yokugcinwa kwamanzi efanelekile.
