Ukwethulwa kwe-Hydroxyyethyl methyl cellulose hemc

Imininingwane eyisisekelo yeIHydroxYethyl Methyl Cellulose

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

Molecules: C2H6O2 xCH4O x PhEur 2002 defines hydroxyethylmethylcellulose as partially O-methylated, partially O-hydroxymethylated cellulose. Ukucaciswa okuhlukile kuvezwa ngokuya ngokubonakala okusobala ku-MPA s yekhambi le-2% w / v at 20 ° C.
Isisindo samangqamuzana: I-Pheur 2002 ichaza i-hydroxyyethylmerylcellellellellellellellellellellellellellellellellellellellellellellellellellellellellellulose ngokwengxenye ye-O-methylated cellulose. Ukucaciswa okuhlukile kuvezwa ngokuya ngokubonakala okusobala ku-MPA s yekhambi le-2% w / v at 20 ° C.

Izici eziyinhloko ze-hydroxyyethyl methyl celtulose (hemc) yilezi:

I-4 gel ye-Thermal: Lapho umkhiqizo we-hemc we-hemc enamanzi efuthelwa emazingeni okushisa athile, kuba yi-opaque, ama-gels, bese enza okuqhubekayo, kepha kuqhubeka okupholile, le gel kanye nezulu kwenzeka . Izinga lokushisa lincike ikakhulukazi ekuthayiini kwazo, ukumisa izeluleko, ama-colloids avikelayo, ama-emulsifiers, njll.

I-5. I-Metabolic inertness nephunga eliphansi kanye nephunga: I-HEMC isetshenziswa kabanzi ekudleni nasezokwelapha ngoba ayihlangene futhi inephunga eliphansi nephunga eliphansi nephunga eliphansi.

6. I-Antifungal: I-Hemc inekhono elihle le-antifungal kanye nokuqina okuhle kwentokozo ngesikhathi sokugcina isikhathi eside.

7. Ukuqina kwe-PH: ukubonakala kweIpikiliIsixazululo somkhiqizo esinamanzi asithinteki nge-acid noma i-alkali, futhi inani le-PH lizinzile ohlwini lwe-3.0-11.0.

Isicelo: I-Hydroxyyethyl methyl celtule Isibonelo sohlelo lwayo kanjena: Umphumela weHydroxYethyll Methyl Cellulose kwizakhiwo zikasimende. IHydroxYethyl Methylcellulose iyi-powder emhlophe engenamkhawulo, engenambitha, engenamkhawulo, i-nontoxic white ehlanza amanzi abandayo ukwakha isixazululo esicacile, esibonakalayo. Inezakhiwo zokuqina, ukubopha, ukusabalalisa, ukusabalalisa, ukwakha amafilimu, ukumisa amafilimu, ukumisa ama-adsorbing, ukugada, indawo esebenzayo, ukugcina umswakama nokuvikela umswakama nokuvikela ama-colloids. Ngenxa yomsebenzi osebenzayo wekhambi elinamanzi, lingasetshenziswa njenge-ejenti evikela i-colloid, i-emulsifier kanye ne-dispersant. I-Hydroxyyethyl methyllulose isixazululo esinamanzi ane-hydrophility enhle futhi i-ejenti esebenza ngempumelelo.
