Introduction of Hydroxyethyl Methyl Cellulose Hemc

Basic notitiaHydroxyethyl Methyl Cellulose

Chinese Name: Hydroxyethyl Methyl Cellulose
Anglicus nomen Hymetesose328
Seres alias: hydroxyethyl methyl Cellulose; Hydroxyethyl Methyl Cellulose; hydroxymethyl ethyl cellulosose; II-hydroxyethyl methyl Aether Cellulose
Anglicus alias: Methylhydroxyethylcellulose; Cellulose; II-hydroxyethyl yl aether; HEMC; Tyopur MH [I]
Quaestiones: Hydroymethylmethylucellulose; Hydroxyethylmethylcellosus; Hydroxymethylethylcellulose.

Molecules: c2h6o2 xch4o x pheur MMII definit hydroxyethylmethylcellulose ut parte o-methylated, ex parte o-hydroxymethylated Cellulose. In diversis specifications exprimuntur in terms of apparent Viscosity in MPA s II% w / v aqueum solutio ad XX ° c.
Molecular pondus: Pheur MMII definit hydroxyethylmethylcellulose ut parte o-methylated, ex parte o-hydroxymethylated Cellulose. In diversis specifications exprimuntur in terms of apparent Viscosity in MPA s II% w / v aqueum solutio ad XX ° c.

Pelagus characteres de hydroxyethyl Methyl Cellulose (Hemc) sunt:

I. Solubility: solutum in aquam et organicum solvents, HEMC potest dissolvi in ​​frigore aqua, maximum concentration solum determinatur per viscositatem solubility viscositas, minus solubility viscositas, inferioris viscositatem, maioris solubility.

II. Salis resistentia: Hemc products sunt non-Ionic cellulosa aether et non polyelectrolytes, ita in conspectu Domini metallum sales aut organicum electrolytes, sunt relative firmum in Aqueum solutiones, sed etiam ex electrolytes potest facere in Aqueum et praecipitatio.

III. Superficiem actione, sicut aqueum solutio habet superficiem actio munus, quod potest esse ut colloid tutela agente, emulsifier et dispersant.

4. Thermal gel: When the HEMC product aqueous solution is heated to a certain temperature, it becomes opaque, gels, and forms a precipitate, but when it is continuously cooled, it returns to the original solution state, and this gel and precipitation occur . Temperature pendeat maxime in lubricants, suspendendo AIDS, tutela COLLOIDIDS, emulsifiers, etc.

V. Metabolicae inertness et humilis odoris et odor: Hemc late usus est in cibo et medicina, quia non metabolized et humilis odorem et odorem.

VI. Antifungal: Hemc habet bonum Antifungal facultatem et bonum viscosity stabilitas durante diu term repono.

VII. PH Stabilitas: ViscosityPRAETERMENTUMProduct Aqueum solutio est vix affectus acidum aut alkali, et PH valorem est relative stabilis in range of 3.0-11.0.

Application: Hydroxyethyl Methyl Cellulose potest esse sicut colloid tutela agente, emulsifier et dispersant propter superficiem activae munus aqueum solution. Exemplum de eius application est ut sequitur: et effectus hydroxyethyl methyl Cellulose in proprietatibus cementum. Hydroxyethyl methylcellosus est odorless, insipidum, nontoxic albus pulveris, quod solvit in frigore aqua ad formare patet, viscosa solutio. Is est proprietatibus crasso, binding, dispersio, emulsifying, film-format, suspending, adsorbing, gelling, superficies activae, retinens humorem et protegens colloids. Ob ad superficiem activae munus aqueum solutio, quod potest esse sicut colloid tutela agente, quod emulsifier et dispersant. Hydroxyethyl Methyl cellulosis aqueum solutio habet bonum hydrophilicity et est summus efficientiam aqua, retinendi agente.
