Basic notitia de hydroxyethyl methylcellulose
Chinese Name: Hydroxyethyl methylcellulose
Anglicus nomen Hymetesose328
Seres alias: hydroxyethyl methyl Cellulose; Hydroxyethyl Methyl Cellulose; hydroxymethyl ethyl cellulosose; II-hydroxyethyl methyl Aether Cellulose
Anglicus aliases: methylhydroxyethylcellosus; Cellulose; II-hydroxyethyl yl aether; HEMC; Tyopur MH [I]
Quaestiones: Hydroymethylmethylcellulose; Hydroxyethylmethylcellosus; Hydroxymethylethylcellulose.

Molecular pondus: Pheur MMII definit hydroxyethyl methylcellosus ut parte o-methylated, ex parte o-hydroxymethylated Cellulose. Viscosity Viscosity Viscosity Viscosity Viscosity Viscosity Viscosity ViCosity Valerius Valerius Valerium II / V Aqueous Solutio ad XX ° C et unitas est MPA s.
Pelagus characteres hydroxyethyl methylcellulose (Hemc) sunt:
I. Solubility: solutum in aquam et quaedam organicum solvents. Hemc potest dissolvi frigidam. Suum summum concentration solum determinari per viscositatem. Solubility variatur cum Viscosity. In inferioribus viscositas maior solubility.
II. Salis resistentia: Hemc products sunt non-Ionic cellulosa aether et non polyelectrolytes, sic sunt relative stabile in aqueum solutions cum metallum sales aut organicum electrolytes est, sed etiam ex electrolytes potest facere galaing et praecipitatio.
III. Superficiem operatio: Ob ad superficiem activae munus aqueum solution, quod potest esse sicut colloidal tutela agente, emulsifier et dispersant.
IV. Thermal Gel: Cum HemC Product Aqueum solutio calescit ad quadam calorem, quod fit opacum, tibia, et praecipitetur, sed cum continue refrigeretur, quod refert ad originale solution statu, et gel et praecipitatio in statum originali, et gel est. Temperature maxime pendeat in illustres, suspendendo AIDS, tutela COLLOIDs, emulsifiers, etc.
V. Metabolicae inertness et humilis odorem et odorem: Hemc late usus est in cibo et medicina quia non erit metabolized et humilis odorem et odorem.
VI. Robigi resistentia: Hemc habet relative bonum rubigo resistentia et bonum viscosity stabilitas durante diu term repono.
VII. PH stabilitas: et viscositas Aqueum solutio HEMC products est vix affectus acidum aut alkali et PH valorem est relative firmum in range of 3.0-11.0.
Application: hydroxyethyl methylcellosa potest esse ut a colloidal tutela agente, emulsifier et dispersant ex eius superficiem activae munus in aqueum solutio. Eius applicationem exemplum est ut sequitur: Influence of Hydroxyethyl Methylcellulose super perficientur de caemento. Hydroxyethyl methylcellosus est odorless, insipidum, non-toxicus alba pulveris quod potest dissolvi in frigore aqua ad formare per transparent visca solutio. Habet habet rationem crasso, binding, dispersio, emulsifying, film-format, suspending, adsorbing, gelling, superficiem activae, maintaining humorem et protegens colloid. Cum aqueum solutio habet superficiem activae munus, quod potest esse sicut colloidal tutela agente, emulsifier et dispersant. Hydroxyethyl methylcellosus Aqueum solutio habet bonum hydrophilicity et est efficiens aqua retentione agente.
