Hydroxyethyl Cellulose et ethyl Cellulose

I. basic conceptibus

Hydroxyethyl Cellulose (HEC), hydroxyethyl Cellulose (HEC) est naturalis polymer compositis, solet adeptus aherification de Cellulose. Et hydroxyethyl (-ch2ch2oh) coetus introducitur in moleculo, dans eam bonam solubility, crasso, gelling et superficiem operationem. Hec late usus est in multis agros ut coatings, stibio, detergents, cibum, medicina et constructione industrias.

Ethyl Cellulose (EC) ethyl Cellulose (EC) sit aethere compositis ex natura cellulosose. Dissimilis HEC, et Ethyl (-c2h5) coetus introducta in Molecule of EC pro hydroxyethyl coetus. Hoc est relative pauper solubility et plerumque solutum in organicis solvents sed insolubilis in aquis. EC communiter in industrias ut pharmaceuticals, coatings et adhesives, et incredit, stabilization et film, formatam munera.

II. Differentias in eget structuram et solubility

Donec structuram:
Et Molecular structuram de HEC formatur per modificat cellulosis moleculis per hydroxyethyl (Ch2ch2oh) substitutione coetus. Hoc modificatio facit hec hydrophilic et potest esse bene dissolvi in ​​aqua.
In EC Molecule, ethyl coetibus (C2H5) Restituo quidam hydroxyl coetibus in Cellulose, quae facit eius moleculis hydrophobic et male solutum in aquam, plerumque solutum in organicis solvits.
Solubility:

Hec facile solutum aqua praesertim calida aqua et solubility ad mocecular pondus et gradus hydroxylation. Ob eius aqua solubility, hec est saepe in condicionibus, ubi aqua solubility requiritur, ut coatings, thestuben, etc.
Eco habet pauper solubility in aqua, sed habet bonum solubility in organicum solvents ut Vocatus solvents et ketone solvent. Ideo EC saepe in organicum solvironments ut a Thickener aut film pristini.

III. Application agri

Applicationem HEC;
Coatings: HEC adhibetur ut a Thickener et Rheology Modifier ad aqua-fundatur coatings, quod potest amplio floris, suspensionem et anti-praecipitatio proprietatibus coatings.
Cosmetics, in stibio industria, hec est saepe usus est in products ut lotions, shampoos et cutis crepito ut a Thickener, emulsifier et moisturizer.
Medicine: HEC est etiam in regi, release medicamento apparatu ut a Thickener et gelling agente ad auxilium tardus release of pharmaca.
Construction: in constructione industria, HEC adhibetur ut a Thickener pro caementa vel cæmento ad amplio constructione perficientur, ut extendens aperta tempore et meliorem operabilitatem.

Application of EC:
Pharmaceuticals: Ethyl Cellulose est saepe usus est in pharmaceutical agro, praesertim in imperium-release medicamento apparatu, ut a medicamento carrier, film coating, etc.
Coatings et adhesives: in coatings industria, EC saepe usus est in Thickener et film pristini. Potest crescere crassitiem et augendae tempestas resistentia.
Food: EC est etiam in cibum agri, maxime ut a Thickener et stabilitor, et adhibetur in cibis ut gelata et Candy.
COLORSICITIA: EC adhibetur in medicamine ad augendam viscosity et stabilitatem emulsorum, et quoque potest esse sicut cutis cura ingrediens.

IV. Euismod collatio

Crasso:
Tum HEC et EC boni crassis effectus, sed HEC ostendit fortis irradatus aqua, praesertim idoneam ad Aqueum systems. EC ostendit magis incredit effectus maxime in organicis solvents debitum ad eius hydrophobicity.

Solubility et stabilitatem:
HEC est aqua solubility et princeps solubility stabilitatem, ita late in aqueous systems. Eco est pauper solubility et magis in organicum solvents vel anhydrous systems.

Rheologiam:
Rheologia proprietatibus HEC solutions variantur diversis concentratione solet typical non Newtoniana fluidi morum. EC solet habet relative assidue, praesertim in organicum solvents.

Hydroxyethyl Cellulose (HEC) et Ethyl Cellulose (EC) sunt duo communi cellulosa derivationes, se cum unique corporis et eget proprietatibus et lateque de applications. HEC Aquam solubility et crasso proprietatibus faciunt late usus est in aqua-fundatur ratio, ut coatings, stibio, et medicina. EC Saepe in organicum solventum systems, ut pharmaceuticals, coatings, adhesives, etc, debitum ad optimum solubility et hydrophobicity. Quod electio ex duobus debet determinari secundum specifica applicationem requisita et genus solvendo usus.
