Quid hydroxyethyl Cellulose?
Hydroxyethyl Cellulose (HEC), a album aut pallide flavo, odorless, non-toxicus fibrosum aut pulveream solidum, paratus aherthication de alkaline cellulosa et ethylene et nonionic solutum celluloso. Quia hec habet bona proprietatibus tales ut irrepit suspendendo, dispersio, emulsifying, vinculum, film-formatam, protegens humorem et providing tutela, coatings, quod est late in oleum exploratio, textilia, in medicine et podalis. Polymerization et aliis agris.
Hydroxyethyl Cellulose est late in coatings industria. Lets 'take a inviso quomodo operatur in coatings:
Quid accidit, cum hydroxyethyl cellulosis occurrat aqua, secundum coatings?
As a non-ionic surfactant, hydroxyethyl cellulose has the following properties in addition to thickening, suspending, binding, flotation, film-forming, dispersing, water retention and providing protective colloids:
HEC solutum calidum aut frigida aqua et non praecipitant ad altum temperatus vel ferventis, faciens non lateque solubility et viscosity characteres, tum non-thermal gelling;
Et aquam retention capacity est alterum quod de yl Cellulose, et non habet melius fluxus;
Non-ionic se potest coexistam cum amplis aliis aqua, solutum polymers, surfactants et sales, quod est optimum colloidal Thickener quibus altus-concentration electrolyticis solutiones;
Comparari cum recognovit methyl cellulosose et hydroxypropyl methyl cellulosis, in disperso facultatem HEC est pessimus, sed tutela colloid facultatem est fortissimum.
Quia superficies-tractata hydroxyethyl cellulosose est pulveream vel fibrosum solidum, shandong hedala admonuit ad attendere ad haec puncta cum parat hydroxyethyl cellulosis matri liquor:
(I) Antequam et post addendo hydroxyethyl Cellulose, quod est servanda concursum usque ad solutionem omnino transparent et patet.
(II) oportet esse tardius sorned in miscentes dolium, et non directe coniungere hydroxyethyl cellulosis et hydroxyethyl cellulosa in miscentes dolium in copiosa vel in forma massas et balls.
(III) et aqua temperatus et PH valorem de aqua habere obvious relatione ad dissolutionem hydroxyethyl Cellulose, ita specialis operam debere solvit ei.
(IV) Nunquam addere aliquid alkaline substantiae ad mixtisque ante hydroxyethyl Cellulose pulveris est madens aqua. Reliquum PH tantum madefecissem voluntatem dissolutionem.
(V), quantum fieri potest, addere antifungal agens in antecessum.
(VI) cum per altus-viscositas hydroxyethyl Cellulose, in concentration mater liquor debet esse altior quam 2.5-3% (per pondus), aliter mater liquor difficile ad tractamus.
