Uses and synthesis of Hydroxyethyl Cellulose powder

Hydroxyethyl Cellulose powder is white or slightly yellow, odourless, tasteless and easy flowing powder.Hydroxyethyl Cellulose CAS 9004-62-0 is soluble in both cool water and hot water, and is generally insoluble in most organic solvents.Viscosity changes are small in the range of pH 2-12, but viscosity decreases beyond this range. Viscosity decreases.

Applications / Functions of Hydroxyethyl Cellulose powder

1. Hydroxyethyl Cellulose Raw Materials Used as a dispersant for the polymerisation of polystyrene and polyvinyl chloride in water-based gel fracking fluids for fracking for oil.
2. It is used as thickener and filter loss reducer for water-based drilling fluid and completion fluid, and has obvious thickening effect in salt water drilling fluid.Hydroxyethyl Cellulose powder can also be used as filter loss reducer for oil well cement. It can cross-link with polyvalent metal ions to form gel.
3. It can be used as surfactant, colloid protection agent, emulsion stabiliser for vinyl chloride, vinyl acetate and other emulsions, viscosity builder, dispersing agent, dispersion stabiliser of latex.

Hydroxyethyl Cellulose Raw Materials Used as surfactants, emulsion thickeners, colloid protection agents, fracturing fluids for petroleum extraction, and dispersants for polystyrene and polyvinyl chloride.

Hydroxyethyl Cellulose CAS 9004-62-0 Surface activity, thickening, suspension, adhesion, emulsification, film-forming, dispersion, water retention and protection in drug solid and liquid preparations.

Physicochemical Property of Hydroxyethyl Cellulose powder

Hydroxyethyl Cellulose powder is white to light yellow fibrous or powdery solid, non-toxic, odourless, easily soluble in water. Insoluble in general organic solvents.Hydroxyethyl Cellulose CAS 9004-62-0 has the properties of thickening, suspending, bonding, emulsifying, dispersing, and retaining water. Can prepare solutions of different viscosity ranges. It has exceptionally good salt solubility for electrolytes.

Production methodprocess of Hydroxyethyl Cellulose powder

1. Soak the raw material cotton fluff or refined meal pulp in 30% lye, take it out after half an hour and press it. Press until the ratio of alkaline water content reaches 1:2.8, and move to the crushing device for crushing. Put the crushed alkali fibre into the reactor. Seal the vacuum, nitrogen filling.
2. After replacing the air in the kettle with nitrogen, press in the pre-cooled ethylene oxide liquid. Under the cooling control 25 ℃ reaction 2h, the crude Hydroxyethyl Cellulose Raw Materials crude. Wash the crude product with alcohol and add acetic acid to adjust the pH value to 4-6.
3. Then add glyoxal to cross-link aging, wash with water quickly, and finally centrifugal dehydration drying, grinding powder, low salt Hydroxyethyl Cellulose CAS 9004-62-0.
