Hydroxyethyl Cellulose Ether powder Classification.

Hydroxyethyl cellulose is a commonly used cellulose ether organic aqueous ink thickener, belongs to the water-soluble non-ionic compounds, has good thickening ability to water, can be degraded by oxygen, acid and enzyme, and can be crosslinked by Cu2+ under alkaline conditions. Stable to heat, no gelation when heated, no precipitation in acidic conditions, good film-forming properties, its aqueous solution can be made into a transparent film, which can be made from alkaline cellulose and ethylene oxide, has the properties of thickening, emulsification, adhesion, suspension, film-forming, moisture retention and protection of colloids.

Uses of Hydroxyethyl Cellulose Ether.

Hydroxyethyl cellulose is generally used as a thickener, protective agent, adhesive, stabiliser and preparation of emulsions, jelly, ointment, lotion, eye cleaner, suppository and tablet additives, but also used as hydrophilic gels, skeleton materials, the preparation of the skeleton type of sustained-release preparations, but also can be used in the food industry for stabilizers and other roles.

Hydroxyethyl cellulose is used as a dispersing agent for the polymerisation of hydroxyethyl cellulose, polystyrene and polyvinyl chloride, etc. It is also used as a thickening agent for emulsification in the paint industry, as a humidity resistor in the electronics industry, as a cement resistor in the construction industry and as a moisture retaining agent. It can also be used as emulsion thickening agent in paint industry, moisture-sensitive resistor in electronic industry, and cement resisting agent and moisture retaining agent in construction industry. Ceramic industry glaze and toothpaste adhesive. It is also widely used in printing and dyeing, textile, paper making, medicine, health, food, cigarette, pesticide and fire extinguishing agent.

It is used as surfactant, colloid protection agent, emulsion stabiliser for vinyl chloride, vinyl acetate and other emulsions, as well as viscosity builder, dispersant and dispersion stabiliser for latex. Widely used in coatings, fibres, dyeing, papermaking, cosmetics, medicine, pesticides and so on. It also has many uses in petroleum extraction and machinery industry.

Pharmacological action of Hydroxyethyl Cellulose Ether.

Product Methods of Bulk Hydroxyethyl Cellulose Ether powder.

The raw material cotton staple or refined meal pulp immersed in 30% of the lye, half an hour after taking out, for pressing. Press until the ratio of alkaline water to 1: 2.8, moved to the crushing device for crushing. Put the crushed alkali fibre into the reactor. Seal the vacuum, nitrogen filling. After replacing the air in the kettle with nitrogen, press in the pre-cooled ethylene oxide liquid. Under the cooling control 25 ℃ reaction 2h, get crude hydroxyethyl cellulose crude product. Wash the crude product with alcohol and add acetic acid to adjust the pH value to 4 ~ 6. Then add glyoxal crosslinking aging, rapid washing with water, and finally centrifugal dehydration and drying, grinding powder, to get low-salt hydroxyethyl cellulose.
