Hydroxyethyl Cellulose Ether Powder Usage and Synthesis.

Hydroxyethyl cellulose (HEC) is a kind of non-ionic cellulose ether widely used in construction, daily chemicals, oil extraction and other fields. It is often used as a thickener in emulsion paints, which can significantly improve the thickening effect, color spreading, film formation and storage stability of the paint.

In addition, HEC has applications in agriculture and fire protection, such as as a suspending agent in water-based sprays and a thickener for fireproofing materials. Hydroxyethyl methyl cellulose (HEMC) is a derivative of HEC, which is also widely used in cosmetics, construction engineering, food processing, petrochemicals, pharmaceuticals, coatings and other fields.

Uses of Hydroxyethyl Cellulose Ether.

Hydroxyethyl cellulose is generally used as a thickener, protective agent, adhesive, stabilizer, and the 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.

It is also used as a stabilizer in foodstuffs. It is used as a dispersant in the polymerization of polystyrene and polyvinyl chloride, etc. It is also used as an emulsifying agent in the paint industry.

It can also be used as emulsion thickening agent in paint industry, moisture-sensitive resistor in electronic industry, cement resisting agent and water retention agent in construction industry. It is also used as glaze and toothpaste adhesive in ceramic industry. It is also widely used in printing and dyeing, textile, papermaking, medicine, health, food, cigarettes, pesticides and fire extinguishing agents.

It is used as surfactant, colloid protection agent, emulsion stabilizer for vinyl chloride, vinyl acetate and other emulsions, as well as viscosity builder, dispersant and dispersion stabilizer for latex.

Widely used in coatings, fibers, dyeing, papermaking, cosmetics, medicine, pesticides and so on. It also has many uses in oil extraction and machinery industry.

Used as surfactant, emulsion thickener, colloid protection agent, oil mining fracturing fluid and polystyrene and polyvinyl chloride dispersant and so on.

Characteristic of Hydroxyethyl Cellulose Ether.

Product Method of Bulk Hydroxyethyl Cellulose Ether Powder.

The raw material cotton staple or refined meal pulp immersed in 30% of the lye, half an hour later removed, for pressing. Press to the alkaline water ratio of 1: 2.8, moved to the crushing device for crushing. Put the crushed alkali fiber 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. 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 drying, grinding powder to get low salt hydroxyethyl cellulose.
