Hydroxyethyl Cellulose powder Usage and Synthesis.

Hydroxyethyl cellulose is a kind of thickener, binder, emulsifier, suspending agent, film-forming agent, water-retaining agent, anticorrosive agent and stabilizer widely used in the fields of construction, daily chemicals and petroleum extraction.

In emulsion paint, hydroxyethyl cellulose can improve the viscosity of the paint, as well as emulsification, dispersion, stabilization and water retention.

In agriculture, hydroxyethyl cellulose can be used as an adhesive and thickener for water-based sprays, which reduces the drifting of chemicals and improves the use of foliar sprays. In fire protection, hydroxyethyl cellulose can be used as a thickener for fireproof materials.

The method of preparing hydroxyethyl cellulose includes the preparation of alkali cellulose, crushing, reacting to produce a crude product, washing, neutralization, cross-linking aging reaction, washing, dehydration, drying and other processes.

Uses of Hydroxyethyl Cellulose powder.

Hydroxyethyl cellulose is used as a dispersing agent for the polymerization of polystyrene and polyvinyl chloride, as well as a water-based gel fracking fluid for fracking and oil extraction. It can also be used as emulsion thickening agent in paint industry, moisture-sensitive resistor in electronics industry, and cement resisting agent and moisture retaining 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, paper making, medicine, health, food, cigarette, pesticide and fire extinguishing agent.

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 petroleum extraction and machinery industry.

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, also used as a hydrophilic gel, skeleton materials, the preparation of skeleton type of sustained-release preparations, but also can be used in the role of food for stabilizers and so on.

Preparation of Hydroxyethyl Cellulose powder.

Product method of Bulk Hydroxyethyl Cellulose 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 and drying, grinding powder, to get low-salt hydroxyethyl cellulose.
