Properties Hydroxyethyl cellulose is a white or yellowish powder that is odorless, tasteless and easy to flow. It is soluble in hot water and generally insoluble in most organic solvents. The viscosity changes little in the PH range of 2-12, but the viscosity decreases beyond this range. Uses Hydroxyethyl fiber Chemicalbook is generally used as thickening agent, protective agent, binder, stabilizer, and additive for the preparation of emulsions, gels, ointment, lotion, eye cleanser, suppository and tablets, and is also used as hydrophilic gel, skeleton material, preparation of skeleton sustained release preparations, and can also be used as a stabilizer in food.
HEC powder is a commonly used cellulose ether organic water-based ink thickener. It is a water-soluble non-ionic compound, which has good thickening ability to water, can be degraded by oxygen, acid and enzyme, and can be cross-linked by Cu2+ under alkaline conditions. It is stable to heat, does not gelatinize when heated, does not precipitate under acidic conditions, and has good film formation, and its aqueous solution can be made into a transparent film, which can be formed by the action of alkaline cellulose and Chemicalbook ethylene oxide, with thickening, emulsification, bonding, suspension, film formation, moisture retention and colloidal protection properties. The role of thickener in water-based ink is to thicken. The viscosity of ink increased by adding thickener can improve the physicochemical stability of ink. Due to the increase in viscosity, the rheology of the ink can be controlled during printing. The pigment and filler in the ink are not easy to precipitate, and the storage stability of the water-based ink is increased.
This product is used for fracturing oil water-based gel fracturing fluid, polystyrene and polyvinyl chloride polymerization dispersant. It can also be used as emulsion thickening agent in paint industry, humidity sensitive resistor in electronics industry, cement coagulant and moisture retaining agent in construction industry. Ceramic industry glazing and toothpaste adhesive. It is also widely used in printing and dyeing, textile, papermaking, medicine, health, food, cigarettes, pesticides and fire extinguishing agents. Use as a thickening agent and fluid loss reducer for water-based drilling fluid and completion fluid, the thickening effect is obvious in salt water drilling fluid. It can also be used as a fluid loss reducer for oil well cement. It can be crosslinked with polyvalent metal ions to form gels. It is used as surfactant, colloidal protective agent, emulsifying stabilizer for vinyl chloride, vinyl acetate and other emulsions, as well as viscosifier, dispersant and dispersion stabilizer for latex. Widely used in coating, fiber, dyeing, papermaking, cosmetics, medicine, pesticides and other aspects. It also has many uses in oil extraction and machinery industry.
