Hydroxyethyl cellulose (HEC) is a white or light yellow, odorless, non-toxic fibrous or powdery solid. It is prepared from basic cellulose and ethylene oxide (or chloroethanol) by etherification. Non-ionic soluble cellulose ethers. Because HEC has good characteristics of thickening, suspension, dispersion, emulsification, adhesion, film formation, protection of moisture, and protection of colloids, it has been widely used in petroleum extraction, coatings, construction, medicine and food, textiles, papermaking and polymers. Polymerization and other fields.
Function:
Used as adhesive, surfactant, colloid protective agent, dispersant, emulsifier and dispersion stabilizer. It has a wide range of applications in coatings, inks, fibers, dyeing, papermaking, cosmetics, pesticides, beneficiation, oil extraction and medicine.
1.As an additive
Generally used as a thickener, protective agent, adhesive, stabilizer and additives for the preparation of emulsions, gels, ointments, lotions, eye drops, suppositories and tablets, as well as hydrophilic gels, framework materials, It can be used to prepare matrix-type sustained-release preparations and can also be used as a stabilizer in food.
2.As a thickener
It is used as thickener and fluid loss reducer for water-based drilling fluids and completion fluids. The thickening effect is obvious in brine drilling fluids. It can also be used as a fluid loss reducer for oil well cement. It can be crosslinked with polyvalent metal ions to form a gel.
3.As a dispersant
This product is used in fracturing to extract petroleum water-based gel fracturing fluid, polymeric dispersant such as polystyrene and polyvinyl chloride. It can also be used as a latex thickener for the paint industry, a moisture-sensitive resistor for the electronics industry, a cement coagulant and a moisture retention agent for the construction industry.
4, As a surfactant
As a surfactant, colloidal protective agent, emulsion stabilizer for vinyl chloride, vinyl acetate and other emulsions, as well as latex tackifier, dispersant, dispersion stabilizer
