Hydroxyethyl cellulose (HEC) is a white or pale yellow, tasteless, non-toxic, fibrous or powdery solid prepared by etherification of alkaline cellulose and ethylene oxide (or chloroethanol). It is a non-ionic soluble cellulose ether. Because HEC has good thickening, suspension, dispersion, emulsification, adhesion, film formation, protection of water and provide protective colloid and other characteristics, has been widely used in oil exploitation, coating, construction, medicine and food, textile, paper making and polymer polymerization reaction and other fields. Screening rate of 40 mesh ≥99%;
Used as adhesive, surfactant, colloid protective agent, dispersant, emulsifier and dispersant stabilizer. It is widely used in coating, ink, fiber, dyeing, paper making, cosmetics, pesticide, mineral processing, oil extraction and medicine.
1, generally used as thickening agent, protective agent, adhesive, stabilizer and the preparation of emulsion, jelly, ointment, lotion, eye cleaning agent, suppository and tablet additives, also used as hydrophilic gel, skeleton material, the preparation of skeleton type sustained release preparation, can also be used for food stabilizer and other functions.
2, used for textile industry sizing agent, electronics and light industry departments of bonding, thickening, emulsification, stability and other additives.
3. Used as thickening agent and fluid loss reducing agent for water-based drilling fluid and completion fluid, it has obvious thickening effect in brine drilling fluid. Also can be used as oil well cement fluid loss agent. Gels can be crosslinked with polyvalent metal ions.
4. This product is used as a dispersant of polystyrene, polyvinyl chloride and other polymerization of petroleum water-based gel fracturing fluid. It can also be used as emulsion thickener for paint industry, humidity sensitive resistor for electronic industry, cement anticoagulant and moisture retention agent for construction industry. Ceramic industry glazing and toothpaste adhesive. Also widely used in printing and dyeing, textile, paper, medicine, health, food, cigarette, pesticide and fire extinguishing agent.
5, as surfactants, colloidal protective agent, vinyl chloride, vinyl acetate emulsion emulsification stabilizer, and emulsion viscosifier, dispersant, dispersant stabilizer, etc. Widely used in coating, fiber, dyeing, paper making, cosmetics, medicine, pesticide and other aspects. In oil exploitation, machinery industry also has many uses.
6. Hydroxyethyl cellulose has surface activity, thickening, suspension, adhesion, emulsification, film formation, dispersion, water retention and protection in solid and liquid pharmaceutical preparations.
7, used for the exploitation of petroleum water-based gel fracturing fluid, polyvinyl chloride and polystyrene polymerization dispersant. It can also be used as emulsion thickener in paint industry, cement anticoagulant and moisture retention agent in building industry, glaze agent and toothpaste adhesive in ceramic industry. Also widely used in printing and dyeing, textile, paper, medicine, health, food, tobacco and pesticides and other industrial fields.
