When it comes to hydroxyethyl cellulose, You will ask: what is this? What is the use? In particular, what is the use in our life? In fact, HEC has many functions, and it has a wide range of applications in the fields of coatings, inks, fibers, dyeing, papermaking, cosmetics, pesticides, mineral processing, oil extraction and medicine. The following is a brief introduction to its functions:
1 .Generally used as thickening agent, protective agent, binder, stabilizer and additive for the preparation of emulsions, jellies, ointments, lotions, eye cleansers, suppositories and tablets, and also used as hydrophilic gels, matrix materials, The preparation of skeleton sustained-release preparations can also be used as a stabilizer in food.
2.Hydroxyethyl cellulose is used as sizing agent in textile industry, bonding, thickening, emulsification, stabilization and other auxiliary agents in electronics and light industry sectors.
3.Hydroxyethyl cellulose is used as a thickener and fluid loss reducer in water-based drilling fluids and completion fluids, and has an obvious thickening effect in saltwater drilling fluids. It can also be used as a fluid loss control agent for oil well cement. It can be cross-linked with polyvalent metal ions to form gels.
4.Hydroxyethyl cellulose is used for fracturing oil water-based gel fracturing fluids, dispersants for polymers such as polystyrene and polyvinyl chloride. It can also be used as emulsion thickener in paint industry, humidity sensitive resistor in electronic industry, cement coagulation inhibitor and moisture retaining agent in construction industry. Glazing and toothpaste adhesives for the ceramic industry. It is also widely used in printing and dyeing, textile, papermaking, medicine, hygiene, food, cigarettes, pesticides and fire extinguishing agents.
5.It is used as surfactant, colloid protective agent, emulsion stabilizer for vinyl chloride, vinyl acetate and other emulsions, as well as latex tackifier, dispersant, dispersion stabilizer, etc. Widely used in coatings, fibers, dyeing, papermaking, cosmetics, medicine, pesticides, etc. It also has many uses in oil extraction and machinery industry.
6.Hydroxyethyl cellulose has surface activity, thickening, suspending, binding, emulsifying, film-forming, dispersing, water retention and providing protection in pharmaceutical solid and liquid formulations.
