Used as adhesive, surfactant, colloid protecting agent, dispersant, emulsifier and stabilizer etc.. In coatings, printing ink, fiber, dyeing, paper, cosmetics, pesticides, mineral processing, oil production and medicine and other fields has been widely used.
1, generally used as a thickening agent, protective agent, adhesive, stabilizer and preparation of emulsion, gel, ointment, lotion, eye and agent, suppository and tablet additives, also used as hydrophilic gel skeleton material, method for preparing sustained-release preparation, also can be used for food as the stable agent.
2, used in the textile industry, sizing agent, electronic and Light Industry Department of the bonding, thickening, emulsification, stability and other additives.
3, used as a water-based drilling fluid and completion fluid of the thickening agent and reducing agent, in salt water drilling fluid in the thickening effect is obvious. Can also be used as oil well cement of the drop filter. A gel with a polyvalent metal ion crosslinking.
4, this product is used for fracturing method to oil water based gel fracturing fluid, polystyrene and polyvinyl chloride polymerization dispersant. Can also be used as a paint industrial latex thickening agent, electronic industrial humidity resistance, construction of cement retarder and water retention agent. Glazed ceramic industry and toothpaste adhesive. Is also widely used in printing and dyeing, textile, paper, medicine, health, food, cigarettes, pesticides and other aspects of fire extinguishing agent.
5, used as a surface active agent, colloid protecting agent, emulsifying stabilizer combination of vinyl chloride and vinyl acetate emulsion, and emulsion tackifier, dispersant, dispersion stabilizer. Widely used in coatings, fiber, dyeing, paper, cosmetics, medicine, pesticides, etc.. In the oil exploitation, machinery industry also has a lot of use.
6, hydroxyethyl cellulose in pharmaceutical solid and liquid formulations with surface activity, increased thickening, suspension, adhesive, emulsion, film, dispersed, water conservation and provide protective effect.
7, used for the production of water based gel fracturing fluid, PVC and polystyrene and other polymeric dispersant. Can also be used as a paint industrial latex of thickening agent and industrial buildings in the cement anti coagulant and water keep agent, industrial ceramic glazed agent and toothpaste adhesive. Is also widely used in printing and dyeing, textile, paper, medicine, health, food, cigarettes and pesticides and other industrial areas.
Product performance
1, HEC soluble in hot water or cold water, high temperature or boiling does not precipitate, so that it has a wide range of solubility and viscosity characteristics, and non thermal gelation;
2, the non ionic type can be used in a wide range of other water soluble polymers, surfactants, salt, is a kind of high concentration of dielectric solution of a kind of excellent colloidal thickening agent;
3, water retention capacity is higher than that of methyl cellulose, which has good flow regulation;
4, HEC dispersion ability and recognized methyl cellulose and hydroxypropyl methyl cellulose dispersion capacity compared to the worst, but the protective colloid is the strongest.
