Hydroxy Ethyl Cellulose Ether HEC
HYDROXY ETHYL CELLULOSE [HEC] is made from natural polymer cellulose, a non-ionic water-soluble polymer. It’s effective in thickening, bonding, emulsifying, dispersing, stabilizing, water preserving, forming film and providing protective colloid effect.
As a nonionic surfactant, hydroxyethyl cellulose has the following properties in addition to thickening, suspending, binding, emulsifying, film-forming, dispersing, retaining water and providing protection:
1. HEC is soluble in hot or cold water, and does not precipitate under high temperature or boiling, making it have a wide range of solubility and viscosity characteristics, that is, non-thermal gel;
2. The non-ionic itself can coexist with other water-soluble polymers, surfactants, and salts in a wide range, and is an excellent colloidal thickener containing a high concentration electrolyte solution;
3. The water-retaining capacity is twice as high as that of methyl cellulose, and it has good flow regulation;
4. The dispersing ability of HEC is the worst compared with the recognized methyl cellulose and hydroxypropyl cellulose, but the protective colloid is the strongest.
Applications
1. Used as a protective colloid in water emulsion paint HEC. It can be used in the polymerization of vinyl acetate emulsion to improve the stability of the polymerization system in a wide pH range. In the manufacture of finished products, additives such as pigments and fillers are used to evenly disperse, stabilize, and provide thickening. It can also be used as dispersant for styrene, acrylate, acrylonitrile and other floating polymers.
2. In oil drilling, HEC is used as a thickening agent in various muds required for drilling, well setting, cementing and fracturing operations, so that the mud can obtain good fluidity and stability. HEC improves the mud carrying capacity during drilling and prevents a large amount of water from entering the oil layer from the mud, which stabilizes the production capacity of the oil layer.
3. Used for construction materials and construction materials. Because of its strong water retention capacity, HEC is an effective
thickener and binder for cement mortar and mortar. Adding it to mortar can improve the fluidity and construction performance, and can extend the time of water evaporation Improve the initial strength of concrete and avoid cracks. Used for plastering plaster, cemented plaster and plaster putty can significantly improve its water retention and bonding strength.
