(HEC)Technology progress of hydroxyethyl cellulose, cellulose ether industry?

Nature of hydroxyethyl cellulose

Hydroxyethyl cellulose solutions can form transparent membranes with nonionic interactions and good nonionic properties. High temperature water solubility: methyl cellulose (MC) dissolved in cold water only compared. Hydroxyethyl cellulose soluble in water, soluble in cold water can not occur or high temperature boiling boiling, thus has a wide range of solubility and viscosity characteristics, and non-thermal gluing. Salt resistance: due to its non-ionic type, can coexist with other water-soluble polymers, surfactants and salts in a wide range. Water retention, smoothness and film formation: its water retention is double than methyl cellulose. With excellent flow regulation and good film formation, water loss, solubility, colloidal protection.HEC

Emulsion coating

Hydroxyethyl cellulose is the most common latex paint thickener. The invention is characterize by significant adhesive effect, good color, film formation and storage stability. It is well compatible with the materials of other compositions (such as pigments, additives, fillers and salts). Hydroxyethyl cellulose thickening coating has good rheological properties at different shear rates and pseudoplasticity. Construction method can draw, roll, spray paint. Polymer polymeric hydroyethyl cellulose synthetic resin has dispersion, emulsification, suspension, and polymerization or copolymer stability and can be use as protective colloids. It has the characteristics of strong dispersion ability, thin particle “film”. Thin particle size, uniform shape, loose shape, good fluidity, good product transparency, convenient processing and so on. Since hydroxyethylcellulose can be dissolved in cold and hot water, the gel temperature is not require and is more suitable for various polymerization reactions.HEC
