hydroxyethyl cellulose

الوصف

Hydroxyethyl Cellulose (HEC), chemical formula (C2H6O2)n, is a white or light yellow, odorless, non-toxic fibrous or powdery solid. Since HEC has good properties of thickening, suspending, dispersing, emulsifying, bonding, film-forming, protecting moisture and providing protective colloid, it has been widely used in oil exploration, coatings, construction, medicine, food, textile, papermaking and polymer Polymerization and other fields. Hydroxyethyl Cellulose Ether can be used in construction products such as concrete mixes, fresh mortar, gypsum plaster or other cements, etc., to retain water during construction before they set and harden. In addition to improving the water retention of building products, hydroxyethyl cellulose also prolongs the correction and open time of plaster or mastic. Can reduce skinning, slipping and sagging. Thus, the construction performance can be improved, the work efficiency can be increased, and time can be saved. At the same time, the capacity expansion rate of the stucco can be improved, thereby saving raw materials.
