the Sodium Carboxymethyl Cellulose(CMC) is an expansion in water solution, the particles form a strong involucre or plastic coating so that the particles scattered difficulty resulting in dissolution difficulty.
Hydroxy ethyl cellulose (HEC) is a non-ionic water-soluble polymer, white or almost white, odorless, fand ree-flowing granular powder.
The cellulose ether is a polymer compound having an ether structure made of cellulose, and each glucosyl ring in the cellulose macromolecule contains three hydroxyl groups, a primary hydroxyl group on the sixth carbon atom, and a second or three carbon atoms.
Sodium carboxymethyl cellulose (CMC) is a cellulose derivative, an ionic cellulose gum, and owing to its unique thickening, suspending, adhesion, and water retention properties, is widely used in various industrial fields.
Paint additives are used in very small quantities, but can significantly improve the properties of paints, so has become an indispensable part of paints – Hydroxyethyl Cellulose in water-based paints. The thickener is a rheological additive. It not only can thicken the paint and prevent sagging in construction, but also can give the paint excellent mechanical properties and storage stability. For the water-based paint with low viscosity, Hydroxyethyl Cellulose is a very important class of additives.
Both HPMC and MHEC serve essential functions in cement-based and gypsum-based construction materials, enhancing workability, adhesion, and durability. While they share similar thickening, water retention, and adhesion-enhancing properties, their thermal stability and hydrophilicity set them apart.
Cellulose probably is the most abundant organic compound in the world which mostly produced by plants.
Cellulose derivatives are extensively used for thickening of pharmaceutical solutions and disperse systems such as emulsions and suspensions.
The Redispersible polymer powder is a special water-based emulsion made by spray drying and a polymer binder prepared mainly based on the vinyl acetate-ethylene copolymer.This article mainly introduces redispersible polymer powder and its performance characteristics in mortar,etc.
Carboxymethyl cellulose is the third most industrially important cellulose derivatives after cellulose xanthate and cellulose acetate, and according to its purity percentage could be used in detergents, food industries, paper coating and laminating, emulsified dyes, drilling muds, pharmacy, cosmetics, health care, etc..
