Microcrystalline Carboxymethyl Cellulose Sodium Printing Au

Carboxymethyl Cellulose Sodium Paper Making grade CMC

Quick Detail:

Carboxymethyl Cellulose (CMC) is produced by chemical modification of cellulose, the most abundant polymer in nature and a major component of wood and cotton.CMC acts as thickener, rheology modifier, water retention aid, binder, dispersant, floating aid, etc. This wide range of properties makes CMC virtually useful everywhere water is involved in a process and more typically in ceramics, coatings, detergency, drilling fluids, food, mining, paper making , textiles printing.

CMC is a high-efficiency paper-making auxiliary, and features good moisture retention, dispersiblity

Description:

In paper making , CMC is used in making pulp so as to improve the retention rate and increase humidity and strength; when used in surface sizing, CMC can improve internal adhesion, decrease printing dust and enhance printing quality as molding reagent. In paper coating, CMC also helps the dispersion and fluidity of paint, improves appearance of paper and smoothness, upgrades optical performance and printing adaptability.

Addition: 0.3-1.5%.

·Increase the surface strength and abrasion resistance of paper

Applications:
