Paper Making Grade CMC

CMC Paper Grade Introduction

CMC is used in the paper industry for the preparation of coatings for coated paper, and can be used as a wet-end additive, surface sizing agent, etc. This product has excellent water retention, thickening, suspending, and dispersion stability.

1. Applications in Coated Paper

● Controls and regulates the rheology and pigment dispersibility of coatings, increasing the solids content of coatings.
● Enhances the water retention value of coatings, prevents the migration of binders in coatings, thereby improving the leveling properties of coatings and improving coating quality.
● Imparts good stability to coatings, maintaining the homogeneity of the coating system.
● Has good film-forming properties, improving the gloss of the coating.
● Increases the retention rate of whitening agents in coatings, improving paper whiteness.

2. Applications as Wet-End Additives

● Has good dispersibility, which is beneficial to paper forming and improves paper uniformity.
● Improves the internal bonding force of fibers, increasing the physical strength of paper.
● Enhances sizing effect.
● Improves the retention rate of various additives, fillers, and fine fibers.

3. Applications in Surface Sizing

● Increases the paper's napping speed, improving the ink absorption performance of paper.
● Good rheology and film-forming properties, enhancing paper stiffness and smoothness.
●Improves surface strength and breathability, and controls curling.

Controlling the Dosage of Paper-Grade CMC

The application of sodium carboxymethyl cellulose (CMC) needs to be adjusted according to different paper types. Cultural papers prioritize improved printability and strength, while packaging papers require better surface properties and abrasion resistance. Specialty papers may have specific requirements for electrical or filtration properties. Therefore, it is necessary to select the appropriate type and dosage of CMC based on specific needs.
In terms of quality control, CMC (Paper Making Grade) has strict technical specifications. Parameters such as degree of substitution, viscosity, purity, and moisture content must be controlled within specific ranges. These indicators directly affect its performance in the papermaking process; therefore, both manufacturers and users highly value the consistency of product quality.
