Paper Grade Sodium Carboxymethyl Cellulose (CMC)

Paper grade sodium carboxymethyl cellulose (CMC) is widely used in all aspects of the paper industry. It is a product obtained by chemically treating natural cellulose, which has excellent stabilizing, viscosifying and dispersing properties. CMC plays an important role in the papermaking process and has a significant impact on paper quality and performance.

Features and Applications

1️⃣ Stabilizer: CMC is used as a stabilizer in the papermaking process, which can control the viscosity and fluidity of pulp, prevent the sedimentation and delamination of pulp, and maintain the stability of pulp. This helps to improve the uniformity and quality of the paper.

2️⃣ Viscosity enhancer: Since CMC has good water solubility, it can effectively increase the viscosity and adhesion in pulp. This allows the fibers to bond better during paper manufacturing, increasing the strength and tensile properties of the paper.

3️⃣ Water retaining agent: CMC has excellent water absorption performance, which can absorb and fix the moisture in pulp. By controlling the water retention of the pulp, CMC helps prevent water loss from the pulp, improving the moisture retention and flexibility of the paper.

4️⃣ Suspending agent: CMC can be used as a suspending agent in the papermaking process to help disperse and stabilize solid particles in pulp, prevent sedimentation and blockage of equipment, and improve the efficiency and quality of paper manufacturing.

5️⃣ Surface anti-adhesive agent: CMC can be used as a surface anti-adhesive agent in the papermaking process and coated on the paper surface. It can reduce the surface viscosity of the paper, reduce the sticking and curling of the paper, and improve the flatness of the paper and the quality of the printed matter.
