Carboxymethyl cellulose (CMC) is a water-soluble polymer compound modified from natural cellulose. It has good film-forming, thickening, lubricity and dispersibility, and is widely used in the papermaking industry.

Application of CMC in papermaking

The main application of CMC in papermaking includes:

Pulp preparation

In the process of pulp preparation, adding CMC can play the following roles:

Improve the lubricity between fibers, reduce fiber breakage, and increase the beating degree of pulp;

Promote fiber swelling and brooming, and improve the uniformity of pulp;

Improve the water retention of pulp and reduce fiber loss;

Increase the strength of pulp and improve the physical properties of paper.

Sizing

During the sizing process, CMC can play the following roles:

Increase the viscosity and dispersibility of the sizing agent and improve the sizing effect;

Increase the strength and water resistance of the paper;

Increase the smoothness and printability of the paper;

Reduce the fluffing and powdering of the paper.

Coating

During the coating process, CMC can play the following roles:

Increase the viscosity and dispersibility of the coating and improve the coating effect;

Increase the smoothness and glossiness of the coating;

Increase the strength and water resistance of the coating;

Improve the printability of the coating.

Others

CMC can also be used in other aspects of papermaking, such as:

Wastewater treatment: CMC can absorb suspended matter and colloids in wastewater, play a flocculation role, and help purify wastewater;

Auxiliary agent: CMC can be used as a wet strength agent, flame retardant, mildew inhibitor and other auxiliary agents.

Advantages of CMC in papermaking

The application of CMC in papermaking has the following advantages:

Small dosage, significant effect;

Wide source, low price;

Non-toxic, odorless, pollution-free, safe and environmentally friendly;

Good compatibility with other additives, easy to use.
