It is a water-soluble cellulose derivatives made by reacting cellulose with sodium hydroxide and monochloroacetic acid.

Paper-making grade CMC is used in the pulp and paper industry to improve the efficiency of the paper-making process and to enhance the properties of the paper, including strength, porosity, and surface smoothness. It is commonly used in the production of various types of paper, including newsprint, writing paper, and packaging materials.

In the paper-making process, paper-making grade CMC is typically added to the pulp slurry before it is formed into sheets, and it is used in concentrations ranging from 0.01 to 1% by weight of the dry pulp. It can also be added as a surface sizing agent, applied to the surface of the paper after it has been formed.

How To Use Paper-making Grade CMC?

Paper-making grade CMC (Carboxymethyl Cellulose) is typically used as an additive in the paper-making process to improve the retention and drainage of pulp fibers, as well as to enhance the properties of the paper. Here are some general guidelines on how to use paper-making grade CMC:

01.

Determine the concentration: The recommended concentration of CMC in paper-making typically ranges from 0.01 to 1% by weight of the dry pulp, depending on the desired effect.

02.

Add to the pulp: CMC should be added to the pulp slurry during the paper-making process, typically after the pulp has been beaten and refined. It is important to add CMC slowly and mix thoroughly to ensure that it is evenly dispersed.

03.

Mix thoroughly: Once the CMC has been added, the pulp slurry should be mixed thoroughly to ensure that it is well dispersed and the CMC is fully dissolved.

04.

Adjust pH: The pH of the pulp slurry may need to be adjusted to ensure that the CMC is fully activated and effective.

05.

Test: It is important to test the paper to ensure that it has the desired properties, such as good strength, porosity, and surface smoothness.

There are several advantages of using paper-making grade CMC (Carboxymethyl Cellulose) in the paper-making industry, including:

Retention and drainage aid:

Paper-making grade CMC can improve the retention and drainage of pulp fibers during the paper-making process, resulting in better efficiency and reduced pulp losses.

Enhance paper properties:

CMC can improve the strength, porosity, and surface smoothness of paper, resulting in higher quality products with improved printing and writing properties.

Cost-effective:

Paper-making grade CMC is a relatively inexpensive additive, making it a cost-effective solution for improving the quality of paper products.

Easy to use:

CMC is a water-soluble polymer that is easy to handle and can be added directly to the pulp slurry or applied as a surface sizing agent.

Environmentally friendly:

CMC is a naturally occurring material that is biodegradable and non-toxic, making it an environmentally friendly choice for use in paper-making.
