How to Use Sodium Carboxymethyl Cellulose?

2022-08-01

There are basically two methods for using or dissolving sodium carboxymethyl cellulose: the first is direct dissolution; the second is that sodium carboxymethyl cellulose is fully and evenly mixed with other dry powder materials, and then placed in solution to dissolve. For details, please see the following:

 

1. Mix sodium carboxymethyl cellulose directly with water to prepare a paste-like solution for later use.

When configuring sodium carboxymethyl cellulose paste, first add a certain amount of clean water to the batching tank with a stirring device, and when the stirring device is turned on, sprinkle sodium carboxymethyl cellulose slowly and evenly on the In the batching tank, keep stirring, so that the sodium carboxymethyl cellulose and water are completely fused, and the sodium carboxymethyl cellulose can be fully dissolved.

 

2. The sodium carboxymethyl cellulose is first mixed with other raw materials and other dry raw materials in the form of dry method, and then put into water to dissolve.

During operation, firstly put sodium carboxymethyl cellulose and dry raw materials such as materials in a certain proportion in a stainless steel mixer, close the top cover of the mixer, and keep the materials in the mixer in a sealed state. Next, turn on the mixer and thoroughly mix the sodium carboxymethyl cellulose and other raw materials. Then, slowly and evenly sprinkle the mixed sodium carboxymethyl cellulose mixture into the batching tank filled with water, and keep stirring, and the subsequent operation can be carried out with reference to the above-mentioned first dissolving method.

 

Precautions:

 

1. It takes 10 to 20 hours from when the sodium carboxymethyl cellulose is put into the batching tank and mixed with water until the sodium carboxymethyl cellulose is completely dissolved.

2. When dissolving sodium carboxymethyl cellulose, the reason why it should be spread evenly and stirred continuously is to "prevent the occurrence of agglomeration, agglomeration, and reduction of carboxymethyl cellulose when sodium carboxymethyl cellulose meets water. The problem of dissolving sodium cellulose" and improve the dissolving speed of sodium carboxymethyl cellulose.

3. The stirring time is not the same as the time for the sodium carboxymethyl cellulose to dissolve completely. They are two concepts. Generally speaking, the stirring time is much shorter than the time required for the sodium carboxymethyl cellulose to dissolve completely. The amount of time required depends on the specific situation.

4. If the sodium carboxymethyl cellulose aqueous solution is in contact with the metal container for a long time, it is easy to cause deterioration and viscosity reduction.

5. When the sodium carboxymethyl cellulose solution coexists with calcium, magnesium, salt and other substances, the viscosity of the sodium carboxymethyl cellulose solution will be reduced.

6. The prepared aqueous solution of sodium carboxymethyl cellulose should be used up as soon as possible. If the aqueous solution of sodium carboxymethyl cellulose is stored for a long time, it will not only affect the adhesive properties and stability of sodium carboxymethyl cellulose, but also suffer from The infestation of microorganisms and insects and rodents affects the hygienic quality of raw materials.
