Preparation and storage of CMC aqueous solution

The CMC was mixed with water directly to make a paste solution, which was then used for standby. When the CMC paste is equipped, a certain amount of clean water shall be added in the batching tank with the mixing equipment. When the mixing equipment is open, the CMC shall be slowly and evenly distributed in the batching tank and continuously mixed, so that the CMC and water can be completely mixed, and the CMC can be fully dissolved. The basis for determining the mixing time is: when CMC is evenly dispersed in water and there is no significant large lumpy object, the mixing can be stopped, so that CMC and water are soaked and blended with each other under the condition of standing.

Carboxymethylcellulose CMC was first mixed with dry materials such as white granulated sugar, and then dissolved in water. During the operation, the CMC and the dry materials such as white granulated sugar shall be placed in the stainless steel mixer according to a certain share, and the top cover of the mixer shall be closed to make the materials in the mixer in a closed state. Then, open the mixer and mix CMC and other materials fully. Then, the CMC mixture is slowly and evenly sprinkled into the mixing tank filled with water and continuously mixed.

After CMC is prepared into aqueous solution, it is best to be deposited in containers of ceramic, glass, plastic, wood and other types. It is not suitable to use metal containers, especially containers of iron, aluminum and copper. As a result, if CMC aqueous solution is touched with metal container for a long time, it will simply lead to the problem of degeneration and viscosity reduction. When the CMC aqueous solution coexists with lead, iron, tin, silver, aluminum, copper and some metal substances, the deposition reaction will occur, which will reduce the practical quantity and quality of CMC in the solution. If not production demand, in CMC aqueous solution, try not to mix calcium, magnesium, salt and other substances. The viscosity of CMC solution decreases when CMC solution coexists with calcium, magnesium and salt.

The CMC solution should be used up as soon as possible. If carboxymethylcellulose CMC aqueous solution is stored for a long time, it will not only affect the adhesive function and stability of carboxymethylcellulose CMC, but also suffer damage from microorganisms and mice, and then affect the cleaning quality of the material.
