Application and contraindication of carboxymethyl cellulose
The sodium carboxymethyl cellulose is directly mixed with water to prepare a paste-like glue solution, and then used. When equipped with sodium carboxymethyl cellulose paste, first participate in a certain amount of clean water in a mixing tank with mixing equipment.
With the mixing equipment open, slowly disperse the sodium carboxymethylcellulose into the batching tank and keep mixing. Make the sodium carboxymethylcellulose and water thoroughly blend, and the sodium carboxymethylcellulose can fully dissolve.
The basis for determining the mixing time is: when sodium carboxymethyl cellulose is uniformly dispersed in water, and there is no significant large agglomerate.
Then, the mixing can be stopped, and the sodium carboxymethyl cellulose and water can be saturated with each other and blend with each other in a standing state.
Carboxymethylcellulose sodium is mix with boring materials such as caster sugar in a dry manner, and then dissolve in water. When operating, first the sodium carboxymethylcellulose and boring materials such as white sugar according to a certain proportion.
Place it in a stainless steel mixer, close the top cover of the mixer, and keep the materials in the mixer in a closed state.
Next, turn on the blender and mix the sodium carboxymethyl cellulose and other materials.
Then, the mix sodium carboxymethylcellulose mixture is slowly and uniformly spray into a batching tank fill with water, and continuously mix.
When using sodium carboxymethyl cellulose in liquid or slurry foods, it is best to homogenize the mixture.
In order to obtain more delicate arrangements and stability. The pressure and temperature use during homogenization should be determine according to the characteristics of the material and the quality requirements of the product.
After the sodium carboxymethyl cellulose is prepare into an aqueous solution, it is best store in ceramic, glass, plastic, wooden and other types of containers.
Metal containers, especially iron, aluminum, and copper containers should not be used for storage. Because, if the sodium carboxymethyl cellulose aqueous solution is in long-term contact with the metal container, it will simply cause the question of deterioration and viscosity decrease.
When the aqueous sodium carboxymethylcellulose solution coexists with lead, iron, tin, silver, aluminum, copper, and some metal substances, a sedimentation reaction will occur, reducing the practical quantity and quality of sodium carboxymethylcellulose in the solution.
If it is not require for production, try not to mix calcium, magnesium, salt and other substances in the aqueous sodium carboxymethyl cellulose solution.
Because when the sodium carboxymethyl cellulose aqueous solution coexists with calcium, magnesium, common salt and other substances, the viscosity of the sodium carboxymethyl cellulose solution will decrease.
