After making sodium carboxymethylcellulose into an aqueous solution, it is best to store it in ceramic, glass, plastic, wooden, and other types of containers. Metal containers, especially iron, aluminum and copper containers, are not suitable for storage. If the aqueous solution of sodium carboxymethyl cellulose is in contact with metal containers for a long time, it will cause deterioration and decrease in viscosity. When the aqueous solution of sodium carboxymethyl cellulose is mixed with lead, When iron, tin, silver, aluminum, copper and certain metal substances coexist, a deposition reaction will occur, thereby reducing the actual quantity and quality of sodium carboxymethylcellulose in the solution.
If it is not for production requirements, please try not to mix calcium, magnesium, salt and other substances in the aqueous solution of sodium carboxymethylcellulose, because sodium carboxymethylcellulose solution coexists with calcium, magnesium, salt and other substances, so carboxymethylcellulose The viscosity of the sodium methylcellulose solution will decrease.
The sodium carboxymethyl cellulose aqueous solution provided should be used up as soon as possible. If the sodium carboxymethyl cellulose aqueous solution is stored for a long time, it will not only affect the adhesion function and stability of sodium carboxymethyl cellulose, but also be damaged by microorganisms and pests. , thereby affecting the cleaning quality of the material.
