Product Description
Sodium Carboxymethylcellulose sodium,White powder.Density 0.5-0.7 g/cm ³, almost odorless, tasteless, hygroscopic. Easy to disperse in water into a transparent colloidal solution, insoluble in organic solvents such as ethanol. The pH of 1% aqueous solution is 6.5 ~ 8.5, when pH>10 or <5, the viscosity of glue is significantly reduced, and the performance is best when pH=7. Stable to heat, the viscosity rises rapidly below 20 ° C, changes slowly at 45 ° C, and long-term heating above 80 ° C can denature its colloid and significantly decrease its viscosity and performance. Easily soluble in water, the solution is transparent; In alkaline solution is very stable, in the case of acid is easy to hydrolysis, PH value is 2-3 when precipitation, in the case of polyvalent metal salts will also react precipitation.
