Dyestuff Auxiliary / Sodium Lignosulphonate  

   Dyestuff Auxiliary/Sodium Lignosulphonate   1.Appearance:dark Brown powder Compose:Modified Lignosulphonate Sodium Ion Type:Negative Ion Solubility:Easily dissolved in water   2. The main technical standard Items Parameter  PH (1percent water solution) 9—10.5 Reductant content,     % 3max Thermal Stability 130degrees  level 4-5  dispersion level in high temperature A-4 Ca2+ Mg2+ content,    ppm  ≤  2000 Insoluble in water,      %     ≤  0.3     3. Performance and use Mainly used in disperse dye and vat dye, can also be diluents in acid dye and dispersion agent in pigment. 1. When used as dispersion agent in pigment, the ratio should be decided according to intensity of dye. After getting the ratio, half of the sodium lignosulphonate should be put in dye and grinded first, after that then add the other half. This will result in a better grinding effect than adding sodium lignosulphonate all one time. When used as filler, it is ok to put t…
