Modified Lignosulphonate Sodium
1. Property.：
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
Sodium sulphate % 0.5
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 this product before spray-dried or after spray-dried. For different kind of pigment and pigment from different manufacturer, it is better to test and get the ratio first before large scale use.
2. as water reducing agent in concrete, has better feature than calcium lignosulphonate. Applicable to dam,reservoir,airport and express way instruction etc.
3. as sanforizing agent in alkaline battery and acid-lead battery to enhance battery’s capacitance and prolong its life span.
4. used in electroplating industry,so that file can be equal and avoid tree-shaped pattern.
5. as auxiliary tanning agent in leather industry.
6. as detergent in boiler
7. as high-level floating agent in gold mining industry.

4. Package: 25KG Woven bag with plastic lining
5. non-toxic, non-inflammable, non-explosive
