3. Performance and use
Dispersing Agent NNO is light yellow to yellow-brown powder,an anion surface active agent.
Easily soluble in water, acid, alkali and hard water. It has good dispersing property and affinity with protein and polyamide.
Usage: Mainly used for vat dye dyeing, reactive dye dyeing and acid dye dyeing. It can work as dispersant for acid staining pad and pigment pad dyeing; auxiliary for reducing dye powder and slurry. It can also be used in leveling agent in dyeing industry.
1)As dispersining NNO for disperse dye, vat dye, reactive dye, acid dye and leather dye. It has good grinding effect, hydrotropy and dispersibility.
2)As dispersing NNO in textile printing and dyeing industry: pigment pad dyeing of disperse dye;vat acid dyeing of disperse dye; dye for silk and feather mixture; soluble vat dye dyeing;
Etc. also can be used as dispersant for disperse dye and lake making; filler for commercial dye etc.
3)As dispersant in wettable pesticide and herbicide, the dispersibility and solubility of pesticide can be improved.
4)As dispersant in electroplating industry, so that the cladding film can be equal and have a better brightness.
5) As auxiliary tanning agent in leather industry, used together with tanning agent (ratio 1:10) to avoid tanning agent stick with leather. Can also help to disperse dye to get a better appearance in color.
6)As dispersant for paper industry. After adding NNO into wood pulp to avoid the stain from the condensation of asphaltum, resin and other material, 0.2%-0.5% of the wood pulp's weight as dosage is preferable. Can work as precipitator for animal size, 20%-30% of the size's weight as dosage is preferable.
7) As dispersant in rubber industry. Can disperse sulfur,accelerant, anti-aging agent and some filler(like zinc oxide,barium sulphate, calcium carbonate etc). 2%-4% of the dry powder's weight as dosage is preferable. Can make NNO into 10% solution, then grind with others in ball grinder.
8)Also can be used in coating, painting, pigment, carbon black etc.
9)can be used in color lake industry.
4. Packing: 25KG kraft paper bag with plastic lining and 650kg jumbo bag.
5. non-toxic, non-inflammable, non- explosive.
