1. products introduction:

 

Naphthalene sulphate formaldehyde is light yellow to yellow-brown powder, an anionic surfactant. It is soluble in water, acid, alkali and hard water, good dispersion properties. With protein and polyamide fibers have affinity. Mainly used to coloring for vat dyes, reactive dyes, acid dyes, acid staining pad or pigment pad dyeing of the dispersing agent, as a auxiliaries for vat dyes's powder or sizing agent. Also used staining to levelling agent and auxiliary tanning agent in leather industry.

 3. Applications:

 

Sodium Naphthalene Formaldehyde produces concrete with extremely workable characteristics referred to as high slump. PNS also allows concrete to be produced with very low water/cement ratios at low or normal slumps.
Sodium Naphthalene Formaldehyde is ideal for use in prestress, precast, bridge deck or any concrete where it is desired to keep the water/cement ratio to a minimum and still achieve the degree of workability necessary to provide easy placement and consolidation .
