1. product introduction
The lignin sulfonic acid sodium is a kind of anion surface-active
agent made of sulphite whose main raw material is the northeast
white pine, following the process of concentration,
sugar-exclusion,displacement ,etc.
It is used in dyestuffs industry mainly. This product has many
kinds of different function , for instance viscidity control ,
colour adjusted etc., but main function is the scattering of the
dyestuffs, this product has hydrophilic and hydrophobia radicel. It
creates double membrane layers when interacting with the moisture
molecular . prevent the dyestuffs particle from condensing once
again to improve grinding .

3,Operation methods:
1).to use as dispersant,to determine the proportion of the
dyestuffs and dispersant according to the strong degree of the
dispersant, after confirming dispersant consumption,first half of
the lignin sulfonic acid sodium dispersant first and dyestuffs are
mixed until it ends, then put into another dispersant , this will
get a better result than to all put all the dispersant together
once .
2).to use as packing agent , may put in when spray dying or
standardization.
3).the different kinds of dyestuffs or the same variety without the
same factory, should have a test to determine the suitable
dispersant dosage .
4.packaging ,storage and Transportation: the packaging: it has
plastic pellicle inside and exteiorly packed with woven sacks ,net
weight *5kgs each sack.
Storage: it shall be stored in a waterproof,rainproof place to
avoid agglomeration,if there is agglomeration,smashing it or
dissolving it will not affect using effect,the product is harmless
and does not deteriorate in a long term .it’s not a flammable and
explosive substance.
Transportation: it’s suitable for both truck and railway
transportation,without any limit of remnant cargo or full truck ,we
can arrange the consignment for shipment.
