Sodium Lignosulphonate
Character
The product is modified nature lignin product,
taking on powder, having a little fragrance, no poisonous, no harmful. Have a good moisture
absorption ability, water solubility and high chemical stability, at the same
time, Fair absorbability, dispersion, and humidification and Lubrication. Used as MJ-3
water reducing admixtures taking on the feature of small dosage、high reducing rate、low gas
content、good workability and convenience. The product attribution and value is superior to the
equivalent, and the economic efficiency is notable.
Usage
The
product can be used as water –reducers in the field of concrete admixtures. It
could lower the mix water requirements, promote the workability of concrete
mix, and reduce formulation cost, and so on.
The
product can be used as embryo reinforcing agent in the fields of pottery and
pottery and porcelain and refractory materials .they can increase the fluidity
of the slurry and improve the strength of the embryo.
0.2-0.3% mix amount in concrete is recommend
(according to the experiment of customer).
Notice
The product is packed by plastic bags ,it should Guard
against exposes to the sun、damp proof、Keep in
a dry place.
Long-term storage does not change the quality of
product, if has the hard lump, may match the water-soluble fluid or smash, does
not affect the use. This instruction booklet data only supplies for the
reference, the actual amount used should take the empirical datum as.
Packing
and transportation
