Sodium Lignosulphonate used as oil displacement agent in oilfield
Sodium Lignonsulphonate:
Sodium lignin water reducing agent(wood pulp) is made from sulfite
pulping waste liquor processing under chemically modified form,
with medium molecular weight and low sugar content. Used as
concrete admixtures, features of low ash, low gas content and
strong adaptability for cement, the most significant feature is no
precipitate in the liquid admixture which compound with naphthalene
high-performance water reducer.
Usage:
For Sodium lignin water reducer, recommended amount in the concrete
cement (weight) of 0.2% 0.6%, the user should determine the optimal
dosage through the experiment. Sodium lignosulfonate can be used as
liquid.
The effect of Sodium lignosulphonate is significant when compound
with naphthalene high-performance water reducer. the user should
determine the optimal dosage through the experiment.
Cautions:
When using sodium lignin water reducer, must control the dosage
strictly, effect will not obvious if less, it will affect the early
strength of concrete. When the temperature is below 5 ℃, it is
inappropriate used alone for concrete projects

Packaging and storage
1. Powder products are made of chemical fiber woven bags, lined
with plastic film bags, each bag net weight (40±0.2kg) or
(25±0.2kg) or (750±0.2kg), can also be customized according to
customer requirements.
2. Powder products should be stored in dry and ventilated special
warehouse, products such as damp caking can be crushed or dissolved
into water agent use does not affect the actual effect.
