Calcium Ligno Sulphonate
Calcium
Lignosulphonate is an anionic surfactant. It is a water-reducing agent in
concrete construction, and an excellent adhesive in refinery application.
In
the oil drilling fields, Calcium lignosulphonate can be used as blocking agent,
and improve the mud fluidity.Calcium lignosulphonate can also be used as embryo
reinforcing agents in the fields of pottery and porcelain and refractory
materials.Calcium lignosulphonate can increase the fluidity of the slurry and
thus to improve the strength of the embryo.
1. main application
A - water-reducing agent : -
* prefabricated or fresh concrete
construction.
* preparation of antifreezing, pump-deliverable water reducing
agent.
* preparation of different type of water reducing agent.
B - adhesive :-
* It is used as mineral powder adhesive to
improve recovery rate in refinery process.
* It is an excellent adhesive for
fireproof products. It can improve the products' strength and prevent
cracks.
* It reduces the viscosity of clay and improves the product yields in
the ceramic fabrication.
* If is added with phenol type additives in
electrolysis, purer precipitates is formed.
* Main performance
1) Water reducing agent of
concrete
Calcium lignosulphonate can reduce more than 8% water
consumption, improve the workability and water of concrete, reduce the initial
heat of hydration of cement.
(2) Additive of coal water
slurry
If you add calcium lignosulphonate in the process of producing
coal water slurry, it can increase the output of the mill, maintain the
normallization of the system, reduce the power consumption, and improve the
thickness of coal water slurry. In the process of gasification, it also can
reduce oxygen and coal consumption, improve the efficiency of cooled coal gas
and reduce the viscosity of coal water slurry to a certain extent so as to make
it advantageous to reserve and transport.
(3) Filler and dispersant of
pesticide
Calcium lignosulphonate can be used in the production of
deflocculant ,dispersant and bulking agent of pesticide to improve the
suspensibility and wettability of wettable powder.
(4) Reinforcing
agent of refractory material and ceramics
Usually, calcium
lignosulphonate can make ceramic atom hard felted to build up the intensity of
ceramics in the manufacturing process of wall brick and firebrick when the
temperature is under 400 degree centigrade, and also can disappear automatically
if the temperature is between 400 and 500 degree centigrade. When its volume is
0.2%-0.8% of the dry adobe material, the intensity of ceramics adobe can
increase more than 20%-60%. But in the manufacturing process, the speed of
temperature elevation can't be too fast in order to avoid spumescence of
surface.
2. package and storage:
* The product comes in the form of powdery. The
powdery form is packed in PE/PP woven bags, 25kg/package.
* keep away from
moisture.
* The product is non-flammable, non-toxic, non-explosive, and can
be stored for a long time.
