Product Description
Sodium lignosulphonate is mainly for concrete mixture as water-reducing additive. Low dosage, low air content, water reducing rate is high, adapt to most kind of cement. Can confected as concrete early-age strength enhancer, concrete retarder, antifreeze , pumping aids etc. Nearly no precipitate product in the liquor additive which is made from the fertilizer binder lignin and naphthalin-group high-efficiency water reducer. The fertilizer binder lignin is suitable for apply to building, dam, high speed way project, etc.

Usage
1,Water reducing agent of concrete
Sodium 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 sodium 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
Sodium 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, sodium 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.
Main Application:
1,water-reducing agent
a. prefabricated or fresh concrete construction.
b. preparation of antifreezing, pump-deliverable water reducing agent.
c. preparation of different type of water reducing agent.
2,adhesive
a. It is used as mineral powder adhesive to improve recovery rate in refinery process.
b. It is an excellent adhesive for fireproof products. It can improve the products' strength and prevent cracks.
c. It reduces the viscosity of clay and improves the product yields in the ceramic fabrication.
d. If is added with phenol type additives in electrolysis, purer precipitates is formed.
