Sodium lignosulphonate

Product Description

Sodium ligno sulphonate is a kind of natural anionic surfactant of high molecular polymer, which is rich in sulfo group and carboxyl and has better water-solubility, surfactivity and dispersion force, made by a process of filtration, inspissation, chemical modification and spray drying with woord as raw material. Sodium ligno sulphonate is widely used in various concrete projects, such as the prilling of concrete admixture, intensifer, suspending agent, dispersant, bulking agent, stabilizing agent, breeze, fertilizer, feedstuff, and foundry of sand mould, performance. (1)Water reducing agent of concrete Sodium ligno sulphonate 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 slurryIf you add sodium ligno sulphonate 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. (3)Filler and dispersant of pesticideSodium ligno sulphonate 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 ceramicsUsually, sodium ligno sulphonate 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. (5)Binder of powdery and granular materials Sodium ligno sulphonate can be used in the press of iron breeze, powered coal, sand mould of cast iron and steel, groud tile, etc. It has highest stability and intensity and also can lubricate matrixes. (6)Dispersant and viscosity depressant Sodium ligno sulphonate can be used as dispersant and viscosity depressant in artsian well to ameliorate the fluidity of transportation of crude oil and reduce energy loss. It can be used as purificant, dispersant, antirust, anlistatig of petrochemicals. (7) Feed additives -sodium ligno sulphonate (8) Leather additives -sodium ligno sulphonate.
