钠lignosulphonate

Sodium lignin sulfonate 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 dis- persion force, made by a process of filtration, inspissation, chemical modification and spray drying with cane sugar as raw material. Calcium Lignosulphonate is widely used in various concrete projects, such as the prilling of con- crete admixture, intensifier, suspending agent, dispersant, bulking agent, stabilizing agent, breeze, fertilizer, feedstu- ff and the foundry of sand mould, etc. Index name IndexAppearance Yellow brown powerDispersioncomparing with standard ≥100PH (1% Aq. solution) 791012Moisture% ≤7%Lignin% ≥60%≥80%Water insoluble matter% ≤1.5%Heat stability 130 45A. The key technical indexes B. Main performance 1. Water reducing agent of concrete Reduce more than 8% water consumption, improve the workability and wear of concrete, reduce the initial heat of hydration of cement. 2. Additive of coal water slurry If you add sodium lignin sulfonate in the process of producing coal water slurry, it can increase the output of the mill, maintain the normalization 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 dye and pesticide It is widely used in dye industry to separate and fill dyes. It has many advantages, such as better dispersity and heat stability, less contamination to fibre, less reductibility to azo pigment. At the same time, it can improve the pigmentation and reduce the rubbing time of dyes. It 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 lignin sulfonate 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 ceramic adobe can increase more than 20%-60%. But in the manufacturing process, the speed of temperature elevation cant be too fast in order to avoid spumescence of surface. 5. Binder of powdery and granular materials It can be used in the press of iron breeze, powered coal, sand mould of cast iron and steel, ground tile, etc. It has highest stability and intensity and also can lubricate matrixes. 6. Dispersant and viscosity depressant It can be used as dispersant and viscosity depressant in artesian well to ameliorate the fluidity of transportation of crude oil and reduce energy loss. It can also be used as purificant, dispersant, antirust, anlistatig of petrochemicals. CPacking, storage and transportation 1. Packing: Packed in plastic film bag wrapped with plastic woven sack with a net weight of 25kg each. 2. Storage: Kept in dry and ventilating place, prevent from rain and moisture when storage; if agglomerated, please crush and make it into solution, and its effect will be the same. 3. Transportation: non-toxic, harmless, non-inflammable and non-explosive chemicals, it can be transported in truck and train.
