Sodium Lignosulfonate
Introduction
(1) Sodium lignosulfonate is a natural polymer, anionic surfactant. It has strong dispersion ability and is suitable for dispersing solids in aqueous medium.
(2) Sodium lignosulfonate is widely used in granulation of animal feed, and refined lignosulfonate is used as dispersant of oil drilling mud; Ore flotation agent, dispersant of slime, dyes and pesticides; It has good chelating ability for heavy metals, especially iron, copper and stannous ions. It is an effective chelating agent.
Features
Lignin sodium precipitation agent (wood pulp) is processed from sulfate pulping waste liquid. It is chemically modified, with medium molecular weight and low sugar content.
As a concrete mixer, it has the characteristics of low ash, low air content and strong cement adaptability. Its most remarkable feature is that there is no precipitation of naphtha in the liquid mixture.
Application
1. Concrete Water Reducing Agent
It is a powdery low air entraining retarding and water reducing agent. It belongs to anionic surfactant. It can adsorb and disperse cement and improve various physical properties of concrete. Reduce water consumption by more than 13%, improve the workability of concrete, and greatly reduce the hydration heat at the initial stage of cement hydration. It can be compounded into early strength agent, retarder, antifreeze, pumping agent, etc. the liquid admixture compounded with naphthalene superplasticizer basically has no precipitation. After adding sodium lignosulfonate into the concrete, the hydrophobic group of the water reducing agent is directionally adsorbed on the surface of the cement particles, and the hydrophilic group points to the aqueous solution to form a single molecule or multi molecule adsorption membrane, so that the cement particles are dispersed due to the mutual exclusion of the same surface charges, and excess water is released from the particles to achieve the purpose of water reduction. At the same time, because the surface tension of water and the interfacial tension between cement particles are reduced, the water consumption is reduced accordingly while maintaining the same fluidity, which also plays the role of water reduction. Water reducing agent can greatly reduce the hydration of concrete, reduce the porosity and increase the compactness of concrete, so as to greatly improve the strength and impermeability of concrete.2. CWS Additives
Adding this product in the process of preparing coal water slurry can improve the output of high mill, maintain the normal condition of pulping system, reduce pulping power consumption, increase the concentration of coal water slurry, reduce oxygen consumption and coal consumption, improve the efficiency of cold gas, reduce the viscosity of coal water slurry and achieve certain stability and fluidity.
3. Refractory & Ceramic Body Reinforcer
In the manufacturing process of large-size wall and floor tiles and refractory bricks, the raw material particles of green body can be firmly bonded, and the dry green strength can be increased by more than 20% - 60%.
4. Fillers & Dispersants For The Dye Industry & Pesticide Processing
When used as dispersant and filler of vat dyes and disperse dyes, it can increase the color power of dyes, color more evenly, and shorten the grinding time of dyes; It can be used as filler, dispersant and suspending agent in pesticide processing to greatly improve the suspension rate and wettability of wettable powder.
5. As Binder For Powder & Granular Materials
Used for pressing iron ore powder, lead-zinc ore powder, pulverized coal and coke carbon powder; Pressing of cast iron and cast steel sand mold; Extrusion molding of mud brick wall and floor tile; In terms of pelletizing of mineral materials, good results such as high strength, good stability and lubrication of molds can be obtained.
6. As Dilution Dispersant & Viscosity Reducer In Drilling
Improve the fluidity of crude oil transportation and reduce energy consumption. In petroleum products, it is used as cleaning agent, dispersant, high alkaline additive, antirust agent, antistatic agent, emulsion viscosity reducer, wax elimination and anti wax agent, etc.
Usage
(1) 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.
(2) 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.
(2) 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.
Caution
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.
