The quality standard of modified sodium lignosulfonate is as follows:
light yellow powder
25KG or 600kg/bag
The experiment proves that lignosulfonate is very effective in preventing sandy soil and can also be used as sand fixing agent in desert. The main performances are as follows:
1. Concrete water reducer: Powdery low air entrainment retarding water reducer, which belongs to anionic surfactant, has adsorption and dispersion effect on cement, and can improve various physical properties of concrete. By reducing water consumption by more than 13%, the workability of concrete can be improved, and the initial hydration heat of cement can be greatly reduced. It can be compounded into early strength agent, retarder, antifreeze agent, pumping agent and so on. The liquid admixture compounded with naphthalene series superplasticizer has little precipitation.
2. Coal-water slurry additives: The addition of this product in the preparation of coal-water slurry can increase mill output, maintain the normal condition of slurry-making system, reduce slurry power consumption, and increase the concentration of coal-water slurry. In the process of gasification, oxygen consumption and coal consumption decrease, cold gas efficiency increases, and the viscosity of coal-water slurry decreases and reaches a certain stability. Qualitative and liquidity.
3. Refractories and ceramic body reinforcing agent: In the manufacturing process of large-scale wall and floor tiles and refractory bricks, the raw material particles of the green body can be firmly bonded, and the strength of the dry blank can be increased by more than 20%-60%.
4. Fillers and dispersants for dyestuff industry and pesticide processing: When used as dispersants and fillers for vat dyes and disperse dyes, the dyestuff's dyeing power can be increased, the dyeing is more uniform, and the grinding time of dyes can be shortened; in pesticide processing, they can be used as fillers, dispersants and suspension agents, which can greatly improve the suspension of wettable powders. Rate and wettability.
