ATET Sodium Lignosulfonate Cas No 8061-51-6 For Activated Carbon

Sodium lignosulfonate is used to produce activated carbon

Sodium Lignonsulphonate :

The carbon content of lignin is more than 50%, which is a suitable raw material for carbon production. The preparation of activated carbon has physical activation method and chemical activation method: physical activation method is the raw material carbonization, and then at a certain temperature and steam and carbon dioxide reaction to achieve the purpose of the development of pores, the preparation of activated carbon usually does not need to carry on the late washing impurity, but the required carbonization temperature is generally higher, more than 800℃; Chemical activation method is the activator such as phosphoric acid, zinc chloride and raw materials mixed at different temperatures for activation, the activated carbon to be washed through water to remove impurities, carbonization activation temperature is low, the activated carbon pores are more developed.

Uses of sodium lignosulfonate:

1, mainly used as cement water-reducing agent, so that the group cement diffusion, water analysis, increase its fluidity. Thus reduce mixing water and save cement. When used for oil drilling mud formulation, it can effectively reduce mud viscosity and shear force, so as to control the flow of drilling mud, keep the inorganic soil and inorganic salt impurities suspended in drilling, prevent mud flocculation, and has excellent salt resistance, calcium resistance and high temperature resistance. Lignosulfonate is a natural polymer with a molecular weight of 1000 ~ 30000. It is produced by the waste liquor of the pulp fermentation extracted alcohol, and then neutralized with alkali, mainly calcium lignosulfonate, sodium lignosulfonate, magnesium lignosulfonate, etc., of which the most widely used calcium Lignosulfonate is made of sulfite pulp waste. This kind of water reducing agent raw materials are rich in sources, simple manufacturing process, low price, and more common in domestic application, accounting for about 80% of the total production of water reducing agent. However, its effect is not good, it has the effect of entraining air and retarding coagulation, it is a common water reducer, and the composite use of early strength agent has a better effect.
2, used as concrete water-reducing agent, oil drilling mud dispersant, printing and dyeing diffusion agent. Used as concrete water reducer, oil drilling mud dispersant, printing and dyeing diffusion agent
3, refractory ceramic body reinforcement agent: in the manufacturing process of large walls and refractory bricks, the raw material particles of the body can be firmly bonded, and the dry strength of the body can be increased by more than 20%-60%.
4. Fillers and dispersants for dye industry and pesticide processing: when used as dispersants and fillers for VAT dyes and disperse dyes, the color power of dyes can be increased, the color is more uniform, and the grinding time of dyes can be shortened; It can be used as filler, dispersant and suspension agent in pesticide processing, which greatly improves the suspension rate and wettability of wettable powder.
5, as a binder for powdery and granular materials: used for iron ore powder, lead-zinc ore powder, coal powder, coke powder pressure ball; Pressing of cast iron and steel sand mold; Mud brick wall floor tile extrusion molding; Good results such as high strength, good stability and good lubrication mold can be obtained in ore pelleting.
6. Used as diluent dispersant and viscosity reducer in drilling; Improve the flow of crude oil and reduce energy consumption. It is used in petroleum products as cleaning agent, dispersant, high alkaline additive, anti-rust agent, antistatic agent, emulsifying viscosifier, dewaxing and anti-waxing agent.
