Use of Sodium Lignosulfonate

Sodium Lignonsulphonate:

The properties of lignosulfonates made from different raw materials are different. Compared with the lignin sulfonate made from wheat grass, the lignin sulfonate made from trees has higher molecular weight and better dispersion. The size of the molecular weight of lignosulfonate depends on the raw material itself and the subsequent chemical modification. Under the same degree of sulfonation, the larger the molecular weight, the better the dispersion and suspension, because the larger the molecular weight, the greater the steric hindrance effect, which can prevent the lower layer or transfer of the original drug. The degree of sulfonation refers to the ratio of sulfonic acid group and total molecular weight, some units with millimolar gram ratio, the main reaction of the degree of sulfonation of lignin, the better the sulfonation, the better the water solubility, the high degree of sulfonation of lignosulfonate regardless of acid and base are dissolved well. If the degree of sulfonation is low, the solubility is certainly poor, and some cheap lignosulfonates also contain a lot of alkaline lignin, which affects the solubility of the lignin. Therefore, lignin with a high pH value has poor dispersibility because of its high alkaline lignin content.

Use of sodium lignosulfonate:

1, mainly used as cement water-reducing agent, so that the group of cement diffusion, water analysis, increase its fluidity. Thus reducing mixing water and saving cement. When used in oil drilling mud formulation, it can effectively reduce mud viscosity and shear force, so as to control the flow of drilling mud, keep inorganic soil and inorganic salt impurities suspended in drilling, prevent mud flocculation, and have outstanding salt resistance, calcium resistance and high temperature resistance. Lignosulfonate is a natural polymer with a molecular weight of 1000 ~ 30000. It is made from the production of pulp waste after fermentation to extract alcohol, and then neutralized with alkali, mainly calcium lignosulfonate, sodium lignosulfonate, magnesium lignosulfonate, etc., which is the most widely used calcium lignosulfonate is made of sulfite pulp waste liquid. This kind of water reducing agent raw material source is rich, the manufacturing process is simple, the price is low, in the domestic application is more common, accounting for about 80% of the total production of water reducing agent. However, its effect is not good, has the effect of entraining air and retarding coagulation, belongs to the ordinary water reducer, and the composite use of early strength agent is better.

2, used as concrete water-reducing agent, oil drilling mud dispersant, printing and dyeing diffusion agent, etc. Used as concrete water-reducing agent, oil drilling mud dispersant, printing and dyeing diffusion agent

3, refractory and ceramic body strengthening agent: in the manufacturing process of large wall and firebrick, the raw material particles of the body can be firmly bonded, which can increase the dry strength of the body 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, it can increase the color power of dyes, color more evenly, and shorten the time of dye grinding; 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 powder and granular materials: used for iron ore powder, lead-zinc ore powder, coal powder, coke powder pressure ball; Pressing of cast iron and cast steel sand mould; Mud brick wall and floor tile extrusion molding; High strength, good stability, good lubricating mold and other good results can be obtained in the pellet formation of ore.

6. Used as diluent dispersant and viscosity reducer in drilling; Improve the flow of crude oil transportation and reduce energy consumption. In petroleum products, it is used as cleaning agent, dispersant, high alkaline additive, anti-rust agent, antistatic agent, emulsifying viscosifier, dewaxing and anti-waxing agent.

Packaging and storage

1. Powder products are made of chemical fiber woven bags, lined with plastic film bags, each bag net weight (40±0.2kg) or (25±0.2kg) or (750±0.2kg), can also be customized according to customer requirements.

2. Powder products should be stored in dry and ventilated special warehouse, products such as damp caking can be crushed or dissolved into water agent use does not affect the actual effect.
