The company is mainly engaged in the comprehensive development, production and
sales of dyeing, chemical and concrete admixture products, Products are widely used in pesticides, building materials, printing and dyeing, ceramics, refractories, rubber and other industries.
Among them, the monthly production and sales volume of lignin series products is 5000
tons, and the product quality is stable and reliable.
In recent years, this series of products
have established long-term, stable and friendly cooperative relations with many customers
at home and abroad.
Main products of the company: sodium lignosulfonate, calcium lignosulfonate, alkaline lignin, diffusing agent NNO,carboxymethyl cellulose, concrete air entraining agent, sodium gluconate retarder.

Sodium lignosulfonate
It is produced by reed as raw material and produced by low pollution technology,sodium
lignosulfonate is with good solubility, high surface activity and dispersing ability.It is a
sulfonate derivative contents benzoic acid and carboxyl.It’s adhesion, dispersion and
chelation are widely used in various industries to improve its physical and chemical
properties, save costs and improve efficiency.

Mainly export for Concrete:
Polycarboxylate superplasticizer is a new type of water reducing agent. The water
reduction rate is generally around 20%, but it has high requirements for cement and sand of
concrete.If the mud content in the sand is slightly larger, the polycarboxylate superplasticizer has a water reduction rate of 0.However, the technical team found that when using polycarboxylate superplasticizer’s dosage is 6% of weight with sodium lignosulfonate’s dosage 4%-6%,the water reduction rate will reach the most ideal water reducing ratio and the cost of concrete admixture is also the most economical.Because of the characteristics of calcium and magnesium ions in Sodium lignosulfonate, it is easy to occur precipitation and discoloration when mixed with polycarboxylate superplasticizer.

Other Application:
1. Concrete water reducer: it can adsorb and disperse cement and improve various
physical properties of concrete.
2. Coal water slurry additive: adding this product during the preparation of coal water
slurry can improve the output of high mill, maintain the normal condition of pulping system, reduce the power consumption of pulping, increase the concentration of coal water slurry, reduce the 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 and ceramic green 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 body strength can be increased by more than 20% - 60%.
4. Filler and dispersant for dye industry and pesticide processing: it can increase the
color power of dyes, color more evenly, and shorten the grinding time of dyes;
5. Filler, dispersant and suspending agent in pesticide processing: greatly improve the
suspension rate and wettability of wettable powder.
6. Binder for powder and granular materials: it can obtain good effects such as high
strength, good stability and lubrication of molds in the balling of mineral materials.
7.Dilution dispersant and 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.
