Indicators of sodium lignosulfonate
The sodium lignosulfonate (sodium lignosulfonate for short) produced by Chenghao Company uses poplar pulp as raw material and is produced using a low-pollution process and is rich in benzoic acid. Sulfonate derivatives of active substances such as base and carboxyl groups, which have good solubility, high surface activity and dispersing ability.
Sodium lignin is widely used as concrete admixture (recommended dosage, adjusted according to local cement conditions), coal-water slurry additive, asphalt emulsifier, reinforcing agent for refractory materials, filler and suspending agent for pesticides , dispersants and fillers for dyes, mud stabilizers for drilling, pelletizing of ceramic bodies, mineral powder, fertilizers and feeds, casting sand molds, etc.
Polycarboxylic acid high-efficiency water-reducing agent is a water-reducing agent that has only emerged in recent years. The tax reduction rate is generally around 10%, but its requirements for cement and sand and gravel are extremely high. If the mud content in the sand and gravel is slightly larger, Polycarboxylic acid exhibits a tax reduction rate of , but research has found that when the amount of polycarboxylic acid and lignin sodium is between: - when the amount of polycarboxylic acid is - and the amount of lignin sodium is -, the tax rate reduction is the most ideal and the cost is the most economical. Due to the characteristics of calcium and magnesium ions, it is easy to cause precipitation and discoloration when combined with polycarboxylic acid.
