Lignosulfonate work as water-reducing agent

Lignosulfonate water-reducing agent is a surfactant. Therefore, the mechanism of action is lignosulfonate surfactant effect. Surfactant is an organic compound whose molecules have both hydrophilic and hydrophobic two groups. The hydrophobic groups are various alkyl or alkyl aryl group; hydrophilic group is generally able to dissociate the ionic salts. According to the hydrophilic group of […]

Sodium lignosulfonate used as water reducing agent

Ligosulfonate is a water-soluble multifunctional polymer electrolyte, is a lignosulfonate, with dispersing biological slime, dirt iron oxide, calcium phosphate ability, but also zinc ions, calcium ions to form a stable network compound. Lignosulfonate and calcium lignosulfonate commonly used in the multi-purpose concrete waterproofing agent superplasticizer, concrete after adding water reducer, superplasticizer hydrophobic groups directed adsorbed […]

lignin & Lignosulfonate

Lignin is exist with cellulose in wood, straw and other plant working as binder of cells walls,so naturally has good binding capacity. These is a lot of ways to separate the lignin and cellulose. Most easily way is popular used in China ,they just treated NaOH to separate lignin and cellulose .Cellulose is used as […]

Super Sodium Lignosulfonate

Super Sodium Lignosulfonate is extracted from pure lignin,which is obtained after treated acid to wood or straw,to get rid of cellulose and sugar.It is pure lignin non soluble in water.Then treated by NaOH to get pure sodium lignosulfoate around 95% of lignosulfonate content. Specifications:Solubility 99%min on dry basis,Lignosulfonate 95%min. Function:1.Used in construction as water reducing agent;2.binder […]
