Calcium Lignosulfonate  Introduction

Calcium lignosulfonate is a brown-yellow powdery substance. As a natural anionic surfactant, it is produced via advanced processing technology using sulfuric acid pulping waste liquid as raw material. It exhibits strong dispersibility, adhesiveness, and chelating properties. Xinrui-Te Calcium lignosulfonate is widely used in concrete water reduction, mineral powder briquetting, ceramics and refractory materials, feed and fertiliser, water treatment and other industries.

Calcium Lignosulfonate

Calcium Lignosulfonate Application Fields

◆ Concrete Industry

      It is used as a water reducer to improve construction workability and 

       reduce water consumption.

◆ Smelting Industry

     Used as a slag binder. It can be mixed with mineral powder to make dense  

     briquettes.

◆ Feed Additives

      Improves palatability of livestock and poultry feed, strengthens pellet hardness, reduces powder loss and lowers breeding costs.

◆  Refractory Materials

        Acts as dispersant and adhesive in refractory brick production. It optimizes product performance, reduces moisture content, 

         increases strength and prevents cracking.

◆ Ceramics

       Reduces carbon content, improves green body strength and stabilises the fluidity of clay slurry.

◆ Metal Refining

       Used as an additive for naphthol electrolysis. It promotes dense metal precipitation, upgrades product quality, and lowers cell 

        voltage and energy consumption.

◆ Sand Mould Casting

       Serves as a dry mold adhesive with strong bonding strength and excellent mold collapsibility.

Construction Concrete Application Cases

1.Residential buildings and mixing stations

    Add 0.25%~0.3% calcium lignosulfonate into concrete for residential buildings and mixing stations. It reduces water use, improves 

    concrete fluidity and avoids segregation. It saves 8%~12% cement, increases later strength and prevents cracks.

2.Bridge and road projects

    Calcium lignosulfonate used as retarding water reducer for bridge and road projects. It prevents early setting and pump blockage in       high-temperature summer construction, keeps road surface smooth and prolongs service life.

Calcium Lignosulfonate  Packing, Storage & Transportation

◆Packing

     25 kg PP woven bags lined with plastic film.

◆ Storage

      Store in a dry, ventilated area, protected from rain and moisture. If caking occurs, crush the lumps; the product can 

      still be dissolved into a solution with equivalent performance.

◆Transportation

      Avoid exposure to water and direct sunlight during transit.
