‌Coagulants are water-soluble polymers with low molecular weight and high cationic charge density.

Promote the coagulation of material particles, so that they form a uniformly dispersed colloid or gel state in the liquid chemical additives.

Inorganic coagulants

Mainly includes aluminium salts (such as polymeric aluminium chloride PAC, aluminium sulphate, etc.), iron salts (such as polymeric ferric sulphate, ferric chloride, etc.) and their polymers.

Mainly through the compression of the double layer, adsorption and electric neutralisation, adsorption and bridging, sediment netting and other mechanisms, so that the water fine suspended particles and colloidal ions destabilisation, aggregation, flocculation, coagulation, precipitation, to achieve purification and treatment effects.

Application fields

1.Water treatment: Coagulants are widely used in the field of water treatment to remove suspended solids, colloids, organic matter, heavy metals and other pollutants in water. Through coagulation and precipitation, it can improve the clarity and transparency of water.

2.Construction field: In the process of concrete preparation, coagulant can improve the fluidity of concrete and construction efficiency. At the same time, it can also reduce the resistance of cement hydration and increase the compactness and compressive strength of concrete.

3.Pulp industry: Coagulants can promote the dispersion and suspension of fibres, making the paper preparation process smoother. At the same time, it can also improve the strength and uniformity of paper.

4.Ceramics and ore processing: In ceramics and ore processing, coagulant can promote the aggregation and crystallisation of particles, and improve the strength and hardness of materials.
