Uses of Chengli Sodium Lignosulfonate

(1) Sodium Lignosulfonate in Concrete. As a kind of common water reducing admixtures, it can be compounded with high range water reducing admixture (such as PNS). Besides, this product is also used as an ideal pumping agent. As a water reducer, the recommended amount (by weight) of sodium lignosulfonate in concrete cement is about 0.2% to 0.6%. We should determine the optimum amount by experiment. However, the amount of sodium ligninosulfonate must be strictly controlled. If the effect is not obvious, it will affect the early strength of the concrete. When the temperature is lower than 5 °C, it is not suitable for concrete engineering alone.

(2) More Uses. Chengli sodium lignosulfonate is also widely used in textile dyestuff, metallurgic engineering, petroleum industry, pesticides, carbon black, animal feed, and porcelain, etc
