Application
1.Industrial Binder
Lignosulfonate working as coke powder binder
1.Mixing:geenerally 5% W/W to mix the binder and coke powder,even if the coke contends high of moisture .
2.Moulding into balls: make powder into balls by some water according to the moisture of coke powder .After moulding the ball could make shape even falling from 2m high,the strength is around 100kg/ball,without any chemcial additives.The tempreture can reach 1000 degree centrigrade.
2.Animal Feed additives
Despite the expanded awareness of sodium lignosulfonate potential in horticulture, there is still very little understanding of the potential in animal husbandry. In China, who successfully introduced acupuncture and their traditional herbal medicines to the West, have been utilising sodium lignosulfonate in the animal feed industry for over 25 years and they are passionate about the many benefits.
3.Construction admixture
(1).Lignosulfonate superplasticizer dosage of cement content 0.20-0.30%, commonly used dosage is 0.25% water reduction of up to 9-11%. In the appropriate dosage when compared with the reference concrete strength increased by 15-20% 3 days, 7 days strength increased 20-30%, 28 days by 15-20%, long-term strength also increased.
(2).Without changing the water in the case of concrete( suggested ratio 0.65)1to increase the flow of concrete, improved work-ability.
3.In keeping concrete slump, the same intensity and the reference concrete, cement can save 8-10%, the use of one ton of lignosulfonate superplasticizer powder, can save 30-40 tons of cement.
