Applications
Lignosulphonates could work as a binder of powder and granular materials: for iron ore powder, lead and zinc powder, pulverized coal, coke Toner pressure on the ball; extrusion of cast iron, cast steel sand repression; mud-brick wall and floor tiles molding; mineral aggregate into a ball and provides high strength, good stability, lubrication and mold good results.
It is reduce the viscosity of mineral slurries is used to advantage in oil drilling mud, where it replaced tannic acids from quebracho (a tropical tree).
It used as a filler and binder in ceramic tiles, resins to fiber boards, casting sand and in fodder pellets.
Lignosulfonate is used as a dispersant in products like fodder, disperse pesticides, dyes,carbon black, and other insoluble solids and liquids into water.
It is work as plasticizer in making concrete n making concrete to maintain the ability of concrete flow with less water.Also used during the production of cement, where they act as grinding aids in the cement mill and as a rawmix slurry deflocculant (that reduces the viscosity of the slurry).
Packing
It is packaged in 44-lb (20 -kg) and 55-lb (25 kg) HDPE Bag with Liner. sacks.
