Sodium Lignosulphonate By Krishna Chemtech

Building materials production: Due to its astringent, sticking and surface active properties lignosulfonates are used for producing plates: wood chips, wood-fiber and mineral-cotton. As in this production rather deficit, expensive, toxic, phenolformaldehyde, carbamide-phenolformaldehyde loams are used, mixture of modified lignosulfonate (20-30%) and loam lets to get combined binder.Thus toxication of plates, machined with additives on the base of lignosulfonates, reduces up to 50%. If use 40 kg/m2 of lignosulfonate while producing of mineral-cotton plates, we can succeed in fall-off of flow volume of toxic phenolic alcohols and therefore significal reducing of noxious emissions to the atmosphere. In addition wares are more firm and water-proof.
