For increase of binding ability liquid technical lignin sulfonate the Perm pulp and paper mill, modification is carried out them. It is established that the greatest binding ability when pressing metalbriquettes is reached, when using karbamidoformaldegidny pitch with an expense of 5 mass percent to lignin sulfonate to the technical.
