Phenol-formaldehyde resins modified with lignosulphonates for the manufacture of plywood and fibreboards

, : Phenol-formaldehyde resins modified with lignosulphonates for the manufacture of plywood and fibreboards. Derevoobrabatyvayushchaya Promyshlennost' (10): 3-5

In trials at several plywood and fibreboard factories in European Russia, various grades of technical lignosulphonates were substituted for 10-15% of the phenol in the resins. The quality of the modified resins and of the resulting boards conformed to the Soviet standards. Neutralized Na-type lignosulphonate gave the best adhesive properties, with the possibility of 25% substitution.
