The influence technological factors of plywood production on glue bond strength
The influence of modifier “pectolite” on the duration of hardening on the glue and strength of glue bond were investigated. “Pectolite” using as a modifier of the phenol-formaldehyde resin give the possibility to shorten the duration of veneer gluing process. Carried out experimental investigation of pine veneer gluing gave the schedule of process. It is possible to increase the efficiency of plywood production by the reduction of expenditure of glue, shortening of gluing process and increasing of glue bond strength.
