At the present time one of the problems of the plywood production is to decrease
the toxicity of plywood to a level corresponding to the requirements of European
standard (EN 717-2).
The chemical composition of the modifier pectol is considered. Schemes of
interaction of the resin acids which are a part pectol, with phenol and formaldehyde
are offered. Modifier influence pectol on duration of process of pasting of an interline
interval and durability of glue connection is experimentally investigated. It is
established that application pectol as the modifier of phenol formaldehyde SFZh-3013
pitch allows to accelerate process of pasting of an interline interval, increases
durability of glue connection and reduces the content of free formaldehyde in finished
goods.
