Factors Affecting Particleboard Pressing Time: Interaction with Catalyst Systems.
Abstract
In laboratory manufacture of particleboards, use of catalyst, high press temperature, fast closing, and nonuniform mat moisture content produced adequate 1/2-inch-thick, urea-bonded panels in 1 minute and phenolic-bonded panels in 2 minutes presstime. The use of a catalyst allows the reduction of presstime by approximately 1 minute for urea-formaldehyde resin systems, but no reduction was obtained with catalyzed phenol-formaldehyde systems.
