Reducing Particleboard Pressing Time: Exploratory Study.
Abstract
Minimum presstimes are studied for a suitable combination of time and temperature to cure the binder and dispel sufficient moisture to avoid steam blisters. 1/2-inch-thick board produced in as little as 1 minute presstime by proper selection of variables is reported. Variables most effective in reducing presstimes were higher press temperatures, fast press closing, and nonuniform mat moisture contents. Data were obtained from strength tests on more than 90 boards with five replicate tests per board.
