| Abstract | Technology of low-temperature veneer gluing in the manufacture of phenol-formaldehyde (PF) plywood has been investigated. The research on modification of PF resins by various chemical compounds (resorcinol, melamine, urea, para-formaldehyde, hydrogen peroxide, dichromate ammonium, potassium and sodium) has been done. Such modification gives a possibility to make plywood at reduced pressing temperature of 100 °C in comparison with the usual temperatures of 120-130 °C. The low-temperature pressing results in a significant energy saving process in comparison with high-temperature pressing, without any worsening of mechanical properties of plywood. |
