The Effects of Some Production Variables on Physical and Mechanical Properties of Particleboard Made of Alnus subcordata by UF and MUF resin

An experiment was conducted to study polymerization conditions and important production factors, the amount of resin and press temperature, on physical and mechanical properties of produced boards by urea formaldehyde (UF) and melamine urea formaldehyde (MUF) were compared. Purify UF resin (control...
