dc.description.abstractINTRODUCTION: PARTICLE BOARD PRODUCTION IS BASED ON THE USE OF SAWMILL AND REMANUFACTURING RESIDUES; HOWEVER, THE AVAILABILITY OF THIS RAW MATERIAL HAS DECREASED SIGNIFICANTLY DUE TO ITS USE AS BIOMASS FOR FIREWOOD FUEL. OBJECTIVE: TO EVALUATE THE EFFECT OF THE REPLACEMENT LEVEL OF MAIZE (ZEA MAYS L.) AND PINUS RADIATA D. DON RESIDUES ON PHYSICAL AND MECHANICAL BOARD PROPERTIES. MATERIALS AND METHODS: MAIZE AND P. RADIATA RESIDUE PROPORTIONS BETWEEN 0 % (CONTROL) AND 30 % MAIZE WERE EVALUATED. UREA-FORMALDEHYDE ADHESIVE WAS USED IN PROPORTIONS OF 7.5 % AND 9.5 % FOR FINE AND THICK PARTICLES, RESPECTIVELY; PRESSING WAS BASED ON INDUSTRIAL PARAMETERS WITH A THICKNESS OF 10 MM AND 0.77 G?CM-3 DENSITY. PHYSICAL AND MECHANICAL PROPERTIES WERE DETERMINED ACCORDING TO PARTICLE BOARD STANDARDS. RESULTS: THICKNESS, DENSITY, MOISTURE, MODULUS OF ELASTICITY AND MODULUS OF RUPTURE WERE SIMILAR AMONG MAIZE RESIDUE PROPORTIONS AND MET THE INDUSTRIAL REQUIREMENT. AT 2 AND 24 H, ABSORPTION AND SWELLING MET THE INDUSTRIAL AND REGULATORY REQUIREMENT, EXCEPT FOR SWELLING AT 2 H WHEN 30 % MAIZE RESIDUES WAS USED. THE INTERNAL BOND (IB) MET THE INDUSTRIAL REQUIREMENT WITH ALL PROPORTIONS, BUT FROM 20 % ONWARDS THERE WAS A SIGNIFICANT DECREASE (P < 0.05). CONCLUSIONS: MAIZE RESIDUE PROPORTIONS BETWEEN 0 AND 10 % HAD SIMILAR PERFORMANCE. A PROPORTION OF UP TO 20 % MAIZE PROVIDED REGULATORY AND INDUSTRIAL COMPLIANCE, SO IT HAS POTENTIAL FOR THE PARTICLE BOARD INDUSTRY.
