Abstract

Background and objective: In this study, for the useful consumption of residue materials that have no specific consumption and are waste, it was started making the particleboard from the mixing of Corn stalk, Wheat straw and industrial wood particles. Then, the physical and mechanical properties of the boards were measured. Because of the consumption of these raw materials that have a low price (if possible), it can reduce the cost of production of this type of product. Materials and methods: For this purpose, Corn stalk, Wheat straw and industrial wood particles at levels of 0: 100, 25: 75 and 50: 50, Press temperature of 160 and 180° C and 12 percent of urea formaldehyde resin based on the dry weight of the particles were used for the production of particleboards. The physical and mechanical properties of the boards including Thickness swelling within 2 and 24-hour immersion in water, Bending strength, Modulus of elasticity and internal bonding were measured and all the data were statistically analyzed. Results: The results of this research showed that the increase in Corn stalk and Wheat straw in the mixture showed in increased Thickness swelling within 2 and 24-hour immersion in water. It means increasing the amount of Corn stalks and Wheat straw had a negative effect on the Thickness swelling of the boards. The amount of Bending strength, Modulus of elasticity and internal bonding decreased with the increase of Corn stalk and Wheat straw particles in the boards and there was a significant difference between different levels of Wheat straw and Corn stalks. Also the Press temperature increase from 160 to 180 ° C had a significant effect on all the properties of the boards and improved the physical and mechanical properties of the boards. Increasing the temperature of the press also had a significant effect on all the properties of the boards and improved the properties. Conclusion: According to the results of this research, using Corn stalk, Wheat straw and industrial wood particles, increased significantly the dimensional stability of the boards. Bending strength, Modulus of elasticity and internal bonding in control samples showed the highest values. But compared to the properties of the boards produced by EN standard, using 25% Corn stalk and Wheat straw, 12% urea formaldehyde resin and Press temperature of 160 ° C, can be produced particleboards with favorable properties. This is a positive result for the use of mixing this kind of agricultural wastes including Corn stalk and Wheat straw, following that the prevention of environmental pollution caused by the burning of these compounds.
