Optimization of corn-stalk skin flake-wood shaving composite technology

         

摘要

We focused on the optimization of corn-stalk skin flake-wood shaving composite technology. We studied the effects of material-mixture ratio, glue content, hotpressing temperature, and hot-pressing time on the appearance, physical, and mechanical properties of the composite by the orthogonal experiment method. Our findings yielded highly significant results in all three cases: the effects of the material-mixture ratio on 2 h of thickness swelling(2h TS)and the modulus of rupture(MOR); the effects of glue content on 2h TS, internal bond strength, and modulus of elasticity(MOE); and the effects of hot-pressing temperature on MOR and MOE. Product optimization is achieved when the ratio of corn stalk skin flake to wood shaving is 3:7, the glue content is 12 %, the hot-pressing temperature is 150 °C, and the hot-pressing time is 4.5 min.
