EFFECTS OF SOME TECHNOLOGICAL FACTORS DISPERSION ZINC OXIDE (ZnO) NANO TO THE CHARACTERISTICS OF WOOD

Abstract

Results of studies on the effect of concentration and dispersion time of ZnO nano on the properties of cashew wood. ZnO nano particles were dispersed in solutions at concentrations of 1; 2; 3 g/l for 4 hours, 8 hours, and 12 hours using an ika and stirred at 2000 rpm for 2 hours. this dispersion solution is used to soak cashew wood samples. the research results showed that the swelling and moisture balance of the treated wood decreased sharply compared to the control sample to improve the dimensional stability of the wood sample. the swelling on the tangention decreased from 9.2% to 6.39% compared with the control sample. the hardness on the tangention increased from 205,45-258,45kG, To improve the quality of cashew wood and bring economic efficiency, it is appropriate to use ZnO nano at a concentration of 2,302g/l and a 11hour of dispersion.
