| Abstract | Formaldehyde is a poisonous gas for human health but urea formaldehyde (UF) resins composes more than 90% of resins used in manufacturing of particleboard in the world and particleboard is used in houses largely. In this research, homogenous particleboard with 0.7 gr⁄cm3 manufactured by poplar chips (Populus alba) and urea formaldehyde resin. Variables included of hardener type and particles size, and other conditions were constant. Hardener used were Ammonium Chloride, Ammonium Sulfate and Magnesium Chloride, and amount of hardener used was 2%. Particles prepared by a hammer chipper devided to two groups, small and large chips. After particleboard manufacturing and conditioning, their formaldehyde emission was determined. Formaldehyde emission was measured by WKI method, using acetyl acetone and photometric method (revised standard EN 120). According the results, formaldehyde emission of particleboards made of Ammonium Chloride was less than particleboards made of Magnesium Chloride significantly, but formaldehyde emission of particleboards made of Ammonium Sulfate had no difference with formaldehyde emission of particleboards made of Ammonium Chloride. Particles size had no effect on formaldehyde emission of boards. |
