A Comparative Study of Free Formaldehyde Control Technology in Wood-Based Panels

Adopted the treatment methods of ultrasonic dispersion on nano-TiO2/Al2O3, of sustained-releasing ClO2 and of post-heating way. The results show that the reduction rate of formaldehyde emission treated by nano-TiO2/Al2O3 is 22.2%, the average reduction rate of particleboard free formaldehyde in nine days is 64.7%, and the post-heating- treatment can reduce the plywood formaldehyde by 34.5%.

Reduction Effect

Abstract The rainfall runoff reduction effect on green roofs was analyzed and tested by comparative rainfall runoff monitoring on impermeable roofs (sloping, plane). The evaluation index of rainfall runoff interception benefit (relative runoff reduction rate, rainfall control rate) on green roofs was studied. The results show that compared with sloping and level roofs, the change range of green roof runoff reduction rate relative to level and sloping roofs is 20.0–98.3% and 3.8–92.3%, and the mean value is 48.4% and 34.3% respectively. It is obvious that the green roof has better rainfall runoff reduction effect. It can be seen from the single rainfall control effect that the variation range of green roof rainfall runoff control rate is 36.0% to 99.0%, and the total rainfall control rate is 57.6%, which reflects that the green roof has the better rainfall control effect. Through comparative study, it can be concluded that the rainfall runoff control rate is more suitable for the design index of green roofs.
