主 题：High voltage electric field three-layer particleboard physical property mechanical property
摘 要：In this study,the effects of three different particle sizes of wood wastes(A=–8+12 mesh;B=–12+20 mesh;C=–20+30 mesh)and factory shavings(D)on the properties of particleboard were *** to the test results,three-layer particleboard was *** face layers made with mixture of A,B,and *** core layer made with *** ratio of core layer to face layers is 50:***-layer particleboard were fabricated with 12%urea-formaldehyde(UF)resins and three different high voltage electrostatic field intensities(0 kv,30 kv,60 kv).The internal bond(IB)strength,modulus of rupture(MOR),modulus of elasticity(MOE),thickness swelling(TS),and water absorption(WA)of particleboard were *** density distribution of the three-layer particleboard were examined by vertical density profiles(VDP),and the bonding mechanism and functional groups changes in the particles were analyzed by FTIR *** results showed that HVEF treatment intensity play a remarkable role in properties of *** particleboard with higher electrostatic field intensities treatment has higher MOE,MOR,IB,and *** HVEF treatment(60 kv),the MOR,modulus of MOE,and IB of three-layer particleboard were 23.61 N/mm^(2),2787.09 N/mm^(2),and 0.86 N/mm^(2),*** indicated that the surface activity of wood particles was increased electric field treatment.
