摘要: Urea-formaldehyde (UF) resin (F/U: 1.25), melamine-urea-formaldehyde (MUF) (F/(U+M): 1.05), and three kinds of wood species including poplar (Populus davidiana Dode), beech (Fagus engleriana Seem.), eucalyptus (Eucalyptus robusta Smith) were used to produce plywood. The effects sealing treatment on the formaldehyde emissions studied. anatomical characteristics different measured. results showed that: (1) emission plywood treated by surface was higher than without treatment; (2) nine-ply bonded UF decreased 74.4% 1.98 mg/L after edge (3) compared with plywood, five-ply MUF lowest obtained, at 0.19 mg/L; (4) from changed slightly in spite layers. contact angle spreading-penetration coefficient, K, analyses that cell arrangement dense. Scanning electron micrographs indicated pore sizes samples smallest contrast beech.
