Process for producing composite boards by making use of phenol formaldehyde binding agent

摘要

Wood composite boards are produced from a wood fiber treated with a slow curing, low alkalinity phenol formaldehyde (PF) resin. The resin treated wood fiber is consolidated and cured in a press using steam injection. The slow curing nature of the resin prevents pre-cure of the resin. The press using steam injection speeds curing so that boards can be produced in press cycles comparable to the curing of wood fiber treated with other resins in a press with no steam injection.
