Continuous Press Machine Press Systems For Biodegradable Plates

Fully Automatic 300~1500 Cbm Per Day Particle Board Continuous Press Production Line

Description

As the hot-press represents the key operation in any wood-based composite manufacture, studies have been carried out to understand and evaluate its influence on board properties. During such an operation, mats of wood flakes mixed with adhesive are consolidated under heat and pressure, creating close contact and forming bonds between the wood constituents (Dai and Wang 2004). To increase production capacity and decrease product cost, the industry uses extreme conditions for pressing (in cycle presses), such high temperatures (up to 200 °C) and short pressing cycles. Long press closure times will cause a reduced bond between surface particles and surface peel-off in OSB . The increase of pressing time from 3 to 7 min improved the OSB properties at 0.4 MPa pressure, in a single opening press .

The 300~1500m³/day particle board production line uses raw material through chips preparation, flakes preparation, dring and sitfting, glue dosing system, forming and hot pressing, cooling &trimming and sanding section to make particle board / chipboard. The final size can be 4 x 8, 6 x 8, 6 x 9, 4 x 12, 6 x 12, 6 x 18. The particle board has homogeneous structure, smooth surface, good machining specification and manufacture performance. It is the ideal substitute of nature wood.
