| Part V: Auxiliary and Environmental Protection Systems |
9. Conveying System
Roller Conveyors, Belt Conveyors, Lifters, and Transfer CartsThroughout the entire line, connecting individual machines into an automated production line.
10. Central Control System
PLC + Industrial Computer: The "brain" of the production line. Integrates control of all equipment, enabling digital management and monitoring of the entire process from veneer drying temperature, glue spread rate, hot pressing parameters (temperature, pressure, time curve) to sanding amount. This is essential for producing stable, traceable, high-quality E0 grade products.
11. Environmental Protection System
Dust Removal System: Dust hoods are installed at dust generation points (peeling, cutting, sanding) and connected via ducts to a Central Dust Collector to collect wood dust and purify workshop air.
Exhaust Gas Treatment System: Collects and treats volatile organic compounds (VOCs) emitted from dryers and hot presses to achieve clean emissions.
Production Process
The production of E0 grade plywood is a precise and strictly controlled process. Its core lies in using eco-friendly adhesives and ensuring the final formaldehyde emission reaches an extremely low level (≤0.5mg/L) through process control. Here are the detailed production steps:
1. Raw Material Preparation and Processing
Log Selection: Fast-growing woods like poplar, eucalyptus, and pine are primarily used. Logs should have uniform diameter and minimal defects.
Debarking and Bucking: A debarker removes the bark, and a cross-cut saw cuts the logs into blocks of specific lengths.
Veneer Peeling: The log block rotates on a peeling lathe and is cut by a sharp blade into continuous veneer sheets. Veneer thickness is typically 1.0-3.5mm, and uniformity is critical.
Veneer Drying: Wet veneer sheets pass through a veneer dryer (usually roller or mesh belt type), where hot air precisely reduces their moisture content from over 60% to 8%-12%. Precise drying is fundamental for ensuring bonding quality and reducing energy consumption.
Veneer Sorting and Patching: Dried veneer is sorted by grade (face, back, core). High-quality face veneer is processed by a CNC patching machine, which automatically identifies and removes defects like knots and wormholes, replacing them with sound wood patches, greatly improving material utilization.
2. Glue Application and Layup (Core Environmental Step)
Mixing Eco-Friendly Adhesive: This is the core of achieving the E0 standard. Formaldehyde-free or low-formaldehyde adhesives are used, such as:
MDI (Diphenylmethane diisocyanate): Completely formaldehyde-free, excellent bonding performance, but higher cost and requires high equipment sealing.
Soy-Based Protein Glue: Biomass adhesive, no formaldehyde added, good environmental performance.
E0 Grade Urea-Formaldehyde (UF) Resin: The free formaldehyde content is significantly reduced by adjusting the molar ratio and adding formaldehyde scavengers (e.g., melamine, starch).
Quantitative Glue Application: A double-sided four-roller glue spreader is used to apply adhesive evenly and quantitatively to both sides of the veneer. The glue spread rate must be precisely controlled; too little affects bond strength, too much increases cost and may introduce more volatiles.
Layup: Glued veneers are assembled into a mat according to the designed number of layers (odd number) and grain direction (adjacent layers perpendicular). Automated layup lines use robots for high efficiency and stable quality.
3. Pre-Pressing and Hot Pressing
Pre-Pressing: The mat is sent to a cold pre-press, where a pressure of 0.5-1.0 MPa is applied at room temperature for 10-30 minutes. This causes initial bonding of the veneers, providing sufficient green strength for transportation and loading into the hot press, preventing mat collapse.
Hot Pressing: This is the key process for adhesive curing and forming. The mat is fed into a hot press (multi-opening or continuous flat press), where it is subjected to specific temperature (105-120°C), pressure (5-15 MPa), and time (adjusted according to thickness). The adhesive undergoes a chemical reaction and cures, firmly bonding the veneers into a whole. Precise control of the hot pressing process directly determines the product's bond strength, formaldehyde emission rate, and final thickness.
4. Post-Processing and Finishing
Cooling and Curing: The plates that have just come out of the hot press machine have a very high temperature and significant internal stress. It is cooled by a cooler turner with forced air and then stacked for curing for 24-72 hours. This process allows complete adhesive curing, internal stress equilibration, and moisture content stabilization, which is crucial for controlling deformation and stabilizing formaldehyde emissions.
Sanding: The cured boards are sanded on both sides by a calibrating sander (usually with three or four heads) to eliminate thickness deviations and pre-press marks, obtaining a smooth, flat surface and precise thickness.
Trimming and Grading: The rough-edged boards are cut to standard dimensions by a panel saw, then graded based on appearance, thickness, and environmental grade, before being packaged and stored.
