Ⅰ.Pine Wood
Pine Wood Properties
1. Fiber Structure:
Tracheids length 1.8-3.2mm (hardwood 0.7-1.3mm), aspect ratio >45
S2-layer microfibril angle 12-18° (hardwood 20-30°) enhances dimensional stability
2. Chemical Composition:
Cellulose 42±3% (optimal bonding range)
Natural resin acids 8-12% (ISO 846 Class B self-preservation)
Global Supply Bases (>100 million tons/year)
Boreal Zone: Siberian Russia (35%), British Columbia Canada (21%)
Subtropical Zone: Paraná Brazil (radiata pine 18-yr rotation), Guangxi China (masson pine)
Emerging Region: Biobío Chile (22m³/ha/year growth)
Ⅱ.Advantages for MDF Production
1. Processing Economy:
40% lower chipping energy (0.18kWh/kg vs hardwood 0.30kWh/kg)
92% fiber yield in refining (eucalyptus 85%)
2. Product Enhancement:
22% higher MOR at same density
Natural 30% formaldehyde reduction (resin acid neutralization)
3. Sustainability:
FSC-certified pine forests: 230 million ha (hardwood 80 million ha)
Ⅲ.MDF Production Process
Stage 1: Raw Material Prep
Debarking → Drum chipping (20×25×5mm flakes) → 3-stage washing (removes grit/resin)
Stage 2: Fiberizing
Pre-steaming (0.6MPa saturated steam) → Twin-disc refining (0.1mm gap, 170℃) → Fiber drying (inlet 180℃, outlet 8% MC)
Stage 3: Forming & Pressing
Air-felt forming (density gradient) → Continuous press (42m long, 185-210℃, 350kN/m) → Moisture control (12±0.5%)
Stage 4: Finishing
24h conditioning (22±2℃, 55% RH) → Double-side sanding (P60→P180) → Ultrasonic flaw detection
Ⅳ.Equipment configuration
1. Drum Chipping System
Working Principle: Logs fed hydraulically into rotating drum where flying knives (35m/s) shear wood against bed knives to produce dimensional flakes.
Key Components:
Multi-stage screen: Separates target flakes (20-30mm) from oversize
Metal detector: Magnetic removal of ferrous contaminants
Counter-flow wash tank: 3-stage rinsing for sand/resin removal
2. Thermo-Mechanical Refining System
Working Principle: Steam-softened chips (0.6-0.8MPa) are fiberized between rotating discs (1500rpm) with intermeshing refiner bars.
Key Components:
Screw feeder: Creates plug seal to prevent steam leakage
Dual-disc refining zone: Adjustable gap (0.05-0.3mm) controls fiber quality
Blow valve: Steam explosion disperses fiber bundles
3. Fiber Drying System
Working Principle: Wet fibers suspended in hot air stream (inlet 180-220℃) undergo convective drying during pneumatic transport.
Key Components:
Cyclone separator: Isolates dry fibers from humid air
Moisture feedback: Infrared sensors regulate inlet temperature
Explosion suppression: Nitrogen injection triggered by spark detectors
4. Air-Forming System
Working Principle: Compressed air propels fibers through oscillating nozzles to build layered mat (fine surface/core coarse) on moving screen.
Key Components:
Classifying screen: Segregates fine surface fibers (＜0.2mm)
Vacuum forming box: Stabilizes mat with negative pressure
Pre-press rolls: Compacts mat to 30% target thickness
5. Continuous Hot Press
Working Principle: Mat cures under heat (180-210℃) and pressure (3-4MPa) while conveyed through steel belt press with staged compression.
Key Components:
Zoned pressure control: 30+ hydraulic cylinders adjust sectional force
Belt cooling section: Water-cooled zones prevent warping
Thickness scanner: Gamma-ray real-time monitoring with closed-loop control
6. Finishing Line
Working Principle: Pressed boards are conditioned for moisture equilibrium, then calibrated and trimmed to final dimensions.
Key Components:
Flip cooler: Forced-air cooling below 50℃
Multi-head sander: Coarse grinding (P60) → finish polishing (P180)
Cross-cutting saw: Servo-positioned cutting (±0.15mm tolerance)
Ⅴ.Annual production capacity of 300000m³
Global Tier Standards:
Small: <100,000m³/year (regional)
Medium: 100-250,000m³ (national)
Large: 250-500,000m³ (export-oriented) ← This project
Mega: >500,000m³ (global integration)
Economic Transport Radius:
Trucking: 800km (freight ≤$35/m³)
Railway: 2,000km (China-Europe rail 18 days)
Shipping: Global ports (wood chip shipping $18-25/t)
Key Markets:
1. Europe: Germany/Poland (500km radius)
2. Asia: Vietnam/Thailand (Beibu Gulf ports)
3. Americas: Mexico (US tariff avoidance)
