I. Particleboard
1.Definition: An engineered wood panel manufactured by compressing wood particles or non-wood plant fibers (e.g., branches, sawdust, recycled wood) with synthetic resin adhesives (typically urea-formaldehyde UF or melamine-modified UF resin) under high temperature and pressure.
2.Key Characteristics:
Low cost, raw material utilization >90%
Uniform density (typically 550-750 kg/m³)
Smooth surface suitable for veneering/painting
High transverse bending strength but weak water resistance (improved with additives)
3. Particleboard Classification and Specifications
3.1 Density Grading (EN 312 Standard)
Type | Density Range (kg/m³) | Application Scenarios |
Lightweight | <550 | Non-load-bearing partitions, decorative backings |
Standard | 550-750 | Furniture structural panels, flooring substrates |
High-Density (HDF) | >750 | Laminate flooring, door cores |
3.2 Functional Classification
Type | Key Properties | Standard |
Standard | For indoor dry environments | GB/T 4897.1 |
Moisture-Resistant | Wax/waterproof additives (≤85% RH) | GB/T 4897.2 |
Fire-Retardant | Al(OH)₃/P-N flame retardants | GB 8624 Class B1 |
Low-Formaldehyde | Formaldehyde emission ≤0.5mg/L (E0) | GB 18580 |
3. 3 Layered Structure
Structure Type | Cross-Section Feature | Performance Advantage |
Single-Layer | Homogeneous particle distribution | Lowest cost |
Three-Layer | Fine surface + coarse core particles | Superior surface quality |
Graduated | Particle size gradient from surface to core | High bending strength |
3.4 Specifications
Parameter | Typical Range |
Thickness | 3mm-40mm (1mm increments) |
Panel Dimensions | 1220×2440mm, 1830×3660mm, etc. |
Emission Class | E1 (≤0.124mg/m³), E0 (≤0.05mg/m³) |
II. Intelligent Temperature Control System
1. System Components
Component | Function Description |
Temperature Sensors | Thermocouples/IR sensors monitor surface & core temp |
Heat Medium Unit | Thermal oil/steam for zoned control (±1℃) |
PLC Controller | Processes data and outputs commands |
Actuators | Control valves regulate heat medium flow |
2. Working Principle
Temp Sensor Monitoring --> Data → PLC --> PID Calculates Deviation --> Output Adjustment Signal --> Actuator Modulates Valve --> Dynamic Temp Balance
Ⅲ. PID Regulation: Principles and Implementation
1. Physical Zone Design
The press is divided along its length into 16 independent temperature control zones (typically 1-3 meters per zone), each equipped with:
Independent heating unit (thermal oil/steam circulation pipelines).
High-sensitivity temperature sensors (real-time monitoring of surface/core layer temperature).
Dynamic pressure compensation device (ensures synergy between pressure and temperature in each zone).
Zoning Logic:
Inlet Zone (Zones 1-4): High temperature (200-230°C) for rapid heating to activate resin flow.
Middle Zone (Zones 5-12): Constant temperature (180-200°C) for thorough core-layer cross-linking.
Outlet Zone (Zones 13-16): Gradient cooling (160-180°C) to reduce warping caused by internal stress.
2. Control Logic in Hot Presses
Control Action | Mechanism | Practical Example |
P Action | +20% heat flow if temp drops 5°C | Rapidly suppresses fluctuations |
I Action | Compensates for moisture-induced heat loss | Prevents under-curing from sustained low temp |
D Action | Preemptively boosts heat before predicted drop | Stabilizes temp during feed acceleration |
3. Technical Advantages
3× faster response vs. ON/OFF control
Overshoot < ±1.5°C (vs. ±5°C conventional)
Improved curing uniformity → IB strength variation ≤5%
Ⅳ. Industry Value
Quality Enhancement: Thickness tolerance reduced from ±0.3mm to ±0.1mm
Energy Savings: 15-20% steam waste reduction via precise control
Flexible Production: Auto-adjusts temperature profiles during thickness changes (e.g., extends dwell time for 18mm boards)
> Technology Trend: Next-gen systems integrate Fuzzy-PID and neural network prediction for real-time curing control (e.g., closed-loop regulation via dielectric constant monitoring).
