Particleboard:
A panel formed by hot pressing wood or non-wood plant particles (flakes, sawdust, etc.) blended with adhesive. It features a homogeneous structure and low cost, widely used as furniture substrate and decorative backing.
Continuous Hot Press:
Utilizes circulating steel belts to carry the mat continuously through a high-temperature, high-pressure zone for curing. Compared to batch-type multi-opening presses, it offers core advantages of high efficiency, low energy consumption, and consistent quality.
Feature | Particleboard Continuous Press | OSB Continuous Press |
Raw Material Form | Random particles (sawdust, small flakes) | Oriented long strands (length ≥50mm) |
Forming Requirement | Uniform forming, no orientation | Multi-layer oriented forming (cross-directional) |
Product Structure | Homogeneous single-layer or graduated | 3/4-layer oriented structure |
Strength Property | Isotropic | Anisotropic (longitudinal > transverse strength) |
1. Physical Parameters
Useful Width: 2.5m – 4.2m (Mainstream: 2.8m/3.6m)
Press Length: 25m – 45m (Shorter for thin boards, longer curing zone needed for thick boards)
Steel Belt Speed:
Thin boards (3-8mm): 800–1200 mm/s
Thick boards (18-40mm): 150–400 mm/s
2. Process Capabilities
Parameter | Typical Range | Remarks |
Thickness Range | 2.5mm – 40mm | <3mm ultra-thin boards require special design |
Working Pressure | 2.5 – 4.0 MPa | High-pressure zone for rapid mat compression |
Heating Temperature | 180°C – 220°C | UF resin: 180-200°C |
Annual Capacity | 200,000 – 400,000 m³ | Based on 15mm board, 3.6m width, 500mm/s speed |
3. Precision & Energy Consumption
Thickness Tolerance: ±0.2mm (can reach ±0.1mm after sanding)
Density Deviation: ≤±3% (key indicator for surface uniformity)
Comprehensive Energy Consumption:
Electricity: 30–50 kWh/m³
Steam: 500–800 kg/m³ (including drying + pressing)
Subsystem | Technical Highlights |
Forming System | Air/mechanical forming ensuring uniform particle distribution (density fluctuation ≤5%) |
Steel Belt Unit | 1.6–2.0mm thickness, chrome-plated anti-stick surface (thinner than OSB presses for high speed) |
Heating System | Thermal oil circulation + zoned temp control (6-8 zones), ΔT ≤±2℃ |
Hydraulic System | 15-30 pressure zones, gradient control from entry high-pressure (3.5MPa) → exit low-pressure (1.0MPa) |
Anti-Stick Tech | Laser-microtextured belt surface + silicone release agent spraying system |
1. Core Functions of PLC in Continuous Presses
Functional Module | Control Target | Technical Highlights |
Steel Belt Sync Drive | Main drive motor + idler rolls | Servo closed-loop control (±0.1mm/s precision) |
Gradient Pressure Ctrl | Hydraulic zones (30-50 zones) | PID pressure regulation (fluctuation ≤±0.05MPa) |
Zoned Temp Management | Heating plate thermal oil circ. | Thermocouple + smart PID (ΔT ≤±1℃) |
Mat Weight Feedback | Online density scanner | Real-time forming motor adjustment (density dev. ≤3%) |
Safety Interlocks | E-stop/belt drift/overload prot. | SIL3 safety circuit response <100ms |
2.Key Component Specifications
CPU: Supports multitasking (1ms cycle), >99.99% availability with redundancy
Communication:
PROFINET IRT (Real-time, jitter <1μs)
OPC UA protocol (MES/ERP integration)
Remote I/O: IP67 rating for high-temp/humidity environments
