Ⅰ.Particle Board Introduction

1. Definition & Applications  

Particle board is a panel product manufactured from wood fragments (shavings, sawdust, wood chips) through drying, adhesive application (urea-formaldehyde resin or MDI), mat forming, and high-temperature/high-pressure pressing.  

Primary Applications: Furniture manufacturing (cabinets, countertops), building interiors (flooring substrates, partitions), packaging materials.

2. Production Process

3. Key Performance Metrics  

Density: 550-750 kg/m³ (Medium-Density Particle Board)  

Emission Class: E0/E1 (Formaldehyde emission ≤0.5mg/L)  

Physical Properties: MOR ≥15MPa, IB ≥0.4MPa (GB/T 4897 Standard)  

1. Technical Principle  

A continuously moving steel belt transports the formed mat through high temperature (180-220°C) and pressure (2.5-4.5 MPa), enabling adhesive curing and panel consolidation in a single pass.  

2. Key Advantages  

- 30%+ Higher Efficiency: No open/close cycles, 24/7 operation  

- Superior Thickness Uniformity: Tolerance ±0.2mm  

- Lower Energy Consumption: 15-20% energy savings via heat recovery  

- Flexibility: Produces panels from 1.5mm to 40mm thickness  

3. Key Components  

System Module	Function	Technical Parameters
Steel Belt Drive	Continuous mat conveyance	Belt thickness: 1.5-2mm,      Width: 2.8m
Segmented Hydraulic Pressing	8-12 independent pressure zones	Pressure gradient: Infeed > Center > Outfeed
Thermal Oil System	Provides stable heat	Temperature control: ±1°C
Thickness Control	Laser scanning + real-time pressure adjustment	Thickness deviation: ≤0.15mm
Forming System	Creates uniform mat	Air-sifting/mechanical forming

4. Typical Specifications (150,000 m³/year Model)  

Press Length: 35-45 meters  

Working Width: 2.7m (produces 2,440mm wide panels)  

Line Speed: 800-1,500 mm/s (adjustable by thickness)  

Installed Power: ~3,500-4,500 kW  

Heat Source: Thermal oil boiler (15-20 MW thermal capacity)  

2.Production Scale Positioning

Capacity Tier	Annual Output Range	Characteristics
Small-scale Lines	<80,000 m³	Batch presses; local markets
Medium-scale Lines	80,000–200,000 m³	150,000 m³: Core segment
Large-scale Lines	200,000–400,000 m³	Leading players; ample raw material supply required
Mega-scale Lines	>400,000 m³	Global giants

3. Market Competitiveness Analysis  

3.1 Efficiency & Economics  

Lower breakeven point: ~18% reduced unit cost vs. <100,000 m³ lines  

OEE (Overall Equipment Effectiveness): ≥85% (vs. 70–75% for small lines)  

Labor efficiency: 30% fewer workers per 10,000 m³ (≈1.5 workers/10,000 m³)  

3.2 Technical Adaptability  

Continuous press essential: Economically viable only for capacities ≥80,000 m³  

Rapid thickness changeover: 1.5–40mm adjustment in 10 mins (vs. 1 hr for multi-opening presses)  

3.3 Market Coverage Capability  

Metric	150,000 m³ Line Capacity
Daily output	~500 m³ (300 operating days)
Supply capacity for furniture manufacturers	Supports 10–15 mid-sized factories
Economical sales radius	500–800 km (truck transport)
