MH-OSB
MINGHUNG
OSB (Oriented Strand Board) is an engineered wood panel made by oriented layering of wood strands, bonded with resin and consolidated under heat and pressure. The strands are aligned cross-directionally in three layers (face layers longitudinally/core layer transversely), providing high strength, rigidity, and dimensional stability. OSB offers advantages in raw material efficiency (compatible with fast-growing species/small-diameter logs) and environmental performance (no formaldehyde emissions), making it a mainstream alternative to plywood.
Production Process
1.Log processing
Debarking → Stranding → Drying (3-5% MC)
2. Gluing and Directional Treatment
Resin Blending → Oriented Forming (Surface: 0°-15°, Core: 45°-90°)
3. Hot pressing molding
Continuous Press: 180-220°C/15-25MPa, Curing 40-90s
4. Post-processing
Cooling → Trimming → Sanding (Thickness tol. ±0.1mm)
1.working principle
Continuous presses operate via a steel belt circulation system
1. Forming Station: Oriented strands form a continuous mat;
2. Pre-press Zone: Initial compaction to remove air;
3. Hot Press Zone: Mat passes through heated rollers (180–220°C, 3–5 MPa) under steel belts for resin curing;
4. Cooling Zone: Gradual pressure/temperature reduction to relieve internal stress;
5. Cutting System: Sawing the continuous strip to length.
> Advantages: High output (speeds up to 1,200 mm/s), thickness accuracy (±0.1 mm), 15–20% lower energy consumption vs. batch presses.
2.Core Structure and Composition
Hot press plate system: Composed of multiple heating plates, the interior is heated by heat transfer oil or steam to provide uniform temperature.
Steel belt system: Two circulating steel belts (upper and lower) hold the slabs and run continuously to ensure uniform pressure transmission.
Hydraulic system: Pressure is applied through hydraulic cylinders, and the pressing force in different areas can be adjusted in sections.
Control system: PLC or computer control, real-time monitoring of parameters such as temperature, pressure and speed.
Auxiliary equipment: includes paving machines, pre-pressing machines, cooling sections, sawing systems, etc.
3. Technical advantages
Continuous production: Compared with intermittent presses (such as multi-layer hot presses), production efficiency is greatly improved.
Stable quality: pressure and temperature are evenly distributed, the density of the board is highly consistent, the internal stress is small, and it is not easy to deform.
Energy saving and environmental protection: high thermal energy utilization rate, sufficient curing of adhesives, and reduced formaldehyde release.
Flexibility: The pressure curve can be adjusted to adapt to the production of boards of different thicknesses and densities.
Feature | Technical Solution |
Heat Penetration | Extended press length (60m+), longer dwell time (120–180s for thick boards) |
Zoned Temp Control | Independent heating zones prevent surface scorching/incomplete core curing |
Enhanced Pressure | Hydraulic cylinders ≥30,000 kN, stepped pressure profile (higher pressure in core) |
Belt Stiffness | Thickened steel belts (≥2.5mm) + rigid support rollers resist rebound force |
Thickness Monitoring | Multi-channel γ-ray gauges with real-time pressure adjustment (±0.2mm) |
Cooling Strategy | Gradual cooling (80°C→40°C) to prevent delamination |
Thickness Definition: Industry standard defines ≥38 mm as "Ultra-Thick OSB";
Standard Thicknesses:
Construction: 38 mm, 45 mm, 57 mm
Industrial: 60 mm, 75 mm, 100 mm (max. 150 mm)
Density Control: Core density reduced to 650–700 kg/m³ for weight/strength balance, face layers at 750–800 kg/m³.
Application | Functional Requirement | Performance Edge |
Heavy Timber Frame | Beams, columns, trusses, wall studs | Bending strength ≥35 MPa, replaces concrete |
Logistics | Pallet rack decking, container floors (100mm+) | Concentrated load ≥10 t/m², impact-resistant |
Wind Power | Wind turbine blade mold substrates (≥75mm) | Dimensional stability (swelling ≤0.3%) |
Noise Barriers | Highway soundwall cores (45–60mm) | Optimized damping (NRC ≥0.75) |
Specialty Packaging | Military/precision equipment crates (waterproof OSB) | Wet strength retention ≥80% (2h boil test) |
