Product Description

12mm Daily Output 500m³Waterproof Mixed Wood OSB (1250×2500mm)

China wood based panel machinery

Production Process

1. Log Processing: Debarked mixed hardwood logs cut into 2.5m sections, softened by 100℃ steam

2. Stranding: Disk flakers produce oriented strands (100mm length × 0.6mm thickness)

3. Drying & Screening: Rotary dryer reduces moisture to 3%, vibrating screens filter qualified strands

4. Blending & Gluing: Surface/core strands separately coated with 8-10% phenolic resin (PF)

5. Oriented Layup: Cross-layered 3-ply structure (surface layer longitudinal + core layer transverse), density variation <5%

6. Hot Pressing: Continuous press (200℃, 1500psi) cures for 120 seconds

7. Conditioning & Cutting: Stress-relieved in climate-controlled chamber for 24hrs, sanded and cut to 1250×2500mm

8. Waterproofing: Nano-silane water repellent spray achieves 0.5mm penetration depth

9. QC & Packaging: Density graded by X-ray scanner, packed with moisture-proof film + wooden pallets

OSB Production process_副本

Key Machinery

Ring-type wood chipper

Operating Principle: Logs are radially cut by a high-speed rotating ring cutter (800-1200rpm). Hydraulic pushers feed logs at constant speed, with strand length controlled by feed rate.

Key Components:

Tungsten-carbide-tipped ring cutter (Ø2.5-3m)

Hydraulic constant-speed feed system

Adjustable counter knife bed

Strand screening unit (removes oversized chips)

Chips drying Machine for OSB Production Line

Drum dryer

Operating Principle: Wet strands tumble in an inclined rotating drum (3-5° tilt) under hot air (180-220℃). Moisture is exhausted via rear ducts, with drying process controlled by humidity sensors.

Key Components:

Rotating drum (20-30m long, internal lifters)

Gas/biomass hot air generator

Cyclone dust collector

In-line moisture sensors

Oriented Strand Board Glue Sizing System

Staining System

Operating Principle: Dry strands are coated with atomized resin in a rotating drum. Dual application (pneumatic nozzles + mechanical scattering) ensures uniformity, with glue volume metered by mass flow controllers.

Key Components:

High-speed blending drum (15-20rpm)

Multi-zone pneumatic resin spray towers

Adhesive preheating circulation unit

Gravimetric glue dosage system

Directional paving machine

Operating Principle: Electrostatic fields align glued strands at preset angles (surface layer 0°/core layer 90°) during free-fall. Servo-driven spreading heads traverse laterally for uniform mat formation.

Key Components:

High-voltage electrostatic generator (50-100kV)

Programmable spreading head traversing system

Multi-layer weighing belt scales

Real-time density scanners

Continuous hot press machine

Operating Principle: Mat is compressed between two continuous steel belts with zonal pressure control (1500psi front → 800psi rear). Heated plates (200℃ via thermal oil) cure resin, with belt speed determining thickness.

Key Components:

Multi-zone hydraulic cylinder system (30+ groups)

Thermal oil heated plate assemblies

High-temperature alloy steel belts (1.5-2mm thick)

Laser thickness monitoring sensors

Sanding cutting line

Operating Principle: Boards are thickness-calibrated via dual-face sanding (40→120 grit progression), then cut to length by flying saws with simultaneous edge profiling/chamfering.

Key Components:

Heavy-duty thickness sander (contact roller + pressure bar)

Servo-driven flying saw (100m/min cutting)

CNC 4-edge milling station

Automated stacking robot

MINGHUNG wood based panel production line

Waterproof Mechanism

Triple Protection:

1. Resin Sealing: Phenolic resin forms waterproof mesh (contact angle >110°) during hot pressing

2. Structural Barrier: Cross-layered strands block vertical water penetration

3. Surface Treatment: Nano-silane coating creates lotus effect (water bead roll-off time <3 sec)

▶ Performance: <8% thickness swelling after 4hrs boiling (EN 300 requirement: ≤15%)

Technical Specifications

Thickness: 12mm (±0.3mm tolerance)

Dimensions: 1250mm × 2500mm (customizable up to 2800×6000mm)

Density: 650±50kg/m³

Moisture Content: 6-9% (factory standard)

Fire Rating: Class B1 (EN 13501-1 certified)

Operating Temperature: -30℃ to 80℃

Packaging: Moisture-proof PE film + wooden pallet (80-100 sheets/pallet)

Core Features

1. Superior Water & Moisture Resistance

Impregnated with phenolic resin technology, featuring water absorption expansion rate <15% (24-hour immersion test). Effectively resists rainwater and humidity erosion, suitable for high-humidity regions and outdoor temporary structures.

2. High-Strength Load-Bearing Structure

Cross-layered orientation of mixed hardwood strands delivers bending strength ≥22MPa and modulus of elasticity >3500MPa, significantly outperforming conventional plywood. Ensures structural stability in construction applications.

3. Eco-Friendly & Safe Material

Made from sustainable mixed hardwoods (eucalyptus/poplar blend) with formaldehyde emission ≤0.3mg/L (CARB Phase 2 compliant). FSC® certified for responsible sourcing. Non-toxic and safe.

4. Precision & Workability

Surface flatness tolerance <0.5mm. Pre-milled edges minimize chipping. Compatible with nail guns and screws. Optimized for efficient cutting and grooving, reducing labor costs.

5. Large-Scale Supply Capacity

Fully automated production line with daily output of 500m³ (approx. 40,000 sheets). Supports OEM size customization. Global orders delivered within 15 days.
