Deep technical annotation
1. Design of drying tower thermal efficiency
Adopting three-channel counter-flow heat exchange:
▸ Channel 1 (high-temperature zone): Inlet flue gas at 350℃ → Sawdust moisture content reduced from 45% to 20%
▸ Channel 2 (medium-temperature zone): 180℃ balanced evaporation → Moisture content 20% → 8%
▸ Channel 3 (low-temperature zone): 120℃ slow drying → Final moisture content 3 ± 0.5%
2. Continuous press machine precision control
Thickness adjustment response chain:
Thickness gauge data → Siemens PLC → Hydraulic servo valve (response time 80ms) → Partitioned cylinder displacement
During production of 22mm plates:
▸ Pressure zones 1-3: High-pressure zone (4.5MPa, 210℃) for rapid thickness setting
▸ Pressure zones 4-6: Medium-pressure zone (3.2MPa, 200℃) for curing the adhesive layer
▸ Pressure zones 7-8: Low-pressure zone (1.8MPa, 190℃) for stress release
3. Customized production verification data
Customized project | Measured performance |
2800mm ultra-wide plate | Density deviation ≤ 2.8% (full width) |
6mm thin plate continuous production | Plate tensile strength ≥ 18MPa (EN 319 standard) |
Flame-retardant plate (OI 32%) | Formaldehyde emission 0.025mg/m³ (F★★★★ grade) |
