Production Equipment
A complete production line for 25mm thick acoustic particleboard is a complex system integrating multiple processes including wood handling, flake preparation, drying, blending, forming, hot pressing, and finishing.
The following details the core equipment components and their functions:
 | 1. Raw Material Preparation Section |
Chipper: Breaks down raw materials such as logs, branches, and wood scraps into wood chips of required specifications.
Flaker: Further processes the wood chips into standard, uniform flat flakes. This is the core raw material for high-quality particleboard. For acoustic board, uniform flake geometry is crucial to ensure board density and structural stability.
| 2. Flake Preparation and Drying Section |
Crusher / Refiner: Re-crushes oversized flakes or coarse flakes from screening to obtain fine flakes of qualified dimensions.
Screening Machine: Classifies flakes by size. Typically separates fine surface-layer flakes from coarse core-layer flakes, preparing for differentiated blending and forming. This is key to ensuring a smooth surface and stable internal structure.
Dryer: Typically a rotary drum dryer, reduces the moisture content of flakes from an initial 30%-50% down to the required process range of 3%-5%. Consistent moisture content is essential for glue bonding quality and board performance.
| 3. Blending and Forming Section |
Blender: One of the core units of the production line. Precisely and uniformly mixes dried flakes with adhesive (e.g., UF resin, PF resin), waterproofing agent (wax), and other additives (e.g., specific fillers for enhanced sound insulation).
Surface & Core Blenders: Typically two separate systems for differentiated resin application on surface fines and core coarse flakes.
Forming Station / Forming Machine: Spreads the resinated flakes evenly into a continuous, mat-like board blank according to a set structure (usually 3-layer or multi-layer). Uniformity and stability of the forming process are critical for 25mm thick acoustic board. Forming heads are usually mechanical or air-assisted.
| 4. Pre-pressing Section |
Mat Conveying System and Pre-press: The loose, formed mat is first passed through a pre-press, which applies high pressure at room temperature to initially compact it. This provides sufficient strength and density for transportation into the hot press and helps remove air.
| 5. Hot Pressing Section |
Hot Press: The "heart" of the production line, determining the final board thickness, density, and mechanical properties.
Continuous Press: The preferred choice for modern, high-capacity, efficient lines. The mat is continuously pulled through a high-temperature, high-pressure press tunnel by steel belts. It allows smooth pressure and temperature control, ideal for producing large-format, varying thickness (especially thick boards like 25mm) high-quality boards with uniform density and stable quality.
Multi-opening Hot Press: Suitable for medium to low-volume production lines. Board blanks are loaded in batches and pressed simultaneously between multiple heated platens. For thick board production, precise control of pressure and temperature curves is critical to avoid defects like "blows".
Heating System: Provides a stable heat source for the hot press, commonly using steam, thermal oil, or electricity.
| 6. Finishing and Cutting Section |
Cooler and Turner: The boards exiting the hot press are at high temperature. They enter a cooler/turner for cooling and conditioning to release internal stresses and prevent warping.
Trim Saw and Cross-Cut Saw: After cooling, the continuous board strip is first trimmed on both edges, then cut transversely to specified lengths (e.g., 2440mm, 1220mm) according to order requirements.
Stacker: Automatically stacks the cut boards into piles for subsequent handling and storage.
| 7. Sanding and Quality Control Section |
Sanding Machine: Typically a wide-belt sander with multiple heads. Sands the top and bottom surfaces of the board to precise thickness, eliminating deviations and achieving a smooth, flat surface, providing a perfect substrate for laminating or direct use. For acoustic board, sanding precision is crucial for the final surface quality and appearance.
Quality Control System: Includes online density detection, thickness monitoring, etc., to ensure consistent product quality.
| Summary of Key Line Features: |
Designed for Thick Board: Robust forming and continuous press systems ensure stable mat formation and uniform pressing for 25mm thick boards.
High-Precision Blending and Forming: Ensures the internal structural gradient of the board, which is fundamental for achieving high density and excellent acoustic properties.
High Automation Level: The entire line, from raw material intake to finished product, is monitored by a central PLC control system, ensuring production efficiency and product consistency.
Production Process
A professional production line for 25mm thick acoustic particleboard is designed with the core objective of creating a board structure that possesses high density, multiple layers, and an internal composition that effectively dissipates sound wave energy. The entire process builds upon standard particleboard manufacturing but emphasizes enhanced precision and control at key stages.
Core Sound Insulation Principle: Sound insulation (airborne sound transmission loss) performance primarily depends on the board's surface density (mass per unit area), the damping characteristics of its internal structure, and its structural integrity. Heavier, denser, and well-laminated boards with a distinct layered structure yield superior sound insulation.
| 1. Raw Material Preparation and Flaking |
Process: Wood raw material (e.g., logs, branches, recycled wood) is processed into flakes of specific specifications using a chipper and a flaker.
Sound Insulation Focus:
Flake Classification: Flakes are strictly separated into fine surface-layer flakes and coarse core-layer flakes using a precision screening machine. This is the foundation for building a "graded-density structure." Uniform, fine surface flakes create a dense surface that effectively reflects some sound waves, while large core flakes allow for high surface density and create a complex internal path for sound wave propagation.
| 2. Drying and Blending |
Process: Classified flakes are dried in a dryer to reduce moisture content to the required level. They are then mixed with adhesive (e.g., UF resin), waterproofing agent (wax), etc., in blenders.
Sound Insulation Focus:
Differentiated Blending: This is one of the core steps for acoustic board production. Surface fines and core flakes are typically blended in separate blenders.
Core Flakes: The resin application might be slightly increased, or specific weighting fillers (e.g., heavy calcium carbonate) can be added specifically to the core layer. This aims to further increase the board's surface density, the most direct method for enhancing sound insulation.
Surface Flakes: Standard resin application is used to ensure surface hardness and smoothness.
Acoustic Additives: Special additives that increase the damping properties of the board can be introduced into the adhesive mix to enhance sound energy dissipation.
| 3. Forming and Pre-pressing |
Process: The resinated flakes are spread by a forming machine into a uniform mat following a "surface-core-surface" three-layer or multi-layer structure.
Sound Insulation Focus:
Graded-Density Forming: The forming process must be precisely controlled to ensure the creation of a high-density surface layer and a relatively loose but thick core layer. This structure effectively impedes sound transmission: the dense surface reflects some sound energy, and waves that penetrate into the core are repeatedly reflected and converted into heat through friction within the intricate network of flakes and voids. For a 25mm thick board, a stable, uniform core is critical.
| 4. Hot Pressing |
Process: The pre-pressed mat enters the hot press (a continuous press is highly recommended), where heat and pressure cure the adhesive, bonding the loose flakes into a solid board.
Sound Insulation Focus:
Pressure and Thickness Control: When producing 25mm thick boards, the pressure and temperature profile of the hot press must be meticulously set. Sufficient pressure ensures the board achieves high density (typically higher than standard particleboard), which is the physical basis for high sound insulation. Continuous presses provide more stable pressure, ensuring uniform density across the entire board area and preventing local defects that could compromise acoustic performance.
Preventing "Blows": During the pressing of thick boards, if steam and air are not adequately removed, it can cause blows (blisters), creating sound bridges that severely degrade insulation. Therefore, the pre-pressing and hot-pressing cycles must be optimized to ensure complete evacuation of internal gases.
| 5. Cooling, Cutting, and Sanding |
Process: The pressed board is cooled and conditioned, then cut to required dimensions, and finally sanded to precise thickness and smooth surface.
Sound Insulation Focus:
Ensuring Structural Integrity: Precise cutting ensures clean board edges, allowing for tight seams during installation to prevent sound leakage.
Controlling Thickness Tolerance: High-precision sanding is particularly important for 25mm acoustic board. Uniform thickness ensures proper sealing when installed, enabling optimal sound insulation performance. Any thickness variation can create gaps at joints, becoming a weak point for sound insulation.
In summary, producing acoustic particleboard does not rely on a single step but is achieved through a series of interconnected processes: "High-quality raw material classification + Differentiated blending/weighting of the core + Graded-density forming + High-precision hot pressing control." The precise management of each step collectively contributes to the board's exceptional sound insulation properties.
