A complete production line for an annual output of 150,000 m³ of moisture-resistant particleboard is typically composed of the following eight sections connected in series, forming a highly automated and continuous production system:
1. Raw Material Preparation Section: Reception, crushing, screening, storage.
2. Particle Preparation Section: Flaking, refining, classification.
3. Drying Section: Removing moisture from the particles.
4. Blending and Glue Application Section: The core for moisture resistance, where adhesives and additives are uniformly applied to the particles.
5. Forming and Pre-pressing Section: Forming an even mat and preliminary compression.
6. Hot Pressing Section: Curing and forming the mat under high temperature and pressure.
7. Finishing Section: Cooling, trimming, sanding.
8. Intermediate Storage and Automated Control System: The "nerves" and "blood vessels" connecting all sections.
1. Raw Material Preparation Section
Debarker (Optional): Required if using roundwood.
Chipper: Chips raw materials like roundwood, small-diameter logs, and wood residues into suitable wood chips. A large-scale disc chipper is typically selected for this capacity, offering high power and output.
Screening and Re-crushing System: Uses equipment like swing screens to send eligible chips to the next section, return oversized chips for re-crushing, and send fines to be used as fuel.
2. Particle Preparation Section (Determines Particle Quality)
Ring Flaker: A core piece of equipment. Flakes the wood chips into particles of specified size. For 150,000 m³ capacity, a large, high-precision ring flaker is needed to ensure uniform particle shape and smooth surfaces.
Refiner: Refines the surface of some particles to create fines used for the surface layers of the mat.
Particle Classification System: Uses air or mechanical screening to precisely separate particles into surface-layer fines and core-layer coarse particles. This is key to ensuring good surface quality and internal structural strength.
3. Drying Section
Rotary Drum Dryer: The mainstream choice. A line of this capacity typically requires 2-3 large rotary drum dryers to dry surface and core particles separately. Temperature, air flow, and duration must be precisely controlled to achieve uniform moisture content (typically reduced to 2%-4%).
4. Blending and Glue Application Section (Core of Moisture Resistance)
Glue Application System:
Core Adhesive: The key to moisture-resistant particleboard is the use of moisture-resistant/waterproof adhesives, typically Melamine-Urea-Formaldehyde (MUF) resin or the higher-grade Isocyanate (MDI) glue. MDI-based boards have very low formaldehyde emissions (can reach ENF/No Added Formaldehyde grade) and excellent waterproof properties.
Blender: A high-speed rotary ring blender is the standard. It uniformly mixes glue, hardener, and waterproofing agent (paraffin emulsion) with the particles in a mist form within seconds (2-3 seconds).
Waterproofing Agent Addition System: Must be equipped with high-precision metering and injection systems to ensure accurate and uniform paraffin emulsion dosage.
5. Forming and Pre-pressing Section
Mechanical Forming Station: Uses multi-head weigh scales + mechanical scatter heads to continuously and evenly form a mat with a "core-surface-core-surface" structure, ensuring density gradient and smoothness.
Pre-press: Applies preliminary compression to the fluffy mat to increase strength for easier handling and loading into the hot press. Typically a continuous belt pre-press.
6. Hot Pressing Section (The "Heart" of the Line)
Continuous Press: For a 150,000 m³ capacity, a continuous press is the necessary choice. It cures the mat by conveying it through heated platens via a continuous steel belt under set temperature, pressure, and time.
Advantages: High output, uniform board density, excellent board flatness, suitable for thin and thick boards.
Specifications: The press is typically over 30 meters long, with pressure reaching tens of thousands of tons. The heating system (thermal oil or steam) must be stable and reliable.
7. Finishing Section
Cooler and Turner: Cools the hot pressed boards to room temperature, releasing internal stresses.
Cross-Cut and Edge Trimming Saws: Cuts the continuous pressed board strip into required-sized rough boards.
Stacker: Automatically stacks the rough boards.
Sander: A wide-belt sander, usually in a combination like "one coarse, one fine" or "two coarse, one fine", used for calibrating thickness and improving surface quality. For this capacity, a heavy-duty 6 or 8-head sander is needed to ensure high productivity and sanding accuracy.
8. Intermediate Storage and Automated Control System
Storage System: Includes particle silos, dry silos, finished product buffer zones, etc., connected by belt conveyors, bucket elevators, and screw conveyors to ensure production continuity.
Automated Control System (DCS/PLC): The "brain" of the entire line. Monitors and sets parameters for all equipment from a central control room (e.g., temperature, pressure, speed, ratios), enabling production data management, fault diagnosis, and energy optimization.
Beyond using MDI or MUF adhesives, the equipment itself must support moisture resistance:
1. Particle Morphology Control: High-quality ring flakers and refiners ensure uniform particle shape and thickness, allowing for the formation of a complete glue film during blending that effectively blocks moisture.
2. Precise Glue and Wax Application: High-speed blenders and precision metering pumps are crucial for uniform distribution of glue and wax. Any inconsistency can lead to localized weak spots in moisture resistance.
3. Accurate Hot Pressing Process: The continuous press provides extremely stable pressing conditions, ensuring the core layer cures completely, resulting in a dense, waterproof board structure.

Moisture-resistant particleboard, having overcome the common particleboard's weakness of being susceptible to moisture, has a very wide range of applications. Its main uses can be categorized as follows:
I. Furniture Manufacturing
This is the core application area for moisture-resistant particleboard, especially in environments sensitive to humidity.
1. Kitchen Furniture:
Cabinet Carcasses: This is the primary use for moisture-resistant particleboard. Kitchen environments are humid with frequent steam. Ordinary particleboard can easily swell and deform, whereas moisture-resistant board effectively resists dampness, ensuring cabinets remain stable and durable.
Bathroom Vanities: Bathrooms have even higher humidity levels, making moisture-resistant board an ideal material for vanity cabinets.
2. Office and Commercial Furniture:
Used for office partitions, filing cabinets, work station desktops, etc. It performs stably in commercial spaces that require regular cleaning or where humidity levels may fluctuate.
3. Residential Furniture:
Panel Furniture: Used for making wardrobes, bookcases, TV cabinets, etc. Especially in regions with high humidity or bedrooms without dry-wet separation, using moisture-resistant board can extend furniture life.
Interior Doors and Door Frames: Can be used as the core material for interior hollow core doors, helping to prevent deformation caused by weather changes.
II. Construction and Interior Decoration
In construction, moisture-resistant particleboard is often used as a substrate or structural material.
1. Concrete Formwork:
After special treatment (e.g., film overlay), moisture-resistant particleboard can be made into concrete formwork for construction. Its moisture-resistant properties ensure it can withstand water erosion during concrete pouring, allowing for multiple reuses.
2. Floor Underlayment:
Installed on the subfloor before laying wooden flooring or carpet, moisture-resistant particleboard serves as an underlayment, providing leveling, moisture resistance, sound insulation, and enhanced elasticity.
3. Substrate for Walls and Ceilings:
In areas like bathrooms and kitchens, it can be used as a substrate on walls or ceilings before tiling or installing decorative panels, protecting against moisture from the walls.
4. Stair Treads:
Used as the base material for stairs, later covered with other decorative finishes.
III. Packaging and Transportation
1. Heavy-Duty Packaging:
Used to make crates, pallets, and dunnage that require strength and moisture resistance. This is particularly useful for export shipping or storage environments, effectively protecting goods like machinery and electronic products.
IV. Other Specialized Uses
1. Display Shelving:
Used for shelving in supermarkets, retail stores, and warehouses. Warehouse environments can be damp, and shelving needs to bear weight, which moisture-resistant board can handle.
2. Vehicle and Ship Interiors:
Used for interior partitions, cabinets in buses, trains, and ships. These environments require materials with good fire-retardant and moisture-resistant properties.
Compared to standard particleboard, the advantages of moisture-resistant particleboard are:
Durability: Resists swelling, warping, and cracking in humid environments, offering good dimensional stability.
Wide Applicability: Expands the application scenarios of particleboard, especially in areas traditionally unsuitable for wood-based panels like kitchens, bathrooms, and basements.
Cost-Effectiveness: Offers a significant cost advantage over solid wood or Medium-Density Fiberboard (MDF) in applications where moisture resistance is required.
