A complete No Added Formaldehyde Particleboard Production Line primarily consists of the following core systems:
1. Raw Material Preparation Section:
Chipping & Flaking System: Processes logs, small-diameter wood, or wood residues into qualified flakes using a chipper and flaker.
Screening & Milling System: Precisely classifies flakes into face and core layers via vibrating screens. Oversized flakes are sent back to a mill for re-processing, ensuring uniform particle geometry.

2. Drying & Sorting Section:
Rotary Drum Dryer: Employs high-efficiency, stable rotary dryers to reduce the moisture content of flakes to the required range, ensuring subsequent gluing and pressing quality.
Pneumatic Separator: Further cleans and sorts dried flakes, removing impurities like metals and sand, and precisely separates face and core layer flakes.

3. Blending & Gluing Section (Core Technology Segment):
Formaldehyde-Free Adhesive Supply System: Features dedicated storage, pre-heating, and precise metering/dosing systems for MDI or bio-adhesives. Due to the properties of MDI, this system often requires temperature control and nitrogen blanketing.
High-Speed Blender: Uses dynamic or static high-precision blenders to thoroughly and uniformly mix the formaldehyde-free adhesive, waterproofing agent (e.g., wax), and other additives with the face and core layer flakes. Resin application is precisely controlled by computer.

4. Forming & Pre-Pressing Section:
Mechanical/Pneumatic Forming Station: Lays the resinated face and core layer flakes into an even, consistent mat with a predefined gradient structure.
Pre-Press: Subjects the loose mat to cold pre-pressing to increase its initial strength for easier handling and feeding into the hot press, while accurately controlling mat height.

5. Hot Pressing & Cooling Section:
Continuous Press: The heart of a modern production line. The mat passes continuously through the press under high temperature and pressure, causing the formaldehyde-free adhesive to cure rapidly and form a solid board. Precise control of temperature, pressure, and speed is critical for achieving desired density, thickness, and physical properties.
Star Cooler: The hot board immediately enters a star cooler for gradual cooling. This process releases internal stresses, stabilizes board dimensions, and prevents warping.

6. Finishing & Sanding Section:
Edge Trimmer & Cross-Cut Saw: Cuts the continuous board strip into required-sized panels.
Stacking & Intermediate Storage: Stacks the panels for curing, allowing further stabilization of board properties.
Sanding Line: Calibrates the panel surface through sanding to achieve precise thickness and a smooth, flat surface, ready for laminating or direct use.

7. Central Control System:
Integrates PLCs and industrial computers to monitor and automatically adjust process parameters (e.g., temperature, pressure, speed, resin dosage, moisture content) in real-time, ensuring stable production and consistent product quality.
The production process of No Added Formaldehyde Particleboard is highly automated and continuous. Its key distinction lies in the use of formaldehyde-free adhesives (like MDI), which necessitates specific requirements in the blending and hot pressing stages due to their unique properties.
The entire process can be broken down into the following key stages:
Stage 1: Raw Material Preparation
1. Raw Material Handling & Chipping: Raw materials (small-diameter logs, wood residues, etc.) are debarked and chipped into small wood chips.
2. Flaking & Screening: The wood chips are converted into flakes in a flaker. These flakes are then screened and sorted by size into Face Flakes (finer) and Core Flakes (coarser). Oversized flakes are re-processed.
Stage 2: Drying & Blending (The Critical Differentiator)
3. Drying: The sorted face and core flakes are dried separately in a Rotary Drum Dryer to achieve a very low and precise moisture content (typically 2%-4%). This is crucial because MDI is highly sensitive to moisture.
4. Blending (Key Technology): The dried flakes are accurately metered into High-Speed Blenders.
Formaldehyde-free adhesive (e.g., MDI) and other additives (e.g., wax) are thoroughly and uniformly mixed with the flakes.
Core Difference: The blending system must be highly precise to ensure perfect coating and prevent pre-curing of the adhesive, requiring specialized equipment (sometimes with nitrogen blanketing for MDI).
Stage 3: Forming & Hot Pressing
5. Forming: The resinated face and core flakes are spread by a Forming Station into a continuous, uniform mat with a "face-core-face" layered structure.
6. Pre-Pressing: The loose mat is lightly compacted in a Pre-Press to remove air and gain initial strength for handling.
7. Hot Pressing (Curing): The mat enters a Hot Press (often a Continuous Press). Under specific heat, pressure, and time, the MDI adhesive undergoes a chemical reaction (polymerization) with the wood, curing and bonding the flakes into a solid board. The process parameters are optimized for MDI's characteristics.
Stage 4: Finishing
8. Cooling & Conditioning: The hot board is immediately cooled in a Star Cooler to release internal stresses and stabilize dimensions. Stacking for conditioning allows further property stabilization.
9. Trimming & Sanding: The continuous board is trimmed to size and then passes through a Sanding Line to achieve precise thickness and a smooth surface.
10. Inspection & Packaging: Finally, the boards are inspected for quality and packaged for storage/shipment.
Ultimate Eco-Friendliness: Eliminates formaldehyde addition at the source, producing healthy and safe panels that comply with top international regulations like CARB NAF and EPA TSCA Title VI.
Excellent Physical Properties: MDI adhesive grants the boards superior mechanical strength, moisture resistance, and screw-holding power, with some properties exceeding those of traditional UF-bonded particleboard.
High Automation: High degree of automation from raw material to finished product reduces manual intervention and enhances production efficiency and stability.
Flexibility & Customization: The line configuration and process recipe can be adjusted according to client needs to produce No Added Formaldehyde Particleboard in various thicknesses, densities, and specifications.
Energy Efficiency: Incorporates advanced heat recovery systems and efficient drying technology to reduce overall energy consumption.
The No Added Formaldehyde Particleboard produced by this line is widely used in:
High-End Furniture Manufacturing: Kitchen cabinets, wardrobes, bookcases, etc.
Interior Decoration & Flooring Substrate: Especially for spaces with high demands for indoor air quality, such as hospitals, schools, hotels, and kindergartens.
