Application of Polyester Belt in Wood Panel Manufacturing

Application of polyester belt in wood panel manufacturing: a key link from fiber dehydration to board quality

In modern wood industry, from particleboard, MDF/HDF, to oriented strand board (OSB), the efficiency and quality of board production increasingly depend on the stability of front-end fiber treatment.

The production line of a wood factory may seem like physical processing of wood, but behind it is actually an industrial chain that heavily relies on solid-liquid separation capabilities. The wood pulp used in the fiber preparation stage has a high moisture content and lacks a stable, reliable, and efficient dehydration process. Subsequent drying, hot pressing, and paving processes will face higher energy consumption and greater fluctuations.

What are the difficulties in solid-liquid separation of wood fiber pulp?

The characteristics of wood fibers themselves determine that dehydration is not easy:

1. The fibers are soft and have a large specific surface area, making them prone to clumping and forming a water lock structure.

2. High slurry concentration and viscosity → require higher mechanical dewatering pressure.

3. Contains small particles and gelatinous substances → Easy to clog traditional filter cloth.

4. Different tree species and regions have significant differences in fiber content, resulting in noticeable fluctuations in filtration conditions.

The position of belt press filter in wood production

Belt Press Filter is one of the main equipment for dewatering wood fiber pulp.

Its advantages include:

1. Continuous operation and large processing capacity.

2. High dehydration rate, which can reduce the moisture content of wood fibers from 85-90% to 60-65%.

3. Low energy consumption and minimal damage to fiber structure.

4. Adapt to various wood fiber and pulp working conditions.

The three major functions of polyester mesh belt in belt press filter machine

(1) Filtration: Drain the water and retain the fibers.

(2) Bearing capacity: allowing fibers to maintain their structure under high pressure.

(3) Drainage: Multi dimensional drainage structure enhances the ability to control moisture content.

How does polyester mesh belt affect the final quality of wooden boards?

1. Determine the uniformity of fiber moisture content.

2. Determine the utilization rate of adhesive.

3. Determine production capacity and stability.
