Deaeration Belt for Prepress and Steam Injection process

In the modern production lines of density fiberboard (MDF) and particle board, pre-pressing machine and steam section are two core process links. As an indispensable auxiliary equipment in these two links, the performance of Deaeration Belt directly affects the quality and production efficiency of the board.

This article will analyze the application position and core role of deaeration belt in the production line, and provide some helpful information for the manufacturer of MDF/Particle board/OSB.

Application and function of Deaeration Belt

1. The Deaeration Belt used for prepress section

 Application location: The pre-press is located in the board forming stage, mainly used for preliminary compaction of wood fibers or chips, and discharge of excess gas and moisture.

 Core function: The Deaeration Belt ensures efficient discharge of gas and moisture during hot pressing through uniform air permeability in this link, avoiding bubbles or stratification inside the board, thereby improving density uniformity and structural stability.

2. The Deaeration Belt used for Steam Injection process

Application location: The steam injection equipment is usually located after hot pressing or in the gluing process, and accelerates the curing of the adhesive through high-temperature steam.

Core function: The Deaeration Belts needs to withstand the impact of high-temperature steam during this process, and evenly distribute the steam pressure to ensure that the glue in each part of the board is fully cured, enhancing the waterproofness and mechanical strength.

Performance requirements and selection key of Deaeration Belt

According to different process requirements, the selection of Deaeration Belt needs to take into account the following factors:

1. Air permeability

Pre-press section: Choose products with high air permeability to quickly discharge gas and moisture to prevent internal defects of the board.

Steam injection process: The air permeability must match the steam pressure to ensure that the steam penetrates evenly without damaging the belt structure

2. Heat resistance and chemical corrosion resistance

The temperature of the steam injection process can reach over 100°C.

The Deaeration Belt must be made of high temperature resistant materials and have the ability to resist steam corrosion.

3. Wear resistance and tensile strength

The continuous operation of the production line requires extremely high mechanical properties of the Deaeration Belt. Wear-resistant and tensile-resistant materials must be selected to reduce the frequency of downtime maintenance.

4. Adaptability and customized services

The size and pressure parameters of different production line equipment vary greatly. It is recommended to cooperate with professional suppliers, such as Huatao, to customize the Deaeration Belt according to the equipment requirements and provide technical support.

In the production of density board and particle board, the Deaeration Belt is not the core equipment, but it is the "invisible hero" to ensure quality and efficiency. When selecting the model, manufacturers of MDF/Particle board need to combine their own process characteristics and give priority to air permeability, temperature resistance and the supplier's technical support capabilities.
