Information

The production method of customized Plain Particle Board is divided into flat pressing method of intermittent production and extrusion method and roll pressing method of continuous production according to its different slab forming and hot pressing process equipment. In actual production, the flat pressing method is mainly used. Hot pressing is a key process in the production of the customized Plain Particle Board. Its function is to solidify the rubber in the slab, and to consolidate the loose slab into a board with a specified thickness after pressing. Let's take a look at what its process requirements are!
1. Appropriate moisture content. When the water content of the surface layer is 18-20%, it is beneficial to improve the bending strength, tensile strength and surface finish, and reduce the possibility of bubbling and delamination of the slab during pressure relief. The moisture content of the core layer should be appropriately lower than that of the surface layer to maintain proper planar tensile strength.


2. Proper hot pressing pressure. Pressure can affect the contact area between the shavings, the thickness deviation of the board and the degree of rubber transfer between the shavings. According to the different density requirements of the product, the hot pressing pressure is generally 1.2 to 1.4 MPa.
3. Appropriate temperature. Excessive temperature will not only decompose the urea-formaldehyde resin, but also cause partial pre-curing of the slab when the temperature rises, resulting in waste.
4. Appropriate pressurization time. If the time is too short, the middle layer resin cannot be fully cured, the elastic recovery of the finished product in the thickness direction will increase, and the plane tensile strength will be significantly reduced.
In summary, it is an introduction to the process requirements of the customized Plain Particle Board. You can learn more about it.
