What is the surface smoothness of formaldehyde free ENF grade environmentally friendly particleboard
source：www.sanjiachina.com Time：2025-04-28
The surface flatness of formaldehyde free ENF grade environmentally friendly particleboard is usually high, which is determined by its production process and equipment, as follows:
1. Excellent production process: During the production process, formaldehyde free ENF grade environmentally friendly particleboard undergoes multiple strict procedures, including screening, drying, gluing, paving, hot pressing, etc. Among them, the paving process adopts high-precision paving equipment, which can evenly lay the shavings on the conveyor belt to form a uniformly thick slab. The hot pressing process uses a large hot press machine, which controls the pressure, temperature, and time correctly to quickly solidify and form the slab under high temperature and pressure, thereby ensuring the overall flatness of the board.
2. Excellent raw materials: The shavings used to produce formaldehyde free ENF grade environmentally friendly particleboard are usually carefully screened and processed, with regular shapes and uniform sizes. At the same time, the adhesive used has good fluidity and permeability, which can be evenly distributed on the surface of the shavings, making the bonding between the shavings tighter and further improving the surface flatness of the board.
3. High precision sanding treatment: The hot pressed board will undergo sanding treatment, which is one of the key processes to ensure the surface flatness of the board. The sanding equipment adopts high-precision sand belts and excellent sanding processes, which can correctly control the amount of sanding and polish the surface of the board smoothly and flat. Generally, the thickness tolerance of the board can be controlled within ± 0.1mm, and the surface roughness Ra value can reach about 1.6-3.2 μ m.
However, the surface flatness of the board may also be affected by some factors, such as the accuracy of production equipment, the quality of raw materials, the control of production processes, and the conditions during transportation and storage. However, overall, under normal production and usage conditions, formaldehyde free ENF grade environmentally friendly particleboard can provide high surface flatness, meeting the requirements of most furniture manufacturing and interior decoration.
