company news about MDF powder spraying technology

Due to the increasing awareness of environmental protection and the continuous improvement of environmental regulations, traditional solsol-based coatings contain volatile harmful objects and harmful air pollutants, and powder coating spraying can make the coating have good scratch resistance and stain resistance, and has a variety of colors and effects of the surface decoration appearance. Therefore, the use of powder coating is a trend, from the overall point of view, MDF powder coating cost is lower than the traditional coating process, and does not produce volatile organic compounds, high efficiency, good mechanical properties of the film.

Compared with other surface spraying, powder coating film is not easy to damage, the workpiece generally does not need to be recoated after powder spraying, the workpiece rework rate is low, saving costs: and powder coating has excellent adhesion, hardness, impact resistance, wear resistance and chemical stability; Powder coating provides greater flexibility in the design of MDF shapes, and is suitable for painting irregular shapes such as curved surfaces. Coating products can achieve seamless edges: Powder coating in the spraying and drying process without solvent production, reduce environmental pollution, overspray powder can be recycled, simple process operation, high utilization rate, good decorative effect, high spraying efficiency, energy saving. MDF powder spraying market demand is huge, but China has not yet formed large-scale MDF powder spraying industrial management, the main reason is that MDF powder spraying technology content is relatively high, the need for a certain early investment.

In order to obtain high quality, especially to ensure that the edge of the board does not crack for a long time, it is necessary to master the quality control of the MDF, the design and control of the spraying production line, the performance design of the powder coating and the quality inspection of the finished product, and the technical support of these four aspects. The purpose is to provide a MDF powder spraying process which is easy to operate, good implementation effect, can effectively avoid the side cracking of MDF, excellent corrosion resistance, chemical resistance, good film shrinkage, high hardness, good wear resistance, corrosion resistance and excellent electrical insulation properties.
