MDF (Medium density fiberboard) powder coating
Introduction
Due to the good application prospects and advantages of MDF powder coating technology itself (see attached table), it has long been one of the main development directions of the powder coating industry and even the entire furniture industry. Standard has invested heavily in research and development in this field. At present, MDF technology has basically matured and has the conditions for large-scale promotion and application. And it is creating more and more efficient and fast construction efficiency, creating greater value for customers. With the increasing awareness of environmental protection and health, the relevant environmental protection laws and regulations are becoming more and more stringent, which will greatly expand the application field or space of powder coatings.
Powder coating MDF powder spraying technology vs liquid coatings
| Project | Powder coating | Liquid coating |
|---|
| Economical |
Low overall cost (coating + labor + energy consumption + storage), powder coating overall cost 80-150RMB/m² |
Low overall cost (coating + labor + energy consumption + storage), liquid coating overall cost 200-150RMB/m² |
| Environmentally friendly |
Construction environment, no volatility, no odor, no sewage; finished product zero VOC, and can effectively seal harmful substances in the board, healthy and environmentally friendly. Coatings can almost 100% utilize |
High VOC, up to 31 kinds of chemical poisons volatilize, especially highly toxic substances such as benzene, toluene, xylene and diisocyanate. The effective utilization rate of the coating is low, and formaldehyde is released in the later stage. |
| Process limitations |
Can handle special-shaped parts; convenient for the plate to handle chamfers and chamfers, the product is more beautiful and durable |
The process is complex, 6-10 processes, and cannot handle special-shaped workpieces. Special edge sealing treatment is required in the later stage, and it is easy to crack |
| Coating efficiency |
Fast curing speed, simple process: 1-2 processes take 2-4 hours to construct, low storage space requirements |
Complex process, 6-10 processes, construction time is 6-12 days, and more labor is occupied. Slow curing speed, high storage space requirements |
| Coating performance |
Excellent coating performance, good chemical and solvent resistance, can effectively seal formaldehyde |
Coating performance varies greatly according to different varieties. Poor water resistance, wear resistance and chemical resistance, poor sealing of volatile substances such as formaldehyde |
