Medium density fiberboard technology
1, stock preparation
The first step in the production process of medium density fiberboard is to prepare materials. The equipment mainly includes chippers, belt conveyors, screening machines, bucket elevators, and storage silos. The raw material for MDF production is mainly wood fiber raw material, which includes small diameter wood, branch lintel, fuel wood, and processing residues. The ideal stock material is 60% to 70% of softwood, and 30% to 40% of hardwood. Skin content should not exceed 5%.
2, the preparation of fiber
The preparation of fiber is mainly fiber separation, and it is the core link of MDF production process. The equipment for fiber separation uses wood chip silos (or preheated silos), small hoppers, thermal mills, paraffin melting and application devices, and sizing metering devices
