slice
The logs are transported into the warehouse by the transporter, sliced ​​by the slicing machine, and then entered into the wood chip library, and screened through the vibrating screen, the uniform wood chips are screened out, and then the “washing†process is entered.
Washed
The water washing system cleans the cut wood chips to remove the mud, sand and other impurities contained in the wood chips, and ensures that the clean wood chips are transported to the next process.
Cooking
Vertical cooking cylinders are an important part of the production line in which the chips are cooked and softened under saturated steam at a pressure of 6-8 bar and a temperature of 150-160 °C. The residence time of the chips in the cooking cylinder is 1-3 minutes. The vertical cooking cylinder is a pressure vessel that ensures the removal of harmful substances that may be present in the original wood.
Hot grinding
Hot grinding is a very critical production process in which the cooked wood chips are separated into fibers in a high speed rotating plate. The hot mill has a chamber pressure of 8-9 bar, a temperature of 140-150 ° C, a total installed capacity of 7000 kW, and a rotational speed of 1500 rpm. The hot grinding system is a high temperature and high pressure system that also acts as a fumigation effect on wood chips and fibers.
dry
The drying system is the largest air delivery system in the production line. The system uses high temperature flue gas as the heating medium to dry the fibers to the specified dry humidity. Further removal of harmful substances in this system.
Paving
The dried fibers are screened, and the qualified fibers are separately metered by the conveyor and the panel scales and sent to the paving machine to lay out a uniform and flat slab.
Hot pressing
The continuous hot press is the most critical equipment in the production line. This equipment quickly cures the adhesive in the slab by the precise combination of temperature, pressure and production speed, and presses the slab.
Health
The formed plain plates are stacked in a special area in a single order, allowing it to self-regulate and fully release the physical stress. This process is about two days, called health. The properties of the board after curing will be more stable and not easily deformed.
Sanding
The surface of the fiberboard is machined and corrected for thickness using a sander. Remove the pre-cured layer on the surface of the board to increase the surface usage of the board.
Cutting
The dimensions of the board are specified according to the specifications required by the customer.
Storage
Pack the finished product, number it, and put it into the warehouse. Well-ventilated and constant temperature warehouses ensure product quality stability.
