Manufacturing method of bamboo fiberboard

It includes the following steps:

Step 1. The process of adding additives: using bamboo fiber and/or wood fiber as raw materials, polyurethane, isocyanate, epoxy resin, and soybean glue as adhesives, the raw materials are evenly sizing, and the quality of the adhesive accounts for 1% of the raw material quality ~3.5%;

Step 2. Drying process: dry the raw material after sizing and control its water content to 6%-14%;

Step 3: Pavement into a slab process: Weigh an appropriate amount of raw materials according to the plate width and thickness, and then pave the raw materials to form, and then undergo pre-pressing treatment to obtain a pre-formed blank;

Step 4. Microwave preheating process: the preformed slab is fed into a microwave heating device, and microwave heating is used to rapidly increase the temperature of the preformed slab to 80 ℃ ~ 180 ℃;

Step 5. Hot-press forming process: The pre-formed slab processed in step 4 is hot-press formed at a temperature of 180°C to 260°C, a forming pressure of 35kg/cm to 110kg/cm, and a holding time of 1min to 4.5 min.
