[0048] Production of MDF from wood waste can be accomplished using the following steps:
[0049] (1) Cut wood waste into pieces with a length less than 5 cm and a width less than 1 cm.
[0050] (2) Sieve the wood fragments obtained above to remove silt and debris with a particle size of less than 0.2 cm.
[0051] (3) Transport the screened wood chips to the cooking tank, and iron removal treatment is required during the transport process.
[0052] (4) After transporting the wood fragments into the cooking tank, add an appropriate amount of water to soak for 10-30 minutes; and inject steam from the top or upper part of the cooking tank, the pressure in the cooking tank is 0.16-0.2Mpa, and cook for 1-4 minutes to ensure The water content of the cork chips obtained after cooking is 70-85%.
[0053] (5) The cork chips obtained by cooking are transported to a disc refiner for grinding until the fiber length is less than 0.8 cm.
[0054] (6) Add modified paraffin and glue to the ...
