DM particleboard or Tablex is a particleboard of wood fibres combined with synthetic resins using high pressure and temperature. It is used to manufacture all types of furniture where weight is not a problem. The following is describes its manufacturing process:
The process begins with wood chips that are treated with steam. The wood particles formed are taken to tubs where a paste is formed with 3% wood. When the paste is taken out of the tubs, the emulsion and the urea-formaldehide glues are added.
A blanket is formed and passed through a conveyor belt;it is then passed to an “elevator” that holds about 25 units.
From there, the plates go to 25 presses that compress the blanket, drain the water, and polymerize the glues, forming the board.
The press is at a temperature of 200 °C and a pressure of 50 Kg. It acts for 5 minutes.
