Abstract (en)
[origin: EP0504130A2] According to the method for the manufacture of lignocellulosic fibre products, for example fibreboards, precomminuted lignocellulosic material, such as chips or the like are, after squeezing out the excess water, digested under pressure and then beaten to give fibres which, after the addition of glue prepared with water, are dried and then passed to further processing, for example to board presses. To reduce pollution of the environment, the excess water squeezed out of the lignocellulosic material is - if appropriate, mixed with fresh water - fed to the glue preparation. For permanent pH adjustment of the glue water to the lignocellulosic fibres, a pH control system is provided.
