资源简介:
The invention relates to a method for applying glue to comminuted lignocellulosic particles (10) in the course of the production of material panels, wherein a glue which can be hardened by temperature and / or the addition of hardeners and comprises at least one formation of colloids is via a volume flow-adjustable conveying device (2) and conveying lines ( 15a, 15c) is brought to a dispersion unit (1), in which the glue is homogenized by means of a comminuting device and a mixing device and is finally conveyed via conveyor lines (15a) to nozzle arrangements (6) which spray the glue onto the particles (10) in a mixing chamber (5). In order to ensure that a glue that is used for wetting lignocellulosic particles, in particular wood chips, has a sufficient viscosity and reactivity for the production of the material panels, it is provided that the amount of glue conveyed is determined and the speed of the dispersion unit is determined in an evaluation unit (8) is assigned and this speed is then set.
