The process > Process description

In a very simple way, the FIBROLINE process can be described as follows:

- a system of 2 face to face electrodes is connected to an alternative high tension generator, for instance 10 to 50 kV

- the electrodes are protected by a suitable dielectric material

- space between the two electrodes varies according to the thickness of the fibrous support to be impregnated

- the unit also incorporates high tension protection devices and an ozone destruction unit.

The right quantity of powder is scattered onto the fibrous support.

The fibrous support is then placed between the two dielectrics, and a strong alternative electric field is created by the high tension applied to the electrodes.

At the end of the treatment, all the powder scattered on top of the support finds itself inside.

In most cases, a 10s residence time is sufficient, and leads to a homogeneous distribution of the powder inside the support.

It is important to notice that no raise in temperature occurs inside the machine, and no static electricity remains inside the material at the end of the treatment.

Energy consumption of the whole system is very low: for instance, a 4m long and 1.20m wide unit running at 10m/min (impregnating up to 1T/h material) requires less than 15kW.
