Definitions
- the invention relates to a method for hydrophilizing surfaces, in particular surfaces of motor vehicle windows.
- the method according to the invention with the features mentioned in claim 1 offers the advantage that a relatively long-lasting hydrophilization of surfaces is possible in a simple manner.
- an influencing of the molecular structure can be achieved on the surface of the disks, which leads to a reduction of limiting stresses between the surface and of moisture that hits the surface, so that a much larger spread of moisture drops on the surface is possible.
- a thin film forms on the surface hydrophilized by means of the corona discharge, the surface of which runs essentially parallel to the surface of the pane, so that a change in the angle of refraction of transmitted light does not change, particularly when used on motor vehicle panes occurs.
- Figure 1 is a schematic view of the corona treatment of surfaces
- Figure 2 is a schematic view of an arrangement for corona treatment of surfaces of motor vehicle windows.
- Description of the embodiments 1 shows an object 10 whose surface 12 is to be hydrophilized.
- an electrode 14 is guided over the surface 12 at a distance a.
- the electrode 14 can, for example, be designed in the form of a point, line or area.
- the electrode 14 is connected to an AC voltage source 16, which provides a high-frequency AC voltage.
- the level of the AC voltage is, for example, 10 kV with a frequency of 300 KHz.
- the surface treatment can be carried out by xy rasterization of the surface 12 by the electrode 14. In the case of linear electrodes 14, a movement can only take place in the x direction, while in the case of planar electrodes, for example, a single approach to the surface 12 is sufficient.
- the intensity of the surface treatment can be varied on the one hand by varying the distance a, by the duration of the treatment per unit area or by the level of the AC voltage of the AC voltage source 16.
- FIG. 2 shows purely schematically a possible arrangement on a windshield 20 of a motor vehicle, not shown.
- the AC voltage source 16 can be combined in a suitable manner with a wiper blade 22 of a windshield wiper system.
- the wiper blade 22 is moved back and forth over the windshield 20 in accordance with the double arrow 24 shown.
- the electrode 14 is now integrated into the wiper blade 22, or if the wiper blade 22 has the electrode 14, for example as a line electrode or as point electrodes arranged at a distance from one another along the wiper blade 22, the surface of the windshield 20 can be hydrophilized during the wiping movement. This advantageously makes it possible, at any time, either during the wiping process of the wiper blade 22 or at predetermined time intervals, to carry out the hydrophilization of the windshield 20 by means of the corona discharge 18.
- an external device for corona treatment of the windshield can also be used. This could be part of stationary car washes or the like, for example. It is also conceivable to equip petrol stations, workshops and so on with devices for hydrophilizing motor vehicle windows by means of corona discharge.
