VERFAHREN ZUR HERSTELLUNG UND MAGNETISIERUNG EINER MAGNETPULVER ENTHALTENDEN BITUMENFOLIE

A bitumen film containing magnetic powder is heated prior to magnetization to a temperature enabling the magnetic powder particles to be oriented according to the effect of the magnetic field. The bitumen film is sufficiently cooled after magnetization in order to preserve the magnetization, whereby...

Beschreibung
Zusammenfassung:	A bitumen film containing magnetic powder is heated prior to magnetization to a temperature enabling the magnetic powder particles to be oriented according to the effect of the magnetic field. The bitumen film is sufficiently cooled after magnetization in order to preserve the magnetization, whereby the orientation of the magnetic powder particles, which is adjusted during magnetization, is maintained.
