Verfahren zur Erhöhung des elektrischen Durchschlagswiderstandes von Filmen aus Zellnloseestern oder-äthern.
EMI1.1
Filme aus Estern oder Äthern der Zellulose in gleicher Weise zu behandeln, hat aber keine praktischen Ergebnisse gezeitigt, da die so behandelten Filme ausserordentlich bruchig und daher unverwendbar waren.
Es wurde nun überraschenderweise gefunden, dass die dielektrische Eigenschaften der Filme aus Zelluloseäthern und -estern, ohne die Geschmeidigkeit zu beeinträchtigen, dadurch erhöht wird, wenn man sie mit Paraffinölen. Transformatorenölen usw. überhaupt mit Ölen, welche hohen Durchschlags-

PATENT-ANSPRÜCHE :
1. Verfahren zur Erhöhung des elektrischen Durchschlagswiderstandes von Filmen aus Zelluloseestern und-äthern. dadurch gekennzeichnet, dass dieselben mit Ölen von hohem Durchschlagswiderstand, wie Paraffinölen. Transformatorölen usw., gestänkt werden.

Process for increasing the electrical breakdown resistance of films made from cellless esters or ethers.
EMI1.1
Treating films made from esters or ethers of cellulose in the same way has not produced any practical results, since the films treated in this way were extremely brittle and therefore unusable.
It has now surprisingly been found that the dielectric properties of the films made from cellulose ethers and esters, without impairing the suppleness, are increased when they are mixed with paraffin oils. Transformer oils etc. with oils that have high dielectric strength
EMI1.2
but also look more flexible than previous films.
PATENT CLAIMS:
1. Process for increasing the electrical breakdown resistance of films made from cellulose esters and ethers. characterized in that the same with oils of high dielectric strength, such as paraffin oils. Transformer oils, etc., are soaked.
