CELLULOSE MATERIAL HAVING IMPREGNATION AND USE OF SAID CELLULOSE MATERIAL

摘要

The invention relates to a cellulose material consisting of cellulose fibres (12) that have an impregnation. According to the invention an impregnation (13) of the cellulose fibres consists of polyethyleneimine (13). The impregnation forms a type of network (14), which can reduce the specific resistance of the cellulose material owing to the electrical conductivity of said network. The cellulose material can thereby be advantageously adapted to corresponding uses in terms of the electrical properties thereof. A use of the cellulose material is therefore also the electrical insulation of transformers, the cellulose material in this case being soaked in transformer oil and an adaptation of the specific resistance of the cellulose material to the specific resistance of the oil leading to improved dielectric strength of the transformer insulation. The invention further relates to a method for producing the above-described cellulose material, which has a suitable impregnation step for the cellulose material.
