摘要:
An insulator with a molding made of ceramic and a hydrophobic coating applied to the surface of the molding is disclosed, the hydrophobic coating comprising a plasma polymer having been applied directly to the ceramic. The previously customary glaze on the surface of the ceramic is replaced by the plasma polymer. Such an insulator has high long-term stability with regard to its electrical insulating capability. It is possible to dispense with complicated shaping of the molding to increase the leakage path over the surface of the ceramic and with the application of a glaze, which means a considerable cost saving.
摘要:
An electrical insulator is produced by coating a molded part of the insulator with a hydrophobic plasma-polymer coating. The plasma-polymer coating is produced by igniting a plasma in a non-polar working gas or a working gas having non-polar groups at a working pressure of between 0.001 Pa (1·10−5 mbar) and 50 Pa (5·10−1 mbar). The electrical power input per chamber volume lies between 0.5 and 5 kW/m3, the gas flow per chamber volume lies between 10 and 1000 sccm/m3. A durable, hard and hydrophobic plasma-polymer coating is created, the quality of which is independent of the material of the molded part.
摘要:
The invention relates to a product (11) with a laminated system (13; 15) consisting of at least one covering layer (15) and a moulding layer (13) arranged between the covering layer (15) and the product (11), wherein the moulding layer (13) is a plasma-polymeric layer that moulds the contours of the product (11) and adheres more firmly to the covering layer (15) than to the product (11). It further relates to a process for producing such a product (11) with a laminated system and to a process for producing a moulding negative and to a process for producing a positive model of (i) parts of the surface or (ii) the surface of a product.
