An operation that uses electroplating to precisely replicate the shape of an object. The master mold used for electroforming is called an electroform. The main types of electroplating used are copper, nickel, and iron. Electroforms include non-metallic ones such as synthetic resin, beeswax, gypsum, rubber, and wood, and metallic ones such as lead, low-melting-point lead alloys, copper, nickel, and silver. For non-metallic electroforms, it is necessary to apply an electrically conductive film by chemical plating or sputtering of silver, or by applying a suspension of graphite powder or copper powder. This film also acts as a release film after electroforming. For metallic electroforms, it is necessary to apply a release film, Source: Morikita Publishing "Chemical Dictionary (2nd Edition)" Information about the Chemical Dictionary 2nd Edition |
電気めっきを利用して物体の形を精密に複製する操作.電鋳をするために使用される母型を電型という.電気めっきの種類としては,おもに銅,ニッケル,鉄が用いられる.電型としては,合成樹脂,みつろう,セッコウ,ゴム類,木材のような非金属のものと,鉛,低融点鉛合金,銅,ニッケル,銀などの金属電型がある.非金属電型の場合は,銀の化学めっきあるいはスパッタリング,黒鉛粉,銅粉などの懸濁液の塗布などにより電気伝導性膜をつける必要がある.この膜は電鋳後のはく離膜の作用もする.金属電型の場合は,はく離膜をつける必要があり, 出典 森北出版「化学辞典(第2版)」化学辞典 第2版について 情報 |
