<p>PURPOSE:To bond polyoxymethylene firmly to each other or to other material, by treating its surface with ammonia plasma before bonding. CONSTITUTION:In bonding polyoxymethylene to each other or to other material, its surface is treated with ammonia plasma for 5 minor longer before bonding. Said plasma must be a low-temperature plasma. A high-temperature plasma has excessively high energy that is causes high-molecular material to be broken during treatment, so that it is impossible to treat only the surface of the polymer. When a low-temperature plasma is used, only the surface can be treated under specified condition. A gas to be used in the generation of plasma must be ammonia gas and an effect of increasing the bond strength can be obtd. by using ammonia plasma.</p> |
