名称:水性散热电泳漆,散热涂料 Water-b…
详细介绍:

散热片是一种给电器中的易发热电子元件散热的装置,多由铝合金,黄铜或青铜做成板状,片状,多片状等,如电脑中CPU中央处理器要使用相当大的散热片,电视机中电源管,行管,功放器中的功放管都要使用散热片。一般散热片在使用中要在电子元件与散热片接触面涂上一层导热硅脂,使元器件发出的热量更有效地传导到散热片上,再经散热片散发到周围空气中去。
本公司开发出一种应用于散热片材料的纳米水性散热电泳涂料,该涂料由丙烯酸聚氨酯体系组成,应用广泛, 分为阴极散热电泳涂料和阳极散热电泳涂料。

Heat sink is a device to heat the electronic components in the heat-emitting devices, mostly made of aluminum, brass or bronze plate, flake, multi-sheet, such as the computer CPU central processor to use a considerable The heat sink, the TV in the power tube, the tube, power amplifier tube amplifier must use the heat sink. General heat sink in the use of electronic components and heatsink contact surface coated with a layer of thermal grease, the components of the heat emitted more effectively conducted to the heat sink, and then through the heat sink to the surrounding air to go.
The company has developed a heat sink material nano-aqueous thermal electrophoretic coating, the paint by the acrylic polyurethane system, widely used, divided into cathodic cooling electrophoresis coating and anode cooling electrophoresis coating.
