文章发布: 发表时间: 2016-05-05 14:34:35

喷塑加工线通常选用水帘喷漆室、水旋喷漆室、干式喷漆室、卧式喷漆室等对工件进行喷涂。喷塑涂装线通常选用静电喷涂方式对工件进行喷涂,喷塑烤房滚球体育的首要设备由喷粉室、静电喷粉设备及喷枪、粉末收回设备等构成。现首要以喷漆涂装线中的水帘喷漆室为例进行概述和剖析。这种水帘喷漆室简略有用,现在在喷漆涂装线中使用较多。

Pensu processing line is usually used water curtain spray paint room, water whirling spraying chamber, dry paint room, horizontal spray paint room on the workpiece spray. Spray coating line usually choose electrostatic spraying method of workpiece spray, spray baking room is the first equipment by the powder room, electrostatic powder spraying equipment and spraying, powder recovery equipment. The first to spray curtain coating line in the spray chamber as an example of an overview and analysis. The water curtain spray booth simple useful, now used more in the painting line.
