电镀挂具对电镀质量的影响分析,烤漆房常识

文章发布: 发表时间: 2017-05-11 10:36:35

电镀挂具规划应当思考零件形状、镀液性质、出产方式(流水线手动线)、阴阳极之间的间隔及方位、装挂数量等。以确保零件在槽液内的电力线散布均匀,镀层厚度均匀共同,达到技术请求。
Electroplating planning should consider the shape of parts, plating properties, production methods (manual line line), and the range and interval between cathode and anode and loading quantity. In order to ensure that the parts in the groove of the power line is evenly distributed, uniform thickness of the film together to meet the technical requirements.
●挂具规划应当挑选合理的资料和绝缘资料。不镀部位应选用适宜的涂料和专用挂具绿勾胶,使挂具使用寿命延伸,坚持槽液清洗。
The hanger should choose reasonable planning materials and insulation materials. No parts should choose suitable plating coatings and special hanging green plastic hook, the hanger service life extension to bath cleaning.
●挂具规划时应当思考零件构造,以确保镀层厚度的均匀性,对槽液涣散能力差的,电流密度又高的,必要时应装置辅佐阳极及维护阴极。
The hanger planning should consider the parts of the structure, to ensure the uniformity of coating thickness, the bath and ability of the current density is too high, should help maintain the anode and cathode device when necessary.
●要有满足的导电截面积,确保挂具与零件触摸杰出,导电杰出。
The conductive cross-sectional area should meet, and ensure the hanger parts touch the outstanding, outstanding conductor.
●制造的挂具要装卸操作便利,出产效率高,镀液简单清洗掉,使用时零件不易坠落。
- to handling hanger manufacturing facilities, production of high efficiency, simple bath washed off, when the components are not easy to fall.
●重视镀件悬挂方位的挑选。悬挂方位与镀层质量有非常亲近的联系,要点需求防止以下四点。
Pay attention to the selection of plating parts. The orientation of the suspension is very close to the quality of the coating, and the following four points should be taken into account.
①尽可能防止装挂处的触摸印痕。在视点答应的条件下,利用孔穴是防止挂钩部位印痕的首选办法,这样做既有利悬挂牢度,又可防止装挂处的触摸印痕。
As far as possible to prevent the hanging of the touch imprint. In view of the agreed conditions, the preferred method is to prevent cavities in the hook position mark, it is beneficial to suspension fastness, touch imprint and can prevent the hanging.
②防止镀件的顶级凸出部位朝向阳极而遭到镀焦。镀件的顶级凸出部位离阳极过近会因电流过于会集而镀焦。
To prevent the top parts of the plating parts from being plated toward the anode. The top protruding parts plating from the anode is too close for current too gathered and the plating of coke.
③镀后需要抛光部位宜朝向阳极。抛光面朝向阳极有利于添加镀层厚度,留下被抛层,可以防止抛露底,取得更高的抛光面质量。
After polishing, the polishing part should be oriented to the anode. The polishing face to the anode to add the coating thickness, left left layer can prevent left open at the end, have a higher quality of the polished surface.
④防止镀件的凹入部位构成窝气。电镀时镀件的凹入面易集气;并不易散去,导致窝气,为此在确定装挂方位时要充沛估量到这一点。
The recessed part to prevent plating of air pocket. The concave surface plating plating of the gas gathering; not easily dispersed, resulting in the air pocket, hanging to determine the range to fully assess this point.
