<span><span>三</span></span><strong><span><span>、生产维护</span></span></strong>
</p>
<p>
<span>1、</span><span><span>生产过程中铜离子控制在</span></span><span>8</span><span>-</span><span>12</span><span><span>克</span>/<span>升，铜离子含量可采用化学分析来测定，并通过    调节石墨阳极与电解铜的阳极面积比例来进行管控。</span></span>
</p>
<p>
<span>2、</span><span>RC-666A<span>环保镀铜开缸剂只在新开槽时使用，日常生产只需添加</span><span>RC-666B</span><span>环保镀铜补充剂。</span></span>
</p>
<p>
<span>3、</span><span>RC-666B<span>环保镀铜补充剂可通过分析补充，。</span></span>
</p>
<p>
<span>4、</span><span>pH<span>值控制：调高</span><span>pH</span><span>用</span><span>10%</span><span>氢氧化钾溶液，调低</span><span>pH</span><span>用酒石酸。</span></span>
</p>
<p>
<span>5、</span><span><span>铜离子不足时，镀层高区粗糙，沉积速度下降，可通过提高电解铜阳极面积比例来提高铜离子浓度。</span></span>
</p>
<p>
<span>6、</span><span><span>铜离子过量时，镀层低区粗糙，可适量补充</span>RC-666B<span>环保镀铜补充剂。</span></span>
</p>
<p>
<span>7、</span><span>RC-666B<span>不足时，镀层低区粗糙，可适量补充</span><span>RC-666B</span><span>环保镀铜补充剂。</span></span>
</p>
<p>
<span>8、</span><span>RC-666B<span>过量时，沉积速度下降，可适量提高铜离子浓度。</span></span>
</p>
<p>
<span>9、</span><span><span>若因前序工序或原材料带入的异金属或有机物杂质，造成镀层发暗发灰，可以用活性炭处理，。</span></span>
</p>
<p>
<span> </span>
</p>
<p>
<span>四、</span><strong><span><span>储存</span></span></strong>
</p>
<p>
<span>   <span>存放于阴凉干燥处，不得与强酸性物质混放；高温下或遇强酸性物质会发生反应，生成有毒害物质。</span></span>
</p>
<p>
<strong><span> </span></strong>
</p>
<p>
<span>五、</span><strong><span><span>废水处理</span></span></strong>
</p>
<p>
<span>1、</span><span><span>废水排放按常规破络合剂方法进行处理，详细方案请咨询本公司技术部。</span></span>
</p>
<p>
<span>2、</span><span><span>未经处理废水不得与强酸性物质混排，否则会发生化学反应生成有毒害物质。</span></span>
</p>
<p>
<span>3、</span><span><span>泄露应急处理：发生废水泄露时，用适量氯酸钙或硫酸亚铁充分反应后排放至废水池。</span></span>
</p>
<p>
<span> </span>
</p>
<p>
<span><span>注：</span>RC-666A<span>、</span><span>RC-666B</span><span>存放期间产生分层、沉淀或变色，属正常现象，摇匀后使用，不影响效果。</span></span>
