环保化学退铜剂

<p ">
<strong><span>1.</span></strong><strong><span> 环保化学退铜剂</span></strong><strong><span>特点</span></strong>
</p>
<p text-indent:32px;">
<span><span>（</span>1）</span><span>退镀剂不含易伤害铝和塑料基体的硝酸等强氧化剂，有利环境保护。特别适用于引线框架和铝腔体等上不合格镀铜层和镍层的退除。</span>
</p>
<p text-indent:32px;">
<span><span>（</span>2）</span><span>退镀后即可直接返镀或者经前处理后返镀。</span>
</p>
<p text-indent:32px;">
<span>（</span><span>3</span><span>）退镀速度快，一般情况</span><span>1-10</span><span>分钟。</span>
</p>
<p text-indent:32px;">
<span>（</span><span>4</span><span>）常温操作，节能环保。</span><span>   </span>

<strong><span>4. 环保化学退铜剂</span></strong><strong><span>溶液维护</span></strong>
</p>
<p text-indent:32px;">
<span><span>（</span>1）</span><span>退镀过程中，退镀速度会逐渐加快，溶液的温度会升高，当超过</span><span>35</span><span>℃</span><span>时，容易减短溶液寿命，应该通过控制操作频率、添加调整剂或者衡温方法来稳定溶液的温度</span><span>25</span><span>-</span><span>30</span><span>℃</span><span>。</span>
</p>
<p text-indent:32px;">
<span><span>（</span>2）</span><span>定期补充反应和带出减少的药液。</span><strong><span>定期分析铜离子浓度</span></strong><strong><span>,</span></strong><strong><span>若超出药液的管理范围（</span></strong><strong><span>45</span></strong><strong><span>克</span></strong><strong><span>/</span></strong><strong><span>升</span></strong><strong><span>），</span></strong><strong><span>请抽掉</span></strong><strong><span>1/3</span></strong><strong><span>～</span></strong><strong><span>1/2</span></strong><strong><span>旧液</span></strong><strong><span>（</span></strong><strong><span>溶液含铜和镍量饱和</span></strong><strong><span>析出时应该清掉晶体）</span></strong><strong><span>，</span></strong><strong><span>再添加</span></strong><strong><span>1/3~1/2</span></strong><strong><span>工作液继续退镀。</span></strong><span>例如：抽掉</span><span>1/2</span><span><span>旧液</span>100升后，应该先补充50升水，再补充50升退镀剂。当更换8-10次后，如果退镀速度很慢，溶液老化，</span><span>需更换槽液。</span>

<strong><span> </span></strong><strong><span>5. 环保化学退铜剂</span></strong><strong><span>注意事项</span></strong><strong><span> </span></strong>
</p>
<p text-indent:24px;">
<span>（</span><span>1</span><span>）</span><span> </span><span>退镀时应该有专人看管，注意温度变化。退镀完成后工件应立即提出进行水洗，以免时间过长造成工件基体腐蚀。</span>
</p>
<p ">
<span>（</span><span>2</span><span>）</span><span> </span><span>设备上的金属部分</span><span>,</span><span>应使用不锈钢筋</span><span>(SUS)</span><span>材质</span><span>(</span><span>不可使用铁、钛等金属</span><span>)</span>
</p>
<p ">
<span>机器设备的设置场所</span><span>,</span><span>需装设排气管道。药液槽内设置冷却器</span><span>,</span><span>以便容易控制液温。</span>
</p>
<p text-indent:24px;">
<span>（</span><span>3</span><span>）药品</span><span>储存</span><span>应置于暗冷场所</span><span>,</span><span>不可直接暴露在阳光下或高温、有火焰的地方。应注意空气的流通</span><span>,</span><span>避免放在密闭的空间内。</span>
</p>
<p text-indent:24px;">
<span>（</span><span>4</span><span>）</span><span>操作时需穿戴防护手套，切勿与皮肤直接接触。</span><span>接触皮肤时</span><span>,</span><span>马上用清水与肥皂清洗。不慎触及眼睛时</span><span>,</span><span>马上用清水冲洗</span><span>5</span><span>分钟</span><span>,</span><span>然后接受医师的诊察。</span><span> </span>
