style="text-indent:24.0000pt;text-align:justify;"> <span>在電泳涂裝</span><span>大生產</span><span>中，</span><span>老手們都熟知</span><span>槽液溫度</span><span>也</span><span>是</span><span>一個很</span><span>重要的控制參數</span><span>。</span><span>槽液溫度</span><span>的高低，會</span><span>直接關系</span><span>到</span><span>電泳漆</span><span>槽</span><span>液的穩定性、漆</span><span>膜</span><span>質量</span><span>、返工率</span><span>和生產效率</span><span>，進而影響到經濟效益</span><span>。</span><span>但溫度絕不僅限于槽液溫度，氣溫的影響也很大，這點往往會被忽略。今天，<a href="http://www.pekpet.com/dianyongqizixun/19-988.html" target="_blank">電泳漆廠家</a></span><span>飛揚小編就這個事情再深入聊聊，有利于新手的學習，也可有助于老師傅認識的加深。</span> </p> <p class="MsoNormal" align="justify" style="text-indent:24.0000pt;text-align:justify;"> <span>先談談<a href="http://www.pekpet.com/dianyongqizixun/19-988.html" target="_blank">槽液溫度</a>的影響</span><span>。</span> </p> <p class="MsoNormal" align="justify" style="text-indent:24.0000pt;text-align:justify;"> <span>電泳漆槽液溫度</span><span>上升</span><span>時</span><span>，</span><span>會伴隨著如下現象的產生：</span><span>涂料粒子布郎運動加</span><span>快</span><span>，漆液粘度</span><span>下</span><span>降，</span><span>電</span><span>沉積量增加，漆液電阻下降，泳透力</span><span>下降</span><span>，電</span><span>泳電</span><span>流加大，溶劑揮發</span><span>加</span><span>快，漆液穩定</span><span>性下降等。槽液溫度若</span><span>嚴重</span><span>超高則</span><span>會導致整槽電泳漆</span><span>液</span><span>報廢</span><span>！</span> </p> <p class="MsoNormal" align="justify" style="text-indent:24.0000pt;text-align:justify;"> <span>相應地，隨著</span><span>電泳漆槽液溫度</span><span>上升或偏高，電泳漆膜方面則</span><span>會</span><span>表現為：漆</span><span>膜</span><span>膜厚增加</span>、漆膜桔皮現象趨于明顯或嚴重、顆?，F象等。 </p> <p class="MsoNormal" align="justify" style="text-indent:24.0000pt;text-align:justify;"> <span>電泳漆槽液溫度過</span><span>低時，有利于漆液的穩定性維護。但漆液粘度會加大，電</span><span>沉積量</span><span>減小，易產生漆膜偏薄、光澤度低、遮蓋力欠佳，</span><span>工件</span><span>內腔</span><span>就上漆</span><span>少</span><span>，還可能會出現漆膜粗糙、無光等漆膜問題</span><span>。</span> </p> <p class="MsoNormal" align="justify" style="text-indent:24.0000pt;text-align:justify;"> <span>所以，通過冷暖機將槽液溫度嚴格控制在指標范圍內，是很重要的。這點大家也都明白，但<a href="http://www.pekpet.com/dianyongqizixun/19-988.html" target="_blank">氣溫的影響</a>，則往往易被忽視。有一定經驗的一線管理人員會有這么一個發現：槽液參數、工藝參數、電泳產品都沒什么變，冬夏兩季電泳生產，質量總是會有所不同。冬天生產往往會易出現漆膜偏薄、縮孔或針孔等很多異?，F象。夏天則易偏厚，或濾袋更換頻率增加等。這就是不同季節氣溫影響所致。</span> </p> <p class="MsoNormal" align="justify" style="text-indent:24.0000pt;text-align:justify;"> <span>冬天會增加脫脂的難度，電泳膜厚受影響等您都懂，但您是否考慮過水洗的效果也在下降呢？</span> </p> <p class="MsoNormal" align="justify" style="text-indent:24.0000pt;text-align:justify;"> <span>冬天嚴寒時放在倉庫里的電泳漆會發生冰凍，但您是否又會想過夏季高溫時候，放在倉庫里的電泳漆又會不會發生</span><span>“中暑”呢？</span> </p> <p class="MsoNormal" align="justify" style="text-indent:24.0000pt;text-align:justify;"> <span>所以，電泳漆在涂裝生產中的應用，很多時候跟人對身體的保健道理是相通的，需根據季節環境的變化而相應地變化，相應的調整工藝參數或管理對策，方可保障良好的電泳品質。</span> </p> <p class="MsoNormal" align="justify"
