font-family: 宋体;">三、工艺流程</span></strong></p> <p><span quot;font-size: 12pt; font-family: 宋体;">  </span><span quot;font-size: 12pt; font-family: 宋体;">来件→脱脂→流动清水洗→流动清水洗→除锈→流动清水洗→流动清水洗→表调→磷化→流动清水洗→流动清水洗→热水烫干（80～90℃）→转下道工序</span></p> <p><strong><span quot;font-size: 12pt; font-family: 宋体;">四、槽液配制（以1000升为例）</span></strong></p> <ol> <li><span quot;font-size: 12pt; font-family: 宋体;">在磷化槽中加水800升，加本剂原液50㎏，促进剂7㎏，加水至1000升，搅拌均匀。</span></li> </ol> <p><strong><span quot;font-size: 12pt; font-family: 宋体;">五、使用及调整</span></strong></p> <p><span quot;font-size: 12pt; font-family: 宋体;">    将经除油、除锈的工件吊入表调槽浸泡0.5～1分钟取出，浸入磷化槽（不清洗）15～20分钟取出，经两道流动清水洗及一道热水烫干后转下道工序。</span></p> <p><span quot;font-size: 12pt; font-family: 宋体;">     在生产过程中定期检验槽液的总酸度与游离酸度，总酸度偏低时，加原液将其调整到工艺范围之内（很少有总酸度偏高的情况），游离酸度偏高时，加中和剂将其调整到工艺范围之内（很少有游离酸度偏低的情况）。同时还应经常测定和添加促进剂（促进剂点数的测定用氨基磺酸法），促进剂的添加应以少加、勤加为佳，切不可一次添加过多。本剂工作液沉渣较少，但仍须定期清除沉渣，根据生产量的大小，客户自行确定清除沉渣的周期和频次。</span></p> </div>
