铝型材的种类和它的表面处理工艺

铝合金窗资讯 2022年7月31日 11:02

铝型材的表面处理可主要分为五种：一：氟碳喷涂。二：粉末喷涂。三：阴阳极氧化。四：电泳。五：电镀。有相似之处。但也略有不同。

氟碳喷涂工艺引入氟元素，电负性大，使用氟碳树脂具有良好的优越性。例如：耐热、耐腐、耐气候性等优良特性。粉末喷涂工艺较为简单，其生产过程中可以自动提高精度，技术参数可以实现微电脑控制，使其降低操作难度，同时减少辅助设施，极大的缩减了费用。(阴)阳极氧化处理方式，首先脱脂，然后使用自来水清洗干净，使用酸进行腐蚀。快速整平消除表面痕迹并要进行着色等等，诸多循环工序。电泳分为阴阳极，具体可根据基体材料种类或目的来确定使用类型。阴极电泳工艺采取聚氨酯涂料对其表面进行涂抹覆盖等处理。阳极电泳工艺中可使用丙烯酸涂料进行涂抹和覆盖。最后使分子变得均匀，将乳化效果发挥到最好。

电泳型工艺具有水溶性好、涂装效率高、涂膜厚度均匀、附着力强、质量好、生产效率高、投资费用高等特点。电镀工艺首先使用酸浸，去除表面氧化层。用具有酸性清洁剂进行清洁。其次进行微微腐蚀，将表面处理干净，水洗然后使用硫酸铜进行镀铜。它可以提升产品的美化值，提升产品的附加值。促进基体防护。增加产品寿命，节约资源。具有特殊的表面性质。

铝型材提高产品导电性、可焊接性、使非金属材料金属化，从而使产品更加耐磨。
