不锈钢设备表面质量直接决定产品质量，如何提高其表面质量，一直是本领域面临的难题。不锈钢设备表面处理一般采用酸洗膏酸洗钝化和表面抛光处理：但是酸洗膏进行表面酸洗钝化，只能去除表面油污等，不锈钢表面颜色不一致，外观质量一致性差；而采用机械抛光，一般有手工抛光、机器抛光两种形式，但是存在打磨劳动强度大，时间长，效率低，成本高，而且一台设备抛光时间比制造时间长，小型设备内部焊缝无法抛光，且抛光纹路不一致。在此应用背景下，本发明的发明人欲提高不锈钢设备表面质量，提供了一种不锈钢表面处理工艺。
发明内容
本发明所解决的技术问题是提供一种不锈钢表面处理工艺，用以提高不锈钢设备的表面质量。
本发明不锈钢表面处理工艺，包括如下步骤：
A、预处理：先打磨不锈钢表面，去除焊渣及飞溅；然后用酸洗膏去除表面及焊缝的油污及氧化物；最后用清水去内外杂质
B、将不锈钢浸入酸洗钝化液，至表面形成银白色钝化膜，颜色均匀；
C、然后将不锈钢浸入中和液浸泡；
D、用清水浸泡去除表面附着溶液及杂质，干燥，即可。
本发明表面处理工艺适用于所有不锈钢设备、零部件的表面处理，只要是浸泡容器允许的情形下，均可以使用本发明处理工艺。
其中，本发明的关键在于步骤B使用的酸洗钝化液，它是由硝酸、氢氟酸、水组成，其体积百分比为：硝酸15-30％，氢氟酸1.5-7％，其余为水；其中硝酸按100％浓度计算，氢氟酸按100％浓度计算。
其中，步骤B浸泡的规定时间为60-180min，判断标准为不锈钢表面形成银白色钝化膜，颜色均匀即可。
其中，步骤C所述中和液为NaOH，浓度按质量分数计为10％-20％。
本发明表面处理工艺中是利用化学处理法，采用本发明酸洗钝化液整体浸泡不锈钢设备或零部件，可以在较短的时间内，在设备或零部件的内外表面形成一层银白色的钝化膜，达到表面颜色均匀，一致性好，然后再进行中和清洗，达到提高不锈钢设备或零部件内外表面质量的目的。本发明处理工艺处理所得设备或零部件表面质量有质的飞跃，另外设备或零部件内表面形成钝化膜能抗氧化和防腐蚀，提高设备或零部件的使用寿命。同时，本发明表面处理工艺与机械抛光相比，低成本，高效率，为公众提供了一种新型的不锈钢表面处理工艺。
