S1.除油:使用除油液对将要进行表面处理的耐酸钢工件进行除油,所述除油液由重量份配比为8-12:1的水和过氧化氢混合而成;
S2.喷砂:对除油后的耐酸钢工件进行喷砂,所用喷砂原料为精炼石英石,所述精炼石英石的粒径为0.05-0.1mm;
S3.抛丸:使用抛丸机对喷砂后的耐酸钢工件进行抛丸,所用耗材为粒径为0.03-0.05mm的钢砂;
S4.冲洗:将抛丸后的耐酸钢工件进行清水冲洗;
S5.抛光:使用角磨机将耐酸钢工件进行抛光;
S6.钝化:使用钝化剂对抛光后的耐酸钢工件进行钝化,所述钝化剂由重量份配比为3:2的铬酸镁和铬酸钠溶于100份的水中混合而成;
S7.二次冲洗:将钝化后的耐酸钢工件进行二次冲洗,所用冲洗液为5%的过氧化氢溶液;
S8.甩干:使用甩干机将冲洗好的耐酸钢工件甩干,即完成其表面处理。
优选地,所述步骤S2.喷砂中使用的喷砂管的材料为充油丁苯橡胶,其耐磨系数为62-75mm3
本发明的仅通过简单的工序即可有效地对耐酸钢工件进行表面处理,且处理过程中的能耗低,耗材可回收再利用,因此成本较低。
