Description
技术领域
本发明涉及一种复底锅的硬质氧化工艺。
背景技术
目前,复底锅胚(即在锅胚的底面复合有复底片)在硬质氧化时,为了保护复底片不被氧化槽中的硫酸腐蚀,大多采用复底片贴膜或采用工装抽真空(例如CN115251696A)的方式,这种情况下,都需要投入很大的人力、物力和财力,对公司而言,是一种极大的浪费。就复底片贴膜的方式而言,人工加贴膜,其单锅成本在2.5元--3.5元(视贴膜的大小而定);就工装抽真空的方式,其单锅夹具成本在2.0元以上(视夹具的老化及使用频率而定,因为夹具即使补使用,也会出现老化现象,同时,如果复底氧化订单过少,投入的工装夹具导致的单锅成本就更高了)。并且,无论是复底片贴膜的方式还是工装抽真空的方式,才做起来都非常复杂,对操作工的操作熟练程度有很高的要求。
发明内容
为了克服现有复底锅的硬质氧化工艺中的上述不足,本发明提供一种成本低、操作简单的复底锅的硬质氧化工艺。
本发明解决其技术问题的技术方案是:一种复底锅的硬质氧化工艺,包括下列步骤:
S1:化学药液覆涂复底片:通过喷枪将化学药液雾化涂覆在需被保护的复底片表面;
所述的化学药液涂料由下列组分组成:
纳米硅溶胶 7-15质量份
正丁醇 40-60质量份
聚苯甲基甲基硅氧烷 3-8质量份
纯净水 30-50质量份;
S2:化学药液表干:用烘干炉,将覆涂的化学药液在80℃下烘干2min进行固化;
S3:外打砂:用百洁轮,将金属锅胚外表面进行打砂处理;
S4:硬质氧化:将复底锅胚整体进行硬质氧化处理。
优选的,所述的金属锅胚为铝质。
本发明的有益效果在于:本发明采用水性的化学溶液进行喷涂复底片处理,喷涂膜厚只有2-3μm即可。该化学溶液经过固化后,有很强的封闭性及耐酸耐碱性能,能极大满足硬质氧化条件下的强酸及强碱溶液腐蚀。由于其所用化学原材料都是最常规的,且用量极少,单锅成本在0.3元-0.8元,极大降低公司的硬质氧化工艺投入,且操作起来也非常简单。
