Description

一种大批量小规格金属构件表面防腐处理工艺
技术领域
本发明涉及金属构件表面防腐处理技术领域，特别是一种大批量小规格金属构件表面防腐处理工艺。
背景技术
作为桥梁、高铁等各种户外建筑，其中一些螺母、螺栓等小规格金属构件承担着连接和支撑功能，对于户外建筑的安全稳定和长期使用起着十分重要的作用。小规格金属构件，由于长期面对冰冻和高温、严寒、酸雨、湿度以及空气氧化等复杂因素，特别容易发生腐蚀进而破坏建筑整体的安全和寿命。
传统的小规格金属构件表面防腐处理，一般都采用电镀锌或热浸锌工艺方法，这种方法由于镀层不均匀以及锌渣堆积等因素，不仅影响金属构件表面尺寸精确度，而且表面粗糙，防渗透能力差，抗腐蚀耐久时间短，不能和百年建筑达到同样使用寿命，另外对于大批量小规格螺母、螺栓等金属构件，电镀锌或热浸锌工艺方法生产效率低下，也容易造成对环境的污染。
发明内容
为了克服现有技术工艺的不足，本发明提供了一种大批量小规格金属构件表面防腐处理工艺。
本发明解决其技术问题所采用的技术方案是：
一种大批量小规格金属构件表面防腐处理工艺，包括以下步骤：
步骤一、将需要进行表面处理的大批量小规格金属构件经过除油清洗后分批装进达克罗浸涂、甩干一体化集装桶内，所述金属构件总体积以不超过所述集装桶容积五分之四为宜，然后盖紧所述集装桶上盖。所述集装桶，上部设有吊钩，底部还设有旋转槽，其侧壁、底部和上盖均设计成网格，便于达克罗涂液渗入和排出。
步骤二、将步骤一中所述的集装桶完全淹没和浸泡于达克罗涂液中，让所述达克罗涂液完全均匀涂覆在所述金属构件表面，浸泡时间大约一小时左右。所述达克罗涂液由极细的片状锌、铝及三价铬酸盐等成分构成，是一种取代电镀锌和渗锌等传统防腐处理的一种最新工艺技术。
步骤三、将步骤二中所述的集装桶吊起并将底部旋转槽安装在密闭的甩干装置底座，启动甩干装置，经过5分钟左右高速离心旋转，将所述金属构件表面达克罗涂液甩干。
步骤四、将步骤三中经高速离心甩干的所述集装桶内的所述金属构件，均匀地倾倒在循环网带上，启动所述循环网带，所述循环网带先经过烘烤舱，经300度～320度烘烤约一小时后出舱，再通过所述循环网带经过风冷吹干舱吹冷风干后收集在成品筐内，然后分类、检验、包装、入库。
经达克罗表面防腐处理的金属工件，不仅具有优美的亚光银色外观，而且防腐层极为致密和坚硬，耐腐蚀性能优越，耐腐蚀时间长久。
与现有技术工艺相比较，本发明的有益效果是：
本发明所提供的一种大批量小规格金属构件表面防腐处理工艺，通过现代化达克罗生产线，将大批量小规格金属构件通过集装桶实现批量化涂覆、甩干、烘烤和风冷吹干在线一体化，不仅严格保证了作业环境优良以及所述金属构件表面防腐性能优越，而且还实现了大批量不同规格金属构件集约化处理，显著提高了生产效率，降低了生产成本。
