Description

一种铁制护栏管镀锌生产工艺
技术领域
本发明涉及一种铁制护栏管镀锌生产工艺，应用于铁制护栏加工技术领域。
背景技术
护栏主要用于住宅、公路、商业区、公共场所等场合中对人身安全及设备设施的保护与防护，由于护栏应用于生活中的各个方面，市场上生产护栏的厂家越来越多，为节约材料成本，许多厂家采用铁管作为原材料，但铁管在长期使用后，容易被空气氧化，易生锈，使用寿命不长。
发明内容
为解决上述的问题，本发明公开了一种铁制护栏管镀锌生产工艺，由下列步骤组成：
1）检查铁管是否具备镀锌的工艺孔；
2）脱脂：将铁管置于清水中，并加入水基金属脱脂清洗剂对铁管表面进行脱脂处理，铁管需被清水完全浸润；
3）酸洗：取出工件，将其置于20%HCL溶液中进行酸洗，升温至20~45℃，同时加入六次甲基四胺，加入量为1~2.5g/L；
4）水洗：取出工件，用水将铁管表面的酸水及其它附着物清洗干净；
5）将铁管置于助镀剂浸泡5~10min；
6）烘干：从助镀剂中取出铁管，将铁管置于干燥室中烘干，预热温度为120~180℃；
7）镀锌：将预热后的铁管浸泡于450~470℃的锌液中1~1.5min,获得一层镀锌层 ；
8）钝化：将镀锌后铁管置于铬酸钾溶液中浸泡5分钟后，取出干燥，然后采用温水缓慢冷却；
9）检验：对铁管进行检验，并逐级分装。
步骤5)中助镀剂溶液中氯化铵占20~25%，氯化锌占2~3%，甘油0.1~0.5%，余量为水。
采用本技术方案，本发明的有益效果是：在铁管表面镀锌，能够大大提高铁制护栏的抗氧化能力，不易生锈，使用寿命更长。
