针对家电产品的五金喷涂工件在生产及使用过程中所遇到的生锈爆粉问题,通过对常规酸性硅烷与免水洗碱性硅烷的成膜原理分析,两种工艺处理后的工件防锈能力试验及实践比对,结果表明在碱性硅烷前处理环境下,工件防锈能力比酸性硅烷环境下大大提升,更能解决工件易生锈爆粉问题。同时免水洗碱性硅烷工艺可在硅烷后取消水洗工序,前处理工序由9道减少至6道,节能降耗。故使用免水洗碱性硅烷可帮助企业优化喷涂工艺及成本改善。

Aiming at the problem of rusting and peeling in household appliances sprayed metal parts during production and use,through the analysis of the film forming principle of conventional acidic silane and water-free alkaline silane,the anti-rust ability test and practice comparison of the workpieces treated by the two processes.The results show that in the alkaline silane pretreatment environment,the anti-rust ability of the workpiece was greatly improved compared with that in the acidic silane environment,which can better solve the problem of easy rust and powder explosion of the workpiece.At the same time,the water-free alkaline silane process can spare the washing process after silane,and the workpiece pre-treatment process is reduced from 9 processes to 6 processes,saving energy and reducing consumption.Therefore,the use of water-free alkaline silane can help enterprises optimize the spraying process and improve the cost.
