Description

一种特氟龙喷涂方法
技术领域
本发明属于材料处理技术领域，具体涉及一种特氟龙喷涂方法。
背景技术
特氟龙涂料是一种高性能涂料，通过结合耐热性、化学惰性和优异的绝缘稳定性及低摩擦性使其具有其他涂料无法抗衡的综合优势。它的灵活性使得它能用于几乎所有形状和大小的产品上。
特氟龙喷涂的方法是采用一种粉体涂层加工的干式方式，使用的涂层材料为及其细小的固体颗粒形态，加工时将微粉状涂层颗粒附着于工件表面，随后覆盖的微粉在烘炉中熔融。
因此，本发明提供一种更为牢固的特氟龙喷涂方法。
发明内容
为解决现有技术存在的缺陷，本发明提供一种特氟龙喷涂方法。
为了解决上述技术问题，本发明提供了如下的技术方案：
本发明提供一种特氟龙喷涂方法，包括以下步骤：
S1、去除工件表面的油脂，使得工件表层获得足够的表面附着力；
S2、遮蔽，遮蔽工件不需要喷涂的面；
S3、喷砂处理，采用喷砂处理的方式清洁工件表面使其毛躁；
S4、喷涂底漆，采用喷涂底漆方式喷涂工件表面，改善工件表面的结合能力；
S5、PFA处理，采用压缩动气将PFA粉状颗粒从捕集器中吹出，PFA粉状颗粒通过喷嘴中带静电的一段管路使其带电，喷枪和工件之间形成带电区域，使得PFA粉状颗粒受工件吸引附着到工件表面上去；完成后取出工件，待其冷却；
S6、PTFE处理，采用压缩动气将PTFE粉状颗粒从捕集器中吹出，PTFE粉状颗粒通过喷嘴中带静电的一段管路使其带电，喷枪和工件之间形成带电区域，PTFE粉状颗粒受工件吸引附着到工件表面上去；完成后取出工件，待其冷却，去除遮蔽。
作为本发明的一种优选技术方案，步骤S1中去除工件表面的油脂，使用有机溶剂溶解油脂并加温至400℃使其挥发。
作为本发明的一种优选技术方案，步骤S2中采用聚酰亚胺材质的耐高温胶带遮蔽工件不需要喷涂的面。
作为本发明的一种优选技术方案，步骤S6中PFA粉料熔融时，温度在300-400℃，根据工件大小调节烘烤时间。
本发明的有益效果是：本发明采用PFA与PTFE结合的方式，使得特氟龙表面更为牢固，触感更光滑，表面质量更高，耐腐蚀能力更强。
