Description

一种带消音器的汽车排气管
技术领域
本发明涉及一种带消音器的汽车排气管。
背景技术
排气管消音的原理是通过对排气气流气流折射、分散、膨胀等措施，使排气气流的流速降低。从而达到消音的目的。但是消音以后排气背压增高，影响废气排出的完全程度，会损失动力性和经济性。因此排气管的设计既要考虑到消音降噪，又要考虑动力性和经济性不要有太大的损失。除非十分必要，建议不要把排气噪音降得很低。
另外，这类排气管内的排气管主体的耐腐蚀性很差，使用寿命很短，经常需要更换。
发明内容
本发明要解决的技术问题是提供一种带消音器的汽车排气管。
为解决上述问题，本发明采用如下技术方案：

排气管主体通过涂装处理在其外表面形成防护膜，加工工艺为：
步骤①、将排气管放入处理剂中浸泡5分钟，处理剂由10份聚醋酸乙烯乳液、5份芳香族羟基酸、3份柠檬酸、0.5份黄酮甙、5份乙二醇和80份水混合制成；
步骤②、将排气管烘干，烘干温度为40℃；
步骤③、采用喷膜方法在排气管的表面涂装一层厚度为0.5μm的聚四氟乙烯薄膜；
步骤④、将排气管烘干，烘干温度为80℃；
步骤⑤、在排气管上的聚四氟乙烯薄膜的表面涂装底漆及面漆；
步骤⑥、将排气管烘干，烘干温度为70℃。
本发明结构简单，设计合理，通过过滤腔、回音腔、出气消音腔三个腔体相互配合设计分别实现了过滤、回音和消音工作，另外分别通过排气主管、出气主管和连通管进行相互连通，通过设置过滤层和消音器实现相关功能，具有高速高效、清洁安全、低成本、易维护，并且产品一致性得到保证，从而提高产品质量。另外，通过涂装处理排气管主体，使其耐腐蚀性能得到显著提升。
