(Summary description)Customized SILICONE STRUCTURAL SEALANT from China manufacturer refers to the adhesive with high strength, can bear large load, aging resistance, fatigue resistance and corrosion resistance, and has stable performance within the expected life. It is suitable for bearing the bonding of strong structural parts. Non structural adhesive has low strength and poor durability. It can only be used for bonding, sealing and fixing of ordinary and temporary properties, and cannot be used for structural adhesive bonding. NEUTRAL SILICONE WETHERPROOF SEALANT from China manufacturer is a structural adhesive with waterproof function. Silicone glue refers to the adhesive based on silicone rubber. According to different functions, it can be divided into structural adhesive, potting adhesive, sealant, thermal conductive adhesive, flame retardant adhesive and so on.

在涂装工艺过程中，MS密封胶作为车身密封和防腐重要的一环，对车身的密封和腐蚀性能提升起着重要的作用，并且针对一些覆盖件的客户可见区域，其外观呈现出的效果也是需要重点关注的内容。

为常见的四门两盖焊缝MS密封胶密封示意，MS密封胶需要喷涂在装焊饭材折边焊缝位置，对折边焊缝密封严密，以保证车身的密封功能和腐蚀性能。某汽车制造厂的某车型由于该区域属于客户可见区域，因此MS密封胶喷涂的表面外观效果也是需要重点关注和评估的。从外观层面而言，MS密封胶应具备胶条整体平顺、过渡平滑、表面平整均匀等特点。

某汽车厂在对车身后盖实施细密封喷涂机器人工艺喷涂过程中发现，其喷涂出的MS密封胶表面会出现明显的波纹效果，当客户打开后盖的时候，在一定程度上影响客户的体验。因此消除掉波纹效果，保证MS密封胶的良好外观质量至关重要。

为基于某汽车厂某车型的后备厢盖密封胶喷涂效果，可以清晰地看见喷涂完后的MS密封胶表面有着明显的波纹效果，尽管其对于折边的焊缝覆盖良好，密封和防腐功能得到保证，但这种明显的波纹效果会较大程度上影响客户的观感体验。此外，这类表面波纹在烘烤后或经过后续的色漆、清漆工艺之后也无法淡化和消除。因此解决和优化这类问题，必须从根源上去分析和遏制。本文主要通过差异对比、关键参数识别和关键参数的控制来锁定该问题产生的核心原因，并确定后续的优化和调整思路。

为了确定后续的优化思路，首先需要确认的就是波纹问题产生的潜在因素，才能对症下药。通过观察整圈后盖MS密封胶的外观，发现该波纹效果主要集中在右侧铰链附近的拐角位置，而在其他平顺笔直区域的焊缝位置，其表面波纹的效果明显淡化，基于此可以初步判定其设备能力不存在明显的缺陷，具备喷涂无明显波纹MS密封胶的能力。

排除掉设备能力的影响后，那么需要关注的就是覆盖件本身的焊缝设计、制造及程序设定相关因素。而通过对比左右侧铰链的波纹形态及焊缝状态时发现，其自车身的焊缝结构基本对称一致，但其呈现的波纹效果也不完全相同。http://www.sdyuantai.com/
