(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.

(1)清洁混凝土缝壁，用钢丝刷刷净缝壁的泥土等杂物，并保持缝壁混凝土呈干燥状态。

(2)涂刷底涂液:设计要求使用底涂液的工程，或长期浸水部位的密封，需要涂底涂液涂刷在被粘表面上，干燥成膜。

(3)按规定的配合比，将两个组分混合均匀即可使用，不论机混还是手工混合，都应达到色泽均匀无色差。混合时应防止气泡混人，涂硅烷改性聚氨酯密封胶时应防止气泡混入，压实，填平密封处，并用刮刀将伸缩缝表面刮平抹光。

(4)揭除伸缩缝两侧胶带，这样一道整齐光洁的硅烷改性聚氨酯密封胶与闭孔泡沫板伸缩缝就完成了。硅烷改性聚氨酯密封胶与闭孔泡沫板水工伸缩缝应用和推广硅烷改性聚氨酯密封胶与闭孔泡沫板水工伸缩缝施工在上县琵芭山溢流坝工程中硅烷改性聚氨酯密封胶水工伸缩缝工程实施前期，经过充分的科学实验和论证，最后采用了装配式GB型复合橡胶止水，内嵌闭孔泡沫板和外用硅烷改性聚氨酯密封胶保护的复合止水形式，为一种较新型的止水结构。实践证明，该方案的设计与施工是科学合理的，其中，琵芭山溢流坝工程中已运行了3年多，所有伸缩缝均无漏水现象。该复合止水形式可作为其它类似工程伸缩缝止水结构设计与施工的参考，它为水利工程和其它工程提供了一种理想的嵌缝止水新材料。

本文主要对某汽车厂细密封喷涂机器人喷涂的硅烷改性聚氨酯密封胶表面波纹外观问题的产生原因进行梳理、探究和分析，并结合实际的喷涂情况筛选出了枪嘴设计、喷涂角度、喷涂速度、喷涂流量和喷涂距离5个可控参数，通过控制变量法设置了多组对照侧试，观察最终呈现状态的变化趋势后，针对其做出了优化和改进措施，以实现优化硅烷改性聚氨酯密封胶外观的目的。所得的结论可以给细密封喷涂机器人喷涂过程中一些常用参数设定提供参照思路，具有一定的工程应用价值。

随着越来越多的汽车制造厂对四门两盖的硅烷改性聚氨酯密封胶(PVC)外观质量关注度逐渐提高，细密封喷涂机器人的工艺应用也越来越广。在某汽车厂对细密封喷涂机器人的应用过程中发现，其喷涂烘烤完后的硅烷改性聚氨酯密封胶表面会出现清晰明显的波纹纹路，而这也会导致部分客户对其外观质量的不满。为了解决和优化这类问题，本文通过细致分析和对比各细密封喷涂机器人工艺应用和参数设定的区别，探究出其波纹纹路的形成原因和改进思路，以实现硅烷改性聚氨酯密封胶外观质量的优化目的。http://www.sdyuantai.com/
