(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.

确定了优化思路后,对于此类问题的解决就简易很多。针对之前右下角铰链位置处的外观不良进行上述5个参数的逐一核实,并和得出的结论进行比对,发现其喷涂速度、喷涂距离还有一定的优化空间。因此,按照上述的思路进行参数适配性的修正,最终喷涂出的后盖MS密封胶外观效果也呈现了明显的优化和改善,波纹效果淡化了许多,如图所示。定量机,则冲洗总量设为160 mL,保证尽可能地把MS密封胶缸的胶水排空一次。
比如,对于一个80 mL定量机,在做手动冲洗的过程中,2x50 mL和1 x 100 mL有何区别?从数值上看,两者是一样的,但是2x50 mL的意思是每次排胶50 mL,排完后填充,再排50 mL,这种情况下,活塞每次都不会运行到MS密封胶缸的最底部,所以底部可能会出现干胶。而1x100 mL的运行情况是一次排100 mL的胶水,由于100 mL远远大于80 mL,所以一次将MS密封胶缸里的胶水完全排空掉,然后填充满,继续排出剩余的MS密封胶。1x100 mL的好处在于:一次能将MS密封胶缸里的胶水完全排放干净,最大程度上防止了胶水在MS密封胶缸内硬化的可能性。总的来讲,定量涂胶装置就是一个由多功能盒、泵体、填充阀、自动胶枪等组成的实现MS密封胶涂胶的重要工艺设备。定量涂胶装置性能的好坏关系着涂胶质量的优劣,直接影响到车辆NVH、淋雨密封等整车质量。因此保养维护好定量涂胶装置对于涂胶来说起着非常重要的作用,需要保养人员对其硬件结构及内部工作原理等十分熟悉,只有这样才能快速排查出问题所在。
在车身覆盖件上的密封胶,除了常见的密封性和防腐性能,其外观质量也是客户关注的重要一环。为了提高客户的感官体验,其MS密封胶外观质量也是汽车制造厂需要关注的重要内容。而在MS密封胶实际应用喷涂过程中,偶尔会出现一些表面波纹的不良效果,这在一定程度上会降低客户的感官体验,产生抱怨。
而表面波纹的产生因素往往比较复杂,因此本文在筛选和排除掉一些无关或低干扰因素为前提,筛选出5个关键参数,并通过控制变量的方法和设定合理的参数波动区间,放大影响效果,从而获得不同参数的变化所产生的外观影响趋势。最终获得了这5个关键参数的波动趋势和表面波纹的改善关系,从而获得优化方向。
在基于上述参数与波纹的改善关系后,对指定的问题区域参数进行适配性的修正,以实现精准可靠的外观质量优化。最终在不产生额外节拍、设备维护和工艺喷涂的潜在风险前提下,成功地优化了MS密封胶外观质量。http://www.sdyuantai.com/
