(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.

根据玻璃自身重量、用途和MS密封胶性能可以算出额定粘接面积s，按照设计意图测算止口周长z，施胶宽度尺寸a=slz,在理想状态下可以假设压合后MS密封胶两侧的圆弧为半圆状。转换关系如下:由图1可以出:c=D-E由图2和图3可以得出:abl2=ac+"rrc2/4由式(2)可以得出:b=2c+"rrc2/(2a)在a值不变的情况下，优化方案如下:

1)方案1。当b>2c+"rrc2/(2a)时，b值过大，玻璃的粘接面积大于车身饭金粘接面积，缺点是大于车身饭金粘接面积部分的胶能效过剩，造成浪费。并且由于胶体增大，固化时间延长，从而影响后道工序的正常生产，整体生产节拍推迟。

2)方案2。当b=2c+"rrc2/(2a)时，b值合适，玻璃粘接面积和车身饭金粘接面相等，两侧粘接力相等，不存在能效过剩，同时MS密封胶在玻璃和车身饭金之间的圆弧长度达到最大值，提高了MS密封胶的拉伸强度和剪切强度等。

3)方案3。当b<2c+"rrc2/(2a)时，b值过小，玻璃粘接面积小于车身饭金粘接面积。由于MS密封胶在玻璃粘接面积减少，对玻璃不能达到有效的粘接力，因此在车辆行驶过程中对驾驶员和乘客不能起到防护作用，具有安全隐患。

由以上分析可以得出:使用MS密封胶粘接的最佳效果是两面粘接的面积一样，推荐使用方案2。由于汽车成批量化生产，一些简单并重复的工作逐渐被机器所代替，机器人在施胶工序上的应用已经趋于成熟阶段，因其能够精准地控制施胶型状和用量而被推广使用，并得到市场认可。采用智能化生产已成为一种趋势。http://www.sdyuantai.com/
