(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)严格控制硅烷改性聚氨酯密封胶的涂布方法

       ①连续生产前,员工须确认打胶机温度、皮带运行速度、出胶压力、铝条尺寸等相关参数符合加工工艺要求。

       ②调整铝条头部和尾部的出胶量,保证一条边头部的硅烷改性聚氨酯密封胶能够完全覆盖折弯的角部区域,并且与相邻的另一条边的尾部硅烷改性聚氨酯密封胶能连接上,且有一定的余量。

       ③员工用手扶铝框内侧(避免手指沾到硅烷改性聚氨酯密封胶),另一只手对四个角部位置(连接处)的硅烷改性聚氨酯密封胶稍加修饰,保证首尾的有效连接。然后用拇指将多余的硅烷改性聚氨酯密封胶压向铝条的背面并摊平。

       (2)严格控制铝条两侧硅烷改性聚氨酯密封胶的出胶量,既要保证两侧的出胶量足够(单边涂布量至少2.7g/m),即保证压合后的有效宽度(除膜宽度均匀一致并符合加工要求),又要保证两侧的出胶量基本一致。

       (3)打胶、上框、下片等工位的员工要做好首检、抽检,对整个加工过程形成封闭有效的控制。

       本文结合插角和折弯两种型式铝条在涂布硅烷改性聚氨酯密封胶工艺过程中存在的问题,提出了笔者的一些改善建议,目的是通过提高硅烷改性聚氨酯密封胶的有效密封性来控制中空玻璃的水气渗透率,最终保证中空玻璃的使用寿命。www.sdyuantai.com
