(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.

Information

    (1)MS密封胶出供箱后黏性维持时间一般为3  min,所以在最短时间内完成粘合可获得最佳粘接效果。否则,随时间的延长实体温度下降,影响粘接效果。

    (2)经验得知,MS密封胶的最佳粘合温度为48一54℃,低于45℃,钻性明显降低;高于65℃,可能造成未枯合完成胶层已矢去翁性。同时,压合后徐胶边缘线易产生拉丝,材料间吻合度不好,或因该处张力较大形成脱胶及假性粘接。

    (3)最后一道烘箱出口处最好设置保温罩,以免温度下降太快,影响粘接牢度。

    加压

    (1)加压的时间长短和压力高低依鞋型、材质而定。张力大的鞋型,应延长压合时间,一般在2. 5-3. 0 MPa压力下压合10一12 s。

    (2)压合时,使用三合一强式压合机,一次压合完成。因为多次压合产生的剪切力会破坏已粘合的粘接面。

    整理

    (1)整理时应避免整理用的溶剂渗人粘接面,从而降低粘接强度。

    (2)如设置有再加工成型工序,应放置24 h,待MS密封胶反应完成后再进行,以免热活化时造成脱胶。
