(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.

提出了LED产生硫化的原因和危害，并对MS密封胶中有可能产生存在硫元素的原材料的生产工艺进行分析，提出了避免采用存在硫元素的原材料使用时的注意事项。

LED球泡灯外壳tll:接ofMS密封胶主要是应用于铝或陶瓷热从座。泡壳之问的粘接密封.一般足采用自色的MS密封胶川行粘接密封如图1是LED球泡灯的基本结构图:3MS密封胶的原理和组成成分MS密封胶是将所有必要的成分一起装入一个密封容器(软侣或胶瓶)中的类产品，使用时从密闭容器中挤出，接触空气交11关成弹性体，(价反应性几七础聚合物，构式为;般由以下成分组成经羚笨封端的聚有机基硅氧烷，其结原料工艺及含硫分析有机硅烷一类合物和有机侧烷交联剂都是由有机氯硅烷为要原料经过水解合成，以砖氧)键为l一链，硅原百接连接有机基的有机一无机化合物。于合成J_艺经过多逆的化学分离和提纯，且鼓初的原料l几要是含碳为99.99%硅粉和甲醇为原料，基本没有硫儿索的存。

作为有扫 }砖密封胶自勺补强填料一般为自炭黑和碳酸钙，其中碳酸钙可分为:轻质碳酸钙和重质碳酸钙:自炭黑般为气相法和沉淀法轻质碳酸钙简称轻钙，是将石灰不:等原料锻烧生成石灰和一氧化碳，再加水消化石灰生成石灰乳，然后再通入1氧化碳碳化石灰乳生成碳酸钙沉淀，鼓后经脱水，干燥和粉碎而制得由于轻钙是经过多道的化学合成和提炼1.艺生产出来的碳酸钙，笨本不会有硫元素的产生爪质碳酸钙(俗称工钙)ti用机械方法(宙蒙磨或其它高爪磨)直接粉碎天然的方解石、石灰石、自、n贝壳等经再经分级、分使用轻质碳酸钙和气相法白炭黑作为补填料，氯化法钦白粉做为增白剂，有机锡化合物作为催化剂生产的MS密封胶作为LED球泡灯外壳粘接用密封剂，可以避免硫及硫化物的存在，很好的控制了由于粘接用MS密封胶所带来的硫元素导致LED球泡灯的硫化现象，很好的延氏了LED球泡灯的使用寿命。http://www.sdyuantai.com/
