(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.

耐久性、耐候性强。受紫外线、振动、摩擦、高低温影响小。耐化学腐蚀、耐油浸、耐细菌浸浊。长期使用不龟裂。不脱落于密封件能好:其有良好的防水性，水蒸汽透过率低粘结性好。同步变形能力强:聚疏丁基防水嵌缝密封胶伸长率高。模量低。有较强的弹性能随缝隙的变形协调同步移位,工性能好两组分混合后具有一定的流动可塑性，作业完一段时间后才固化、能充分填充或覆箫各种缝隙。无毒、无腐蚀、无污染，对环境讨人体不产生危害J尤其适用于饮水工程应用广泛聚硫丁基防水嵌缝密封胶能粘接金属、混凝土、琉璃等各种材料可用于道路、飞机跑,建筑物、水库、水厂池体、渠道等工程变形缝或裂缝的处治。在北京鸟巢土程、郑州机场土程、葛洲坝工程、常州污水厂一程、深圳南山水厂等项月中，双组分聚硫丁基防水嵌缝密封胶的应用，经受注各种条件的考验获得了满意效果二产的H-型非下垂明渠专用双组分聚硫高弹力建筑丁基防水嵌缝密封胶，该倒料采用聚硫原胶严格加工生产，含有大量的防紫外线照射因子，抗老化件能优越，粘接紧密，位移能力强:长期浸泡在水中不变形。不干裂不漏水无污染:产品出厂前应进行检验，按同一品种、同一类型的产品每为一批进行检验:产品包装、储存、标志应符合要求应有完整的出厂合格证，产品使用前应进行开桶检验、丁基防水嵌缝密封胶胶体应细腻光亮、无异物。无结皮现象，产品进场后应对质量抽样检验，执行其技术指标应符合表1要求。

使用开凿工具顺裂缝方向凿成深宽的+‘U”形槽沟剔除松动和不密实的w凝土，用空压机将槽沟缝隙内的浮尘与残渣吹除干净如果槽内潮湿.则用电吹风吹干或用喷灯供丁，保持缝槽内丁燥。确保胶沐与界面完全结合将按要求配制好的底涂料用毛均匀刷涂到缝槽的注胶基在挥发小时时间内及时注胶。底涂料挥发时l过长或过短都会影响到丁基防水嵌缝密封胶的粘结效果甲3聚硫密封材料双组分的配合比搅拌混合按配合比A(主i:I固化=1:1的比例将二者放人干燥清洁的容器内拌含叮用手动或电动搅拌的方式。但必须搅拌彻底，混合充分，双组分颜色达到完全均匀一致否则将影响两组分反应效果，以致直接影响到工程质量…两组分材料混合后的最佳使用期为3一4小时以内，所以丁基防水嵌缝密封胶在3一4小时内必须用完，过期不用要废弃过期胶料不能再和新混合的丁基防水嵌缝密封胶一起使用。否则会严重影响缝隙的密封质量。http://www.sdyuantai.com/
