(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.

從可以看出，相同寬度的條件下，組試片最大強度和最大強度伸長率隨厚度增加而下降;與組和組相組和組的寬度尺寸較大，最大強度和最大強度伸長率隨厚度增加下降非常明顯，這說明該寬口厚尺寸不合適，也不符合丁基防水嵌縫膠膠縫設(shè)計要求口在組和組中，寬度不變時，丁基防水嵌縫膠試片最大強度隨厚度變化有一些變化，但變化不明顯，其中組極差最大，為但寬度不變時，丁基防水嵌縫膠試片最大強度伸長率隨厚度變化較大，其中組極差最大為a。寬厚比變化對丁基防水嵌縫膠性能的影響；取養(yǎng)護%的試片，將同尺寸同條件下的試片測試結(jié)果取平均值，處理結(jié)果如表所示。

比較了同一寬厚比口不同厚度的試片的最大強度和最大強度伸長率口M組和N倒組中，當厚度大于1VIP時，丁基防水嵌縫膠最大強度和最大強度伸長率隨厚度增大下降明顯，因此厚度大于NP是不合適的，也不符合丁基防水嵌縫膠膠縫尺寸設(shè)計要求。PrP不同養(yǎng)護時間對丁基防水嵌縫膠拉伸粘結(jié)性的影響將同尺寸同條件下的試片測試結(jié)果取平均值，處理結(jié)果如表。

從可以看出1VPfl1VPIc組試片養(yǎng)護P1Vl后最大強度趨于穩(wěn)定，但最大強度伸長率隨養(yǎng)護時間的延長略有下降口可以認為，該尺寸條件下丁基防水嵌縫膠最短養(yǎng)護時間應為48。既有丁基防水嵌縫膠再粘結(jié)試片拉伸粘結(jié)性將現(xiàn)場施工已養(yǎng)護好的硅酮丁基防水嵌縫膠割膠后，制成型試片，將同尺寸同條件下的試片測試結(jié)果取平均值，測試結(jié)果如表/所示。http://pingjia100.com/
