(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.

       隨著工業(yè)的發(fā)展，丁基防水嵌縫膠高壓膠管的使用壓力日趨提高，為保證膠管與金屬接頭之間具有良好的密封性及使用耐久性，除正確設計金屬接頭結(jié)構(gòu)外，必須確定適宜的內(nèi)膠力學性能及形狀系數(shù)(即內(nèi)膠厚度、管頭長度)。實踐證明它對改進橡膠軟管密封性能具有重大意義本文就內(nèi)膠的力學性能與丁基防水嵌縫膠高壓膠管的質(zhì)量關(guān)系及配方設計等問題，提出精淺的看法，目的在于引起從事丁基防水嵌縫膠高壓膠管的研究，生產(chǎn)單位及工程技術(shù)人員的重視，使我國的液壓膠管的質(zhì)量得到提高，趕上或超過國際水平，文中的觀點難免不妥甚至錯誤，希廣大讀者給予指正。

       丁基防水嵌縫膠的剛性是判斷性能的主要標準之一剛性可理解為試樣的抗變形性，因此模量值是丁基防水嵌縫膠的剛性特征之一通常用一定伸長時的應力作模量，橡膠行業(yè)采用1}4%或3U40o定伸應力，即拉伸試驗中伸長1}0%或3 U4拓時，試樣單位面積所承受的拉力。以拉伸應力表示模量值，成為橡膠剛性的測試項目。在此應該強調(diào)這個模量與彈性模量(縱向彈性模量)不一樣。為避免引起混亂，采用定伸應力代替模量比較恰當，丁基防水嵌縫膠的定伸應力基本上與交聯(lián)鍵數(shù)，即與硫化度或交聯(lián)度成正比。網(wǎng)絡越密，交聯(lián)鍵間的分子鏈段越短，定伸應力也就越高。定伸應力與高分子的化學結(jié)構(gòu)及交聯(lián)鍵的性質(zhì)基本上沒有關(guān)系。定伸應力是瞬時模量，不是一個平衡模量，應該指出在低定伸條件下(如140腸或24000),能較好地反映交聯(lián)密度大小，所以國內(nèi)外許多廠家對模量值，定為測定100%定伸應力。性能好的內(nèi)膠定伸應力控制在l OMPa以上。http://hbxqtax.com/
