(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.

       丁基防水嵌縫膠被汽車制造廠商廣泛地用來取代熔焊接,其粘接對象包括復合塑料以及金屬材料。它不僅能粘接各種結(jié)構(gòu)元件,而且有密封功能。其優(yōu)點是傳統(tǒng)的機械鉚接、焊接工藝所不具備的。例如聚氨酷泡沫產(chǎn)品可用于車身結(jié)構(gòu)的降噪、減震。車身構(gòu)件中的一些中空結(jié)構(gòu),往往會引起空氣的共鳴、從而產(chǎn)生噪聲。在這些中空結(jié)構(gòu)中填充以緊密的泡沫,就會使上述問題得到解決,這種泡沫有高密度和低密度之分。低密度的泡沫可用來注填汽車構(gòu)件中的一些坑洞。當?shù)兔芏鹊呐菽⑷说娇佣粗,其液體混合物便會迅速膨脹,膨脹后泡沫的體積可達其初始體積的40倍,最后便形成一層固化的泡沫層。這個過程可在短短的15 min內(nèi)完成。而高密度的泡沫則用于車身重要結(jié)構(gòu)件(如梁、柱)的補強。其緩速膨脹的特點能使注人的液體混合物有足夠的時間流經(jīng)并填滿中空結(jié)構(gòu)。它膨脹之后的體積只為其初始體積的10倍左右,經(jīng)過30 min,就會完全固化。

       建筑丁基防水嵌縫膠是用于建筑物各種接縫或孔洞的密封,以阻止氣體、液體、固體透過,防止結(jié)構(gòu)材料在結(jié)構(gòu)位移時被破壞,從而起到保溫、隔聲、防水、防塵、防氣、防火、防腐蝕、減震和防止接縫聚積異物的功能。建筑丁基防水嵌縫膠可按其組成分類,現(xiàn)今已有聚硫橡膠、氯丁橡膠、丙烯酸、聚氨酷、丁基橡膠、硅橡膠、橡塑復合型、熱塑性彈性體等多種;也可按施工形態(tài)分為熱涂型、冷涂型、固化反應型和溶劑揮發(fā)型等;還可按用途分為門窗用、嵌縫用、防水防震用、預制墻體用等。隨著丁基防水嵌縫膠成為幕墻結(jié)構(gòu)粘結(jié)裝配用結(jié)構(gòu)材料,國家和企業(yè)逐漸加大此方面投人,目前我國年產(chǎn)量已達6萬t左右,形成了以聚硫、丙烯酸、硅酮和聚氨酷等丁基防水嵌縫膠為主體的新興產(chǎn)業(yè)。http://www.m.n5224.cn/
