(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.

Information
對(duì)于陽臺(tái)、空調(diào)板、飄窗、落水管位置等連接復(fù)雜位置，應(yīng)上下部同時(shí)打膠，防止處理不到位引起后期墻體滲水。對(duì)于淺色或特殊顏色的丁基防水嵌縫膠應(yīng)避免與酸性或堿性物質(zhì)接觸(比如外墻清洗液等)，否則可能導(dǎo)致丁基防水嵌縫膠表面發(fā)生變色。
本文對(duì)裝配式建筑墻體丁基防水嵌縫膠所需性能進(jìn)行了研究，并對(duì)現(xiàn)有常用丁基防水嵌縫膠性能進(jìn)行了對(duì)比，針對(duì)提出不同的使用需求，提出了丁基防水嵌縫膠的選用方法，并針對(duì)目前設(shè)計(jì)、施工存在問題，總結(jié)提出了丁基防水嵌縫膠的設(shè)計(jì)施工要點(diǎn)。丁基防水嵌縫膠的選用方法總結(jié):
(1)優(yōu)先選用改性硅酮丁基防水嵌縫膠，因?yàn)槠渚C合性能最佳。
(2)有涂裝要求時(shí)，不能選用硅酮丁基防水嵌縫膠，宜選用中性改性硅酮丁基防水嵌縫膠。
(3)當(dāng)裝配式建筑外墻采用清水混凝土，且對(duì)丁基防水嵌縫膠耐候性要求較高時(shí)(耐久性不少于20年)，建議優(yōu)先采用中性硅酮丁基防水嵌縫膠。
(4)當(dāng)墻體接縫為非位移縫時(shí)應(yīng)選用20級(jí)及以上位移能力的建筑丁基防水嵌縫膠，當(dāng)接縫為位移縫時(shí)，應(yīng)選用25級(jí)及以上移能力的建筑丁基防水嵌縫膠。
(5)當(dāng)工期較緊或膠縫寬度不小于30 mm或膠縫深度不小于15 mm時(shí)，宜選用雙組分丁基防水嵌縫膠。
(6)當(dāng)接縫位于水平面時(shí)，應(yīng)選擇自流平型丁基防水嵌縫膠;當(dāng)接縫位于非水平面時(shí)，應(yīng)選擇非下垂型建筑丁基防水嵌縫膠。http://hbxqtax.com/
