(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.

粘貼美紋紙
正確的美紋紙粘貼有助于保護接縫周邊不受污染。粘貼時應注意距離,以避免揭除過程中損壞己施工的膠體。
底涂的使用
在粘接基層表面涂布底涂,在國外屬于丁基防水嵌縫膠施工的標準工藝。正確使用與丁基防水嵌縫膠相配套的底涂可發揮以下作用:D增強丁基防水嵌縫膠與基層之間的粘接力,防止界面粘結破壞;強化混凝土表面的薄弱層,提高基面整體性;封閉混凝土等多孔基材表面,防止基層內部的水分、水蒸氣或堿性物質向丁基防水嵌縫膠層遷移;對于雙組分改性硅酮丁基防水嵌縫膠,其本身在未固化前缺乏自粘性,必須配合底涂實現與基層的有效粘接。
盡管國內受傳統施工習慣影響,工程中普遍未使用底涂,但鑒于混凝土基材的多孔性和表面復雜性,為確保長期密封性能,建議在丁基防水嵌縫膠施工前,于粘接基層表面涂布專用配套底涂,以提升粘接耐久性和整體工程質量。
施膠、修飾
施膠過程中應確保膠縫填充飽滿,不留空腔。一旦出現空腔,后續即使壓實或補膠亦難以保證膠體密實。施膠完成后,應及時使用刮刀或壓板對丁基防水嵌縫膠進行壓實和修飾,確保膠體密實且與基材充分接觸、粘接牢固,并形成平整、均勻的表面輪廓。該工序為密封施工的關鍵環節,必須嚴格操作,確保施工質量。
收尾工作
完成施膠后,及時揭除美紋紙并清理施工機具,保持施工現場整潔有序。
工程應用案例
總部基地核心區“兩站一街”范圍內,南臨北京亦莊經濟技術開發區,西接中關村科技園光機電一體化產業基地。該項目中2#,3#,5#,9#,11#等裝配式住宅樓的外墻預制混凝土接縫、樓梯間混凝土接縫及陽臺等部位均采用丁基防水嵌縫膠進行密封處理。http://www.kzgjfl.cn/
