(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.

裂縫清理:裂縫切割后需采用高壓氣體噴灑設備,須配備有效的清除空氣中雜物的油濾,并可輸出清潔干燥、連續、高容量、高氣壓氣流的空氣。每條裂縫周邊和裂縫槽內至少進行兩遍高壓噴氣流清理。第一遍清除裂縫雜物時,噴嘴應在距離裂縫不大于5 cm的位置。第二遍距離可以較遠些,以便清除裂縫和裂縫周邊的所有松散穎粒和雜物;
裂縫填封灌注:硅烷改性聚氨酯密封膠填封材料在清縫工序完成后立即灌注,硅烷改性聚氨酯密封膠填封材料需具有雙層保溫性。當硅烷改性聚氨酯密封膠達到規定溫度后,用灌縫機上的噴槍把膠均勻灌注到開槽后的裂縫表面內。灌縫材料通過灌縫機加熱融化后,通過噴槍輸送,灌注在清理過的槽口內,灌注時要自上而下充分填滿,應避免在填料下部產生氣穴,每條裂縫的灌注工作是連續的,如出現未充分填封的裂縫須再次進行填封處理。灌注后的表面與路面找平,也可以適當低于路面應控制在1 mm以內,灌注抹油寬度5 cm;
外觀清理:冷卻5 min-10 min,至裂縫表面的硅烷改性聚氨酯密封膠完全凝固,打磨處理表面,使外觀平整、美觀。撤去施工警示裝置,開放交通。
注意事項
a)開槽深度保證2 cm
b)填縫時室外路面最低氣溫應保證不低于10℃;
c)為確保填縫料與路面結合,開槽后務必保證裂縫表面清理干凈。以防止填縫料與路面之間有雜物,影響結效果,
d)確保硅烷改性聚氨酯密封膠的加熱溫度不低于190℃,不高于240℃,出料溫度不低于190℃,溫度過高時硅烷改性聚氨酯密封膠老化變質,降低使用性能,溫度過低則無法操作,
e)灌縫貼縫后開放交通時間必須在30 min以后,確保一定的結合時間。http://www.qianjin8.cn/
