(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.

       外墻拼縫質量檢測設備研發及操作方法,如前所述,基于《裝配式混凝土結構檢測標準》T/CECS 1189-2022在檢測外墻拼縫丁基防水嵌縫膠的粘結質量時,人為沿縫割離丁基防水嵌縫膠需要在膠體發生內聚破壞之前進行,但實際操作中,判斷割離時機的準確性難以保證。盡管內聚破壞是關鍵標志,但在剝離過程中卻無法直接參考。此外,丁基防水嵌縫膠自由段長度因膠體受力伸長、人為割離及粘結破壞等多種因素影響,變化復雜,難以通過觀察或測量其長度來確定內聚破壞的臨界點或最佳割離時機。綜上,實際應用中,檢測設備需解決以下關鍵問題:①能夠準確顯示出自由段膠體所受拉力值;②檢測對象包括豎向與水平縫,設備需具備靈活的方向調整能力;③檢測通常在高空施工吊籃上進行,屬于高空作業,設備需克服丁基防水嵌縫膠剝離時的反作用力并實現臨時固定。

       為解決這些不確定性和操作難題,本課題組研發了一款專用的外墻拼縫丁基防水嵌縫膠粘結質量檢測裝置。該裝置操作簡便,能夠滿足外墻拼縫中豎向縫和水平縫的剝離檢測需求,并實時顯示自由段膠體所受拉力值。該檢測裝置主要由箱體、微型卷揚機、鋼絲繩、夾具和轉向平臺組成,其中箱體內安裝有包含線盤和減速電機的微型卷揚機,鋼絲繩一端通過箱體上的走線過口和定滑輪與夾具連接,轉向平臺則通過轉向底板和可鎖固的轉向塊調整剝離方向,如圖所示。

       這種設計賦予設備便攜性、通用性和高效性等優點。箱體可移動,無需在墻體上打孔,避免結構破壞,通過調整轉向平臺,定滑輪可沿水平或垂直方向布置,適用于不同方向的拼縫檢測,微型卷揚機配合減速電機,延長鋼絲繩收放線行程,提高檢測效率。在外墻拼縫防水構造措施施工結束后,若腳手架尚未拆除,可將箱體置于腳手架平臺實施檢測,若腳手架已拆除,則可利用施工吊籃平臺實施檢測。然后放出鋼絲繩,使夾具夾持待檢測拼縫丁基防水嵌縫膠的端部,啟動微型卷揚機,通過減速電機驅動線盤收線,鋼絲繩經夾具對丁基防水嵌縫膠施加剝離力,完成檢測。減速電機配備編碼器,可記錄轉動圈速和角度,計算鋼絲繩收放線長度,提升操作精度。http://www.kzgjfl.cn/
