(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.

首先，做好基層處理。應用專用清洗劑或清水、軟布擦拭門窗縫隙、單組分聚氨酯密封膠打膠區的油污、灰塵等雜質，直到表面干燥、清潔。檢查門窗縫隙有無銹蝕、損壞等情況，一旦發現問題，應第一時間修復處理。其次，安裝膠槍。施工過程中檢查膠槍是否完整，避免出現漏氣、堵塞等情況。將單組分聚氨酯密封膠裝人膠槍內，應嚴格按照單組分聚氨酯密封膠使用說明書進行安裝，保證單組分聚氨酯密封膠、膠槍配合緊密。再者，打膠施工。施工前依據門窗縫隙的寬度、深度合理選擇膠嘴，將其安裝在膠槍上。打膠施工中，由門窗縫隙的一端開始，均勻、不間斷地打膠，保證單組分聚氨酯密封膠無斷裂、無氣泡，打膠寬度應控制在7mm-8mm。同時，嚴格控制膠槍的出膠量，不可過多或過少，以免影響密封效果。最后，壓縫處理。打膠完成后，第一時間使用壓縫工具或手指順沿打膠部位緩慢壓實，使單組分聚氨酯密封膠、門窗材料充分接觸，能夠排除氣泡。壓縫過程中，應持續、均勻地進行，不可出現空隙或斷膠情況。

完成上述操作后，按照單組分聚氨酯密封膠的說明書，結合工程實際情況確定固化時間。該工程單組分聚氨酯密封膠初步固化時間24h，完全固化需要7d。固化過程中應保證施工區域干燥，通風性良好，單組分聚氨酯密封膠不可受到陽光直射，以免影響固化的效果。固化結束后，應進一步檢查單組分聚氨酯密封膠的均勻性、連續性且無氣泡、裂縫等問題。通常情況下，固化后的單組分聚氨酯密封膠應足夠平整、不間斷，無裂縫或氣泡現象。http://www.www.machasoul.com/
