(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.

防水和粘結施工等方面,本文就其在混股土防水誰工中的應用進行總結云以期為令后類似工聚氨酯密封膠是一種新型粘接材料,具有良好的耐候性、水密、氣密性、防水效果好等諸多優點,廣泛應用于沉降縫和變形縫的密封、防水施工,以及金屬或玻璃的氣密、水密嘟由密粘結施工等方面。
施工準備葉基層修整、清掃--1填塞背襯材料卜卜貝占防污條一卜涂底涂料,混料弓裝注膠槍并嵌填一夠平壓光升除防污條、清理縫邊葉養護(襯做保護層)。
聚氨酯密封膠由A組份(白色基膏)和日組份(黑色硫化膏)組成,其摻加比例為A:B二100:8-100:12,氣溫高時適當減少B組份用量,反之增加用量,但不宜加量過多,以防固化過快而影響粘結弓雖度,甚至反硫化。配制好的聚氨酯密封膠活險期一般為1-8小時。
應在底涂料涂刷后的千燥期內進行,了影交過早會因等待底涂料干燥而縮短聚氨酯密封膠的有效使用期,甚至固化失效而造成浪費;過晚會拖延工時。;翩交宜采用機械攪拌,將A, B組份倒入攪拌桶內,插入電動攪拌器低速、自上而下進行攪拌。每攪拌2-3min停一下,用刮刀將粘附在底、壁上的材料刮至)混合料中重新攪拌直至均勻。交采用人工弓昆合時,可將A.B兩組份倒在玻璃板上,用批刀來回批抹直至均勻。攪拌均勻的混合料應顏色一致、無色差,檢查方法:用膩子刀將混合料在平面上刮薄,如無不同顏色的斑點或條紋,即拌勻。
將中間帶有出膠孔和推力桿的壓膠盤里入攪拌好的膠面上。取下槍管前、后螺蓋,槍口對潤到交盤出膠口,手握槍管和推力桿,用力下壓,將膠注入槍管至灌滿,安裝槍管前、后螺蓋,完成裝槍。www.caffertyclinic.com
