(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.

由于光伏組件需要固定在露天場(chǎng)所中，且面板與支架連接有一定傾斜角度，盡可能最大程度的吸收太陽(yáng)光達(dá)到其發(fā)電的作用。硅烷改性聚氨酯密封膠將掛件與光伏面板粘接成一體，掛件再與支架連接，所以密封膠起到了結(jié)構(gòu)粘接的作用，其受力形式多樣且方向復(fù)雜。符合ETAG002標(biāo)準(zhǔn)的硅烷改性聚氨酯密封膠由于通過(guò)了疲勞試驗(yàn)、蠕變?cè)囼?yàn)、抗撕裂試驗(yàn)的測(cè)試，可以驗(yàn)證疲應(yīng)力、長(zhǎng)期剪切和拉伸載荷共同作用下的蠕變，以及抵抗撕裂能力對(duì)密封膠性能的影響。其中撕裂試驗(yàn)是評(píng)估硅烷改性聚氨酯密封膠切口后的抗撕裂能力及切口的延伸方式，蠕變?cè)囼?yàn)是判定硅烷改性聚氨酯密封膠在長(zhǎng)期剪切與拉伸載荷作用下的蠕變情況。要求力卸載24 h后試樣在水平方向上的位移不超過(guò)0.1 mm蠕變?cè)囼?yàn)尤為重要，它能針對(duì)硅烷改性聚氨酯密封膠承受所有應(yīng)力(包括玻璃的自重)的玻璃板塊類型(無(wú)支撐)，沒(méi)有設(shè)置用于降低粘接失效產(chǎn)生危險(xiǎn)的安全裝置，與光伏組件掛鉤式安裝類似，對(duì)硅烷改性聚氨酯密封膠持續(xù)受力下的性能有極高的要求。除此以外的其它類型都是需要設(shè)置安全裝置的(有支撐)，風(fēng)載、震動(dòng)及玻璃自重等應(yīng)力由硅烷改性聚氨酯密封膠和支撐共同承受，對(duì)硅烷改性聚氨酯密封膠的要求相對(duì)較低，一些光伏組件廠家更關(guān)注用于無(wú)支撐安裝的硅烷改性聚氨酯密封膠的蠕變性能。http://m.shjishui.com/
