(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.

Information
預(yù)測(cè)試
(1)在現(xiàn)場(chǎng)將加載裝置安裝在待測(cè)MS密封膠側(cè)面，高度宜在玻璃板塊高度中點(diǎn)。安裝位置應(yīng)與有限元分析時(shí)一致。
(2)力傳感器、位移傳感器置零，分級(jí)施加荷載至測(cè)試荷載，每級(jí)荷載維持10s,測(cè)試荷載維持1 mimo測(cè)量記錄各級(jí)荷載、玻璃和鋁框間的相對(duì)位移。
(3)重復(fù)以上試驗(yàn)過(guò)程，并檢查二次變形值差是否過(guò)大。
(4)故意切穿MS密封膠接縫(切割長(zhǎng)度逐步增加)，在切穿處重復(fù)上述加荷試驗(yàn)步驟，以確定MS密封膠遭到破壞的初始試驗(yàn)撓度/fD和切割長(zhǎng)度乙。MS密封膠縫的切割長(zhǎng)度乙以加載點(diǎn)處出現(xiàn)明顯的撓度變化為準(zhǔn)。
(5)重復(fù)上述試驗(yàn)步驟以確定集中荷載值、MS密封膠粘結(jié)面未遭受破壞時(shí)的初始試驗(yàn)撓度MS密封膠遭受破壞時(shí)的初始試驗(yàn)撓度/fD和相應(yīng)的故意切割長(zhǎng)度。
正式檢測(cè)
(1)對(duì)其它玻璃分格相同、MS密封膠規(guī)格和種類(lèi)相同的待測(cè)MS密封膠，按上述預(yù)測(cè)試試驗(yàn)步驟進(jìn)行試驗(yàn)，測(cè)量MS密封膠的撓度變化。
(2)如MS密封膠粘結(jié)面質(zhì)量存在外觀缺陷，加載點(diǎn)應(yīng)布置在缺陷處附近。
(3)試驗(yàn)過(guò)程中出現(xiàn)撓度超過(guò)初始測(cè)定撓度/fD時(shí)，應(yīng)對(duì)撓度增加的原因進(jìn)行分析。排除非粘結(jié)面破壞機(jī)理等因素。
檢測(cè)結(jié)果判定
如MS密封膠的撓度未超過(guò)初始試驗(yàn)撓度可判定粘結(jié)面質(zhì)量合格。http://m.hbxqtax.com/
