(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.

根據(jù)表中的可靠性壽命計(jì)算結(jié)果，車窗MS密封膠維修質(zhì)量異常動車組的MS密封膠壽命低于正常情況壽命的夸，維修質(zhì)量最差車廂MS密封膠壽命低于正常情況壽命的專，維修質(zhì)量對車窗MS密封膠壽命存在巨大影響。

根據(jù)中車青島四方相關(guān)技術(shù)研究與日常檢修維護(hù)經(jīng)驗(yàn)，保證車窗MS密封膠維修質(zhì)量有以下要點(diǎn):

(1)底涂劑涂刷前使用合適的清潔劑清潔粘接面;

(2)使用MS密封膠配套底涂劑，并按標(biāo)準(zhǔn)均勻涂刷底涂并進(jìn)行干燥;

(3)按比例調(diào)配MS密封膠主劑與固化劑并及時(shí)使用;

(4)按照環(huán)境溫度選擇對應(yīng)固化劑調(diào)配MS密封膠;

(5)MS密封膠涂打完成后晾膠48 h，期間不得動車、洗車;萬方數(shù)據(jù)

(6)晾膠期間保證環(huán)境溫度在10}40℃，溫度過低時(shí)應(yīng)進(jìn)行輔助加熱。

當(dāng)前執(zhí)行標(biāo)準(zhǔn)中晾膠時(shí)間為24 h，不得動車時(shí)間為12 h，晾膠溫度要求為)5 ℃，均低于上述要點(diǎn)，可能因MS密封膠固化未完成導(dǎo)致動車后MS密封膠質(zhì)量下降，建議改進(jìn)當(dāng)前作業(yè)標(biāo)準(zhǔn)或改用快速固化的MS密封膠。

當(dāng)前MS密封膠涂打標(biāo)準(zhǔn)要求MS密封膠涂打厚度與寬度均勻，現(xiàn)車檢查質(zhì)量異常動車組存在多處MS密封膠不均勻，且無二次維修痕跡，如圖5所示，該動車組上次五級修出廠MS密封膠涂打不符合要求，建議五級修維修部門嚴(yán)格落實(shí)作業(yè)標(biāo)準(zhǔn)，提高維修質(zhì)量。http://cs535.com/
