(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.

某項目使用單組分MS密封膠，MS密封膠注膠深度為lOmm，在低溫條件下，完全固化所需的時間可能是常溫下的2倍一3倍甚至更長。

另外，通風條件和空氣濕度也對單、雙組分MS密封膠的固化過程產生影響。良好的通風條件對單、雙組分的固化和粘接過程均比較有利。空氣濕度過低(低于50%)或過高(高于90%)都將對MS密封膠的固化產生不利的影響。此時應加強質量控制，并通過割膠試驗密切關注MS密封膠的固化及粘接情況。

本文結合具體的案例，從粘接性試驗、施工工藝、設計、材料、MS密封膠注膠環(huán)境和養(yǎng)護環(huán)境等方面對于結構MS密封膠與基材的粘接問題進行了系統(tǒng)的原因分析，并給出了對應的解決方案。

在設計過程中，應對膠縫尺寸、寬厚比和膠縫封閉情況予以充分的考慮，有需要時可向MS密封膠生產廠家溝通確認。在施工過程中，應提前做好粘接性試驗，按推薦的施工工藝施工，同時規(guī)范清洗、打底涂、MS密封膠注膠等施工操作。

在結構MS密封膠應用過程中，重視以上環(huán)節(jié)可獲得理想的粘接效果，大幅度減少粘接不良問題的發(fā)生。隨著新能源汽車車身結構設計向著多樣性、復雜性的方向發(fā)展，對MS密封膠的施工工藝及性能要求越來越高。文章介紹了MS密封膠工藝，分析了新能源汽車車身涂裝中MS密封膠常見的開裂、膠泡、褶皺、雜質等質量缺陷問題，對問題發(fā)生的原因進行了分析研究，并結合筆者工作經驗提出幾點優(yōu)化措施，旨在為相關領域研究人員提供參考借鑒。http://www.www.sunsage.net/
